High-performance real-stone-like paint and preparation method thereof

Abstract

The invention discloses a high-performance real-stone-like paint and a preparation method thereof. The high-performance real-stone-like paint comprises, by weight, 100 parts of water, 80-120 parts ofa cellulose dispersant, 58-60 parts of white sand, 3-10 parts of natural color sand a, 10-12 parts of natural color sand b, 2-4 parts of a bactericide, 3-20 parts of ethylene glycol, 3-8 parts of an antifoaming agent, 5-17 parts of a film forming aid2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 150-200 parts of an emulsion, 2-5 parts of a thickener RM-8W and 30-40 parts of silica sol. Accordingto the invention, since the thickener RM-8W is utilized, thickening efficiency is improved, and the water resistance, stain resistance and adhesion performance of the real-stone-like paint are greatly enhanced; at the same time, the 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate film forming aid is employed to control the film formation time of the real-stone-like paint, so the drying time of real-stone-like paint is made controllable; and the natural color sand a with a size of 40-80 meshes and the natural color sand b with a size of 80-120 meshes are matched according to a reasonable ratio, so the water resistance, stain resistance and adhesion performance of the real-stone-like paint are further improved, and the problems of proneness to floating and whitening and poor adhesion duringconstruction at low temperature and high humidity and construction at low temperature and low humidity are overcome, and thus, the comprehensive performance of the real-stone-like paint is greatly optimized.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-performance real stone paint and a preparation method thereof. Background technique [0002] Coating is a building material with a long history. With the development of society, there are more and more types of coatings. According to reports, indoor coatings are mainly divided into two types: water-based coatings and solvent-based coatings. The main source of pollution is solvent-based paint, and the use of environmentally friendly water-based paint can completely eliminate the worry about paint pollution. Experts from the China Paint Industry Association believe that any solvent-based paint will contain 50% or more of organic solvents. Since most solvent-based paints and organic solvents contain benzene and its compounds, long-term exposure will cause serious harm to the human body. Therefore, more and more people like to choose environmentally friendly and non-toxic water-based...

Problems solved by technology

[0004] However, most of the current real stone paints often have many problems in construction and application, especially under the conditions of low temperature and high humidity and low temperature and low humidity, the coating is often not resistant to water, and it will bloom when it encounters water. White, fading, poor adhesion, poor antibacterial performance, seriously affect the quality and decorative effect of real stone paint
