[0002] With the development of society, the exterior walls of some buildings are gradually processed with thermal insulation materials, which can effectively improve the thermal insulation and thermal insulation performance of buildings. Thermal insulation materials can be divided into organic materials and inorganic materials according to their composition. However, due to the influence of processing methods and internal material components, the existing thermal insulation materials have low density, poor water resistance, brittle quality, poor strength and relatively high thermal conductivity, resulting in poor thermal insulation.

Abstract
The invention discloses a multi-functional thermal insulation material which comprises the following components in parts by mass: 65-85 parts of gypsum; 10-30 parts of a lightweight aggregate; 0.15-0.35 parts of cellulose; 0.5-1 part of rubber powder; 0.05-0.1 parts of a thixotropic agent; 0.1-0.2 parts of a retarder; and 4-7 parts of ash calcium. The lightweight aggregate is one or more of vitrified microbeads, expanded perlite, polyphenyl granules, ceramic microbeads, sepiolite or closed-cell perlite. The cellulose is one or more of hydroxypropyl methyl cellulose, ethyl cellulose or carboxymethyl cellulose. The rubber powder is one or more of dispersible latex powder, VAE rubber powder or resin rubber powder. The thixotropic agent is one or two of fumed silica, organic bentonite, asbestos, magnesium aluminum silicate or kaolin. The material has the advantages that the method for preparing the multi-functional thermal insulation material is simple and easy to implement, the thermal insulation material has the characteristics of low density, high strength and low heat conductivity coefficient, subsequent construction operation is simple and convenient, and manpower can be greatly saved.
