SELF-LUBRICATION INSULATED ELECTRIC WIRE

摘要

PROBLEM TO BE SOLVED: To enable an insulated electric wire to be effectively manufactured without using ammonia water for dispersion by providing an insulation film containing a fluoro compound having a polymer contain its circular structure expressed by a specific chemical formula directly on a lead wire or via an insulation layer. ;SOLUTION: An insulation film containing a fluoro compound having a polymer including its circular structure expressed by a formula I (where l, m, n are 0 or positive integers) or formula II (where R₁ to R₄ are fluorine atoms or fluoro-alkyl groups) is provided directly on a lead wire or via an insulation layer. That is, an insulation coat composed of a polymer containing its circular structure expressed in formula I or formula II being dissolved in an organic solvent is coated, and the insulation film in which the solvent in the solution is made volatile is provided and manufactured. Therefore, this insulation film is even and is superior in stability, is a superior lubricant layer, is never produced when an ammonia is applied, and adversely affect a sintering machine such as corrosion.;COPYRIGHT: (C)1998,JPO
