Problems solved by technology

[0002] Due to the advantages of no pollution, resource saving and high efficiency, powder coatings have entered a high-speed development stage, and the application fields have been greatly expanded. In daily life, some furniture and household appliances are prone to scratches, so the demand for wear-resistant powder coatings is increasing day by day. When the coating is heated and melted to knead the resin and curing agent, due to the uneven dispersion of the curing agent, the advection is poor, so the appearance of the coating film is not good. In addition, the dispersion of the pigment and the filler is poor, and the liquid Compared with paint, it is difficult to obtain bright, clear and glossy coating film with powder coating

Abstract

The invention relates to the technical field of coating materials, particularly to a domestic wear-resistant coating material, which comprises, by mass, 30-50 parts of a medium oil length non-dry modified alkyd resin, 2-6 parts of a curing agent, 15-20 parts of a colorant, 1-8 parts of a leveling agent, 1-6 parts of benzoin, 15-20 parts of barium sulfate, 1-5 parts of a loosening agent, and 1-5 parts of an anti-caking agent. According to the present invention, during the melting, the domestic wear-resistant coating material migrates to the surface to form a protection layer so as to reduce thesurface tension and the surface friction coefficient of the coating film, such that the wear resistance is improved; and the experiment results show that per g of the coating film only has the weightloss of 0.022 g while the hardness reaches 3H.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a household wear-resistant coating. Background technique [0002] Powder coatings have entered a stage of rapid development due to their non-polluting, resource-saving and high-efficiency advantages. The application fields have expanded greatly. In daily life, some furniture and appliances are prone to scratches. Therefore, the demand for wear-resistant powder coatings is increasing. When the coating is heated and melt-kneaded the resin and curing agent, due to the uneven dispersion of the curing agent and poor advection, the appearance of the coating film is not good, and the dispersibility of pigments and fillers is poor. Compared with coatings, powder coatings are difficult to obtain bright, clear and glossy coating films. Summary of the invention [0003] In order to overcome the shortcomings of the existing powder coatings, the present invention provides a household wear-resista...
