Abstract

The invention proposes an in-situ preparation method of heat insulation materials, which belongs to the technical field of preparation of heat protection materials, and comprises the following steps: mixing and dispersing a heat insulation powder composition, a fiber composition, an auxiliary agent composition and a fluid carrier composition Evenly, prepare a dispersion liquid; fix the dispersion liquid in the area to be formed, and obtain a formed solid object after the flow carrier is reduced; apply composition A on the surface of the formed solid object, and then dry the composition A, and wait for the composition A to be mixed with After the shaped solid is completely dried, a thermal insulation material is obtained. It can solve the problem that the existing heat insulation materials cannot meet the heat insulation requirements of equipment areas with complex structures and small spaces, and the problems that the surface defects of the existing heat insulation materials cannot be repaired with heat insulation.

Description

technical field [0001] The invention relates to an in-situ preparation method of a heat insulating material, which belongs to the technical field of heat protection material preparation. Background technique [0002] Thermal insulation material, also known as thermal insulation material, is a key and indispensable industrial material, which is widely used in civil, chemical, electric power and other fields. According to different use temperature, the existing heat insulation materials can be divided into low temperature heat insulation materials, the use temperature range is generally 0-300 ℃; medium temperature heat insulation materials, the use temperature range is generally 300-800 ℃; high temperature heat insulation materials, use temperature The region is generally higher than 800°C. Low-temperature insulation materials are usually organic polymer materials, medium-temperature insulation materials are usually inorganic materials with poor heat resistance and low cost, ...
