Abstract
An enamel insulated round aluminium wire and a production method thereof relate to the technical field of the production of the enamel insulated wire. The production method comprises the following steps: stretching an aluminium rod to form an aluminium wire, and then performing annealing, cooling, drying, painting and taking-up steps to the aluminium wire in turn. The method is characterized in that in the painting step, self-adhering paint is painted on the surface of the aluminium wire which is preheated to 50+/-10 DEG C at least once, the aluminium wire is dried and cooled to 50+/-10 DEG C, then polyesterimide paint is painted on the aluminium wire 5-7 times, the aluminium wire is dried and cooled to 50+/-10 DEG C, and polyesterimide paint is painted 3-6 times. By adopting the enamel insulated round aluminium wire, the cost can be greatly reduced and the adhesive force of the paint film can be increased; and the round aluminium wire is characterized by low cost and high durability.
Description
Technical field
The present invention relates to the Production of Enamel Wires technical field.
Background technology
Owing to the easy oxidation of aluminium bar with than low melting point, cause the control of more harsh cleaning requirement of aluminum steel and temperature, and the aluminum steel degree of drawing is big, easier stretching so aluminum steel adhesive force is difficult to control, causes the obstacle of aluminum steel promotion and application.In addition, be conductor because existing enamelled wire adopts copper mostly, cause the Production of Enamel Wires cost high.
Summary of the invention
The objective of the invention is: a kind of enamelled round aluminium wire with good adhesion is provided.
The object of the present invention is achieved like this: comprise the aluminium core, the aluminium core sets gradually polyester-imide enamelled coating and polyamidoimide enamelled coating outward, is characterized in: be coated with the self-adhesion enamelled coating between described aluminium core and described polyester-imide enamelled coating.
The present invention is conductor material with aluminium, and the instead of copper conductor can make cost reduce greatly.Adopt the self-adhesion lacquer to carry out the primary coat construction on the aluminum steel surface, and then be coated with polyester-imide lacquer and polyamidoimide lacquer, because the adhesive effect of self-adhesion lacquer has greatly improved paint film adhesion; The enamelled round aluminium wire with employing test method identical with copper cash more than 2.00mm done adhesion test and all passed through smoothly.Especially to major diameter, particularly the above aluminium round wire of 4.00mm adopts and more adds tight 1D method for winding than copper cash and do adhesion test, can both pass through smoothly.Therefore, the present invention has the characteristics of low-cost and high durability.
Another purpose of the present invention is to provide a kind of production method to above invention product:
Earlier to the aluminium bar formation aluminum steel that stretches, then successively to aluminum steel anneal, cool off, dry, japanning and take-up step, its point is: when japanning, be coated with the self-adhesion lacquer on the aluminum steel surface that is preheated to 50 ± 10 ℃ earlier and carry out at least one time, the oven dry and be cooled to 50 ± 10 ℃ after, be coated with polyester-imide lacquer again and carry out 5 to 7 roads, dry and be cooled to 50 ± 10 ℃ after, be coated with the polyamidoimide lacquer and carry out 3 to 6 roads.
Be coated with the inlet temperature of carrying out the drying plant behind the corresponding paint vehicle is 300 ± 20 ℃ at every turn, and curing temperature is 500 ± 20 ℃, and the circulating fan rotating speed is 1800～2200 rev/mins, and the waste discharge rotation speed of fan is 1200～1800 rev/mins.
Technology of the present invention is simple, reasonable, is beneficial to production control, and product stability is good.
For convenience of unwrapping wire, the present invention also can carry out the surface before take-up oily.

5,50 ± 10 ℃ semi-finished product that scribble polyester-imide lacquer are soaked from the polyamidoimide lacquer dragged, entering drying plant then dries, the inlet temperature of drying plant is 300 ± 20 ℃, curing temperature is 500 ± 20 ℃, the circulating fan rotating speed is 1800～2200 rev/mins, and the waste discharge rotation speed of fan is 1200～1800 rev/mins.To be cooled after 50 ± 10 ℃, from the polyamidoimide lacquer, soak for the second time again and dragged, enter identical drying plant then and carry out the oven dry second time.Circulation is successively carried out the polyamidoimide lacquer in 3 to 6 roads altogether and is handled, and last standard forms aluminium enamel-covered wire but to normal temperature.
6, it is oily to enter the surface as requested at aluminium enamel-covered wire.
7, take-up.
The product that forms as shown in Figure 1, enamelled round aluminium wire with comprises aluminium core 1, scribbles self-adhesion enamelled coating 2 aluminium core 1 outside, self-adhesion lacquer 2 scribbles polyester-imide enamelled coating 3 and polyamidoimide enamelled coatings 4 outward successively.
