Problems solved by technology

However, the most widely used preservatives contain elements harmful to the human body, such as arsenic, chromium, etc., both of which are highly toxic substances, and excessive copper content can also cause harm to the human body
However, some existing green wood preservatives and insect repellents also have problems such as large dosage, unsatisfactory effect, and reduced wood strength.

Abstract

The invention discloses a wood anti-corrosion and anti-insect agent. The wood anti-corrosion and anti-insect agent is prepared from, by weight, 10-20 parts of rohdea japonica, 20-30 parts of common jasmin orange, 5-10 parts of mint, 10-15 parts of green tea, 20-30 parts of tagetes erecta, 15-20 parts of peach leaves, 30-50 parts of neem, 20-30 parts of litsea cubeba, 1-2 parts of nano silicon dioxide and 0.5-1 part of a carbon nano tube. The invention further discloses a preparation method of the wood anti-corrosion and anti-insect agent. Materials used for the wood anti-corrosion and anti-insect agent are environmentally friendly, free of pollution or poison and good in anti-mould and anti-insect effect.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a wood antiseptic and insect repellant. Background technique [0002] Solid wood furniture and buildings are deeply loved by people for their natural texture and changeable shapes. However, solid wood furniture and buildings are prone to mold and worms. This is because the wood contains protein, starch, oil, cellulose, etc., which are very suitable for mold production and reproduction, and termites and other insects are easy to parasitize. Especially in spring when the temperature rises and the air humidity is high, the mold reproduces faster, and insects are more likely to reproduce and grow in a hot and humid environment. Therefore, before solid wood is made into furniture or building materials, it must be treated with anti-corrosion and insect-proof. Inorganic wood preservatives are preservatives with excellent anti-corrosion properties, and the wood trea...
