Abstract

The invention relates to a bamboo wood reinforcing and synergistic treatment method. A nano cellulose dispersion liquid is prepared by adopting a sulfuric acid hydrolysis method, nano-zinc oxide is generated on the surface of nano-cellulose in situ by taking the nano cellulose dispersion solution with a certain concentration as a precursor solution, and a cellulose dispersion liquid is compoundedand improved and is impregnated into pores of bamboo wood in a specific mode to fill, bond and reinforce wood tissues, so that the hardness, strength and size stability of the treated material are enhanced, and the mildew-proof and corrosion-proof performance is obviously improved. The method is suitable for reinforcing and synergistic treatment of loose wood such as fast-growing wood and man-madeforests, and is also suitable for reinforcing and repairing of mildly rotten wood.

Description

[0001] (1) Technical field

[0002] The invention relates to a method for enhancing and synergizing treatment of bamboo wood.

[0003] (2) Background technology

[0004] my country's natural forest resources are scarce, while the area of ​​planted forests occupies the largest area in the world. The artificial fast-growing wood has reached the mature stage and can be felled and used. However, the material of the fast-growing wood is relatively loose, the strength and hardness are not enough, and the anti-mildew and anti-corrosion performance is poor. If the fast-growing wood can be properly improved, it can effectively replace imported hard broad-leaved wood and reduce my country's dependence on imported wood.

[0005] Nanocellulose (CNC) is a nano-scale fiber material extracted from natural fibers. It has high crystallinity, high strength, large surface area, high reactivity and strong adsorption capacity. The source of nanocellulose raw materials is abundant. The extraction p...
