A self-cleaning waterproof coating

Abstract

The invention discloses a self-cleaning waterproof coating, which is composed of the following raw materials in parts by weight: silicon acrylic emulsion 62-70, linseed oil 1-2, zinc dihydrogen phosphate 1-2, lauroyl sarcosine Sodium 1-2, dimethyl glutarate 2-3, maleic anhydride grafted polypropylene 2-3, dimethyl diallyl ammonium chloride 1-2, tetrabutyl ammonium bromide 1-2, Lauric acid diethanolamide 1.2-2, isopropanol 1-2, nano bauxite 3-5, vermiculite powder 6-8.5, ascorbic acid 0.5-1, film-forming aid 6-8, deionized water 10-17, The waterproof coating of the present invention has good thermal insulation effect, strong wiping resistance, strong water resistance, good self-cleaning effect, stable coating film, strong adhesion, good acid and alkali resistance, and good corrosion resistance. Good stability and long shelf life.

Description

technical field [0001] The invention mainly relates to a coating, in particular to a self-cleaning waterproof coating. Background technique [0002] The traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, sealing ointments, and rigid waterproof materials mainly based on cement substrates, with the addition of liquid chemicals and other additives. Most of the waterproofing projects in my country use traditional waterproofing materials. Traditional waterproofing materials have shortcomings such as poor aging resistance, low tensile strength, and temperature sensitivity. Traditional waterproof coatings are used for roof waterproofing, which are easy to cause aging, cracking, deformation, breaking, delamination and other phenomena. For indoor waterproofing, construction is difficult for places with complex shapes, and for leakage, the quality is more difficult to guarantee. Every few years, it will cos...

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.
