Problems solved by technology

o-Phenylphenol has obvious bladder cancer-causing effect on experimental animal oil, moderately toxic to humans, and irritating effect on skin
At the same time, some anti-mildew and insect repellents have low solubility, or in order to improve the solubility, they are very corrosive to conventional metals, which have many defects in practical applications.

Embodiment 1

[0032] 1. Preparation of new wood mildew and insect repellent:

[0033] The weight percent of each component is

[0034] Carbendazim 15%;

[0035] Borax 40%;

[0036] BAC 45%;

[0037] Hydrochloric acid (1+1) is 2.4 times that of carbendazim.

[0038] The preparation method is as follows:

[0039] Add carbendazim to hydrochloric acid (1+1), stir to dissolve, add borax and stir evenly, and finally add BAC, stir for 2 to 3 hours to make the solution evenly mixed, and then a clear and transparent new wood mildew and insect repellant can be prepared solution. After testing, its pH value is 3.6, and its stability is good.

[0040] 2. Anti-mildew, anti-insect, metal corrosion and animal toxicity experiments: Carry out animal toxicity test and ecotoxicity test on the above-mentioned wood anti-mold and insect-proof agent; Mildew insect repellent dilution, and based on the total weight of the mildew insect repellent dilution, the weight percentage of the active ingredient compos...

Abstract

The invention discloses a novel wood mould-proofing insect-resist agent which contains effective components and solvent; the effective components comprise carbendazim, sodium borate and dodecyl dimethyl benzyl ammonium chloride; the novel wood mould-proofing insect-resist agent is formed by compounding various sterilization insecticides, the biotoxicity is reduced and the ecological destruction is reduced; in addition, the novel wood mould-proofing insect-resist agent has the characteristics of remarkable and overall drug effect, long residual period, high penetrability and good environment-protection performance; the novel wood mould-proofing insect-resist agent is suitable for four-protection treatment of the wood and protective treatment of indoor wood products and components of houses; the treatment method of the rubber wood can completely replace the usage of BBP preservative to toxic materials.

Description

technical field [0001] The invention belongs to the field of wood anticorrosion, and in particular relates to a novel wood mildew-proof and insect-proof agent. Background technique [0002] Among the commonly used antifungal and insect repellent agents in the market, most of the antifungal agents in use are biologically toxic, such as chlorothalonil and o-phenylphenol. Chlorothalonil is a low-toxic fungicide with low toxicity to animals, but it is highly toxic to fish, and its ecotoxicity is poisoning. O-phenylphenol has obvious bladder cancer-causing effect on experimental animal oils, moderate toxicity to humans, and irritating effect on skin. At the same time, some anti-mildew and insect repellents have low solubility, or are very corrosive to conventional metals in order to increase solubility, and have many defects in practical applications. [0003] Today, when people have higher requirements for the ecological environment, the demand for environmentally friendly woo...
