Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, a flat enameled wire structure includes a wire 1 having a rectangular cross-section and an insulating layer 2 coated outside thereof.
The insulating layer 2 is used for preventing the wire from contacting with the outside to cause electric leakage, short circuit, electric shock and the like, and simultaneously protecting the wire and preventing the wire from being broken and the like, in order to realize the tight contact between the insulating layer 2 and the wire 1, the insulating layer 2 is formed by spraying insulating paint on the outside of the wire 1 in a coating mode and then curing the insulating paint in a baking mode, and researches show that compared with a single material, the heat resistance, the pressure resistance, the tensile resistance, the service life and other properties of the composite insulating layer made of multiple materials are remarkably improved, so that the insulating layer 2 adopts the composite insulating layer and comprises a primer layer 201, a finish layer 202 and a protective coating 204 from inside to outside, wherein the primer layer 201 and the finish layer 202 are made of different materials through spraying and are all made of insulating paint allowed to be used in the field and comprise but not limited to epoxy resin paint, straight-welding polyester, Modified polyester paint, polyester paint and the like, and the protective coating 204 is formed by spraying water-based high-temperature-resistant paint. Priming paint layer 201 and finish paint layer 202 form compound insulating paint layer, utilize two kinds of different insulating paint to play dual even multiple effect, outer finish paint has played the guard action and has strengthened insulating comprehensive properties simultaneously and in addition single insulating paint cost consumption reduces, outermost waterborne high temperature resistant paint simultaneously utilizes its wider temperature resistant range and lower coefficient of heat conductivity, improves its heat resistance, resistant freezing nature, simultaneously waterproof, corrosion-resistant, play the guard action to inside compound insulating layer, and then avoid its thermal ageing and electrical ageing.
Because the priming paint layer 201 and the finishing paint layer 202 are formed by spraying two insulating paints made of different materials, in order to improve the combination performance of the priming paint layer 201 and the finishing paint layer 202, a plurality of groups of inwards concave embedded parts 203 are uniformly distributed on the outer surface of the priming paint layer 201, and protruding parts matched with the embedded parts 203 are arranged on the finishing paint layer 202. So that the contact area of the primer layer 201 and the finishing paint layer 202 is larger and the combination is more stable.
In specific implementation, after the primer layer 201 is coated and baked, the surface of the primer layer 201 is partially recessed by a mold before being completely cured, and then the embedded portion 203 is formed and then cured at high temperature, so that after the primer layer 201 is formed, the insulating paint of the finish paint layer 202 is sprayed on the surface of the primer layer, the finish paint layer 202 is formed after baking and curing, and then the water-based high-temperature resistant paint is sprayed on the finish paint layer 202, and the protective coating 204 is formed after high-temperature curing.
The thickness of the primer layer 201 is greater than that of the finish layer 202, the thickness of the finish layer 202 is greater than that of the protective coating 204, and the thickness of the primer layer 201 and the thickness of the finish layer 202 do not include the embedded portion 203 and the protruding portion, which means the thickness of the straight region. The thickness ratio of the protective coating 204 to the finish paint layer 202 to the primer layer 201 is 1: 2-4: 6-9.
In order to enable the insulating layer 2 not to be prone to physical damage caused by collision and other reasons in the use process, four corners of the insulating layer 2 are round chamfers, and four corners of the protective coating 204, the finish paint layer 202 and the primer paint layer 201 are round chamfers. The ridge line is changed into a smooth cambered surface, so that the practicability is better.
The wire 1 is a composite bimetallic wire, including the interior aluminium core 101 of rectangle and the outer copper layer 102 of wrapping up interior aluminium core 1, the wire that market commonly used is pure aluminium core or copper core, wherein use the copper core as the main, it is extensive with wide application in power cable and signal cable, and the electric conductivity is mainly influenced by the material and the surface area of surface material with signal transmission's performance, and the copper use amount can be greatly reduced by the composite bimetallic wire of copper skin parcel aluminium core, reduce cost. In order to ensure the performance of the conducting wire or signal transmission, the thickness of the outer copper layer 102 is 10% -25% of the total thickness of the conducting wire 1, and the total thickness of the conducting wire 1 refers to the narrow margin value of the flat conducting wire.
The foregoing merely illustrates preferred embodiments of the present invention, which are described in considerable detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes, modifications and substitutions can be made, which are all within the scope of the present invention.
