Description

Przedmiotem wynalazku jest gietki korpus war¬ stwowy, zwlaszcza tasma przenosnikowa lub pas napedowy wytwarzany z gumy lub gumopodob- nych tworzyw elastomerycznych i zawierajacy me¬ talowe wkladki wzmacniajace w postaci osadzo¬ nych wzdluznie w poblizu lin stalowych, badz splotkowych i tym podobnych materialów.Ochrona metalowych wkladek wzmacniajacych, umieszczonych w wyrobach gumowych i z two¬ rzywa sztucznego znajdujacych rózne zastosowanie w technice, przed dzialaniem korozji, wywolanej czynnikami atmosferycznymi stanowi ciagle pro¬ blem, którego nie udaje sie rozwiazac w sposób zadawalajacy, mimo dalekosieznych nakladów w konkretnych przypadkach. Calkowita ochrona ota¬ czajacego tworzywa elastomerycznego jest w prak¬ tyce niemozliwa.Na duze trudnosci napotyka sie juz w uzyskaniu calkowitego szczelnego oblozenia wkladek przyle¬ gajacym do nich na calej powierzchni tworzywem elastomerycznym, poza tym kolejna niedogodnoscia sa mechaniczne uszkodzenia naniesionej warstwy wierzchniej, wywolane dynamicznym obciazeniem przedmiotów, ulatwiajace przenikanie w glab wil¬ goci. Z tego wzgledu ubytki spowodowane korozja nie powstaja w jednym miejscu, lecz postepuja wzdluz wkladek na duzych odcinkach, w zalez¬ nosci od struktury materialu wkladek, tak ze po¬ czatkowo niezauwazalne zmiany korozyjne prowa¬ dza do duzych uszkodzen. 10 16 20 25 30 Szczególnie zagrozone sa tasmy przenosnikowe z osadzonymi w podlozu linami stalowymi lub splotkowymi jako tasmy z nosnikami wytrzyma¬ losciowymi, obciazonymi silami wzdluznymi. Sto¬ sunkowo luzna struktura liny, uwarunkowana jej budowa, skladajaca sie z duzej liczby pojedyn¬ czych drutów, o nieciaglej powierzchni i posiada¬ jaca przenikajace az do rdzenia puste przestrze¬ nie, uniemozliwia — przy stosowaniu znanych technik — pozadane, calkowicie szczelne obloze¬ nie jej przyczepnym srodkiem, wiazacym ja z tworzywem elastomerycznym, przede wszystkim w przypadkach duzych srednic tych lin.Przeprowadza sie wiele prób w celu uzyskania dokladnego „przewiazania" wkladek guma lub tworzywem sztucznym, przykladowo na drodze im¬ pregnowania lin drucianych roztworem gumy, ota¬ czania pojedynczych drutów lub lin bardziej pla¬ styczna mieszanina, przez dodawanie plastycznych skladników juz na etapie wykonywania lin, itp.Wszelkie starania w tym kierunku dawaly jedy¬ nie czesciowe efekty.Celem wynalazku jest zapewnienie skutecznej i ciaglej ochrony metalowych wkladek w obciaza¬ nych dynamicznie przedmiotach z gumy lub z two¬ rzywa sztucznego, przy zachowaniu ich nierozlacz¬ nego polaczenia bezposredniego z tworzywem pod¬ loza, przed dzialaniem korodujacym zewnetrznych wplywów atmosferycznych, zwlaszcza przed prze¬ nikaniem wilgoci. Ma to szczególne znaczenie w 119 975119 3 przypadku stosowania tzw. tasm przenosnikowych z lin stalowych i pasów przenoszacych sily, skla¬ dajacych sie z osadzonych wzdluznie lin drucia¬ nych lub podobnych pasmowych metalowych nos¬ ników wytrzymalosciowych. Wynalazek nie ma jednak tak ograniczonego zakresu zastosowania, lecz moze byc wykorzystany w szerokim zakresie do innych, stosowanych w technice gietkich kor¬ pusów warstwowych.Cel ten osiagnieto dzieki temu, ze metalowe wkladki, polaczone nierozlacznie przynajmniej cze¬ scia swojej powierzchni z otaczajacym tworzywem elastomerycznym, maja powloke wytworzona z plynnego srodka antykorozyjnego, sporzadzonego na bazie skladnika mieszaniny tworzyw elastome- rycznych do powszechnego stosowania lub szcze¬ gólnej mieszaniny, stosowanej do kazdorazowo da¬ nego korpusu warstwowego, korzystnie na bazie pomocniczego srodka przetwórczego i/lub zmiek- czacza. W zaleznosci od rodzaju i struktury two¬ rzywa podloza, srodek antykorozyjny moze byc sporzadzony np. na bazie parafinowych lub nafte-, nowych olejów mineralnych, chloroparafin lub cie¬ klego, organicznego zwiazku estrowego lub etero¬ wego. W kazdym przypadku baza srodka ochron¬ nego powinna byc tak dobrana, aby srodek ten zawieral w efekcie koncowym skladniki hydrofo¬ bowe (nawilzalne woda).Plynne srodki antykorozyjne do powierzchnio¬ wego traktowania wolno rozpietych lub stosowa¬ nych w innym ukladzie lin pociagowych sa znane.Jednakze dostepne w handlu srodki ochronne, sporzadzane zasadniczo na bazie olejów, wosku czy wazeliny, nie byly w przypadku gietkich kor¬ pusów warstwowych brane pod uwage, poniewaz nalezalo liczyc sie z powaznym obnizeniem ich przyczepnosci do powierzchni.Rozwiazanie wedlug wynalazku polegajace na wstepnym traktowaniu elementów wkladki, daje w wyniku nieoczekiwanie korzystne efekty, obja¬ wiajace sie znacznie mniejsza podatnoscia na ko¬ rozje, a jednoczesnie lepsza odpornoscia wkladki na obciazenia dynamiczne, oraz zwiekszona odpor¬ noscia na wysokie obciazenia zmienno-gnace, np. w przypadku tasmy przenosnikowej z lin stalo¬ wych podczas próby zmeczeniowej. Spowodowane jest to prawdopodobnie dodaniem sie wielu istot¬ nych poszczególnych efektów. Po pierwsze mie¬ szanina tworzyw: elastomerycznych w fazie plyn¬ nej przed zastygnieciem moze przenikac w prze¬ strzenie miedzy pojedynczymi drutami. Po drugie, najmniejsze puste przestrzenie miedzy poszczegól¬ nymi drutami wypelniaja sie srodkiem hydrofobo¬ wym, który jednoczesnie jako smar przeciwdziala bezposredniemu, metalicznemu tarciu slizgowemu wewnatrz lin, a w koncu zamknieta powloka, ota¬ czajaca liny bez wzgledu na strukture ich po¬ wierzchni, stanowi doskonala ochrone przed prze¬ nikaniem wilgoci do tworzywa podloza przez po¬ wstale zarysowania lub inne miejsca uszkodzen.Dodatkowa zaleta jest dzialanie ochronne srod¬ ka antykorozyjnego przed przerabianiem elemen¬ tów wkladki.Drukarnia Narodi 975 4 Wynalazek opiera sie na dobrym wspóldzialaniu srodka antykorozyjnego ze skladem mieszanin two¬ rzyw elastomerycznych, w wyniku którego sro¬ dek ten jest przyjmowany przez mieszaniny w 5 przewidywanych miejscach wiazania.Przedmiot wynalazku jest przedstawiony w przy¬ kladzie wykonania na rysunku, na którym uwi¬ doczniono tasme przenosnikowa z linami stalo¬ wymi we fragmentarycznym przekroju poprzecz¬ ni nym.Uwidoczniona tasma przenosnikowa sklada sie z górnej i dolnej warstwy pokrywajacej 1 i 2 oraz osadzonej miedzy nimi i przebiegajacej z obustronnymi odstepami, równolegle w kierunku 15 wzdluznym warstwy rdzeniowej 3, zawierajacej liny druciane 4 jako nosnik wytrzymalosciowy.Obie warstwy pokrywajace 1, 2 wykonane sa ze wzgledu na duze obciazenia mechaniczne z odpor¬ nej na scieranie, ciagliwo-twardej mieszaniny kau- 20 czukowej, natomiaast wewnetrzna warstwa rdze¬ niowa 3 ma dobre nierozlaczne polaczenie z war¬ stwami pokrywajacymi 1 i 2 oraz z zatopionymi linami drucianymi 4.Liny druciane 4 sa powleczone srodkiem anty- 25 korozyjnym 5, zawierajacym olej na bazie naftenu.Zastrzezenia patentowe 1.

Protection metal reinforcing inserts placed in rubber and plastic products used in various technical applications against corrosion caused by atmospheric factors is still a problem that cannot be solved satisfactorily, despite extensive investments in specific cases. Complete protection of the surrounding elastomeric material is practically impossible. Great difficulties are encountered in achieving a completely tight covering of the inserts with the elastomeric material adhering to them over the entire surface, and another disadvantage is mechanical damage to the applied top layer caused by dynamic load on objects, facilitating the penetration of moisture into the interior. For this reason, corrosion damage does not occur in one place, but progresses along the inserts over large sections, depending on the structure of the insert material, so that initially imperceptible corrosion changes lead to large damages. 10 16 20 25 30 Conveyor belts with steel or strand ropes embedded in the ground as belts with strength carriers loaded with longitudinal forces are particularly at risk. The relatively loose structure of the rope, determined by its structure, consisting of a large number of individual wires, with a discontinuous surface and having empty spaces penetrating into the core, makes it impossible - when using known techniques - to obtain the desired, completely tight drapes. not its adhesive agent that binds it to the elastomeric material, especially in the case of large diameters of these ropes. Many attempts are made to obtain a precise "bonding" of the inserts with rubber or plastic, for example by impregnating wire ropes with a rubber solution connecting individual wires or ropes with a more plastic mixture, by adding plastic components already at the stage of making the ropes, etc. All efforts in this direction gave only partial results. The aim of the invention is to ensure effective and continuous protection of metal inserts under dynamic loads. rubber or plastic objects, while maintaining their inseparable direct connection with the base material, against the corrosive effects of external atmospheric influences, especially against the penetration of moisture. This is particularly important in the case of using the so-called conveyor belts of steel ropes and force-transmitting belts consisting of longitudinally mounted wire ropes or similar strips of metal strength carriers. However, the invention does not have such a limited scope of application, but can be used to a wide extent for other flexible laminate bodies used in the technique. This goal was achieved thanks to the fact that metal inserts, at least part of their surface, are inseparably connected with the surrounding elastomeric material. , have a coating made of a liquid anti-corrosion agent prepared on the basis of a component of a mixture of elastomeric materials for general use or a specific mixture applied to a given laminated body, preferably based on an auxiliary processing agent and/or plasticizer. Depending on the type and structure of the base material, the anti-corrosion agent may be prepared, for example, on the basis of paraffin or kerosene, new mineral oils, chloroparaffins or a liquid, organic ester or ether compound. In each case, the base of the protective agent should be selected in such a way that the agent ultimately contains hydrophobic components (water-wettable). Liquid anti-corrosion agents for the surface treatment of slowly unspanned ropes or used in another arrangement are known. However, commercially available protective agents, mainly based on oil, wax or Vaseline, were not taken into account in the case of flexible layered bodies, because their adhesion to the surface could be significantly reduced. The solution according to the invention consisted in pre-treatment elements of the insert, gives unexpectedly beneficial effects, manifested by a much lower susceptibility to corrosion, and at the same time better resistance of the insert to dynamic loads, and increased resistance to high variable-bending loads, e.g. in the case of a conveyor belt with steel ropes during the fatigue test. This is probably due to the addition of many important individual effects. Firstly, the mixture of elastomeric materials in the liquid phase may penetrate into the spaces between individual wires before solidifying. Secondly, the smallest empty spaces between individual wires are filled with a hydrophobic agent, which, at the same time as a lubricant, prevents direct metallic sliding friction inside the ropes, and finally, the closed coating surrounding the ropes regardless of their surface structure constitutes excellent protection against the penetration of moisture into the base material through scratches or other damaged places. An additional advantage is the protective effect of the anti-corrosion agent against alteration of the insert elements. Narodi Printing House 975 4 The invention is based on the good interaction of the anti-corrosion agent with the composition mixtures of elastomeric materials, as a result of which this agent is absorbed by the mixtures in 5 expected bonding places. The subject of the invention is presented in an exemplary embodiment in the drawing, which shows a conveyor belt with steel ropes in a fragmentary cross-section transversely. The conveyor belt shown consists of an upper and lower covering layer 1 and 2 and a core layer 3 embedded between them and running with spaces on both sides, parallel in the longitudinal direction, containing wire ropes 4 as a strength carrier. Both covering layers 1 , 2 are made of an abrasion-resistant, ductile-hard rubber mixture due to high mechanical loads, while the inner core layer 3 has a good, inseparable connection with the covering layers 1 and 2 and with the embedded wire ropes 4. The wire ropes 4 are coated with an anti-corrosion agent 5 containing a naphthene-based oil. Patent claims 1.
