摘要
A wood veneer laminated gypsum board comprises a gypsum core and lamination of a paper or a paper-like outer layer on both sides, an aluminum backed wood veneer bonded to the paper outer layer, and debossed designs on the wood veneer which penetrates beyond the surface of the gypsum board. The wood veneer laminated gypsum board is formed by spraying or applying a mixture of adhesive diluted with liquid softening agent, which may include water or water mixed with other materials, on the aluminum side of the aluminum-backed wood veneer. The paper or paper-like outer covering is lightly sprayed or coated with the softening agent. The coated aluminum backed wood veneer is placed on the lightly coated the gypsum board. The wood veneer is moistened with water. The wood veneer and the gypsum board is pressed with application of heat for a predetermined period.
