Abstract

The utility model discloses a high heat-resistant enameled round aluminum wire with three coatings. The high heat-resistant enameled round aluminum wire with the three coatings comprises an aluminum conductor, an inner layer, a middle layer and an outer layer, wherein the aluminum conductor is coated by three coating layers, the inner layer is a modified polyester paint coating layer, the middle layer is a polyester imide paint coating layer, and the outer layer is a polyester amine ester imide paint coating layer. The high heat-resistant enameled round aluminum wire with three coatings is reasonably structured and is difficulty in film rupture, and can prevent electricity leakage.

Description

A kind of three are coated with floor height Berlin black bag aluminium round wire

Technical field

The utility model belongs to the enamelled wire field, and what relate generally to is a kind of three to be coated with floor height Berlin black bag aluminium round wire.

Background technology

Lasting high along with copper valency in recent years, the aluminium of enamelled wire conductor occurs for copper products in succession, and its production technology is on the whole identical with the copper conductor enamelled wire; Earlier the aluminium bar is drawn into the aluminum steel of corresponding specification; At its surface-coated corresponding insulation paint, this product is applied on the products such as microwave oven, transformer, refrigerant compressor again, because the characteristics of aluminium conductor itself; Make that the temperature rise of aluminium enamel-covered wire is big than copper cash, this requires by force with regard to the temperature capacity that requires aluminium enamel-covered wire.According to present enamel insulated aluminium wire manufacturing technology and technology; And corresponding national, international standard requirement; The practicality that the product of producing often can't reach the user requires: after coil winding machine high speed, hightension coiling, aluminium enamel-covered wire can't bear, thereby the problem that paint film breaks, leaks electricity takes place; Perhaps use back turn-to-turn electric current excessive, perhaps can't stand long high temperature environment for use and burn through energising.There is safety problem in therefore existing enamelled wire aluminium round wire.

The utility model content

The technical problem that the utility model will solve is: overcome the deficiency that prior art exists, provide a kind of three to be coated with floor height Berlin black bag aluminium round wire, be mainly used in and solve the safety problem that the easy generation of enamelled round aluminium wire with paint film breaks, leaks electricity.

The technical scheme that its technical problem of the utility model solution is taked is: a kind of three are coated with floor height Berlin black bag aluminium round wire; It comprises the coat of paint of aluminum conductor and parcel aluminum conductor; The described coat of paint is three layers; Internal layer is a modified polyester paint application layer, and the middle level is a polyester-imide paint application layer, and skin is a polyesteramine ester imines paint application layer.Owing to adopt modified poly ester imines paint application layer as basic unit; Overcome polyester-imide paint effectively as basic unit and the not enough problem of aluminium conductor surface combination power; Avoided aluminium enamel-covered wire to lose the problem of tack; Again because inter coat uses polyester-imide paint application layer, so its heat-resisting and anti-solvent, particularly cold-resistant matchmaker's problem are resolved.Skin is coated polyester amine ester imines paint application layer again, make aluminium enamel-covered wire especially thermal level brought up to 200 degree, simultaneously skin-friction coefficient greatly reduces, what be stretched in the use is much smaller.

The beneficial effect that the utility model is obtained is: owing to adopt three layers of different paint application layer; Make the utility model avoid aluminium enamel-covered wire to lose the problem of tack; Its heat-resisting and anti-solvent, particularly cold-resistant matchmaker are effective; Skin makes thermal level bring up to 200 degree, and skin-friction coefficient greatly reduces simultaneously, and what be stretched in the use is much smaller.

Embodiment

As shown in Figure 1: a kind of three are coated with floor height Berlin black bag aluminium round wire; Form by aluminum conductor 1, internal layer 2, middle level 3 and outer 4; Said aluminum conductor 1 is by coat of paint parcel, and the coat of paint is three layers, and internal layer 2 is a modified polyester paint application layer; Middle level 3 is a polyester-imide paint application layer, and outer 4 is polyesteramine ester imines paint application layer.

What should explain at last is: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has carried out detailed explanation to the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and the scope of the utility model, and it all should be encompassed in the claim scope of the utility model.

Claims

1. one kind three is coated with floor height Berlin black bag aluminium round wire, and by aluminum conductor, internal layer, middle level and outer the composition, said aluminum conductor is wrapped up by the coat of paint; The coat of paint is three layers; Internal layer is a modified polyester paint application layer, and the middle level is a polyester-imide paint application layer, and skin is a polyesteramine ester imines paint application layer.
