摘要
本文研究了四种抗氧剂在双组份聚氨酯涂料中的作用效果。实验表明:(1)抗氧剂适宜在预聚物合成初始加入;(2)抗氧剂264在本实验体系中抗氧效果优于其它三种;(3)SP+TNP具有协同效应。
In this paper, we study the effectiveness of action that four kinds of antioxidants are added in the polyurethane coating. The experiment result indicate: (1)The antio- xidants are put into prepolymer on the initial stage of prepolymerization. (2)The antioxidant--264 is better than another three in the system. (3)The SP+TNP are sho- wed cooperative effect.
