Abstract

The invention discloses a wood pest control agent and a method using the wood pest control agent for treating wood. The wood pest control agent comprises the following components by mass: 15%-20% of carbendazim, 3%-10% of imidacloprid, 1%-3% of bronopol, 2%-8% of 4, 5-dichloro-N-octyl-4-isothiazolin-3-one, 3%-10% of 8-hydroxyquinoline, 8%-12% of dithiocyano-methane, 10%-15% of dodecyl dimethyl benzyl ammonium chloride, 1%-4% of fatty alcohol polyoxyethylene ether and 20%-50% of water. The beneficial effect is that the wood pest control agent has the advantages of high efficiency and broad-spectrum pest control and sterilization effects, the processed wood maintains the original features, meanwhile has excellent anti-corrosion, mouldproof, insect-resistant, antibacterial properties, and is simple in process, practical, environmentally-friendly, easy to control, low in cost, and easy to popularize and apply.

Description

A kind of wood preservation from decay agent and utilize its process timber method

Technical field

The present invention relates to wood producing technical field, specifically a kind of wood preservation from decay agent and utilize its process timber method.

Background technology

Timber as a kind of resource of natural reproducible, and has beautiful texture, color and luster is natural, texture is comfortable, plasticity is good, be easy to the advantages such as processing, thus by the ideal material as construction and decoration and Furniture manufacture.But timber is owing to contacting with oxygen, light, moisture for a long time, easily by the erosion of entomogenous fungi moth, this will significantly limit effect and the application of timber.Therefore, timber before use, often selects appropriate insect-proof agent to carry out protective treatment, good delays the effects such as foxiness, mouldization by playing.But, traditional wood preservation from decay agent great majority, containing the harmful components such as heavy metal, formaldehyde, use and will cause great potential hazard, and the performance of some insect-proof agent are single to environment and the mankind, the scope of antagonism domestomycetes, worm is narrow, is often difficult to the ideal effect playing expection.Therefore, develop a kind of efficient, environmental protection, the insect-proof agent of wide spectrum will seem very necessary and significant.The timber that nowadays China use after insect protected and insect-prevention treatment is little, and mostly uses the mankind and the large traditional wood preservation from decay agent of environmental hazard.

Summary of the invention

The object of the present invention is to provide the wood preservation from decay agent of a kind of efficient, environmental protection, wide spectrum.Another object of the present invention additionally provides the method utilizing this insect-proof agent process timber.

The technical solution adopted for the present invention to solve the technical problems is: a kind of wood preservation from decay agent, its component by mass percent proportioning is: carbendazim 15% ~ 20%, Imidacloprid 3% ~ 10%, the chloro-N-octyl group-4-isothiazoline of bromine nitre propyl alcohol 1% ~ 3%, 4,5-bis--3-ketone 2% ~ 8%, oxine ketone 3% ~ 10%, dithiocyano-methane 8% ~ 12%, dodecyl benzyl dimethyl ammonium chloride 10% ~ 15%, AEO 1% ~ 4%, water 20% ~ 50%.

The present invention utilizes the method for above-mentioned wood preservation from decay agent process timber, comprises the following steps:

(1), timber pretreatment: the timber selected is carried out drying, makes the moisture content of timber be reduced to 8% ~ 25%;

(2), insect-proof agent is prepared: take carbendazim 15% ~ 20%, Imidacloprid 3% ~ 10%, bromine nitre propyl alcohol 1% ~ 3%, 4 by weight ratio, the chloro-N-octyl group of 5-bis--4-isothiazoline-3-ketone 2% ~ 8%, oxine ketone 3% ~ 10%, dithiocyano-methane 8% ~ 12%, dodecyl benzyl dimethyl ammonium chloride 10% ~ 15%, AEO 1% ~ 4%, water 20% ~ 30%, then mix, obtain described insect-proof agent;

(3), insect protected solution is prepared: it is 10% ~ 25% solution that the insect-proof agent that step (2) is obtained is diluted with water to mass percent concentration;

(4), impregnation process: the timber that step (1) obtains is put into airtight impregnation process tank, vacuumize and to make in tank vacuum at-0.08 ~-0.1MPa, keep 30 ~ 60min, insect protected solution step (3) prepared again injects impregnation process tank, and make to flood timber completely, then remove vacuum, be forced into 0.6 ~ 0.9MPa, keep 30 ~ 90min;

(5), rear drying process: pressure relief, discharge remaining insect protected solution, take out timber air-dry residual without obvious water mark to surface, move to dry kiln again and carry out drying, baking temperature 70 DEG C ~ 95 DEG C, drying time, 3 ~ 7d, was then cooled to room temperature, namely obtained the process timber that moisture content is 5% ~ 15%.

The invention has the beneficial effects as follows, insect-proof agent of the present invention has efficiently, the insect protected of wide spectrum, bactericidal effect, timber is after treatment keeping will having excellent anticorrosion, mildew-resistant, insect protected, anti-microbial property while primary characteristic, and treatment process is simple, practical, environmental protection and be easy to control, cost is low, easy to utilize.
