Abstract

The invention provides a non-toxic environmental-friendly water-resistant coating and a preparation method thereof and relates to the technical field of coating processing. The non-toxic environmental-friendly water-resistant coating is prepared from the follow raw materials in parts by weight: 48-60 parts of a polyurethane resin, 12-16 parts of an epoxy resin, 4-10 parts of an alkyd resin, 2-4 parts of organosilicone, 2-3 parts of mica powder, 1.4-2 parts of zinc oxide, 0.4-1.2 parts of graphene, 3-5 parts of linoleic acid, 0.8-1.8 parts of a leveling agent and 0.4-0.8 part of a defoaming agent. The coating provided by the invention is prepared by using methods such as mixing, modification, heating and stirring; the filming property of a common water-resistant coating is improved, the water-resistant effect of the coating is improved, and in addition, the coating is safe and environmental-friendly in raw material and free of toxic component volatilization and has the advantages of long-lasting water resistance, wearing resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of paint processing, in particular to a non-toxic and environment-friendly waterproof paint and a preparation method thereof. Background technique [0002] Waterproof coating is a kind of coating that is painted on the surface of a building and forms a thin film through the volatilization of solvent or water or the chemical reaction of the two components to isolate the surface of the building from water, thereby playing the role of waterproof and sealing. . The waterproof film formed after the waterproof coating is cured has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, and can play a waterproof, anti-seepage and protective role for related buildings and materials. [0003] The main category of waterproof materials on the market is polyurethane waterproof coatings. Such materials are generally made of polyurethane and coal tar as raw materials. The tar...
