Embodiment 1

[0019] A kind of bamboo modified processing method that the present invention proposes, comprises the following steps:

[0020] S1. Cut the bamboo into sections and bake to obtain material A;

[0021] S2, soaking the material A in salt and cleaning it to obtain the pretreated bamboo;

[0022] S3. Put the pretreated bamboo into the modified solution for dipping treatment, and then perform heat treatment.

[0023] Among them, the modified solution is prepared according to the following process: mix chitosan with oxalic acid-citric acid solution, then add silver nitrate solution and zinc chloride solution for stirring, then add sodium octaborate tetrahydrate, didecyldimethyl Ammonium chloride and sodium silicate were stirred, concentrated and dried, and washed to obtain modified chitosan; the modified chitosan was mixed with paraffin emulsion, amino silicone oil, tannic acid, pyrethrum extract, neem leaf extract and detoxified chitosan. Ionized water is mixed to obtain a modifi...

Abstract

The invention discloses a bamboo modification treatment method. The method comprises the following steps that S1, bamboo is cut into sections and then is baked to obtain a material A; S2, brining andcleaning are carried out on the material A to obtain pretreated bamboo; and S3, the pretreated bamboo is placed in a modification liquid for dipping treatment, and then heat treatment is carried out.According to the bamboo modification treatment method, the bamboo is modified, so that the anti-decay performance and insect-damage-resistant performance of the bamboo are effectively improved, and abamboo product is long in service life and good in quality.

Description

technical field [0001] The invention relates to the technical field of bamboo, in particular to a method for modifying bamboo. 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, there are natural defects in bamboo, such as being easily attacked by bacteria and insects, causing decay and damage to bamboo, and affecting the appearance and service life of bamboo products. Therefore, it is an urgent problem to be solved at present to modify the bamboo to improve the anti-corrosion performance of the bamboo. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a bamboo modification treatment method. By modifying the bamboo mate...
