Description
Technical Field
The utility model relates to a self-adhesive enameled wire, in particular to an anti-offset self-adhesive enameled wire.
Background
The self-adhesive enameled wires can be subjected to secondary melting of the self-adhesive layer on the surface in a later heating or electrifying mode, so that paint films on the surfaces of the enameled wires are adhered to each other and gaps formed after the adjacent enameled wires are wound are filled; compared with the traditional enameled wire, the method can save a later paint dipping process, improves the environmental protection performance and the processing efficiency, and is more and more selected by factories. However, in the secondary bonding process of the self-adhesive paint layer on the surface of the enameled wire, the self-adhesive paint can move and fill towards the gap under a molten state, so that the self-adhesive paint is easy to cause displacement of the enameled wire core after flowing, namely the enameled wire core is not in an original position after secondary solidification, but can be mutually extruded to cause relative displacement and interval difference between adjacent enameled wires, and therefore winding stability and insulation effect of the enameled wire are affected.
Accordingly, there is a need for an enamel wire structure that can mitigate the flow-off of self-adhesive enamel from the surface.
Disclosure of Invention
The utility model aims to provide an anti-deviation self-adhesive enameled wire. The positioning function of the enameled wire can be realized, so that the offset of the enameled wire in secondary melting and the flow-off of self-adhesive paint are relieved.
The technical scheme of the utility model is as follows: the utility model provides an anti-deflection formula self-adhesion enameled wire, including the copper wire core, the surface of copper wire core is equipped with polyurethane priming paint layer, the outside of polyurethane priming paint layer is connected with the net layer through the enhancement layer, the enhancement layer is many annular distributions in the outside of net layer, the inboard of enhancement layer passes the net layer and connects polyurethane priming paint layer, the surface of enhancement layer extends to the net layer outside and forms the arch, the outside cladding of net layer and enhancement layer has the self-adhesive layer, the surface forms the burr portion of cooperation enhancement layer all around from the adhesive layer.
In the anti-offset self-adhesive enameled wire, the reinforcing layer is formed by coating polyester imide paint, and the reinforcing layer is of a strip shape and is formed by arranging a plurality of reinforcing layers side by side.
In the anti-offset self-adhesive enameled wire, the number of the reinforcing layers is 4-10.
In the anti-offset self-adhesive enameled wire, the thickness ratio of the reinforcing layer to the grid layer is 1.2-1.5:1.
In the anti-offset self-adhesive enameled wire, a concave part is formed between the adjacent reinforcing layers, the inner side of the self-adhesive layer positioned in the concave part penetrates through the grid layer and is attached with the polyurethane primer layer, and the grid layer is completely wrapped by the outer side of the self-adhesive layer.
In the anti-offset self-adhesive enameled wire, the thickness ratio of the self-adhesive layer to the mesh layer is 2-3:1.
Compared with the prior art, the self-adhesive layer can be adhered after being coated by the grid layer arranged outside the polyurethane primer layer, so that the flowing-away of the self-adhesive layer in secondary melting is reduced, the grid layer can be fixed through the reinforcing layer arranged on the grid layer, loose stripping of the grid layer is avoided, and the enameled wires can be limited after the self-adhesive layer is secondarily melted, so that the position stability of the adjacent enameled wires can be ensured under the separation of the polyurethane primer layer and the reinforcing layer, and the position deviation of the enameled wires is relieved; the relief portion formed after coating through the self-adhesive layer can be flattened under the extrusion effect when being melted for the second time, namely gaps between adjacent enamelled wires are filled by self-adhesive paint at the relief position, so that the flowing-away of self-adhesive paint on other positions is reduced, and the wrapping effect and insulativity of the self-adhesive paint on the enamelled wires are further improved. Therefore, the utility model can realize the positioning function of the enameled wire, thereby relieving the offset of the enameled wire in secondary melting and the flow-off of self-adhesive paint.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.
Examples. The anti-offset self-adhesive enameled wire is shown in fig. 1, and comprises a copper wire core 1, wherein a polyurethane primer layer 2 is arranged on the surface of the copper wire core 1, a grid layer 4 is connected to the outer part of the polyurethane primer layer 2 through a reinforcing layer 3, glass fiber grid cloth or plastic grid layers can be selected as the grid layer 4, the reinforcing layer 3 is distributed outside the grid layer 4 in a plurality of annular shapes, the inner side of the reinforcing layer 3 penetrates through the grid layer 4 and is connected with the polyurethane primer layer 2, the surface of the reinforcing layer 3 extends to the outer side of the grid layer 4 and forms a bulge, self-adhesive layers 5 are coated on the outer sides of the grid layer 4 and the reinforcing layer 3, a convex pattern part 6 matched with the reinforcing layer 3 is formed on the peripheral surface of the self-adhesive layers 5, and the thickness of the self-adhesive layers 5 at the convex pattern part 6 is basically consistent with the thickness of the non-convex pattern part 6.

The thickness ratio of the self-adhesive layer 5 to the grid layer 4 is 2-3:1.
The working principle of the utility model is as follows: when the enameled wires are subjected to secondary melting treatment after being wound, the self-adhesive layer 5 on the surface of the enameled wires is converted from a solid state into a molten state and flows to gaps between adjacent enameled wires; at this time, the self-adhesive layer 5 can be adhered by the grid layer 4 outside the polyurethane primer layer 2, so that part of self-adhesive paint cannot be completely separated from the grid layer 4 after being adhered, and the flow-off of the self-adhesive paint at the position of the concave part is reduced. Meanwhile, after the self-adhesive paint at the connecting positions of the adjacent enamelled wires flows away, the inner rings of the enamelled wires can be separated through the reinforcing layer 3, so that the mutual approaching of the adjacent enamelled wires after the self-adhesive paint flows away is relieved; the self-adhesive paint at the position can fill the gap after flowing away, so that the filling effect of the self-adhesive paint on the gap after secondary melting is ensured.
