Abstract
Przedmiotem zgłoszenia jest uretano-akrylan, który charakteryzuje się tym, że zawiera od 4,5% do 7,9% wag. gliceryny oraz cukrol zawierający w cząsteczce od 4 do 6 atomów węgla oraz pierwszo i drugorzędowe grupy hydroksylowe. Zgłoszenie obejmuje też sposób wytwarzania uretano-akrylanu, który charakteryzuje się tym, że w pierwszym etapie do reaktora wprowadza się składnik izocyjanianowy w ilości od 44 do 58% wag., a następnie dodaje się do niego katalizator w ilości od 0,05 do 0,9% wag., po czym całość miesza się intensywnie, a następnie do mieszaniny reakcyjnej dozuje się mieszaninę gliceryny i cukrolu zawierającego w cząsteczce od 4 do 6 atomów węgla oraz pierwszo- i drugorzędowe grupy hydroksylowe, w ilości od 0,3 do 0,7 mola grup hydroksylowych na 1 mol grup izocyjanianowych składnika izocyjanianowego. Po czym mieszaninę reakcyjną ogrzewa się do temperatury z przedziału 100 do 120°C i intensywnie miesza utrzymując tę temperaturę. Następnie przechodzi się do etapu drugiego, w którym mieszaninę reakcyjną chłodzi się do temperatury z przedziału od 75°C do 85°C i dozuje się akrylan w ilości od 30% do 41% wag., mieszaninę reakcyjną utrzymuje się w temperaturze z przedziału 75°C do 85°C intensywnie mieszając aż do zaniku grup izocyjanianowych.The subject of the application is a urethane acrylate which is characterized in that it contains from 4.5% to 7.9% by weight. glycerins and zucrolol containing from 4 to 6 carbon atoms in the molecule and primary and secondary hydroxyl groups. The application also covers a process for the preparation of urethane acrylate, which is characterized in that in the first step, the isocyanate component is introduced into the reactor in an amount of 44 to 58% by weight, and then the catalyst is added to it in an amount of 0.05 to 0, 9% by weight, and then the whole is mixed intensively, and then a mixture of glycerin and sucrose with 4 to 6 carbon atoms in the molecule and primary and secondary hydroxyl groups in the amount of 0.3 to 0.7 is dosed into the reaction mixture. mole of hydroxyl groups per mole of isocyanate groups of the isocyanate component. The reaction mixture is then heated to a temperature in the range of 100 to 120 ° C and stirred vigorously while maintaining this temperature. It then proceeds to the second stage, in which the reaction mixture is cooled to a temperature in the range of 75 ° C to 85 ° C and acrylate is metered in in an amount of 30% to 41% by weight, the reaction mixture is kept at a temperature in the range of 75 ° C. C to 85 ° C, stirring vigorously until the isocyanate groups are gone.
