Non-painting veneer composite board prepared under condition of low temperature and low pressure

Abstract

The invention discloses a non-painting veneer composite board prepared under the condition of low temperature and low pressure, which relates to a composite board and can overcome the problems that the painting treatment of the existing laminated wood board in the decorating process and in the furniture production process causes the secondary pollution; and melamine woodgrained paper fixed on a surface decorated wood-based panel with paper impregnated thermosetting resins can be better glued with the panel surface of the wood-based panel only under the condition of high temperature and high pressure. The non-painting veneer composite board of the invention comprises a substrate and a melamine impregnated woodgrained paper layer. One side of the substrate is laminated and fixed with the melamine impregnated woodgrained paper layer into one body. The melamine impregnated woodgrained paper layer is implemented by adopting a melamine adhesive for low-temperature curing and impregnation tocure and impregnate the woodgrained paper under the condition of low temperature and low pressure. The condition of low temperature and low pressure is the processing condition that a temperature is between 120 and 130 DEG C and a unit pressure is 1.0MPa. The melamine impregnated woodgrained paper layer is adhered on the surface of the substrate. After the melamine impregnated woodgrained paper layer is cured, no any harmful substances such as VOC and the like are released. The non-painting veneer composite board prepared under the condition of low temperature and low pressure is used for home decoration and furniture production.

Description

technical field [0001] The invention relates to a composite plate. Background technique [0002] Due to the increasing shortage of wood, the price of pure solid wood is relatively expensive, and the substitutes of pure solid wood wood are gradually filling the market, such as blockboard, blockboard MDF and impregnated film paper veneer wood-based panels. However, each board has its own disadvantages. Among them, when the blockboard is used for decoration, it needs to be sprayed with paint, which is easy to cause indoor air pollution; because the blockboard density board contains density boards in its composition, it is difficult to meet the requirements of interior decoration for water resistance and environmental protection; Adhesive paper-faced wood-based panels have the defects of high density, bulkiness, poor moisture resistance and poor processing performance. In addition, the melamine wood grain paper fixed on the film-coated paper-faced wood-based panels can only be ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the secondary pollution caused by the paint spraying treatment of existing blockboards in the decoration and furniture production process. To solve the problem that it can be better glued to the wood-based panel surface, a paint-free veneer composite panel made under low temperature and low pressure conditions is provided.
