Abstract

The invention discloses a liquid aqueous multi-color granite coating and a preparation method thereof, for solving the problems that a conventional aqueous granite coating is severely thickened after a multi-color coating is stored, and is large in viscosity and has easily damaged constructed multi-color particles. The liquid aqueous multi-color granite coating is prepared from the following raw materials in parts by weight: 23.0-27.0 parts of silicone acrylic emulsion, 1.0-2.0 parts of propylene glycol, 1.0-2.0 parts of filming agent, 0.1-0.3 part of defoaming agent, 8.0-14.8 parts of water, 0.1-0.3 part of preservative, 0.1-0.3 part of thickening agent and 58.0-62.0 parts of multi-color particles. According to the coating, multi-color paint protecting glue is used together with special resins, elastic emulsion and silicone acrylic emulsion special for multi-color paint, the reaction gel degrees of different components are controlled to achieve relative balance of a system, the coating is free of color bleeding phenomenon after being stored for a long time and is clear and definite in color particle after being sprayed, the later thickening phenomenon of the stored liquid aqueous multi-color granite coating is effectively solved, and the storage and construction stability is improved.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, in particular to a liquid water-based colorful granite coating and a preparation method thereof. Background technique [0002] At present, most of the water-based granite paints on the market are mostly made of a kind of protective glue. After storage, the color particles bleed, and the thickening of the colorful paint is serious, the viscosity is high, and the color particles are easy to be damaged. At the same time, water-based granite coatings have poor water resistance and insufficient anti-fouling ability. When used on outdoor walls, the surface is easily contaminated with dust and dirt, and manual cleaning is difficult. Contents of the invention [0003] The purpose of the present invention is to provide a liquid water-based colorful granite coating with good stability and high degree of simulation and its preparation method, so as to solve the problems of existing water-ba...
