Manufacturing method of composite plate

Abstract

The invention provides a manufacturing method of a composite board, comprising the following steps: hot-pressing straws into straw boards for use; uniformly coating hot-melt adhesive on both sides of the straw boards; covering the hot-melt adhesive with metal mesh; entering into a roller press, Heating to 180-220°C and rolling repeatedly, the number of times of rolling is not less than 3 times; the outer layer of metal mesh and hot melt adhesive is coated with adhesive, and the outer layer of adhesive is covered with fiberboard; the outer layer of fiberboard is coated with adhesive , and then cover the wooden board, rolling without heating, and the number of rolling is not less than 3 times; the outer layer of the wooden board is painted and dried. The invention can effectively improve the load-bearing capacity of the board, avoid the expansion and deformation of the composite board, enhance the toughness of the board, can replace the pure solid wood board, reduce the deformation probability of the board while maintaining the load-bearing performance of the board, gradually reduce the usage of the solid wood board, and protect the environment .

Description

technical field [0001] The invention relates to the field of plate manufacturing methods, in particular to a manufacturing method of a composite plate. Background technique [0002] In the process of making steel-wood furniture, the amount of boards used is high and the cost investment is large. However, due to the high load-bearing effect in furniture production and the need to prevent deformation of the boards, expensive boards such as solid wood are often used in production. Solid wood boards are increasingly scarce, and overexploitation of forests will cause great harm to the environment. How to manufacture composite boards to replace solid wood boards and reduce the deformation probability of boards while maintaining the load-bearing performance of the boards has become an urgent problem to be solved. Contents of the invention [0003] In order to overcome the shortcomings of the existing plate manufacturing methods, the invention provides a composite plate manufactu...
