Nano titanium dioxide modified wood production method

Abstract

The invention discloses a nano titanium dioxide modified wood production method, including five steps of wood pretreatment, wood modification agent preparation, wood modification liquid preparation, dipping treatment and post-drying treatment; and a wood modification agent comprises nano titanium dioxide, silica sol, fatty alcohol polyoxyethylene ether, distilled water, sodium octoborate, carbendazim, tetra hydroxmethyl sulfate, dodecyl dimethyl benzyl ammonium chloride, diammonium phosphate, boric acid and ammonium molybdate. The beneficial effects are that the nano titanium dioxide modified wood production method has the advantages of simple treatment process, easy operation, environmental friendliness, low cost, and the like, by use of the nano titanium dioxide for modification, the nano titanium dioxide modified wood has broad spectrum, high efficient and durable antibacterial effect, and the corrosion resistance, flame resistance, surface hardness, wear resistance, bending resistance, bend elastic modulus, processing good properties, dimension stability, water resistance, discoloration resistance and the like of the processed wood are greatly improved.

Description

technical field [0001] The invention relates to the technical field of wood production, in particular to a production method of nano titanium dioxide modified wood. Background technique [0002] As a natural and renewable resource, wood has the advantages of beautiful texture, natural color, comfortable texture, good plasticity, and easy processing, so it is used as an ideal material for building decoration and furniture manufacturing. However, wood is flammable and greatly affected by the environment. It is prone to discoloration, cracking, abrasion and bruising due to long-term contact with oxygen, light and moisture. It 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 structural changes in the wood ...

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.
