Wear-resistant, heat insulation and waterproof building coating and preparation method thereof

Abstract

The invention discloses a wear-resistant, heat insulation and waterproof building coating. The wear-resistant, heat insulation and waterproof building coating is characterized by being prepared from the following raw materials in parts by weight: 33-36 parts of water-soluble alkyd resin, 33-36 parts of an organic silicone resin emulsion, 1-2 parts of 1, 2-benzisothiazolin-3-one, 0.4-0.8 part of hydroxyethyl cellulose, 1-2 parts of sodium aluminosilicate, 1-3 parts of tert-butyl methacrylate, 0.5-1.0 part of fumed silica powder, 2-3 parts of silicon carbide powder, 1-3 parts of clay, 1-2 parts of dibutyl phthalate, 0.3-0.4 part of an organic silicon defoamer, 0.3-0.6 part of polyoxyethylene lauryl ether, 2-3 parts of diatomite, 2-4 parts of propanediol butyl ether, 7-9 parts of heat insulation slurry and 13-18 parts of deionized water. The coating disclosed by the invention is fast in drying, high in hardness of a paint film after curing, smooth, good in color and luster, very high in adhesion and good in wear resistance; the deionized water is adopted as a thinner, thereby having low cost and low toxicity and being green and environment-friendly; the added heat insulation slurry has an excellent heat insulation effect; and furthermore, the coating has excellent corrosion resistance, aging resistance and water resistance, is convenient to construct and is harmless to human bodies.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a wear-resistant heat-insulating and waterproof architectural coating and a preparation method thereof. Background technique [0002] There are many ways to decorate and protect buildings, but the use of coatings is one of the simplest, most economical, and convenient for maintenance and renewal, so it is widely used in construction projects at home and abroad. Most of the exterior walls of modern buildings are constructed of reinforced concrete, cement prefabricated parts or masonry and other building materials. Exterior wall coatings must not only have good weather resistance and water resistance but also have good mildew resistance, otherwise molds will multiply and the coating will be damaged. It quickly loses its decorative effect. Due to sunlight, the temperature inside the building rises, increasing the energy consumption of the air conditioner, which has a gr...

AI Technical Summary

Problems solved by technology

Due to sunlight, the temperature inside the building rises, increasing the energy consumption of the air conditioner, which has a great impact on the environment. In addition, industrial plants, prefab houses or temporary buildings often use metal steel roofs. Under the sun, the indoor temperature will drop. At this time, the effect of using air conditioning to cool down the indoor temperature is not ideal
