Problems solved by technology

[0002] China is the country with the most abundant bamboo resources in the world, and also the most developed area of ​​bamboo industry, which almost covers the related production and research of bamboo industry. Among them, moso bamboo has the largest distribution area and the most widely used, but bamboo itself contains a large number of fungi that depend on it. Nutrients for survival, the bamboo composite materials made are vulnerable to fungi such as color bacteria and molds in a humid environment, which not only affects the appearance quality of bamboo, but also causes harm to human h

Embodiment 1

[0016] A processing method for improving moso bamboo wood mildew resistance, comprising the following steps:

[0017] (1) Immerse the bamboo in magnetized water, evacuate the impregnation tank to a pressure of -0.045MPa, hold the pressure for 80 minutes, complete the pressure relief, and dry it at a temperature of 68°C until the water content is 16% for later use;

[0018] (2) After mixing mica, polyacrylamide, polyacrylate latex, and oxyindene resin in a weight ratio of 40:10:22:3, add it to water equivalent to 28 times its total weight at a temperature of 68°C, and use The mechanical vibrating screen is uniformly dispersed and stirred at a speed of 70 rpm for 28 minutes to obtain a mixed glue, and the pH value is adjusted to 4.6 to obtain an impregnating solution for use;

[0019] (3) Put the treated bamboo in step (1) into the impregnation solution, pressurize the impregnation tank to 4.5 MPa, keep the pressure for 2 hours, and take out the bamboo after pressure release;

Abstract

The invention belongs to the technical field of moso bamboo material processing, and in particular relates to a processing method for improving moso bamboo material anti-mildew, comprising magnetized water treatment, soaking liquid treatment, vacuum treatment and drying processes. Compared with the prior art, the present invention has the following advantages: in the present invention, the direction of the vascular bundles is changed by treating the bamboo with magnetized water, and the gaps on the surface of the material are increased, and then the mica and other raw materials in the soaking liquid are used to act on the bamboo. Inside the cell wall, after curing, the bamboo cells will be inflated, weakening the force between the crystallized area and the amorphous area in the bamboo, so that the size maintains the stability of the structure, and the toughness of the cured impregnation solution is greater than the residual stress inside the recombined bamboo. It can inhibit the cracking of the bamboo surface. The treated bamboo has the ability to prevent mildew due to the lignification degree of the cell wall and the crystallinity of the cellulose. Compared with the traditional process, the treatment effect is better, the stability is high, and it is easy to popularize and use. .
