Abstract

The invention discloses a building thermal insulation coating material and a preparation method thereof, and relates to the technical field of coating materials, wherein the raw materials comprise, byweight, 30-50 parts of an elastic emulsion, 2-5 parts of a film-forming aid, 1-3 parts of a dispersing agent, 1-3 parts of a wetting agent, 1-5 parts of a multifunctional aid, 30-50 parts of deionized water, 1-10 parts of glass hollow micro-beads, 1-15 parts of SiO2 aerogel, 1-30 parts of titanium dioxide and 1-3 parts of a thickening agent. According to the invention, the raw materials interactwith each other; the coating has excellent elasticity, excellent elongation and good anti-crack effect, can cover the existing tiny cracks and prevent the cracks caused by the cracking of the wall body, further is excellent in stain resistance, weather resistance, water resistance, alkali resistance and other performances, has low thermal conductivity, can achieve good heat insulation effect through thin-layer construction, and can effectively reduce the surface temperature of a building by more than 20 DEG C, and reduce the indoor temperature by about 7-10 DEG C; and the coating material reaches the performance indexes of the superior products of the national standard GB / T 9755-2001 of synthetic resin emulsion coatings for exterior wall, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a building thermal insulation coating and a preparation method thereof. Background technique [0002] As people's requirements for the comfort of the living environment are getting higher and higher, heating and cooling devices are becoming more and more popular, and building energy conservation is increasingly concerned by people. According to statistics, the current energy consumption of buildings accounts for about 30% of the energy consumption of the whole society, the most important of which is the use of air conditioners. In hot summer, the sun’s rays are directly irradiated to the roof, and then absorbed by the roof and transferred into the house, increasing the indoor temperature. The heat absorbed by the roof can reach 46% of the total heat absorbed by the house. Therefore, improving the thermal insulation performance of buildings is an important building energy-saving...
