Problems solved by technology

However, the materials currently used are not ideal in various properties, especially in terms of heat preservation, acid and alkali resistance, and weather resistance, which cannot meet people's needs.
At present, the most commonly used external wall insulation material is polystyrene plastic foam board, and its main material is polystyrene resin. Because of its high transparency, good rigidity and good chemical corrosion resistance, it has always been favored by people. However, it has the disadvantages of large specificity, large thermal conductivity, prone to stress cracking, and high cost.

Abstract

The invention discloses a thermal insulation material, which comprises the following raw materials according to the mass ratio: 10-25 parts of volcanic ash, 75-90 parts of environmental protection glue, and white emulsion. ~30 parts, wherein, the environmental protection glue is formed by mixing 100 parts of water and 6~10 parts of polyvinyl alcohol. The thermal conductivity of the thermal insulation material of the present invention is only 0.036, the thermal insulation performance is excellent, the bonding strength is high, and it has good acid and alkali corrosion resistance and weather resistance. The thermal insulation material can replace the traditional thermal insulation material, and has unique advantages in the application field of building coating in industrial and mining enterprises.

Description

technical field [0001] The invention belongs to the application field of building coating, and in particular relates to a thermal insulation material for exterior walls. Background technique [0002] With the implementation and development of building energy conservation, thermal insulation materials and products have been paid more and more attention by people. However, the currently used materials are not ideal in various properties, especially in terms of heat preservation, acid and alkali resistance, and weather resistance, which cannot meet people's needs. At present, the most commonly used external wall insulation material is polystyrene plastic foam board, and its main material is polystyrene resin. Because of its high transparency, good rigidity and good chemical corrosion resistance, it has been favored by people. However, it has the disadvantages of large specificity, high thermal conductivity, prone to stress cracking, and high cost. Contents of the invention ...
