Abstract

The invention discloses a modification processing method for bamboo wood. The modification processing method for the bamboo wood comprises the following steps of (1) cutting the bamboo wood into sections, baking the sections and obtaining a material A; (2) acid leaching the material A, cleaning the material A and obtaining the pretreatment bamboo wood; and (3) placing the pretreatment bamboo woodinto a modification solution for impregnation treatment and then conducting heat treatment. According to the modification processing method for the bamboo wood, by modifying the bamboo wood, the mildew proof and moth proof performances of the bamboo wood is effectively improved, the quality of the bamboo wood is improved and the service life of bamboo products is prolonged at the same time.

Description

technical field [0001] The invention relates to the technical field of bamboo processing, in particular to a bamboo modification processing method. Background technique [0002] As a natural polymer material with excellent performance, bamboo is widely used in human society. With the continuous development of science and technology, many new materials emerge in an endless stream, and bamboo still plays an important role in people's life with its natural advantages. However, bamboo has natural defects, such as being easily attacked by bacteria and insects, mildew and insects, which affect the appearance and service life of bamboo products. Therefore, it is an urgent problem to be solved at present to carry out modified processing to bamboo to improve the anti-mildew and insect-proof of bamboo. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a bamboo modification processing method, which can ef...
