Description
Technical field
The present invention relates to a kind of preservative, is specifically a kind of garden landscape anticorrosive wood prepared using birchwood, belongs to agriculture
Industry technical field.
Background technology
Anticorrosive wood, be will common wood after manually addition chemical preservative, make it have anticorrosion, moisture-proof, anti-
The characteristics such as fungi, ant prevention, anti-mildew and waterproof.Soil and wet environment can be directly contacted, commonly using outdoors
Plate, engineering, landscape, anticorrosive wood flower stand etc., have a rest and appreciate wild beauty for people, are outdoor flooring, garden landscape, wooden autumn
Thousandth, the ideal material of recreational facilities, wooden footway etc..
Currently used timber preservative is divided into three categories：Oil-type preservation, mainly antiseptic oil, coal tar, carbolineum etc.；
Oil carries preservative, mainly including pentachlorophenol, copper naphthenate, copper 8-quinolinolate etc.；Water ballast preservative includes the water containing arsenic or chromium
Load type preservative, such as CCA (copper chromium arsenic), ACC (acid copper chromate), ACA (ammonical copper arsenite), ACZA (the molten arsenic acid zinc-copper of ammonia)
Deng such as ACQ of the waterborne preservative without arsenic or chromium (ammoniacal copper quaternary), CBA-A (copper borazol), CA-B (copper azoles) etc..These are passed
System timber preservative achieves preferable anti-corrosion effect, but pollution can be produced to environment, and is made by bioconcentration and food chain
With so that medicament is accumulated, remained in vivo, or even causes the chronic murder by poisoning such as carcinogenic, teratogenesis, gene mutation.
Plumisclerin A,a Diterpene with a New Skeleton from the Soft
CoralPlumigorgiaterminosclera Org.Lett.,2010,12(5),912–914。
It is found by the applicant that PlumisclerinA coordinates for preparing birch anticorrosive wood tool with Dauricine under certain proportion
There is the effect of anti-corrosion synergy.
The content of the invention
In view of the above-mentioned problems of the prior art, it is an object of the invention to provide a kind of garden prepared using birchwood
Woods landscape anticorrosive wood, it is to prepare anticorrosive wood favorable anti-corrosion effect by the use of birch as material, and cost is low.
To achieve these goals, the technical solution adopted by the present invention is:A kind of garden landscape prepared using birchwood
Anticorrosive wood, the anticorrosive wood pass through following steps, and birch material drying process, makes its moisture content≤13%；(3), timber pickling
Preservative processing：Dried timber is fitted into high-pressure impregnation tank, after covering lid, by high-pressure impregnation tank suction extremely
0.07MPa~0.08MPa, is kept for 30~60 minutes, preservative is then filled in high-pressure impregnation tank, removal vacuum, slowly adds
1.5~1.7MPa is depressed into, and when pressurize 2~4 is small, release, discharges preservative, be then evacuated to high-pressure impregnation tank again
0.07MPa~0.08MPa, is kept for 35 minutes, releases vacuum, takes out timber；(4), by the drying of wood after impregnation to containing
Water rate≤12%, obtains required birch anticorrosive wood.
The principle active component of the preservative is:PlumisclerinA and Dauricine, PlumisclerinA its
Structural formula is as follows：
The ratio between the PlumisclerinA and the parts by weight of Dauricine are 1:1-30:1, PlumisclerinA with
The weight of Dauricine accounts for the 0.3%~5% of preservative gross weight.
The present invention prepares anticorrosive wood, low manufacture cost by regarding birch as raw material, and preservative utilizes native compound
PlumisclerinA and Dauricine compound preservative, it is pollution-free, it is found by the applicant that PlumisclerinA matches somebody with somebody with Dauricine
The 5 birch anticorrosive woods for finding to prepare under specific ratio have good anti-mold effect, particularly in PlumisclerinA
It is 13-16 with the ratio between parts by weight of Dauricine:Between 1, it cooperates with anti-mold effect apparent, and small toxicity, is good for
Kang Huanbao.
Embodiment
Dauricine, No. CAS:524-17-4, Chengdu Zhi Biaohuachun Bioisystech Co., Ltd etc. is on sale.
The preparation method of compound PlumisclerinA involved in the present invention is referring to document：(Plumisclerin A,a
Diterpene with a New Skeleton from the Soft CoralPlumigorgiaterminosclera
Org.Lett.,2010,12(5),912–914)。
Effect test:
Material birch anticorrosive wood is tried, birch material drying process, makes its moisture content≤13%；(3), at timber pickling preservative
Reason：Dried timber is fitted into high-pressure impregnation tank, after covering lid, by high-pressure impregnation tank suction to 0.07MPa~
0.08MPa, is kept for 30~60 minutes, then fills preservative in high-pressure impregnation tank, removal vacuum, slowly it is forced into 1.5~
1.7MPa, and when pressurize 2~4 is small, release, discharges preservative, then by high-pressure impregnation tank be evacuated to again 0.07MPa~
0.08MPa, is kept for 35 minutes, releases vacuum, takes out timber；(4), by the drying of wood after impregnation to moisture content≤
12%, obtain required birch anticorrosive wood.
Birch is all processed into the sample of 100mm × 60mm × 10mm (length × width x thickness) in this experiment.
Mould:Aspergillus niger (AspergillusnigerV.Tiegh), Penicillium citrinum (Penicilliumcitrintim
Thom), strain is provided by INST OF WOOD INDUDTRY CHINESE.
Experimental facilities
MJX-8503 Intelligent culture casees, BCL-1360-B type superclean benches etc..
Same group of sample is placed on groined type in beaker to put, weight bears down on one to prevent from floating, and is subsequently poured into liquid simultaneously
Its liquid level is set to be higher by sample material top 2cm.After taking-up, the raffinate of specimen surface is wiped.Blank control group sample is soaked with sterile water,
Sample after processing is placed in ventilation, and gas is done 21 days.
Anti-mold effect is evaluated
With reference to national standard《Mould inhibitor prevents the experimental method of timber mould and Stain fungi》, the interior of detection process sample
Fungicidal properties.Sample is connect in 4 weeks after bacterium, and the killed value and specimen surface for observing and recording sample for every 3 days are gone mouldy
Degree, and the killed value of reference sample.
| The degree that specimen surface goes mouldy | Examination bacterium infection area is killed value |
| Specimen surface is without mycelia | 0 |
| Specimen surface infection area ＜ 1/4 | 1 |
| Specimen surface infects area 1/4~1/2 | 2 |
| Specimen surface infects area 1/2~3/4 | 3 |
| Specimen surface infection area ＞ 3/4 | 4 |
Medicament is to the preventing efficiency calculation formula of mould:
In E=(1-Dt/D0) × 100% formula:E is preventing efficiency (%)；Dt is the average killed value of chemicals treatment sample；
D0 is the average killed value of untreated control sample,
After indoor mould proof experiment in 4 weeks, the prevention of anticorrosive wood sample prepared by various concentrations component preservative to mould
Effect is shown in Table.
The auxiliary formula of preservative is：Polyvinylpyrrolidone 2%, n-butanol 5%, excess water,
A is PlumisclerinA, and B is Dauricine.
By experimental result it can be seen that single PlumisclerinA and Dauricine prepares anticorrosive wood tool as preservative
There is certain anti-mold effect, but effect is not notable, substantial amounts of experiment shows only PlumisclerinA and Dauricine 13-
16:Anticorrosive wood prepared by 1 ratio preservative is good for the prevention effect of mould, and other ratio groups are not notable, it is seen that
PlumisclerinA is with Dauricine in 13-16:Cooperate with anti-corrosion effect obvious as birch anticorrosive wood prepared by preservative when 1,
With significant progress.
