High-carbon preservative bamboo wallboard and production method

Abstract

The invention discloses a high-carbon preservative bamboo wallboard production method, which comprises the steps of (1) removing tabasheer from a fresh bamboo and rolling the bamboo to obtain a silky bamboo splint; (2) drying the bamboo splint until the water content is lower than 6-9%; (3) carbonizing the bamboo splint that meets the water content requirement in a carbonization chamber at normal pressure, and selecting qualified and removing the unqualified bamboo splint after carbonization; (4) processing the qualified carbonized bamboo splint by impregnation, and drying the bamboo splint until the water content is between 13-17% after processing; and (5) processing the bamboo splint for health preserving and balancing in a health preserving room; (6) performing hot pressing moulding to obtain a bamboo sheet; (7) processing the bamboo sheet to obtain the bamboo wallboard. The invention also relates to a bamboo wallboard obtained by the above method. The bamboo preservative performance of the bamboo wallboard can be greatly improved by carbonization; the production period is short; the operation is simple; the appearance quality is high; and advantages like safety and environmental protection are provided.

Description

technical field [0001] The invention relates to a bamboo wallboard and a production method thereof, in particular to a high-carbon anti-corrosion bamboo wallboard and a production method thereof. Background technique [0002] The traditional processing method of bamboo wallboard is: take moso bamboo and break it into bamboo shreds or bamboo slices, after drying, dip it into a mold, then press and solidify it under high pressure, and process it into bamboo wallboard. Although the traditional production technology is relatively mature, However, the anti-corrosion performance of the product is not very satisfactory. In order to improve the anti-corrosion performance of bamboo wall panels, the current domestic common practice is to carry out two dipping processes to slow down the rot process of bamboo wall panels through glue sealing. This method not only increases production Cost, increase production intensity, can bring a series of environmental protection problems again, the ...

Problems solved by technology

[0002] The traditional processing method of bamboo wallboard is: take moso bamboo and break it into bamboo shreds or bamboo slices, after drying, dip it into a mold, then press and solidify it under high pressure, and process it into bamboo wallboard. Although the traditional production technology is relatively mature, However, the anti-corrosion performance of the product is not very satisfactory. In order to improve the anti-corrosion performance of bamboo wall panels, the current domestic common practice is to carry out two dipping processes to slow down the rot process of bamboo wall panels through glue sealing. This method not only increases production cost, increase the production intensity, and will bring a series of environmental protection problems, the most important thing is that the anti-corrosion performance of the bamboo wall panels produced by this method is only slightly improved, and the anti-corrosion performance of the bamboo wall panels cannot be greatly improved.

[0003] At present, another means to improve the anticorrosion performance of bamboo wall panels is the high-temperature carbonization process, such as: CN1970259A discloses a production method of bamboo boards, which introduces a carbonization process in the production method, so that the bamboo boards made have uniform density and static High bending strength, high hardness, wear resistance, no mildew, good stability, and not easy to deform. However, before the carbonization of the bamboo chips, the bleaching process is carried out first. The main function of the bleaching process is to increase the antiseptic performance of the bamboo. Bamboo is not prone to mold and insects. It can be seen that the carbonization process in this method is combined with the bleaching process to achieve antiseptic effect, and the bamboo produced by the bleaching process has a matte color, which affects the appearance quality of the bamboo. In addition, the bamboo is bleached for a period of time. There will be chlorine smell in it, which will seriously affect human health

[0004] CN1876343A discloses a high-temperature hydrothermal treatment method for wood. The invention can improve the dimensional stability, corrosion resistance and weather resistance of wood through high-temperature hydrothermal treatment of wood, so that the treated wood can be widely used in humidity and temperature. In the environment with relatively large changes, but the disadvantage of this invention is that the heat treatment process is complicated. After high-temperature treatment, it is necessary to wait until the temperature drops below 100°C before the wood can be treated with steam or hot water, and each carbonization process in the carbonization furnace Both need to control the moisture content of wood, the operation is complicated, and finally need to be balanced in the atmospheric environment for more than 15 days, resulting in a long cycle of the entire high-temperature hydrothermal treatment process, which is not conducive to actual production
