Description

A kind of timber preservative and utilize its process timber method

Technical field

The present invention relates to wood treatment agent technical field, specifically a kind of timber preservative 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.On the other hand, timber has obvious biological characteristics, easily goes mouldy rotten, easily by the erosion of entomogenous fungi moth, has a strong impact on result of use and the application of timber.Therefore, timber before use, is often selected appropriate anticorrisive agent to carry out necessary protective treatment, can be increased the service life preferably and improve serviceability etc.But, traditional timber preservative great majority are containing the harmful components such as heavy metal, formaldehyde, environment and the mankind are used and will cause great potential hazard, and the performance of some anticorrisive agent is single, the scope of antagonism domestomycetes, worm is narrow, is difficult to the antiseptic effect that the timber after making process reaches expection.Therefore, develop a kind of anticorrisive agent that is efficient, environmental protection and will seem very necessary and significant.

Summary of the invention

The object of the present invention is to provide a kind of efficient, environmental protection and timber preservative easy to use.Another object of the present invention additionally provides the method utilizing this anticorrisive agent process timber.

The technical solution adopted for the present invention to solve the technical problems is: a kind of timber preservative, and its component by mass percent proportioning is: polyethylene glycol 40% ~ 50%, dodecyl benzyl dimethyl ammonium chloride 10% ~ 15%, dithiocyano-methane 10% ~ 20%, copper naphthenate 5% ~ 10%, calcium propionate 5% ~ 10%, bromine nitre propyl alcohol 2% ~ 8%, Sodium Benzoate 1% ~ 4%, sodium pyrithione 1% ~ 2%, AEO 0.5% ~ 2%.

The present invention utilizes the method for above-mentioned timber preservative 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), anticorrisive agent is prepared: take polyethylene glycol 20% ~ 30%, dodecyl benzyl dimethyl ammonium chloride 10% ~ 15%, dithiocyano-methane 8% ~ 12%, copper naphthenate 5% ~ 10%, calcium propionate 5% ~ 10%, bromine nitre propyl alcohol 2% ~ 8%, Sodium Benzoate 1% ~ 4%, sodium pyrithione 1% ~ 2%, AEO 0.5% ~ 2% by weight ratio, then mix, obtain described insect-proof agent;

(3), impregnating fluid is prepared: it is 15% ~ 25% solution 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, be forced into 0.3 ~ 0.7MPa, 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 preserving timber that moisture content is 5% ~ 15%.

The invention has the beneficial effects as follows, anticorrisive agent of the present invention has efficiently, lasting, environmental protection and the advantage such as applicability is wide, timber is after treatment keeping will having excellent anticorrosion, mildew-resistant, insect protected, the effect such as antibacterial while primary characteristic, and treatment process is simple, practical and be easy to operation.
