Problems solved by technology

Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature.
Traditional waterproof coatings are used for roof waterproofing, which is easy to cause aging, cracking, deformation, breakage, delamination, etc. When used for indoor waterproofing, it is difficult to construct for places with complex shapes, and it is even more difficult to guarantee the quality of leakage. It takes a lot of money and labor to repair every few years, which not only disrupts people's normal life, work and production order, but also affects the service life of the entire self-cleaning building.

Abstract

The invention discloses a self-cleaning waterproof coating which comprises the following raw materials in parts by weight: 62-70 parts of silicone acrylic emulsion, 1-2 parts of linseed oil, 1-2 parts of zinc dihydrogen phosphate, 1-2 parts of sodium lauroyl sarcosine, 2-3 parts of dimethyl glutarate, 2-3 parts of maleic anhydride grafted polypropylene, 1-2 parts of dimethyl diallyl ammonium chloride, 1-2 parts of tetrabutylammonium bromide, 1.2-2 parts of laurate dihydroxyethylamide, 1-2 parts of isopropanol, 3-5 parts of nano bauxite, 6-8.5 parts of vermiculite powder, 0.5-1 part of ascorbic acid, 6-8 parts of film-forming assistant and 10-17 parts of de-ionized water. The waterproof coating has a very good heat insulation effect, and has good wiping resistance, waterproofness, self-cleaning effect, adhesiveness, acid-base resistance, corrosion resistance and storage stability and long shelf life; the formed coating is stable.

Description

technical field [0001] The invention mainly relates to a coating, in particular to a self-cleaning waterproof coating. Background technique [0002] Traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, and sealing ointments, as well as rigid waterproof materials that are based on cement substrates and added with liquid medicine and other additives. Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature. Traditional waterproof coatings are used for roof waterproofing, which is easy to cause aging, cracking, deformation, breakage, delamination, etc. When used for indoor waterproofing, it is difficult to construct for places with complex shapes, and it is even more difficult to guarantee the quality of leakage. It will cost a lot of money and labor to repair every fe...
