Inorganic composite polystyrene non-combustible thermal insulation sandwich panel prefabricated wall

Abstract

This application is an assembled wall of inorganic composite polystyrene non-combustible thermal insulation sandwich panels, including: outer panels clamped on both sides of the wall; thermal insulation sandwich panels in the center of the wall; flexible glue between the outer panels and thermal insulation sandwich panels Adhesive layer; the flexible adhesive layer is made of crushable foam, fiber and polyurethane glue mixed together; the thermal conductivity of the thermal insulation sandwich panel is 0.042-0.050. The outer panel is a color steel plate or a silicon calcium plate. The thermal insulation sandwich panel is an inorganic composite polystyrene non-combustible thermal insulation sandwich panel. The calcium silicate board is mixed with fly ash. The fibers are any one or more of polypropylene fibers, TPFE fibers or glass fibers mixed in any proportion. The main advantage of this application comes from the crushable foam in the adhesive layer. This design makes the polyurethane glue better distributed between the outer layer and the core material. After the material is molded and kept under pressure for six hours, the polyurethane produces negative pressure microbubbles between the crushable foam and the fiber, and these microbubbles can improve the bonding force between the materials and make the structure of the application more stable.

Description

Technical field: [0001] The application belongs to the field of building materials, and specifically relates to an assembled wall made of inorganic composite polystyrene non-combustible heat-insulating sandwich panels. Background technique: [0002] The existing prefabricated wall structure comprises an outer plate, an insulating layer sandwiched between the outer plates and an adhesive layer bonding the two. In the prior art, the bonding between the insulation layer and the outer plate is not reliable, and cracks and hollows often occur. At the same time, due to the inevitable force distortion of the wall, it is more likely to cause the bond to fall off; these unreliable factors all have no small hidden dangers to the safety of personnel and property during the production, transportation and use of the wall. [0003] At the same time, the flame resistance and flame retardancy of each layer of the wall structure also need to be continuously improved and improved. Inventio...

In the prior art, the bonding between the insulation layer and the outer panel is not reliable, and cracks and hollowing often occur

At the same time, due to the unavoidable force distortion of the wall, it is more likely to cause the bond to fall off; these unreliable factors all have great hidden dangers to the safety of personnel and property during the production, transportation and use of the wall.
