Abstract

The invention relates to the technical field of architectural coatings and provides a heat-preserving heat-insulating coating material. The heat-preserving heat-insulating coating material comprises the following raw materials in parts by mass: 8-20 parts of deionized water, 30-40 parts of acrylic resin emulsion, 1-12 parts of xonotlite calcium silicate, 1-9 parts of kaolin, 5-30 parts of rutile type titanium dioxide, 0.1-0.8 part of defoamer, 2-5 parts of film forming assistant, 0.2-0.4 part of mildew preventive, 0.3-0.6 part of leveling agent, 1-2 parts of dispersant, 1-2 parts of humectantand 1-3 parts of thickener, wherein the sum of parts by mass of all the above ingredients is 100. The invention further provides a preparation method for the heat-preserving heat-insulating coating material. The heat-preserving heat-insulating coating material provided by the invention is readily available in employed raw materials, low in cost and simple in preparation process, coatings are goodin heat-insulating performance, and thus, building energy conservation can be achieved.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to a thermal insulation coating and a preparation method thereof. Background technique [0002] The building area built in my country every year is as high as 1.6 to 2 billion cubic meters, which exceeds the total building area of ​​all developed countries. Due to poor thermal insulation performance, the building that can save energy by 50% in my country has a heating energy consumption of about 1.5 times. Therefore, building energy conservation is imperative, and it is imminent to optimize the thermal insulation system of buildings. The energy consumption of buildings accounts for about 30% to 40% of the total energy consumption of the society. Building exterior wall insulation technology is an important means of building energy conservation. [0003] The traditional thermal insulation of buildings usually adopts external organic or inorganic insulation b...
