Abstract

The invention discloses a production method of recombined bamboos subjected to resinifying surface treatment. The method comprises the following steps: (1) preparing raw materials; (2) drying; (3) preparing an adhesive; (4) gumming and resinifying; (5) drying; (6) assembling; (7) performing hot press forming; (8) thermally stacking; (9) trimming. According to the steps, the bamboo raw materials are subjected to immersion treatment by high-content phenolic resin, the recombined bamboos are formed by a one-time hot pressing process, the resinified recombined bamboos have the performances of wear resistance, heat resistance, water resistance, chemical pollution resistance and the like without surface treatment, and the production process is relatively simple and convenient as compared with a conventional method, so that the added value of the recombined bamboos can be greatly increased, the application range of the recombined bamboos can be expanded, and the recombined bamboos can be widely applied to the industries of furniture, buildings and the like.

Description

Technical field [0001] The invention relates to the field technology of wood-based panels in the direction of wood science and technology in forestry engineering, in particular to a method for making resinized surface-treated recombinant bamboo. Background technique [0002] Reconstituted bamboo has excellent physical and mechanical properties such as high strength, small deformation, good rigidity, and high nail holding force, and can be widely used in many fields. For example, using the characteristics of high strength, high hardness, and good dimensional stability of reconstituted bamboo, it can be used as a container floor. The reorganized bamboo is processed by sawing, planing, milling, tenoning, drilling, drilling, sanding and surface decoration, etc., and can be made into reorganized bamboo furniture of various types and structures. [0003] In the process of using reconstituted bamboo, surface treatment technology is involved. Common methods for surface treatment of wood-...
