Embodiment 1

[0020] Example 1, a manufacturing method of a high-performance environmentally friendly home improvement wire, including the steps of wire drawing, co-extrusion, testing, coiling and warehousing, adopts copper single wire or stranded wire with a purity greater than 99.98% as the core material, and the surface insulation material includes inner Layer insulation material and outer layer insulation material, inner layer insulation material and outer layer insulation material are all PVC insulation materials, PVC insulation material is composed of 100kg polyvinyl chloride, 35kg p-phenylene, 5kg liquid calcium zinc stabilizer, 8kg kaolin, 20kg calcium It is composed of powder, and the outer insulating material is added with 1kg of pigment.

[0021] Wire drawing is carried out by continuous drawing and annealing of the copper rod, after multiple passes of drawing; the drawing speed of the last drawing is 1200m / min; or the stranding process is carried out to form a copper stranded wir...

Embodiment 2

[0026] Embodiment 2, the difference between this embodiment and embodiment 1 is that the PVC insulating material is composed of 100kg polyvinyl chloride, 42kg p-phenylene, 7kg liquid calcium zinc stabilizer, 11kg kaolin, and 28kg calcium powder, and the outer insulating material is increased by 1.5 kg of pigment, the temperature in the middle section of the extruder is about 150°C during co-extrusion, and the temperature at the head is about 175°C.

Embodiment 3

[0027] Embodiment 3, the difference between this embodiment and embodiment 1 is that the PVC insulating material is composed of 100kg polyvinyl chloride, 48kg p-phenylene, 8kg liquid calcium zinc stabilizer, 15kg kaolin, and 35kg calcium powder, and the outer insulating material is increased by 1.5 kg of pigment, the temperature in the middle section of the extruder is about 165°C during co-extrusion, and the temperature at the head is about 180°C.

[0028] The calcium powder that adopts in the above-mentioned embodiment is that heavy calcium carbonate and light calcium carbonate form by the ratio of mass ratio 2:1. Heavy calcium carbonate, referred to as heavy calcium, is ground from natural carbonate minerals such as calcite, marble, and limestone. Light calcium carbonate, also known as precipitated calcium carbonate, referred to as light calcium, is to burn limestone and other raw materials to produce lime and carbon dioxide, then add water to digest the lime to produce mil...

Abstract

The invention discloses a manufacturing method of a high-performance environment-friendly domestic wire. The method comprises the steps of wiredrawing, twisting, co-extruding, detecting, looping, warehousing, and the like. A high purity copper single wire is adopted as a core material, and the core material, an inner-layer uncolored insulating material and an outer-layer colorful insulating material are formed through co-extruding in a mode that three extruders share one machine head after wiredrawing, twisting and forming. The insulating materials adopt a PVC insulating material, the inner and outer layer materials are manufactured through a new raw material ratio and heat stabilizer, and hazardous substances of lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr<6+>), polybrominated diphenyl ethers (PBDE), polybrominated biphenyls (PBB) and the like are not contained, which is more environmentally friendly. According to the manufacturing method of the high-performance environment-friendly domestic wire, the formed wire core material is high in purity, high in overload capacity, low in electricity consumption, good in integrity of the double-layer co-extruding insulating material, good in overall performance, good in insulating performance and free from hazardous substances of lead, chromium and the like, and the requirements of the European Union RoHS environmental directive are met in the environmental protection aspect.

Description

technical field [0001] The invention relates to the field of electric wire manufacturing, in particular to a method for manufacturing high-performance environment-friendly home decoration electric wires. Background technique [0002] PVC wire and cable insulation and sheath materials are relatively cheap, with excellent mechanical properties and easy processing, making it the most widely used material in the wire and cable industry for a long time. Ordinary home improvement wires generally use ordinary round copper single wires as conductive cores, and ordinary PVC insulating plastics as single-layer insulation extruded to form home improvement wires. It has many advantages as well as its disadvantages: [0003] 1. The purity of the copper single wire used in the core material is usually 99.95%, which is not very high, so that the overload capacity of the wire is not strong, and the power consumption is relatively high. [0004] 2. Ordinary PVC insulating materials are mai...
