Abstract

The invention relates to special modified solvent-free epoxy paint glass reinforced plastic, which is prepared by mixing component A with component B proportionally. The component A comprises following raw materials which include, by weight, 50-65 parts of epoxy resin, 3-5 parts of reactive diluents, 3.5 parts of anti-settling agent, 0.5 part of dispersing agent, 0.5 part of flatting agent, 0.5 part of antifoaming agent, one part of silane coupling agent, 5 parts of mica powder, 10 parts of high-gloss barium and 5 parts of special preservative. The component B comprises 10 parts of modified amine hardener by weight. The special modified solvent-free epoxy paint glass reinforced plastic is composed of the component A and the component B which are mixed by proportion and can react and be solidified quickly when the paint is used, has excellent adhesion stress, tightness and mechanical property on metal or nonmetal substrates, fine corrosion resistance and high cathode stripping resistance, and is high in compression, compact and shearing resistance. Furthermore, the special modified solvent-free epoxy paint glass reinforced plastic is free of solvent and high in solid proportion, and belongs to nontoxic and environment-friendly paint.

Description

technical field [0001] The invention relates to a paint, in particular to a special modified solvent-free epoxy paint for FRP. Background technique [0002] Fiberglass reinforced plastics (FRP), also known as GRP, are fiber reinforced plastics, generally referring to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics made of glass fiber or its products are called glass fiber reinforced plastics, or FRP. Due to the different types of resin used, it is called polyester FRP, epoxy FRP, and phenolic FRP. Lightweight and hard, non-conductive, high mechanical strength, less recycling, corrosion resistance. It can replace steel to manufacture machine parts, automobiles, ship shells, etc. However, the existing anti-corrosion coatings for FRP have poor anti-corrosion performance and a small scope of application. Contents of the invention [0003] The technical problem to be solved by the present invention is to develop an an...
