Problems solved by technology

[0002] Grain storage warehouses need heat insulation, water resistance, and moisture resistance. Water-based acrylic paints are often used as exterior wall coatings, but this paint cannot be heat-insulated and cannot meet the heat insulation requirements; The surface peels off in a large area, which cannot meet the requirements of water resistance and moisture resistance

Abstract

The present invention provides a preparation method of exterior wall coating incapable of absorbing sunlight. 40kg of toluene, 15kg 120# gasoline are added in a reactor with a high-speed shearing and emulsion machine for fully mixing. Then 8kg of alkyd resin, 4.5kg of VAE, 2kg of DBP and 10kg of chloroprene rubber are added. The mixture is sheared and emulsified for one hour and ten minutes with a high-speed shearing and emulsification machine rotating at a speed of 1500 rounds per minute. After pigment is added, the mixture continues to be emulsified and ground. When the fineness of the materials reaches below 60 Mu m, the product is prepared. The present invention has the advantages of sunlight radiation resistance, good water resistance, strong anti-aging properties, and strong corrosion resistance.

Description

technical field [0001] The invention relates to a method for preparing an exterior wall paint that does not absorb sunlight. Background technique [0002] Grain storage warehouses need heat insulation, water resistance, and moisture resistance. Water-based acrylic paints are often used as exterior wall coatings, but this paint cannot be heat-insulated and cannot meet the heat insulation requirements; The surface peels off in a large area, which cannot meet the requirements of water resistance and moisture resistance. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, provide a kind of preparation method of exterior wall coating that does not absorb sunlight. [0004] The technical scheme of the present invention is: a kind of preparation method of exterior wall coating that does not absorb sunlight, it is characterized in that: 40kg toluene, 15kg120# gasoline are added in the reactor with high-speed shearing ...
