Abstract
Zgodny z wynalazkiem sposób charakteryzuję się tym, że z umieszczonego pomiędzy dwoma obracającymi się przeciwbieżnie wałkami (1, 2) zasobnika z klejem (8) pobiera się mieszankę kleju poliuretanowego i nanododatku w postaci komponentu na bazie cząsteczek srebra, o stężeniu srebra wynoszącym około 10% na nośniku krzemionkowym. Mieszankę tę za pomocą wstępnie ustalających gramaturę warstwy kleju wałków (2) oraz (3) nanosi się równomiernie na wstęgę lekko podgrzanej folii nośnej (2) o grubości od 12 do 20 µm, cienką warstwą w ilości około 2,0 - 2,5 g/m<sup>2</sup> folii, a następnie folię (9) z tak naniesioną warstwą kleju kieruje się pomiędzy wałek (3) i gumowany wałek (4), za pomocą których dokładnie ustala się gramaturę warstwy kleju z nanododatkiem, tak, by wynosiła ona od 0,0202 do 0,0566 g/m<sup>2</sup> laminatu, po czym folię nośną (9) podaje się ją na trójrolkowy układ laminujący (5, 6 i 7), gdzie pomiędzy bębnem (5) i rolką (6) skleja się ją z dolotową (dolaminowywaną) folią (10), którą podaje się pomiędzy bęben (5) i rolkę (6) za pośrednictwem wałków (12). Folia nośna (9) jest folią polipropylenową o symbolu PP dwuosiowo-orientowaną zbudowaną z merów o wzorze [CH<sub>2</sub>CH(CH<sub>3</sub>)] składającą się z polipropylenu w ilości 91 - 94% wag., koncentratów antyblokingowych w ilości 1 - 2% wag., koncentratów poślizgowo-antystatycznych w ilości 1 - 3% wag., koncentratów zmętniających i bieli tytanowej w ilości 0,5 - 1% wag. oraz węglanu wapnia w ilości 1 - 3% wag., natomiast folia dolotowa (10) jest folią poliestrową BOPET (C<sub>10</sub>H<sub>8</sub>0<sub>4</sub>)<sub>n</sub> dwuosiowo-orientowaną o grubości 12 µm do 30 µm. Po sklejeniu tych warstw otrzymuje się giętki laminat (11).The method according to the invention is characterized by the fact that a mixture of polyurethane glue and a nano-additive in the form of a component based on silver particles, with a silver concentration of about 10%, is taken from the glue container (8) arranged between two counter-rotating rollers (1, 2). on a silica support. This mixture, by means of pre-setting the basis weight of the adhesive layer, rollers (2) and (3) is evenly applied to the web of slightly heated carrier foil (2) with a thickness of 12 to 20 µm, in a thin layer in the amount of about 2.0 - 2.5 g / m <sup> 2 </sup> of the foil, and then the foil (9) with the adhesive layer applied in this way is directed between the roller (3) and the rubberized roller (4), by means of which the basis weight of the adhesive layer with nano-additive is precisely determined, yes to be from 0.0202 to 0.0566 g / m <sup> 2 </sup> of the laminate, then the carrier foil (9) is fed to the three-roll laminating system (5, 6 and 7), where between the drum (5) and the roller (6) are glued to the inlet (laminated) foil (10), which is fed between the drum (5) and the roller (6) by means of rollers (12). The carrier film (9) is a polypropylene film with the symbol PP biaxially oriented, composed of units of the formula [CH <sub> 2 </sub> CH (CH <sub> 3 </sub>)] consisting of polypropylene in the amount of 91 - 94% by weight, anti-block concentrates in the amount of 1 - 2% by weight, slip-antistatic concentrates in the amount of 1 - 3% by weight, opacifying concentrates and titanium white in the amount of 0.5 - 1% by weight. and calcium carbonate in an amount of 1 - 3 wt.%, while the inlet film (10) is a BOPET polyester film (C <sub> 10 </sub> H <sub> 8 </sub> 0 <sub> 4 </sub> ) <sub> n </sub> biaxially oriented with a thickness of 12 µm to 30 µm. After gluing these layers, a flexible laminate (11) is obtained.
