Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania transferowej taśmy samoprzylepnej, o grubości od 200 do 2000 g/m2 z wykorzystaniem fotoreaktywnej bezrozpuszczalnikowej kompozycji kleju samoprzylepnego na bazie akrylanów, powleczenia na nośniki sieciowania. Sposób ten charakteryzuje się tym, że homogenizuje się 50 - 80% wagowych polimeru fotoreaktywnego kleju rozpuszczalnikowego, 10 - 40% wagowych fotoreaktywnego rozcieńczalnika na bazie uretano(met)akrylanów, 5 - 15% wagowych fotoreaktywnej żywicy proadhezyjnej, 0,5 - 5% wagowych fotoreaktywnego związku sieciującego rodnikowo w postaci wielofunkcyjnych monomerów (met)akrylanowych, 0,5 - 3% wagowych fotoreaktywnego związku sieciującego kationowo w postaci wielofunkcyjnych eterów winylowych oraz wielofunkcyjnych epoksydów, 0,1 - 5% wagowych fotoinicjatora rodnikowego I rodzaju oraz 0,1 - 3% wagowych fotoinicjatora kationowego. Suma wszystkich komponentów wchodzących w skład fotoreaktywnej kompozycji samoprzylepnej wynosi 100%. Następnie oddestylowuje się próżniowo medium polimeryzacyjne z fotoreaktywnej kompozycji, otrzymując samoprzylepną kompozycję bezrozpuszczalnikową o lepkości umożliwiającej jej powlekanie w temperaturze pokojowej, po czym kompozycję powleka się na silikonowaną folię poliestrową (transparentną dla promieniowania UV) i zabezpiecza z drugiej strony silikonowaną folię poliestrową. Tak zabezpieczoną kompozycję poddaje się sieciowaniu obustronnie pod lampami UV. Najpierw sieciuje się kompozycję pod lampą UV-A w zakresie 415-400 nm, a następnie pod lampą UV-C w zakresie 215 - 285 nm. W wyniku sieciowania otrzymuje się transferową taśmę samoprzylepną w postaci filmu klejowego, zabezpieczonego obustronnie silikonowaną folią poliestrową. W sposobie fotoreaktywny klej rozpuszczalnikowy otrzymuje się na drodze polimeryzacji rodnikowej, w medium polimeryzacyjnym- octanie etylu, w obecności 0,1% wagowych inicjatora AIBN, od 90,2 do 96% wagowych alkilowego akrylanu, od 3,5 do 8% wagowych kwasu akrylowego i od 0,4 do 1,8% wagowych nienasyconego fotoinicjatora. Jako fotoreaktywną żywicę proadhezyjną w kompozycji stosuje się żywicę na bazie poli(akrylanu butylu), poli(akrylanu 2-etyloheksylu), poli(akrylanu decylu) lub poli(akrylanu dodecylu).The subject of the application is a method for the production of a transfer pressure-sensitive adhesive tape with a thickness of 200 to 2000 g / m2 using a photoreactive solvent-free acrylic-based pressure-sensitive adhesive composition, a coating for cross-linking carriers. The method is characterized by homogenizing 50 - 80% by weight of the polymer of the photoreactive solvent adhesive, 10 - 40% by weight of the photoreactive diluent based on urethane (meth) acrylates, 5 - 15% by weight of the photoreactive pro-adhesive resin, 0.5 - 5% by weight photoreactive radical cross-linking compound in the form of polyfunctional (meth) acrylate monomers, 0.5 - 3% by weight of photoreactive cationic cross-linking compound in the form of polyfunctional vinyl ethers and polyfunctional epoxides, 0.1 - 5% by weight of type I radical photoinitiator and 0.1 - 3 % by weight of a cationic photoinitiator. The sum of all components included in the photoreactive self-adhesive composition is 100%. Then, the polymerization medium is vacuum distilled from the photoreactive composition, obtaining a solvent-free self-adhesive composition with a viscosity that allows it to be coated at room temperature, after which the composition is coated on a siliconized polyester film (transparent to UV radiation) and on the other side secured with a siliconized polyester film. The composition secured in this way is cross-linked on both sides under UV lamps. First, the composition is crosslinked under a UV-A lamp in the range of 415-400 nm, and then under a UV-C lamp in the range of 215-285 nm. As a result of cross-linking, a self-adhesive transfer tape is obtained in the form of an adhesive film, secured on both sides with a siliconized polyester film. In the process, a photoreactive solvent adhesive is obtained by radical polymerization, in the polymerization medium - ethyl acetate, in the presence of 0.1% by weight of AIBN initiator, from 90.2 to 96% by weight of an alkyl acrylate, from 3.5 to 8% by weight of acrylic acid and from 0.4 to 1.8% by weight of an unsaturated photoinitiator. A resin based on poly (butyl acrylate), poly (2-ethylhexyl acrylate), poly (decyl acrylate) or poly (dodecyl acrylate) is used as the photoreactive adhesive in the composition.
