 BULLIUM CHLORIDE RESIN COMPOSITION AND MOLDED BODY

 Technical field

 [0001] The present invention relates to a chlorinated bur resin composition capable of forming a transparent and flame-retardant molded article, and a molded article obtained by molding the composition.

 Background art

 [0002] Chlorinated chlorinated resins contain chlorine in the molecule and are not only excellent in flame retardancy, but also have a wide range of additives, so mechanical properties, heat resistance, moldability The weather resistance can be adjusted over a wide range and has been used for various purposes. For example, molded products of rigid chlorinated resin-based resin compositions are interior and exterior materials for transportation equipment such as aircraft, ships and vehicles; interior and exterior materials for buildings; daily necessaries such as furniture and office equipment; housing for home appliances and electronic devices. Materials: Used as parts of semiconductor devices.

 However, when chlorinated resin is exposed to a temperature higher than the heat-resistant temperature due to a fire or the like, a large amount of smoke is generated due to chlorine in the molecule, and a toxic gas such as chlorine gas or hydrogen chloride gas is generated. Is generated. For this reason, attempts have been made to suppress the generation of toxic gases by examining the types and amounts of additives.

 [0004] For example, in Patent Document 1, for the purpose of a transparent chlorinated resin based on FM standards, a zinc compound is converted into an amount of metallic zinc per 100 parts by weight of chlorinated resin. A transparent flame-retardant chlorinated chlorinated resin molded article containing 5 parts by weight and 0.5 to 7 parts by weight of a tin stabilizer and molded into a desired shape is disclosed.

 However, with this disclosed technology, sufficient flame retardancy cannot be ensured, and depending on the processing conditions, there is a possibility of poor appearance such as poorly dispersed burn derived from the zinc compound of the powder, and inferior lubricity and thermal stability. Molding processability is bad! Therefore, the improvement is desired! /.

[0005] Further, Patent Document 2 discloses that a transparent chlorinated bulle-based resin molded body having flame retardancy is laminated with a low chlorinated bulle layer and a high chlorinated bulle layer. There is disclosed a transparent flame retardant chlorinated resin-based resin molded body having an average chlorination degree of 60% or more and formed into a desired shape. However, in this disclosed technology, since resins having different compositions are laminated, there is a problem that a difference in refractive index is generated at the resin interface, and it is difficult to obtain high transparency, and the process becomes complicated and productivity does not increase. In order to increase productivity, if a single layer is used, it will be difficult to ensure sufficient transparency as well as insufficient flame retardancy.

[0006] Further, Patent Document 3 discloses that in a chlorinated resin-based resin composition containing an organotin stabilizer, an organozinc compound as a high-temperature decomposition accelerator in an amount of 0.01 to 0.01 mass! In particular, a chlorinated bur resin composition and a molded product obtained from the same are disclosed. Transparency and flame retardancy can be secured, but in addition to further improvement in transparency and flame retardancy, improvement in processability is expected.

 [0007] As described above, it has been difficult for the conventional chlorinated resin molded body of resin to satisfy high productivity as well as high transparency and flame retardancy.

 Problems to be solved by the invention

[0009] The present invention relates to a chlorinated bur resin resin composition having excellent transparency and flame retardancy, thermal stability and lubricity necessary to ensure high productivity, and a molded article obtained therefrom. The purpose is to provide.

 Means for solving the problem

[0010] For this purpose, the present inventor has 1 to 50 parts by mass of a chlorine-containing resin having a high-temperature decomposition accelerating function and an organic compound having a high-temperature decomposition inhibiting function for 100 parts by mass of a chlorinated resin. ; ~ 7 parts by mass, thermal stabilizer with low-temperature decomposition inhibitory function (including thermal stabilization aid)

1 to; Proposed a chlorinated bur resin composition and a molded body thereof containing 10 parts by mass.

[0011] According to the chlorinated resin resin composition of the present invention, a chlorine-containing resin having a high-temperature decomposition promoting function. By virtue of the synergistic effect of the decomposition promoting function of the resin-containing resin and the decomposition inhibiting function of the organic compound having the high-temperature decomposition inhibiting function, it is excellent in flame retardancy, and the inherently chlorinated buyl chloride resin has V, ! /, Transparency can be maintained at the same level, and high! /, Thermal stability and lubricity necessary to ensure productivity are excellent. The molded article of the present invention obtained by extrusion molding, calender press molding or extrusion continuous press molding of such a salted bull resin composition is excellent in transparency and flame retardancy, and has high productivity.

 BEST MODE FOR CARRYING OUT THE INVENTION

 [0012] Hereinafter, it is obtained by molding the bull chloride resin composition (hereinafter referred to as "the present bull chloride resin composition") as an example of the embodiment of the present invention, and the present bull chloride resin composition. The molded body (hereinafter referred to as “main molded body”) will be described. However, the scope of the present invention is not limited to the embodiments described below.

 [0013] The present chlorinated bur resin composition contains a high temperature decomposition accelerator, a low temperature decomposition inhibitor and a high temperature decomposition inhibitor in addition to the chlorinated resin as a base resin. System resin composition.

 [0014] Here, the high temperature decomposition accelerator is a substance having a function of promoting the decomposition of the chlorinated resin in the high temperature region, and the high temperature decomposition inhibitor is an agent that inhibits the decomposition of the chlorinated resin in the high temperature region. A low-temperature decomposition inhibitor is a substance that has a function of suppressing the decomposition of a chlorinated resin in a low temperature region.

 In terms of the decomposition behavior of chlorinated resin, the dehydrochlorination behavior starts from the processing temperature range up to 220 ° C, and the dehydrochlorination behavior is prominent around 220 ° C to 370 ° C. This is the temperature range that occurs. Above this temperature range, for example, 450 ° C or higher, the main chain of the chlorinated resin may be broken, or carbon of the chlorinated resin may be burned or carbonized. Therefore, in the present invention, the decomposition in the low temperature region refers to the decomposition behavior in the temperature range up to 220 ° C., which is the forming temperature range, and the decomposition in the high temperature region means that the main chain is broken. Decomposition behavior in the temperature range above 450 ° C where carbon combustion occurs.

In addition, the high-temperature decomposition promoting function in the present invention means that the chlorinated resin is 450 ° C or higher. Therefore, it can be said that this function promotes decomposition by breaking the main chain of the chlorinated resin and carbonization by combustion of carbon in the chlorinated resin. In addition, the high-temperature decomposition inhibiting function in the present invention can be said to be a function of inhibiting the decomposition and carbonization of the chlorinated bur resin at 450 ° C. or higher. Furthermore, it can be said that the low-temperature decomposition inhibiting function in the present invention is a function that inhibits the start of dehydrochlorination behavior from a chlorinated bur resin at less than 220 ° C.

[0015] (Buluric chloride resin)

 Examples of the vinyl chloride resin that can be used as a base resin in the present chlorinated resin composition include homopolymers of chlorinated chloride and copolymers of chlorinated chloride and other bulle compounds. Can be used alone or as a mixture of these two.

 [0017] In the above-mentioned copolymer, if the copolymerization amount of the other bulu compound does not exceed 30% by mass, the inherent flame retardancy and high transparency of the chlorinated bur resin will not be impaired. The bull compound is preferably contained in a range not exceeding 30% by mass. The amount of copolymerization is preferably 20% by mass, more preferably 10% by mass, from the viewpoints of transparency and flame retardancy.

[0018] The average degree of polymerization of the chlorinated resin is preferably 300 to 2,000, more preferably 500 to 1,500. If the average degree of polymerization is too small, the molded product may not have sufficient strength. If it is too large, it is difficult to sufficiently knead the molded product during molding. May decrease.

[0019] As the chlorinated resin, those polymerized by various methods such as an emulsion polymerization method, a suspension polymerization method, a bulk polymerization method and the like, which do not particularly limit the polymerization method, can be used.

 [0020] (High-temperature decomposition accelerator)

 The high-temperature decomposition accelerator is effective in reducing the amount of smoke generated in the high-temperature region by promoting the cleavage and carbonization of the main chain of the chlorinated bur resin during combustion of the molded body (for example, 450 ° C or higher). It is a plus.

 [0021] As the high-temperature decomposition accelerator, a chlorine-containing resin capable of generating hydrogen chloride, which has an action of promoting the cleavage of the main chain of the chlorinated resin, is preferred.

The amount is 58 to 70% by weight, preferably 60 to 70% by weight. If the average chlorine content is too low, the heat resistance will be reduced and deformation will occur, and if it is too high, especially if it exceeds 70 mass%, the fluidity will be greatly reduced and molding will be difficult.

Deterioration of warm water whitening will occur. Therefore, the content of the high-temperature decomposition accelerator is 5 to 30 parts by mass, especially 10 to 20 parts by mass, even though! To 50 parts by mass is preferable with respect to 100 parts by mass of the chlorinated resin. I like it!

 This chlorinated resin-based resin composition can be processed into a main product by molding it into a shape of a film, sheet, plate, pipe, odd-shaped product, etc. by extrusion molding, calendar molding, press molding method or continuous press molding. it can.

 [0047] Of the above molding methods, the calendar press molding method is a molding method under mild conditions, and therefore, an organotin stabilizer with a wide range of selection of a stabilizer having a low-temperature decomposition inhibiting function. Satisfactory metal calcite stabilizer, zeolite, hydrated talcite, aluminum and magnesium hydroxides alone or in combination of two or more.

In the calendar press molding method, a thin plate can be preferably molded at the calendar molding stage. In order to obtain a plate having a desired thickness, a plurality of plates are laminated at a press molding stage to obtain a desired thickness. Therefore, the calendar press molding method changes the thickness of the molded body without requiring a major change in the molding machine when changing the thickness of the molded body. Can be.

 [0048] Further, in the calendar press molding method, a plurality of plates obtained in the calendar molding stage are laminated in the press molding stage to obtain a plate having a desired thickness, but a plurality of plates obtained in the calendar molding stage are used. The body has a certain degree of thickness fluctuation due to molding conditions, etc., and this thickness fluctuation is combined with thickness fluctuation caused by conditions at the press molding stage, resulting in poor thickness accuracy. Yes.

 [0049] On the other hand, the extrusion molding method is a molding method under severe conditions of high temperature and high pressure compared with the calendar press molding method, and therefore, the selection range of a stabilizer having a low temperature decomposition inhibiting function is narrow. It is necessary to use tin stabilizers, metal stone stabilizers, zeolite, hydrated talcite, aluminum-based and magnesium-based hydroxides in combination. A suitable combination includes a combination of an organic tin stabilizer and one or more of zeolite, hydrated talcite, and magnesium hydroxide.

 In the extrusion molding method, there is no problem that a so-called rebound phenomenon occurs, and a plate having a desired thickness can be obtained by one extrusion, so there is no problem of delamination (solvent resistance).

 In the extrusion molding method, by adjusting subtle fluctuations in extrusion conditions, subtle fluctuations in conditions when drawing out the extruded plate, etc., the wavy phenomenon occurs in the plate and the thickness does not become uniform. It is possible to prevent problems.

[0050] In addition, the continuous extrusion press molding method has no problem of wrinkling and delamination (solvent resistance), and the extruded plate is pressed subsequent to extrusion, so the wavy phenomenon is This is a particularly preferable molding method in that a plate having a desired thickness can be obtained with high thickness accuracy.

 Examples of the low-temperature decomposition inhibitor suitably used in the extrusion continuous press molding method include organotin stabilizers, anodic talcite, magnesium hydroxide, and the like.

[0051] (Formed body)

In general, the flame retardancy of a flame retardant chlorinated resin molding can be evaluated using a cone calorimeter in accordance with ASTME1354. The flame retardant properties evaluated by the combustion test using a corn calorimeter include the maximum calorific value due to combustion per unit area and unit time (maximum calorific value, also referred to as PHRR; unit: kW / m ² ), Average value of calorific value by combustion per unit area and unit time (average heat rate, also described as AHRR; unit: kW / m ² ), total heat value by combustion (also described as total heat value, THR; unit: Mj / m ² ), average value of mass reduction rate due to combustion per unit area and unit time (also referred to as mass reduction rate, AMLR; unit: g / sec 'm ² ), reduction due to combustion per unit area and unit time Maximum value of light volume (maximum dimming volume, also described as PSEA; unit: m ² / g), average value of light volume due to combustion per unit area and unit time (average specific dimming area, also described as ASEA) (Unit: m ² / kg).

 [0052] Conventionally, as one of the flame retardant indicators, evaluation criteria established by the Industrial Mutual Insurance Organization (Factory Mutual System) have been used effectively. This evaluation standard was measured based on the Clean Room Materials Flammability Test Protocol (FMRC) listed as ClassNumber 4 910, and the flame spread index FPI indicating smoke resistance, and the smoke index indicating smoke generation SDI, corrosion index CDI indicating corrosive gas generation, etc. are used as indicators (also described as FM standards).

 In the present invention, instead of the FM standard, a value evaluated by a combustion test using a corn calorimeter is used as an indicator of flame retardancy. The FM standard is a standard obtained by submitting test specimens to the industry mutual insurance organization and evaluating the industry mutual insurance organization, so it takes time to obtain the evaluation results and is inefficient. The combustion test using the corn calorimeter is efficient because it can be performed by the inventors.

 In particular, FPI has a strong correlation with indices related to calorific values such as PHRR, AHRR, and THR measured by a corn calorimeter. In addition, SDI has a strong correlation with indicators related to dimming volume such as PSEA and ASEA. Moreover, CDI has a strong correlation with mass loss indicators such as AMLR.

 Therefore, by evaluating the flame retardancy using a corn calorimeter, the approximate value of the FM standard can be obtained efficiently.

[0053] According to FM standards, FPI is required to be 6 or less and SDI is required to be 0.4 or less! In this case, PHRR is 130kW / m ² or less, AHRR is 65 kW / m ² or less, THR force OOMj / m ² or less, AMLR is 13g / sec 'm ² or less, PSEA is 1500m ² / It is preferable that the ASEA is 800 g ² / kg or less.

[0054] The upper limit of the average heat release rate (AHRR) measured according to AS TME1354 of the molded product when molded into a thickness of 5 am using this chlorinated resin resin is 65 kW / m ² or less, preferably 50 kW / m ² or less, more preferably 30 kW / m ² or less. In addition, when the resin composition of the present invention is used to mold to a thickness of 5 m, the upper limit of the average specific attenuation area (ASEA) measured according to ASTM E1354 of the molded product is 800 m ² / kg or less It is preferably 600 m ² / kg or less, more preferably 500 m ² / kg or less.

If the average heat generation rate (AHRR) is 65 kW / m ² or less and the upper limit of the average specific attenuation area (ASEA) is S800 m ² / kg or less, the FM standard can be satisfied.

 [0055] In addition, when the bull chloride-based resin composition is used and molded to a thickness of 5 m, the average heating rate (AHRR) and average specific attenuation surface of the molded body measured according to AST ME1354 are measured. In order to adjust the product (ASEA) to a certain range, it is preferable to add chlorine-containing resin having a high temperature decomposition promoting function and to reduce the number of organic compounds having a high temperature decomposition inhibiting function.

 [0056] The molded article has a total light transmittance of 55 to 100%, preferably 65 to 100%, more preferably 70 to 100%, and a haze value of 0 to 20%, preferably 0. It is desirable that the molded body is 10%, more preferably 0 to 5%, particularly when the thickness is 5 mm.

 In this molded product, in order to adjust the total light transmittance and the haze to a preferable range, a chlorine-containing resin having a high-temperature decomposition promoting function and a heat stabilizer having a low-temperature decomposition suppressing function are added as little as possible. It is preferable to adjust.

 [0057] The molded product has not only excellent flame retardancy but also excellent transparency. Therefore, especially by using rigid chlorinated resin moldings, interior and exterior materials for transportation equipment such as aircraft, ships and vehicles; interior and exterior materials for buildings; daily goods such as furniture and office equipment; housings for home appliances and electronic devices Material: Can be used suitably as a component of a semiconductor device

Yes [0058] (Glossary of terms)

 In the present invention, when “Χ to Υ” (X, Υ is an arbitrary number) is described, it is preferably “larger than X and smaller than と 共 に” with the intention of “X or more and Υ or less” unless otherwise specified. The intention to this effect is also included.

 [0059] The inventor has identified a specific organic compound together with a specific high-temperature decomposition accelerator and a low-temperature decomposition inhibitor, particularly an organic compound having an excellent function as a lubricant or a processing aid. When blended with a chlorinated resin such that the ratio is as follows, the following knowledge was obtained and the present invention was conceived based on this knowledge.

 (1) Such an organic compound functions as a high-temperature decomposition inhibitor in a system in which the specific high-temperature decomposition accelerator and the low-temperature decomposition inhibitor coexist.

 (2) Combined with the function as a high-temperature decomposition inhibitor (decomposition-inhibiting function) and the above-described high-temperature decomposition accelerator, the decomposition of the base material resin (Buhl chloride resin) at high temperatures is well controlled. Furthermore, the flame retardant resin is further improved in flame retardancy.

 (3) The other characteristic of the above organic compound is that it functions as a lubricant or processing aid because it does not require the use of ordinary lubricants or processing aids that are generally used in chlorinated resin. Therefore, the high and / or transparency inherent to the chlorinated resin that is impaired by the blending of these auxiliaries can be maintained at the same level.
