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...
