Problems solved by technology

For example, the formula is: SH-200 (PVC resin) 45-50 parts, TOTM (triisooctyl trimellitate plasticizer) about 35 parts, HD2500 (heavy calcium carbonate filler) 20-25 parts, Yingtian (Stabilizer) The PVC sheath material for headphone wires made from 2-3 parts of raw materials. Although the headphone wires made of this PVC sheath material have good softness, they are poor in oil corrosion resistance and soft and stable. Poor resistance, easy to be corroded by oil, resulting in thinner earphone cable, increased hardness, and lost the softness that the earphone cable should have

Abstract

The invention discloses an oil-proof PVC sheath material for earphone wire, which is obtained by evenly mixing and then, in a double screw extruder, extrusion-granulating the following raw materials, based on weight part, of: 45-50 parts of WS-1300, 25-35 parts of W-2050, 20-25 parts of mixed filler, 2-5 parts of YC-300 and 0.5-2.0 parts of LOCK, the mixed filler is formulated by HD-2500 and CCR-603 in accordance with weight ratio of 1:1-2; the sheath material is not liable to be extracted by organic solvent like oil product after being processed to the earphone wire, has preferable corrosive resistance to organic solvent like oil product, and still has good elasticity and softness after being immersed in organic solvent like oil product. Therefore, the invention is oil-proof PVC sheath material for earphone wire that has preferable oil product resistance and softness stability.

Description

technical field [0001] The invention relates to a cable sheath material, in particular to an oil-resistant PVC sheath material for earphone wires. Background technique [0002] The sheath material of the outermost layer of the cable is an important protective layer, which has properties such as sun resistance, radiation resistance, wear resistance, heat resistance, aging resistance, and chemical corrosion resistance; for example, the publication number is CN101407612A, and the publication date is April 2009 On the 15th, the name of the invention application is a soft thermoplastic sheath material for mobile power and control cables, and it is disclosed that it is composed of chlorinated polyethylene, silane coupling agent, polyethylene wax plasticizer, anti-aging agent, stabilizer, barrier The raw material formula composed of fuel and reinforcing agent is extruded and granulated by a screw extruder. At present, the commonly used raw material formulations for the production ...
