Problems solved by technology

Traditional real stone paint uses cellulose-based thickeners. A large number of hydroxyl functional groups on the surface of the thickener greatly reduce the water and antifouling performance and water resistance of real stone paint (Guo Qingquan, Li Yongjin, Chen Huanqin. Stain resistance and Influencing factors[J]. Green Building, 2003, 19(5):15-18.), making the surface of real stone paint easily polluted and easy to fall off from the outer wall cavity in a humid environment

Abstract

The invention relates to the technical field of coatings, in particular to a high-performance water-resistant antifouling stone-like coating. The traditional stone-like coating adopts a cellulose thickener, and a large number of hydroxyl functional groups on the surface of the thickener greatly reduce the water resistance, antifouling property and water resistance of the stone-like coating. In order to solve the problem, the invention provides the high-performance water-resistant antifouling stone-like coating, An added coalescing agent is a compound of diethylene glycol monomethyl ether and diethylene glycol butyl ether acetate, and the mass ratio of the diethylene glycol monobutyl ether to the diethylene glycol butyl ether acetate is 1: (1-2); an added multifunctional auxiliary agent isa mixture of 2-butylaminoethanol and 2-N-dibutylaminoethanol, and the mass ratio of the 2-butylaminoethanol to the 2-N-dibutylaminoethanol is 1: 1.5. Compared with the traditional stone-like coating,the high-performance water-resistant antifouling stone-like coating prepared by the method has better antifouling and water-resistant properties.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-performance water-resistant and anti-fouling real stone paint. Background technique [0002] At present, in order to achieve the effect of natural stone materials in buildings, natural stone materials are commonly used, but natural stone materials are limited by natural ore, and the color and pattern after decoration are not uniform, and they cannot be refurbished. It is difficult to mine and process, and the price is expensive; The load on the wall is heavy, so it is not suitable for the decoration of light buildings. In addition, the construction is difficult, especially the corners need special processing, the gaps between the stones need to be filled with sealant, and the overall waxing is required after the construction is completed. [0003] The spraying effect of real stone paint is solemn and elegant, which can fully show the rich texture of natural stone. The use...
