Nontoxic environmentally friendly wood flame retardant preservative and preparation method thereof

Abstract

The invention discloses a nontoxic environmentally friendly wood flame retardant preservative and a preparation method thereof. The nontoxic environmentally friendly wood flame retardant preservative comprises the following components by mass: 2-6% of polyethylene glycol, 8-12% of trimethyl borate, 2-4% of tetra (hydroxmethyl) sulfate, 3-6% carbendazim, 0.1-1% of nano titanium dioxide, 6-12% of amidinourea phosphate, 4-7% of boric acid, 6-9% of water-soluble ammonium polyphosphate, 1%-3% of ammonium molybdate, 3%-8% of nano silicon dioxide, 0.1%-1% of isooctanol phosphate, 0.1%-1% of sodium polyacrylate, 0.5-1% of fatty alcohol polyoxyethylene ether and 30%-60% of water. The beneficial effects are that the nontoxic environmentally friendly wood flame retardant preservative has excellent flame retardant, smoke suppression, anticorrosive, mouldproof, insect-resistant and sterilization multi-functional synergy effects on wood processing, and is broad in adaptability, efficient, durable, stable in chemical performance, good in permeability, strong in erosion resistance, non-toxic and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a non-toxic and environment-friendly wood flame retardant preservative and a preparation method thereof. Background technique [0002] Wood is a renewable, recyclable and naturally degradable green material and biological resource. It has the advantages of beautiful texture, natural color, comfortable texture, good plasticity, and easy processing. However, wood also has some defects, such as: easy to shrink and swell, easy to mildew and decay, easy to be eaten by insects, easy to burn, etc. These defects will greatly limit the application effect and application field of wood. In order to obtain high-performance and high-value-added wood products, it is usually necessary to carry out necessary flame-retardant and anti-corrosion modification treatments before the wood is used, but most of the wood flame retardants and wood preservatives in the prior art have single p...

These defects will greatly limit the application effect and application field of wood

In order to obtain high-performance and high-value-added wood products, it is usually necessary to carry out necessary flame-retardant and anti-corrosion modification treatments before the wood is used, but most of the wood flame retardants and wood preservatives in the prior art have single performance, And some contain a large amount of toxic substances that cause great harm to humans and the environment in their components, so it is very necessary and urgent to develop a multifunctional, non-toxic and environmentally friendly wood flame retardant preservative.
