Self-adhesive Enameled Wire
Introduction
A self-adhesive enameled wire comprises a metal wire core, and an insulation varnish layer arranged outside the metal wire core, and a self-adhesive paint layer is coated outside the insulation varnish layer. As the self-adhesive paint layer is arranged outside the insulation varnish layer, the enameled wire is good in bonding performance and can be bonded without dipping paint, the technology can be simplified, and costs can be reduced.
Background Technology
At present, in the production field of enamelled wire,, apply one deck paint film as insulating barrier in the outside of conductor cores then by the conductor cores of pure copper material as enamelled wire.This enamelled wire does not have adhesive layer, thereby does not have the self-adhesion performance, and coil molding is bad, and easy loose, overall mechanical strength is low.Therefore, this enamelled wire also need pass through operations such as dipping lacquer is bonding, barbecue after being made into winding or coil molding, the manufacture craft more complicated, and cost is high.
Summary of the Invention
The technical scheme that the utility model solves its technical problem is: a kind of self-adhesive enameled wire comprises the metal core and is positioned at the outer insulation enamelled coating of this metal core that said insulation enamelled coating is coated with the self-adhesion enamelled coating outward.
Further, the self-adhesion enamelled coating that said self-adhesion enamelled coating is a heat molten type through the energising heating, can make the enamelled wire moulding; Perhaps, the self-adhesion enamelled coating that said self-adhesion enamelled coating is the alcohol type through the immersion of solvent solution, can make the enamelled wire moulding.
Further, said insulation enamelled coating is the polyurethane enamelled coating, and the polyurethane enamelled coating makes and the utlity model has straight weldering property, when needs weld, need not to scrape off the polyurethane enamelled coating, can directly the utility model be placed in the welding position of wanting and weld.The polyurethane enamelled coating also has the characteristic of anti-high frequency, and under high frequency environment, the dielectric loss of polyurethane enamelled coating is very low.In addition, can also sneak into various dyestuffs in the polyurethane coating, can make the utility model when work, be convenient to distinguish not collinear function and purposes so that enamelled wire presents various colors.
Further, said polyurethane enamelled coating has eight layers, makes that the thickness of polyurethane enamelled coating is moderate, can be anticreep, and insulation effect is better.
The beneficial effect of the utility model is: owing to be outside equipped with the self-adhesion enamelled coating at the insulation enamelled coating, thereby make and the utlity model has good adhesive property that it is bonding to need not dipping lacquer, simplifies technology, reduces cost.
