Description
Grundierschicht zur Haftverbesserung von druckempfindlichen Haftklebern auf hydrophilen und hydrophoben Trägern von Klebefolien, -bändern u. dgl. Primer layer to improve the adhesion of pressure-sensitive adhesives on hydrophilic and hydrophobic substrates of adhesive films, tapes and the like.
Die Erfindung betrifft eine Grundierschicht zum Verankern von üblichen, klebrigen und druckempfindlichen Haftklebern auf hydrophilen und hydrophoben Trägern, wie sie bei der Herstellung von Haftklebebändern, -folien u. dgl. verwendet werden. Bei Haftklebebändern muß der Haftkleber fest am Träger verankert sein, da er sich sonst ablösen könnte, wenn das Haftklebeband von der Rolle abgewickelt wird. Eine solche Verankerung kann, wie man weiß, durch eine Zwischenschicht (Grundstrich) zwischen Trägerfolie und der Klebstoffschicht erzielt werden. The invention relates to a primer layer for anchoring conventional, sticky and pressure-sensitive adhesives on hydrophilic and hydrophobic substrates, as used in the manufacture of pressure-sensitive adhesive tapes, films and the like. In the case of pressure-sensitive adhesive tapes, the pressure-sensitive adhesive must be firmly anchored to the carrier because it is otherwise it could peel off when the pressure-sensitive adhesive tape is unwound from the roll. One such anchoring can, as we know, through an intermediate layer (base line) can be achieved between the carrier film and the adhesive layer.
Viele der bekannten Grundstriche (Zwischenschichten) bestehen aus zwei Phasen. Ein Grundstrich für einen hydrophilen Träger (Cellulosefilm) besteht z. B. aus einer Mischung von Kautschuklatex und einem hydrophilen Material, wie Kasein, Polyvinylalkohol od. dgl. Die geschlossene hydrophile, kolloide Klebstoffphase bewirkt eine feste Bindung zu der hydrophilen Celluloseoberfläche; die disperse Kautschukphase bindet die in organischer Lösung aufgetragene druckempfindliche Klebstoffschicht. Der Grundstrich haftet so einerseits fest an der druckempfindlichen Haftklebschicht und andererseits an dem Trägerfilm. Die Adhäsion des druckempfindlichen Klebstoffilmes zur Trägerfolie ist jetzt größer als zu der Oberfläche irgendeines anderen Materials. Many of the well-known basic strokes (intermediate layers) consist of two phases. There is a base coat for a hydrophilic carrier (cellulose film) z. B. from a mixture of rubber latex and a hydrophilic material, such as Casein, polyvinyl alcohol or the like. The closed hydrophilic, colloidal adhesive phase causes a firm bond to the hydrophilic cellulose surface; the disperse The rubber phase binds the pressure-sensitive adhesive layer applied in organic solution. On the one hand, the base coat thus adheres firmly to the pressure-sensitive pressure-sensitive adhesive layer and on the other hand on the carrier film. The adhesion of the pressure sensitive adhesive film to the carrier film is now larger than to the surface of any other material.
Dadurch kann ein Ablösen der druckempfindlichen Klebeschicht von dem Träger z. B. beim Abwickeln des Klebebandes von der Rolle ausgeschaltet werden.This can cause the pressure-sensitive adhesive layer to peel off Carrier z. B. be switched off when unwinding the tape from the roll.
Gegenstand der Erfindung ist ein neuer Grundstrich für Klebefolien und -bänder mit verbesserter Verankerung des druckempfindlichen Klebstoffes sowohl an hydrophilen als auch an hydrophoben Trägern. Der neue Grundstrich wird gelöst in einem Lösungsmittel angewendet. Er ist klar, farblos und kann nach jedem der üblichen Verfahren, z. B. mittels Spritzdüsen, Luftrakel oder durch Walzenauftragsmaschinen, auf den Träger aufgebracht werden. The invention relates to a new base coat for adhesive films and tapes with improved anchoring of the pressure sensitive adhesive both on hydrophilic as well as on hydrophobic carriers. The new stem is solved applied in a solvent. It is clear, colorless and can look like any of the usual procedures, e.g. B. by means of spray nozzles, air knives or roller application machines, be applied to the carrier.
Die Grundierschicht wird vorzugsweise in sehr dünner Schicht von etwa 0,:S bis 8,0 g/m2 Feststoffgehalt aufgetragen. Dünnere Grundierschichten eignen sich für Kunststoffolien, dickere für gewebte oder nichtgewebte faserige Träger. Ein druckempfindlicher Klebstoff wird auf die mit der Grundierung versehenen Träger zu einem trockenen Belag aufgetragen. Die Auftragsmenge des druckempfindlichen Klebstoffes ist abhängig vom Trägermaterial, von der Art der Verwendung des Haftklebebandes, und kann 10 bis 200 g/m² Feststoffgehalt betragen. The primer coat is preferably in a very thin layer of about 0.: S to 8.0 g / m2 solids content applied. Thinner primer coats are suitable Opt for plastic sheeting, thicker ones for woven or non-woven fibrous carriers. A pressure sensitive adhesive is applied to the primed backing applied to a dry surface. The amount of pressure sensitive adhesive applied depends on the carrier material, on the type of use of the adhesive tape, and can be 10 to 200 g / m² solids content.
Die Grundierschicht gemäß der Erfindung besteht a) aus Polyamidharzen, die durch Kondensation von di- oder trimerisierten ungesättigten Fettsäuren (vornehmlich Linolsäure) mit Polyaminen nach dem allgemeinen Schema n HOOCRCOOH $nH2N-R'-NH2 vHO (OCRCONHR'NH) nH hergestellt werden, b) mindestens einem oder mehreren abgebauten Elastomeren und c) organischen Lösungsmitteln. The primer layer according to the invention consists of a) polyamide resins, those caused by the condensation of dimerized or trimerized unsaturated fatty acids (primarily Linoleic acid) with polyamines according to the general scheme n HOOCRCOOH $ nH2N-R'-NH2 vHO (OCRCONHR'NH) nH are produced, b) at least one or more degraded Elastomers and c) organic solvents.
Rohkautschuk ist z. B. ein geeignetes Elastomeres, das so lange auf der Walze abgebaut werden muß, bis es in einem organischen Lösungsmittel, wie Isopropylalkohol, Toluol und Benzin, eine fließende Lösung ergibt. Raw rubber is z. B. a suitable elastomer that lasts for so long the roller must be dismantled until it is in an organic solvent, such as isopropyl alcohol, Toluene and gasoline, results in a flowing solution.
Bespiel Die Polyamidharze werden in Isopropanol-Toluol 1:1 unter Rühren gelöst. Der abgebaute, in Benzin gelöste Kautschuk wird unter Rühren der Polyamidharzlösung zugesetzt. Die Kautschuklösung muß eine dünne Lösung sein und darf 1001o Feststoffgehalt nicht übersteigen. Example The polyamide resins are in isopropanol-toluene 1: 1 under Stirring dissolved. The degraded rubber dissolved in gasoline is stirred into the Polyamide resin solution added. The rubber cement must be a thin solution and must not exceed 1001o solids content.
Zur Herstellung von verbesserten Klebefolien und -bändern mit hydrophoben oder hydrophilen Trägern, insbesondere auf der Basis von Kunststoffilmen, Papieren und Geweben, wird ein Grundstrich folgender Zusammensetzung verwendet: Polyamidharz Schmelzpunkt 100 bis 1100 C 15 Gewichtsteile Viskosität bei 1500C (gemessen in Brookfield-Viskosimeter) .......................... 15 bis 30 Poise Polyamidharz Schmelzpunkt 43 bis 53°C 35 Gewichtsteile Viskosität bei 1500C (gemessen in Brookfield-Viskosimeter) .......................... 10 bis 15 Poise Kautschuk ....................... 5 Gewichtsteile Isopropylalkohol................ 100 Gewichtsteile Toluol ........................... 200 Gewichtsteile Benzin Sdp. 80 bis 110°C .............. 200 Gewichtsteile Sdp. 100 bis 1400 .............. 300 Gewichtsteile Verschiedene Polyamidharze von fester bis halbfester bis zu flüssiger Konsistenz sind im Handel erhältlich und können je nach der Beschaffenheit des druckempfindlichen Klebstoffes untereinander abgestimmt und gemischt werden. For the production of improved adhesive films and tapes with hydrophobic or hydrophilic carriers, in particular based on plastic films, papers and fabrics, a base coat of the following composition is used: polyamide resin Melting point 100 to 1100 C 15 parts by weight viscosity at 1500 C (measured in Brookfield viscometer) .......................... 15 to 30 poise Polyamide resin melting point 43 to 53 ° C 35 parts by weight viscosity at 1500C (measured in Brookfield viscometer) .......................... 10 to 15 poise rubber ................... .... 5 parts by weight Isopropyl alcohol ................ 100 parts by weight toluene ........................... 200 parts by weight gasoline b.p. 80 to 110 ° C .............. 200 parts by weight b.p. 100 to 1400 .............. 300 parts by weight Various polyamide resins of solid to semi-solid to liquid consistency are commercially available and can coordinated with one another depending on the nature of the pressure-sensitive adhesive and be mixed.
