Abstract

The invention discloses a preparation method of a decorative silicate heat-insulation water-resistant coating. The preparation method comprises the following step: weighing pure water, emulsified silicone oil, ultramarine, 2-butyl mercaptan, organic montmorillonite, polyacrylamide, silicon dioxide, hydrochloric acid, PVA, supervinyi chloride resin, polyvinyl formal, cyclohexanone, n-butyl acetate, butyl acrylate and methylbenzene. The coating is good in heat insulation effect, high in weather resistance and high in thixotropy, and can resist high temperature of 900 DEG C without falling off, the coating ductility is 300% to 700%, and the tensile strength is 2 to 4 MPa; the product is high in strength after film formation, the adhesive force is one level, the coating is high in corrosion resistance and cannot corrode wall, metal, wood and plastic respectively and is resistant to washing 6000 to 8000 times, and the hardness is 5 H; the coating is 10 to 20 d in water resistance, free of cracking, bubbling or peeling, high in storage stability, good in construction performance and good in glossiness, and the flexibility is 1 mm; the coating is free of bubbling or cracking after being soaked for 6 to 10 d in a sodium chloride solution, quick in drying, and resistant to artificial aging for 800 to 1000 h.

Description

technical field [0001] The application belongs to the field of decorative materials, in particular to a method for preparing a silicate thermal insulation and water-resistant coating for decoration. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.12. The development of thermal insulation materials is rapid, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. Every ton of mineral wool insulation products used in buildings can save one ton of oil a year. [0003] R&D background: Traditional thermal insulation materials are mainly to increase the gas phase porosity and reduce the thermal conductivity and conductivity. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-base...
