Abstract

The invention discloses a bi-component epoxy resin composite wear-resistant coating and belongs to the technical field of high polymer materials. The preparation method comprises the following steps:sequentially weighing the following components in parts by weight: 50-80 parts of epoxy resin, 3-6 parts of a flatting agent, 3-6 parts of a dispersing agent, 15-22 parts of a wear-resistant modifierand 60-100 parts of a solvent, mixing the epoxy resin and the solvent into a stirrer, and adding the flatting agent, the dispersing agent and the wear-resistant modifier into the stirrer, and stirringand mixing at the temperature of 30-60 DEG C under the rotating speed of 300-320 r / min to obtain a component a; sequentially weighing the following components in parts by weight: 10-15 parts of a curing agent and 20-22 parts of a solvent, stirring and mixing the curing agent with the solvent to obtain a component b; and separately packaging the component a and the component b to obtain the bi-component epoxy resin composite wear-resistant coating. The bi-component epoxy resin composite wear-resistant coating prepared by the technical scheme disclosed by the invention has the characteristics of excellent wear resistance and wide prospect in the development of the polymer material technical industry.

Description

technical field [0001] The invention discloses a two-component epoxy resin composite wear-resistant paint, which belongs to the technical field of polymer materials. Background technique [0002] Epoxy resin has excellent adhesion and mechanical strength, and is widely used as a coating material. However, due to its dense aromatic structure after curing, high crosslinking density and high cohesion, the cured product has poor deformation ability and is often in a brittle state. The wear-resistant coating prepared with it often cannot meet the performance requirements. How to improve the toughness of the epoxy resin matrix and further improve the wear resistance of wear-resistant coatings, some scholars have carried out a lot of research work on this, mainly including: elastomer toughening, thermoplastic resin toughening and expansion monomer copolymerization modification permanent epoxy resin. The coating film formed by epoxy resin coating not only has a shielding effect on...
