Description

A kind of production method of preserving timber

Technical field

The present invention relates to wood producing technical field, specifically a kind of production method of preserving timber.

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.

Summary of the invention

The object of the present invention is to provide that a kind for the treatment of process is simple, efficient, the production method of the preserving timber of environmental protection and low cost.

The technical solution adopted for the present invention to solve the technical problems is: a kind of production method of preserving 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), anticorrisive agent is prepared: in agitator, add following component by mass percent: polyethylene glycol 2% ~ 8%, bromine nitre propyl alcohol 1% ~ 3%, 4,5-bis-chloro-N-octyl group-4-isothiazoline-3-ketone 2% ~ 5%, Imidacloprid 5% ~ 10%, the chloro-3,5-dimethylphenol 8% ~ 15% of 2-, dithiocyano-methane 10% ~ 15%, dodecyl benzyl dimethyl ammonium chloride 15% ~ 20%, N-(2-benzimidazole base)-methyl carbamate 10% ~ 15%, fatty alcohol Ethoxylate 15% ~ 35%, and make to be mixed together evenly, anticorrisive agent obtained used;

(3), impregnating fluid is prepared: it is 10% ~ 30% mixed liquor that the anticorrisive 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, impregnating fluid step (3) prepared again injects impregnation process tank, and make to flood timber completely, then remove vacuum, in process tank, apply 0.6 ~ 1.5MPa air pressure, and be heated to 40 DEG C ~ 70 DEG C, keep 1 ~ 4h;

(5), rear drying process: pressure relief and after temperature is cooled to room temperature, discharge remaining modification liquid, take out timber air-dry residual without obvious water mark to surface, move to dry kiln again and carry out drying, first baking temperature is controlled at 60 DEG C ~ 85 DEG C, keep 12 ~ 24h, then 90 DEG C ~ 120 DEG C are warming up to, and after keeping 8 ~ 16h, be cooled to room temperature, namely obtain the preserving timber that moisture content is 5% ~ 15%.

The invention has the beneficial effects as follows, it is simple, efficient and be easy to the advantages such as operation that the present invention has treatment process, and timber is after treatment while keeping primary characteristic, to there is excellent anticorrosion, mildew-resistant, insect protected, the effect such as antibacterial, and the feature of environmental protection is good, stable performance, durable.
