Problems solved by technology

[0003] Real stone paint is used as the wall of buildings. Most of the existing products focus on protection and decoration functions, which leads to the fact that real stone paint is prone to cracks during film formation and use, and its aging resistance is not good, and it is prone to peeling. With the improvement of people's living standards, the existing real stone paint can no longer meet people's needs.

Abstract

The invention discloses an anti-aging texture stone-like paint. The stone-like paint comprises the following raw materials in parts by weight: 30 to 40 parts of quartz sand, 18 to 25 parts of coloredsand, 7 to 12 parts of modified styrene-acrylic emulsion, 6 to 10 parts of SiO2 aerogel powder, 4 to 6 parts of a thickening agent, 1 to 2 parts of butyl cellosolve, 0.2 to 0.3 part of methyl alcohol,1 to 2 parts of a wetting agent, 1 to 2 parts of a defoaming agent, 0.5 to 1 part of chitin and 0.1 to 0.2 part of a water repellent. The stone-like paint disclosed by the invention has preferable anti-aging performance, and simultaneously is high in cracking resistance, heat stability, heat insulation and mechanical property.

Description

technical field [0001] The invention relates to real stone paint, in particular to an aging-resistant real stone paint. Background technique [0002] Real stone paint is a kind of paint with a decorative effect similar to marble and granite. The coating of real stone paint is composed of primer layer, real stone paint layer and finish paint layer. The primer layer adopts a primer with anti-alkali sealing effect, which can isolate and prevent moisture from penetrating into the coating from the base concrete, strengthen the adhesion between the coating and the base surface, and avoid peeling off of the coating; The three-dimensional main body material plays various protective functions. The overcoat is a decorative protective layer, which can not only strengthen the waterproof function of the real stone paint layer, but also improve the weather resistance and pollution resistance of the coating, enhance the hardness of the coating film, and make the coating surface more glos...
