Problems solved by technology

[0002] Because the bamboo and rattan chair has a dense protective layer on the surface, it can well protect the internal structure of the bamboo and rattan chair from being damaged. However, when in use, there are many restrictions on the use environment of the bamboo and rattan chair, which requires ventilation and heat dissipation. For some areas, there will be A period of humid weather, therefore, will inevitably have a humid use environment, but the bamboo and rattan chairs made by the prior art are used in a dark and humid environment, which will seriously affect the toughness of the bamboo strips, and it is easy to mold and deform. It is easy to age in the environment, therefore, it is necessary to process the material of the bamboo and rattan chair to improve its performance

Abstract

The invention belongs to the technical field of materials made of bamboo and particularly relates to a processing method for enhancing the ageing resistance of a bamboo batten. According to the specific content of boiling and pretreatment, Chinese pepper straws, paulownia wood and the bamboo battens are placed in a sodium hydroxide solution to be boiled for 6-8 hours; as to the primary drying condition, the low-power microwave condition is adopted, and then hot air drying is conducted; as to impregnation, the carbonized bamboo battens are placed in a dipping tank to be dipped; and as the secondary drying condition, the water content is lowered to be lower than 7% through hot air drying. Compared with the prior art, the processing method for enhancing the ageing resistance of the bamboo battens has the advantages that boiling, pretreatment, primary drying, impregnation and secondary drying of the bamboo battens are improved, the pore structure, the pore diameter distribution and the like of surface fiber of the bamboo battens are changed because the Chinese pepper straws are added during boiling, through cooperation of primary drying and impregnation process, the surface structure of the bamboo battens is improved, and the boiling water resistance and the ageing resistance of the bamboo battens are improved; and the retention capacity of bending strength and rigidity of the bamboo battens is good in a humid and stuffy environment.
