Waterproof heat preservation coating

Abstract

The invention provides a waterproof heat preservation coating which is composed of, by weight, 80-120 parts of acrylic elastic emulsion, 28-36 parts of poly(hydroxyethyl methacrylate), 10-20 parts of polyvinyl formal resin, 15-33 parts of cement, 5-10 parts of water, 19-30 parts of acetone, 10-20 parts of magnesium silicate, 1-3 parts of a dispersing agent, 1-10 parts of a defoaming agent, 6-10 parts of tincal, 1-5 parts of flame retardant, 1-5 parts of nano silicon dioxide, 1-5 parts of heavy calcium carbonate, 1-3 parts of a silane coupling agent, 1-6 parts of epoxy resin, 2-6 parts of sodium hexametaphosphate, 13-18 parts of furan resin, 20-40 parts of phenolic resin, 100-130 parts of butyrolactone, 150-220 parts of zinc borate, 20-40 parts of aluminium hydroxide, 12-24 parts of phosphotriester, 16-22 parts of antimonous oxide, 8-20 parts of asbestos fibers, 16-18 parts of vanadium trioxide, 5-26 parts of azodicarbonamide, 2-18 parts of benzoyl peroxide, 1-6 parts of isopropyl acrylate and 8-12 parts of butyl acetate. The waterproof heat preservation coating has extremely good weather resistance, is low in heat conduction, stable in heat preservation performance, high in softening coefficient, resistant to freeze thawing and resistant to aging; temperature resistance can reach 1800 DEG C, heat insulation and heat preservation inhibition efficiency can reach about 90%, and the heat conduction coefficient is only 03 W / m.K.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a waterproof and thermal insulation coating. Background technique [0002] With the development of my country's economy, the development of urban construction is advancing by leaps and bounds, and there are more and more high-rise buildings and bridge projects. In order to speed up the project progress and reduce costs, many construction units, coupled with natural factors such as acid rain, often have roof leaks, wall seepage or bathroom floor seepage in the completed buildings. These bring great trouble to people's life, affect the quality of life. Therefore, house leakage repair is a relatively common and extremely important task, and it is also important to choose a waterproof coating with good waterproof performance. Waterproof coatings are painted on the surface of buildings, and a thin film is formed by the volatilization of solvent or water or the chemical ...
