Waterproof corrosion-resistant heat-insulating coating

Abstract

The invention relates to waterproof corrosion-resistant heat-insulating coating. The waterproof corrosion-resistant heat-insulating coating comprises the following components in percentage by weight: 40 to 60 percent of styrene-acrylate emulsion, 5 to 10 percent of hollow glass microbead, 9 to 20 percent of sepiolite, 3 to 8 percent of titanium dioxide, 1 to 5 percent of light calcium carbonate, 1 to 5 percent of heavy calcium carbonate powder, 2 to 6 percent of zinc white, 5 to 15 percent of deionized water, 0.2 to 1 percent of thickening agent, 0.2 to 1 percent of defoaming agent, 0.2 to 1 percent of antifreezing agent, 0.2 to 1 percent of preservative, 0.2 to 1 percent of bactericide and 0.5 percent of essence. The preparation method comprises the following steps: adding the styrene-acrylate emulsion, the hollow glass microbead, the sepiolite, the titanium dioxide, the light calcium carbonate, the heavy calcium carbonate powder, the zinc white, the thickening agent, the defoaming agent, the antifreezing agent and the deionized water into a reaction kettle; emulsifying and homogenizing for 40 minutes; standing for more than 2 hours; adding the bactericide and the essence; and stirring uniformly. The waterproof corrosion-resistant heat-insulating coating is non-toxic and pollution-free in raw materials and low in cost, has good waterproof, corrosion-resistant and heat-insulating effects, saves energy and reduces consumption.

Description

technical field [0001] The invention belongs to the technical field of daily chemical industry, and in particular relates to a coating for building. technical background [0002] At present, domestic roofs, roofs, pipeline waterproofing, anti-corrosion, and thermal insulation are all undertaken by different materials, and there is no one material that has two or more functions at the same time. Insulation materials mainly include polyurethane foam, perlite, silica powder, rock wool, slag, etc.; waterproof materials have developed rapidly in recent years and can be roughly divided into three categories: (1) oil-cloth waterproof materials, such as traditional petroleum asphalt felt ( Since 2000, new buildings are forbidden to use) waterproof, water-emulsion rubber asphalt felt paint waterproof, neoprene paint plus non-woven fabric waterproof, etc., the above materials not only pollute the environment, construction is troublesome, but also poor waterproof and easy to leak; ( 2...
