Abstract

The invention discloses a thermal insulation coating, which is characterized by being prepared from 55-65 parts of a film-forming polymer, 15-20 parts of attapulgite, 1-3 parts of graphene foam, 1-3 parts of metal organic framework, 2-5 parts of hollow Bi-Ti-O, 1-3 parts of tetrakis(diethylamino) hafnium, 10-15 parts of a solvent, 2-6 parts of an antifoaming agent and 1-3 parts of a dispersing agent. The invention also discloses a preparation method of the thermal insulation coating. The method comprises the steps of: conducting ball milling to obtain a fine powder, putting the fine powder andthe solvent into an agitator tank, and conducting dispersing at a low speed; adding the attapulgite, the defoaming agent, and the dispersing agent, and conducting dispersing at a high speed; and thenadding the tetrakis(diethylamino) hafnium, and conducting dispersing at a medium speed for 10 to 15 minutes. The thermal insulation coating disclosed by the invention has the advantages of good thermal insulation effect, large adhesion to a wall body and excellent comprehensive performance.

Description

technical field [0001] The invention relates to a building material, in particular to a thermal insulation coating and a preparation method thereof. Background technique [0002] With the rapid development of social economy, more and more buildings have sprung up, showing high-level requirements for "building height, building form and building quality". Among them, thermal insulation is an important measure to keep the indoor temperature constant, increase the temperature difference between indoor and outdoor, create a suitable indoor thermal environment and save energy. [0003] The use of coatings with thermal insulation functions on the interior and exterior walls of buildings is an effective way for buildings to save energy and reduce consumption. It can not only realize the original decoration, protection and anti-mildew functions of coatings, but also play a role in heat insulation. Thermal insulation coatings in the prior art mostly use acrylic resin, polyester resin...
