Optical self-cleaning granite-like paint and preparation method thereof

Abstract

The invention relates to optical self-cleaning granite-like paint and a preparation method thereof. The paint is prepared from the following components in percentage by weight: 60-74 percent of natural colored sands, 10-20 percent of polymer emulsion, 8-12 percent of nano-titanium dioxide, 0.2-0.5 percent of hydroxyethyl cellulose, 0.3-0.5 percent of bactericide, 0.5-1.0 percent of an antifreezing agent, 1-2 percent of auxiliary and 6-14 percent of water. Anatase nano-titanium dioxide is applied to manufacture of granite-like paint, so that the granite-like paint has an excellent granite imitation effect, and has the effect which is basically the same as that of existing granite-like paint; the granite-like paint has an excellent fouling resistance, and the fouling resistance of a wall surface can be effectively improved.

Description

technical field [0001] The invention relates to the field of coatings for exterior wall decoration, in particular to a light-energy self-cleaning real stone paint and a preparation method thereof. Background technique [0002] Real stone paint, also known as imitation stone paint, colored glaze quartz sand paint, the construction industry standard is called synthetic resin emulsion sand wall architectural paint, which is based on synthetic resin emulsion and natural colored sand with different particle sizes as aggregate. Thick architectural coatings prepared with various additives. Compared with traditional pasted tiles and dry-hanging stone materials, real stone paint is favored by more and more people because of its obvious advantages such as convenient construction, low cost, safety and non-toxicity, natural and generous, durable, and the decorative effect is closest to stone materials. . Among them, colored sand real stone paint has been highly concerned by the indust...

AI Technical Summary

Problems solved by technology

[0003] However, real stone paint is limited to its own formula problem, and its stain resistance problem has been the biggest problem of real stone paint for many years, and it is also a very difficult problem in the industry

After the real stone paint is painted, it will inevitably be stained with some dust, dirt, etc. under natural conditions, which will affect its overall aesthetic effect.

[0004] Chinese invention patent application CN 105060775 A discloses a real stone paint and its preparation method, which is mixed with emulsion, ethyl silicate, zirconium silicate, nano-titanium dioxide, natural coarse colored sand, natural fine colored sand and rock flakes of various colors. The hydrolysis of ethyl silicate results in ortho silicic acid, which reacts with zirconium silicate, but ethyl silicate is insoluble in water at room temperature, so it is difficult to carry out the hydrolysis reaction, and the market price of ethyl silicate is relatively high
