一种受阻酚类聚丙烯复合型抗氧剂
摘要：
一种受阻酚类聚丙烯复合型抗氧剂，它由2～12重量份的主抗氧剂和1～5重量份的辅助抗氧剂复合而成：主抗氧剂按总质量100%计，N,N-双[3-(3,5-二叔丁基-4-羟基苯基)丙酰]己二胺的质量含量为2%～30%，α-维生素E的质量含量为N,N-双[3-(3,5-二叔丁基-4-羟基苯基)丙酰]己二胺的5%～75%，余量为四〔β-(3,5-二叔丁基-4-羟基苯基)丙酸〕季戊四醇酯。辅助抗氧剂为三(2,4-二叔丁基苯基)亚磷酸酯；该复合型抗氧剂的制备方法是先将N,N-双[3-(3,5-二叔丁基-4-羟基苯基)丙酰]己二胺、α-维生素E和四〔β-(3,5-二叔丁基-4-羟基苯基)丙酸〕季戊四醇酯混合，并颗粒化，然后与三(2,4-二叔丁基苯基)亚磷酸酯复合，并颗粒化，即得。本发明能更好地满足聚丙烯多方面综合性能的要求，可提高抗氧性能、降低成本。
摘要（英）：

The invention discloses a hindered phenol type polypropylene composite antioxidant which is formed by compounding the following components in parts by weight: 2-12 parts of a main antioxidant and 1-5 parts of an auxiliary antioxidant, wherein according to 100 percent of the main antioxidant, the mass percentage of N,N-di[3-(3,5-di-tert-butyl-4-hydroxy phenyl) propionyl] hexamethylene diamine is 2-30 percent; the mass content of alpha-vitamin E is 5-75 percent of N,N-di[3-(3,5-di-tert-butyl-4-hydroxy phenyl) propionyl] hexamethylene diamine, and the balance is tetra-{beta-(3,5-di-tert-butyl-4-hydroxy phenyl) propionic acid} pentaerythritol ester; the auxiliary antioxidant is tri(2,4-tert-butyl-phenyl) phosphite ester. The preparation method of the composite antioxidant comprises the steps of mixing N,N-di[3-(3,5-di-tert-butyl-4-hydroxy phenyl) propionyl] hexamethylene diamine, alpha-vitamin E and tetra-{beta-(3,5-di-tert-butyl-4-hydroxy phenyl) propionic acid} pentaerythritol ester to obtain a mixture, granulating the mixture, mixing the mixture with tri(2,4-tert-butyl-phenyl) phosphite ester to obtain another mixture, and granulating the second mixture to obtain the hindered phenol type polypropylene composite antioxidant. The hindered phenol type polypropylene composite antioxidant can better meet the requirement for the multi-aspect comprehensiveness of polypropylene, and the antioxidant performance can be improved, and the cost is lowered.
