Abstract
Inventia se refera la un procedeu de obtinere a hîrtiei decorative stratificate (HDS) cu propagare lenta a flacarii, folosita la constructia mijloacelor de transport (nave, vagoane de cale ferata, tramvaie, autobuze etc.), precum si la fabricarea mobilierului, în special a celui de bucatarie. Procedeul consta în presarea la temperatura de 135...165 degree C a 2...8 filme ureice dintr-o hîrtie fenolica (absorbanta) cu gramajul de 80...180 g/m2 care se impregneaza în rasina ureoformaldehidica continînd 30...50% rasina uscata si avînd un raport molar cuprins între 3,5:1,5:1,0 si 3,0:1,0:0,5 (formaldehida:uree:melamina), presarea facîndu-se împreuna cu un film bariera melaminic si un film decor melaminic cunoscute.The invention relates to a process for obtaining the decorative laminated paper (HDS) with slow propagation of the flame, used for the construction of the means of transport (ships, railway wagons, trams, buses, etc.), as well as for the manufacture of furniture, in particular of the kitchen. The process consists in pressing, at a temperature of 135 ... 165 ° C, of 2 ... 8 ureic films of a phenolic paper (absorbent) with a weight of 80 ... 180 g / m2 which is impregnated in the urea formaldehyde resin containing 30. 50% dry resin and having a molar ratio of between 3.5: 1.5: 1.0 and 3.0: 1.0: 0.5 (formaldehyde: urea: melamine), pressed together with a melamine barrier film and a known melamine decoration film.
