Abstract
The invention discloses a natural compound-containing wood preservative. The natural compound-containing wood preservative comprises Cyanogramide and scopolamine methobromide, wherein the Cyanogramide and the scopolamine methobromide are in the weight part ratio of 1:1 to 20:1. The natural compound-containing wood preservative is found to have a very good wood anti-mould effect by matching the Cyanogramide and the scopolamine methobromide in a specific ratio, and particularly, the synergic anti-mould effect of the natural compound-containing wood preservative is very obvious when the Cyanogramide and the scopolamine methobromide are in the weight part ratio of 8 to 11:1.
Description
Technical field
The present invention relates to a kind of preservative, specifically a kind of timber preservative containing native compound, belong to agriculture skill
Art field.
Background technology
Up to the present, the most commonly used method preventing foxiness is anti-corrosion with chemical agent, preservative produce and
Leakage during use and oozing out, and the discarded and burning of preservative-treated timber all can adversely affect to environment, and
The health of the harm mankind.Because environmental problem is increasingly paid close attention to by people, also become the key selecting preservative.
Currently used most be waterborne-type preservation, account for that preservative uses total amount 3/4.Because single preservative resists
Domestomycetes, worm scope narrow, typically now two or more preservative are mixed by a certain percentage, not only can overcome
Weak point when single preservative uses, but also some new characteristics can be produced.At present, compound preservative is each in the world
State has obtained widest application, and achieves good effect.Because traditional preservatives have many deficiencies, people are forced to grind
Study carefully and find to person poultry harmless, environmentally safe, only poisonous to microorganism new food preservative.Study more inclusion at present
Water miscible alkylammonium class compound (AAC), ammonia molten alkylamine copper (ACQ), boride, cupric dimethyldithio carbamate
And oil-soluble Bravo (CTL), organic iodide (IPBC) etc. (CDDC).For the essence of wood preservation, exploitation nontoxic,
Efficient and practical wood preservation method, reduces environmental pollution, and protection human ecological environment is anticipated with making full use of existing resource
Justice is far-reaching.Cyanogramide is secondary from different wall actinomycetes Actinoalloteichuscyanogriseus WH1-2216-6
A structure novelty is found in raw metabolite.There is the indole alkaloid of activity for reversing tumor cell multidrug resistance, first
It is published in Cyanogramide with a new spiro [indolinone-pyrroloimidazole] skeleton from
3708-11 page of Actinoalloteichus cyanogriseus.Organic letters 2014 14 phase of volume 16.
It is found by the applicant that Cyanogramide is coordinated under certain proportion with scopolamine methobromide having for wood preservation
The effect of potentiation.
Content of the invention
The problem existing for above-mentioned prior art, it is an object of the invention to provide a kind of wood containing native compound
Material preservative, it is to be compounded the composition of two kinds of different structures, the different mechanism of action, and timber is played with antiseptical effect.
For realizing the purpose of the present invention, Cyanogramide is compounded by inventor with scopolamine methobromide, for wood preservation.
To achieve these goals, the technical solution used in the present invention is:Timber preservative containing native compound, bag
Containing principle active component:Cyanogramide.Structural formula is as follows：
Described Cyanogramide is 1 with the ratio of the parts by weight of scopolamine methobromide:1-20:1.
Cyanogramide is 1 with the ratio of the parts by weight of scopolamine methobromide:1-20:1, effective ingredient accounts for gross weight
0.3%～10%..
Said composition also includes auxiliary formula：High molecular weight water soluble polymer, surfactant, organic solvent and water.
Described high molecular weight water soluble polymer is Copolyvidone, Polyvinylpyrrolidone, cinnamic acrylic ester are birdsed of the same feather flock together
Any one in compound.
Described organic solvent is normal propyl alcohol or n-butyl alcohol.
Effective ingredient 0.1-5%, high molecular weight water soluble polymer 0.6-4%, organic solvent 3-7%, excess water.
The present invention passes through for Cyanogramide and scopolamine methobromide compatibility to find having very well under specific ratio
Anti-mold effect, the particularly ratio in Cyanogramide and the parts by weight of scopolamine methobromide is 8-11:Between 1, its association
Apparent with anti-mold effect, and small toxicity, health environment-friendly.
Specific embodiment
Scopolamine methobromide, No. CAS:155-41-9, Shanghai Tao Su biochemical technology company limited etc. is all on sale.
The preparation method of compound Cyanogramide involved in the present invention is referring to document：Cyanogramide with a
new spiro[indolinone-pyrroloimidazole]skeleton from Actinoalloteichus
3708-11 page of cyanogriseus.Organic letters 2014 14 phase of volume 16.
Effect test:
Examination material Phyllostachys pubescens Mazei ex H.de Lebaie, originates from Anhui Province, life in 4～5 years, zero defect.It is processed into adjustable cast iron planes bamboo after raw bamboo removal bamboo green grass or young crops, Concretio silicea Bambusae seu schizostachyi
Bar, and under natural environment air dry to moisture content 12%～15%.In this experiment, bamboo wood is all processed into 40mm × 30mm × 6mm
The sample of (length × width x thickness).
Mycete:Aspergillus niger (AspergillusnigerV.Tiegh), Aspergillus citrimum (Penicilliumcitrintim
Thom), strain is provided by INST OF WOOD INDUDTRY CHINESE.
Experimental facilitiess
MJX-8503 Intelligent culture case, BCL-1360-B type superclean bench etc.
Bamboo wood sample in different medicinal liquids normal temperature dipping process when, according to process time 3min according to Soaking.
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 medicinal liquid and makes its liquid level
Exceed sample material top 2cm.After taking-up, wipe the residual liquid of specimen surface.Blank control group sample sterilized water soaks.Each condition
Take 6 repeat samples, the sample after process is placed in ventilation, air dry 21 days.
Anti-mold effect is evaluated
With reference to national standard《The experimental technique of timber mycete and Stain fungi prevented and treated by antifungus agent》, the interior of detection process sample
Fungicidal properties.4 weeks after sample connects bacterium interior, and the killed value of sample of every 3 days observed and recordeds and specimen surface go mouldy
Degree, and the killed value of reference sample.
| The degree that specimen surface goes mouldy | The examination bacterium infection killed value of area |
| Specimen surface no mycelia | 0 |
| Specimen surface infects area ＜ 1/4 | 1 |
| Specimen surface infects area 1/4～1/2 | 2 |
| Specimen surface infects area 1/2～3/4 | 3 |
| Specimen surface infects area ＞ 3/4 | 4 |
Medicament to the preventing efficiency computing formula of mycete is:
In E=(1-Dt/D0) × 100% formula:E is preventing efficiency (%)；Dt is the averagely killed value of chemicals treatment sample；
D0 is the averagely killed value of untreated control sample,
After indoor mould proof experiment in 4 weeks, variable concentrations process sample and the preventing efficiency of mycete are shown in Table.
The auxiliary formula of medicament is：Copolyvidone 2%, normal propyl alcohol 3%, excess water.
A is Cyanogramide, and B is scopolamine methobromide.

By experimental result it can be seen that single Cyanogramide and scopolamine methobromide have certain anti-mold effect,
But effect is not notable, substantial amounts of test shows only Cyanogramide:Scopolamine methobromide (8-11:1) ratio for
The prevention effect of mycete is good, and other ratio groups all notable it is seen that Cyanogramide:Scopolamine methobromide is in 8-11:When 1
Collaborative antiseptic effect substantially, has and significantly improves.
