Description
Verfahren zum gegenseitigen Verkleben von Flächen Bekannt ist, bei Verklebung glatter, nicht poröser Flächen, wie z.B. Metallflächen mit Metallflächen oder Metallflächen mit Kunststofflächen oder Kunststofflächen mit Kunststofflächen (es kommen auch Glasflächen infrage) oder bei Verklebung solcher Plächen mit porösen Flächen, wie s.B, Metallflächen mit Holzilächen, in die Klebefuge (Klebespalt) gewebte Textilmaterialien, wie etwa Mullbinden aus Baumwolle, einzulegen, damit verhütet wird,-dass beim nachfolgenden Pressen und Härten der Klebstoff aus der klebefuge wieder herausgepresst und die Bildung eines ausreichenden Klebefilmes dadurch verhindert oder die Festigkeit der Klebung beeinträchtigt wird.Method for mutual gluing of surfaces is known at Bonding of smooth, non-porous surfaces, e.g. metal surfaces with metal surfaces or metal surfaces with plastic surfaces or plastic surfaces with plastic surfaces (glass surfaces are also possible) or when such surfaces are glued with porous ones Surfaces, such as s.B, metal surfaces with wooden surfaces, woven into the glue joint (glue gap) Inserting textile materials such as cotton gauze bandages to prevent them becomes, -that during the subsequent pressing and hardening of the adhesive from the adhesive joint pressed out again and thus prevents the formation of a sufficient adhesive film or the strength of the bond is impaired.
Ein Nachteil bei der Verwendung von Geweben ist, daes die Verteilung des flebstoffes im Gewebe ungleichmäßig ist, da im Bereiche der Gewebemaschen (gemeint sind Löcher des Gewebegitters) jeweils eine Klebstoff anhäufung, an den Kreuzungsstellen von Schuß und Kette jeweils eine Klebstoffverarmung eintreten. Dies führt dazu, dass nur eine rasterartige Verklebung (punktueller Natur) eintritt. A disadvantage of using tissues is that it is spread out of the fabric in the fabric is uneven, because in the area of the fabric mesh (meant are holes in the mesh) each have an adhesive accumulation, a depletion of glue occurs at the crossing points of weft and warp. This leads to the fact that only a grid-like bonding (of a punctiform nature) occurs.
Darüberhinaus besteht die Gefahr, dass die Klebetagen bei Verwendung von Geweben aus natürlichen Fasern bei Einwirkung von Feuchtigkeit durch diese unterwandert werden und dass so die Festigkeit bzw. Dauerhaftigkeit der Verklebung leidet. In addition, there is a risk that the adhesive days when used of tissues made of natural fibers infiltrated by them when exposed to moisture and that the strength or durability of the bond suffers.
Erfindungsgemä# wird so verfahren, dass an die Stelle des bislang verwandten Gewebes ein nicht gewebtes"'asermaterial, sei es mit parallelisierten oder wirren Fasern, gesetzt wird. According to the invention, the procedure is that in place of the previously related tissue a non-woven "'asermaterial, be it with parallelized or tangled fibers.
Durch erfindungsgemäße Einlagerung eines nichtgewebten Materials, z.B. eines Vliesstoffes in die Klebefuge findet eine wesentliche Erhöhung des wirksamen Aflteils des Kleostoffes sowie eine gleichmä#igere Verteilung des Klebstoffes in der Klebefuge statt. Bei den nichtgewebten Materialien handelt es sich z.B. um Vliesstoffe aus z. 3. Polyester-, Polyaaiid- oder Polyacrylnitril-Fasern. Erfindungsgemäß ist es vorteilhaft, solche Vliesstoffe oder dergleichen zu verwenden, die zuvor etwa auf einer Nadelmaschine durch entsprechende Nadelung verfestigt aind, wobei also ein ausreichender Zusammenhang zwischen den Fasern des Vlieses geschaffen ist. Andererbereits oder auch zusätzlich kann der Gedanke der Erfindung angewandt werden, die ausieichende Verfestigung des Vliesstoffes bzw. der Fasern des Vlieses durch besondere Bindemittel (z.B. durch leichte Tränkung mit solchen Bindemitteln, die sich sowohl mit dem Fasermaterial als auch mit dem Klebstoffmaterial vertragen bzw. sogar die klebung bzw. die Klebkraft fördern) zu versehen. By incorporating a non-woven material according to the invention, E.g. a nonwoven fabric in the glue line finds a significant increase in the effective Aflpart of the adhesive as well as a more even distribution of the adhesive in the glue line instead. The non-woven materials are, for example, non-woven fabrics from z. 3. Polyester, polyamide or polyacrylonitrile fibers. Is according to the invention it is advantageous to use such nonwovens or the like, previously about solidified on a needling machine by appropriate needling, so where a sufficient connection between the fibers of the fleece is created. Others already or in addition, the concept of the invention can be applied, the sufficient Solidification of the nonwoven or the fibers of the nonwoven by special binders (e.g. by lightly impregnating with such binders, which are both with the fiber material as well as tolerated with the adhesive material or even the glue or promote the adhesive strength).
Solche Fasern bzw. Vliese weisen den Vorteil auf, dass sie keine oder wenig Feuchtigkeit aufnehmen; ausserdem ist die Hitzebeständigkeit solcher Fasern größer als die natürlicher Fasern. Such fibers or nonwovens have the advantage that they do not or absorb little moisture; in addition, the heat resistance is such Fibers larger than natural fibers.
Die Verwendung natrlicher Fasern für den Vliesstoff schließt aber die Erfindung nicht aus, obwohl in vielen ällen die genannten Kunststoffasern vorzuziehen sind. However, the use of natural fibers for the nonwoven does not apply the invention does not stop, although in many cases the synthetic fibers mentioned are preferable are.
Als weiterer Vorteil kommt hinzu, dass bei Verwendung des beschriebenen Vliesstoffes an Stelle von Klebefilmen streich- oder spritzfähige Klebestoffe eingesetzt werden können; dies bedeutet reine einfachere Arbeitsweise. Another advantage is that when using the described Nonwovens are used instead of adhesive films that can be brushed or sprayed on can be; this means pure simpler way of working.
Die Verwendung eines Vliesstoffes ergibt Klebefugen oder -spalten mit größerer Elastizität als ohne Vliesstoff. The use of a non-woven fabric results in glue joints or gaps with greater elasticity than without nonwoven.
Beispiel: Aus Polyester-Fasern wird auf pneumatischem Wege oder durch Kreuzlegung ein Faservlies von ca. 80 gr/qm hergestellt und einem Nadelvorgang unterzogen. Dieses Nadelvlies wird auf eine etallfläche, die vorher mit einem geeigneten Klebstoff, z.B. Phenol- oder thoxlinharz, welches mit Härter versetzt wurde, bestrichen wurde, aufgelegt, angedrückt, und die zweite, ebenfalls mit Klebstoff bestrichene Fläche (z.B. Kunststoff oder Holz) aufgelegt. Abschließend wird je nach den Verarbeitungsbedingungen des Klebstoffes unter Druck heiß oder kalt ausgehärtet. Eine solche Verklebung weist gute Scherfestigkeiten auf, während eine Verklebung gleicher Materialien, aber ohne Vlies in der Klebefuge wesentlich geringere Scherfestigkeiten aufweist. Example: Polyester fibers are pneumatically or through Cross-laying a fiber fleece of approx. 80 gr / sqm is made and subjected to a needling process. This needled fleece is placed on a metal surface that has been previously treated with a suitable adhesive, e.g. phenolic or thoxlin resin to which hardener has been added, has been coated, placed on top, pressed down, and the second surface, also coated with adhesive (e.g. plastic or wood). Finally, depending on the processing conditions of the adhesive cured hot or cold under pressure. Such a bond has good shear strengths, while bonding the same materials, however without Fleece in the adhesive joint has significantly lower shear strengths.
Der'urundgedanke der Erfindung ist auch dann erfüllt, wenn der Klebstoff auch in anderer Weise als durch Aufspritzen oder Aufstreichen auf die Flächen aufgebracht wird; es kann beispielsweise der Klebstoff in Form von bekannten Klebefolien, die entsprechend zugeschnitten werden können, auf die Flächen aufgelegt oder aufgeheftet werden, wobei dann in der schon beschriebenen Weise ein Vlies zwischengelegt wird und worauf dann wiederum in der beschriebenen Weise der Klebevorgang mit oder ohne Wärmezufuhr, bei Folien allerdings mit Wärmezufuhr erfolgt. The basic concept of the invention is also fulfilled when the adhesive also applied in other ways than by spraying or brushing onto the surfaces will; it can, for example, the adhesive in the form of known adhesive films, the can be cut accordingly, placed on the surfaces or stapled be, a fleece is then interposed in the manner already described and then again in the manner described, the gluing process with or without Heat supply, but with foils with heat supply.
Die Zeichnung zeigt einige Beispiele und zwar Fig. 1 im Schnitt eine einfache Überlappungsklebung Fig. 2 eine einfache Laschenüberklebung, Fig. 3 eine totale Flächenverklebung, Fig. 4 einen vergrößerten Schnitt, der zu den genannten Fig. 1 bis 3 korrespondiert. The drawing shows some examples, namely FIG. 1 in section simple overlap gluing, FIG. 2 a simple overlap gluing, FIG. 3 a total surface bonding, FIG. 4 shows an enlarged section that corresponds to the aforementioned 1 to 3 correspond.
Gemäß Fig. 1 überlappen sich die beiden Werkstücke 1 und 2, die zu verklebende Flächen 1 und 2' im aber lappungsbereich besitzen. Die Werkstoffe, aus denen die Werkstücke 1 und 2 bestehen können, sind weiter oben bereits angegeben. Es kann sich beispielsweise um ein getallblech 1 und ein Kunststoffelement 2 handeln. Die Klebefuge oder der Klebespalt 3 enthält das im Uberlappungsbereich zwischengelegte Faservlies, das der Deutlichkeit halber nur in Fig. 4 gezeigt ist. Die Flächen 1' und 2' werden alao bei diesem Klebevorgang beispielsweise mit Klebstoff bestrichen, und zwar sind hierbei die Werkstücke 1 und 2 noch räumlich voneinander getrennt. Dann wird das Vlies auf eine der beiden flächen 1' oder 2' aufgelegt, nachdem es zuvor entsprechend zugeschnitten war; alsdann werden die Werkstücke 1,2 in die in Fig. 1 gezeigte gegenseitige Uberlappungslage gebraoht und es wird gegebenenfalls durch Pressung im Sinne der Pfeile 4,5 die Verbindung fertiggestellt, gegebenenfalls unter Wärmezufuhr. According to FIG. 1, the two workpieces 1 and 2, which are to overlap but have adhesive surfaces 1 and 2 'in the lap area. The materials, made of which the workpieces 1 and 2 can exist are already specified above. It can be a metal sheet 1 and a plastic element 2, for example. The adhesive joint or the adhesive gap 3 contains the interposed in the overlap area Fiber fleece, which is only shown in FIG. 4 for the sake of clarity. The surfaces 1' and 2 'are coated with glue, for example, during this gluing process, namely, the workpieces 1 and 2 are still spatially separated from one another. Then the fleece is placed on one of the two surfaces 1 'or 2' after it was previously tailored accordingly; then the workpieces 1,2 are in the in Fig. 1 shown mutual overlap layer and it is optionally the connection is completed by pressing in the direction of the arrows 4, 5, if necessary with the addition of heat.
Ganz analog wird gemäß Fig. 2 vorgegangen. Es handelt sich hier beispielsweise um zwei Holzelemente 21,22, die in gleicher Ebene liegen und durch eine einfache Metallasche 26 verbunden werden sollen. (Selbstverständlich kann eine spiegelbildlich angeortnete weitere Metallasche vorgesehen werden). Auch hier werden die Flächen 21', 22' und 26' mit Klebstoff versehen und alsdann wird in dem Klebspalt 23 das Vlies vorhanden sein; die übrigen Arbeitsvorgänge sind entsprechend dem, was zu Fig. 1 gesagt wurde. The procedure according to FIG. 2 is completely analogous. It is here for example around two wooden elements 21,22, which are in the same plane and through a simple one Metal tab 26 are to be connected. (Of course, one can be a mirror image arranged further metal tabs can be provided). Here, too, the surfaces 21 ', 22' and 26 'are provided with adhesive and then in the adhesive gap 23 the Fleece be present; the rest of the operations are according to what is to be Fig. 1 was said.
Gemäß Fig. 3 lassen sich auch größere Flächen miteinander verbinden; hier sind die flachen Werkstücke 31,32 wiederum unter Zwischenlegen eines Vlieses in die Klebefuge 33 in korrespondierender Weise miteinander verbunden. According to FIG. 3, larger areas can also be connected to one another; here the flat workpieces 31, 32 are again with a fleece in between connected to one another in a corresponding manner in the adhesive joint 33.
Es lassen sich noch viele weitere Varianten im Rahmen der Erfindung denken. So können auch beispielsweise gekrümmte Flächen miteinander verbunden werden; es kann mehrfache Uberlappung gewählt werden. Es können schicht- oder paketweise viele Werkstücke miteinander vereinigt werden. There are many other variants within the scope of the invention think. For example, curved surfaces can also be connected to one another; multiple overlap can be chosen. It can layer- or many workpieces can be combined with one another in packets.
Fig. 4 zeigt deutlicher eine Klebestelle. Auf den Flächen 1 und 2' haften, in der Darstellung nicht mehr sichtbar, Klebstoffschichten, wobei der Klebstoff sich innig mit dem Faservlies 7 vermischt hat. Tatsächlich ist in der Praxis das Faservlies 7 sehr stark zusammengedrückt in verklebtem Zustand also nur noch hauchdünn (etwa papierdUnn). Fig. 4 shows a glue point more clearly. On surfaces 1 and 2 ' Adhere, no longer visible in the illustration, adhesive layers, whereby the adhesive has mixed intimately with the nonwoven fabric 7. In fact, in practice it is Fiber fleece 7 is very strongly compressed in the bonded state, so it is only very thin (about paper thin).
Die Flächen 1', 2', also die miteinander zu verklebenden Werkstückflächen brauchen nicht aufgerauht, sondern nur gesäubert zu sein. Bislang war das Aufrauhen häufig als unumgänglich angesehen worden; selbstverständlich kann aber auch bei Anwendung der Erfindung zußätzlich aufgerauht werden. The surfaces 1 ', 2', that is to say the workpiece surfaces to be glued together do not need to be roughened, just cleaned. So far it was roughening often seen as inevitable; but of course it can also be at Application of the invention are additionally roughened.
