Abstract

The invention discloses a self-insulation wall material. The self-insulation wall material comprising the following components in proportion: 30-90 parts by weight of high-performance cement or high-efficiency concrete admixture, 5-40 parts by weight of aggregate, 0.1-5 parts by weight of air entraining agent, 0-8 parts by weight of expanding agent, 0-2 parts by weight of waterproof agent, and 0-20 parts by weight of anti-crack fiber. The self-insulation wall material disclosed by the invention has thermal insulation and insulating performance similar to that of the organic insulation material, the strength of a material which can be used as a building enclosure, as well as the comprehensive performances of uniform and single material, convenience in construction, good durability, good fireproof and waterproof performance, resistance to deformation, and non-crack and non-leakage; and the invention provides an appropriate self-insulation material for saving more than 50% and 65% of building energy.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a self-insulating wall material. Background technique [0002] my country's building energy consumption accounts for 30-40% of the country's total energy consumption, seriously affecting the national energy conservation and carbon reduction goals and the country's sustainable development. Reducing building energy consumption and saving energy is the main obligation from the national government to the common people at present and in the future. For this reason, the state has put forward the mandatory standard requirements that building energy conservation must reach 50% and 65%. The building envelope is the main body of building heat exchange, and the energy consumed through the building envelope accounts for the majority of building energy consumption. Therefore, the thermal insulation performance of building envelope materials is particularly important in building energy cons...
