Zero-pollution glue-free bamboo and/or wooden recombined material and manufacturing method thereof

Abstract

The invention provides a pollution-free non-adhesive bamboo and / or wood reconstructed material which comprises a plurality of unit bodies with set lengths. The unit bodies are connected into a whole through connecting structures to form the reconstructed material. The reconstructed material can be expanded in the horizontal direction and the longitudinal direction through the connecting structures. The invention provides a manufacturing method which comprises the steps of manufacturing of the unit bodies, molding and assembling, manufacturing of the molded material, manufacturing of the reconstructed material and the like, and the finished pollution-free non-adhesive reconstructed material is obtained after material maintenance and surface green treatment. The reconstructed material has no pollution or adhesives and is friendly to environment; internal stress of the material can be adjusted, so that the cracking phenomenon is avoided; the reconstructed material can be applied to the fields of building beam columns, structural members, furniture and decoration materials. By means of the manufacturing method, the reconstructed material without pollution and adhesives can be manufactured, and chemical pollution in the processing process of the reconstructed material is eliminated.

Description

technical field [0001] The invention belongs to the technical field of recombined materials, relates to adhesive-free, environment-friendly and resource-saving structural materials, and in particular provides a zero-pollution, non-adhesive bamboo and / or wood recombined material and a manufacturing method thereof. Background technique [0002] my country is the country with the most abundant bamboo resources in the world. In recent years, with the gradual scarcity of timber resources in the world, it is becoming more and more important to use timber and bamboo resources rationally and effectively. [0003] One way to rationally utilize bamboo and wood materials is material recombination and compounding. [0004] In the prior art, the main recombinant bamboo technologies used in fields such as construction and decoration are: [0005] (1) Bamboo strip recombination technology: processing bamboo into thick bamboo strips, alone, or combined with combed wood beams, appropriate ...

AI Technical Summary

Problems solved by technology

[0014] (2) Toxic substances such as benzene in the paint volatilize

[0016] (3) The hazards of VOCs total volatile organic compounds

[0018] (4) Pollution in the production process

[0023] (2) The processing technology of bamboo industry is relatively weak, which is a labor-intensive industry

[0024] (3) No corresponding production process for glue-free recombination connection has been developed

[0025] In addition, the existing glued bamboo materials also have the disadvantage of being easy to crack. During use, the existing bamboo materials require a certain humidity in the environment. If the air is too dry, the materials are prone to cracking, which affects the use.

Therefore, the existing glued bamboo materials are generally suitable for use in the south with high humidity, and the air in the north is dry, which limits the use of bamboo materials to a certain extent.

[0026] The wooden recombined materials in the prior art also have pollution hazards such as adhesives, and a large amount of adhesives are also used to reassemble large recombined wood by splicing small pieces of wood, and the product and production process will also cause pollution to the environment.
