Nut shell foam grain cement composite thermal insulation material

Abstract

The invention relates to a nut shell foam grain cement composite thermal insulation material. The nut shell foam grain cement composite thermal insulation material is formed by uniformly mixing and stirring 55-65kg of high-density polyphenyl granules uniformly wrapped with polymer glue outside, 80-90kg of No. 425 silicate cement, 10-15kg of cellulose ether, 70-80kg of polymer rubber powder and 5-15kg of polypropylene fiber yarns. The nut shell foam grain cement composite thermal insulation material has the advantages of having little hydroscopicity, low coefficient of heat transfer, wide temperature range, light weight, firmness and durability, convenience and the like, being a green environment-friendly material, having unique fireproof performance, and completely according with fireproof, heat-retaining, environment-friendly and energy-saving requirements advocated by our country.

Description

technical field [0001] The invention relates to a building material, in particular to a solid-shell foam cement composite heat-insulation material which not only has energy-saving and heat-preservation functions, but also has fireproof performance. Background technique [0002] Building energy conservation is a major policy of the country, and the task of energy conservation and emission reduction is very arduous. The new index of building energy conservation has been included in the national "Twelfth Five-Year Plan", which is a hard task that must be completed and is also a need for the development of a low-carbon economy. With the continuous deepening of the reform of wall materials in the country, the application proportion of new wall materials and energy-saving thermal insulation materials has increased year by year, but new requirements have been put forward for the performance requirements and construction methods of thermal insulation materials. Currently commonly us...
