Description
"Verfahren zur Herstellung eines mehrschichtigen 2chaumstoffkunstleders" Die ##rfindun- betrifft ein Verfahren zur Herstellung C> eines mehrschichtigen Schaumstoffkunstleders. zahaumstoffkunstleder aus mit Schaumstoff kaschierter Kunststoffolie sind bekannt. Die Herstellung erfolgte in der Weise, dass die Oberfläche einer Polyurethanbahn durch :Wrwärmen klebend gemacht und das andere bahnförinige iviaterial auf die klebend gemachte Oberfläene aufgebracht wird."A process for producing a multilayer 2chaumstoffkunstleders" The ## rfindun- relates to a method for producing C> a multilayer foam artificial leather. Zahaumstoffkunstleder made of plastic film laminated with foam are known. The manufacture was carried out in such a way that the surface of a polyurethane sheet is made adhesive by: heating and the other sheet-like material is applied to the surface made adhesive.
Die j#rfindung bezweckt die Schaffung eines Verfahrens zi)r eines mehrschichtigen ;jchaumstoffkunstleders besteh2nd aus einer mit Gchaumstoff kaschierten KunGtstoffolie, welches einfach durcazuführen ist und zu einem Produkt führt9 welches geg ,enüber den bekannten 1-rodukten diescr ürt Vorteile aufweist, insbesondere spezifisches Gewicht und eine ungewöhnli-1"G%beniiber den handelsäblichen Reinigungrsmitteln, wie z.b. in clorierten Kohlenwasserstoffen und waschaktiven Substanzen.The aim of the invention is to create a process for one multilayer; foam synthetic leather consisting of one laminated with foam Plastic film that is easy to feed through and leads to a product9 which Compared to the known 1 products this has advantages, in particular specific weight and an unusual 1 "% by weight above standard cleaning agents, how e.g. in chlorinated hydrocarbons and detergent substances.
Der Erfindungszweck wird dadurch erreicht, dass auf eine beidseitig angeschmolzene Schaumstoffbahn auf ihrer einen beite eine angewärmte Deckschichtbahn und auf ihrer anderen Seite eine L-#.bseitebahn gleichzeitig unter Druck und Gegendruck aufgebracht ZD wird.The purpose of the invention is achieved in that on both sides fused foam sheet on one side of a heated top layer sheet and on its other side an L - #. side panel simultaneously under pressure and counter pressure ZD is applied.
hach einem weiteren läerkmal der Erfindung wird die Deckschichtbahn beim i,.ufbringen auf die Schaumstoffbahn gleichzeitig geprägt.Another feature of the invention is the cover sheet when i, .application is simultaneously embossed on the foam sheet.
Falls die Abseitebahn aus einer Kunststoffolie besteht kann sie nach einem weiteren Merkmal der Erfindung vor dem Aufbringen auf die Schaumstoffbahn vorgewärmt werden.If the offside sheet consists of a plastic film, it can after another feature of the invention prior to application to the foam sheet be preheated.
Eine Ausführungsform zur Durchführung des erfindungsgemässen Verfahrens ist in der beigefügten Zeichnung dargestellto Die Polyurethan-Schaumstoffbahn 1 wird durch zwei Gasbrenner 2, 3 beidseitig angeschmolzen. Die Gasbrenner verlaufen quer zur Warenlaufrichtung. Unmittelbar hinter den Gasbrennern wird auf die eine Seite der Bahn 1 eine angewärmte Deckschichtbahn 4 und auf die andere Seite der Bahn 1 eine Abseitebahn 5 gleichzeitig unter Druck und Gegendruck aufgebracht und zwar mittels eines Zweiwalzen-Kalanders 6, 7. Die Vereinigung der drei Bahnen erfolgt durch den Anpressdrucka Anstelle der Folien-Anpresswalze 6 kann eine gemusterte Prägedruckwalze angeordnet werden, so dass in einem iLrbeitsdurchgang gleichzeitig die Oberfläche der Folie geprägt wird. Durch das Anschmelzen der Polyurethan-Schaumstoffbahn 1 wird ein Teil dieser Bahn beidseitig in ein kurzzeitiges thermoplastisches Stadium gebracht. In Verbindung mit der bereits durch andere Wärmeauellen wie z.B. Infrarotstrahler vorDlastizierten Kunststoff-Folie und der Prägewalze 6 kann man die Oberfläche des Verbundstoffes während seiner Herstellung gleichzeitig prägen. i#Iach dem Vereinigen und Verprägen kühlt die Verbundbahn lo unter Kühllufteinwirkung ab. Hierdurch wird das Prägebild fixiert. Diese Fixierung bzw. Permanenz wird durch die unterschiedlichen Erweichungspunkte der Thermoplaste ge-Senüber der Polyurethan-Schaumstoffbalm 1 erzielt. So liegt beispielsweise der Erweichungspunkt einer CD , 0 PVC-Folie bei So 09 während die Erweichungstemperatur eines 2#olyurethan-Schaumstoffes etwa 23o 0 0 beträgt. Durch den weitaus hÖheren Erweichungspunkt der Schaumstoffbblin ergibt sich die Stabilisierung-. Jie Deckschicht 4 kann aus einer thermoplastischen Yolie, z.L. PVGe Polyaethylen, Polypropylen, Polyamid od. df-,1. oder einer duroplastischen Folie, z.3. 1,olyester od. dt-1- bestehen.An embodiment for carrying out the method according to the invention is shown in the accompanying drawing. The polyurethane foam sheet 1 is melted on both sides by two gas burners 2, 3. The gas burners run transversely to the direction of movement of the goods. Immediately behind the gas burners, a heated top layer web 4 is applied to one side of the web 1 and an off-side web 5 is applied simultaneously to the other side of the web 1 under pressure and counterpressure by means of a two-roll calender 6, 7. The three webs are combined By means of the contact pressure Instead of the foil pressure roller 6 , a patterned embossing pressure roller can be arranged so that the surface of the foil is simultaneously embossed in one work pass. By melting the polyurethane foam web 1 , part of this web is brought into a brief thermoplastic stage on both sides. In connection with the plastic film already plasticized by other sources of heat such as infrared radiators and the embossing roller 6 , the surface of the composite material can be embossed at the same time during its manufacture. After combining and embossing, the composite web lo cools under the action of cooling air. This fixes the embossed image. This fixation or permanence is achieved through the different softening points of the thermoplastics over the polyurethane foam sheet 1 . For example, the softening point of a CD , 0 PVC film is So 09, while the softening temperature of a 2 # polyurethane foam is around 23o 0 0 . The stabilization results from the much higher softening point of the foam blanket. The cover layer 4 can be made of a thermoplastic film, e.g. PVGe polyethylene, polypropylene, polyamide or df-, 1. or a thermosetting film, e.g. 3. 1, olyester or dt-1.
Die j.#bseitebahn kann aus textilen materialien wie z.3. Zellwolle> baumwolle, Wolleg Viskose-Reyon, Kunstfasern wie unter den geschützten Namen Perlor bzw. Eylon bzw. Orlon bekannt, Polyacrylnitrile Polyester oder deren Lischungen als dirkware, Strick,-ware, Webware oder einem Vliesstoff bestehen.The j. # Side panel can be made of textile materials such as 3.

Es besteht ferner auch die lÖglichheite fÜr die Abseitebahn 5 thermoplastische oder duroplastische Folien Ve fÜr die Deckschichtbahn 4 zu verwendenäThere is also the possibility of using 5 thermoplastic or thermosetting foils for the outer layer web 4 for the off-side web
