Waterproof paint for exterior wall

Abstract

The invention discloses a waterproof paint for an exterior wall. The waterproof paint is prepared from the following raw materials in parts by weight: 53-60.2 parts of a silicone acrylic emulsion, 0.1-0.2 part of tantalum carbide, 0.3-0.7 part of copper 8-hydroxyquinoline, 0.1-0.3 part of fatty alcohol polyoxyethylene ether ammonium sulfate, 1-2 parts of potassium tetraborate, 0.4-0.6 part of ammonium metavanadate, 1-2 parts of polyurethane, 2-3 parts of polypropylene oxide glycol, 1.3-2 parts of sodium carboxymethylcellulose, 0.7-1 part of N, N-diethyl aniline, 0.1-0.2 part of trimethyl hexamethylene diamine, 4-6 parts of titanium dioxide, 8-10 parts of light calcium carbonate, 5-6 parts of coalescing agents and 10-15 parts of deionized water. The waterproof paint for the exterior wall is strong in seepage force resistance, remarkable in waterproof performance, good in weather resistance and strong in resistance to acid and base, has good high temperature resistance, is free from chemical odors which are harmful to human body and simple to operate, and is an ideal waterproof paint for the exterior wall.

Description

technical field [0001] The invention mainly relates to a coating, in particular to a waterproof coating for exterior walls. 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 takes a lot of money and labor to repair every f...

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 building.
