Thermal insulation material with anti-corrosion effect

Abstract

The invention relates to technical field of research, development and manufacture of thermal insulation materials, and discloses a thermal insulation material with an anti-corrosion effect. The thermal insulation material is prepared from the following components: 40 to 45 parts of quartz fiber, 20 to 25 parts of potassium hexatitanate whisker, 14 to 18 parts of starch solution, 12 to 15 parts ofaerogel silicon dioxide, 10 to 15 parts of silicone oil, 10 to 12 parts of amide, 4 to 6 parts of aluminum polychlorid, 1.0 to 1.5 parts of glass powder, 0.8 to 1.0 part of titanium dioxide, and 14 to20 parts of water. The thermal insulation material improves the corrosion resistant performance and waterproof performance, and as potassium hexatitanate whisker has excellent mechanical property andcorrosion resistance, but is difficult to be adhered to fiber and particularly adhered to silicon oxide fiber products containing more residue balls, the thermal insulation material further improvesthe corrosion resistant performance through modification, and further has the advantages of thermal insulation, fire protection, corrosion protection, economical efficiency and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of R&D and production of heat insulation materials, and in particular relates to a heat insulation material with anti-corrosion effect. Background technique [0002] Thermal insulation materials, materials that can block the transfer of heat flow, are also called thermal insulation materials. Traditional thermal insulation materials, such as glass fiber, asbestos, rock wool, silicate, etc., new thermal insulation materials, such as airgel felt, vacuum panels, etc. Heat insulation materials are divided into three categories: porous materials, heat reflective materials and vacuum materials. The former uses the pores contained in the material itself to insulate heat, because the thermal conductivity of the air or inert gas in the pores is very low, such as foam materials, fiber materials, etc., and heat reflective materials have a high reflection coefficient, which can reflect heat. Gold, silver, nickel, alum...

AI Technical Summary

Problems solved by technology

[0003] In civil air defense projects, porous heat insulation materials are mostly used. The pore structure determines that it is easy to absorb moisture and get damp, especially under the action of corrosive liquids and gases, it will lose part of its efficacy and increase the heat insulation coefficient. The existing problem is that it is not suitable for heat insulation Materials have high requirements on fire resistance, but ignore their anti-corrosion properties, resulting in a great waste of resources. Thermal insulation materials are usually loose in texture and low in thermal conductivity, and can resist changes in high and low temperatures. However, in the presence of corrosive substances , its physical, chemical and mechanical properties will be greatly affected, and there will be serious instability problems
