防腐涂料及其制备方法和应用
摘要：
本发明公开了一种防腐涂料，其包括重量比为2～7:1的A组分与B组分；A组分包括有机硅改性环氧树脂20～50重量份，防锈颜料5～35重量份，添加剂15～40重量份，溶剂A 5～25重量份，润湿分散剂0.1～1重量份，消泡剂0.1～1重量份，流平剂0.2～1.5重量份和防沉剂0.2～1.5重量份；B组分包括腰果酚改性酚醛胺固化剂65～90重量份，固化促进剂2～20重量份和溶剂B 2～15重量份。该防腐涂料在经过高温、强酸或强碱腐蚀后仍具有较高的附着力。本发明还公开了该防腐涂料的制备方法以及该防腐涂料在钢桥面上的应用。
摘要（英）：

The invention discloses an anticorrosive paint, which comprises a component A and a component B in a weight ratio of 2-7:1. The component A comprises: 20-50 weight parts of organosilicon modified epoxy resin, 5-35 weight parts of antirust pigment, 15-40 weight parts of an additive, 5-25 weight parts of a solvent A, 0.1-1 weight part of a wetting dispersant, 0.1-1 weight part of a defoamer, 0.2-1.5weight parts of a levelling agent and 0.2-1.5 weight parts of an anti-settling agent; and the component B comprises: 65-90 weight parts of a phenolic aldehyde amine curing agent, 2-20 weight parts ofa curing accelerator and 2-15 weight parts of a solvent B. The anticorrosive paint still has high adhesion after enduring high temperature, strong acid or strong alkali corrosion. The invention alsodiscloses a preparation method of the anticorrosive paint and application of the anticorrosive paint on steel bridge surfaces.
