Abstract

The invention discloses a preparation method for a milk silky fiber headphone cable. The method is characterized by comprising the following steps of (1) weighing the following components in parts by weight: 0-50 parts of polystyrene, 10-20 parts of styrene-ethylene-butadiene-styrene copolymer grafted maleic anhydride, 30-40 parts of polypropylene resin, 5-10 parts of polyolefin elastomer, 10-15 parts of milk protein composition fiber, 1-3 parts of paraffin, 0.5-1 part of antioxidant and 0.5-1 part of light stabilizer; (2) preparing powder, and then fully mixing the powder to obtain a mixture; (3) performing fusion mixing at the temperature of 300 DEG C, performing extrusion through an extruder, and performing cooling and drying to obtain a milk silky fiber headphone cable coat material; (4) forming the milk silky fiber headphone cable coat material into a coat of a headphone cable core wire, and preparing the milk silky fiber headphone cable with an elastic wrapping layer. The invention further discloses the milk silky fiber headphone cable prepared by virtue of the method. By optimizing the coat material formula and the internal structure of the headphone cable, the milk silky fiber headphone cable has the characteristics of being snowy white, skin-friendly, soft, tension-resistant and the like.

Description

technical field

[0001] The invention relates to the preparation technology of earphone wires, in particular to a preparation method and products of milk silky fiber earphone wires. Background technique

[0002] The traditional earphone cable covers generally have disadvantages such as low elasticity, easy yellowing, weak copper damage resistance and low tensile strength. Since the earphone cable often needs to be folded or curled during use, after a period of use, the earphone cable The outer cover is easy to be damaged, broken, yellowed, peeled and other problems, so that the conductors are exposed, affecting the appearance of the earphone cable, and even affecting the sound quality of the earphone, affecting its normal use. Moreover, the texture of the earphone cable jacket is an important condition for the quality of the earphone cable, because it is very necessary to develop a milk-like silky and skin-friendly earphone cable jacket material and make it into an earphone c...
