Abstract

An impact-resistant chemical adhesive wear-resistant coating with a flame retardant function consists of component A and curing agent component B. The component A includes 10-40 parts of nano-silica aerogel, 10-40 parts of nano-alumina solution, 5-10 parts of aramid pulp, 40-60 parts of bisphenol A epoxy resin, 300-400 parts of silicon carbide and 1-5 parts of a dispersant. The curing agent component B includes 5-15 parts of polyamine, 1-5 parts of polythiol, 0-5 parts of silane coupling agent and 0.5-5 parts of silica. During use, the ratio of the component A and the curing agent component Bis 10:1. The method includes firstly mixing a nano photocatalyst with a first solvent and then adding polyvinylidene fluoride to improve the stability of nanoparticles and polyvinylidene fluoride.

Description

technical field [0001] The invention relates to the field of materials, in particular to a chemical adhesive and wear-resistant coating with impact resistance and flame-retardant function. Background technique [0002] In the washing equipment and piping system of mines, smelting, power plants, etc., the erosion and abrasive wear of the equipment and the inner wall of the pipeline caused by the slurry are very serious. The use of lining ceramic sheets and polyurethane coatings is a common wear-resistant protection method; however, the method of lining ceramic sheets, because the inner walls of equipment and pipelines are mostly curved, ceramic sheets are difficult to mount tightly, and are easy to cause damage under the impact of ore. Spraying polyurethane coating cannot form a thicker coating, and it is difficult to resist the impact and abrasive wear of heavy-duty ore; and both are difficult to quickly repair the damaged part on site. [0003] For the on-site repair and p...
