Abstract

The invention discloses a special novel heat insulation material for a wall and a preparation method thereof. The special novel heat insulation material is prepared from the following raw materials in parts by weight: 30 to 60 parts of silicate cement, 10 to 30 parts of plant fiber, 15 to 26 parts of polyols, 30 to 60 parts of polyaryl polymethylene isocyanate, 6 to 18 parts of microporous calcium carbonate, 12 to 24 parts of superfine glass wool, 5 to 15 parts of composite flame retardant agent, 13 to 19 parts of calcium silicate, 3 to 10 parts of adhesive, 8 to 18 parts of penetrant, and 2 to 15 parts of slipping agent. The special novel heat insulation material has the advantages that the glass wool and the plant fiber are used as the main raw materials of the heat insulation material; the heat conduction coefficient is low, and the density is small; the obtaining of materials is easy, and the cost is low.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a new type of thermal insulation material specially used for walls 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 ...
