Description

technical field

[0001] The invention relates to a building material, in particular to a thermal insulation material for building exterior walls and a preparation method thereof, belonging to the field of building materials. Background technique

[0002] At present, the thermal insulation materials using polystyrene board, dense polystyrene board and thermal insulation mortar (cement mixed with polystyrene particles) in the thermal insulation market all have their own insurmountable defects and unsatisfactory parts in technology.

[0003] Polystyrene board is an organic material extracted from petroleum. Sensitive to the influence of temperature, the molecular activity is very active. The heat-resistant temperature is only 70°C, and the dimensional change rate reaches 5% after 48 hours at 70°C as measured by experiments. In Northeast China, the outdoor temperature in winter is -45°C to 20°C, and in the south, the wall surface temperature can reach a maximum of 70°C to 75°C ...
