Abstract

The invention discloses a heat-insulating material which comprises the following raw materials in parts by mass: 10-25 parts of volcanic ash and 75-90 parts of 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 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. 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 thermal insulation materials on the market generally have hidden dangers such as large specific gravity, high thermal conductivity, poor bonding performance, and easy falling off. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a thermal insulation material with remarkable thermal insulation effect, light specific gravity, acid and alkal...
