Problems solved by technology

[0003] Although the commonly used thermal insulation coatings have a certain thermal insulation effect, they are used in a large amount, and the thermal insulation and thermal insulation effects are limited. For barrier type thermal insulation coatings, due to the structural defects of the material itself, It causes weak impact resistance, long drying cycle, large drying shrinkage, and high moisture absorption rate. Therefore, it is an inevitable trend in the field of architectural coatings to develop a coating with excellent thermal insulation performance and good physical and chemical properties.

Abstract

The invention discloses building insulation coating. The building insulation coating comprises diatomite, light calcium carbonate, bentonite, ethylene carbonate, 2-cyanoacrylate, triethyleneglycolmonoethylether, hydroxypropyl methyl cellulose, N-oleo sarcosine octadecyl amine, silicon dioxide, and ethyl acetate. The preparing method includes: adding the diatomite, the bentonite, the hydroxypropyl methyl cellulose, the N-oleo sarcosine octadecyl amine and the silicon dioxide into water, performing periodic heating and stirring, drying mixed liquid to obtain solid, crushing the solid, adding the crushed solid into mixed liquid of the ethylene carbonate, the 2-cyanoacrylate and the ethyl acetate, performing heating and stirring in a reflow device, and allowing cooling to room temperature after reflowing; adding the remaining components, and performing stirring at the room temperature before grinding so as to obtain the building insulation coating. The building insulation coating has good thermal insulation, good impact strength and good other physical and chemical characteristics and is widely applicable to the field of coating insulation.

Description

technical field [0001] The invention belongs to the technical field of preparation of architectural coatings, and in particular relates to a thermal insulation coating for buildings and a preparation method thereof. Background technique [0002] Coatings are one of the indispensable materials for the development of the national economy. Due to the many special functions of coatings, there are many varieties of coatings. Architectural coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. The decorative function is to improve the appearance value of a building by beautifying it. It mainly includes the conceptual design of flat color, pattern and gloss and the conceptual design of three-dimensional pattern. However, it must be matched with the shape of the building itself and the size and shape of the base material itself, so that it can be fully utilized. The protection...
