Problems solved by technology

[0002] With the establishment and development of the socialist market economy, all walks of life pay more attention to the work of energy saving and consumption reduction, and the performance requirements of thermal insulation materials are getting higher and higher. Traditional thermal insulation materials are no longer suitable for the diversified needs of the market. In the process of use, the thermal conductivity value and heat loss increase with the temperature of the material. At high temperature, the structure is easily damaged, and some materials are easy to pulverize, producing irritating and carcinogenic gases, leading to the deterioration of the ecological environment.

Abstract

A thermal insulating material with low heat conductivity and long service life is prepared from aluminium silicate wool, C-fibrous fluff, asbestos, penetrant, adhesive and water by use of electrostatic principle and wet technology.

Description

Technical field [0001] The invention belongs to the technical field of the power material industry, and specifically relates to an environmentally-friendly thermal insulation material that can improve thermal insulation performance and prolong service life. Background technique [0002] With the establishment and development of the socialist market economy, all walks of life pay more attention to energy saving and consumption reduction, and the performance requirements of insulation materials are getting higher and higher. Traditional insulation materials are no longer suitable for the diversified needs of the market, and their biggest shortcomings In the process of use, the thermal conductivity value and heat loss increase with the increase of material temperature. The structure is easily damaged at high temperatures, and some materials are easy to pulverize, producing irritating and carcinogenic gases, leading to the deterioration of the ecological environment. Summary of the ...
