Embodiment 1

[0042] refer to figure 1 , this embodiment discloses a preparation process for an electric wire sheath, comprising the following steps:

[0043] S1: mixed sanding. The raw materials of the electric wire sheath were added into the pulverizer in no order according to the weight part and pulverized to 200 mesh. Then all the crushed materials are transported to the mixer for stirring, and the stirring speed is 900r / min, and the stirring is continued for 25min. The raw materials of the wire sheath are 65 parts by weight of polyvinyl chloride resin, 130 parts of calcium carbonate, 6 parts of quartz, 12 parts of carbon black, 33 parts of chlorinated paraffin and 8 parts of dioctyl phthalate.

[0044] S2: high temperature melting. Transport the material after S1 treatment to a high-temperature calciner, and heat the material in the high-temperature calciner to 700°C, and keep stirring at this temperature for 15 minutes, and then keep it warm for 50 minutes.

[0045] S3: Rubber vul...

Embodiment 2

[0050] The difference from Example 1 is that the raw materials of the electric wire sheath are different. The raw materials of the dot line skin are 65 parts by weight of polyvinyl chloride resin, 130 parts of calcium carbonate, 6 parts of quartz, 12 parts of carbon black, 33 parts of chlorinated paraffin, 8 parts of dioctyl phthalate and 50 parts of chlorinated rubber share.

Embodiment 3

[0052] The difference from Example 1 is that the raw materials of the electric wire sheath are different. The raw materials of the dot line skin are 65 parts by weight of polyvinyl chloride resin, 130 parts of calcium carbonate, 6 parts of quartz, 12 parts of carbon black, 33 parts of chlorinated paraffin, 8 parts of dioctyl phthalate, and 50 parts of chlorinated rubber. parts and 34 parts of nylon.

Abstract

The invention belongs to the technical field of wire production, and particularly discloses a wire sheath and a preparation process thereof. The wire sheath is prepared from the following raw materials in parts by weight: 50-80 parts of polyvinyl chloride resin, 100-160 parts of calcium carbonate, 3-8 parts of quartz, 8-16 parts of carbon black, 23-43 parts of chlorinated paraffin and 6-10 parts of dioctyl phthalate. The preparation process comprises the following steps of: S1, mixing and grinding; S2, high-temperature smelting; S3, rubber vulcanizing; S4, extrusion molding; S5, winding; and S5, obtaining the wire sheath after winding treatment. By adding a small amount of quartz into the polyvinyl chloride resin, the tensile strength of the finally obtained wire sheath can be improved. The dioctyl phthalate is a plasticizer, and when the polyvinyl chloride resin is selected as a main material of the wire sheath, the dioctyl phthalate can improve the performance of the polyvinyl chloride resin and improve the strength of the final wire sheath.

Description

technical field [0001] The present application relates to the technical field of wire production, in particular to a wire sheath and a preparation process thereof. Background technique [0002] Plastics for wire and cable insulation and sheathing are commonly known as cable materials, also known as wire sheaths; including rubber, plastic, nylon and other varieties. Except for bare wire products such as steel-cored aluminum stranded wire and electromagnetic wire, almost all wire and cable products require an insulation layer. The dotted skin is a particle prepared by kneading, kneading, and extruding with plastic and rubber materials as the base resin, adding stabilizers, plasticizers, inorganic fillers, additives, lubricants and other additives. Among them, the plastic material is mostly polyvinyl chloride, because of its light weight, flame retardancy, wear resistance, chemical corrosion resistance, excellent electrical insulation performance and high mechanical strength, ...
