Three-layer type heat insulation decoration composite panel

Abstract

The invention relates to a three-layer heat-preservation decoration composite plate which comprises a surface layer, an intermediate layer and a bottom layer; the surface layer is the decoration plate layer; the intermediate layer is the polyurethane foam colloid layer; the bottom layer is the foam material layer; the decoration plate layer is adhered tightly to the foam material layer through the polyurethane foam colloid layer to construct the three-layer heat-preservation decoration composite plate. A connecting piece is arranged on the back surface of the composite plate; the connecting piece is threaded through the intermediate layer and the bottom layer; the inner end of the connecting end is adhered to the inner side of the surface layer through strong adhesive; the outer end of the connecting piece is provided with a metal hanging piece; a screw is arranged on the metal hanging piece; the three-layer heat-preservation decoration composite plate can be applied in constructions, so as to reduce the construction load, shorten the construction period and save labor resources; in the heat-preservation decoration composite plate, the intermediate layer is fixed with the bottom layer and the connecting piece is mounted; the connecting piece is reinforced and fixed through the adhesion with the foam colloid layer so that the effect of double-layer fixation is realized; the connecting is adopted to enable the surface plate to be directly fixed on the wall body; the heat-preservation decoration composite plate is high-temperature resistant, has no deformation and good heat-preservation property.

Description

technical field [0001] The invention relates to a building board, in particular to a three-layer thermal insulation and decorative composite board. technical background [0002] Existing thermal insulation wallboards have two types of bonding technology and foaming technology. Adhesive technology refers to the use of adhesives to bond the decorative panel to the insulation board, such as expanded polystyrene-EPS, extruded polystyrene-XPS, vegetable oil polyurethane rigid foam-PU board, due to the unstable quality of the adhesive, Or the workers did not operate properly, so the bonding quality is not good, and the decorative panel will fall off when the hand is lightly peeled off, and the combination of expanded polystyrene-EPS and extruded polystyrene-XPS and metal finishes, when the temperature reaches 70 ℃, the insulation material will melt and deform, resulting in deformation of the entire insulation board; foaming technology refers to spraying or pouring foaming adhesiv...
