Abstract

The invention discloses a thermal insulation material for a house building. The thermal insulation material is prepared from the following ingredients in parts by weight: 40-57 parts of sand, 20-37 parts of pulverized fuel ash, 2-5 parts of heavy calcium powder, 0.1-0.2 part of hydroxypropyl methyl cellulose, 0.3-0.6 part of rubber powder, 0.15-0.3 part of wood fiber, 0.1-0.2 part of polypropylenefiber, 0.1-0.2 part of polyvinyl alcohol, 0.05-0.1 part of modified polyethylene oxide and 10-15 parts of water. According to the thermal insulation material, the physical and mechanical properties are stable, the shrinking percentage is low, the shrinkage crack can be resisted, meanwhile, the flame retardant property is good, and the heat conductivity coefficient is small.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a building thermal insulation material. Background technique [0002] With the development of the construction industry, building materials such as thermal insulation, heat insulation, and flame retardant have attracted more and more attention and attention, especially after several catastrophic fires across the country have brought unpredictable After the loss, the country and people once attached great importance to building materials. At present, building insulation materials are also widely used in the construction industry. However, building insulation materials have been in a state of being developed, and there are some following problems. [0003] Building insulation materials have problems such as poor flame retardancy, large thermal conductivity, and easy cracking. In actual use, there are hidden dangers. In order to solve the above problems...
