Problems solved by technology

[0003] At present, the wire materials of bright earphones are generally thermoplastic polyester elastomers TPEE, PVC, and polyurethane elastomers TPU. TPEE is expensive, PVC contains halogens and phthalates restricted substances, and TPU has poor processing performance, which limits their applications. At present, the largest amount of earphone wires is thermoplastic elastomer TPE, and TPE wires generally have a matte appearance due to the base material system. Some people brighten the color by increasing the processing temperature, but only a limited increase Brightness, in order to significantly improve the brightness, has become a problem that everyone in the industry is thinking about

Abstract

The invention relates to a non flame-retardant glossy elastomer material for a headphone cable and a preparation method of the elastomer material. The non flame-retardant glossy elastomer material for the headphone cable is characterized by consisting of the following raw materials in parts by weight: 20-50 parts of styrene-ethylene-butylene-styrene (SEBS) elastomer, 2-5 parts of butadiene rubber, 10-35 parts of polypropylene, 2-10 parts of fluidity improver, 20-50 parts of plasticizer, 12-25 parts of mineral filler, 0.5-2 parts of lubricant, 0.2-0.5 part of antioxidant and 0.2-0.5 part of ultraviolet light absorber. The non flame-retardant glossy elastomer material for the headphone cable disclosed by the invention is reasonable in various components and dosages thereof in the raw material formula, and integrates hand feeling, rebound, noise canceling, fidelity, service life and other comprehensive performances.

Description

technical field [0001] The invention relates to the field of polymer elastic body materials, in particular to a non-flame retardant bright surface elastic body earphone wire material and a preparation method thereof. Background technique [0002] With the rise of smart phones and tablet PCs, and the continuous hot sales of computers, multimedia players, CDs, MP3s and other products, earphones, as a mature electronic product, are more and more widely used. Since entering the 21st century, various The emergence of a fashion trend of thought has also prompted people's thinking to change. More and more fashion elements appear in the earphone cables, such as: transparent earphone cables, luminous earphone cables, multi-color earphone cables, etc. People's demand for products is getting higher and higher. More and more, on the premise of retaining the basic requirements of hand feel and sound quality, the requirements for appearance are also getting higher and higher. Various bran...
