Abstract
Compozitie de lac electroizolant solubil în apa pentru table electrotehnice, pe baza de rasini, caracterizata prin aceea ca, în scopul reducerii temperaturii de aplicare a lacului pe tabla si respectiv diminuarii consumului de energie, a realizarii unei pelicule uniforme si fara striatii longitudinale pe suprafata, si a asigurarii unei rezistivitati dielectrice superioare prin eliminarea riscului de crapare si exfoliere a peliculei de lac de pe tabla la îndoiri repetate, este formata din 40...75 parti dintr-un amestec de rasini sintetice solubile în apa, constituit din rasini alchidice solubile în apa si rasini alchil sau arilfenolformaldehidice neeterificate....The invention relates to a water-soluble electro-insulating lacquer for resin-based electrotechnical sheets, characterized in that in order to reduce the application temperature of the lacquer on the sheet and to reduce the energy consumption, to achieve a uniform film without longitudinal striations on the surface, and providing superior dielectric resistivity by eliminating the risk of cracking and peeling of the lacquer film on the sheet at repeated bends is comprised of 40 ... 75 parts of a water-soluble synthetic resins mixture consisting of soluble alkyd resins in water and non-esterified alkyl or aryl-phenolformaldehyde resins ....
