Abstract
The invention discloses a kind of timber preservative containing compound HelikaurolideA, HelikaurolideA and Lathyrol, the ratio between parts by weight of HelikaurolideA and Lathyrol are 1:1‑30:1.The present invention is 23 25 particularly in the ratio between parts by weight of HelikaurolideA and Lathyrol by the way that HelikaurolideA and Lathyrol compatibility to be had found to have good wood mould effect under specific ratio:Between 1, it cooperates with anti-mold effect effect apparent.
Description
Technical field
The present invention relates to a kind of preservative, is specifically a kind of timber preservative containing compound HelikaurolideA,
Belong to agricultural technology field.
Background technology
Up to the present, the most commonly used method for preventing foxiness is to use chemical agent anti-corrosion, preservative in production and
Leakage and exudation during use, and the discarded and burning of preservative-treated timber can all adversely affect environment, and
Endanger the health of the mankind.Since environmental problem has been to be concerned by more and more people, also become the key of selection preservative.
It is currently used it is most be waterborne-type preservation, account for preservative uses total amount 3/4.Since single preservative resists
Domestomycetes, the scope of worm are narrow, are typically now mixed in a certain ratio two or more preservatives, can not only overcome
Shortcoming 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.Since traditional preservatives are there are many deficiencies, people are forced to grind
Study carefully and find to person poultry harmless, environmentally safe, only poisonous to microorganism new food preservative.More include is studied at present
Water miscible alkylammonium class compound (AAC), the molten alkylamine copper (ACQ) of ammonia, boride, cupric dimethyldithio carbamate
(CDDC) and oil-soluble Bravo (CTL), organic iodide (IPBC) etc..It is nontoxic, high for the essence of wood preservation, exploitation
Effect and practical wood preservation method, reduce environmental pollution, to protection human ecological environment and make full use of existing resource meaning
It is far-reaching.
HelikaurolideA is published in Helikaurolides A-D with a Diterpene- first
Sesquiterpene Skeleton from Supercritical Fluid Extracts of Helianthus annuus
L.var.AriannaOrg.Lett.,2015,17(19),4730–473.It is separated from sunflower with brand-new
The compound of skeleton,
Have it is found by the applicant that HelikaurolideA coordinates with Lathyrol under certain proportion for wood preservation
There is the effect of 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 one kind to contain compound
The timber preservative of HelikaurolideA, it is to be compounded the component of two kinds of different structures, the different mechanisms of action, to wood
Material plays the role of corrosion-resistant.To achieve the object of the present invention, inventor compounds HelikaurolideA and Lathyrol,
For wood preservation.
To achieve these goals, the technical solution adopted by the present invention is:Wood containing compound HelikaurolideA
Material preservative, includes principle active component:HelikaurolideA.Structural formula is as follows：
The ratio between the HelikaurolideA and the parts by weight of Lathyrol are 1:1-30:1.
The ratio between parts by weight of HelikaurolideA and Lathyrol are 1:1-30:1, active ingredient accounts for gross weight
0.3%~10%..
Said composition further includes auxiliary formula：High molecular weight water soluble polymer, surfactant, organic solvent and water.
The high molecular weight water soluble polymer is copolyvidone, polyvinylpyrrolidone, cinnamic acrylic ester are birdsed of the same feather flock together
Any one in compound.
The organic solvent is normal propyl alcohol or n-butanol.
Active ingredient 0.1-5%, high molecular weight water soluble polymer 0.6-4%, organic solvent 3-7%, excess water.
HelikaurolideA and Lathyrol compatibility by being had found have very by the present invention under specific ratio
Good anti-mold effect, is 23-25 particularly in the ratio between parts by weight of HelikaurolideA and Lathyrol:Between 1,
It cooperates with anti-mold effect apparent, and small toxicity, health environment-friendly.
Embodiment
Lathyrol, No. CAS:34420-19-4, Chengdu Zhi Biaohuachun Bioisystech Co., Ltd etc. is on sale.
The preparation method of compound HelikaurolideA involved in the present invention is referring to document：(Helikaurolides A–
D with a Diterpene-Sesquiterpene Skeleton from Supercritical Fluid Extracts
of Helianthus annuus L.var.AriannaOrg.Lett.,2015,17(19),4730–473)。
Effect test:
Material willow is tried, originates from Jiangsu Province, life in 5~10 years, zero defect.Adjustable cast iron planes willow bar is processed into peeling, and in natural ring
Gas is done to moisture content 12%~15% under border.Willow is all processed into 40mm × 30mm × 6mm (length × width x thickness) in this experiment
Sample
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..
Every group has 22 willow samples in different liquids during normal temperature dipping processing, according to processing time 3min according to normal
Press infusion process.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, various concentrations processing sample is shown in Table the preventing efficiency of mould.
The auxiliary formula of medicament is：Polyvinylpyrrolidone 2%, n-butanol 5%, excess water.
A is HelikaurolideA, and B is Lathyrol.
By experimental result it can be seen that single HelikaurolideA and Lathyrol have certain mould proof effect
Fruit, but effect is not notable, substantial amounts of experiment shows only HelikaurolideA and Lathyrol 23-25:1) ratio
Example is good for the prevention effect of mould, and other ratio groups are not notable, it is seen that HelikaurolideA and Lathyrol
In 23-25:Cooperate with anti-corrosion effect obvious when 1, there is significant progress.
