Description
Oppfinnelsen vedrører et system for beskyttelse av skip mot begroning og korrosjon, omfattende et korrosjonsbeskyttende primersjikt og et begroningshindrende yttersjikt som inneholder kobberoksydul og/eller faste organometalliske giftstoffer, som f. eks. tributyltinnfluorid (TBTF), i samsvar med norsk patent nr. 136.645. The invention relates to a system for protecting ships against fouling and corrosion, comprising a corrosion-protective primer layer and a fouling-preventing outer layer containing copper oxide and/or solid organometallic toxins, such as e.g. tributyltin fluoride (TBTF), in accordance with Norwegian patent no. 136,645.
I det norske patent er det beskrevet et system som •er kjennetegnet ved at primeren er tilblandet :bis(tributyltinn)-oksyd (TBTO) -og/eller tributyltinnklorid (TBTC1) som myknings-•middel og som ytterligere, i og for seg kj.ent begroningshindrende-.middel, beregnet på å migrere gjennom yttersjiktet, samt et •fortykningsmiddél som i og for seg kjent.. TBTO og TBTC1 er begge flytende, oljeaktige stoffer..Begge virker som myknings-imidler i en malingsfilm, og som de fleste mykningsmidler migre-rer de opp til .overflaten .av en imalingsf ilm. The Norwegian patent describes a system characterized by the fact that the primer is mixed with: bis(tributyltin) oxide (TBTO) and/or tributyltin chloride (TBTC1) as a plasticizer and as an additional, in and of itself kj .ent anti-fouling-.agent, designed to migrate through the outer layer, as well as a •thickening agent known per se.. TBTO and TBTC1 are both liquid, oily substances..Both act as softeners in a paint film, and as they most plasticizers migrate up to the surface of a coating film.
Man "har .nu f unnet .at .bis ( tributyltinn) sulf id, i det følgende betegnet som TBTS, og fbis(tributyltinn)tetraklorftalat har tilsvarende egenskaper og virkninger som TBTO og TBTC1. De adskiller seg i det vesentlige ved sin mindre vannløselighet og langsommere migrering enn de to nevnte stoffer, samt ved at det ikke er nødvendig å ;benytte fortykningsmidler for å sikre en god adhesjon til .underlaget og motvirke en klebrig overflate på primersjiktet. It has now been discovered that bis (tributyltin) sulphide, hereinafter referred to as TBTS, and bis(tributyltin) tetrachlorophthalate have similar properties and effects as TBTO and TBTC1. They differ essentially by their lower water solubility and slower migration than the two substances mentioned, as well as the fact that it is not necessary to use thickeners to ensure good adhesion to the substrate and counteract a sticky surface on the primer layer.
Hensikten med foreliggende oppfinnelse er således å kunne oppnå en enda større variasjon i virkningsgraden og effek-tivitetstiden for systemet i henhold til norsk patent nr. 136.645. The purpose of the present invention is thus to be able to achieve an even greater variation in the degree of effectiveness and the effectiveness time for the system according to Norwegian patent no. 136,645.
Dette oppnås ved et system som er kjennetegnet ved det som fremgår av kravet. This is achieved by a system that is characterized by what appears in the requirement.
Ved en kombinasjon med TBTO og/eller TBTC1 kan det oppnås en enda lengre migreringstid, idet stoffene løses etter hverandre,' hvorved stoffet med kortest .migreringstid løses ut først. In a combination with TBTO and/or TBTC1, an even longer migration time can be achieved, as the substances are dissolved one after the other, whereby the substance with the shortest migration time is dissolved first.
I det følgende skal det angis eksempler på sammensetninger av primer i samsvar med oppfinnelsen, samt anti-foulingbelegg. In the following, examples of compositions of primers in accordance with the invention, as well as anti-fouling coatings, shall be given.
Primer Primer
1) Klorkautsjuk og klorerte parafiner -. 27,3 vektprosent Korrosjonshindrende pigmenter (Al-flak, I begge eksempler kan den angitte tinnforbindelse helt eller delvis erstattes med en eller flere av de andre i kravet nevnte forbindelser. 1) Chlorinated rubber and chlorinated paraffins -. 27.3 percent by weight Corrosion-inhibiting pigments (Al flakes, In both examples the specified tin compound can be replaced in whole or in part with one or more of the other compounds mentioned in the claim.
Disse primere og anti-foulingbelegg kan brukes i alle kombinasjoner. Primersjiktet bør ha en tykkelse mellom 50 og 8 0 pm. Også andre sammensetninger er mulige. Ved kombinasjon med TBTO og/eller TBTC1 kan det oppnås en ytterligere forlengelse av beskyttelsestiden. These primers and anti-fouling coatings can be used in any combination. The primer layer should have a thickness between 50 and 80 pm. Other compositions are also possible. In combination with TBTO and/or TBTC1, a further extension of the protection time can be achieved.
