Abstract

The invention provides a waterborne antistatic wear-resistant coating. The waterborne antistatic wear-resistant coating comprises 25-35% of water, 25-30% of waterborne resin, 0.7-2% of film-forming additives, 0.8-2.5% of dispersing agent, 0.3-1% of levelling agent, 0.1-0.2% of defoaming agent, 2-3.5% of waterborne adhesion promoter, 0.3-5% of titanium dioxide, 0-10% of talcum powder, 0-18% of nano calcium carbonate, 1-1.5% of pH regulator, 10-15.5% of silicon carbide and 6.5-10% of antistatic agent. The waterborne antistatic wear-resistant coating has the advantages of strong adhesion, good wear resistance, antistatic property, acid and alkali resistance, economical property and environment friendliness.

Description

technical field [0001] The invention relates to a water-based antistatic wear-resistant coating Background technique [0002] With the development of modern science and technology, there are more and more applications on walls and floors that require cleanliness and antistatic requirements, such as in electronic and electrical workshops, computer rooms, printing factories, textile factories, and pharmaceutical factories. Coatings are paid more and more attention to, and antistatic coating products are mainly made by adding antistatic agents or antistatic fillers to coatings. At present, there are also some water-based coatings on the market that have antistatic effect, but the application of coatings is limited due to problems such as unstable performance and wear resistance. [0003] The use of traditional solvent-based coatings is increasingly restricted due to their high levels of volatile organic compounds (VOCs) and harmful air pollutants. Therefore, pollution-free wa...
