Problems solved by technology

During the use of existing architectural waterproof coatings, the waterproof film formed by curing tends to close the capillary pores of the base material, resulting in the inability of the moisture in the base to escape from the inside of the wall, and the weather resistance of the waterproof film is not good, resulting in a short service life

Abstract

The invention discloses a silicone waterproof coating. In parts by weight, the raw materials of the silicone waterproof coating include: 100-120 parts of potassium methyl silicate, 60-80 parts of dimethylsiloxane, 15 parts of silane coupling agent ~20 parts, 15~20 parts of methyl silicone oil, 50~60 parts of nano inorganic powder, 10~30 parts of emulsifier, 20~40 parts of stabilizer, 100~150 parts of diluent, 3~6 parts of thickener; The nano-inorganic powder is composed of the following components in parts by weight: 60-80 parts of nano-silica, 20-30 parts of nano-alumina, 8-10 parts of nano-zirconia, 10-15 parts of nano-hydroxyphosphorus Limestone; the silicone waterproof coating forms a reticular waterproof film on the surface and inside of the wall to improve the waterproof effect. The waterproof film will not close the capillary pores of the base material, and moisture can still escape from the wall to achieve waterproof and breathable effects. , and good weather resistance, long service life of waterproof coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a silicone waterproof coating. Background technique [0002] Building waterproof coating has the characteristics of simple construction and strong adaptability to complex structures, and is widely used in building construction. Waterproof coatings are mainly used for waterproofing, moisture-proofing and anti-seepage of some structural parts of buildings that may be eroded by water. Therefore, there are certain requirements for high-temperature resistance and anti-corrosion performance of waterproof coatings. During the use of existing architectural waterproof coatings, the waterproof film formed by curing tends to close the capillary pores of the base material, resulting in the inability of the moisture in the base to escape from the inside of the wall, and the weather resistance of the waterproof film is not good, resulting in a short service life .
