Description
Foreliggende oppfinnelse angår en begroingshindrende maling inneholdende et første og et andre vannløselig, sammensatt glassmateriale, hvor det første sammensatte glassmaterial et inneholder et begroingshindrende middel som frigjøres når glasset oppløses, idet oppiøseligheten for dette første gl assmaterial et bestemmes av pH-verdien til det omgivende vannet. The present invention relates to an anti-fouling paint containing a first and a second water-soluble composite glass material, where the first composite glass material contains an anti-fouling agent that is released when the glass dissolves, the solubility of this first glass material being determined by the pH value of the surrounding water .
I britisk patent nr. 1.511.381, offentliggjort etter foreliggende søknads prioritetsdato, er det beskrevet en begroingshindrende maling for bruk i marint- eller ferskvann-miljø, omfattende et pulverisert, glassaktig materiale dispergert i et harpiks-bindemiddel, hvor det glassaktige materialet omfatter et glassdannende oksyd, oksyder av ett eller flere metaller som er giftige for livet i hav eller ferskvann, samt ett eller flere glassmodifiserende oksyd(er) for å styre hastigheten ved hvilken det eller de giftige metaller frigjøres fra det glassaktige materialet for å gå over i en vandig løsning. In British patent no. 1,511,381, published after the priority date of the present application, an antifouling paint for use in a marine or fresh water environment is described, comprising a powdered, vitreous material dispersed in a resin binder, where the vitreous material comprises a glass-forming oxide, oxides of one or more metals that are toxic to marine or freshwater life, as well as one or more glass-modifying oxide(s) to control the rate at which the toxic metal(s) are released from the glassy material to transform into a aqueous solution.
Ved flere anvendelser er det ønskelig at hastigheten ved hvilken det giftige materialet frigjøres, varierer i overensstemmelse med forholdene ved beleggets overflate. Således er begroingen på et skip som ligger i ro eller beveger seg langsomt, betraktelig større enn på et skip som går for full fart. Hvis begroing skal hindres, er det derfor størst behov for frigjøring av giftige materialer når skipet ligger rolig. Ved alle begroingshindrende belegg som hittil har vært i bruk, har imidlertid det motsatte vært tilfelle. Dette har resultert i en uøkonom-isk bruk av beskyttelsesbelegget som altså i stor grad er blitt vasket bort mens skipet likevel hadde så stor fart at gifteffekten ikke var påkrevet. Dette fører også til en større belastning for det marine miljø, idet unødvendig store giftmengder løses opp i vannet mens skipet er i fart. In several applications, it is desirable that the rate at which the toxic material is released varies in accordance with the conditions at the surface of the coating. Thus, the fouling on a ship that is at rest or moving slowly is considerably greater than on a ship that is going at full speed. If fouling is to be prevented, there is therefore the greatest need for the release of toxic materials when the ship is at rest. However, the opposite has been the case with all anti-fouling coatings that have been in use to date. This has resulted in an uneconomical use of the protective coating, which has therefore largely been washed away, while the ship nevertheless had such a high speed that the poison effect was not required. This also leads to a greater burden on the marine environment, as unnecessarily large amounts of poison are dissolved in the water while the ship is in motion.
Formålet med foreliggende oppfinnelse er å tilveiebringe et beskyttelsesbelegg hvor hastigheten, hvormed beskyttelsesbeleggets aktive stoffer frigjøres, kan påvirkes på ønsket måte av forholdene ved beleggets overf1ate. The purpose of the present invention is to provide a protective coating where the speed with which the protective coating's active substances are released can be influenced in the desired way by the conditions at the surface of the coating.
Et ytterligere formål er å tilveiebringe en begroingshindrende maling som inneholder et begroingshindrende middel som oppløses i det omgivende vann, og hvor det begroingshindrende middel blir hurtigere frigjort jo langsommere den relative bevegelse mellom vann og belegg er. A further object is to provide an anti-fouling paint which contains an anti-fouling agent which dissolves in the surrounding water, and where the anti-fouling agent is released faster the slower the relative movement between water and coating is.
De viktigste særtrekk ved oppfinnelsen fremgår av de nedenfor fremsatte krav. The most important distinctive features of the invention appear from the claims set out below.
Sammensetningen er dispergert i et harpiks-bindemiddel slik at det fås en begroingshindrende maling f.eks. for bruk i marine omgivelser. Således kan det, ved å ta i bruk to ulike typer av aktive, utvalgte glassaktige materialer som hvert er jevnt fordelt i harpiks-bindemid-let, bli mulig å invertere den normale oppførsel for det biologisk aktive stoff i systemet slik at det frigjøres hurtigst i stillestående vann. Dersom f.eks. glass-materialet påføres skroget til et skip, kan glass-sammensetningen justeres slik at ved hastigheter som overstiger 5 knop og ved hvilke begroingen er neglisjerbar, blir frigjøringshastigheten for det biologisk aktive materialet fra glasset betraktelig mindre enn når skipet ligger stasjonært i forhold til vannet. The composition is dispersed in a resin binder so that an anti-fouling paint is obtained, e.g. for use in marine environments. Thus, by using two different types of active, selected vitreous materials, each of which is evenly distributed in the resin-binder, it may be possible to invert the normal behavior of the biologically active substance in the system so that it is released most quickly in stagnant water. If e.g. the glass material is applied to the hull of a ship, the glass composition can be adjusted so that at speeds exceeding 5 knots and at which fouling is negligible, the rate of release of the biologically active material from the glass is considerably less than when the ship is stationary in relation to the water.
I en utførelse av oppfinnelsen fremstilles belegget eller malingen av et bærestoff som inneholder to typer av In one embodiment of the invention, the coating or paint is produced from a carrier material that contains two types of
spesielt utvalgte glass-sorter A og B som er jevnt fordelt i harpiksen. Materialet A inneholder det biologisk aktive stoffet som har en frigjøringshastighet som er proporsjonal med konsentrasjonen av et 1ekkasjeprodukt fra materialet B i mediet som står i kontakt med overflaten til materialet A. Ved en foretrukken utførelse vil 1ekkasjeproduktet fra materialet B, når det er tilstede i tilstrekkelig konsentrasjon i vannet ved glassoverf1 aten A, opprettholde pH-verdien til vannet på et nivå ved hvilken glasset A vil løses langsomt opp, mens glasset A er praktisk talt uløselig i et nøytralt vandig medium, dvs. med pH-verdi lik 7. Derved kan det biologisk aktive materialet i glasset A bare oppløses i vannet ved tilstander som sikrer at materialet B ikke vaskes bort fra glassoverf1 aten. specially selected glass types A and B which are evenly distributed in the resin. The material A contains the biologically active substance which has a release rate that is proportional to the concentration of a breakdown product from the material B in the medium in contact with the surface of the material A. In a preferred embodiment, the breakdown product from the material B, when present in sufficient concentration in the water at the glass surface A, maintain the pH value of the water at a level at which the glass A will dissolve slowly, while the glass A is practically insoluble in a neutral aqueous medium, i.e. with a pH value equal to 7. the biologically active material in the glass A only dissolves in the water under conditions which ensure that the material B is not washed away from the glass surface.
I en anvendelse kan det biologisk aktive materialet A være et kobberborat-glass som bare er løselig i sure oppløsninger. Lekkasjehastigheten for dette materialet er i virkeligheten en eksponentiaT-funksjcn av pH-verdien til det omgivende, vandige medium. Materialet B kan da være et natrium-kalsium-fosfatglass med et høyt innhold av fosfor-pentoksyd og som frembringer en høy konsentrasjon av In one application, the biologically active material A may be a copper borate glass which is only soluble in acidic solutions. The leakage rate of this material is actually an exponential function of the pH of the surrounding aqueous medium. The material B can then be a sodium-calcium-phosphate glass with a high content of phosphorus pentoxide and which produces a high concentration of
. hydrogenioner når det lekker ut fra glasset. . hydrogen ions when it leaks from the glass.
En begroingshindrende maling i henhold til foreliggende oppfinnelse er naturligvis ikke begrenset til bruk på skip. Vanntanker, rørledninger, oljeboringsplattformer og sjøkabler kan også beskyttes på samme måte. An anti-fouling paint according to the present invention is of course not limited to use on ships. Water tanks, pipelines, oil drilling platforms and submarine cables can also be protected in the same way.
I andre utførelser kan kontrollmaterialet for styring av frigjøringshastigheten være et gelateringsmiddel for en kation av glasset som inneholder det aktive materialet og kan derved bedre dets løselighet. In other embodiments, the control material for controlling the release rate may be a gelling agent for a cation of the glass containing the active material and may thereby improve its solubility.
