Wood preservation flame retardant reinforcement modification production method

Abstract

The invention discloses a wood preservation flame retardant reinforcement modification 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 tetraethoxysilane (TEOS), polyethylene glycol (PEG), phosphoric acid, water, sodium octaborate, carbendazim, zinc borate, ammonium molybdate and sodium dodecyl benzene sulfonate. The beneficial effects are that th wood preservation flame retardant reinforcement modification production method has the advantages of simple treatment process, high efficiency, low cost, strong permeability, and the like, the tetraethoxysilane is used as a precursor for formation of titanium dioxide, the titanium dioxide has reinforcement, and toughening, synergistic flame retardant and other effects, and corrosion resistance, flame resistance, surface hardness, wear resistance, bending resistance, bend elastic modulus, processing good properties, dimension stability, 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 for wood preservation and flame retardant enhancement and modification. 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, due to long-term contact with oxygen, light and moisture, wood is prone to shrinkage and swelling, poor dimensional stability, and is prone to discoloration, cracking, abrasion and contusion, and is also prone to burning and being easily eroded by insects and fungi. Therefore, the modification of wood has been widely concerned for a long time. The traditional modification methods of wood mainly include heat treatment and chemical treatment. The heat treatment method is safe and non-toxic, but it will d...

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.
