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 an easy-to-process heat-preservation composite material and a preparation method of same. In the invention, phenolic resin is used as a basis with combination of epoxy resin. Through selection and combination between resin matrix and a small-molecular substance with a reasonable preparation technology, the raw materials are pre-shaped and then are subjected to mould pressing, so that the produced heat-preservation composite material has excellent processability and has excellent heat resistance and flame-retarding property. Graphene is arranged on the outer side, so that the anticorrosion performance of the material is enhanced by means of the graphene along with N,N-dimethyl lauryl amine and strontium titanate. The material can be applied to modularized performs.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to an easy-to-process 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, no cavity, and can avoid negative wind pressure tearing and falling off. Thermal insulation materials are generally divided into two types: 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 a certain thermal insulation effect, such as aerogel felt, glass wool, rock wool, expanded perlite, and m...
