Abstract

The invention discloses a waterborne UV (ultraviolet) antifouling self-cleaning coating which comprises the following components in parts by weight: 100 parts of coating components and 3-10 parts of aid components, wherein the coating components comprise the following components in parts by weight: 40-60 parts of a waterborne polyurethane acrylate emulsion, 5-10 parts of a waterborne UV monomer, 5-10 parts of wax powder, 2-5 parts of a light initiator, 0.05-0.2 part of a pH regulator, 0.5-2 parts of a wetting agent, 0.1-0.5 part of a defoaming agent, 0.1-0.4 part of a dispersant, 0.5-2 parts of a rheological agent and 3-6 parts of matting powder and 20-30 parts of deionized water; the aid component comprises the following components in parts by weight: 70-90% of trifluorooctyl triethoxysilane and 10-30% of a diluent. The coating is good in base material wettability, good in leveling performance, low in surface tension, smooth in paint film, delicate and smooth in hand feeling, good inadhesion, good in water boiling resistance, good in weather resistance and good in wear resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a water-based UV anti-fouling self-cleaning coating and its preparation method and application. Background technique [0002] With the development of science and technology and the improvement of living standards, mobile consumer goods such as mobile phones and computers have become an indispensable part of people's daily life. However, these mobile consumer products are easily stained with other pollutants such as oil stains and hand sweat during use, which affects the appearance. The pollution of mobile consumer products is often improved by spraying paint on the plastic surface of mobile consumer products. [0003] At present, water-based coatings are often sprayed. Water-based coatings only use a small amount of low-toxic alcohol ether organic solvents as co-solvents, which improves the construction environment, reduces VOC emissions, eliminates fire hazards during construc...
