Composite insulating brick

Abstract

The invention discloses a composite insulating brick. The insulating brick comprises an insulating core layer and a fireproof insulating mortar layer covering an outer layer of the insulating core layer. During production and manufacture, the conventional insulating core layer is mixed, burdened, pressed and molded, and the fireproof insulating mortar layer is prefabricated, compounded and molded on a production line of the insulating core layer. The defects in the prior art are overcome, effective flame retardance can be effectively realized, the material is light in weight, low in heat-conducting property and low in water absorption rate, the adhesive force between the brick and the wall surface and adhesion force between the brick and the surface decoration layer are improved, the tensile strength meets the exterior wall decoration requirement, and the process is simple and convenient to control.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite thermal insulation brick. Background technique [0002] Most of the existing thermal insulation boards are cement foam boards, although they are non-combustible, but their tensile strength is difficult to meet the requirements of pasting decorative bricks on external walls. Foam glass boards and ceramic foam boards are excellent insulation materials in terms of strength, durability, and combustion performance. However, their production scale is generally limited, with few raw materials and high energy consumption. Large pollution and high cost restrict their popularization and application. Contents of the invention [0003] The purpose of the present invention is to provide a composite thermal insulation brick, which overcomes the deficiencies of the prior art, can be effectively flame-retardant, has light material quality, low thermal conductivity, and ...
