Description
Påstrykningsmiddel for metaller. Coating agent for metals.
Det er kjent å anvende metalloksyder It is known to use metal oxides
som passiverende middel i påstrykningsmidler, særlig i slike som tjener til over-trekning av metaller. Videre er det kjent å innforlive forskjellige metalloksyder, f. eks. av metalloksyder bestående pigmenter, sammen med organiske baser i mot rust beskyttende påstrykningsmidler. as a passivating agent in coating agents, particularly in those that serve to coat metals. Furthermore, it is known to incorporate various metal oxides, e.g. pigments consisting of metal oxides, together with organic bases in anti-rust coating agents.
Oppfinnerne har funnet, at påstrykningsmidler gir en særlig god beskyttelse mot rust når de inneholder kobberoksyd eller dettes hydrat sammen med tertiære heterocykliske baser. Særlig virksomme er slike påstrykningsmidler når deres bindemiddel bare eller for den vesentligste del består av klorholdige organiske polymere, særlig av klorkautsjuk. The inventors have found that coating agents provide particularly good protection against rust when they contain copper oxide or its hydrate together with tertiary heterocyclic bases. Such coating agents are particularly effective when their binder consists only or for the most part of chlorine-containing organic polymers, in particular of chlorinated rubber.
Som tertiære heterocykliske baser As tertiary heterocyclic bases
kommer ved siden de tekniske pyridinbase-blandinger på tale slike som f. eks. pyridin, kinolin, pikolin eller substitusjonsproduk-ter av disse. Den passiverende beskyttende virkning av påstrykningsmidler i henhold til oppfinnelsen viser seg meget tydelig ved at under innflytelse av de i påstryk-ningsmidlene inneholdte blandinger av next to the technical pyridine base mixtures in question such as e.g. pyridine, quinoline, picoline or substitution products thereof. The passivating protective effect of coating agents according to the invention is shown very clearly by the fact that under the influence of the mixtures of
metalloksyder eller disses hydrater og heterocykliske baser opphører etter kort tids forløp den vannstoffutvikling som begyn-ner straks etter at påstrykningsfilmer på uedle metaller der er i berøring med syre er blitt beskadiget, og syreangrep, som be-gynner på det frilagte sted av metallet, opphører. metal oxides or their hydrates and heterocyclic bases cease after a short period of time the hydrogen evolution that begins immediately after coating films on base metals in contact with acid has been damaged, and acid attack, which begins at the exposed location of the metal, ceases .
Med fordel inneholder påstrykningsmidler i henhold til oppfinnelsen 0,5—15 deler kobberoksyd eller dettes hydrat pr. 100 deler bindemiddel, og likeledes med fordel 0,5—15 deler av en tertiær, heterocyklisk base pr. 100 deler bindemiddel. Advantageously, coating agents according to the invention contain 0.5-15 parts of copper oxide or its hydrate per 100 parts binder, and likewise advantageously 0.5-15 parts of a tertiary, heterocyclic base per 100 parts binder.
Videre kan påstrykningsmidler i henhold til oppfinnelsen med fordel inneholde finfordelte oksyder av andre metaller eller av metalloider, særlig når påstryknings-midlene er tenkt anvendt som grundering for ytterligere overtrekk. Disse oksyder er fortrinsvis slike som er blitt fremstilt i finfordelt form ved termisk omsetning av flyktige forbindelser imed vanndamp eller surstoff i gassfase. Tilsetning av slike finfordelte oksyder av metaller eller metalloider, særlig av aluminiumoksyd, bevirker at de ytterligere overtrekk henger meget godt fast på grunderingen. Furthermore, coating agents according to the invention can advantageously contain finely divided oxides of other metals or of metalloids, particularly when the coating agents are intended to be used as a primer for additional coatings. These oxides are preferably those which have been produced in finely divided form by thermal reaction of volatile compounds with water vapor or oxygen in gas phase. Addition of such finely divided oxides of metals or metalloids, particularly of aluminum oxide, causes the additional coatings to adhere very well to the primer.
