Description

Technical Field

[0001] The invention belongs to the field of electricity, and relates to the field of electric wires, in particular to a Teflon electric wire and a manufacturing process thereof. Background Art

[0002] Due to its excellent non-stickiness and corrosion resistance, Teflon material is widely used in the field of wires. However, during long-term use, due to the thermal effect of electric current, the metal conductor will generate heat, and the Teflon material in direct contact with the metal conductor will gradually melt and bond to the conductor, causing the conductor resistance to increase and affecting the normal use of electrical appliances in the circuit. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a Teflon wire and a manufacturing process thereof, and the specific technical solution is as follows:

[0004] A Teflon electric wire comprises a metal conductor and a Teflon layer. The metal conductor is provided with a metal-plated layer, the metal-plated layer is coated with a glue layer on the outside, and the glue layer is connected to the Teflon layer on the outside.

[0005] In the Teflon wire, a protective metal layer is coated on the outside of the metal conductor, which does not affect its conductive performance and can prevent the metal from directly contacting the Teflon. A glue layer is provided between the metal and the Teflon to prevent the Teflon from expanding and contracting due to heat and causing the wire itself to feel patchy. With the glue layer, after the glue layer dries up, the space between the Teflon and the metal protective layer can feel full, making the appearance more beautiful.

[0006] As a further improvement, the feature is that the Teflon layer is coated with a frosted layer.

[0007] It prevents external friction and improves wear resistance. Smooth Teflon is very conspicuous when it gets dirty. With the frosted layer, even if there is a small amount of dust or oil, it will not have a big impact on the appearance.

[0008] As a further improvement, it is characterized in that: the Teflon layer is fastened with a buckle, the buckle is tightened, buckle interfaces are provided at both ends, screw holes are provided on the buckle interfaces, and they are connected with bolts.

[0009] The Teflon layer is made more secure by the buckle, which brings great benefits to production and processing. It is more convenient to use Teflon sheet material to wrap the inner layer of the metal conductor.

[0010] As a further improvement, it is characterized in that: the metal-plated layer is a tin-plated layer or a silver-plated layer.

[0011] A manufacturing process of the above-mentioned Teflon wire, the specific steps are as follows:

[0012] Step 1: Drawing the metal conductor to a length of 5 to 8 times the original length, then immersing it in the protective metal liquid for 5 to 15 minutes, and then drawing it again to a length of 5 to 8 times the original length, and repeating this three times to obtain a metal conductor containing a metal-plated layer;

[0013] Step 2: Make glue, take 10-30% concentrated nitric acid, 10-15% fluorine-containing solution, 3-5% defoamer, 6-8% leveling agent, and the balance is toluene, mix and stir to make glue;

[0014] Step 3: Apply the above glue on the inner surface of the Teflon material, then wrap the metal conductor in step 1, and cut off the excess Teflon material to form a Teflon layer;

[0015] Step 4: Place the Teflon layer initially pasted in step 3 into an oven at 300-350 degrees Celsius for 40-60 seconds, and form a Teflon wire after cooling.

[0016] As a further improvement, it is characterized in that: the metal conductor is copper, and the protective metal liquid is a silver-containing solvent.

[0017] As a further improvement, it is characterized in that: the fluorine-containing liquid is a silicon fluoride solution.

[0018] Beneficial effects of the present invention: The Teflon wire and its manufacturing process provided by the present invention can overcome the phenomenon that the metal conductor adheres to the inner surface of Teflon during the use of the wire, and the service life of the Teflon wire is extended.
