Problems solved by technology

In terms of anti-mildew brakes: CCA (copper chromium arsenic mixture), sodium pentachlorophenate, ACQ and other compounds are mainly used in the market recently. These compounds contain arsenic or sodium pentachlorophenate that are carcinogenic to humans, so they are used When wood is treated, it also poses a potential risk to the health of humans and animals that come into contact with it

Abstract

The invention relates to wood protection technology, in particular to a wood insect-proof and mildew-proof agent and a preparation method thereof. A kind of insect-proof and anti-fungal agent for wood, comprising insect-repellent, anti-mold agent, solvent, co-solvent, permeation aid and stabilizer, wherein the weight percentage content of each component is respectively: insect repellent 0.1-70%, anti-mold agent 0.1% ~50%, solvent 1~40%, cosolvent 1~30%, penetration aid 1~20%, stabilizer 1~40%. The invention has the characteristics of high efficiency, broad spectrum, environmental protection, good water solubility and fixability, and the insect-proof and mildew-proof agent is made into a solution, so that the protection treatment is simple and easy. In addition, the present invention also provides a preparation method of the above wood insect-proof and mildew-proof agent.

Description

technical field [0001] The invention relates to wood protection technology, in particular to a wood insect-proof and mildew-proof agent and a preparation method thereof. Background technique [0002] In the existing market, there are independent insect repellents and mildew-proof agents related to wood insect-proof and mildew-proof products. In terms of insect repellents: the insect repellents used in the market recently mainly use organophosphorus compounds, such as chlorpyrifos, and pyrethroid compounds such as fenvalerate, permethrin, cypermethrin, bifenthrin, etc. as active ingredients, these compounds It acts on the nervous system of insects, causing excitement, paralysis and death of poisoned insects. However, if it is used in large doses in the living environment, it will cause certain negative effects on the health of humans and animals. Especially chlorpyrifos, long-term contact with infants and young children has the potential risk of irreversible damage to the r...
