Patent ID: 7851705

Claim:
An insulated wire, comprising a metallic conductor, an insulating coating layer formed thereon, and a self-lubricating layer formed as an outermost layer on the insulating coating layer; wherein the self-lubricating layer is made by mixing a polyamideimide resin coating with a stabilized isocyanate compound, a wax and an antioxidant; and wherein a resin coating layer composed of the insulating coating layer and the self-lubricating layer has a dynamic hardness DH represented by formula (1) of 0.6 or more: DH= 3.8584 ×P /( D×D ) Formula (1) wherein P (mN) represents a load when a triangular pyramid indenter with tip angle of 115° is pressed against the surface of the resin coating layer, and D (μm) represents the indentation depth by the triangular pyramid indenter to the surface of the resin coating layer; and wherein a tin catalyst is further mixed with the polyamideimide resin coating in an amount of 0.05 to 5.0 mass parts based on 100 mass parts of the polyamideimide resin.
