Abstract

The invention relates to a building exterior-wall thermal-insulation material obtained by a combined manufacturing method and the combined manufacturing method. Raw materials of the building exterior-wall thermal-insulation material comprise an aggregate, a high-temperature binder and a low-temperature binder. The aggregate comprises expanded perlite, expanded vermiculite, pumice, expanded clay, expanded shale, expanded volcanic ash and expanded raw materials having a large amount of pores. The high-temperature binder comprises 45-60wt% of SiO2, 4-8wt% of Al2O3, 10-15wt% of CaO, 5-12wt% of B2O3, 1-8wt% of Na2O, 1-8wt% of K2O and 1-4wt% of ZnO. The low-temperature binder comprises water glass and bentonite. The combined manufacturing method has the characteristics that 1, in plate manufacture, the size and deformation can be controlled easily and the building exterior-wall thermal-insulation material is superior to foam light thermal-insulation materials; 2, compared with the foam thermal-insulation material manufacturing method utilizing a series of technological parameters such as a sintering temperature to control a heat conduction coefficient, the combined manufacturing method provided by the invention realizes heat conduction coefficient control only by raw material selection; 3, a sintering temperature is controlled in a range of 700-900 DEG C; and 4, in plate production, a roller kiln direct firing technology is utilized and kiln tools such as a base plate and a saggar are avoided so that a sintering heat utilization rate is high.

Description

1. Technical field [0001] The invention relates to a combination method for manufacturing building exterior wall insulation materials and a manufacturing method thereof, in particular to a combination method for producing A-level inorganic non-metallic materials used for building exterior wall insulation. 2. Background technology [0002] From the perspective of social energy consumption structure, the world's building energy consumption has reached about 1 / 3 of the total energy consumption; it will gradually increase with the improvement of people's living standards. Among all building energy consumption, the energy consumption of building envelope accounts for a large proportion. The outer wall area accounts for most of the enclosure structure. Therefore, the thermal insulation technology of the outer wall has a great relationship with the reduction of building energy consumption and the improvement of indoor comfort. The basis of exterior wall insulation technology is th...
