Problems solved by technology

However, cuproammonia preservatives are colored, and the volatilization of their solvents has adverse effects on the environment, which limits the scope of use of this type of preservatives
Commonly used anti-shock is mainly based on organophosphorus compounds, which will have a certain negative impact on the health of humans and animals when used in large doses in human settlements

Abstract

The present invention belongs to the field of preservatives, and particularly relates to a wood preservative, which comprises, by weight, 2-15% of a quaternary ammonium salt compound of boron, 2-6% of triazole, 3-10% of acetic acid, 5-15% of lignin, 2-6% of a silicon resin, and the balance of deionized water, wherein the quaternary ammonium salt compound of the boron is at least one selected from a dimethyldidecyl boron tetrafluoride quaternary ammonium salt (DBF), a boron tetrafluoride quaternary ammonium salt, an alkoxy methyl decyl dimethyl boron tetrafluoride quaternary ammonium salt and a nitrate. According to the present invention, the wood preservative has characteristics of long-term efficiency, uniform action, no trace on the wood surface, no toxicity on human and animals, no environmental pollution or destruction, and no influence on mechanical strength, good texture and good color.

Description

technical field [0001] The invention belongs to the field of preservatives, in particular to a wood preservative. Background technique [0002] Wood is a natural biological material, used in various occasions such as structural materials, civil engineering materials, etc., and is an important raw material to promote economic development. Wood has obvious biological characteristics, so it is very vulnerable to bacteria, insects and microorganisms, causing discoloration, decay and moth-eaten, which seriously affects the performance of wood, not only wastes resources, but also limits the application of wood, resulting in huge economic losses. [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, ammonia-soluble alkylamine copper and copper files. Since arsenic and chromium in copper chromium a...
