Description

Sposób wytwarzania sztucznej skóry z jednoczesnym formowaniem na jej powierzchni elementów dekoracyjnych o zadanym ksztalcie Przedmiotem wynalazku jest sposób wytwarza¬ nia sztucznej skóry z jednoczesnym formowaniem na jej powierzchni elementów dekoracyjnych o za¬ danym ksztalcie, np. czesci skladowych obuwia, galanterii skórzanej i podobnych wyrobów, przez naniesienie na warstwie nosnika w postaci skóry, tkaniny lub podobnego wlóknistego tworzywa po¬ rowatej warstwy na bazie polichlorku winylu, oraz prasowanie w matrycy, z jednoczesnym dzialaniem podwyzszonej temperatury.Znany jest sposób wytwarzania sztucznej skóry z jednoczesnym formowaniem na niej elementów o okreslonych ksztaltach, polegajacy na pokry¬ ciu wykroju matrycy wykonanej z zywicy o niskim wspólczynniku strat dielektrycznych, warstwa ma¬ terialu porotwórczego w postaci cieklej, lub sprosz¬ kowanej, a nastepnie na ulozeniu na tej warstwie nosnika w postaci folii i na zzelowaniu materialu porotwórczego za pomoca pradów o wysokiej cze¬ stotliwosci.Sposób ten ma jednak wiele wad i niedogod¬ nosci ograniczajacych jego zastosowanie. Podczas parowania szybko nagrzewajacego sie plastyfika¬ tora lub innego srodka zawartego w materiale po- rotworczym powstaja pecherzyfei powietrzne, które umiejscawiaja sie w warstwie powierzchniowej wyrobu. Wyglad zewnetrzny wyrobu wytworzone¬ go tym sposobem jest nieodpowiedni przez co wy¬ rób ten musi byc jako brak odrzucony.Dla unikniecia tworzenia sie pecherzyków lub 10 15 30 baniek pozadane jest zeby objetosc materialu po¬ rotwórczego byla wyraznie wieksza od objetosci wykroju matrycy, z drugiej zas strony, z uwagi na swój stan i swa lepkosc, material porotwónufr zajmuje czesto wieksza objetosc od objetosci wy¬ kroju matrycy i w czasie sciskania tego materialu plastycznego nadwyzka wycieka na zewnatrz wy¬ kroju matrycy, tworzac wyplyw, iktóry trzeba usu¬ nac i odrzucic. Usuwanie i odrzucanie wyplywu jest dosc klopotliwe.Ponadto, w przypadku gdy wykrój matrycy ma postac zlozona stosowanie materialu porotwórczego w postaci pasty jest klopotliwe.Celem wynalazku jest usuniecie wyzej wymie¬ nionych wad i niedogodnosci.Cel ten uzyskano dzieki sposobowi wedlug wy¬ nalazku, którego istota polega na tym, ze warstwe piankowego tworzywa sztucznego wykonana na bazie polichlorku winylu przed nalozeniem na no¬ snik impregnuje sie polichlorkiem winylu w po¬ staci pasty lub proszku, przy czym matryce wy¬ konuje sie z materialu o malym wspólczynniku strat dielektrycznych.Przez prasowanie w matrycy z jednoczesnym dzialaniem podwyzszonej temperatury dokonuje sie scislego zwiazania skladników wyrobu przez sci¬ sniecie wykrojem matrycy impregnowanej war¬ stwy i warstwy nosnika. Do wywolywania pod¬ wyzszonej temperatury stosuje sie korzystnie pole elektryczne o wysokiej czestotliwosci, które wywo- 80 54580 545 3 luje ogrzewanie, zzelowanie i stopienie maiteria- lów w postaci proszku lub pasty oraz warstwy 7 materialu piankowego, powodujace zmieszanie sie wewnetrzne materialu piankowego z materia¬ lami impregnujacymi, znikniecie warstwy z ma¬ terialu piankowego i powstanie jednorodnego ma¬ terialu oraz polaczenie go z warstwa nosna.W czasie nacisku matrycy na uklad utworzony przez warstwe materialu piankowego i warstwe nosnika, warstwa z materialu piankowego zostaje zupelnie splaszczona przez brzegi wykroju matry¬ cy a warstwa nosnika zostaje tylko zdeformowa¬ na przez dno tej wnejki.Zgniecenie i deformacja powoduja równoczesne zelowanie, ciagle odprowadzenie powietrza zawar¬ tego w materiale plastycznym, którym jest impreg¬ nowana warstwa z materialu piankowego, pozwa¬ laja zatem osiagnac wyrób o identycznej powierz¬ chni i uksztaltowaniu jak wykrój matrycy.Fónadtó, w czasie deformacji i polaczenia, war¬ stwa materialu piankowego pochlania material im¬ pregnujacy i zapobiega wylewaniu sie go z wy¬ kroju, dzieki czemu osiaga sie artykul o najlep¬ szym wygladzie.Podczas zelowania, w czasie podnoszenia sie temperatury, warstwa z materialu piankowego miesza sie z proszkiem lub pasta tworzac jedno¬ rodna warstwe materialu.Korzystnie jest gdy warstwa materialu absorbu¬ jacego ma grubosc wyzsza od glebokosci wykroju matrycy.W celu podwyzszenia wytrzymalosci mechanicz¬ nej wyrobu miedzy wierzchnia warstwa z ma¬ terialu piankowego a spodnia warstwa nosna umieszcza sie druga warstwe z materialu o wla¬ snosciach róznych od pierwszej wierzchniej war¬ stwy materialu piankowego, która nie powinna sie roztapiac w temperaturze zelowania. Ta druga po¬ wloka powinna stanowic tkanine szklana, filc, ba¬ welne, kauczuk lub inny material tkany i powin¬ na sie polaczyc w wykroju matrycy z pierwsza wierzchnia powloka wyrobu.Te druga warstwe materialu prasuje sie w tym samym czasie co pierwsza, przez co po zzelowaniu staje sie ona integralna czescia wyrobu i tworzy jego zbrojenie zwiekszajace jego odpornosc me¬ chaniczna.Wyrób tak wykonany odznacza sie wieksza wy¬ trzymaloscia od wyrobu podobnego lecz nie po¬ siadajacego takiego zbrojenia.W celu uzyskania wyrobu o okreslonej barwie stosuje sie pigmenty o tych samych wlasciwos¬ ciach chemicznych co materialy tworzace warstwe materialu piankowego lecz o kolorze róznym od koloru warstwy i jej materialu impregnujacego.Pigmenty te wprowadza sie do calego obszaru wy¬ kroju matrycy lub do czesci, do warstwy materialu piankowego impregnowanego, aby w czasie zelo¬ wania te pigmenty polaczyly sie z innymi sklad¬ nikami materialu i zeby barwily caly wyrób lub w okreslonych miejscach.Na zalaczonym rysunku fig. 1 — przedstawia poszczególne warstwy wyrobu w przekroju, przed nadaniem mu przez wykrój matrycy zadanego ksztaltu, fig. 2 poszczególne warstwy w przekroju 4 po uformowaniu ich przez wyikrój matrycy, fig. 3, 4 i 5 przedstawiaja trzy przyklady wykonania urzadzenia do stosowania sposobu wedlug wyna¬ lazku w widoku z boku, z czesciowym przekrojem. 5 Na fig. 1 i 2 jest pokazany stempel Z ustawiony naprzeciwko przestawialnej pionowo matrycy 3, w której wykonany jest wykrój 4 o profilu i gle¬ bokosci odpowiadajacej wyrobom jakie sie chce otrzymac.Matryca 3 jest wykonana z materialu silikono¬ wego o malym wspólczynniku strat dielektrycz¬ nych, umozliwiajacego otrzymywanie bardzo wier¬ nej reprodukcji wyrobu.Ten material stanowi najlepiej kauczuk siliko¬ nowy wykazujacy slabe wlasnosci dielektryczne, zapobiegajace nagrzewaniu materialu wówczas gdy umieszczony jest w polu o wysokiej czestotliwosci.Ma on te zalete, ze zezwala na wyjmowanie z wykroju matrycy wyrobów wykonanych w sta¬ nie goracym. Ponadto ma on gietkosc umozliwia¬ jaca wykonanie wyrobów formowanych przy zbiez¬ nosciach ujemnych, a zwlaszcza umozliwia on bar¬ dzo wierne odtwarzanie wyrobu, to znaczy nie tyl¬ ko jego strukture lecz takze strukture jego po¬ wierzchni.Wyrób sklada sie z warstwy 5 materialu pian¬ kowego zwlaszcza z polichlorku winylu nalozonej na nosniku 6 ze skóry, tkaniny lub innego ma¬ terialu.Warstwa 5 materialu piankowego ma grubosc wieksza od grubosci wykroju matrycy i jest cal¬ kowicie zaimpregnowana znanym sposobem i ma¬ terialem w postaci pasty lub w postaci proszku szczególnie z chlorku winylu.Warstwa 5 i masa w postaci pasty lub proszku sa utworzone z materialu o tych samych wlasnos¬ ciach chemicznych. Moga sie one skladac z ma¬ terialów nie nalezacych do rodziny chlorku wi¬ nylu pod warunkiem, ze materialy te maja wysoki wspólczynnik strat dielektrycznych, pozwalajacy zelowac je za pomoca pradów wysokich czestotli¬ wosci.Gdy warstwe 5 polozona na nosniku 6 ustawi sie miedzy ruchomy stempel 2 i wykrój 4 matry¬ cy 3, pod dzialaniem sily nacisku material two¬ rzacy te powloke zostaje splaszczony przez brzegi 4a wykroju 4 i zdeformowany przez jego dno 4b, jak to jest przedstawione na fig. 2. Równoczesnie pod dzialaniem sily nacisku materialy plastyczne tworzace warstwe 5 i masa impregnujaca sa ze¬ lowane w okreslonej temperaturze przez prady wysokich czestotliwosci. Warstwa 5 z materialu piankowego miesza sie wewnetrznie z masa im¬ pregnujaca tworzac z ta masa jednorodny ma¬ terial plastyczny i laczy sie z warstwa nosnika 6.Warstwe nosnika 6 stosuje sie z materialu któ¬ rego wspólczynnik strat dielektrycznych jest taki sam pod dzialaniem pradu wysokiej czestotliwosci jak warstwa 5 z materialu piankowego.Jezeli przy zelowaniu materialu plastycznego formuja sie pecherzyki w materiale tworzacym warstwe 5 i wychodza z tego materialu to one przeszkadzaja temu materialowi plastycznemu wy¬ lac sie poza obrzeza wykroju matrycy na skutek dzialania sily cisnienia. 15 20 25 30 35 40 45 50 55 GO80 545 Warstwa 5 ma te wlasciwosc, ze zapewnia stop¬ niowe wchlanianie materialu plastycznego i utrzy¬ manie sie go, co ulatwia usuwanie pecherzyków powietrza podczas zelowania.Impregnacja warstwy 5 z materialu piankowego powinna byc wykonana przed i po jej osadzeniu na warstwie nosnika 6.Urzadzenie do stonowania sposobu stanowi tasma przenosnikowa 7 przesuwana w sposób ciagly w kierunku strzalki 8. Na stanowisku 9 warstwa nosnika 6 jest nakladana na tasmie przenosniko¬ wej 7. Na stanowisku 10 warstwa 5 z materialu piankowego jest nakladana na warstwe nosnika 6 i impregnowana przede wszystkim polichlorkiem winylu w postaci proszku.Na stanowisku 12, matryca 3 ze swym wykro¬ jem 4 skierowanym do dolu jest ustawiona na warstwie 5 i warstwie 6. Na stanowisku zelowa¬ nia 13 walki sciskajace 14 ustawione jeden nad drugim obracaja sie z szybkoscia stala odpowia¬ dajaca szybkosci przesuwu tasmy przenosniko¬ wej 7. Podczas przesuwu tasmy przenosnikowej 7 te walki sciskaja mocno warstwe 5 i 6. Te walki sciskajace sa wlaczone w obwód pradu wysokiej czestotliwosci dla utrzymania materialu w jego temperaturze zelowania.W przykladzie wykonania urzadzenia przedsta¬ wionego na fig. 4 walki sciskajace zastapione zo¬ staly przez dwie plyty 16 prasy mechanicznej lub hydraulicznej, które jednoczesnie sciskaja warstwe 5 zawarta miedzy matryca 3 i warstwa nosna 6 i równoczesnie zapewniaja zelowanie materialu za pomoca pradów wysokiej czestotliwosci. Kazda z tych plyt jest polaczona z jednym z zacisków obwodu pradu elektrycznego wysokiej czestotli¬ wosci.Przyklad wykonania urzadzenia przedstawionego na fig. 5 zawiera tasme przenosnikowa 7 prze¬ mieszczajaca sie w kierunku strzalki 8 na która jest doprowadzona ciagla warstwa nosnika 6a z odwijajacej sie cewki 17 oraz ciagla warstwa z odwijajacej sie cewki 18, Warstwa 6a i warstwa 5a przechodza miedzy dwoma sciskajacymi walkami 19, 20 z których wa¬ lek 20 impregnuje warstwe 5a, a nastepnie prze¬ chodzi miedzy dwoma walkami prasujacymi 22 i 23.Walek 23 jest wyposazony w wykladzine 23a z ma¬ terialu na bazie silikonu, który zawiera wykrój do wykonania wyrobu. Kazdy z tych walków 22, 23 jest równiez wlaczony za pomoca koncówek w obwód pradu elektrycznego o duzej czestotli¬ wosci.Wyroby 24 wytworzone w ten sposób sa na¬ stepnie rozdzielone jedne od drugich za pomoca prasy 25 zaopatrzonej w elementy zabierakowe, które rozcinaja warstwe 6.Urzadzenie to stosowane jest do wytwarzania ele¬ mentów wyrobów o bardzo znikomej grubosci rze¬ du 5/10 mm do 3 mm i szczególnie do wytwa¬ rzania elementów stosowanych do dekoracji obu¬ wia i innych, lecz urzadzenie to moze byc stoso¬ wane do fabrykacji grubszych elementów.W przykladzie wykonania najbardziej korzyst¬ nym, warstwe materialu piankowego impregnuje sie materialem w postaci pasty lub proszków z ma- 6 terialów o tych samych wlasciwosciach chemicz¬ nych lecz o róznych wlasciwosciach plastyfikuja- cych, to jest zawierajacych rózne proporcje plasty¬ fikatora. 5 Wyrób otrzymany po zzelowaniu za pomoca pra¬ du wysokiej czestotliwosci ma czesci gietkie odpo¬ wiadajace strefom zaimpregnowanym o najwiek¬ szej proporcji plastyfikatora oraz czesci sztywne odpowiadajace strefom zaimpregnowanym masa io o najmniejszej proporcji plastyfikatora.Sposób wedlug wynalazku ma te zalete, ze poz¬ wala wytwarzac wyroby posiadajace strefy sztyw¬ ne polaczone ze strefami sprezystymi w jednej operacji, szczególnie czesci obuwia zawierajace stre- 15 fy wzmocnione na przyklad obcas buta ze swoja kapka i przyszwa ze swoim koncem twardym.Równiez ta wlasciwosc pozwala na lokalne wzmoc¬ nienie pewnej czesci obuwia na przyklad sztyw¬ nosci partii surowych, zaleznie od ilosci uzytego 20 plastyfikatora, uzytej masy, grubosci warstwy ma¬ terialu impregnowanego i proporcji impregnatora uzytego do tej warstwy materialu.
