Wood preservative

Abstract

The invention discloses a wood preservative. The preservative comprises the following components, by weight, borate 15-45%, quaternary ammonium salt 6-15%, chlorothalonil 5-10%, cosolvent 4-10% and the balance solvent, wherein the solvent is one or a plurality of dimethylbenzene, glycerol and water, and the cosolvent is polyethylene glycol, urea formaldehyde preshrinking liquid or ethylene. The wood preservative is colorless, odorless, safe and environment-protection, simultaneously has the functions of corrosion prevention, mold prevention, insect prevention and antitarnish, and can rest assured use indoor and outdoor.

Description

technical field [0001] The invention belongs to the technical field of wood modification, and mainly relates to a wood preservative. Background technique [0002] Wood preservatives are a class of chemical agents applied to wood and wood products to inhibit or prevent fungi, insects, and marine borers from growing and multiplying in wood. Antiseptic treatment of wood can prolong the service life of wood products and reduce the demand for wood, which is an important way to protect forest resources. [0003] Wood preservatives are divided into three categories: anti-corrosion, anti-mildew and anti-insect according to the control objects and functions. Commonly used anti-corrosion and anti-fungal agents include copper chromium arsenic (CCA), ammonia-soluble alkylamine (ammonia) copper (ACQ) and copper file (CA). Since arsenic and chromium in CCA are toxic substances, they are easy to cause damage to the human body. , especially when used indoors, it is more harmful to the hum...

AI Technical Summary

Problems solved by technology

my country's wood protection industry is in a new period of development. Both CCA and ACQ wood preservatives are used at the same time. Most of the preservative-treated wood and wood products are used outdoors, because cuproammonia series preservatives are colored, and their The volatilization of solvents will have adverse effects on the environment, which often restricts this kind of preservative wood from being widely used indoors

Commonly used insect repellents are mainly organophosphorus compounds, such as chlorpyrifos and pyrethroids. These compounds act on the nervous system of insects, causing excitement, paralysis and death of poisoned insects. Cause certain negative effects on human and animal health
