Abstract

The invention discloses stain and water resistant stone-like lacquer. The stone-like lacquer comprises, by weight, 10.0-12.0 parts of water, 12.0-14.0 parts of a silicone modified acrylic emulsion, 0.6-1.0 part of a film forming assistant, 0.3-0.6 part of ethylene glycol, 0.1-0.15 part of a pH regulator, 0.5-1.0 part of a hydrophobic agent, 0.05-0.1 part of an anticorrosive, 0.1-0.2 part of hydroxyethyl cellulose ether, and 70.0-75.0 parts of artificial sintered sand. Compared with the prior art, the film formed surface of the stain and water resistant stone-like lacquer has high hydrophobicity, and the stone-like lacquer has excellent water, acid and alkali resistance and low adhesion rate of dust particles. The stone-like lacquer cannot become white and loose after being washed by rainwater.

Description

technical field [0001] The invention relates to the technical field of building material coatings, in particular to a stain-resistant and water-resistant real stone paint. Background technique [0002] Real stone paint is a kind of thick paint with a decorative effect similar to granite and marble. It is mainly made of natural stone powder of various colors. my country introduced this material from the end of the last century and began to apply it to the decoration of interior and exterior walls of buildings. The buildings decorated with real stone paint have real and natural color, which can make people return to nature. [0003] In the existing technology, real stone paint is made of styrene acrylic emulsion and natural ore colored sand. This kind of real stone paint has a sand wall shape, and the coating film is rough after drying and forming a film. The surface of the coating film is dull and unclean; in order to increase the stability of the styrene acrylic emulsion,...
