Problems solved by technology

In decoration, the pursuit of wood products has undergone a huge change from practicality to individualization and functionality. The existing particleboard processing technology is difficult to achieve the unity of functionality and individualization. For example, increasing the color of particleboard requires Dye the particle board; increase the water resistance of the particle board is mainly to add water repellents such as paraffin; increase the anti-corrosion performance needs to increase the preservative; increase the anti-mold performance requires anti-mold agent; in process

Abstract

The invention relates to complexed shavings and a complexed shaving board and manufacture methods thereof, and belongs to the technical field of processing of artificial boards. The complexed shavingboard is composed of the complexed shavings and an adhesive, a plant polyphenol metal salt complex is introduced into the complexed shavings, and metal ions are fixed on the surface of the shavings and in cell walls, cell cavities and / or cell gaps, so that not only can the color of the shaving board be changed effectively, but also the waterproof performance, corrosion resistance, mildew resistance and other properties of the shaving board can be increased.

Description

technical field [0001] The invention relates to the technical field of wood-based board processing, in particular to a complexed particle board, a complexed particle board and a manufacturing method thereof. Background technique [0002] Particleboard, also known as particle board, is made of wood or other wooden materials after shavings are applied, and then glued together under heat and pressure to form a wood composite material. Due to its good physical and mechanical properties and easy processing, it has been widely used in the fields of panel furniture, building structural materials, and decorative materials. With the continuous development of particleboard in the field of home decoration, and people's continuous pursuit of a better life. In decoration, the pursuit of wood products has undergone a huge change from practicality to individualization and functionality. The existing particleboard processing technology is difficult to achieve the unity of functionality and...
