Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania bezformaldehydowej żywicy melaminowej, który polega na tym, że 15 - 20 części wagowych melaminy, 30 - 45 części wagowych glioksalu 11 - 13 części wagowych dimetoksyacetaldehydu, 8 - 14 części wagowych wody oraz 7 - 9 części wagowych wodnego roztworu kwasu nieorganicznego o stężeniu 15 - 25%, miesza się w temperaturze 40 – 75°C przez 30 - 50 minut, pozostawia się na 30 - 50 minut, po czym w drugim etapie, dodaje się 10 - 15 części wagowych wodnego roztworu kwasu nieorganicznego o stężeniu 15 - 25%, miesza się w temperaturze 40 – 75°C przez 30 - 50 minut i pozostawia się na 30 - 50 minut.
