Wear-resisting epoxy paint

Abstract

The invention belongs to the technical field of macromolecules, and particularly relates to wear-resisting epoxy resin which can be used for repairing equipment and pipelines. The paint comprises a component A and a component B, and is characterized in that the component A comprises the following raw materials in parts by weight: 20 to 45 parts of mixed epoxy resin, 2 to 8 parts of diluent, 1 to 4 parts of silane coupling agent, 10 to 30 parts of iron-base alloy powder, 10 to 30 parts of aluminum oxide powder, 5 to 20 parts of silicon carbide, 10 to 20 parts of ceramic powder, 1 to 4 parts of glass flakes and 1 to 4 parts of carbon black; the component B comprises the following raw materials in parts by weight: 70 to 80 parts of high-hardness wear-resisting epoxy curing agent and 20 to 30 parts of epoxy promoter. The adhesion force of the wear-resisting epoxy resin on a base material can be improved by adopting the mixed epoxy resin; the wear resistance and the medium resistance of the epoxy paint are improved by adopting p-aminophenol glycidyl amine (ether) trifunctional epoxy resin; the wear resistance of the epoxy resin can be improved by adding the wear-resisting filler such as the iron-base alloy powder and the silicon carbide.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and in particular relates to a wear-resistant epoxy paint which can be used for repairing equipment and pipelines. Background technique [0002] Epoxy resin coatings are widely used, with low shrinkage, high bonding strength, easy preparation, simple process, high hardness of cured products, easy modification, and good adhesion to various metals and most non-metallic materials. [0003] Two-phase fluid erosion is one of the important reasons for equipment and pipeline damage and scrapping. At present, the types of wear-resistant materials used at home and abroad include alloy materials, inorganic materials (such as silicon carbide, high alumina ceramics, etc.), organic materials (such as polyurethane , nylon, rubber, etc.). Alloy materials have high temperature and wear resistance, but they have high density, complex molding, high cost, and difficult on-site construction; although inorgan...

AI Technical Summary

Problems solved by technology

The existing epoxy-based wear-resistant coatings generally add friction-reducing materials such as graphite and molybdenum disulfide and hard materials such as oxides, iron powder, and aluminum powder to the epoxy resin coating. The epoxy resin coating formed in this way is insufficient Designed to resist very harsh wear conditions and environments
