Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with specific preferred embodiments.

[0014] A kind of production method of nano silicon dioxide modified wood, comprises the following steps:

[0015] (1) Wood pretreatment: After peeling and sawing the log into required size specifications, dry it at 50°C-80°C for 8-24 hours, and control the moisture content of the wood to 8%-25%. Then microwave treatment for 10-30 minutes; wherein, the log is suitable for any wood, including poplar, birch, nanmu, eucalyptus, fir, pine and the like.

[0016] (2) Preparation of wood modifier: Add 20-30 parts by mass of dry nano-silica into the mixer, then add 1-2 parts by mass of fatty alcohol polyoxyethylene ether and 400-500 parts by mass of distilled water, at 60 ℃~80℃, stirring at a high speed of not less than 6000r / min for 20~50min, then ultrasonically dispersed for 15~30min, and then cooled to 30℃~50℃, adding 10~15 mass parts of trim...

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...
