耐老化ABS/PVC共混塑料的研制

以国产丙烯腈-丁二烯-苯乙烯三元共聚物(ABS）、聚氯乙烯(PVC)为主要原料，配以紫外线吸收剂、抗氧剂等助剂，研制了耐老化ABS／PVC共混塑料，并对其加工性能、力学性能及耐老化性能进行了研究。结果表明，在ABS和PVC质量比为60：40，添加抗氧剂1076和紫外线吸收剂UV-327(两者用量均为ABS／PVC共混塑料质量的0.5％)后，所制得共混塑料不仅具有优良的力学性能，而且还具有良好的耐老化性能。

Development of anti-ageing ABS/PVC

A kind of anti-ageing plastic composed of acrylonitrile-butadiene-styrene (ABS)/poly (vinyl chloride) (PVC) was developed with taking ABS, PVC as major raw materials, and taking antioxidants and ultraviolet (UV) absorbers as additives The processing, mechanical and anti-ageing properties of the plastic were also studied. The results show that when the mass ratio of ABS to PVC reaches 60 : 40 and both antioxidant 1076 and UV absorber UV-327 account for 0.5% of the plastic's mass, the blending resultants so prepared possess not only the superior mechanical and processing properties, but also the eminent anti-ageing property.
