Description

Verfahren zur Herstellung eines Schichtstoffes aus PolyurethankunststofE oder PolyurethanschaumstofE und einem anderen Material Die Erfindung betrifft ein Verfahren zur Herstellung eines Schichtstoffes aus einer Bahn aus Polyurethankunststoff oder Polyurethanschaumstoff und einem anderen bahnförmigen Material, wie beispielsweise einem Gewebe oder einer Kunststoffolie ohne Verwendung eines Klebstoffes.Process for the production of a laminate from polyurethane plastics or polyurethane foams and another material The invention relates to a Process for the production of a laminate from a sheet of polyurethane plastic or polyurethane foam and another sheet-like material, such as a fabric or a plastic film without the use of an adhesive.

Bei der Herstellung eines solchen Schichtstoffes ist die Verwendung eines Klebstoffes aus verschiedenen Gründen unerwünscht, beispielsweise weil die Kosten des Schichtstoffes sich durch die Verwendung eines Klebstoffes erhöhen, weil viel Klebstoffe von Schimmelpilzen und Insekten angegriffen werden, weil der Schichtstoff durch den Klebstoff versteift wird, d. h. die den beiden Materialien des Schichtstoffes eigene Biegsamkeit durch den Klebstoff verlorengeht, oder weil der Klebstoff von den für das Reinigen des Schichtstoffes verwendeten Waschmitteln oder Chemikalien angegriffen wird.When producing such a laminate, the use an adhesive undesirable for various reasons, for example because the The use of an adhesive increases the cost of the laminate because a lot of adhesives are attacked by mold and insects because of the laminate is stiffened by the adhesive, d. H. the two materials of the laminate own flexibility is lost due to the adhesive, or because the adhesive is from the detergents or chemicals used to clean the laminate is attacked.

Es ist bekannt, einen Polyurethankunststoff kurzfristig auf Schmelztemperatur zu erhitzen und dann ohne Klebstoff mit einem anderen Material zu einem Schichtstoff zu vereinigen. Abgesehen davon, daß die nach diesem Verfahren erzielte Verklebung für viele Verwendungszwecke eines, solchen Schichtstoffes nicht fest genug ist, weil nur die Ränder der Poren des Polyurethanschaums mit dem anderen Material verbunden werden, liegt der Schmelzpunkt von Polyurethan bei ungefähr 230° C, d. h. bei einer Tempi ratur, bei der viele Materialien, wie beispielsweise empfindliche Gewebe und Kunststoffolien, sengen oder in anderer Weise geschädigt werden.It is known to briefly heat a polyurethane plastic to its melting temperature to heat and then without glue with another material to form a laminate to unite. Apart from the fact that the bond achieved by this process such a laminate is not strong enough for many purposes, because only the edges of the pores of the polyurethane foam are connected to the other material the melting point of polyurethane is around 230 ° C; H. at a Temperature at which many materials, such as delicate fabrics and Plastic sheeting, singe or otherwise damaged.

Es wurde nun gefunden, daß bestimmte Polyurethankunststoffe und Polyurethanschaumstoffe, wenn man sie auf eine Temperatur erhitzt, die weit über dem Schmelzpunkt des Polyurethans liegt, beim Abkühlen bis zu einer Temperatur, die beträchtlich unterhalb des Schmelzpunktes des Polyurethans liegt, weich und klebend bleiben, d. h. eine Art unterkühlten Zustand annehmen, in dem sie auch mit empfindlichen Geweben, z. B. aus Polyamiden, Wolle oder anderen. Materialien, deren Zersetzungstemperatur unter dem Schmelzpunkt des Polyurethans liegt, verklebt werden können. Dabei wird eine feste Bindung zwischen den Schichten erzielt, und der erhaltene Schichtstoff ist weich und biegsam und wird weder von Schimmelpilzen oder Insekten noch von Waschmitteln oder den gewöhnlich für eine chemische Reinigung verwendeten Chemikalien angegriffen.It has now been found that certain polyurethane plastics and polyurethane foams, when heated to a temperature well above the melting point of the polyurethane is, on cooling to a temperature which is considerably below the melting point of the polyurethane lies, remain soft and adhesive, d. H. a kind of hypothermic condition assume by working with sensitive tissues, e.g. B. made of polyamides, wool or other. Materials whose decomposition temperature is below the melting point of the Polyurethane lies, can be glued. This creates a strong bond between the layers achieved, and the laminate obtained is soft and pliable and is not affected by mold or insects, detergents or ordinary Chemicals used for dry cleaning were attacked.

Das Verfahren gemäß der Erfindung zur Herstellung eines Schichtstoffes aus einer Bahn aus Polyurethankunststoff oder Polyurethanschaumstoff und einem anderen bahnförmigen Material, bei dem man eine Oberfläche der Polyurethanbahri durch Erwärmen klebend macht und das: andere Material auf die klebend gemachte Oberfläche aufbringt, ist dadurch gekennzeichnet, daß die Oberfläche der Polyurethanbahn schnell auf eine Temperatur erhitzt wird, die mindestens so weit über dem Schmelzpunkt des Polyurethans liegt, daß die Oberfläche der Polyurethanbahn mindestens teilweise abgebrannt wird, und anschließend das andere Material auf die Polyurethanbahn preßt.The method according to the invention for producing a laminate from a sheet of polyurethane plastic or polyurethane foam and another sheet-like material in which a surface of the polyurethane can be heated by heating makes adhesive and that: applies other material to the surface made adhesive, is characterized in that the surface of the polyurethane sheet quickly on a Temperature is heated at least as far above the melting point of the polyurethane lies that the surface of the polyurethane sheet is at least partially burned off, and then pressing the other material onto the polyurethane sheet.

Das Verfahren gemäß der Erfindung ist auf alle diejenigen Polyurethane anwendbar, die bei der beschriebenen Wärmebehandlung Zersetzungsprodukte ergeben, die bei einer Temperatur unter dem Schmelzpunkt des Polyurethans erstarren und in ausreichender Menge zurückbleiben, um die erwünschte feste Bindung zu erzielen.The method according to the invention is applicable to all those polyurethanes applicable, which result in decomposition products during the heat treatment described, which solidify at a temperature below the melting point of the polyurethane and in sufficient amount remain to achieve the desired tight bond.

Es ist nicht genau bekannt, welche Eigenschaften es sind, die ein Polyurethan für die Anwendung des Verfahrens, gemäß der Erfindung geeignet machen. Polyurethanschäume aus den bekannten Polyestern haben den erforderlichen niedrigen Verdampfungspunkt, während die aus den meisten der bekannten Polyäther erhaltenen Polyurethanschäume keinen ausreichend niedrigen Verdampfungspunkt besitzen. Vermutlich kann die Wärmebehandlung gemäß der Erfindung mit Erfolg auf alle diejenigen Polyurethanschäume angewandt werden, die eine cyclische Molekülkette haben. Ob ein bestimmtes Polyurethan sich für die Herstellung eines Schichtstoffes nach dem Verfahren der Erfindu4g eignet, -läßt sich leicht durch einen einfachen Versuch feststellen.It is not known exactly what properties it is that make one Make polyurethane suitable for the application of the method according to the invention. Polyurethane foams made from the known polyesters have the required low Evaporation point, while those made from most of the known polyethers polyurethane foams obtained do not have a sufficiently low evaporation point. Presumably, the heat treatment according to the invention can be successfully applied to all of them Polyurethane foams are used, which have a cyclic molecular chain. If a certain polyurethane is used for the production of a laminate according to the process The invention is suitable, -can be easily determined by a simple experiment.

Die nach dem Verfahren gemäß der, Erfindung erhaltenen Polyurethanschichtstoffe eignen sich z. B. für die Herstellung von Mänteln und anderen Kleidungsstücken sowie als Futter für Kleidungsstücke, als Teppichunterlagen, je nachdem, aus welchem Material die mit der Polyurethanschaumbahn verklebte andere Bahn besteht.The polyurethane laminates obtained by the process according to the invention are suitable e.g. B. for the manufacture of coats and other garments as well as lining for items of clothing, as carpet underlays, depending on the material the other web is glued to the polyurethane foam web.

Auch nicht geschäumtes Polyurethan kan für die Herstellung eines Schichtstoffes nach dem Verfahren gemäß der Erfindung verwendet werden und ist beispielsweise in Verbindung mit einer Lederschicht für Schuhsohlen verwendbar.Non-foamed polyurethane can also be used to produce a laminate be used according to the method according to the invention and is for example in Can be used in conjunction with a leather layer for shoe soles.

Das Erhitzen der Polyurethanbahn kann mit jeder geeigneten Heizvorrichtung erfolgen. Bei einer speziellen Durchführungsform des Verfahrens gemäß der Erfindung wird zum Erhitzen der Polyurethanbahn die bandförmige Flamme eines langgestreckten und quer über der Polyurethanbahn angeordneten Gasbrenners verwendet, die direkt auf die zu erhitzende Fläche auftrifft.The polyurethane sheet can be heated with any suitable heating device take place. In a special embodiment of the method according to the invention the belt-shaped flame of an elongated one is used to heat the polyurethane sheet and a gas burner arranged across the polyurethane sheet, which directly hits the surface to be heated.

Zur Erzielung einer optimalen Bindungsfestigkeit zwischen den beiden Schichten kann es zweckmäßig sein, die Schicht aus dem anderen Material vorzuwärmen, bevor sie mit der Polyurethanschicht zusammentrifft, so daß ein Abschrecken der Polyurethanoberfläche vermieden wird.To achieve optimal bond strength between the two Layers, it can be useful to preheat the layer made of the other material, before it meets the polyurethane layer, so that a quenching of the Polyurethane surface is avoided.

Die beiden Bahnen müssen einander natürlich in der Weise zugeführt werden, daß die erhitzte Oberfläche der Polyurethanbahn erst dann mit der zweiten Bahn zusammentrifft, wenn sie eine mit dem anderen Material verträgliche Temperatur angenommen hat. Beispiel Eine Bahn aus Polyurethanschaumstoff mit einer , Dicke von 0,32 cm wurde mit einer Geschwindigkeit von 13,7 m/min unter einem langgestreckten, quer über der Oberfläche der Polyurethanbahn angeordneten Gasbrenner durchgeführt und dann mit einer Bahn aus einem Polyanüdtricotgewebe von 0,018 cm Dicke vereinigt. Dabei wurde ein. weicher, biegsamer Schichtstoff erhalten.The two tracks must of course be fed to one another in this way be that the heated surface of the polyurethane sheet only then with the second Web meets when it reaches a temperature compatible with the other material has accepted. Example A sheet of polyurethane foam with a thickness 0.32 cm was moved at a speed of 13.7 m / min under an elongated, carried out across the surface of the polyurethane sheet arranged gas burners and then combined with a sheet of polyanide tricot fabric 0.018 cm thick. It was a. soft, pliable laminate obtained.

Bei Veränderung der Temperatur der Brennerflamme durch Veränderung des Druckes der dem Brenner zugeführten Luft wurden die folgenden Werte für die Flammtemperatur 1,6 mm über der Oberfläche derPolyurethanschaumstoffbahn, dieDicke der abgebrannten Schicht und die Festigkeit der Bindung zwischen den beiden Schichten in dem erhaltenen Schichtstoff gemessen: Flammtemperatur 1,6 mm über der Oberfläche der Polyurethanbahn, ° C 984 1 1030 1 1087 Dicke der abgebrannten Schicht, cm ............. 0,053 0,071 0,081 Bindungsfestigkeit, kg/cm ... 0,0598 0,2045 0,295 Wenn die Polyurethanbahn mit einer Geschwindigkeit von 33 m/min unter dem Brenner hindurchgeführt wurde und die Flammtemperatur 1,6 mm über der Oberfläche der Polyurethanbahn 935° C betrug, so wurde eine Schicht von nur 0,015 cm Dicke abgebrannt, und die Bindungsfestigkeit betrug 0,0191 kg/cm.When the temperature of the burner flame was changed by changing the pressure of the air supplied to the burner, the following values were measured for the flame temperature 1.6 mm above the surface of the polyurethane foam sheet, the thickness of the burned layer and the strength of the bond between the two layers in the laminate obtained: Flame temperature 1.6 mm above the surface of the Polyurethane sheet, ° C 984 1 1030 1 1087 Thickness of the burned Layer, cm ............. 0.053 0.071 0.081 Bond Strength, kg / cm ... 0.0598 0.2045 0.295 When the polyurethane sheet was passed under the burner at a speed of 33 m / min and the flame temperature was 1.6 mm above the surface of the polyurethane sheet 935 ° C, a layer only 0.015 cm thick was burned off and the bond strength was 0. 0191 kg / cm.
