Abstract
The utility model discloses a copper-clad copper composite self lubricating varnished wire. The copper-clad copper composite self lubricating varnished wire comprises a brass core wire, a uniformly distributed red copper layer is coated on the outer wall of the brass core wire, and an insulating base coat layer is coated on the outer wall of the red copper layer; at least one self lubricating surface layer containing a lubricating agent and an organosilicon active agent is coated on the outer wall of the base coat layer, the thickness of the red copper layer is between 1 mm and 3mm, and the thickness of each self lubricating surface layer is between 2mm and 3mm. On the condition of not reducing technical indexes, the copper-clad copper composite self lubricating varnished wire enables the cost to be reduced greatly and the service life of wire rod to be improved effectively, and is also suitable for the manufacture and use of a high speed automation winding electric appliance.
Description
Technical field:
The utility model relates to transfer wire, particularly a kind of copper-clad copper composite self-lubricating enamelled wire that is applicable to the electrical equipment manufacturing use of high-speed automated coiling.
Background technology:
Present copper paint envelope curve is the external diameter coating one deck polyester-imide prime coat at a heart yearn, applies one deck polyamidoimide top coat layer at the prime coat external diameter again.The enamelled wire of this structure, though can satisfy International Power IEC to the requirement of every performance index, in the electrical equipment manufacturing of high-speed automated coiling was used, because adopt the line fine copper as core, cost was higher; In addition because surface layer because there is not the lubricant composition in the surface layer, so wearing coefficient and self-lubricating effect are poor, easily with the lead wearing and tearing, reduce useful life, even causes short trouble in drawing process.
Summary of the invention:
The purpose of this utility model provides a kind of low cost of manufacture, and self-lubricating effect is good, is suitable for the copper-clad copper composite self-lubricating enamelled wire of the electrical equipment manufacturing use of high-speed automated coiling.
The technical solution of the utility model is finished as follows, a kind of copper-clad copper composite self-lubricating enamelled wire, it includes a brass heart yearn, it is characterized in that: be coated with the uniform red copper layer of one deck at brass heart yearn outer wall, outer wall at the red copper layer is coated with the insulation prime coat, is coated with the self-lubricating surface layer that one deck at least contains lubricant and organosilicon activating agent at the prime coat outer wall.The thickness of red copper layer is between the 1-3 millimeter.The thickness of each self-lubricating surface layer is respectively between the 2-3 millimeter
The utility model not only makes cost greatly reduce under the situation that does not reduce every technical indicator, can be applicable to that also the useful life of having improved wire rod is effectively used in the electrical equipment manufacturing of high-speed automated coiling.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe embodiment by reference to the accompanying drawings in detail, the utility model is improvements over the prior art, it includes a brass heart yearn 1, be coated with the uniform red copper layer 2 of one deck at brass heart yearn outer wall, the thickness of red copper layer is between the 1-3 millimeter, and coating method is that the brass heart yearn is repeatedly applied the composite conductor wire rod that forms with drawing at cathode copper fusing fluid back warp.On the outer wall of red copper layer, apply one deck insulation prime coat 3 then earlier, the self-lubricating surface layer 4 and 5 that contains lubricant and organosilicon activating agent after the prime coat oven dry again in prime coat outside applied in two coats successively, between the 2-3 millimeter, the lubricating fluid baking is compounded to form product of the present utility model to the thickness of each self-lubricating surface layer in the box through lubricating again at last respectively.The utility model is through evidence, and every performance index meet national standard fully, can effectively reduce enamelled wire and stretch to the destruction of epithelium, and the fault that coil of wire turn-to-turn is short-circuited significantly reduces, and has vast market prospect.
