   Formstabilisierter Körper aus Fasermaterial enthaltendem Polyurethanschaumstoff sowie Verfahren zu dessen Herstellung 
Die Erfindung bezieht sich auf formstabilisierte Polyurethan-Schaumstoffkörper, insbesondere in Form von Gebrauchsgegenständen, sowie auf ein Verfahren zu deren Herstellung. Die erfindungsgemässen formstabilisierten Schaumstoffkörper können   in Form von Polyesterkörpern z. B. für Autositze,   als elastische Unterlagen, Matratzen usw. Verwendung finden. 



   Die Verwendung von Schaumstoffen aus natürlichem oder synthetischem Kautschuk sowie aus schäumbaren Kunststoffen, wie z. B. Polyvinylchlorid, Polyestern u. dgl., zur Herstellung von elastischen oder unelastischen Schaumstoffen ist bereits bekannt. Derartigen Schaumkörpern haftet, wenn sie aus 
 EMI1.1 
 artige Polsterkörper in Fahrzeugen angebracht werden, sogar unter Umständen eine Gefährdung durch Hervorrufung eines Unsicherheitsgefühls des Fahrers hervorrufen können. 



   Um diesem Übelstand abzuhelfen, wurde bereits versucht, Schaumgummi sowie auch Polyätheroder Polyesterschaumstoffe stabilisierend zu verformen. Dabei wurde versucht, die Stabilisierung durch eine besondere Anordnung von Hohlräumen in dem Schaumstoffkörper zu erreichen. Derart hergestellte Schaumstoffkörper konnten jedoch noch immer nicht in ihren Eigenschaften völlig befriedigen. 



   Es ist weiterhin bereits seit langem bekannt, aus imprägnierten Fasermaterialien, sogenanntem Gummi- oder Krollhaar, elastische Formkörper herzustellen, die eine ausgezeichnete Formstabilität aufweisen, jedoch in der Herstellung relativ teuer kommen. Bei derartigen Faserkörpern sind die einzelnen Fasern von einer dünnen Gummi-oder Kunstharzschicht überzogen und durch diese dünne Schicht an ihren Berührungspunkten mit andern Fasern festhaftend verbunden, so dass daraus ein einheitlicher Körper mit ausgezeichneten elastischen Eigenschaften resultiert. 



   Es ist schliesslich ebenfalls bereits bekannt, Schaumstoffkörper herzustellen, welche durch Fasermaterialien verstärkt sind ; bei Herstellung derartiger Schaumstoffkörper wird beispielsweise das Fasermaterial, wie beispielsweise Haar, Kokosnussfaser,   Asbest-oder Zellulosefaser,   in einer Behälter gebracht und eine schäumbare Dispersion in diesem Behälter unter dem Einfluss einer Druckherabsetzung aufschäumen gelassen, wobei ein schaumartiges Gebilde aus Kautschuk oder kautschukartigem Material, das durch Fasern verstärkt ist, erhalten wird.   DerartigenKörpern   haftet jedoch vor allem der Nachteil an, dass die verstärkenden Fasern im fertigen Produkt nicht gleichmässig verteilt sind, sondern durch das Schäumen des Schaumstoffes im Körper ungleichmässig angeordnet werden.

   Eine gleichmässige Verteilung der Fasermaterialien könnte höchste durch ganze dichte Packung des Haarmaterials in der Form erreicht werden, wodurch jedoch einerseits das Produkt wieder gewaltig verteuert wird und anderseits die Möglichkeit besteht, dass bei einer derartig dichten Packung der Schaumstoff nicht gleichmässig über das ganze Formgebilde verteilt wird. 



   Es wurde nun überraschenderweise gefunden, dass man formstabilisierte Polyurethanschaumstoffkör- 

 <Desc/Clms Page number 2> 

 per, die die bisher in Kauf zu nehmenden Nachteile nicht aufweisen, und in denen haariges bzw. fa-   seriges Material völlig gleichmässig   als elastische Verstärkung eingeschlossen ist, erhalten kann, wenn man einen Formkörper aus   Gummi-oder Krollhaar   oder aus tierischen, pflanzlichen oder synthetischen W irrfasern vergleichbarer Dimension, welche Fasern mit einem im trockenen Zustand elastischen Bindemittel, vor- zugsweise Kautschuk, wenigstens an den gegenseitigen Berührungsstellen überzogen sind und dadurch in mehr oder weniger sperrigem, lockerem Gefüge zusammengehalten werden,

   gegebenenfalls unter geringfügiger
Kompression in eine Form bringt und diese Form nach Verschliessen mit einem elastischen Polyurethan- schaumstoff unter Druck ausschäumt. Es können hiefür alle treibfähigen Mischungen, welche sich zur
Herstellung von Schaumkörpern an sich eignen, Verwendung finden. 



   Die Erfindung betrifft auch formstabilisierte Körper aus   FasermaterialenthaltendemPolyurethan-   schaumstoff, welche dadurch gekennzeichnet sind, dass das Fasermaterial ein dreidimensionales Gerüst aus Gummi- oder Krollhaar oder aus tierischen, pflanzlichen oder synthetischen Wirrfasern vergleich- barer Dimension bildet, wobei die Fasern wenigstens an ihren gegenseitigen Berührungsstellen mit einem im trockenen Zustand elastischen Bindemittel, vorzugsweise Kautschuk, überzogen und somit miteinander verbunden sind, und der freie Raum innerhalb des gebundenen Wirrfasergebildes durch einen elastischen Polyurethanschaumstoff zur Gänze ausgefüllt ist. 



   Bei Herstellung der erfindungsgemässen Schaumstoffkörper kann es sich als zweckmässig erweisen, den Faserkörper so in den Formkasten einzubringen, dass an einer oder mehreren Seiten des Faserkörper zwischen diesem und der Wand des Formkörpers ein freier Raum verbleibt, der dann beim Ausschäumen des Formkastens mit unverstärktem Schaumstoff gefüllt wird. 



   Nach dem   erfindungsgemässen   Verfahren lassen sich die Mengenverhältnisse von Faserkörper zu
Schaumstoff innerhalb praktisch beliebiger Grenzen variieren, ohne dass dabei die Gleichmässigkeit des erhaltenen Formkörpers leiden würde. Es lassen sich dabei formstabilisierte Schaumkörper geringerer oder höherer Härte bzw. Dichte in praktisch jedem gewünschten Verhältnis von Verstärkungsfasern zu
Schaumstoff herstellen. Es ist nach dem erfindungsgemässen Verfahren unter anderem auch möglich, für dieses Verfahren beispielsweise Krollhaar mit höheren Mengen an elastischen Bindemitteln zu versehen, als es bisher möglich war. 



   Gemäss der Erfindung lassen sich beispielsweise elastische Polsterkörper ohne jeglichen Abfall und ohne dass die elastischen Polsterkörper zum "Schwimmen" neigen, sehr rationell und billig herstellen. 



   Das folgende Beispiel soll die Erfindung erläutern, ohne dass diese jedoch hierauf beschränkt sein soll. 



   Beispiel : In eine zur Herstellung von Schaumkörpern verwendete Form mit einer Grösse von 90 x 60 x 10 cm wird ein entsprechendes Formstück aus mittels kautschuklose gebundenem Krollhaar, ein sogenannter Gummihaarkörper, eingebracht und die Form wird nach Verschliessen mit etwa 2kg eines   Polyäther-Isocyanat-Reaktionsgemisches   ausgeschäumt. Nach Öffnen der Form wird ein formstabilisierter Schaumstoffkörper erhalten, der in keiner Weise zum Schwimmen neigt und eine Dichte von etwa 40   kg/m3   besitzt. 



    PATENT ANSPRÜCHE :    
1. Formstabilisierter Körper aus Fasermaterial enthaltendem Polyurethanschaumstoff, dadurch gekennzeichnet, dass das Fasermaterial ein dreidimensionales Gerüst aus Gummi- oder Krollhaar oder aus tierischen, pflanzlichen oder synthetischen Wirrfasern vergleichbarer Dimension bildet, wobei die Fasern wenigstens an ihren gegenseitigen Berührungsstellen mit einem im trockenen Zustand elastischen Bindemittel, vorzugsweise Kautschuk, überzogen und somit miteinander verbunden sind, und der freie Raum innerhalb des gebundenen Wirrfasergebildes durch einen elastischen Polyurethanschaumstoff zur Gänze ausgefüllt ist.

   Shape-stabilized body made of polyurethane foam containing fiber material and a process for its production
The invention relates to shape-stabilized polyurethane foam bodies, in particular in the form of articles of daily use, and to a method for their production. The inventive shape-stabilized foam bodies can be in the form of polyester bodies, for. B. for car seats, as elastic pads, mattresses, etc. use.



   The use of foams made from natural or synthetic rubber and from foamable plastics, such as. B. polyvinyl chloride, polyesters and. Like., For the production of elastic or inelastic foams is already known. Such foam bodies stick when they are off
 EMI1.1
 like cushion bodies are attached in vehicles, even under certain circumstances can cause a hazard by causing a feeling of insecurity in the driver.



   In order to remedy this disadvantage, attempts have already been made to deform foam rubber and also polyether or polyester foams in a stabilizing manner. Attempts were made to achieve stabilization through a special arrangement of cavities in the foam body. However, foam bodies produced in this way were still not entirely satisfactory in terms of their properties.



   It has also been known for a long time to produce elastic molded bodies from impregnated fiber materials, so-called rubber or curly hair, which have excellent dimensional stability but are relatively expensive to produce. In such fiber bodies, the individual fibers are covered by a thin rubber or synthetic resin layer and are bonded to other fibers by this thin layer at their points of contact, so that a uniform body with excellent elastic properties results.



   Finally, it is also already known to produce foam bodies which are reinforced by fiber materials; In the production of such foam bodies, for example, the fiber material, such as hair, coconut fiber, asbestos or cellulose fiber, is placed in a container and a foamable dispersion is allowed to foam in this container under the influence of a reduction in pressure, a foam-like structure made of rubber or rubber-like material which reinforced by fibers is obtained. Such bodies, however, have the main disadvantage that the reinforcing fibers are not evenly distributed in the finished product, but are instead arranged unevenly in the body due to the foaming of the foam.

   A uniform distribution of the fiber materials could be achieved by a tight packing of the hair material in the mold, which on the one hand makes the product much more expensive and on the other hand there is the possibility that with such a tight packing the foam is not evenly distributed over the entire shape .



   It has now surprisingly been found that shape-stabilized polyurethane foam bodies

 <Desc / Clms Page number 2>

 per, which do not have the disadvantages to be accepted up to now, and in which hairy or fibrous material is completely evenly enclosed as elastic reinforcement, can be obtained if a molded body made of rubber or curly hair or of animal, vegetable or synthetic material Tangled fibers of comparable dimensions, which fibers are coated with a binding agent that is elastic in the dry state, preferably rubber, at least at the points of mutual contact and are thus held together in a more or less bulky, loose structure,

   possibly under minor
Bringing compression into a mold and after closing it, foaming it with an elastic polyurethane foam under pressure. All propellant mixtures, which are used for
Production of foam bodies per se are suitable, find use.



   The invention also relates to shape-stabilized bodies made of polyurethane foam containing fiber material, which are characterized in that the fiber material forms a three-dimensional framework made of rubber or curly hair or of animal, vegetable or synthetic tangled fibers of comparable dimensions, the fibers at least at their points of mutual contact with an elastic binding agent in the dry state, preferably rubber, are coated and thus connected to one another, and the free space within the bound tangled fiber structure is completely filled by an elastic polyurethane foam.



   When producing the foam bodies according to the invention, it can prove to be expedient to introduce the fiber body into the molding box in such a way that a free space remains on one or more sides of the fiber body between this and the wall of the molding, which is then filled with unreinforced foam when the molding box is filled with foam becomes.



   According to the method according to the invention, the proportions of fiber bodies can be determined
Foam can vary within practically any limits without the evenness of the molded article obtained being impaired. Shape-stabilized foam bodies of lower or higher hardness or density can be used in practically any desired ratio of reinforcing fibers
Making foam. According to the method according to the invention, it is also possible, inter alia, to provide for this method, for example, curly hair with higher amounts of elastic binders than was previously possible.



   According to the invention, for example, elastic cushioned bodies can be produced very efficiently and cheaply without any waste and without the elastic cushioned bodies having a tendency to "swim".



   The following example is intended to explain the invention without, however, being restricted thereto.



   Example: In a mold with a size of 90 x 60 x 10 cm that is used for the production of foam bodies, a corresponding shaped piece made of rubber-less curly hair, a so-called rubber hair body, is introduced and the mold is sealed with about 2kg of a polyether-isocyanate reaction mixture foamed. After opening the mold, a shape-stabilized foam body is obtained which does not tend to swim in any way and has a density of about 40 kg / m3.
