Building decoration plywood

Abstract

The invention discloses building decoration plywood which comprises a plywood body. The plywood body comprises a metal bottom plate, a first polyurethane woodworking adhesive layer is arranged at thetop of the metal bottom plate, a first heat insulation plate is arranged at the top of the first polyurethane woodworking adhesive layer, a second polyurethane woodworking adhesive layer is arranged at the top of the first heat insulation plate, a ceramic core plate is arranged at the top of the second polyurethane woodworking adhesive layer, a third polyurethane woodworking adhesive layer is arranged at the top of the ceramic core plate, a second heat insulation plate is arranged at the top of the third polyurethane woodworking adhesive layer, and a fourth polyurethane woodworking adhesive layer is arranged at the top of the second heat insulation plate. Epoxy resin plates are arranged on two sides of the plywood, loss of moisture in the plywood can be decreased, a good buffering functioncan be achieved when the plywood and other objects are collided, and the plywood is reinforced and cannot be easily damaged.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a plywood for building decoration. Background technique [0002] Plywood is one of the commonly used materials for furniture and one of the three major boards of wood-based panels. A group of veneers are usually assembled and glued together according to the direction of the wood grain of adjacent layers perpendicular to each other. Usually, the surface board and inner layer board are symmetrically arranged on both sides of the center layer or core. The slab made of the veneer after gluing is criss-crossed according to the direction of wood grain, and pressed under heating or non-heating conditions. The number of layers is generally an odd number, and a few have even numbers. The difference in physical and mechanical properties in the vertical and horizontal directions is small. The commonly used types of plywood are three-ply board, five-ply board and so on. Plywo...

Problems solved by technology

However, the existing plywood has simple structure and single function. Because the outer surface area is relatively large around the plywood, the water evaporates more easily, so that the four corners of the plywood first appear glue layer cracks, and the corners of the plywood are easy to be bumped and cracked, shortening The service life of plywood used in construction
