Nano silicon dioxide modified wood production method

Abstract

The invention discloses a nano silicon dioxide modified wood production method including five steps of pretreatment, preparation of a wood modification agent, preparation of a wood modification fluid, dipping treatment and post-drying treatment, wherein the wood modification agent comprises nano silicon dioxide, fatty alcohol polyoxyethylene ether, distilled water, trimethyl borate, dodecyl dimethyl benzyl ammonium chloride, N-(2-benzimidazole)-methyl carbamate, and imidacloprid. The beneficial effect is that the nano silicon dioxide modified wood production method has the advantages of simple treatment process, easy operation, low cost, good treatment effect, no toxicity, environmental friendliness and the like, the treated wood has no obvious appearance change, and wood dimensional stability, density, surface hardness, bending strength and bending elastic modulus, good processing properties, wear resistance, anti-corrosion flame retardant properties are greatly increased.

Description

technical field [0001] The invention relates to the technical field of wood production, in particular to a production method of nano silicon dioxide modified wood. Background technique [0002] As a natural renewable resource, wood is ideal due to its light weight, small volumetric weight, high strength, high strength-to-weight ratio, low acoustic and thermal conductivity, good electrical insulation of dry wood, good material color, and beautiful texture. Indoor and outdoor construction and decoration materials. However, due to long-term contact with oxygen, light and moisture, wood is prone to discoloration, cracking, abrasion and bruising, and is also vulnerable to microorganisms and insects. Therefore, the modification of wood has been widely concerned for a long time. Traditional wood modification methods mainly include heat treatment and chemical treatment. The heat treatment method is safe and non-toxic, but it will cause different degrees of degradation and structu...

AI Technical Summary

Problems solved by technology

The way of heat treatment is safe and non-toxic, but it will cause different degrees of degradation and structural changes in the wood components, reduce the mechanical strength of the wood, and at the same time deepen the color of the wood, affecting the aesthetics of the wood

Chemical treatment adopts the method of treating chemicals, which has low cost and simple process, but the heavy metal ions such as copper, chromium, arsenic, and compounds such as chlorine and phenolic aldehyde contained in most chemicals have potential harm to the environment and humans and animals.
