Cement porous polymer composite heat insulation plate

Abstract

The invention relates to a cement porous polymer composite heat insulation plate. The cement porous polymer composite heat insulation plate is characterized by comprising an efficient heat insulation layer, a three-dimensional rigid skeleton and a cement concrete layer using a porous polymer as light aggregate, wherein the three-dimensional rigid skeleton is connected between the cement concrete layer and the efficient heat insulation layer and respectively embedded into the cement concrete layer and the efficient heat insulation layer so as to form an integrated plate member. The heat insulation performance of the integrated plate member can be promoted, the mechanical strength of the integrated plate member can be improved, the surface density and the weight of the integrated plate member are reduced, and meanwhile, the requirements of fireproof, shockproof, durable and wall rendering construction are met; and moreover, punching shear resistance and bending resistance of the integrated plate member can be improved, and the mechanical property required by template engineering is met.

Description

technical field [0001] The invention relates to a cement porous polymer composite insulation board. Background technique [0002] Existing external thermal insulation measures for external walls of buildings usually first hang and paste porous polymers on the external walls as the thermal insulation layer, and then thinly plaster the external thermal insulation layer, which not only has serious fire hazards, but also has low strength, poor durability, and easy external finishes. Cracking and falling off cause leakage, which not only affects residential use, but also reduces the service life of the building. Therefore, the current building exterior wall insulation, especially the energy-saving renovation of existing building exterior walls, urgently needs a non-flexible, fireproof, impermeable, durable, and easy-to-construct lightweight insulation board. [0003] On the other hand, with the development of the petrochemical industry, a large amount of waste of porous polymer ...
