Abstract

The invention relates to an environment-friendly type modified fluorocarbon exterior wall coating and a preparation method thereof. The environment-friendly type modified fluorocarbon exterior wall coating comprises perfluorocarbon emulsion, a dispersing agent, a coalescing agent, a flatting agent, a thickening agent, bactericide, an antifoaming agent, a PH modifier, a coupling agent, deionized water and the like. The environment-friendly type modified fluorocarbon exterior wall coating has the advantages of being high in activity, good in stability, non-toxic, environmentally friendly, low in price and the like. The environment-friendly type modified fluorocarbon exterior wall coating is superior to a water-based fluorocarbon coating in the aspects of water resistance, alkali resistance, rubbing resistance, artificial aging resistance, high temperature resistance, oil resistance and other common performance. The environment-friendly type modified fluorocarbon exterior wall coating is suitable for building coating.

Description

technical field [0001] The invention relates to a paint, in particular to an environment-friendly architectural paint. Background technique [0002] In recent years, under the circumstances that the use of glass curtain walls and decorative bricks in high-rise buildings is gradually restricted in various regions of the country, exterior wall coatings are gradually becoming the main material for architectural decoration. Among them, fluorocarbon coatings have comprehensive advantages unmatched by other coatings in terms of weather resistance, corrosion resistance, chemical resistance, and stain resistance, and are gradually favored by people. However, cracks are common in fluorocarbon building exterior wall coatings during construction. Moreover, with the continuous improvement of people's quality of life, higher requirements are placed on the performance of fluorocarbon exterior wall coatings, among which weather resistance, high temperature resistance, and oil resistance a...
