Abstract
The invention relates to a sandwich construction type heat retaining plate and manufacturing technique of the sandwich construction type heat retaining plate. The sandwich construction type heat retaining plate comprises two layers of face plates, a heat retaining layer is clamped between the two layers of face plates, and a plurality of through holes are arranged in the heat retaining layer. Connecting columns with two ends respectively connected with the two layers of face plates in a fixed mode are inserted in the through holes, and the two layers of face plates and the connecting columns are all made of inorganic bond materials. According to the sandwich construction type heat retaining plate and the manufacturing technique of the sandwich construction type heat retaining plate, a plurality of connecting columns are arranged between the two layers of face plates so as to play a supporting role in the heat retaining layer. When face plates of the sandwich construction type heat retaining plate are under large pressure, the connecting columns are capable of guaranteeing that the heat retaining layer does not deform under the condition that the heat retaining effect of the sandwich construction type heat retaining plate is good. The face plates do not deform or craze with the deformation of the heat retaining layer, so that the service life of the sandwich construction type heat retaining plate is prolonged. Besides, fire resistance of the sandwich construction type heat retaining plate can be improved due to the fact that the inorganic bond materials are adopted, and buildings are effectively prevented from bursting into flames.
Description
technical field [0001] The invention relates to a building thermal insulation material, in particular to a sandwich structure thermal insulation board and a production process thereof. Background technique [0002] Existing thermal insulation boards installed on walls for thermal insulation of buildings are generally divided into two types, one is to have EPS (polystyrene foam, English full name Expanded Polystyrene) board with cement mortar directly outside the wall Inorganic material plastering is applied on the exterior wall by adhesive paste, and it is directly used for heat preservation. This structure has weak compressive resistance, and the surface inorganic material plastering layer is prone to deformation and cracks, and the fireproof effect is poor; the other is EPS The two sides of the board are respectively glued to the upper and lower panels, which are used in the semi-hanging or hanging external wall insulation system. The structure of this insulation board has...
