Abstract

The invention relates to a water-based coating and a preparation method thereof. The water-based coating is prepared from the following raw materials in parts by weight: 20-50 parts of a high polymermaterial water-based dispersion body, 10-30 parts of water, 3-5 parts of nano SiO2 powder, 4-6 parts of nano silver dioxide powder, 1-3 parts of a leveling agent and 2-4 parts of an antifoaming agent.The invention provides the water-based coating and the preparation method thereof, and overcomes the defects that a conventional water-based material is not environment-friendly, poor in antibacterial effect and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based coating and a preparation method thereof. Background technique [0002] Water-based coatings are coatings that use water as a dispersion medium and thinner. Compared with organic solvent-based coatings, water-based coatings not only reduce the emission of volatile organic solvents, but also save resources and energy (energy consumption is required to produce solvents), and are convenient. Transport and storage. With the enhancement of people's awareness of environmental protection, the relevant environmental protection regulations on the production and use of chemical products are becoming more and more stringent, so water-based coatings have become the mainstream direction of the development of modern coatings industry. [0003] Thin boards are often used in home appliances, and the surface is easily polluted, adhered to water and oil stains during use, which pro...
