Heat-insulating material

Abstract

The invention discloses a heat-insulating material which comprises the following raw materials in parts by mass: 10-25 parts of volcanic ash, 75-90 parts of environment-friendly adhesive and white latex accounting for 10-30 parts on the basis of 100 parts of volcanic ash and environment-friendly adhesive; and the environment-friendly adhesive is prepared by mixing 100 parts of water and 6-10 parts of polyvinyl alcohol. The heat conductivity coefficient of the heat-insulating material is only 0.036; the heat-insulating material has the advantages of favorable heat-insulating property, high binding strength, high acid / alkali corrosion resistance and high weather resistance; the volcanic ash raw material has abundant sources, so the cost is lower; and therefore the heat-insulating material disclosed by the invention can substitute the traditional heat-insulating material, and has unique advantages in the application field of architectural coating for 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 ...

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.
