Abstract
Inventia se refera la o compozitie de lac electroizolant pentru conductorii de cupru pe baza de polivinilformal, rasini fenolice, epoxidice, poliuretanice, dizolvate în tricrezol si solventi aromatici, ce conduce la un email cu proprietati mecanice superioare si chimice superioare. Lacul conform inventiei este constituit din 10...80 parti polivinilformal, 10...30 parti rasina fenol-formaldehidica, 1...30 parti rasina epoxidica, 1...80 parti rasina poliuretanica si în calitate de solvent un amestec în parti egale de tricrezol si solventi aromatici, având un continut în solide de 16....22%.The invention relates to a composition of insulating varnish for copper conductors based on polyvinylformal, phenolic, epoxy, polyurethane resins, dissolved in tricrezol and aromatic solvents, leading to an email with higher mechanical and superior mechanical properties. The lake according to the invention consists of 10 ... 80 parts of polyvinyl formal, 10 ... 30 parts of phenol-formaldehyde resin, 1 ... 30 parts of epoxy resin, 1 ... 80 parts of polyurethane resin and as a solvent mixture in equal parts of tricrezol and aromatic solvents, having a solids content of 16 ... 22%.
