Abstract
The invention discloses a method for rapidly testing component precipitation of modified plastics. The method of the invention utilizes the principle that the viscosity of the additive can be reduced and the activity of the additive can be improved at high temperature, so as to accelerate the precipitation speed, and the material is tested at high temperature, and if the material has precipitation phenomenon, the material can also have precipitation phenomenon in the future. The method can be used for rapidly detecting whether the components are separated out from the material or not in the research and development and production stages of the material, does not need a precise instrument, is simple in test method and low in cost, and provides quality guarantee for products.
Description
Technical field
The present invention relates to the method for testing in the production run, relate in particular to the method that a kind of quick test modified plastics component is separated out.
Background technology
In the modified plastics industry; After material often occurring and being injection molded into product, because adjuvant and matrix material polarity is inconsistent or the additive molecule amount is too small, after material is injection molded into the product one-year age; One deck oily white precipitate can appear in the product surface, has a strong impact on the outward appearance of material.For this situation, each material producer all representes helpless at present, is to occur at material 1 year even longer time because separate out phenomenon, can't detect in material development, production phase.A kind of method that does not at present also have a kind of fast detecting material whether to separate out.
Summary of the invention
The objective of the invention is to the problem that exists component to separate out, can't detect according to existing modified plastics, provide a kind of and can just whether separate out the method that component is carried out fast detecting in the research and development and the production phase of material to material in the production phase.
Purpose according to the invention is achieved through following technical scheme:
It is a process slowly that adjuvant is separated out from material.High temperature can increase the viscosity of adjuvant, improves its activity, and then quickens the speed of separating out of adjuvant.The method of the invention is utilized this principle exactly, after manufacture of materials is accomplished, is injection molded into Standard colour board earlier, then standard is moulded plate and heats, and heating-up temperature is than material melting point low 50 ~ 70 ℃ (preferred 50 ℃), if the phenomenon of separating out, then positive result; Separate out phenomenon like nothing, then negative result.Through the detection of said method, if phenomenon has appearred separating out in material after production a year or longer time, then the result that detects of the present invention is positive findings certainly.
As a kind of preferred version, in the said method, the glossiness of said Standard colour board is greater than 80.
As a kind of preferred version, in the said method, the used instrument of said heating is a baking oven, and the time of heating is 12 ~ 15h (preferred 12h).
Compared with prior art, the present invention has following beneficial effect is arranged as follows:
(1) the method for the invention need not exact instrument, and method of testing is simple, and is with low cost;
(2) the method for the invention test speed is fast, can test in the research and development and the production phase of material, just can obtain test result in the short time, for product provides quality guarantee.

Fig. 1 is the schematic flow sheet of method of testing according to the invention.
Embodiment
Embodiment 1
For whether checking adjuvant EBS (0.5 part) separates out in the PP material, with 99.5 parts of PP resins, the potpourri that EBS is 0.5 part is injection molded into Standard colour board.Colour table is placed in the baking oven 100 ℃ of bakings 12 hours, takes out to find not have behind the colour table and separate out.All use 0.5 part of EBS as adjuvant in the follow-up prescription, this formula materials uses in the customers' place, and client's feedback is all normal, and material does not in use have the phenomenon of separating out always.This embodiment proves that this method of testing is feasible.
Embodiment 2
Whether separate out in the PP material for checking adjuvant eight bromines (5 parts), with 95 parts of PP resins, 5 parts of potpourris of eight bromines are injection molded into Standard colour board.Colour table is placed in the baking oven 90 ℃ of bakings 12 hours, takes out colour table and more significantly separate out phenomenon.The precipitate grease that is white in color.The follow-up material that will fill a prescription uses in the customers' place.Phenomenon just appearred separating out in second day in client feedback after the material injection moulding.This embodiment proves that this method of testing is feasible.
Embodiment 3
Whether separate out in the ABS material for checking calcium stearate (0.5 part), with 99.5 parts of ABS resins, the potpourri that calcium stearate is 0.5 part is injection molded into Standard colour board.Colour table is placed in the baking oven 125 ℃ of bakings 12 hours, takes out to find not have behind the colour table and separate out.All use 0.5 part of calcium stearate as adjuvant in the follow-up prescription, this formula materials uses in the customers' place, and client's feedback is all normal, and material does not in use have the phenomenon of separating out always.This embodiment proves that this method of testing is feasible.
Claims (6)
1. test the method that the modified plastics component is separated out fast for one kind; It is characterized in that said method is after manufacture of materials is accomplished, to be injection molded into Standard colour board earlier, then standard moulded plate and heat that heating-up temperature is lower 50 ~ 70 ℃ than material melting point; If the phenomenon of separating out, then positive result; Separate out phenomenon like nothing, then negative result.
2. the method that quick test modified plastics component according to claim 1 is separated out is characterized in that said heating-up temperature is lower 50 ℃ than material melting point.
3. the method that quick test modified plastics component according to claim 1 is separated out, the surface gloss that it is characterized in that said Standard colour board is greater than 80.
4. the method that quick test modified plastics component according to claim 1 is separated out is characterized in that the used instrument of said heating is a baking oven.
5. the method that quick test modified plastics component according to claim 1 is separated out, the time that it is characterized in that said heating is 12 ~ 15h.
6. the method that quick test modified plastics component according to claim 5 is separated out, the time that it is characterized in that said heating is 12h.
