一种环氧树脂涂料及其制备方法
摘要：
本发明提供一种环氧树脂涂料，包括树脂组分和固化剂组分，树脂组分包括：25wt％～40wt％的环氧当量为235～265的环氧树脂，3wt％～6.5wt％的环氧当量为170～195的环氧树脂，0.2wt％～0.7wt％的分散剂，1wt％～2wt％的流平剂，5wt％～12wt％的稀释剂和50wt％～65wt％填料；固化剂组分包括：18wt％～26wt％的酚醛胺改性固化剂，52wt％～66wt％的腰果油改性酚醛胺固化剂，10wt％～25wt％的二甲苯；环氧树脂组分与固化剂组分的重量比为6～7∶1。本发明还提供一种制备上述环氧涂料的方法。本发明提供的环氧树脂涂料无毒，可用于与食品直接接触的管道和设备。
摘要（英）：

The invention provides an epoxy resin coating, which consists of resin components and curing agent components; the resin components include 25 to 40 percent by weight of epoxy resin with the epoxy equivalent weight of 235 to 265, 3 to 6.5 percent by weight of epoxy resin with the epoxy equivalent weight of 170 to 195, 0.2 to 0.7 percent by weight of dispersant, 1 to 2 percent by weight of levelling agent, 5 to 12 percent by weight of diluent and 50 to 65 percent by weight of filling; the curing agent components include 18 to 26 percent by weight of phenolic aldehyde amine modified curing agent, 52 to 66 percent by weight of cashew nut oil modified phenolic aldehyde amine curing agent and 10 to 25 percent by weight of dimethylbenzene; and the weight ratio of the resin components to the curing agent components is 6 to 7:1. The invention also provides a method for preparing the epoxy resin coating. The provided epoxy resin coating is non-toxic, and can be used on conduits and equipment which are directly contacted with food.
