Abstract

The invention discloses a novel thermal insulation building material and a preparation method thereof. The novel thermal insulation building material is prepared from the following raw materials in parts by weight: 30-60 parts of silicate cement, 15-26 parts of coated expanded perlite, 10-30 parts of plant fibers, 12-24 parts of superfine glass wool, 10-15 parts of diatomite, 30-60 parts of polymethylene polyphenyl isocyanate, 6-18 parts of microporous calcium carbonate, 5-15 parts of a composite flame retardant, 13-19 parts of floating bead, 3-10 parts of an adhesive and 2-15 parts of an exciting agent. By adopting the glass wool and the plant fibers as main raw materials of a thermal insulation material, the novel thermal insulation building material has the characteristics of low heat conductivity coefficient and small density and is easy in taking materials and low in cost.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a novel thermal insulation building material and a preparation method thereof. Background technique [0002] Insulation materials are widely used in insulation materials for refrigerators, cold storages, freezers, refrigerated vehicles, buildings, storage tanks and pipelines, etc. In recent years, the research on rigid foam plastics abroad has developed rapidly and has been widely used. However, due to the high cost of domestic rigid foam plastics, the relative development is relatively slow, so the domestic market has yet to be further developed. In addition, thermal insulation materials require not only light weight, but also excellent compressive strength, modulus and dimensional stability. With the development of science and technology and the continuous improvement of living standards, environmentally friendly thermal insulation materials have become an important re...
