Waterproof and heat-resistant architectural paint and preparation method thereof

Abstract

The invention relates to waterproof and heat-resistant architectural paint and a preparation method thereof. The paint is prepared from 15-20 kg of polyacrylate thickener, 10-15 kg of ethyl silicate component, 5-10 kg of polyvinyl alcohol, 10-15 kg of acrylic resin, 5-10 kg of bauxite powder, 5-10 kg of ultraviolet stabilizer, 5-10 kg of acrylate emulsion, 5-10 kg of heavy calcium carbonate, 15-20kg of organosilicone photocurable resin and 800-1000 kg of solvent. The preparation method specifically includes the following steps that raw materials are weighed and obtained according to each component first, the solvent is poured into a reaction still, the polyacrylate thickener, the ethyl silicate component, polyvinyl alcohol, the acrylic resin, the bauxite powder, the ultraviolet stabilizer, the acrylate emulsion, heavy calcium carbonate and the organosilicone photocurable resin are added and stirred when the solvent is heated to 30-40 DEG C, then the temperature is raised to 90 DEG C and maintained for 30 minutes, and a finished product is obtained. The paint has the advantages of being free of toxicity, smell and corrosion, causing no pollutants to the environment and having goodsealing performance, high strength and no cracks.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-temperature-resistant and waterproof coating suitable for buildings and a preparation method thereof. Background technique [0002] In the prior art, all-solid waterproof and heat-resistant paints are widely used, which have high requirements on the environment during construction. When there is a lot of dust in the environment, it will fall on the surface of the paint film, affecting the coating effect of the paint film, and heating is required. The heat preservation is around 40°C, so it can only be used as fully enclosed boards. In the grooves or wooden holes, the monomer penetrates in. Due to the inconsistent irradiation distance and inconsistent curing energy, the gloss of the matte finish will also vary greatly. Contents of the invention [0003] The object of the present invention is to provide a kind of waterproof and heat-resistant architectural coating with closed-cell ...
