Abstract
Przedmiotem zgłoszenia jest kompozycja klejowa, która charakteryzuje się tym, że składa się z żywicy epoksydowej, będącej produktem reakcji bisfenolu A, epichlorohydryny oraz rozcieńczalnika z nasyconej żywicy poliestrowej, o średniej masie cząsteczkowej ≤ 700 i liczbie epoksydowej ≥ 0,40 mol/100 g w ilości 80% wagowo składu kompozycji, utwardzacza aminowego aminy alifatycznej o liczbie aminowej co najmniej 1100 mg KOH/g w ilości 8% wagowo składu kompozycji oraz napełniacza w postaci węgla amorficznego o gęstości nasypowej 20 - 200 kg/m<sup>3</sup> w ilości 12% wagowo składu kompozycji. Zgłoszenie zawiera także sposób wytwarzania kompozycji klejowej, który polega na tym, że do pojemnika z podgrzaną do temperatury 50 C żywicą epoksydową, będącą produktem reakcji bisfenolu A, epichlorohydryny oraz rozcieńczalnika z nasyconej żywicy poliestrowej, o średniej masie cząsteczkowej ≤ 700 i liczbie epoksydowej ≥ 0,40 mol/100 g w ilości 80% wagowo składu kompozycji dodaje się napełniacz w postaci węgla amorficznego o gęstości nasypowej 20 - 200 kg/m<sup>3</sup> w ilości 12% wagowo składu kompozycji, po czym miesza się żywicę epoksydową z napełniaczem z prędkością obrotową 1170 obr./min przez 2 minuty mieszadłem turbinowym tarczowym z zębami trapezowymi z jednoczesnym odpowietrzaniem w temperaturze 23 C i przy wilgotności powietrza 26%. Następnie po wymieszaniu żywicy epoksydowej z napełniaczem dodaje się utwardzacz aminowy aminy alifatycznej o liczbie aminowej co najmniej 1100 mg KOH/g w ilości 8% wagowo składu kompozycji, po czym miesza się całość z prędkością obrotową 1170 obr./min przez 2 minuty mieszadłem turbinowym tarczowym z zębami trapezowymi z jednoczesnym odpowietrzaniem w temperaturze 23 C i przy wilgotności powietrza 26%. Następnie całość utwardza się przez 7 dni w temperaturze 23 C i przy wilgotności powietrza 26%.The subject of the application is an adhesive composition, which is characterized by the fact that it consists of an epoxy resin, which is a reaction product of bisphenol A, epichlorohydrin and a saturated polyester resin diluent, with an average molecular weight ≤ 700 and an epoxy number ≥ 0.40 mol/100 g in the amount 80% by weight of the composition, an aliphatic amine hardener with an amine number of at least 1100 mg KOH/g in an amount of 8% by weight of the composition and amorphous carbon filler with a bulk density of 20 - 200 kg/m<sup>3</sup> in an amount of 12% by weight of the composition. The application also includes a method of producing an adhesive composition, which consists in filling a container with an epoxy resin, heated to a temperature of 50°C, which is a reaction product of bisphenol A, epichlorohydrin and a saturated polyester resin diluent, with an average molecular weight ≤ 700 and an epoxy number ≥ 0 .40 mol/100 g in the amount of 80% by weight of the composition, a filler in the form of amorphous carbon with a bulk density of 20 - 200 kg/m<sup>3</sup> is added in the amount of 12% by weight of the composition, and then the epoxy resin is mixed with a filler at a rotational speed of 1170 rpm for 2 minutes with a disk turbine agitator with trapezoidal teeth with simultaneous de-aeration at a temperature of 23 C and air humidity of 26%. Then, after mixing the epoxy resin with the filler, an aliphatic amine amine hardener with an amine value of at least 1100 mg KOH/g is added in the amount of 8% by weight of the composition, and then the whole thing is mixed at a rotational speed of 1170 rpm for 2 minutes with a disk turbine mixer and trapezoidal teeth with simultaneous venting at 23°C and 26% air humidity. Then the whole is cured for 7 days at 23°C and 26% humidity.
