Description

Przedmiotem wynalazku jest sposób wytwarza¬ nia folii laminowanej metoda ciagla, w którym wstege termotopliwej folii .polietylenowej o sto¬ sunkowo znacznej grubosci laczy sie ze wstega materialu wlóknistego majacego zdolna do lacze¬ nia powierzchnie np. zawierajaca zywice poliety¬ lenowa.Przedmiotem wynalaziku jest równiez urzadze¬ nie 'do wytwarzania folii laminowanej.Sipasoby laczenia materialów o powierzchniach z tworzyw sztucznych sa • znane. W oipiisie paten¬ towymi RFN nr 1779124 .opisano metode 'laminowa¬ nia iprzez laczenie ze soba dwóch folii, z których co najmniej jedna zaopatrzona jest w warstwe polimeru termoplastycznego. Folie przechodza mie¬ dzy dwoma ogrzewanymi walcami laczac sie pod ich naciskiem, przy czym jedna z folii przechodzi równiez przez ogrzewana laznie znajdujaca sie powyzej tych walców. Stosowano kapiel o tempe¬ raturze 8'0—100°C tzn. o takiej samej temperatu¬ rze jaka mialy walce. Celem dla którego jedna z folii prowadzono przez kapiel wodna bylo wlacza¬ nie malej ilosci wilgoci do laminatu, aby zapobiec jego wysuszaniu sie i lamliwosci. Sposób ten nie nadaje sie do laminowania folii polietylenowych, a zwlaszcza grubych folii z polietylenu o wysokiej gestosci, gdyz nie mozna ogrzac folii do wymaga¬ nej temperatury w krótkim czasie pozostawania w lazni lub pomiedzy walcami.W opisie patentowym RFN nr 1911425 dotycza¬ cym laminowania cienkich folii 'polietylenowych z zastosowaniem ciepla 1 cisnienia podano,, ze ci¬ snienie nalezy stosowac przez znaczny okres cza- 5 su, np. przez co najmniej 15 minut, co oznacza, ze sposólb nie moze 'byc wykorzystany w metodzie ciaglej, przy której czas wywierania cisnienia jest niezmiernie krótki. W opisie patentowym RFN nr 1161679 opisano sposób laczenia razem dwóch folii o róznych temperaturach topnienia. Folie 10 poddawane byly obróbce rozciagajacejm w celu zo¬ rientowania struktury krystalicznej w jednym lub dwóch kierunkach, po czym laczono je ze soba z zastosowaniem ciepla. Sposobu tego nie mozna by¬ lo wykorzystac, gdy folie byly ciagniete ze szpul. 15 W opisie patentowym Stanów Zjednoczonych Am. nr 3400972 opisano sposób laczenia dwóch folii bez uzycia spoiwa luib ogrzewania. Laminowa¬ nie folii osiagano przez kompletne wycisniecie •po¬ wietrza z powierzchni granicznych miedzy dwoma 20 foliami tak, aby uzyskac wiazanie molekularne.Sposób ten wymagal stosowania absolutnie ideal¬ nych powierzchni folii i nie mozna go bylo stoso¬ wac dla folii zwyklych a w zadnym przypadku dla folii stosunkowo grubych i sztywnych. 25 W opisie patentowym RFN nr 195&8&1 opisano sposób laczenia na goraco dwóch folii iprzez za¬ stosowanie dwóch zespolów ogrzewajacych na po¬ wierzchniach przesuwajacych sie folii. Grzejni¬ ków tego typu nie imoizna jednakze bylo istosowac j3 na przesuwajacej sie wstedze polioiefiny, zwlasz* 114 6063 114 606 4 cza na folii grubej,, poniewaz ilosc ciepla zaabsor¬ bowanego przez folie nie wystarczala do zlaczenia jednej folii z lepka powierzchnia drugiej folii,, zas jesli sie folii pcliolefiinowej dostarczylo dostate¬ czna ilosc ciepla alby folie mogly sie polaczyc, .to stawala sie ona talk slaiba, ze nastepowalo jej wiotczenie i zrywala sie.W opisie patentowym RFN nr 1,1133537 opisano urzadzenie, w którym ogrzewanie folii prowadzo¬ no przy uzyciu dwóch zespolów grzewczych bez¬ posrednio dzialajacych na powierzchnie folii. Je¬ dnakze efekt grzania toyl zibyt maly aby gruba fo¬ lia poliolefincwa polaczyla sie z folia o lepkiej powierzchni. Znane z opisu patentowego EiFN nr 1504154 urzadzenie do laczenia folii równiez wyposazone bylo w elementy grzewcze zainstalo¬ wane na drodze folii ze szpul do miejsca lacze¬ nia z druga folia.Jak wynika ze stanu techniki dla utworzenia laminatu, wstege cienkiej folii zywicy policlefino'- wej, takiej jak polietylen o wysokiej gestosci, mozna ibylo z powodzeniem polaczyc z ciensza wstega na iprzyklad materialu wlóknistego takie¬ go jak papier siarczanowy majacy powierzchnie pokryta zywica policletfincwa przez doprowadzenie tej powierzchni do .stanu 'kleistego luib stopione¬ go i zlaczenie ze soba materialów. Normalnie wstege ma-terialu wlóknistego spryskiwano do gru¬ bosci na przyklad 0,02 mm, warstewka tworzywa sztucznego topniejacego pod wjplywem cie¬ pla. Takie postepowanie bylo nai ogól zadawalajace, gdy temperatura wstegi folii odpo¬ wiadala temperaturze pokojowej lub byla niezna¬ cznie 'wyzsza* pod warunkiem, ze grulbosc wstegi folii (byla mniejsza od okolo 0,02 mm. Jesli gru¬ bosc wstegi folii byla wieksza od tej wartosci, wiazanie w pewnych obszarach laminatu Ibylo zlej jakosci, natomiast przy grubosci przekraczajacej okolo 0,07 imm wiazanie w ogóle nie nastepowalo.Problem wiazania jest szczególnie powazny, gdy stosuje sie tworzywo typu poliolefiny o wysokiej gestosci w odniesieniu do folii i ewentualnie rów¬ niez, w odniesieniu do powleczenia na wstedze wlóknistej. Polietylen o wysokiej gestosci wytwa¬ rzany przy stosunkowo niskich ¥ cisnieniach w obecnosci ikatalizatora, zawiera czastki o lancu¬ chach tylko z nielicznymi odgalezieniami boczny¬ mi. Polietylen o wysokiej gestosci jest 'stosunkowo sztywny i bardzo odporny, na (przyklad,, na oleje i rozpuszczalniki. Powoduje to, ze laminaty za¬ wierajace folie z polietylenu o wysokiej gestosci sa konsekwentnie stosowane w ogromnie wielu dziedzinach. Dotychczas nie mozna (bylo wykorzys¬ tac dobrych wlasnosci tego tworzywa ze wzgledu na trudnosci zwiazane z laczeniem sie wstegi folii wykonanej z takiego tworzywa sztucznego ze wistega wlóknista luib inna stosiunkowo gruba fo¬ lia, gdy laczenie ze soba olbu materialów wiinno byc przeprowadzone szybko, na iprzyklad przy szybkosci Gy5 m/s. Cisnienie potrzebne ido zlacze¬ nia dwóch folii normalnie wytwarzane jest przez ?nacisk walców a zatem przy walcach o bardzo du¬ zych srednicach, przeciag czasu przez który obie wstegi musialy byc w kontakcie z walcami, otyli czas wywierania nacisku jest bardzo króltki.Przyczyna, dla której wstega (polietylenu o wy- sokiej gestosci o grubosci przekraczajacej okolo 0,02 mm i temperaturze odpowiadajacej tempera¬ turze pokojowej nie jest zdolna do przywarcia do stopionej warstwy polietylenu lub warstwy dowol¬ nej innej poliolefiny, jak sie przypuszcza wynika z pewnej bezwladnosci czasteczki, która wyraza sie niezdolnoscia warstwy do topnienia dopóki nie przeminie ipewien okres czasu od zastosowania grzania warstwy oraz tym, ze czas reagowania zwieksza sie z gruboscia folii tworzywa sztuczne¬ go. 'Gdy folie o malej grubosci,, na przyklad 0,01 mm przyciska sie do stopionej warstwy wstegi wlóknistej o temperaturze, na przyklad 130°C cie¬ plo zostaje przekazane z powleczenia do folii two¬ rzywa sztucznego i ze wzgledu na mala grubosc- powoduje topnienie laminarne, w wyniku którego dwie wstegi wiaza sie ze soba w czasie wywiera¬ nia cisnienia. Jednakze, jezeli na stopione powle¬ czenie naklada sie gruba folie polietylenowa; któ¬ rej temperatura odpowiada temperaturze pokojo¬ wej, czas reagowania -czasteczek folii jest tak dlu¬ gi i ilosc potrzebnego ciepla. jest tak: duza, ze nie nastepuje topnienie w czasie wywierania cisnienia i w rezultacie nie jest mozliwe uzyskanie wiaza¬ nia.Problem wystepowania pewnej bezwladnosci czasteczek polietylenu, przy laczeniu ze soba dwóch powleczonych wsteg wlóknistych próbowa¬ no rozwiazac przez stapianie powleczen dwóch wsteg wlóknistych i nastepnie przyciskanie ich do siebie. Tecnnika] ta nie moze byc jednakze stoso¬ wana przy nakladaniu wstegi folii tworzywa sztu¬ cznego na powleczona wstege wlóknista, poniewaz grzanie wsteg tworzywa sztucznego, na przyklad plomieniem gazowym,, tuz przed strefa wiazania z materialem wlóknistym powoduje, ze folia z tworzywa sztucznego przypala sie lub mieknie w takim zakresie, ze nie mozna jej ciagnac z walca magazynowego. Mimo, ze grzanie plomieniem ga¬ zowym lub innym odpowiednim zródleim ciepla tuz przed strefa wiazania nie jest teoretycznie wy¬ kluczone, dlugi czas reagowania grubego poliety¬ lenu o wysokiej gestosci wymagal bedzie, dla uzyskania zwiazania dwóch materialów razem bardzo powolnego przesuwania wsteg, zas taki proces nie bedzie interesujacy z przemyslowego punktu widzenia.Celem wynalazku bylo opracowanie nowego i -uzytecznego sposobu laminowania stosiunkowo grubej wstegi folii majacej powierzchnie z (Dofli- olefiny. Sposób bazuje na technice, w której cza¬ steczki na dlugo przed polaczeniem ze soba ma¬ terialów zostaja jakby pobudzone luib uaktywnio¬ ne w sposób taki, ze beda natychmiast reagowaly na cieplo stosowane do topienia tworzyw sztucz¬ nych,- niezaleznie od grubosci folii.Wedlug wynalazku sposób wytwarzania folii la¬ minowanej metoda ciagla, w którym wstege top¬ niejacej pod wplywem ciepla folii polietylenowej pobierana z urzadzenia zasilajacego przez odwija- nie z zapasowej szpuli podgrzewa sie i laczy przez wywarcie cisnienia ze wstega zdolna do wiazania zawierajaca warstwe wlóknista papierowa i war¬ stwe poliolefiriowa, podgrzana do stanu kleistosci, 10 15 20 25 30 35 40 45 50 55 605 114 606 6 polega na tym, ze wstege poliolefinowa przed od¬ winieciem jej z zapasowej szpuli i odebraniem- z urzadzenia zasilajacego ogrzewa sie do temperatu¬ ry przejsciowej, 'nizszej od temperatury topnienia poliolefiny. Na oigól wstege z polietylenu niskocis- nieniowego ogrzewa sie do temperatury przejscio¬ wej odpowiadajacej 50^-05% temperatury topnie¬ nia poliolefiny.Urzadzenie do wytwarzania folii laminowanej metoda ciagla skladajace sie z mrizadzen zasilaja- cych z elementami do odwijania folii ze szpul, elementów do podgrzewania zdolnej do wiazania wstegi., elementów do prowadzenia folii oraz pary walców do sprasowania wstegi ipoliolefinowej ze wstega zdolna do wiazania, wedlug wynalazku ma przyporzadkowane urzadzeniu zasilajacemu urza¬ dzenie ogrzewajace folie przed odwinieciem jej ze szpuli.Wynalazek wyjasniono ponizej w nawiazaniu do zalaczonego schematycznego rysunku, którego po¬ jedyncza figura ilustruje przyklad wykonania urzadzenia do prowadzenia sposobu.Na figurze zilustrowano kabine lufo komore 17 grzewcza, której wszystkie sciany sa izolowane za pomoca materialu izolacyjnego 18. Kabina 17 ma drzwi (nie pokazane), przez które walec ma¬ gazynowy moze ibyc wkladany do i wyjmowany z tej kabiny. W kabinie 17 umieszczony jest ele¬ ment grzewczy 19, którym moze byc elektryczny element grzewczy do ogrzewania, wnetrza kabiny do pozadanej temiperatury. Temperatura moze byc nastawiana za pomoca termostatu 20 umieszczone¬ go na zewnatrz kabiny. Przed uzyciem walec 1 magazynowy z folia tworzywa sztucznego umiesz¬ cza sie w ogrzewanej kabinie i .nastawia sie tem¬ perature wnetrza kabiny za pomoca termostatu 20 w taki sposób, ze wnetrze kabiny ma temperature nizsza od temiperatury topnienia tworzywa sztucz¬ nego i korzystnie nastawiona ,na temperature od¬ powiadajaca 50—70% temperatury topnienia tego materialu. Walec 1 magazynowy pozostaje w ka¬ binie dopóty, az caly material folii osiagnie w za¬ sadzie temperature kabiny 17, na przyklad L14°C dla grubej <0,i2 mm) folii z polietylenu o wysokiej gestosci. Tuz przed momentem laczenia jednej wstegi folii z nastepna wstega, która moze byc wstega wlóknista, ogrzany walec 1 magazynowy wyjmuje .sie z kabiny i montuje w urzadzeniu do laminowania. Ogrzany walec 1 magazynowy za¬ wiera wstege 2 tworzywa sztucznego', która na przyklad jest wstega z polietylenu o wysokiej ge¬ stosci. Wstega przeznaczona do zlaczenia ze wste¬ ga 2 dla utworzenia laminatu nawinieta jest na walec 3 magazynowy, przy czyim w zilustrowanym wykonaniu jest to wstega 4 papieru,, na przyklad z papieru siarczanowego. Powierzchnia wstegi 4 papieru po stronie przeciwnej od srodka walca 3 magazynowego powleczona jest warstwa tworzywa sztucznego, na przyklad warstwe polietylenu o wysokiej gestosci.Wstege papieru 4 ciagnie sie z walca 3 magazy¬ nowego nad walcem luznym 5 i stamtad do walca luznego 6. Wstega papieru rozciaga sie od walca luznego 6 do dalszego walca luznego 8. W zilu7 strowanym wykonaniu, miedzy dwoma luznymi walcami 5 i 6 umieszczone sa dwa elementy grze¬ wcze 9 i 10 zasilane energia ze zródla energii 11.Elementy grzewcze 9 i 1© moga zawierac elektry¬ czne elementy oporowe ogrzewane do czerwonego 5 zaru, lub moga zawierac palniki gazowe. Cieplo dostarczane jest równomiernie do powierzchni wstegi 4 papieru, badz tez elementy 9 i 10 i war¬ stwa tworzywa sztucznego umieszczone sa naprze¬ ciw siebie po drugiej stronie wstegi (papieru i w l0 ten sposób doprowadza sie je do stanu kleistego.Chociaz mozliwe jest stosowanie grzania bezpo¬ srednio na powleczenie z tworzywa sztucznego, korzystnie jest ogrzewac powleczenie poprzez wste¬ ge papieru, gdyz w ten sposób akuimiuluje sie ^ wieksza ilosc ciepla.Ciepla wstega 2 folii tworzywa sztucznego (prze¬ chodzi pod luznym walcem 12 i stamtad nad wste* ga papieru 4 na luzny walec 8. Poniewaz powie¬ rzchnia wstegi papieru 4 naprzeciw wstegi two- 20 rzywa sztucznego jest bardzo goraca, na przyklad ma temperature 150°C, i powleczenie jest stopio¬ ne, uzyskuje sie dobry kontakt dla wymiany cie¬ pla miedzy obiema wstegami i cieplo przechodzi do wstegi 2 folii z masy zawierajacej wstege pa- 25 pieru i jego powleczenie. Chociaz nie pokazano, powleczenie na wstedze papieru 4 jest ciagle i po¬ krywa cala powierzchnie wstegi.Wstega 2 folii, która owinieta na walcu 1 ma¬ gazynowym ma temperature na przyklad 50—1(20°C 30 w zaleznosci od grubosci wsitegi folii, która ma w zasadzie taka sama temperature gdy dociera do stacji wywierania cisnienia 8* 13 jest w takim sta¬ nie, ze czasteczki w materiale reaguja natychmiast wymieniajac cieplo ze wstega papieru 4 i jego po- 3g wleczeniem. Warstwa laminarna po stronie zwró¬ conej do wstegi papieru zaczyna zatem natych¬ miast topniec i laczy sie z powleczeniem na wste¬ dze papieru 4.Próby praktyczne wykazaly, ze gdy poczatkowa 40 temperatura folii tworzywa sztucznego wynosi w przyblizeniu 108°C, otrzymuje sie doskonale wia¬ zanie obu materialów nawet gdy wstega folii za¬ wiera polietylen o wysokiej gestosci o grubosci 0,1'25 mm i porusza isie z szybkoscia 1 m/s. 45 Po zlaczeniu ze soba obu wsteg przepuszcza sie je pTzez urzadzenie do nawijania lub bezposred¬ nio do dalszego przerobu.Jesli z jakichkolwiek powodów laminowanie ma byc przeprowadzone w sposób nie ciagly wygodnie 50 bedzie umiescic wokolo walca 1 folii boks grzew¬ czy lub podobne urzadzenie w urzadzeniu do la¬ minowania zapobiegajac przez to spadkowi tempe¬ ratury do niepozadanego poziomu. Talki boks grze¬ wczy 21 przedstawiony jest na figurze. 55 W przypadku jesli wstepne ogrzewanie walca 1 nie jest wystarczajace mozliwe jest dodanie ko¬ niecznej dodatkowej energii cieplnej do folii przez, na przyklad, grzanie walca 12 do takiej tempera¬ tury, ze folia 2 opuszczajaca walec 12 uzyskuje 60 odpowiednia temperature dla doskonalego polacze¬ nia .sie z wstega 4.Ponadto nalezy zwrócic uwage, ze folia 2 two¬ rzywa sztucznego (sama moze byc laminatem. Na r przyklad folia moze byc arkuszem folii alumiinio- 65 wej na która nalozona jest warstwa tworzywa114 606 8 sztucznego wyzej wymienionego typu. Folia alumi¬ niowa jest w 'tym przypadku oczywiscie umiejsco¬ wiona na stronie warstwy tworzywa sztucznego nie przeznaczonej do zetkniecia ze wstega 4. Cie¬ plo .potrzebne do doprowadzenia folii tworzywa sztucznego do odpowiedniej 'temperatury moze byc dostarczone przez pole elektryczne tworzace pra¬ dy wirowe w folii aluminiowej, tak zeby ogrzac ja a zateni i folie tworzywa sztucznego.Zastrzezenia patentowe 1.
