摘要
固化剂的种类对环氧导静电涂料的各项性能影响很大,因此,固化剂的选择尤为重要。对酚醛胺T31、聚酰胺650两种固化剂进行比较试验,并对涂膜的力学性能(漆膜干燥时间、抗冲击强度、附着力、柔韧性)、导静电性能、耐油性能进行研究。结果表明:与聚酰胺650相比,酚醛胺T31配制的环氧导静电涂料具有优良的力学性能和耐油性能,且表面电阻率为108Ω,而聚酰胺650配制的涂料表面电阻率为1011Ω。因此,酚醛胺T31是环氧导静电涂料的最佳固化剂。
It is very important to choose the curing agent in coatings, the type of curing agents has considerable influence on diversified properties of coating. The two curing agents ( phenolic aldehyde amine T31 and polyimide 650 ) were compared. The influence of curing agents on the properties of coating, such as mechanics capability ( drying time , ash strength, adhesion and flexility, static conductivity capability and oil-resistant capability were also studied. It was found that T31 as curing agents for coating has outstanding mechanics capability and oil-resistant capability and surface resistance rate is 10^8Ω , whereas 650 is 10^11Ω. So T31 is optimal curing agents for the epoxy static electricity conductive coating.
