Abstract

Inventia se refera la un procedeu pentru obtinerea unor rasini epoxidofenolformaldehidice, utilizabile în electrotehnica, la fabricarea de mase de presare si materiale stratificate electroizolante. Rasinile sînt obtinute prin copoliaditia unei rasini epoxidice la rasini fenolformaldehidice sau alchilfenolformaldehidice.The invention relates to a process for obtaining epoxy-phenol-formaldehyde resins, usable in electrical engineering, for the manufacture of pressed masses and electro-insulating layered materials. The resins are obtained by the co-ordination of an epoxy resin with phenol-formaldehyde resins or alkylphenol-formaldehyde resins.
