Description
Oppfinnelsen vedrører anvendelse av en vulkaniserbar The invention relates to the use of a vulcanizable
blanding for belegning av marine konstruksjoner. mixture for coating marine structures.
Overflater av marine konstruksjoner, så som skipsskrog og skipsbøyer, må beskyttes mot tilsmussing av organismer, så som gress, alger, igler, rørormer, sepula, østers, ascidia, bryozoa og lignende, og denne tilsmussing foregår når den marine kon-struksjon er nedsenket i sjøvann. Organismene klebes til overflaten, og ved at de gir høyere vekt og øket friksjonsmotstand fører de til lavere hastigheter og høyere brenselsforbruk for skipene. For å unngå nødvendigheten av hyppig fjerning av de tilsmussende organismer er det blitt utviklet belegningsprodukter for mairinkonstruksjoner som hemmer fastklebingen av organismene til marinkonstruksjonene. Disse belegningsprodukter omfatter malinger som inneholder giftige substanser basert på metaller, så som kobber, tinn, bly, kvikksølv og arsen. Den tidsperiode som disse malinger kan hindre tilsmussing er svært begrenset, og dessuten kan man ved anvendelse av disse belegningsprodukter støte på problemer med hensyn til giftighet. Surfaces of marine constructions, such as ship hulls and ship buoys, must be protected against fouling by organisms, such as grass, algae, leeches, tube worms, sepula, oysters, ascidia, bryozoa and the like, and this fouling takes place when the marine construction is submerged in seawater. The organisms stick to the surface, and because they add more weight and increased frictional resistance, they lead to lower speeds and higher fuel consumption for the ships. In order to avoid the necessity of frequent removal of the fouling organisms, coating products have been developed for marine structures which inhibit the sticking of the organisms to the marine structures. These coating products include paints that contain toxic substances based on metals, such as copper, tin, lead, mercury and arsenic. The period of time during which these paints can prevent fouling is very limited, and furthermore, when using these coating products, problems with regard to toxicity may be encountered.
Belegninger hvorpå organismene har vanskelig for å til-klebes, så som silikonharpikser og silikongummier, er også Coatings to which the organisms have difficulty adhering, such as silicone resins and silicone rubbers, are also
blitt angitt å ha antitilsmussende egenskaper, men de synes ikke å gi en avgjørende løsning på tilsmussingsproblemet. have been reported to have antifouling properties, but they do not seem to provide a definitive solution to the fouling problem.
Det er nå funnet at belegningsblandinger som omfatter en vulkanisert silikongummi og en fluid metall-fri og silisium-fri organisk forbindelse, fremviser svært attraktive antitilsmuss-ings-egenskaper og friksjons-forbedrende egenskaper. It has now been found that coating compositions comprising a vulcanized silicone rubber and a fluid metal-free and silicon-free organic compound exhibit very attractive anti-fouling and friction-enhancing properties.
I henhold til oppfinnelsen anvendes en vulkaniserbar blanding, omfattende en vulkaniserbar silikongummi og en metall-fri og silisium-fri organisk forbindelse som er flytende ved den temperatur som er rådende i sjøvann, og som er valgt blant et polyolefin med molekylvekt opp til 5000, en smøreolje, According to the invention, a vulcanizable mixture is used, comprising a vulcanizable silicone rubber and a metal-free and silicon-free organic compound which is liquid at the temperature prevailing in seawater, and which is selected from a polyolefin with a molecular weight of up to 5000, a lubricating oil,
en karboksylsyreester og en fosforsyreester, for belegning av marine konstruksjoner. a carboxylic acid ester and a phosphoric acid ester, for coating marine structures.
Vulkaniserte silikongummier kan fremstilles av silikongummier som er sterkt lineære høymolekylære organo-siloksan-polymerer bestående vesentlig av alternerende atomer av silisium og oksygen som en polymer ryggrad med organiske grupper festet til silisiumatomene på den polymere ryggrad. Vulkanisert silikongummi kan fremstilles ved varmeherding med forskjellige katalysatorer (så som peroksyder) eller ved stråleherding av en silikongummi som for eksempel vesentlig består av et polydihydrokarbylsiloksan, hvor alle eller en dominerende del av hydrokarbylenhetene er metyl-enheter, og resten er vinyl- og/eller fenyl-enheter. Vulcanized silicone rubbers can be made from silicone rubbers which are highly linear high molecular weight organo-siloxane polymers consisting essentially of alternating atoms of silicon and oxygen as a polymeric backbone with organic groups attached to the silicon atoms on the polymeric backbone. Vulcanized silicone rubber can be produced by heat curing with various catalysts (such as peroxides) or by radiation curing of a silicone rubber which, for example, essentially consists of a polydihydrocarbylsiloxane, where all or a dominant part of the hydrocarbyl units are methyl units, and the rest are vinyl and/or phenyl units.
Vulkaniserte silikongummier kan også fremstilles ved omgivelsenes temperatur ved å vulkanisere silikongummier som inneholder silanol-endegrupper (de såkalte RTV-gummier). Alle eller en overveiende del av de organiske grupper i RTV-gummiene er hydrokarbyl-grupper (spesielt metyl-grupper), og de gjenværende kan være etyl-, fenyl- eller substituerte hydrokarbyl-grupper, så som klorfenyl-, fluorpropyl- eller cyanoetyl-grupper. Anvendelse av RTV-gummi er foretrukket i de vulkaniserbare silikongummier som anvendes ved utførelse av oppfinnelsen. For å fremstille en vulkaniserbar silikon-gummi fra en RTV-gummi foreligger to fremgangsmåter. Vulcanized silicone rubbers can also be produced at ambient temperature by vulcanizing silicone rubbers containing silanol end groups (the so-called RTV rubbers). All or a predominant part of the organic groups in the RTV rubbers are hydrocarbyl groups (especially methyl groups), and the remaining can be ethyl, phenyl or substituted hydrocarbyl groups, such as chlorophenyl, fluoropropyl or cyanoethyl groups. The use of RTV rubber is preferred in the vulcanizable silicone rubbers used in carrying out the invention. There are two methods for producing a vulcanizable silicone rubber from an RTV rubber.
Ved det såkalte to-pakke-system kan RTV-gummien blandes med et tverrbindingsmiddel, vanligvis etylsilikat, og om ønskes med fyllstoffer, pigmenter etc. Like før anvendelsen blir det blandet inn en egnet katalysator (vanligvis et organisk tinnsalt, så som dibutyl-tinn-dilaurat eller stanno-oktoat), og tverrbindingen begynner øyeblikkelig. Det er også mulig å tilsette tverrbindingsmidlet og/eller andre ønskede materialer delvis eller helt sammen med katalysatoren til RTV-gummien som skal vulkaniseres. Det kan også være løsningsmidler til stede i én av eller i begge de to kompo-nenter (RTV-gummi og katalysator) som skal blandes. With the so-called two-pack system, the RTV rubber can be mixed with a cross-linking agent, usually ethyl silicate, and if desired with fillers, pigments, etc. Just before use, a suitable catalyst is mixed in (usually an organic tin salt, such as dibutyl tin -dilaurate or stannous octoate), and the cross-linking begins immediately. It is also possible to add the cross-linking agent and/or other desired materials partially or completely together with the catalyst to the RTV rubber to be vulcanized. There may also be solvents present in one or both of the two components (RTV rubber and catalyst) to be mixed.
Ved én-pakke-systemet anvendes det en RTV-gummi som er omsatt med en forbindelse med den generelle formel RSiX^ i hvilken R betyr hydrokarbyl (vanligvis metyl) og X en hydroksyl-gruppe eller en gruppe som inneholder en hydrolyserbar oksygen-binding (f.eks. acetoksy) eller en aminogruppe eller en gruppe som inneholder en hydrolyserbar nitrogen-binding (f.eks. acylamido eller ketoksin) eller et annet reaktivt punkt. Løsningsmidler, katalysatorer og/eller fyllstoffer, pigmenter, etc. kan også være tilstede i én-pakkesystemet, hvilket må holdes beskyttet fra fuktighet. Det foregår tverrbinding når pakken kommer i kontakt med vann, f.eks. i kontakt med en fuktig atmosfære. In the one-pack system, an RTV rubber is used which has been reacted with a compound of the general formula RSiX^ in which R means hydrocarbyl (usually methyl) and X a hydroxyl group or a group containing a hydrolyzable oxygen bond ( eg acetoxy) or an amino group or a group containing a hydrolysable nitrogen bond (eg acylamido or ketoxin) or another reactive point. Solvents, catalysts and/or fillers, pigments, etc. may also be present in the one-pack system, which must be kept protected from moisture. Cross-linking takes place when the package comes into contact with water, e.g. in contact with a humid atmosphere.
Den fluide metall-frie og silisium-frie organiske forbindelse (senere også kalt den fluide organiske forbindelse) er en forbindelse, eller en blanding av forbindelser, som er flytende ved den temperatur som er rådende i sjøvann. Det er svært passende at den er forlikelig med silikongummien, hvilket betyr at det kan fremstilles en homogen blanding av silikongummien og den mengde av fluid organisk forbindelse som skal inkorporeres. Det vil ikke foregå noen betydelig korttids-faseseparering før vulkaniseringen, selv om det kan foregå en sakte frigjøring av den fluide organiske forbindelse fra den vulkaniserte silikon-gummi, spesielt eksudasjon, og dette blir ansett å være fordel-aktig. Egnede fluide organiske forbindelser er som nevnt lav-molekylære polyolefiner med en molekylvekt opptil ca. 5000, så som etylen-propylen-kopolymerer, og spesielt polyisobuten, fortrinnsvis med molekylvekt på 300-500. The fluid metal-free and silicon-free organic compound (later also called the fluid organic compound) is a compound, or a mixture of compounds, which is liquid at the temperature prevailing in seawater. It is very convenient that it is compatible with the silicone rubber, which means that a homogeneous mixture of the silicone rubber and the amount of fluid organic compound to be incorporated can be prepared. There will be no significant short-term phase separation prior to vulcanization, although there may be a slow release of the fluid organic compound from the vulcanized silicone rubber, especially exudation, and this is considered beneficial. Suitable fluid organic compounds are, as mentioned, low-molecular polyolefins with a molecular weight of up to approx. 5000, such as ethylene-propylene copolymers, and especially polyisobutene, preferably with a molecular weight of 300-500.
Fluide organiske forbindelser som også kan anvendes, er smøreoljer, så som tekniske hvit-oljer. Fluid organic compounds that can also be used are lubricating oils, such as technical white oils.
Den fluide organiske forbindelse kan også bestå av forbindelser som er angitt som myknere. Eksempler på myknere er estere av karboksylsyrer, f.eks. av fettsyrer, så som laurin-syre og stearinsyre, estere av dikarboksylsyrer, så som adipin-syre, azelainsyre, sebacinsyre, ftalsyre (f.eks. dinonylftalat). Esterne kan også omfatte hetero-atomer og/eller hetero-grupper i sine hydrokarbonkjeder, hvilke f.eks. kan inneholde hydroksyl-grupper og/eller halogenatomer, så som klor, og spesielt fluor, eller bestå av perfluorerte karbonkjeder. The fluid organic compound can also consist of compounds which are designated as plasticizers. Examples of plasticizers are esters of carboxylic acids, e.g. of fatty acids, such as lauric acid and stearic acid, esters of dicarboxylic acids, such as adipic acid, azelaic acid, sebacic acid, phthalic acid (e.g. dinonyl phthalate). The esters can also include hetero atoms and/or hetero groups in their hydrocarbon chains, which e.g. may contain hydroxyl groups and/or halogen atoms, such as chlorine, and especially fluorine, or consist of perfluorinated carbon chains.
Den annen mykner-type som kan anvendes, er estere av fosforsyre (f.eks. trikresylfosfat). The other type of plasticizer that can be used is esters of phosphoric acid (eg tricresyl phosphate).
Når den fluide organiske forbindelse bare er forlikelig med silikongummien i mengder som ikke er tilstrekkelig til at det med sikkerhet oppnåes anti-tilsmussings-aktivitet i en lang periode, er det svært passende at den fluide organiske forbindelse er inkorporert i silikon-gummien i en innkapslet form. Det materiale som anvendes til innkapslingen må være sakte gjennomtrengelig for den innkapslede fluide organiske forbindelse, slik at det opprettholdes en lav konsentrasjon av denne forbindelse i silikon-gummien, som muliggjør eksudasjon av den fluide organiske forbindelse fra silikon-gummien. Innkapslingsmaterialet består svært passende delvis eller fullstendig av en polymer, og kan f.eks. være en silikon-gummi eller en annen type av gummimateriale, eller det kan være basert på polyester-, polyuretan- eller cellulose-derivater eller hvilket som helst annet egnet polymert materiale som tillater en sakte frigjøring av det innkapslede fluid inn i silikon-gummien. When the fluid organic compound is only compatible with the silicone rubber in amounts insufficient to reliably achieve antifouling activity for a long period of time, it is highly appropriate that the fluid organic compound is incorporated into the silicone rubber in an encapsulated shape. The material used for the encapsulation must be slowly permeable to the encapsulated fluid organic compound, so that a low concentration of this compound is maintained in the silicone rubber, which enables exudation of the fluid organic compound from the silicone rubber. The encapsulation material very conveniently consists partially or completely of a polymer, and can e.g. be a silicone rubber or another type of rubber material, or it may be based on polyester, polyurethane or cellulose derivatives or any other suitable polymeric material that allows a slow release of the encapsulated fluid into the silicone rubber.
Selvsagt kan fortynningsmidler for den fluide organiske forbindelse være til stede i belegningsblandingene som anvendes i henhold til oppfinnelsen. Mindre effektive fluide forbindelser kan anvendes som fortynningsmidler eller bærere som inneholder bare relativt små konsentrasjoner av de mer foretrukne fluider. Of course, diluents for the fluid organic compound can be present in the coating mixtures used according to the invention. Less effective fluid compounds can be used as diluents or carriers containing only relatively small concentrations of the more preferred fluids.
Om ønskes kan det også inkorporeres materialer som øker styrken til silikon-gummien. Som eksempler kan nevnes fibrøse materialer (f.eks. glassfibre eller nylonfibre) og pulverformede polymerer, så som polytetrafluoretylen. If desired, materials can also be incorporated that increase the strength of the silicone rubber. Examples include fibrous materials (e.g. glass fibers or nylon fibers) and powdered polymers such as polytetrafluoroethylene.
Mengden av fluid organisk forbindelse kan varieres innen vide grenser. Mengder fra 0,1 til 100 vektdeler pr. 100 vektdeler av vulkanisert silikon-gummi er svært egnet. The amount of fluid organic compound can be varied within wide limits. Quantities from 0.1 to 100 parts by weight per 100 parts by weight of vulcanized silicone rubber is very suitable.
Ved påføring av belegningsblandingen som omfatter den vulkaniserbare silikon-gummi og den fluide organiske forbindelse på overflaten av marinkonstruksjonen, behandles overflaten med en blanding som omfatter silikon-gummien som skal vulkaniseres og den fluide organiske forbindelse hvoretter silikon-gummien vulkaniseres in situ. Av denne grunn bør den fluide organiske forbindelse som skal anvendes, ha en slik struktur at den ikke, eller bare i en ubetydelig mengde, deltar i den omsetning som fører til tverrbinding av silikon-gummien for dannelse av en vulkanisert silikon-gummi. When applying the coating mixture comprising the vulcanizable silicone rubber and the fluid organic compound on the surface of the marine structure, the surface is treated with a mixture comprising the silicone rubber to be vulcanized and the fluid organic compound after which the silicone rubber is vulcanized in situ. For this reason, the fluid organic compound to be used should have such a structure that it does not, or only in an insignificant amount, participate in the reaction which leads to cross-linking of the silicone rubber to form a vulcanized silicone rubber.
Silikon-gummien og den fluide organiske forbindelse kan påføres på overflaten av marinkonstruksjonen på hvilken som helst passende måte, så som påstrykning, sprøyting og lignende. The silicone rubber and the fluid organic compound may be applied to the surface of the marine structure by any suitable means such as brushing, spraying and the like.
Den overflate som skal belegges i henhold til oppfinnelsen kan være blitt forbehandlet for å gi bedre fastklebing dertil av belegningsproduktet i henhold til oppfinnelsen, f.eks. ved sandblåsing og/eller påføring av et klebemiddel-sjikt. Det kan også være påført andre belegninger, f.eks. en anti-korroderende belegning og/eller en anti-grobelegning av tidligere kjent slag. Belegningsblandingene kan også omfatte metallholdige anti-gromidler av tidligere kjent slag. The surface to be coated according to the invention may have been pre-treated to provide better adhesion thereto of the coating product according to the invention, e.g. by sandblasting and/or applying an adhesive layer. Other coatings may also be applied, e.g. an anti-corrosive coating and/or an anti-pitting coating of a previously known type. The coating mixtures can also include metal-containing antifouling agents of a previously known type.
Det er foretrukket med blandinger som er vulkaniserbare ved omgivelsenes temperaturer. It is preferred to use mixtures that are vulcanizable at ambient temperatures.
EKSEMPLER EXAMPLES
Fiberglass-plater ble belagt med et konvensjonelt anti-rust-system og deretter med de anti-groblandinger som anvendes i henhold til oppfinnelsen, med en sjikt-tykkelse på 150-200 pm. De således oppnådde test-plater ble nedsenket i sjøvann ved Poole Harbour, og deres tilstand ble inspisert etter 3 og 12 måneder. Tilstanden til platene ble vurdert når de ble tatt ut av vannet og også etter vasking med vann ved lavt trykk. Denne vasking ble utført for å oppnå en indikasjon på den styrke som tilsmussingen ble fastholdt med, og den kan ansees å være i en viss grad analog Fiberglass plates were coated with a conventional anti-rust system and then with the anti-fouling compounds used according to the invention, with a layer thickness of 150-200 pm. The test plates thus obtained were immersed in seawater at Poole Harbour, and their condition was inspected after 3 and 12 months. The condition of the plates was assessed when they were taken out of the water and also after washing with water at low pressure. This washing was carried out to obtain an indication of the strength with which the soiling was retained, and it may be considered to be somewhat analogous
med de forhold som erfares med et skip som er i fart. with the conditions experienced with a ship in motion.
Platene ble vurdert etter en klassifisering av deres tilsmussingsgrad, og ved den endelige vurdering ble det lagt minst vekt på slim, og økende vekt via ugress-tilsmussing til krepsdyr-tilsmussing. The plates were assessed according to a classification of their degree of soiling, and in the final assessment the least weight was given to slime, and increasing weight via weed soiling to crustacean soiling.
Som det kan sees av tabellen fremviste platene i eksemplene 1-8 i henhold til oppfinnelsen etter vann-vasking, mindre tilsmussing enn plater behandlet med en konvensjonell anti-tilsmussings-maling (forsøk 9). As can be seen from the table, the plates in Examples 1-8 according to the invention after water washing showed less soiling than plates treated with a conventional anti-fouling paint (experiment 9).
SAMMENLIGNINGSEKSEMPEL COMPARISON EXAMPLE
Blanding: 100 vektdeler Silastic RTV 504 Mixture: 100 parts by weight Silastic RTV 504
20 vektdeler Dow Corning RTV Catalyst S 20 parts by weight Dow Corning RTV Catalyst S
Vurdering: 3 måneders neddypping, ingen behandling: 2, Assessment: 3 months immersion, no treatment: 2,
etter vannvasking: 8 after water washing: 8
12 måneders neddypping, ingen behandling; 4, 12 months immersion, no treatment; 4,
etter vannvasking: 4 after water washing: 4
Det fremgår av ovenstående tydelig at ytelsen av de to kjente midler som antibegroingsbelegg på en marinkonstruk-sjon er dårligere enn for belegg påført av slike blandinger som anvendes i henhold til foreliggende oppfinnelse. It is clear from the above that the performance of the two known agents as an anti-fouling coating on a marine construction is worse than for coatings applied by such mixtures as are used in accordance with the present invention.
Spesielt etter 12 måneders neddypping kan den betydelige begroing ikke fjernes ved vannvasking, slik belegg som anvendes i overensstemmelse med foreliggende oppfinnelse, Especially after 12 months of immersion, the significant fouling cannot be removed by water washing, such coatings as are used in accordance with the present invention,
kan det. can it.
