Problems solved by technology

However, the current organic treatment agents mostly use organic emulsions, resins and other components, which introduce difficult-to-degrade components into wood, reduce the environmental performance of wood, and have poor compatibility with inorganic modification systems, forming organic-inorganic treatment systems. The stability is not high, prone to flocculation and denaturation, and the processing conditions are relatively harsh

Embodiment Construction

[0020] An organic-inorganic impregnation treatment method for wood, comprising the following steps:

[0021] (1) Firstly impregnate the dried wood with sodium silicate solution under normal pressure for 3 hours, then soak it with acetic acid solution under normal pressure for 1 hour after taking it out, rinse the surface of the wood with water and dry it;

[0022] (2) Mix the enzymatic lignin, polyethylene glycol equivalent to 2 times the weight of the enzymatic lignin, and glycerol equivalent to 0.5 times the weight of the enzymatic lignin, first finely grind it with a grinder for 15 times, and then Add concentrated sulfuric acid equivalent to 1% of the weight of enzymatic lignin and react at 120°C for 0.5h. After cooling, add water equivalent to 20 times the weight of enzymatic lignin and adjust the pH to 6 to obtain a liquefied enzymatic cellulose treatment solution;

[0023] (3) Treat the wood treated in step (1) under negative pressure conditions for 0.5h, and then soak i...

Abstract

The invention discloses an organic-inorganic immersion treatment method of wood. The organic-inorganic immersion treatment method comprises the steps that the wood is immersed in a sodium silicate solution at a normal pressure first and then is immersed in an acetic acid solution at a normal pressure; zymolytic lignin is treated through physical grinding and then is subjected to acidolysis and liquefaction in a polyhydroxy-alcohol solvent to obtain liquefied zymolytic lignin; and the treated wood is immersed in liquefied zymolytic lignin conditioning fluid in vacuum in a pressurization mode and then is immersed in the liquefied zymolytic lignin conditioning fluid at a normal pressure; and finally, the wood is dried. By adoption of the organic-inorganic immersion treatment method of the wood, the strength, corrosion resistance, flame resistance, durability and stability of the wood can be improved, and thus, the comprehensive performance of the wood is effectively improved; and the organic-inorganic immersion treatment method is easy to implement and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of wood treatment, in particular to an organic-inorganic impregnation treatment method for wood. Background technique [0002] As a natural material with low environmental pollution, natural degradation and recycling, wood is widely used in daily life, and its consumption is huge, especially high-quality wood is facing the plight of resource shortage. Although fast-growing wood can be produced quickly, its material is soft, its physical and mechanical properties are poor, and it is easy to shrink and deform, which limits its application range. Therefore, the use of chemical, physical or mechanical methods to process wood is conducive to improving the properties of wood, realizing the high performance of wood and the effective utilization of inferior wood, which has become an effective way to change the current situation of wood application. [0003] At present, the main method of wood processing is to overc...
