A hydrophobic and scale-inhibiting hot-melt powder coating, coating material and its preparation method

By combining modified phenolic epoxy resin and mica powder with electrostatic spraying, a hydrophobic and scale-inhibiting thermally fused powder coating with excellent performance under high temperature and high pressure conditions was prepared. This solved the problems of poor wear resistance and decreased hydrophobicity of existing coatings, and achieved long-lasting anti-corrosion and scale inhibition effects.

Abstract

This invention provides a hydrophobic and scale-inhibiting hot-melt powder coating, a coating layer, and a method for preparing the same. The raw materials for preparing the hydrophobic and scale-inhibiting hot-melt powder coating include, by weight, 50-70 parts epoxy resin, 30-50 parts modified phenolic epoxy resin, 15-25 parts curing agent, 0.5-1.5 parts accelerator, 1.5-3 parts leveling agent, 0.5-1 part degassing agent, 1-2 parts powder flow aid, 30-40 parts modified composite filler, 1-2 parts pigment, and 0.5-2 parts wax powder; the modified phenolic epoxy resin is a fluoropolymer-modified phenolic epoxy resin; the modified composite filler includes modified mica powder, wollastonite powder, barium sulfate powder, and talc powder. The coating obtained by the coating provided by this invention has strong adhesion to the substrate, high adhesion, and excellent hydrophobic properties, scale inhibition and antifouling properties, impact resistance, wear resistance, and chemical corrosion resistance, and can maintain stable chemical properties for a long time.
