ABS树脂絮凝过程中抗氧剂添加工艺和絮凝液组成对其性能影响
Effect of Antioxidant Addition Process and Flocculating Liquid Composition on Performance of Acrylonitrile Butadiene Styrene During Flocculation
摘要
Abstract
Waterborne antioxidant is a necessary additive in the flocculation stage of acrylonitrile butadiene styrene(ABS)resin production process,which can improve the thermal oxidative aging of ABS resin.The addition process and flocculation process of waterborne antioxidant have an important influence on the performance of ABS resin.ABS graft copolymer latex with a core-shell ratio of 60∶40 was prepared by emulsion graft polymerization.The effects of temperature of waterborne antioxidant and flocculant composition on thermal oxidative aging properties of ABS graft copolymer were studied.ABS resin was prepared using melt blending technology.The effects of temperature of waterborne antioxidant and flocculant composition on mechanical properties and apparent properties of ABS resin were investigated.The results show that the ABS graft copolymer has better thermal oxidative aging properties when the temperature of waterborne antioxidant is higher than 60℃.The oxidation induction period of ABS graft copolymer prepared using sulfuric acid flocculant is longer than that prepared using magnesium sulfate flocculant.The addition temperature of antioxidant and the composition of flocculant have no effect on the mechanical properties of ABS resin,but have an obvious effect on its apparent properties such as whiteness and yellow index.关键词
