Manufacturing method of composite board

Abstract

The invention provides a manufacturing method of a composite board. The manufacturing method comprises the following steps: processing straw into a straw board for later use through hot-press molding; uniformly coating the two surfaces of the straw board with a hot-melt adhesive; covering the hot-melt adhesive with metal nets; entering a roller press, heating to 180-220 DEG C, and repeatedly carrying out roller pressing for not less than three times; coating the outer layers of the metal nets and the hot-melt adhesive with a bonding agent, and covering the outer layer of the bonding agent with fiber boards; coating the outer layers of the fiber boards with a bonding agent, covering the bonding agent with wood boards, keeping the temperature, and carrying out roller pressing for not less than three times; and coating the outer layers of the wood boards with paint and drying the paint. The bearing force of the board can be effectively increased, the expansion deformation of the composite board is avoided, the tenacity of the board is enhanced, and a pure solid board material can be replaced. The deformation probability of the board material is reduced under the condition of keeping the bearing performance of the board material, the usage of the solid board material is gradually reduced, and the environment is protected.

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...
