一种厚膜环氧煤沥青防腐蚀涂料及制造方法
摘要：
本发明涉及一种厚膜环氧煤沥青防腐蚀涂料及制造方法，用中等分子量双酚A型环氧树脂加入二甲苯、正丁醇、丁酮、煤沥青树脂液、增韧树脂、沉淀硫酸钡、绢云母粉、滑石粉、蹄合型流变控制助剂，偶联剂201、CibaEFKA3650助剂、有机硅消泡剂和聚有机羧酸盐，经搅拌、高速分散、研磨制成A组分；酚醛胺、促进剂、乙醇和CibaTINUVIN460光稳定剂搅拌制成B组分，两者按A∶B＝10∶1混合均匀后使用；是一种具有一定韧性的环氧煤沥青防腐蚀涂料，该涂料用于PCCP外壁防腐具有附着力优异、抗微生物腐蚀性好、施工使用期长，并具有一定的抵抗光老化性能。
摘要（英）：

The invention relates to a high-build epoxy coal tar pitch anticorrosive coating and a preparation method thereof. The preparation method comprises the following steps of: adding dimethylbenzene, n-butyl alcohol, butanone, coal tar pitch resin liquid, toughened resin, precipitated barium sulfate, silk mica powder, talc powder, a hoof-joint type rheological control aid, a coupling agent 01, a CibaEFKA3650 aid, an organic defoaming agent and poly organic carboxylate into bisphenol A type epoxy resin with medium molecular weight, stirring, dispersing at a high speed, and grinding into a component A; stirring phenolic ammonia, an accelerator, ethanol and a CibaTINUVIN 460 light stabilizer to form a component B; and uniformly mixing the component A and the component B in a ratio of 10:1. The high-build epoxy coal tar pitch anticorrosive coating has certain toughness, and has excellent adhesion, high microbial corrosion resistance, long construction operating period and certain light ageing resistance when applied to prestressed concrete cylinder pipe (PCCP) exterior walls.
