Vynález sa týká zmesi na protíkoróznu o-chranu kovových výrobkov, zvlášť výrobkovocelových v kombinácii s gumou.BACKGROUND OF THE INVENTION The present invention relates to a composition for corrosion protection of metal products, in particular steel products in combination with rubber.
Prostriedky dočasnej protikoróznej ochra-ny, ktoré sa nanášajú na kovový povrch zaúčelom zachovania užitkových vlastností vý-robkov, sú tvořené v prevažnej miere zme-sami koróznych inhibítorov v nevodnýchprostrediach, najmá v olejoch, vazelínách,v rozpúšťadlách typu benzínu, petroleja ale-bo v chlórovaných uhlovodíkoch. V prípadoch, keď výrobky sú vyrobenétak, že časť výrobku je z kovu a časť z kau-čukové j zmesi, najmá z gumy neodolnej vo-či olejom a rozpúšťadlám, olejové a rozpúš-ťadlové protikorózne prostriedky sa nemů-žu použiť, pretože by došlo k poškodeniuvýrobku. Ďalšia skupina protikoróznych prí-pravkov — papiere s vyparovacími inhibí-tormi korózie sa dajú použiť len s malýmefektom, a to najmá vtedy, ak sa na kovo-vom povrchu nachádzajú stopy neutrálnychelektrolytov, ktorých odstránenie by si vy-žiadalo zvýšené požiadavky na prácu, suro-viny a energie.Means of temporary corrosion protection applied to the metal surface in order to preserve the performance of the products are largely due to corrosion inhibitors in non-aqueous environments, in particular in oils, petrolatum, solvent-type gasoline, kerosene and petroleum solvents. chlorinated hydrocarbons. In cases where the articles are made such that a portion of the article is made of metal and a portion of the rubber composition, in particular non-oil- and solvent-resistant rubber, oil and solvent anticorrosive agents cannot be used because product damage. Another group of anticorrosion agents - papers with evaporative corrosion inhibitors can only be used with a small effect, especially when there are traces of neutral electrolytes on the metal surface, the removal of which would require increased work requirements, raw material. -viny and energy.
Uvedené nedostatky rieši zmes na pro- tikoróznu ochranu kovových výrobkov, zvlášť výrobkov ocelových v kombinácii s gumou podlá vynálezu, ktorej podstata spo- čívá v tom, že pozostáva z 0,5 až 70 % hmot- 2 nostných zmesi alkoholu, najmá glycerínua/alebo polyetylénglykolu s výhodou poly-etylénglykolu o strednej molekeulovej hmot-nosti 300 až 6000 a/alebo propylénglykolus výhodou mono-, di- a tripropylénglykolu,z 0,05 až 18 % hmotnostných zmesi dusita-nu alkalických kovov, najmá dusitanu sod-ného a hexametyléntetramínu alebo močo-viny, pričom hmotnostný poměr dusitanu ahexametyléntetramínu alebo močoviny, pri-čom hmotnostný poměr dusitanu a he-xametyléntetramínu alebo močoviny jes výhodou 0,05 : 1 až 1: 0,05, alebo z 0,05 až28 % hmotnostných zmesi dusitanu alka-lických kovov, najmá dusitanu sodného,etanolamínu, s výhodou monoetanolamínu,pričom hmotnostný poměr zložiek odpove-dá s výhodou poměru molekulových hmot-ností, alebo z 0,05 až 28 % hmotnostnýchzmesi benztriazolu a etanolamínu, s výhodoumonoetanolamínu, pričom poměr mólovbenztriazolu a etanolamínu je 1:1 až 1,3 :1,z 0,09 až 8 % hmotnostných benzoanu sod-ného a/alebo uhličitanu sodného, z 0,005až 1 % tenzidu neionogenného a/aleboanionaktívneho a zvyšok do 100 °/o tvořívoda.The above drawbacks are solved by a mixture of anticorrosive protection of metallic products, in particular steel products in combination with a rubber according to the invention, which consists of 0.5 to 70% by weight alcohol blends, in particular glycerol and / or polyethylene glycol preferably of ethylene glycol having a mean molecular weight of 300 to 6000 and / or propylene glycol preferably of mono-, di- and tripropylene glycol, of 0.05 to 18% by weight of a mixture of alkali metal nitrite, in particular sodium nitrite and hexamethylenetetramine or urea, wherein the ratio by weight of hexamethylenetetramine or urea nitrite, the weight ratio of nitrite and hexamethylenetetramine or urea is preferably 0.05: 1 to 1: 0.05, or from 0.05 to 28% by weight of alka nitrite mixture metals, in particular sodium nitrite, ethanolamine, preferably monoethanolamine, wherein the weight ratio of the components is preferably a molecular weight ratio; or from 0.05 to 28% by weight of a mixture of benztriazole and ethanolamine, preferably monoethanolamine, wherein the ratio of molybenzothiazole to ethanolamine is 1: 1 to 1.3: 1, from 0.09 to 8% by weight of sodium benzoate and / or sodium carbonate, from 0.005 to 1% nonionic surfactant and / or anionic surfactant;
Zmes podl'a vynálezu je možné na povrch výrobkov aplikovť najmá ponorom a postre- kom, připadne je možné výrobky baliť do 220285The composition according to the invention can be applied to the surface of the articles by immersion and spraying.
