Waterproof quick-dry coating for outer wall of building

Abstract

The invention discloses a waterproof quick-dry coating for the outer wall of a building. The coating is prepared from the following raw materials in parts by weight: 80-85 parts of organic silicone resin, 10-20 parts of styrene-acrylic emulsion, 5-12 parts of titanium dioxide, 1-9 parts of sodium hexametasulfate, 2-6 parts of a dispersing agent, 2-8 parts of a thickening agent, 3-5 parts of siliceous lime powder, 2-10 parts of surfactant, 2-10 parts of a drying agent, 2-8 parts of diethylene glycol monobutyl ether and 3-10 parts of pigment. The waterproof quick-dry coating for the outer wall of a building has the advantages of water proofing, quick drying, low cost and remarkable use effect, and can meet the requirement of energy conservation and environment friendliness.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a waterproof quick-drying coating for exterior walls of buildings. Background technique [0002] Traditional architectural latex coatings need to add a large amount of organic solvents such as film-forming aids to the coating, resulting in a high content of volatile organic compounds in the coating. In addition, in order to prevent corrosion and deterioration of the coating during storage and moldy coating, the coating It is also necessary to add a large amount of organic antifungal agents harmful to the human body, which directly affects the physical and mental health of users. The main variety of water-based paint is latex paint, which is mainly composed of four parts: water, emulsion, pigments and fillers, and various additives. The dispersion medium of water-based paint is water. After the paint is applied, water and a small amount of additives are volatilized from the pain...
