Problems solved by technology

Among them, solvent-based coatings and reactive coatings will emit volatile organic compounds (VOCs) into the atmosphere during production and construction to cause pollution. VOCs can stimulate and damage the central nervous system, hematopoietic organs, and respiratory system of the human body. Cause convulsions, coma and even death, therefore, VOC is extremely harmful to human health

Abstract

The invention discloses single component waterproof coating and the preparation method. 50 percent to 80 percent of emulsion, latent solvent, dispersing agent and wetting agent are mixed with 40 percent to 60 percent of anti-foaming agent and are stirred at the rotating speed of 300 rpm to 700 rpm, pigment and filler are added during the stirring process, then the dispersing operation is performed at the rotating speed of 2000 rpm to 4000 rpm, slurry with the fineness lesser 50 um is obtained, and the residual anti-foaming agent is added. After the anti-foaming operation is performed, anticorrosion agent, film forming auxiliary agent, residual emulsion, thickening agent and water are added and evenly stirred at the rotational speed of 300rpm to 700 rpm, and the single component waterproof coating is obtained. The method has the advantages that the construction technology of the coating is simple and convenient, the film-forming process is finished mainly depending on the volatilization of the water and the interfusion of the latex particles, no VOC is discharged, no organic solvent is effused, the single component waterproof coating has no environmental pollution and combustion, the construction is safe, and the coating is an environmental protective-type single component waterproof coating.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to an environment-friendly single-component waterproof coating without VOC emission. [0002] The invention also relates to a preparation method of the waterproof paint. Background technique [0003] Leakage in buildings will not only damage the interior decoration and equipment of the project, but also damage the structure of the project in severe cases, making it lose its function, causing scrap and even endangering people's lives. Adopting waterproof technology to prevent water seepage and water leakage of buildings is a kind of waterproof method that has just begun to be used in the late 1950s. The waterproof coating is a viscous liquid at room temperature, and can form a seamless waterproof coating film after coating and curing. It is especially suitable for construction on detailed structures such as facades, internal and external corners, and narrow places. It has both bonding and wat...
