Abstract
The utility model relates to a 130-grade enameled wire, which comprises a copper core. The 130-grade enameled wire is characterized in that a tin coating layer is arranged on the surface of the copper core; a polyurethane insulating coating layer is further arranged on the surface of the tin coating layer; and the temperature of the polyurethane insulating coating layer is ranked 130th. The 130-grade enameled wire provided in the utility model has the advantages of excellent auto adhesion, good chemical resistance, and great working performances. The enameled wire is especially suitable for welding.
Description
Technical field
The utility model relates to a kind of enamelled wire, is specifically related to a kind of 130 grades of enamelled wires.
Background technology
Along with domestic electronics industry high speed development with rapid changepl. never-ending changes and improvements, enamelled wire has been widely used in every field, continuous replacement upgrading along with home products, people are increasing to the demand of high-quality enamelled wire, the electromagnetic wire product of taking as the leading factor with enamelled wire is from developing the higher new varieties of thermal endurance, turn to the innovation of product structure and coating, to reach the performance level that improves enamelled wire and the purpose of improving processing characteristics.Copper-in-aluminum enameled wire in the past is when producing and make electronic component, because copper has catalytic action to the aging of coat of paint, so the copper surface very easily forms oxidation spots, when it carries out the finished product welding, rosin joint, dry joint phenomenon often can occur, affects product quality.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of conductivity is good, 130 grades of enamelled wires of stable chemical performance, suitable especially welding.
For achieving the above object, the utility model provides following technical scheme: a kind of 130 grades of enamelled wires, comprise copper core, it is characterized in that: described copper core surface is provided with tin coating, described tin coating surface also is provided with the polyurethane insulating coating, and the temperature rank of described polyurethane insulating coating is 130 grades.
By adopting technique scheme, tin coating has been isolated copper core and insulating coating, thereby it is aging to delay insulating coating, also can prevent the copper core oxidation simultaneously, and then prevent from occurring in the welding process rosin joint and dry joint phenomenon.
The utility model further is set to: described polyurethane insulating coating surface also is covered with the self-adhesion enamelled coating.
The utility model further is set to: described self-adhesion enamelled coating is poly-acetyl acetal insulation resin paint film.
The beneficial effects of the utility model are: have good tack, and chemical resistance, transaction capabilities is good, suitable especially welding.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the utility model embodiment cross-sectional structure schematic diagram.
Embodiment
Referring to accompanying drawing 1, the disclosed 130 grades of enamelled wires of the utility model comprise copper core 4, and copper core 4 surfaces are provided with tin coating 3, and tin coating 3 surfaces also are provided with polyurethane insulating coating 2, and the temperature rank of polyurethane insulating coating 2 is 130 grades.
By adopting technique scheme, tin coating 3 has been isolated copper core 4 and polyurethane insulating coating 2, thereby it is aging to delay polyurethane insulating coating 2, also can prevent copper core 4 oxidations simultaneously, and then prevent from occurring in the welding process rosin joint and dry joint phenomenon.
In the present embodiment, polyurethane insulating coating 2 surfaces also are covered with self-adhesion enamelled coating 1.
In the present embodiment, self-adhesion enamelled coating 1 is poly-acetyl acetal insulation resin paint film.
Present embodiment has good tack, chemical resistance, and transaction capabilities is good, suitable especially welding.
