Problems solved by technology

The injection molded parts of the earphones in the prior art generally have disadvantages such as low elasticity, easy yellowing, poor fluidity, and easy to stick to dust. Since the earphone wires often need to be folded or curled during use, after a period of use, the injection molded parts of the earphone wires It is easy to be damaged, yellowed, separated from the outside of the earphone cable, and sticky to dust, etc., which will affect the appearance of the earphone cable, even affect the sound quality of the earphone, and affect its normal use.
Moreover, the existing headphone cable injection molding materials contain halogen and have no flame retardants, which are easy to ignite during use and release harmful substances during combustion, threatening human health.
In addition, the existing earphone cable outer film material has poor fluidity, which is not conducive to the production of earphone cables, and has a certain impact on production efficiency and product quality.

Abstract

The invention discloses a special halogen-free anti-static flame-retardant material for TPE (thermal plastic elastomer) molding. The special halogen-free anti-static flame-retardant material comprises the following raw materials: SEBS (styrene-ethylene-butadiene-styrene) rubber resin, a softening plasticizer, a flame retardant, an anti-static agent, polypropylene resin, an antioxidant, a light stabilizer and a processing aid. The invention further discloses a preparation method for the special halogen-free anti-static flame-retardant material. The preparation method is simple in process step and easy to realize, and can be used for quickly preparing the special halogen-free anti-static flame-retardant material product for TPE molding. The special halogen-free anti-static flame-retardant material for TPE molding is reasonable in formula, has the advantages of no halogen, yellowing resistance, good flame resistance, good adhesion property, high fluidity, difficulty for dust adhesion, easiness for injection molding and the like, effectively avoids release of harmful substances in a heating process due to no halogen and flame resistance, cannot threaten human health or environment, and can be widely applied to an outer film of a high-grade headphone wire plug, an outer film of a data wire plug and other wire products.

Description

technical field [0001] The invention relates to the technical field of TPE molding materials, in particular to a special halogen-free antistatic flame retardant TPE molding material and a preparation method thereof. Background technique [0002] With the advent of the 4G era and the continuous improvement of people's living standards, people's lifestyles are becoming more and more diversified. Nowadays, when people are traveling or relaxing at home, they often make video calls, play games or listen to music. In order to obtain better sound quality and keep their privacy without affecting others, people generally choose to use earphones. Therefore, earphones have become an essential part of audio electronic products such as mobile phones and walkmans. [0003] The earphone generally includes an earphone cable and earplugs or hanging ears arranged at one or both ends of the earphone cable. Among them, the earphone cable generally includes conductors, bulletproof wires, jacke...
