The invention relates to a preparation method of coating for the exterior wall, 40 kg of toluene and 15 kg of gasoline 120 # are added in a reaction kettle and are fully mixed, then 8 kg of alkyd resin, 5 kg of VAE, 2 kg of DBP and 10 kg of chloroprene rubber are added, and are sheared and emulsified through a high-shear emulsifying machine,, pigment is added, and the emulsifying and the grinding operations are continued. When fineness of the material reaches below 60 pm, the materials are filtered and filled. The preparation method has the advantages of sunlight radiation resistance, good water resistance, strong anti-aging performance and strong corrosion resistancy.
Description
technical field [0001] The invention relates to a preparation method of exterior wall paint. Background technique [0002] In the prior art, water-based acrylic paints are often used as exterior wall coatings for grain storage warehouses, which cannot be insulated, and often have large areas of cracks, which make the walls gradually soaked in water, causing large areas of the walls to peel off, which cannot meet the requirements of heat insulation, water resistance, and moisture resistance. special requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, and provide a preparation method of exterior wall paint, which is anti-sunlight radiation, water-resistant, corrosion-resistant, quick-drying, and strong adhesion. [0004] The technical scheme of the present invention is: a kind of preparation method of exterior wall paint, it is characterized in that: 40kg toluene, 15kg120# gasoline are added ...
