Problems solved by technology

[0003] As one of the substitutes, although the imitation granite real stone paint is somewhat similar in decorative effect and has good product performance, it is currently used to prepare water-in-water multi-color paint for the preparation of imitation granite. Its disadvantages are 1. The granulation process is complicated. ; 2. Because the colorful particles are wrapped in a liquid state, their storage stability is poor; 3. There are many hydrophilic substances in the formula system, and the coating film is easy to whiten when exposed to water; 4. The storage environment of the finished paint is high, and the finished paint The color particles in it are easy to mix and paste, and cannot be stirred or diluted; 5. The drying speed is slow, and the thunderstorm weather in winter and summer has a greater impact; 6. Special vacuum pressure spraying tools are required, which is difficult to spray and easy to sag. 7. The colored dots in the imitation stone finish coating are mostly round dots, without natural texture, unlike the crystals in stone, which are polygonal and broken; 8. Although the water-in-water products are gorgeous, their production and construction are limited. External and human factors are relatively large, so "too delicate"

Abstract

The invention discloses granite look-alike texture paint and a preparation method of simulative granite. The granite look-alike texture paint comprises 40wt% of texture species and 60wt% of a liquid colorful base material. The preparation method comprises the following steps of primer coating, texture specie and liquid colorful base material preparation, texture paint compounding, and texture paint spray-coating. The texture species are solids and have good stability; the compound granite look-alike texture paint has good water resistance and does not change in water in 96h; in preparation of the simulative granite, a drying rate after spray-coating is fast so that the weather effect is reduced in construction; and the granite look-alike texture paint has the advantages of no sagging, no flooding, good elasticity and cracking resistance.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, in particular to a granite-imitation pattern paint and a preparation method of imitation granite. Background technique [0002] Due to its excellent durability and excellent decorative and protective effects, natural granite is widely used in high-end exterior wall decoration projects. However, as a brittle material, natural stone has poor material uniformity and large dispersion of bending strength. During the process of generation, mining and processing, it is inevitable that there will be some slight internal injuries that are not easy to find. Although the stone in the curtain wall does not bear the load of the three-dimensional structure, it must bear the influence of loads and effects such as self-weight, wind, earthquake, wall deformation and temperature. Therefore, even if the stone used meets the requirements of the national product standards, it is still unavoidab...
