Problems solved by technology

[0002] With the development and progress of buildings, the development of architectural coatings is also changing with each passing day, and their applications are becoming more and more extensive. However, outdoor coatings are always polluted by the external environment in their use environment. After a period of use, due to the continuous accumulation of pollutants, the paint gradually loses its color. color, and in the process of use, the coating film is easily damaged by external scratches, therefore, the research and development of the antifouling performance and anti-scratch performance of the coating has received more and more attention. Therefore, the present invention aims to Develop a new water-based anti-fouling and wear-resistant coating to better meet actual needs

Abstract

The invention relates to a water-based antifouling wear-resistant coating. The coating is prepared from the following raw materials in parts by weight: 30 to 40 parts of a styrene-acrylic emulsion, 20to 40 parts of water, 10 to 20 parts of lithopone, 5 to 8 parts of heavy calcium carbonate, 3 to 5 parts of epoxypropane, 5 to 10 parts of chitosan, 1.2 to 1.6 parts of a coalescing agent, 0.5 to 0.8part of a thickening agent, 0.1 to 0.2 part of a defoaming agent and 0.05 to 0.1 part of a preservative. Through the interaction of the components, the coating has good scratch-repairing, water-resistant and oil-resistant effects.
