Abstract

The invention relates to the field of an electric wire, particularly to a multi-strand tin-plated copper stranded wire. The multi-strand tin-plated copper stranded wire comprises a conductor formed by a bunch of multi-strand tin-plated copper stranded wires which are obtained from a plurality of tin-plated copper wires in a stranding manner; the outer surface of the conductor is coated with an inorganic particle granule layer, an insulating paint layer and a wear-resisting insulating layer in sequence; the wear-resisting insulating layer is a nylon surface layer or a high-temperature-resistant insulating layer immersed with epoxy resin; and the insulating layer comprises the components of PVC, PE, TPU and TPE. The smaller the wire diameter is, the higher the flexibility of the wire becomes; when multiple of the tin-plated copper stranded wires are stranded together, the tensile force of the wire is greatly improved, and conductor resistance is lowered; and meanwhile, by adding different fillers, the tensile force of the overall strand of the wire is improved, thereby satisfying different requirements.

Multiply multiply tin-coated copper strand production process, comprises the following steps：
Step one：Prepare blank and test material, whether in the margin of tolerance, whether inspection blank outward appearance has inspection billet size Oxidation, burr, the defect of crackle, will check blank that is qualified and temporarily not processing to be stored；
Step 2：Wire drawing, is stretched to a diameter of final wire rod straight using 450 meters to 550 meters speed per minute by blank The wire rod of 3-5 times of footpath,
Step 3：The wire rod of Jing step 2 process is carried out into electrotinning PROCESS FOR TREATMENT；
Step 4：Annealing, using 22 amperes to 28 amperes of electric current, 25 volts to 27 volts of voltage and by 22m/min The speed wire rod that processes Jing step 3 be sent into anneal, 570 DEG C of annealing furnace upper strata temperature, 580 DEG C of lower floor's temperature；
Step 5：Cooling cleaning, the wire rod processed through step 4 is cooled down and cleaned, and wire rod is dried to after cleaning Surface no liquid residual；
Step 6：Wire rod through step 5 is placed with the organosol of inorganic particles, sticks wire surface patch There are inorganic particles, inorganic particles inside has hollow or Porous, and the average grain diameter of inorganic particles is below 50nm；
Step 7：The some wire rods through step 6 process are twisted into a branch of multiply tin-coated copper using accurate wire twisting machine Twisted wire；
Step 8：Insulating barrier is applied, the wire rod processed through step 7 is carried out into PVC, PE, TPU, TPE insulation processing.
Step 9：Nylon or Furtulon high temperature tree in the wire surface coating epoxy resin-impregnated processed through step 8 Fat；
Step 10：Take-up, the multilayer insulated wire made is wound on the disk of client's defined tool, facilitates making for client With.
Wherein, described inorganic particles are metal oxide microparticle or Si oxide particulate.
The beneficial effects of the present invention is：Line footpath of the present invention is less, and flexibility is better, and a plurality of line is twisted together, significantly Its pulling force is improved, conductor resistance is reduced, while improving the pulling force of whole strand material by adding different fillers, meets different Demand so that multilayer insulated wire keeps good state under larger twisting power and extruding force；The reasonable adjusting of takeup tension, i.e., Takeup tension is controlled in 8～12g, so as to make the enamel-covered wire with low pitch, high density and high-flexibility, after stranded Single line elongation can reach more than 20%, while the pinhole number of whole stock enamel-covered wire is less than 10 in 5 meters after stranded.The present invention By drawing process production (0.05-3.0mm) any specification product, such as earphone cord, horn wire, LED copper wire lamp strings are used primarily in Luminous shoe lamp, timbo lamp, outdoor contour strength applications are made into different face using imported polyurethane insulating varnish and high-temperature color accurate adjustment The insulated paint of color, then by baking finish process, the enamel-covered wire of any color is produced, bright in luster, beautiful, good weatherability, color and luster is steady It is fixed, it is not easy to change；Sticking wire surface patch has inorganic particles, and inorganic insulation particle to enamel-covered wire except giving resistant to partial discharges Outside property, reduction, the raising of intensity of raising, the thermal expansion of pyroconductivity are additionally aided, high heat burnout is prevented, simultaneously because line Material surface has irregular projection, makes nylon surface layer and insulated paint have stronger adhesive force.Insulating properties of the present invention are projected, Stickiness is high, adhesive force that can be stronger, can meet performance requirement of the market to wire enamel.
