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.
This will inevitably lead to the disadvantages of cumbersome construction, insufficient wind pressure resistance, and unsafe use on high-rise buildings.

Abstract

The present invention discloses one kind of heat insulating brick and its production process. The heat insulating brick is produced with the materials, including expanded perlite or polystyrene grain in 0.5-5 weight portions and acidified magnesia as heat insulating material additive in 1-20 weight portions, and through mixing, adding water in 0.8-1 time of the mixture weight, pressing to form, and drying. The no-baking brick is one kind of excellent heat insulating building material possessing compression strength of 2.7-5.6 MPs, heat conducting coefficient of 0.07-0.1 w / m.k or 8 times lower than that of common brick, sound isolating effect and fireproofing.

Description

technical field [0001] The invention relates to a building material, in particular to an insulating brick for building 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 in summer. The polystyre...
