Abstract
The invention discloses a 108 degree special fine self-adhesion lacquered wire and a production method thereof. The 108 degree special fine self-adhesion lacquered wire is formed by baking a 0.03-0.200 mm copper conductor coated by an insulation layer, wherein the insulation layer is three layers of insulated coating, the insulated coating of the inner layer is 108 degree polyurethane coating, the insulated coating of the middle layer is 108 degree polyamide resin coating, and the insulating coating of outer layer is poly acetal resin coating. By adopting the equal speed and different temperature production technology used for a double-deck furnace enamelling machine, the invention solves the cross linking and solidification of three coating solutions with different characteristics, enables the three kinds of coating to be in the optimal solidification state, improves the lubricity and the wearing resistance of the lacquered wire, solves the problem of high-speed coiling of a coil, and can be fast molded by direct heat generation through friction.
Description
Technical field
The present invention relates to electric lead, relate in particular to enamelled wire.
Background technology
The develop rapidly of making rapid progress along with domestic electronics industry further enlarges as the demand of the enamelled wire of electronic product.Along with the continuous replacement upgrading of home products, the shared proportion of high-grade enamelled wire is increasing.Present high-grade enamelled wire mainly relies on import, especially the almost all imports of the high lubricated self-binding enamel wire of high heat-stage.It all is 130 grades or 155 grades of low-grade lines that China only produces the straight welding lacquered wire of self-adhesion, fire-retardant self-binding enamel wire, F level Self-binding cord and pure dissolubility Self-binding cord at present.In order to solve the dependence on import problem, must research and develop the expensive goods import substitutes.
Summary of the invention
The purpose of this invention is to provide a kind of 180 grades of special thin type self-adhesive enameled wires and production method thereof.
For achieving the above object, 180 grades of special thin type self-adhesive enameled wires of the present invention are to be coated with insulating barrier to cure and form on the 0.03-0.200mm copper conductor, it is characterized in that, described insulating barrier is three-layer insulated lacquer, wherein internal layer is 180 grades of polyurethane paints, the intermediate layer is 180 grades of polyamide insulating varnish, and is outer for gathering acetyl acetal insulation resin lacquer (claiming the self-adhesion lacquer usually).
Concrete processing method is:
1 selects the earlier annealed pipe annealing of copper conductor of diameter 0.03-0.200mm, annealing temperature 520-560 ℃ for use;
2, adopt felt japanning method, apply 180 grades of polyurethane paints 14-16 time earlier, the enamelling machine upper strata stove of double-deck furnace structure carries out baked and cured about being placed on then, and the baker curing temperature is 560-580 ℃;
3, adopt felt japanning method, apply 180 grades of polyamide insulating varnish again 6-8 time, be placed on above-mentioned enamelling machine upper strata stove then and carry out baked and cured, the baker curing temperature is 560-580 ℃;
4, adopt felt japanning method, apply poly-acetyl acetal insulation resin lacquer then 20-24 time, be placed on above-mentioned enamelling machine lower floor stove then and carry out baked and cured, the baker curing temperature is 530-550 ℃;
5, cool off the back at last around to bobbin, forming finished product.
Above-mentioned 180 grades of polyurethane paints, 180 grades of polyamide insulating varnish and poly-acetyl acetal insulation resin lacquer are the commercially available prod.Wherein:
180 grades of polyurethane paints: solids content 28 ± 1%, viscosity 25-35 second/20 ℃ are to be base with the polyurethane resin, form 180 grades of temperature index with cresols and dimethylbenzene modulation.
180 grades of polyamide insulating varnish: solids content 5 ± 1%, viscosity 40-50 second/20 ℃, 180 grades of temperature index.
Poly-acetyl acetal insulation resin lacquer (generally making self-adhesion coat with lacquer): solids content 10 ± 1%, viscosity 20-40 second/20 ℃.
Above-mentioned baker adopts the German MAG HS of company series double-deck furnace enamelling machine.
Advantage of the present invention is:
1, adopts the double-deck furnace enamelling machine with the speed production technology of equality of temperature not, solved the crosslinking curing between three kinds of different qualities lacquer liquid, make three kinds of lacquers can both reach best solid state.
2, this enamelled wire thermal level is up to 180 grades, and low temperature moulding is indeformable.
3, improve the lubrification and the resistance to wear of enamelled wire, solved the high speed winding difficult problem of coil, can direct friction give birth to hot rapid shaping.
4, guaranteed high strength bond, with the mass of coil height of its coiling.
Embodiment
Below in conjunction with concrete description of the process enforcement of the present invention.
At first select required specification lead for use, annealed pipe annealing under 520-560 ℃ of temperature, at first adopt felt japanning method to apply 180 grades of polyurethane paints 14-16 time at the lead internal layer, and carry out baked and cured on the enamelling machine upper strata of double-deck furnace structure, baker is cured as 560-580 ℃; Apply 180 grades of polyamide insulating varnish then 6-8 time, and carry out baked and cured on double-deck furnace enamelling machine upper strata, the baker curing temperature is 560-580 ℃; Apply poly-acetyl acetal insulation resin lacquer at last 20-24 time, and carry out baked and cured in double-deck furnace enamelling machine lower floor, the baker curing temperature is 530-550 ℃; The cooling back is around form finished product to bobbin.
