A kind of mineral fiber thermal insulation material and preparation method thereof

Abstract

The invention belongs to the technical field of composite material preparation, and discloses a mineral fiber thermal insulation material and a preparation method thereof. The mineral fiber thermal insulation material is composed of 12-16 parts of modified silicon dioxide, 10-13 parts of nano titanium dioxide, oxidized 8-10 parts of aluminum, 8-10 parts of calcium oxide, 6-7 parts of clay, 8-12 parts of solvent, 3-5 parts of penetrant, 1-2 parts of dispersant, and 2-3 parts of binder. The present invention uses modified silicon dioxide as the main raw material for the preparation of heat-insulating materials. The particle distribution of modified silicon dioxide is more uniform, which can effectively improve the heat-insulating effect of heat-insulating materials; and nanometer titanium dioxide, calcium oxide and Alumina can improve the strength and maintain the stability of the thermal insulation material, and the performance of the prepared thermal insulation material is better; the preparation method of the invention is simple, the energy consumption is low, and it can realize large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a mineral fiber thermal insulation material and a preparation method thereof. Background technique [0002] At present: thermal insulation materials refer to materials that can block the transfer of heat flow, also known as thermal insulation materials. Thermal insulation materials are used for building envelope or thermal equipment, materials or material composites that resist heat flow transfer, including both thermal insulation materials and cold insulation materials. On the one hand, thermal insulation materials meet the thermal environment of building space or thermal equipment, and on the other hand, they also save energy. At present, the thermal insulation materials used in the market mainly include rock wool, glass wool, expanded perlite, foam concrete, etc. These materials have the advantages of low price, non-combustible materials, an...

AI Technical Summary

Problems solved by technology

At present, the thermal insulation materials used in the market mainly include rock wool, glass wool, expanded perlite, foam concrete, etc. These materials have the advantages of low price, non-combustible materials, and good adhesion to the wall, but they also have High density, poor thermal insulation, large loss when laying thicker materials, high moisture absorption, poor shock resistance and poor environmental performance. Therefore, the use of these inorganic thermal insulation materials often cannot meet energy-saving standards, and asbestos or glass wool Building insulation materials themselves contain a large amount of harmful substances, which cannot meet human health requirements

[0003] Through the above analysis, the problems and defects of the existing technology are: the thermal insulation materials currently used have high density, poor thermal insulation performance, high hygroscopicity, poor seismic performance and poor environmental protection performance, which cannot meet the construction needs
