Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania kompozycji klejowej, który polega na tym, że umieszcza się w pojemniku podgrzaną do temperatury 50°C żywicę epoksydową niemodyfikowaną, która jest produktem reakcji bisfenolu A z epichlorohydryną o średniej masie cząsteczkowej ≤ 700 o liczbie epoksydowej od 0,480 do 0,510 mol/100 g, w ilości 54,1% wagowo składu kompozycji. Do żywicy epoksydowej niemodyfikowanej dodaje się napełniacz w postaci proszkowanego węglanu wapnia w ilości 2,7% wagowo składu kompozycji po czym miesza się mechanicznie napełniacz z żywicą epoksydową niemodyfikowaną z prędkością 1170 obr./min przez 3 minuty mieszadłem tarczowym dyspergującym z jednoczesnym odpowietrzaniem. Następnie dodaje się utwardzacz poliamidowy o liczbie aminowej od 290 do 360 mg KOH/g w ilości 43,2% wagowo składu kompozycji. Przedmiotem zgłoszenia jest także kompozycja klejowa charakteryzująca się tym, że składa się z żywicy epoksydowej niemodyfikowanej, która jest produktem reakcji bisfenolu A z epichlorohydryną o średniej masie cząsteczkowej ≤ 700 o liczbie epoksydowej od 0,480 do 0,510 mol/100 g w ilości 54,1% wagowo składu kompozycji, napełniacza w postaci proszkowego węglanu wapnia w ilości 2,7% wagowo składu kompozycji oraz utwardzacza poliamidowego o liczbie aminowej od 290 do 360 mg KOH/g w ilości 43,2% wagowo składu kompozycji.The subject of the application is a method of producing an adhesive composition, which consists in placing in a container an unmodified epoxy resin heated to a temperature of 50 ° C, which is a reaction product of bisphenol A with epichlorohydrin with an average molecular weight of ≤ 700 with an epoxy number from 0.480 to 0.510 mol. / 100 g, in an amount of 54.1% by weight of the composition of the composition. To the unmodified epoxy resin, a powdered calcium carbonate filler is added in the amount of 2.7% by weight of the composition, and the filler is mechanically mixed with the unmodified epoxy resin at a speed of 1170 rpm for 3 minutes with a dispersing disk mixer with simultaneous deaeration. A polyamide hardener with an amine number of 290 to 360 mg KOH / g is then added in an amount of 43.2% by weight of the composition. The subject of the application is also an adhesive composition characterized in that it consists of an unmodified epoxy resin, which is a reaction product of bisphenol A with epichlorohydrin with an average molecular weight of ≤ 700 with an epoxy number from 0.480 to 0.510 mol / 100 g in the amount of 54.1% by weight of the composition of the composition, a powdered calcium carbonate filler in an amount of 2.7% by weight of the composition and a polyamide hardener with an amine number from 290 to 360 mg KOH / g in an amount of 43.2% by weight of the composition.
