NANOMODIFIED WIRE ENAMELS AND ENAMELLED WIRE Russian patent published in 2013 - IPC C09D7/12 C09D5/25 C09D175/04 C09D167/00 C09D179/08 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to use of nanomaterials in wire enamel for improving thermal properties of enamel. The nanomodified wire enamels are usually used in making insulated winding wire. The polymer base of wire enamel is selected from a group comprising polyamideimide, polyester, polyesterimide, polyurethane and mixtures thereof. The nanomaterial is selected from a group comprising nano-oxides, metal nano-oxides, metal oxides or hydroxides of aluminium, tin, born, germanium, gallium, lead, transition metals, lanthanides, actinides and mixtures thereof. The nanomaterial is also selected from a group comprising nano-oxides, metal nano-oxides, metal oxides and hydroxides of aluminium, silicon, titanium, zinc, yttrium, vanadium, zirconium, nickel and mixtures thereof. After applying enamel on the wire and curing thereof, the wire exhibits improved thermal and mechanical properties.

EFFECT: improved thermal properties of enamel.
