Description
Technical field
The invention belongs to Yu Haiyang nontoxic biological anti-soil technology field, relate in particular to a kind of nontoxic and low toxicity novel antifouling coating that marine life is grown that suppresses on marine structure, more particularly, relate to and use the Chinese medicinal materials Galla Chinensis extract as marine antifoulant, preparation novel antifouling coating prevents halobiontic stained.
Background technology
Marine biofouling is meant the disadvantageous effect that the biological attachment on marine structure surface causes the performance of soaking extra large material.Because marine structure is long-term and contact with sea water, its surface becomes the carrier that marine organisms adhere to, grow and causes biodeterioration, and marine biofouling can cause that material corrosion strengthens, the boats and ships load increases the weight of, the speed of a ship or plane slows down even disturb sonar signal, blocks maritime pipeline, has a strong impact on harm such as aquaculture.Preventing and kill off marine biofouling method commonly used has: electrolysis anti-soil, antifouling, the poisonous antifouling paint of low surface energy are antifouling.Wherein poisonous antifouling paint mainly is to utilize coating to add deleterious stain control agent as carrier, is painted on the bottom, naval vessel or soaks extra large works surface, thereby kill, suppress biological attachment, reaches the purpose of preventing and kill off biodeterioration.
Therefore, marine antifoulant is the key ingredient of antifouling paint, is the key factor of decision antifouling property.For many years, the marine antifoulant of people's use mainly contains toxicity organotin (as tributyl tin, triphenyltin), Red copper oxide, biological biocide etc.Be developed into the seventies in 20th century since tributyl tin (TBT) antifouling paint,, be subjected to the warm welcome of whole world shipbuilding and shipping sector because organotin has broad spectrum toxicity, the long and low cost and other advantages of effect of antifouling phase.But it is found that to the beginning of the eighties organotin toxicity degradation period that this coating disengages is very long, can be deposited on ooze for a long time and be accumulated in the biology, cause environmental pollution and problem such as accumulation in vivo, make conch that the sex mutation take place as it, the duricrust attenuation of Crustacean, even the marine life of breaking-up aquafarm etc.The organo-tin compound of biological accumulation has jeopardized the mankind itself by food chain, causes in the world to pay much attention to for this reason.International Maritime Organizaton (IMO) has required to ban use of organotin as marine antifoulant from January 1st, 2003.On all boats and ships, abolish the organotin antifouling paint fully on January 1st, 2008.Now people to use maximum be the antifouling paint of Red copper oxide as stain control agent, because the toxicity of Red copper oxide antifouling paint is not as organotin coating, therefore, people are a large amount of Red copper oxide that add in coating, content is equivalent to topple over a large amount of metallic coppers up to 60-70% in the ocean.So also there is the serious environmental pollution problem in the Red copper oxide antifouling paint.Simultaneously, on November 10th, 2004, China is come into force dichlorodiphenyl trichloroethane (DDT about the Convention of Stockholm of persistence pollutent, dichloro-diphenyl-trichloroethane) etc. biocide and sterilant will be eliminated in 10 years, and this biological biocide also can't use as marine antifoulant.Because the poisonous stain control agent severe contamination marine eco-environment, even jeopardize the mankind, old friends need the marine antifoulant and the antifouling paint of the nontoxic or low toxicity of development of new badly.
In recent years, each state is all in the substitute of setting about studying poisonous stain control agents such as organotin, Red copper oxide, and effort searching active substance from marine organism is used to study novel nontoxic or low toxicity stain control agent.Since the eighties in 20th century, external from marine lifes such as marine bacteria, marine alga, coral, sponge separation and Extraction obtain hundreds of active substance extracts with antifouling ability, and measured the anti-fouling activity of different extracts.Steinberg etc. extract the extract of a series of furanone gamma lactones by name from Australian sea grass Delisea pulchra, can prevent the stained of marine bacteria; Rittschof and Gerhart etc. utilize the furanone gamma lactone as the Nantural non-toxic stain control agent, study its retarding effect that marine organisms larva is adhered to (USPatent 5248221).Denmark Schneider of BioLocus company limited and the Allermann possibility of biological enzyme as stain control agent in the antifouling paint.Biological enzyme adds coating and carries out the extra large link plate of reality, has only the barnacle of only a few to adhere to after 6 months.EP 478195 (Egan etc.) discloses the research as stain control agent of some medicine and agricultural chemicals mycocide dihydropyridazinone and pyridazinone compound, CN 1189293A (Lu Mu and Haars Co., Ltd) utilizes pyridazinone as marine antifoulant, they are applied to dihydropyridazinone and pyridazinone compound on the marine structure, are used to suppress marine organisms and adhere to.Because marine organisms are rich in halogen compounds, therefore, people utilize halogen-containing compound, carry out applied research (US 5,071,479) as carboxylamine 3-iodine propargyl N-butyl ester as marine antifoulant.
At present, at home, CN 1392208A (Wang Junyu) has carried out the research as stain control agent of the extract that utilizes the ocean sea tangle, and the fluoropolymer of this active substance and low surface energy come together to prevent or suppresses halobiontic and adhere to.The capsaicine that National Bureau of Oceanography two terrestrial plant that utilizes is extracted is as stain control agent, and the preparation antifouling paint is carried out nontoxic anti-soil technology research.People such as Wang Qiu (CN 1031387A) utilize living body biological such as ocean to vulcanize bacterium, as novel stain control agent, with the bacterial cell immobilization, utilize the meta-bolites of sulfuration bacterium to prevent sea marine organism pollution in base-material acrylic latex liquid.The activity of live bacteria is subjected to the influence of acrylic latex liquid bigger in this invention, is difficult for survival.
Up to now, the research of novel antifouling agent mainly concentrates on the extract that extracts the marine bioactivity material, or has the synthetic analogues of analog structure.Because marine organisms sampling difficulty, output and distribution is less, activity substance content lower (＜＜1%), extraction process complexity, cost an arm and a leg, product is difficult to practical application.And, do not see as yet and extract active substance from the Lu Sheng Chinese medicinal materials and prepare antifouling paint as stain control agent and be used for the research that marine anti-pollution decreases.
In general, marine antifoulant need join in the coating, and extra large body structure surface is being soaked in brushing, relies on different coating as carrier, could effectively prevent marine biofouling.Therefore, people utilize stain control agent to prepare a large amount of dissimilar antifouling paints.By stain control agent ooze out mechanism classification, marine antifouling coating can be divided into lysotype, contact-type, dispersion pattern and hydrolysis from the polishing type etc.; According to type, can be divided into pitch rosin Red copper oxide antifouling varnish, chlorinated rubber, ethene, vinylformic acid Red copper oxide antifouling varnish, chlorinated rubber, ethene, vinylformic acid organo-tin antifouling paint, organotin superpolymer antifouling varnish etc. again.
For example, CN 86103128A (Insternational Paint Public Ltd. Co.) discloses a kind of anti-fouling ship paint, wherein comprises by rosin and the resin that the aliphatic polyamines reaction that contains a primary amine or secondary amine group at least generates to make base-material.Described resin contains amidoamines or imidazoline group.The pigment that described antifouling paint comprises this base-material, marine antifoulant and solubleness is no more than 10ppm by weight in seawater.CN 1007902B (Kevin Pu Laodeluoke etc.) also discloses the prescription of antifouling paint, includes pigment, marine organisms kill agent (can be identical or different with pigment) and film forming base-material.
CN 1386799A (Zhou Yihao) discloses anti-fouling paint composition for ship and preparation method thereof, anti-fouling paint composition comprises high molecular polymer, inorganic poison material, organic malicious material, paint filler, various auxiliary agents etc., wherein be base-material with the high molecular polymer, inorganic poison material and organic poison material are formed compound poison material.The consumption of this compound base-material is the 28-36 weight part; The consumption of compound poison material is the 25-36.6 weight part; The consumption of color stuffing is the 22-32 weight part; Plasticizer dosage is the 3.5-5 weight part; The consumption of anti-settling agent is the 2-3 weight part; The consumption of mixed solvent is the 30-38 weight part.Above-mentioned each several part mixed set by step stirring evenly, can prepare antifouling paint.Anti-fouling paint of the present invention can improve work-ing life greatly, reduces the brushing number of times.
In a word, although the marine antifouling coating prescription is varied, antifouling paint mainly is made up of resin binder, different stain control agent, face (filling out) material and various auxiliary agents.Resin binder comprises multiple macromolecule resin material, as ethylene copolymer, Resins, epoxy, chlorinated rubber, acrylic resin, resol etc., the effect of resin binder mainly is a filming function, controls stain control agent simultaneously and slowly emits, and its consumption is generally at 10-40%.The consumption of stain control agent generally accounts for the 20%-70% of coating weight, and the main effect of stain control agent is to suppress, expel or kill the marine organisms that adhere to.Face (filling out) material mainly comprises zinc oxide, talcum powder, red iron oxide, silicon-dioxide, titanium dioxide, mica powder, lime carbonate etc., their consumption generally accounts for the 5%-40% of coating weight, the main effect of pigment is opacifying power, the reduction coating cost that improves coating, improves the mechanical properties and the rheological property of coating simultaneously.Sometimes as required, add certain auxiliary agent, as softening agent (as clorafin), solidifying agent, anti-settling agent (as hydrogenated castor oil), siccative etc., these auxiliary dosages are less, their effect mainly is to make execution of coating good, is convenient to use, and also helps to improve the performance of coating simultaneously.Generally also be added with limed rosin in the antifouling paint, consumption is generally 2-10%, and limed rosin can help disengaging of stain control agent.
Summary of the invention
Purpose of the present invention promptly is to propose a kind of nontoxic or low-toxicity anti-fouling coating that utilizes the preparation of Chinese medicinal materials gallnut solvent extract.
Technology contents of the present invention is: with dissimilar polarity solvent or non-polar solvent Turkey-galls is carried out separation and Extraction, the gallnut solvent extract of preparation adds in the coating as the stain control agent component as the stain control agent component or with Red copper oxide is composite, be prepared into nontoxic or low-toxicity anti-fouling coating, antifouling paint also includes resin, pigment, limed rosin and the various auxiliary agent as base-material.
In the coating of the present invention, resin binder adopts pitch system, acrylic resin, vinylite, chlorinated rubber is a resin, resol, its add-on is 10～40% of a coating weight, pigment adopts zinc oxide, talcum powder, red iron oxide, silicon-dioxide, titanium dioxide, mica powder, lime carbonate, its add-on is 5～40% of a coating weight, stain control agent is made of separately gallnut solvent extract or by gallnut solvent extract and Red copper oxide is composite constitutes, its add-on is 10～70% of a coating weight, and the add-on of limed rosin is 2～10% of a coating weight.
Turkey-galls is that positions different on specific seeds is to resist the product that the insect injury forms.Turkey-galls can be divided into the angle doubly, doubly two kinds in tripe, out-of-shape, difference in size is big, length range is at 2cm-15cm, great majority are at 4cm-6cm.Angle in the Turkey-galls doubly, tripe doubly all has good antibiotic, antiviral, antimycotic and anthelmintic action.
The gallnut solvent extract preparation
Gallnut solvent extract preparation technology flow process as shown in Figure 2.After the Turkey-galls fragmentation, soak into fully, keep solvent excessive, soaked 24-48 hour with solvent; Solvent for use can be divided into polar organic solvent and non-polar organic solvent two classes, polar organic solvent commonly used comprises: distilled water, methyl alcohol, ethanol, chloroform, acetone, acetonitrile, tetrahydrofuran (THF), N, the mixed solvent of dinethylformamide, dimethyl sulfoxide (DMSO) and above-mentioned solvent etc.Non-polar organic solvent commonly used comprises benzene, toluene, normal hexane, hexanaphthene, tetracol phenixin, sherwood oil, ethyl acetate etc.Because the extract productive rate of non-polar organic solvent is starkly lower than polar organic solvent,, more preferably use distilled water, ethanol, acetone so preferred polar organic solvent such as the chloroform/methanol used mixes solvent, ethanol, distilled water, acetone.
After in polar organic solvent, soaking certain hour after Turkey-galls is pulverized, solvent system reflux 10-24 hour; Filter then, get filtrate, utilize Rotary Evaporators, steam fully and remove organic solvent, can prepare body of paste and powder-product.General distilled water extraction thing obtains body of paste, and the extract of volatile organic solvent preparation prepares powder-product behind rotary evaporation, and this all is called as gallnut solvent extract.Utilize different solvent name nominating extracts, if utilize polar solvent such as acetone to prepare Galla Chinensis extract, then product is called the Turkey-galls acetone extract; If utilize non-polar solvent such as normal hexane to prepare Galla Chinensis extract, then product is called the Turkey-galls n-hexane extract.The gallnut solvent extract extraction process is simple relatively.According to the difference of solvent for use, the finished product are that body of paste or powder morphology exist.
Preliminary detection result through structural analysis instruments such as infrared spectra and nucleus magnetic resonance shows the mixture that gallnut solvent extract mainly is made up of tannin class (being also referred to as tannins) compound.
The possible antifouling mechanism of gallnut solvent extract is among the present invention: oozy forerunner's proteic substance solidified before the poly-hydroxy tannin compounds in the Galla Chinensis extract can make the protoplasma in the microbe, soft fouling organism and hard fouling organism adhere to, suppress the metamorphosis of biological larva, thereby reach the purpose that prevents that marine organisms from adhering to, and marine organisms are not had influence, thus reach can antifouling environmentally safe again purpose.
Gallnut solvent extract prepares nontoxic or low-toxicity anti-fouling coating
The preparation process of coating is deferred to the basic process of production of general coating, comprises the preparation of binder resin or selects for use, the adding of the grinding dispersion of solid materials such as face (filling out) material, stain control agent and dispersion, preparation coating, grinds repeatedly and obtain antifouling paint at last.
Gallnut solvent extract joins in the resin separately as stain control agent among the present invention, prepares a kind of new Nontoxic Antifouling Paint with face (filling out) material and limed rosin and various auxiliary agent.Wherein resin binder pitch system commonly used, acrylic resin, vinylite, chlorinated rubber are resin, resol etc., and the weight percent of resin is for being respectively 10%-40%.Different resin binders need use different solvents to dissolve, and solvent system commonly used comprises benzene-dimethylbenzene, dimethylbenzene-propyl carbinol, hexone-dimethylbenzene etc.The consumption of gallnut solvent extract is 20 to 70%wt amount (percentage ratio by weight) of coating weight meter, more preferably 20 to 45%wt amount; Face (filling out) material adopts zinc oxide, talcum powder, red iron oxide, silicon-dioxide, titanium dioxide, mica powder, lime carbonate, and its consumption accounts for the 5%-40% of coating weight.The consumption of limed rosin is 2-10%.The nontoxic antifouling paint color of preparation is grey or canescence.
The present invention uses gallnut solvent extract and Red copper oxide composite as stain control agent simultaneously, and the add-on of stain control agent is the 20-70% of coating weight, prepares a kind of novel low-toxicity anti-fouling coating.Wherein resin binder pitch system commonly used, acrylic resin, vinylite, chlorinated rubber are resin, resol etc., and the weight percent of resin is 10%-40%.Select proper solvent system, as benzene-dimethylbenzene, dimethylbenzene-propyl carbinol, hexone-dimethylbenzene etc., the ratio of Turkey-galls polar organic solvent extract and Red copper oxide is 75: 25-25: 75, preferred 60: 40-40: 60 amount.Face (filling out) material adopts zinc oxide, talcum powder, red iron oxide, silicon-dioxide, titanium dioxide, mica powder, lime carbonate, and its consumption accounts for the 5%-40% of coating weight.The consumption of limed rosin is 2-10%.The low-toxicity anti-fouling coating color of preparation is a garnet.
Because single stain control agent to the limitation of all marine fouling organism effects, so complex role can make the antifouling effect of two kinds of stain control agents replenish mutually, has wideer antifouling broad spectrum of activity.Simultaneously, composite by gallnut solvent extract and Red copper oxide stain control agent under the prerequisite that does not influence antifouling property, reduces the consumption of Red copper oxide as far as possible, reduces pollution and harm to environment.
The extra large link plate of the reality of novel antifouling coating detects
Real extra large link plate detects and carries out antifouling paint shallow sea soak test by standard GB 5370-85 method, adopts 150 * 300 * 3mm mild steel plate, and behind the brushing rust-inhibiting paint, brushing gallnut solvent extract antifouling paint is made the antifouling varnish model again.The antifouling varnish model is placed between the degree of depth 0.2～2m of coastal waters the routine observation record.Initial per week, every month subsequently routine observation write down the adhesion condition of antifouling coating surface marine biology, compare with the model of not brushing antifouling varnish simultaneously.During observation, should remove, to eliminate edge effect along template edge 20mm.
When experiment model fouling organism area coverage be less than contrast model 1-5% for good slightly; Be less than 5-10% for well; Equal to identical; More than 1-5% for poor slightly; More than 5-10% is poor.When the fouling organism area coverage of test piece greater than 10%, answer termination test, and as final test-results.
Gallnut solvent extract as the nontoxic antifouling paint of stain control agent preparation, has carried out the shallow sea board experiment separately among the present invention, and real extra large experimental result showed that it had tangible initial stage anti-fouling effect in 3 months.
The composite antifouling paint of gallnut solvent extract and Red copper oxide among the present invention as the stain control agent preparation, carried out the shallow sea board experiment, the result shows that this low-toxicity anti-fouling coating has tangible anti-fouling effect, the antifouling phase imitates apparently higher than the aforesaid nontoxic antifouling paint of the present invention, near the result of use of poisonous antifouling paint.By the compound proportion of reasonable adjustment gallnut solvent extract and Red copper oxide, this novel low-toxicity anti-fouling coating can reach and can effectively prevent marine biofouling, can reduce the Red copper oxide consumption again, reduces and pollutes, and has tangible environmental protection effect.
