KAUČUKOVĚJ FÓLIE NA OCEÍOKORDYRUBBER FOILS FOR OCEIOCORDS
Vynález sa týká spósobu kontinuálnej přípravy a pokladania kaučukovéj fólie na oceTokordy, ktorý efektívne uplatňuje výrobu kaučukových fólií a ich vtláčením za studená na oceTokordy.The present invention relates to a process for the continuous preparation and laying of a rubber foil for steel cords, which effectively applies the production of rubber foils and their cold pressing onto the steel cords.
V súčasnej době sú známe tri spósoby pokladania kaučukovéj fólie na oceTokord. Pri pokládání takzvaným iteplým spósobom využívá ea Tahšia tvarovateTnosť kaučukových fólií za tepla. Nevýhodou uvedeného spósobu je, že rozdielnym pnutím použitých konštrukčných materiálov, a to oceTokordu a kaučukovéj fólie, ako ja róznorodými pevnostami týchto materiálov, dochádza najmá u pneumatik za podmienok použitia k zvýrazneniu týchto rozdielov a v dósledku toho k defektem, připadne k zníženiu životnosti. U ďalšieho známého spósobu takzvaného studeného spósobu vtláčajú sa kaučukové fólie na oceTokordy za teplotnýeh podmienok blízkých teplotným podmienfcsm pri užívaní. Nevýhodou tohoto spósobu je, že sa zvyšujú manipulačně nároky pri výrobě, keď osobitné z východiskovej zmesi sa pripravujú kaučukové fólie a až po preprave svitkov a ich zaradení na funkčně miesta příslušného zariadenia dochádza k ich vtláčaniu do oeeTokordov. U tretieho spósobu takzvaného polostudeného, ktorý je svojim převedením v určitej miere kombináciou predehádzajúcich dvoch spósobov, kde sa jedna kaučukové folia privádza na oceTokordy studená a druhé sa móže pripraviť buď priamo z východiskovej zmesi za tepla a ešte teplá privádzať na oceTokordy, alebo sa ochladí na příslušná teplotu a ako ochladená sa vtláča na oceTokordy. Uvedený spósob má nevýhody v tom, že sa zvyšujú ma196811 nipulačné nároky pri výrobě a dochádza k nerovnoměrnému pnutiu pokaučukovaného oceTokordu.At present, three methods of laying rubber foil onto a steel cord are known. When used in a so-called warm manner, ea utilizes hot foil formability. The disadvantage of this method is that, due to the different stresses of the construction materials used, namely the cord and the rubber foil, as well as the different strengths of these materials, the tires under the conditions of use, in particular, accentuate these differences and consequently defects and reduce service life. In another known method of the so-called cold process, rubber foils are pressed onto the steel cords under temperature conditions close to those in use. The disadvantage of this method is that the manufacturing demands are increased when rubber foils are prepared separately from the initial mixture and are pressed into the oeeTocords only after the coils have been transported and placed in functionally the respective equipment. In the third method of the so-called semi-cold, which by its conversion is to some extent a combination of the previous two methods, where one rubber foil is fed to the steel cords cold and the other can be prepared either directly from the starting mixture hot and the appropriate temperature and how cooled it is pressed onto the steel cords. This method has the disadvantages that the manufacturing demands increase and uneven stresses of the rubberized steel cord occur.
Nevýhodou uvádzaných spósobov okrem už spomínaných nevýhod je, že každý rieši problematiku pokaučukovávania oceTokordov len čiastočne, pričom například z hTadiaka účinku adhéznych vlastností a podobné sa javí optimálnym studený spósob, kým z hladiska rozpracovanosti a' obdobných aspektov je priaznivejší teplý· spósob výroby, hoci je priestorove náročnější.The disadvantages of the above-mentioned methods, besides the above-mentioned disadvantages, are that everyone only partially solves the problem of scratching of the cords, and for example, from the point of view of adhesion properties and the like, the cold method appears optimal. spatially demanding.
Uvedené nedostatky odstraňuje spósob kontinuélnej přípravy a pokladania kaučukovéj fólie na oceTokordy podTa vynálezu, ktorého podstatou je, že kaučukové fólie připravené z východiskovej zmesi za tepla sa před pokládáním na ocel’okord odvédzajú z vyhrievapích valcov na sústavu chladiacich valcov, kde aa ochladia na teplotu 25 °C + 5 °C. Po vychladení sa kaučukové fólie cez navádzacie válce nanášajú na najmenej dva oceTokordy, smerujúce medzi vyhrievané přítlačné válce.The above-mentioned drawbacks are eliminated by the method of continuous preparation and laying of rubber foil for steel cords according to the invention, which is based on the fact that the rubber foils prepared from the hot starting material are removed from the heating rollers to the cooling rollers where they are cooled to 25 ° C. 5 ° C. After cooling, the rubber foils are applied to the at least two steel cords directed between the heated pressure rollers via the guide rolls.
Postup podTa vynálezu spája súčasnú výrobu kaučukových fólií z východiskových surovinových zmesi za tepla a vtlačením týchto fólií na oceTokordy po temperovaní na pracovnú teplotu blízku teplote okolia, takže vtláčanie na oceTokordy sa uskutočňuje analogicky s postupom pokaučukovania za studená. Úprava teploty fólie na technologická teplotu vtláčania sa uskutočňuje buď plynulým chladením, alebo ochladzovaním skokmi, a to v závislosti na použitom technologickom zariadení. Počet oceTokordov, na ktoré sa kaučuková fólie vtléčajú, je rfizny v závislosti na finálnom výrobku, ktorým je v uvedenom případe autoplášť.The process of the invention combines the simultaneous hot production of the rubber foils from the feedstock blends and presses the foils onto the steel cords after tempering to a working temperature close to ambient temperature, so that the injection on the steel cords is performed analogously to the cold blasting procedure. Adjustment of the film temperature to the injection molding temperature is carried out either by continuous cooling or by step cooling, depending on the technological equipment used. The number of octo-cords onto which the rubber foil is drawn is detailed depending on the final product, which in this case is a car tire.
Výhoda postupu podTa vynálezu spočívá v tom, že celý proces studeného pokaučukovania, ktorý dává požadované kvalitativně parametre pri výrobě kostry oceTokordových pneumatik s pokaučukovaných oceTokordov, možno kontinualizovať. Postup taktiež eliminuje podstatné namáhavú fyzickú précu, najmá vynecháním medzivýroby, znížuje straty pri náběhu a dobehu, ktoré sa vyskytovali pri doterajších spósoboch pokaučukovania za studená. Taktiež příprava kaučukovej fólie, jej odvádzanie, chladenie i navádzanie na oceTokordy sa prevádza na tom istom zariadení, ktoré je popisované v súvislosti so samotnou přihláškou vynálezu. Týmto spdaobom sa docieTuje vysoká pruduktívnosť pri požadovanej kvalitě pokaučukovaného oceTorekordu.The advantage of the process according to the invention is that the entire cold-rubbing process, which gives the desired qualitative parameters in the manufacture of the carcass of steel cord with rubbered steel cord, can be continualized. The process also eliminates substantial laborious physical work, notably bypassing intermediate production, reducing the incoming and decelerating losses that have occurred in the prior art cold blasting processes. Likewise, the preparation of the rubber foil, its removal, cooling and the guidance of the steel cords are carried out on the same apparatus as described in connection with the application itself. In this way, high conductivity is achieved with the desired quality of the rubberized steel recorder.
PříkladExample
Pře výrobu nákladných autoplášťov s oceTovou kostrou sa kontinuálně připravuje pokladacia kaučuková folia. Východisková zmes sa ohrieva na teplotu 80 °C + 10 °C a po stvárneni sa ochladzuje na teplotu 25 °C + 5 °C. Takto připravená kaučuková fólia sa na tom istom zariadení priamo vedie z vrchnej aj spodnej strany na súatavu oceTokordov kontinuálně odvíjaných cievočníc. Kaučuková folie sa plynule vtléčajú na sústavu privádzaných oceTokordov pri teplote pracoviska. Takto vyrobené pokaučukované oceTokordy sa používajú pri výrobě surového autoplášťa pre nárazníky a kostry.For the production of costly carcasses with a steel skeleton, a rubber foil foil is prepared continuously. The starting mixture is heated to 80 ° C + 10 ° C and cooled to 25 ° C + 5 ° C after formation. The rubber foil thus prepared is routed directly from the top and bottom side to the set of steel cords of the continuously unwound creeps on the same device. The rubber foils are continuously pushed onto the set of fed steel cords at the workplace temperature. The rubberized steels so produced are used in the production of a raw tire for buffers and carcasses.
