Thermo-sensitive epoxy resin powder paint

热敏性环氧树脂粉末涂料

Abstract

The thermosensitive epoxy resin powder paint consists of low softening point epoxy resin 60-70 wt%, curing agent 3-6 wt%, photoinitiator 0.5-1.0 wt%, leveling agent 1-2 wt%, defoaming agent 0.5-1.0 wt%, and pigment and stuffing 20-35 wt%. The present invention has imidazole type low temperature curing agent resulting in low temperature fast curing and photoinitiator to further raise low temperature curing speed, so that the paint has high low temperature curing speed. The present invention has short production period, low power consumption, low production cost and high production efficiency.
一种热敏性环氧树脂粉末涂料,包括环氧树脂、固化剂、光引发剂、消泡剂、颜料和填料,低软化点环氧树脂为60~70%重量,固化剂为3~6%重量,光引发剂为0.5~1.0%重量,流平剂为1~2%重量,消泡剂为0.5~1.0%重量,颜料和填料为20~35%重量。本发明采用咪唑型的低温固化剂、光引发剂和流平剂与低软化温度即低熔融温度的环氧树脂相互作用,咪唑型低温固化剂的分子结构中具有低活化能反应基团,具低温快速固化特性能。光引发剂的加入提高了低温固化速度,缩短固化时间。综合效果是降低固化温度,提高固化速度,固化温度从原来的180℃~200℃/20~30min降低到120℃~130℃/16min。缩短生产周期,节省能源,降低生产成本,提高生产效率。
