Gemäß der Erfindung wird ein Verfahren zur Behandlung eines normalerweise nicht-schweißbaren synthetischen Kunststoff ^fa^berials, um dieses schweißbar zu machaa, geschaffen, bei welchem man auf ein derartiges Material eine verschäumte wäßrige Emulsion, die ein thermoplastisches Polymerisat enthält, aufbringt, und trocknet oder die Emulsion trocknen läßt, wobei das thermoplastische Polymerisat auf dem synthetischen Kunstoffmaterial abgeschnitten wird. Normaler-According to the invention there is provided a method of treating a normally non-weldable synthetic plastic ^ fa ^ berials, to make this weldable machaa, created, in which a foamed aqueous emulsion, which is a thermoplastic polymer, is applied to such a material contains, applies, and dries or allows the emulsion to dry, the thermoplastic polymer on the synthetic Plastic material is cut off. Normal

weise besteht das nicht-schweißbare synthetische Kunstoffmaterial aus einem verschäumten biegsamen Kunststoffmaterial, beispielweise einem Polyäthar- oder Polyesterschaum.the non-weldable synthetic plastic material consists of a foamed flexible plastic material, for example a polyethylene or polyester foam.
Die wäßrige Emulsion des thermoplastischen Polymaisats kann verschäumt werden, indem man ein oberflächenaktives Mittel zugibt, und Luft in die Emulsion durch Rühren bei hoher Geschwindigkeit einschlägt. Andererseits kann eine kontinuierliche Versehäumungsvorrichtung angewendet werden.The aqueous emulsion of the thermoplastic polymaisate can be foamed by adding a surfactant and air into the emulsion by stirring high speed. On the other hand, a continuous seaming device can be used.
Jegliche Verschäumte Flüssigkeit umfaßt etwa kugelförmige Tröpfchen von der Flüssigkeit, da diese Gestalt die geringste Menge an Energie erfordert. Biese Erscheinung wird gemäß der Erfindung in vorteilhafter Weise zur Regelung der Eindringufagstiefe des thermoplastischen Polymerisats in den Terschäumten Polyäther- oder Polyesterkunststoff angewendet. Das Verschämmen ergibt gemische von geringer Dichte,Any foamed liquid will comprise roughly spherical droplets of the liquid, since this shape requires the least amount of energy. Piping E r failed voltage is applied according to the invention in an advantageous manner to control the Eindringufagstiefe of the thermoplastic polymer in the Terschäumten polyether or polyester plastic. The blending results in mixtures of low density,

Beispiele für geeignete Wasseremulsionen, die gemäß der der Erfindung zur Anwendung gelangen, sind die folgenden:Examples of suitable water emulsions, according to the of the invention are used, are the following:
(1) Emulsionen von Acrylsäure- und Acrylestergomopolymerisaten und -mischpolymerisaten, beispielsweise PoIybutylacrylat und Mischpolymerisate von Butylacrylat und Vinylbutylätheremulsionen. Die letzteren Mischpolymerisate sind im Handel unter der Warenbezeichnung Acronale erhältlich.(Hergestellt von BASF).(1) Emulsions of acrylic acid and acrylic ester homopolymers and copolymers, for example polybutyl acrylate and copolymers of butyl acrylate and vinyl butyl ether emulsions. The latter copolymers are commercially available under the trade name Acronale. (Manufactured from BASF).
£2) Emulsionen von Vinylhomopolymer-Isaten und -etischpolymerisaten oder Mischungen von Acronalen mit Emulsionen von Vinylhomopolymerisaten oder -mischpöifeymerisaten.£ 2) Emulsions of vinyl homopolymer isates and synthetic polymers or mixtures of acronals with emulsions of vinyl homopolymers or mixed polymers.
(3) Selbstvernetzende AcrylharBemulsionen oder ein Gemisch von derartigen Harzen mit Vinylhomopolymerisat- oder Vinylmischpolymerisatemulsionen,(3) Self-crosslinking acrylic resin emulsions or a Mixture of such resins with vinyl homopolymer or Vinyl copolymer emulsions,
