Problems solved by technology

Facing the specific implementation of this requirement and standard, the current thermal insulation exterior wall system, polystyrene board and compact board will face practical problems in technology and construction: the thermal conductivity of polystyrene board is 0.04w / m·k, The thermal conductivity of the dense board is 0.027-0.029w / m·k. Although the thermal conductivity of the dense board is good, its wind resistance value cannot withstand the high-rise buildings.
The first problem that arises is that the cement polystyrene mortar on both sides cannot be firmly combined with the polystyrene board, which is easy to cause falling off
In addition, the wall is an inorganic substance, and the cement polyphenylene mortar is an organic substance. The inorganic and organic substances cannot be combined well. Once it falls off, it will cause casualties and pose a great safety hazard.

Abstract

The present invention discloses one kind of heat insulating material for outer wall of building and its application process. The heat insulating material is prepared with expanded perlite in 55-65 weight portions, polystyrene grain in 1.5-3.5 weight portions and acidified magnesia as heat insulating material additive in 35-45 weight portions. Experiment shows that present invention as one kind of excellent outer wall heat insulating material has low heat conducting coefficient, high weather resistance, high tensile strength, high wind resistance and high impact strength.

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. The outdoor temperature in Northeast China is -45°C to -20°C in winter, and the wall temperature in South China can reach a maximum of 70°C to 75°C in summ...
