Problems solved by technology

[0003] The technical problem to be solved by the present invention is to propose a high-temperature-resistant water-based paint and a preparation method thereof for the above shortcomings of the prior art. The water-based paint not only has strong friction resistance, but also has good adhesion and is not easy to fall off. The water-based paint Strong high temperature resistance, good corrosion resistance and long service life. The water-based coating will not cause problems such as foaming, cracking, whitening or even delamination after long-term use, and can be used in harsh environments with a wide range of applications. And it has environmental protection effect and reduces cost

Abstract

The invention discloses a high-temperature-resistant water-borne coating and a preparation method thereof. The high-temperature-resistant water-borne coating consists of the following materials in parts by weight: 82 to 85 parts of epoxy-modified organic silicone resin, 30 to 38 parts of bisphenol-A epoxy resin, 11 to 13 parts of water-based acrylic resin, 18 to 24 parts of graphite powder, 10 to 13 parts of polydimethylsiloxane, 5 to 8 parts of calcium carbonate, 8 to 10 parts of titanic oxide, 60 to 65 parts of deionized water, 10 to 12 parts of peal powder, 5 to 8 parts of titanium dioxide, 8 to 12 parts of kaolin, 5 to 8 parts of Rhine powder as release agent, 3 to 5 parts of thermal carbon black MT and 3 to 5 parts of toluene. Not only is the corrosion resistance of the water-borne coating good, but also the adhesion is good, so the water-borne coating cannot easily shed; moreover, colors are diversified; the service life is long, and problems, such as blistering, cracking, whitening and even leafing, cannot take place after the water-borne coating is used for a long time.

Description

Technical field [0001] The present invention involves a coating, which is specifically a high -temperature water -resistant coating and preparation method. Background technique [0002] At present, water -based coatings can be widely used in electrical, metallurgy, petroleum, aviation, chemical, medicine, food and other industries, but the coatings on the surface of the equipment are poor, especially for equipment exposed to outdoor. For a long time, for a long timeDans and rain, causing coatings to drop, damage the surface of the equipment, reduce the service life of the equipment, and increase costs. Invention content [0003] The technical problem to be solved by the present invention is to propose a high -temperature water -resistant water -resistant coating and preparation method for the shortcomings of the above technology.High temperature resistance, good corrosion resistance, long service life, the long -term use of this water -based coating will not occur, cracks, white...
