Problems solved by technology

However, since the hardest bamboo green on the bamboo material is removed during the preparation of the bamboo mat, and the surface layer of the shaped material is opposite to the original surface layer of the original bamboo, the surface layer of the bamboo mat is relatively hard, and it is solidified into a bamboo mat after high pressure. The profile, the internal stress of the plate is large, and the profile will be deformed due to the internal stress after a long time, which needs to be solved urgently

Abstract

The invention discloses a preparation method of a bamboo mat not prone to deformation. The method comprises the following steps: S1, carrying out carbonization treatment of a pretreated bamboo, then feeding the bamboo into a hot press and flattening the bamboo to obtain the carbonized bamboo, wherein the carbonization treatment is characterized by feeding the bamboo into a drying and disinfectingcarbon dryer, the heating temperature of the drying and disinfecting carbon dryer is 160-190 DEG C, the heating time is 2-4 hours, and the bamboo is carbonized at a carbonization degree of 5-30%; andS2, feeding the carbonized bamboo into an ethanol solution, adding soyabean lecithin and tetraisopropyl titanate, then stirring, adding hydrochloric acid, tartaric acid complex copper nitrate and polyvinyl alcohol, increasing the temperature and stirring, filtering, washing, drying and knitting to obtain the bamboo mat not prone to deformation.

Description

technical field [0001] The invention relates to the technical field of bamboo mats, in particular to a method for preparing a non-deformable bamboo mat. Background technique [0002] The traditional bamboo mat is to process bamboo into bamboo slices, remove the green layer and dead yellow layer, split the bamboo slices into bamboo strands or grind them into large vertically and horizontally connected bamboo strands, and put the bamboo strands or bamboo strands in a carbonization tank It is made by pyrolysis and carbonization, and then cured after high pressure. However, since the hardest bamboo green on the bamboo material is removed during the preparation of the bamboo mat, and the surface layer of the shaped material is opposite to the original surface layer of the original bamboo, the surface layer of the bamboo mat is relatively hard, and it is solidified into a bamboo mat after high pressure. The profile, the internal stress of the plate is large, and the profile will ...
