Abstract

The invention discloses a kind of the preservation of timber against decay processing method, after herbal medicine immersion liquid disinfection and deinsectization, timber is handled using using full-cell process；The preservative solute used in processing procedure is ACC or CDDC, and solvent is above-mentioned herbal medicine immersion liquid；Finally wood surface after the drying applies last layer whether-resisting wood oil, that is, completes preservative treatment.Chinese prickly ash, wrinkled giant hyssop and ginkgo leaf are common Chinese medicine, the effect with disinfection and deinsectization；Then preservative treatment is carried out with full-cell process, makes between gap of the preservative full of timber, play antisepsis, finally can completely cut off air to a certain extent in wood surface brush last layer whether-resisting wood oil again, prevent wood surface from aoxidizing.It can farthest delay the corruption speed of timber after handling timber using this method.

Description

A kind of the preservation of timber against decay processing method

Technical field

The present invention relates to building material field, the seemingly processing method of particularly a kind of timber.

Background technology

Timber is the plant for being capable of secondary growth, such as tree and shrubs, the lignified tissue formed, and these plants are first After raw growth terminates, the vascular cambium in rhizome comes into play, and outwards develops bast, inwardly develops timber.Timber is Common building and finishing material, are traditional construction materials, extensive use are obtained in ancient building and modern architecture, in knot On structure, timber is mainly used in framework and roof, such as beam, post, rafter, roof boarding, sets of brackets on top of the columns, and timber is always widely used in building Interior decoration and decoration, it gives the enjoyment of natural beauty, moreover it is possible to the interior space is produced warm and cordial feeling, such as bar timber floor It is indoor using most common wood floor, it is made up of the part such as keel, floor.But influenceed, held by timber self character Easily occurred the change such as discoloration, rotten by the effect of environment (sunlight, oxygen, moisture temperature etc.) and microorganism (fungi), cause wood Material softens, and every intensity step-down easily caves in, so the preservation of timber against decay processing is the key that timber is used as building materials.By anti- The timber of corruption processing possesses corrosion resistant advantage, therefore is particularly suitable for use in various outdoor architectures, and such as gardens wayside pavilion landscape, waterside pavilion are returned Corridor, flower stand fences, wooden footway etc..

The content of the invention

In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of the preservation of timber against decay processing method, effectively Prevent foxiness, the service life of prolonging wood.

In order to achieve the above object, the technical scheme that the present invention is provided is as follows：

A kind of the preservation of timber against decay processing method, comprises the following steps：

1) Chinese prickly ash, wrinkled giant hyssop, ginkgo leaf are put into water by weight 1: 2: 1, after immersion 30-40min, with small fire infusion 5- 8h, obtains deinsectization sterilization soak, soak is poured into fermentation vat, timber is fully immersed in soak, soak is treated When being cooled to room temperature, sodium fluoride and Tea Saponin are added in soak, 15-60h is soaked；

2) by step 1) in soak after timber be placed in that to dry place air-dried；

3) using full-cell process process step 2) in the timber that air-dries；Used in processing procedure and arrive preservative, the anti-corrosion Agent is by step 1) described in soak and ACC or CDDC mixing constitute；

4) by step 3) in treat after timber be put into dryer, dried at a temperature of 90-200 DEG C, until timber contains Water is no more than 8%；Normal temperature is cooled to after drying, one layer of whether-resisting wood oil is uniformly coated with wood surface.

Further, step 3) full-cell process concretely comprise the following steps：Timber is put into after process tank and vacuumized, vacuum It is not less than 80kPa, keeps adding preservative after vacuum 20-60min under vacuum, preservative, which is filled up after process tank, releases true Sky, and start pressurization, holding pressure is 1-1.5MPa, until the anti-corrosion dosage in process tank is no longer reduced.

Further, the preservative is prepared as the soak described in ACC/CDDC and step one by weight 1: 1-1.5.

Further, step 1) in sodium chloride and Tea Saponin addition be 10-50g/L soaks.

Beneficial effects of the present invention：Chinese prickly ash, wrinkled giant hyssop and ginkgo leaf are common Chinese medicine, the effect with sterilization, Sterilized before wood preservation processing, can kill wood internal microorganism that may be present and worm's ovum etc. can accelerate timber Rotten factor；Then preservative treatment is carried out with full-cell process, makes between gap of the preservative full of timber, play anti-corrosion work With finally can completely cutting off air to a certain extent in wood surface brush last layer whether-resisting wood oil again, prevent wood surface oxygen Change.It can farthest delay the corruption speed of timber after handling timber using this method.
