The composition is composed of polyvinyl chloride, a plasticizer, an impact modifier, and a heat stabilizer mixed in an appropriate ratio, and an appropriate amount of auxiliary agents (such as a light stabilizer, a lubricant, etc.) are added. The pipe material can be thinned by melt extrusion by adopting the composition, the thickness of the pipe material is between 0.1 mm and 10 mm, has excellent cold resistance and durability, and is suitable for various water delivery pipes of a water-saving irrigation system.
Description
The present invention relates to a kind of polyvinyl chloride of modification, specially refer to polyvinyl chloride and tubing and preparation method with excellent cold-resistant and ageing resistance, this tubing is applicable to the various low-pressure delivery pipes that agricultural water-saving irrigation system is required.
At present, China water resources lacks, in the north and the Northwest more very.According to statistics, China's water total amount over half is used for agricultural irrigation.Adopt traditional big canal irrigation to irrigate, because the loss that channel infiltration and the evaporation of irrigation field are caused reaches 75% of irrigation water.Therefore, water saving should be started with from agricultural, starts with from changing irrigation method.In recent years, China has adopted the method for sprinkling irrigation in many places, introduced external drip irrigation and infiltration irrigation technology simultaneously.The patent of relevant agricultural water-saving irrigation aspect is also more and more, as patent of invention CN98124544.7 (a kind of trickle irrigation equipment) and CN98124543.9 (a kind of anti-clogging plug infiltration is irrigated and device) etc. water saving fixtures are reported, but but very few to the patent report of the essential plastic pipe that uses in the water-saving irrigation system.
Polyvinyl chloride is widely used in making various soft or hard tubing, also being used in water saving irrigation more.But existing polyvinyl chloride water saving irrigation tubing, winter hardiness is poor, is easy to fragmentation; Ageing resistance is poor, and duration of service is short.
The objective of the invention is to overcome the shortcoming of polychloroethylene pipes winter hardiness and ageing resistance difference in the prior art, a kind of polychloroethylene composition is provided, said composition has isostatic rigidity and impact property, has good processibility simultaneously, can make the thin-walled polychloroethylene pipes of use properties excellence, this tubing is applicable to various pipelines required in the water-saving irrigation system.
The invention provides a kind of polychloroethylene pipes composition, said composition tubing comprises following component and content (parts by weight): 100 parts of polyvinyl chloride; Softening agent 5-50 part; Impact modifying agent 1-30 part; Thermo-stabilizer 0.3-10 part; Photostabilizer 0.05-3 part; Lubricant 0.1-2 part; Other auxiliary agent is as interpolations in right amount as required such as tinting materials.
The polymerization degree of polyvinyl chloride is about 800-1700 in the present composition, and the consumption in composition is 100 parts.
Softening agent in the present composition comprises common softening agent such as phthalic ester series, sebate series, adipic acid ester series, as dioctyl phthalate (DOP) (DOP), dibutyl phthalate (DBP), Dinonylphthalate (DNP), dioctyl sebacate (DOS), Octyl adipate (DOA) etc., also comprise phosphoric acid ester and epoxy plasticiser simultaneously.Above-mentioned softening agent can use separately, also can use jointly by two or more softening agent, and in composition, total consumption of softening agent is 5-50 part, and when being lower than 5 parts, polyvinyl chloride can not get plasticization effect; Be higher than 50 parts, resulting composition does not possess enough rigidity.When the polymerization degree of used polyvinyl chloride was low, plasticizer dosage was few; When the polymerization degree of used polyvinyl chloride was higher, plasticizer dosage was more.
Impact modifying agent in the present composition comprises MBS (MBS), chlorinatedpolyethylene (CPE), paracril (NBR), acrylic elastomer (ACR) etc., can use separately or jointly.In composition, its consumption is 1-30 part.
Thermo-stabilizer in the present composition comprises lead salts stablizer, metallic soap class stablizer, organic tin stablizer, phosphite ester stabilizer and epoxy compounds.Typical lead salts stablizer has tribasic lead sulfate (three salt), dibasic lead phosphite (disalt), dibasic lead phthalate, lead stearate etc.; Metallic soap class stablizer has calcium stearate, Zinic stearas, cadmium stearate, barium stearate etc., also comprises the mixture of two or three metallic soap simultaneously, as barium/cadmium/zinc stabilizer, calcium/zinc stabilizer etc.; The organic tin stablizer has dibutyl tin laurate (capital tin C-101), two maleic mono octyl ester di-n-butyltin dilaurates (capital tin LM-103), two (the different monooctyl ester of sulfo-glycolic acid) dioctyltins (capital tin 8831) etc., the mixture that comprises these materials and other kind stablizer simultaneously is as mixture (capital tin C-102) of capital tin C-101 and epoxies stablizer etc.These stablizers can use separately, also can compoundly use.In composition, the consumption of thermo-stabilizer is 0.3-10 part.
Photostabilizer in the present composition, comprise 2-(2 '-hydroxyl-5 '-aminomethyl phenyl) benzotriazole (UVA-6), 2 benzotriazole-2-base-4,6-DI-tert-butylphenol compounds (UVA-7), Octabenzone (UV-531), 2-hydroxyl-4-methoxy benzophenone benzotriazole category ultraviolet absorbers and benzophenone ultraviolet absorbers such as (UVA-9).In composition, its consumption is 0.05-3 part.
Lubricant in the present composition comprises calcium stearate, Zinic stearas, stearic acid, paraffin, clorafin, polyethylene wax, chlorinatedpolyethylene wax etc., can independent or compound use.In composition, its consumption is 0.1-2 part.
In the present composition, can also suitably add auxiliary agents such as tinting material, static inhibitor as requested.
The invention provides a kind of manufacture method of tubing of polychloroethylene pipes composition, be about to 100 parts of polyvinyl chloride, softening agent 5-50 part, impact modifying agent 1-30 part, thermo-stabilizer 0.3-10 part, photostabilizer 0.05-3 part, lubricant 0.1-2 part places super mixer to mix, when temperature of charge reaches 80-100 ℃, stop to mix.Then the material that mixes is added melt mixing equipment forcing machine (single screw extrusion machine, twin screw extruder, double roll mill etc.) and mix, this composition is made the thin-wall pipes that wall thickness is 0.1-10mm through extrusion moulding.Melt temperature is 140-200 ℃, and the extrusion moulding temperature is 160-200 ℃.This composition tubing is applicable to the low-pressure delivery pipe of water-saving irrigation system.
