Description
Die Erfindung betrifft ein kontinuierliches Verfahren zum Verbinden von Schaumstoffbahnen, insbesondere aus thermoplastischen Kunststoffen, mit Trägerbahnen, z. B. aus Textilien, Kunststoffen oder Papier.The invention relates to a continuous process for joining foam sheets, in particular made of thermoplastics, with carrier webs, z. B. from textiles, plastics or Paper.
Schaumstoffe, z. B. Zellkörper mit geschlossenen Zellen, haben unter anderem die Eigenschaft, thermisch hervorragend zu isolieren. Schon sehr dünne Bahnen, z. B. solche von 2 bis 4 mm, eignen sich zum Ausfüttern von Kleidungsstücken. Hindernd wirkt jedoch bei dieser Verwendungsweise die allgemein geringe Festigkeit des Schaumstoffes. Es ist bereits bekanntgeworden, die Nähfestigkeit von Zellkörpermaterial dadurch zu erhöhen, daß man das Zellkörpermaterial mit leichten Textilstoffen vernäht. Dadurch wird aber nicht die Reißfestigkeit des Schaumstoffes vergrößert.Foams, e.g. B. Cell bodies with closed cells, among other things, have the property of being thermal excellent to insulate. Even very thin webs, e.g. B. those of 2 to 4 mm are suitable for lining items of clothing. However, the general effect has a hindering effect on this mode of use low strength of the foam. The sewing strength of cell body material has already become known by sewing the cell body material with lightweight fabrics. However, this does not increase the tear strength of the foam.
Es ist weiterhin bekannt, Schaumstoffbahnen mit lösungsmittelhaltigen Klebstoffen auf textlien Trägermaterialien zu befestigen. Solche Verfahren haben aber den Nachteil, daß entweder die Zellen des Schaumstoffes durch das Lösungsmittel beschädigt werden oder daß die Klebstelle durch Einwandern des Weichmachers, welcher in dem Schaumstoff enthalten ist, an Haftfestigkeit verliert. Schließlich kan es auch vorkommen, daß bei Verwendung einer lösungsmittelundurchlässigen Schicht, z. B. einer Kunststoffbahn, als Trägermaterial das Lösungsmittel nicht oder nur äußerst langsam verdampft, so daß keine oder nur eine ungenügende Verklebung erfolgt.It is also known to use foam webs with solvent-based adhesives on textile carrier materials to fix. However, such methods have the disadvantage that either the cells of the Foam can be damaged by the solvent or that the glue point by migration of the plasticizer contained in the foam loses its adhesive strength. In the end it can also happen that when using a solvent-impermeable layer, e.g. B. one Plastic sheet, as a carrier material, the solvent does not evaporate or only evaporates extremely slowly, so that no or insufficient gluing takes place.
Bekannt ist es auch, die Oberfläche eines thermoplastischen Schaumstoffes mittels Wärme zu erweichen und die Verklebung mit dem Trägermaterial unter Druck durchzuführen. Dieses Verfahren hat aber den Nachteil, daß die Zellenstruktur an der Oberfläche weitgehend zerstört wird, was sich auf die Eigenschaften des Fertigmaterials ungünstig, z. B. verhärtend auswirkt.It is also known to soften the surface of a thermoplastic foam by means of heat and to perform the adhesive bond with the carrier material under pressure. This procedure has but the disadvantage that the cell structure is largely destroyed on the surface, which affects the Properties of the finished material unfavorable, e.g. B. has a hardening effect.
Bekannt ist es außerdem, ein schmelzbares Kunststoffpulver mit Hilfe eines Trichters oder durch Aufstäuben auf eine Trägerbahn zu verteilen und dann die Trägerbahn mittels Wärme mit einer weiteren Schicht zu vereinigen. Bei dieser Maßnahme ist es aber schwierig, eine gute Verklebung der Trägerbahn mit der weiteren Schicht zu erreichen, weil weder der Trichter noch das Aufstäuben eine ausreichend gleichmäßige Verteilung des Kunststoffpulvers bewirken.It is also known to melt a plastic powder with the aid of a funnel or by dusting to distribute on a carrier web and then the carrier web by means of heat with another Unite layer. With this measure, however, it is difficult to achieve a good bond of the carrier web to be achieved with the next layer, because neither the funnel nor the dusting is sufficiently uniform Effect distribution of the plastic powder.
Es wurde nun ein Verfahren gefunden, welches es auf einfache Weise gestattet, die genannten Schwierigkeiten zu überwinden.A method has now been found which allows the stated difficulties to be overcome in a simple manner to overcome.

Textilien, Kunststoff, Papier, unter Verwendung eines thermoplastischen Kunststoffpulvers als Bindemittel, das auf die Trägerbahn aufgetragen, erweicht oder geschmolzen wird, wobei anschließend die mit Bindemittel versehene Trägerbahn mit der mit gleicher Geschwindigkeit und in gleicher Richtung laufenden Schaumstoffbahn unter Anwendung eines leichten Druckes vereinigt wird, ist erfindungsgemäß dadurch gekennzeichnet, daß das Kunststoffpulver mit Hilfe einer die Trägerbahn berührenden, sich drehenden Walze auf die Trägerbahn gleichmäßig aufgetragen wird.thermoplastics, with a flexible carrier web made of z. B. textiles, plastic, paper, using a thermoplastic plastic powder as a binder, which is applied to the carrier web is applied, softened or melted, then the carrier web provided with binder with the foam sheet running at the same speed and in the same direction Application of a slight pressure is combined, is characterized according to the invention in that the plastic powder with the aid of a rotating roller that touches the carrier web onto the carrier web is applied evenly.
Das Kunststoffpulver wird mittels einer umlaufenden Walze von einem mit Kunststoffpulver versehenen Behälter aufgenommen und auf die Trägerbahn übertragen. Vorzugsweise wird zu diesem Zweck eine Walze verwendet, deren Oberfläche nicht poliert ist.The plastic powder is provided with a plastic powder by means of a rotating roller Container picked up and transferred to the carrier web. Preferably a Used roller, the surface of which is not polished.
Die Dicke der Pulverschicht auf der Trägerbahn kann durch Bestimmung der Umlaufgeschwindigkeit der Walze eingestellt werden.The thickness of the powder layer on the carrier web can be determined by determining the rotational speed the roller can be adjusted.
Nach einer Ausführungsform der Erfindung dreht sich die Walze in entgegengesetzer Richtung zu der Bewegung der Trägerbahn.According to one embodiment of the invention, the roller rotates in the opposite direction to that Movement of the carrier web.

Es hat sich als günstig erwiesen, die Umfangsgeschwindigkeit der Wake 3- bis 8mal größer zu halten als die Bewegungsgeschwindigkeit der zu bepudernden Trägerbahn.It has proven to be beneficial to increase the peripheral speed of the wake 3 to 8 times higher hold than the speed of movement of the carrier web to be powdered.
Das Verfahren soll an Hand der nachstehenden Beispiele zur besseren Verständlichkeit dargestellt werden.The procedure is illustrated using the following examples for better understanding will.
1. Es soll eine Schaumstoffbahn aus weichgemachtem Polyvinylchlorid von etwa 3 mm Dicke mit einer Textilträgerbahn verbunden werden. Auf eine Kalikobahn, welche mit einer Geschwindigkeit von 60 m/h vorrückt, wird mit Hilfe einer nicht polierten Walze, welche sich mit einer Umfangsgeschwindigkeit von 300 m/h in einer der Bahnbewegung entgegengesetzten Richtung dreht, ein thermoplastisches Kunststoffpulver in Mengen von etwa 2 bis 5 g/m2 aus einem längs der Walze angeordneten Behälter aufgebracht. Verwendet wird ein Copolymerpulver aus 75 % Vinylchlorid und 25%· Vinylacetat, das beim Sieben mit einem Sieb von 0,06 mm Maschenweite einen Rückstand von etwa 17%· und einen Erweichungspunkt von etwa 65° C aufweist. Die so präparierte Textilträgerbahn wird mit der nicht bepuderten Seite über eine auf 140° C geheizte Walze geführt, so daß das Kunststoffpulver auf der anderen Fläche zerfließt. Anschließend wird mittels Walzen die Schaumstoffbahn unter leichtem Druck und unter gleichzeitiger Abkühlung auf den erweichten thermoplastischen Kunststoff der Trägerbahn aufgebracht. Die Abkühlung der erhaltenen Verbundbahn erfolgt z. B. durch Überleiten über eine luftgekühlte Kühlwalze. Man erhält auf diese Weise eine gut haftende, homogene und geschmeidige Verbindung von Schaumstoff und Textilbahn.1. A foam sheet made of plasticized polyvinyl chloride about 3 mm thick is to be connected to a textile backing sheet. A thermoplastic plastic powder in quantities of about 2 to 5 g / m 2 applied from a container arranged along the roller. A copolymer powder composed of 75% vinyl chloride and 25% vinyl acetate is used, which, when sieved with a sieve of 0.06 mm mesh size, has a residue of about 17% and a softening point of about 65.degree. The textile carrier web prepared in this way is guided with the non-powdered side over a roller heated to 140 ° C. so that the plastic powder melts on the other surface. The foam web is then applied to the softened thermoplastic of the carrier web by means of rollers under slight pressure and with simultaneous cooling. The composite web obtained is cooled, for. B. by passing over an air-cooled chill roll. In this way, a well-adhering, homogeneous and pliable connection between foam and textile web is obtained.
2. Eine Schaumstoffbahn soll mit einer Trägerbahn aus thermoplastischem Kunststoff verbunden werden. Auf eine Kunststoffbahn aus weichgemachtem Polyvinylchlorid mit Fließpunkt von etwa 80° C und von einer Stärke, wie sie für Fußbodenbeläge üblich ist, wird mit einer Walze ein Kunststoffpulver mit höchstens etwa 0,1 mm Korndurchmesser, bestehend aus einem Copolymerisat von 25 % Vinylacetat und 75 % Vinylchlorid, dessen Fließpunkt bei etwa 65° C liegt, aufgetragen. Die bepuderte Hache wird mit Infrarotlicht so weit bestrahlt, daß das Pulver, nicht aber die Trägerbahn zu fließen anfängt. Sobald das Pulver geschmolzen ist, wird eine Schaumstoffbahn von 2 bis 10 mm Stärke aus weichgemachtem Polyvinylchlorid mit leichtem Druck aufgebracht und anschließend im Luftstrom abgekühlt. Es entsteht ein weicher Bodenbelag.2. A foam sheet is to be connected to a carrier sheet made of thermoplastic material. On a plastic sheet made of plasticized polyvinyl chloride with a pour point of about 80 ° C and of a thickness, as it is common for floor coverings, a plastic powder with a roller with at most about 0.1 mm grain diameter, consisting of a copolymer of 25% vinyl acetate and 75% Vinyl chloride, the pour point of which is around 65 ° C, applied. The powdered hat is exposed to infrared light irradiated to such an extent that the powder, but not the carrier web, begins to flow. Once the powder melted, a foam sheet of 2 to 10 mm thick made of plasticized polyvinyl chloride applied with light pressure and then cooled in the air stream. There arises a soft flooring.
3. Es soll ein dreischichtiges Verbundgebilde aus einer 3 mm starken Schaumstoffbahn aus weichmacherhaltigem Polyvinylchlorid mit beidseits aufgebrachten Trikotbahnen hergestellt werden. Dies geschieht in entsprechender Weise, wie im Beispiel 1 beschrieben.3. It should be a three-layer composite structure made of a 3 mm thick foam sheet made of plasticizer-containing Polyvinyl chloride can be produced with tricot panels on both sides. this happens in a corresponding manner as described in Example 1.
Zunächst wird Kunststoffpulver auf eine Trikotbahn aufgebracht und erwärmt, worauf die Verbindung mit der Schaumstoffbahn hergestellt wird. Dann wird eine weitere Trikotbahn mit Kunststoffpulver versehen. Auch dieses wird erhitzt. Dann wird das zunächst hergestellte Doppelschichtgebilde aus der Schaumstoff bahn und der Trikotbahn mit der Schaumstoffseite mit der zweiten, mit erweichtem Kunststoffpulver versehenen Trikotbahn unter leichtem Druck verbunden. Es entsteht ein weiches und sehr flexibles Verbundmaterial.First, plastic powder is applied to a tricot sheet and heated, whereupon the connection is made with the foam sheet. Then another strip of jersey is made with plastic powder Mistake. This is also heated. Then the double-layer structure initially produced is made of the Foam sheet and the tricot sheet with the foam side with the second, with softened plastic powder provided tricot panel under light pressure. The result is a soft and very flexible one Composite material.
