Title:
HEAT-RESISTANT SELF-FUSING COATING AND HEAT-RESISTANT SELF-FUSING ENAMEL WIRE
Document Type and Number:
Japanese Patent JP2014167122
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat-resistant self-fusing enamel wire which exerts good thermal fusion force in a fusing step and shows thermal fusing force without practical problems even in a high-temperature atmosphere and a heat-resistant self-fusing coating used for the wire.SOLUTION: A heat-resistant self-fusing coating contains 10-100 pts.mass of a bismaleimide(s) to 100 pts.mass of a sulfone-containing polyhydroxypolyether resin of chemical formula (1) obtained by copolymerizing 50-70 mol% of a bisphenol A type epoxy units with 30-50 mol% of bisphenol S type epoxy units. A heat-resistant self-fusing enamel wire which has a fusion layer formed by applying the heat-resistant self-fusing coating, directly or through another insulator, onto a conductor and glazing is also provided.
