Heat-insulating coating additive and production method

Abstract

The invention discloses a thermal insulation coating additive, which comprises the following raw materials in parts by weight: 15-25 parts of polyamide resin, 10-20 parts of nano titanium dioxide, 10-20 parts of nano calcium carbonate, 8-14 parts of polyvinyl alcohol, 15-25 parts of silica sol, 6-12 parts of coupling agent, 20-30 parts of deionized water, 8-14 parts of thickening agent, 6-12 partsof defoaming agent, 10-20 parts of polyvinyl alcohol colloid, 12-18 parts of emulsifying agent, 20-25 parts of sodium bicarbonate and 10-20 parts of film-forming agent. The product and the method belong to the technical field of coating production. According to the heat-insulating coating additive and the production method thereof, by adding nano titanium dioxide, the reflectivity is high, the infrared radiation performance is good, the reflectivity and weather resistance of the coating can be improved, the thermal insulation effect of the coating can be enhanced, the advantages of environmental protection and energy conservation are achieved, the dispersity in the coating is excellent, the cost is low, the service life is long, and various used raw materials are cheap and easy to obtain;the additive is simple in preparation method, good in heat insulation effect, easy to popularize and use and capable of accelerating the energy conservation and emission reduction process, and components of the coating do not contain pollution components.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to a heat-insulating paint additive and a production method. Background technique [0002] "Insulation coating": refers to a recently developed functional water-based coating that blocks, reflects, and radiates near-infrared heat from the sun. It can insulate and cool the roof, save energy and reduce consumption. With short construction period and quick effect, it completely replaces the water spray system, thermal insulation cotton, foam sponge, interlayer iron sheet, etc. There are three main types of thermal insulation coatings in terms of characteristics and principles, insulating conductive thermal insulation coatings, reflective thermal insulation coatings and In addition to the above three types of heat-insulating coatings, a heat-insulating and heat-insulating coating has appeared in foreign heat-insulating functional coatings. In addition to the advantages of the a...
