Abstract
The invention provides application of a Eupatorium adenophorum extract as an anti-fouling paint antifoulant. The method takes a 10 to 100 percent aqueous solution of methanol, ethanol, ethyl acetate, ligroine, and chloroform as an extracting solvent to extract a Eupatorium adenophorum active ingredient which is added into anti-fouling paint and is applied as an antifoulant.
Description
Technical field
The present invention adopts 10%-100% methyl alcohol, ethanol, ethyl acetate, sherwood oil and chloroform water solution to go out the Hemp Eupatorium activeconstituents as extracting solvent extraction, uses as anti-fouling paint antifoulant by processing the back.
Background technology
Hemp Eupatorium (Eupatorium adenophorum Spreng) is a composite family Eupatorium per nnial herb, originate in Mexico, import the Yunnan Province of China south into from Burma and Vietnam before and after the 1950's, because of its growth and fecundity extremely strong, in Yunnan Province and peripheral many areas spread.Because it is herded sideline production to agricultural and has brought serious harm the destruction of ecotope.
In view of Hemp Eupatorium has become one of the most serious exotic invasive species of China's harm, various places are when the Hemp Eupatorium that tightens control spreads measure, and the numerous and confused research that launches its comprehensive utilization is tried hard to change harmful to treasure.Hu Jue etc.
1Studied the production potential that biogas continuously ferments after the Hemp Eupatorium pre-treatment.Yang Yazhou
2On basis to Hemp Eupatorium chemical constitution, fibre shape and surface free energy research, to the processing parameter of Hemp Eupatorium medium density fibre board (MDF) and studies show that of physical and mechanical property and influence factor thereof, the Hemp Eupatorium medium density fibre board (MDF) that experiment condition is made down, through suitably regulating processing condition, all can the be up to state standards requirement of indoor type medium density fibre board (MDF) of some performance index.Tian Guoting etc.
3Utilize Hemp Eupatorium as raw material cultivation the edge of a field mushroom, utilize straw and cotton seed hulls to compare simultaneously for raw material cultivation the edge of a field mushroom, result of study shows, in the culture medium prescription of generation material grog cultivation the edge of a field mushroom, the prescription effect that with the Hemp Eupatorium is main raw material is best, and the straw substratum of biology efficiency ratio contrast on average increases production more than 80%.Sun Qiming
4Studied the applied research of Hemp Eupatorium as wild organic fertilizer.Yang Yonghong etc.
5With the Hemp Eupatorium is raw material, produces Xylitol with the method for microbial fermentation.Ou Yanghua, Wang Houde adopt special microbial fermentation detoxification, mannosans detoxification, inorganic absorption detoxification, herbal medicine to detoxify and health care combines, and Deco method is developed as the plant protein fodder raw material of success with Hemp Eupatorium, and has applied for patent
6And the activeconstituents that we extract Hemp Eupatorium among the present invention is used as anti-fouling paint antifoulant.
Antifouling varnish is a kind of special coating that is coated on hull bottom and ocean underwater facility, and general coating is contained on the bottom anticorrosive paint, is in outermost layer.Its main effect is that the modes such as the oozing out of material, diffusion or hydrolysis of poisoning by paint film progressively discharge the poison material, reaches to prevent that marine attaching organism is attached to the purpose of hull bottom or ocean underwater facility.
More than 2000 kind of fouling organism arranged in the ocean, and majority is lived in offshore sea waters such as seashore and bay.The larva of fouling organism and spore can floatingly move about, develop into just to adhere to behind the certain phase and settle down, stained Offshore Units, for example hull, buoy, bridge pier, harbour, net cage and netting gear etc., its main harm comprises the resistance that increases boats and ships, block pipeline, quicken metallic corrosion, make instrument and the rotation machine is malfunctioning, to the influence of acoustic instrument and to the influence of water industry etc., be difficult to estimation by the loss that biodeterioration caused.The marine anti-pollution technology is to be used to prevent that marine organisms are stained to adhering to of Offshore Units, be started in the research of ship pollution prevention coating, and antifouling with poison material release type be the major technique approach, by stain control agents such as releasable copper, tin, mercury, lead in the coating, forming around material has the concentration of poisons layer of toxic action to marine plant spore and marine animal larva, thereby reaches anti-fouling effect.Yet, this type of antifouling paint in use, part toxic agent (as organotin, DDT) can cause the seawater water pollution, causes biomutation, jeopardizes marine food chain, and marine ecology balance and human health are had potential harm.
Consider that from environmental angle people wish to use nuisanceless anti-soil technology, realize preventing and kill off marine fouling organism.So we are developed as anti-fouling paint antifoulant with Eupatorium adenophorum extract.

Summary of the invention
The objective of the invention is to develop new anti-fouling paint antifoulant, this method is starting raw material with the Hemp Eupatorium, adopt 10%-100% methyl alcohol, ethanol, ethyl acetate, sherwood oil and chloroform water solution to go out the Hemp Eupatorium activeconstituents, use as anti-fouling paint antifoulant by processing the back as extracting solvent extraction.The Hemp Eupatorium poisonous weeds can be used by oneself, change harmful to treasure, and what opened is eco-friendly stain control agent, can not pollute environment.
The objective of the invention is to realize by the following technical solutions:
Step of the present invention is as follows:
1) bright cauline leaf of Hemp Eupatorium and dry cauline leaf are ground into powder;
2) with the Hemp Eupatorium powder that obtains in the step 1), add methyl alcohol or ethanol or ethyl acetate or sherwood oil or the chloroform water solution of 10%-100%, behind the immersion 48h, solids removed by filtration behind the employing vacuum distillation recovered solvent, obtains sticky shape dark solution;
3) adopt vacuum freezing drying device with 2) in the solution drying that obtains;
4) with 3) in the dry thing that obtains add to according to a certain percentage in the antifouling varnish and use as stain control agent.
Annex: Eupatorium adenophorum extract is as the anti-fouling paint antifoulant determination of activity
1. coating (antifouling varnish) is filled a prescription
1), superpolymer: be combined into by physics and chemistry institute of Chinese Academy of Sciences coating, be the polymer of methacrylic acid and butyl methacrylate copolymerization generation, add-on (w/w) is 20% of total coating.
2), mineral dye ZnO 5%
3), inorganic Fe2O3 pigment does not add
4), solvent: burnt No. 200 solvents of dimethylbenzene and matchmaker, about 20-25%
5), permeate agent SiO2 a small amount of (2-4%)
6), permeate agent (1-2%)
7), tensio-active agent (0.5-1.0%)
8), biopolymer rosin (0.5-1.0%)
9), purple stem boneset extract 10% (w/w)
Said components is ground in ball mill, till graininess and other rerum naturas all satisfy GB and require, generally will grind 25-30 hour (room temperature)
2. board experiment
1) coating (each component of coating) is taken to the Xiamen boats and ships and detect authorized by state unit (725) check
2) coating is coated onto on the link plate (25 * 15cm2)), after the drying, goes into to do under the environment of 1.5 meters in seawater antifouling test (whether have seashells animal, barnacle, Ascidian, oyster, mussel, lime worm etc. adhere to onboard, adhered area＞8% lost efficacy if detecting).
3. test-results
Go into seawater after one month link plate intact; The link plate reverse side is intact after two months.
From experimental result as can be seen, do not adding (20%) under the Red copper oxide condition, eupatorium adenophorum extracting solution has good repellent action to marine organisms.
