Preparation method of high performance composite sheet material and high performance composite sheet material

Abstract

The invention discloses a preparation method of high performance composite sheet material, and the composite sheet material is prepared by preparation of melamine dipping veneer and tight adhesion of wood-based plate and original board. Original veneers or technical veneer materials are impregnated in to a reaction tank containing melamine resin and benzaldehyde, and are dried after completing impregnation, and cut into needed dimensions; the impregnated original veneers or technical veneer are stacked with brown papers or common veneers together, and the materials are pressed together at a high temperature, and then the melamine dipping veneer composite board is formed. The high performance composite sheet material dipping surface layer is polished or directly coated with a toning paint and a waterproof wear resistant surface paint, and the surface treatment improves appearance effect and performance. The toning paint treatment may not be applied, and common surface paints may be coated for realization of surface treatment or the surface paint is not coated. The invention also discloses a high performance composite board with water resistance, heat resistance, arc resistance and excellent flame resistance.

Description

technical field [0001] The invention relates to the technical field of furniture design and manufacture, in particular to a method for preparing a high-performance composite board, and more particularly to a high-performance composite board for realizing the method. Background technique [0002] Melamine is an important organic chemical intermediate product, mainly used to make melamine resin, which has excellent water resistance, heat resistance, arc resistance and excellent flame retardancy. It can be used in the production of decorative boards, used in amino plastics, adhesives, coatings, currency paper strengthening agents, textile auxiliaries, etc. [0003] In the prior art, wooden boards are produced by sticking veneer, but the production process is complicated, and multiple subsequent painting steps are required, the production cost is high, it is not conducive to environmental protection, and the wear resistance is not good. The traditional melamine-impregnated film...

AI Technical Summary

Problems solved by technology

[0005] Although the method disclosed in the above-mentioned patented technology controls the cost of the product, considering that the application of general plates not only needs to consider the wear resistance of the product, but also any defects in functions such as anti-corrosion, fire prevention, waterproof, anti-scratch, etc. will affect For the application of boards, of course, the product structure has strong adhesion, and no faults will fall off, which is only the most basic quality assurance for board applications.

Therefore, the patented technology disclosed in the above patent still solves some of the above problems, but in the application of the product, there is no outstanding advantage, including no clear improvement in terms of convenience and performance of use.
