While, electrical insulating property is excellent.By anti-oxidation tin layers and the respective excellent properties of two layers of insulating lacquer layer, this paint is effectively improved
The performances such as the attachment stability of envelope curve entirety paint film and wear-resisting, cracking resistance, thus can be more stable when enameled wire is flattened
Progress.
Be further arranged to: the outer surface of the blocked polyurethane insulated paint is attached with metal oxide particles.
By using above-mentioned technical proposal, further promoted enameled wire outermost layer blocked polyurethane insulated paint it is wear-resisting,
Anti-cracking performance.
Be further arranged to: surface lubricant, the table is also coated in the outer surface of the blocked polyurethane insulated paint
Face lubricant is the alkyl lubricating oil of the C25 containing 0.05%-0.1%.
By using above-mentioned technical proposal, can guarantee product in use using surface lubricant has lower rub
Coefficient is wiped, convenient for automation all kinds of coils of coiling, improves the performance of product.
Be further arranged to: the blocked polyurethane insulated paint with a thickness of 0.05mm ~ 0.08mm.
Be further arranged to: the anti-oxidation tin layers with a thickness of 0.01mm ~ 0.02mm.
Be further arranged to: the polyamide-imide insulating varnish with a thickness of 0.03mm ~ 0.05mm.
It is further arranged to: the thickness of the organosilicon modified polyester insulated paint or organosilicon modified polyester imines insulated paint
For 0.02mm ~ 0.4mm.
By using above-mentioned technical proposal, outermost blocked polyurethane insulated paint thickness accounting is larger to make enameled wire
Have in use more stable, while more metal oxide particles can also be adhered to, enhance the wear-resisting property of enameled wire；
Anti-oxidation tin layers its thickness accounting when guaranteeing effectively to carry out protection against oxidation to copper inner core is smaller as far as possible to be can avoid to enamel-cover
Line mechanical performance produces bigger effect.
Be further arranged to: the temperature grade of the polyamide-imide insulating varnish is 220 grades.
By using above-mentioned technical proposal, since polyamide-imide insulating varnish is in more outer layer, to select temperature etc.
High 220 grades of grade are more advantageous to this enameled wire and work under high temperature environment, and then improve the stability in use of enameled wire.
In conclusion the advantageous effects of the utility model are as follows:
(1) by between anti-oxidation tin layers and organosilicon modified polyester insulated paint or organosilicon modified polyester imines insulated paint
Stable adhewsive action improves the adhesive force of enameled wire entirety paint film, to improve the stability of enameled wire；
(2) enameled wire outermost layer paint layer selects blocked polyurethane paint layer and addition metal oxide particles make to paint on it
The wear-resisting of envelope curve, anti-cracking ability are higher, extend the service life of enameled wire.
