Description

technical field [0001] The invention relates to a building thermal insulation material, in particular to an anti-seepage bonding material for an expanded perlite external wall thermal insulation board and a preparation method thereof. Background technique [0002] Building energy conservation is an industry supported by the national industrial policy. At present, building energy-saving materials are mainly divided into inorganic thermal insulation lightweight aggregate and organic thermal insulation lightweight aggregate. However, due to the characteristics of the chemical properties of materials, no matter whether it is an inorganic system or an organic system, it is impossible to simultaneously meet the requirements of heat preservation, energy saving and fire safety. In terms of thermal insulation performance, organic materials are superior to inorganic materials; in terms of fire safety performance, inorganic thermal insulation materials are slightly better. In recent ...
