Abstract

The invention relates to an insulation sound-absorbing decorative plate and a preparation method, which belongs to the technical field of building material. The insulation sound-absorbing decorative plate comprises a substrate, a superficial layer and a bottom layer; the substrate is spliced with the superficial layer through PUR glue, the other surface of the substrate is spliced to the bottom layer; the materials of the substrate are PP fiber and glass fiber; the material of the superficial layer is a PP membrane, or a PVC membrane, or a PETG membrane; and the material of the bottom layer is non-woven fabrics. The preparation method comprises the following steps: 1)mixing the PP fiber and glass fiber, using an air laying method to prepare an original substrate; 2)taking the non-woven fabrics as the bottom layer, compacting one side of the original substrate and the bottom layer by a veneer press under the temperature of 180-220 DEG C to prepare a double-layer plate; 3)performing corona treatment and preheating the substrate surface of the double-layer plate, then coating the PUR glue; and 4)applying the superficial layer and the substrate of the double-layer plate together. The insulation sound-absorbing decorative plate does not contain asbestos, benzene and formaldehyde which are harmful to human body, light pollution of a matte series product can be avoided, and the production technology enables environmental protection.
