Problems solved by technology

[0003] The advantages of organic materials are sufficient raw materials, low thermal conductivity of products, convenient construction, and mature technology. Requirements
At present, the thermal insulation fillers widely used, such as slag wool, rock wool, glass wool, expanded perlite, microporous silicon and aluminum silicate wool, are not plastic. The thermal insulation materials made of these materials are easy to form thermal bridges, resulting in The thermal insulation effect expected according to the thermal conductivity of the material cannot be achieved

Abstract

The invention provides a heat-resisting and thermal-insulating composite and a preparation method thereof. Based on phenolic resin, the thermal-insulating composite is prepared in combination with cyanate ester after preforming and mold pressing through selective matching of resin matrix and small molecule materials with a reasonable preparation process. The composite has excellent heat resistance and flame retardation and good processing performance; graphene is arranged on the outer material and can improve the corrosion resistance of the composite together with N,N-dimethyl-decanamide and strontium titanate; the composite can be applied to modular prefabticated members.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a heat-resistant thermal insulation composite material and a preparation method thereof. Background technique [0002] Insulation materials are widely used in metallurgy, non-ferrous metals, machinery, petrochemical, electric power and other fields. The thermal insulation material has the characteristics of low density, high flexibility, waterproof, etc., can collect excess heat, has good randomness, has no cavity, and can avoid tearing and falling off under negative wind pressure. Insulation materials are generally divided into inorganic and organic. Organic insulation materials mainly include polyurethane foam, polystyrene board, phenolic foam, etc. Inorganic thermal insulation materials are mainly concentrated in materials with certain thermal insulation effects such as airgel felt, glass wool, rock wool, expanded perlite, and micro-nano ther...
