ELECTRICAL WIRE WITH MINERAL LAYER

摘要

An electrical wire comprises a metallic electrically conductor and an insulating mineral layer which is electrolytically formed on the conductor from a micaceous mineral and which includes a polymeric binder that has been co-deposited on the conductor from a polymer latex. Preferred latex binders include styrene/butadiene/styrene rubbers, polyvinyl acetate, acrylyic copolymers and polyvinylidine chloride. The use of a latex binder enables the micaceous mineral coating to be dried quickly during manufacture of the wire and enables hydrophobic binders to be employed.
