Abstract
The invention relates to a method for manufacturing a 240-level special fine enameled wire, which comprises the following steps of: after annealing a special fine copper wire, painting the annealed special fine copper wire; then, baking the painted special fine copper wire, and then cooling. The invention is characterized in that an ambient temperature for painting the special fine copper wire is not more than 19 DEG C and is not less than -5 DEG C. The enameled wire manufactured by utilizing the method has the advantages of normal felt softness and smooth wire coated surfaces; furthermore, the invention prevents interference brought by change of climates and seasons, and greatly increases availability and productivity in unit time.
Description
Technical field
What the present invention relates to is a kind of manufacture method of 240 level special fine copper enamelled wires.
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.And upgrade along with the continuous replacement of product, high-grade enamelled wire proportion is increasing.At present, high-grade enamelled wire mainly relies on import, especially 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, for this reason, just the someone has researched and developed 180 grades of more high-grade special thin type enamelled wires.Look into Chinese patent database, wherein a number of patent application is 200910014864.8, denomination of invention discloses following content for " 180 grades special thin type self-adhesive enameled wire and production method " thereof: these 180 grades of special thin type self-adhesive enameled wires are to be coated with insulating barrier to cure and form on 0.03-0.200 millimeter 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, outer for gathering acetyl acetal insulation resin lacquer, its concrete processing method is: adopt the earlier annealed pipe annealing of copper conductor of diameter 0.03-0.200 millimeter, annealing temperature 520-560 degree centigrade 1.; 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 degree centigrade; 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 degree centigrade; 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 degree centigrade; The cooling back is around form finished product to bobbin at last.And this production method when applying each layer insulating varnish, is all carried out at normal temperatures.Want to produce more high-grade enamelled wire, ultrafine enameled wire as 240 grades, because the insulating varnish of 240 grades of ultrafine enameled wire employings is aromatic polyimide lacquers, when if this insulating varnish also applies at normal temperatures, just find felt sclerosis, felt crack have beans big solidify lacquer, be coated with the scared phenomenon in line surface, so, can not be suitable for 240 grades of ultrafine enameled wires with existent method.
Summary of the invention
In view of the deficiency that background technology exists, it is soft normal that the technical problem to be solved in the present invention provides a kind of its felt of 240 level special fine enameled wires that can make, and is coated with the normal manufacture method of line smooth surface.
For this reason, the present invention adopts following technical scheme to realize: a kind of manufacture method of 240 level special fine enameled wires has following steps:
A), with the annealed processing of the fine copper cash of spy;
B), the special fine copper cash of annealing in process is painted;
C), cure, and then cool off through the special fine copper cash of japanning;
It is characterized in that the described ambient temperature that the fine copper cash of spy is painted is not more than 19 degrees centigrade, is not less than subzero 5 degrees centigrade.
Felt method or die methods are adopted in described japanning.
The method applied in the present invention, when producing 240 level special fine enameled wires, the interference of having avoided weather, seasonal variations to bring can be guaranteed low temperature, constant temperature production, has improved utilance and the productivity ratio of unit interval greatly.
Embodiment
Specifically describe embodiments of the present invention below again.
The manufacture method of this 240 level special fine enameled wires is earlier the fine copper cash of spy annealed pipe under 500-600 degree centigrade temperature to be carried out annealing in process; Then the fine copper cash of spy being placed on an ambient temperature is controlled in-5 ~ 19 degrees centigrade the space of relative closure, adopt felt method or die methods that the special fine copper cash of annealing in process is applied the aromatic polyimide lacquer, to cure through the special fine copper cash of japanning again, and then cool off; Just become 240 level special fine enameled wires.The space temperature of above-mentioned relative closure more than 10 degrees centigrade the time, can adopt common air-conditioning to regulate control, when being lower than 10 degrees centigrade, can adopt refrigeration that temperature is regulated and controlled.In fact Celsius, its process of annealing, curing, cool off is same as the prior art, therefore also just repeats no more.
Claims (2)
1. the manufacture method of a level special fine enameled wire has following steps:
A), with the annealed processing of the fine copper cash of spy;
B), the special fine copper cash of annealing in process is painted;
C), cure, and then cool off through the special fine copper cash of japanning;
It is characterized in that the described ambient temperature that the fine copper cash of spy is painted is not more than 19 degrees centigrade, and be not less than subzero 5 degrees centigrade.
2. the manufacture method of 240 level special fine enameled wires according to claim 1 is characterized in that described japanning employing felt method or die methods.
