Special material for forming halogen-free high-flowability anti-yellowing wire rod and preparation method of material

Abstract

The invention discloses a special material for forming a halogen-free high-flowability anti-yellowing wire rod. The material is prepared from the following raw materials: SEBS (Styrene-Ethylene-Butylene-Styrene) rubber resin, a softening plasticizer, a polyolefin elastomer, functional resin, polypropylene resin, an antioxidant, a light stabilizer and a processing agent. The invention further discloses a preparation method of the special material for forming the wire rod. The special material for forming the wire rod has the advantages of no halogens, anti-yellowing property, good adhesiveness, high tensile strength, high flowability and easiness in injection molding, processing and forming and the like. As no halogens are available, the condition that harmful substances in the combusting and heating process are released to threat the physical health of human and environment is effectively avoided. The preparation method provided by the invention is concise in technical step and easy to realize, and can quickly prepare the special material product for forming the halogen-free high-flowability anti-yellowing wire rod. The product can be widely applied to other wire rod products such as external membranes of plugs of top grade earphone lines and external membranes of plugs of data lines, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of wire forming materials, in particular to a halogen-free, high-fluidity, anti-yellowing wire forming special material and a preparation method thereof. Background technique [0002] With the advent of the 3G 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, watch mobile TV, or listen to music. In order to obtain better sound quality, and in order not to affect others and keep their privacy to a certain extent, people generally choose to use earphones to implement the above activities. In addition, earphones have become an essential part of electronic products with sound such as mobile phones, computers and walkmans. [0003] The earphone generally includes an earphone cable and earplugs or hanging ears arranged at one or both ends of the earphone ...

AI Technical Summary

Problems solved by technology

The earphone cord covers in the prior art generally have disadvantages such as low elasticity, easy yellowing, and low tensile strength. Since the earphone cords often need to be folded or curled during use, after a period of use, the earphone cord covers will be worn out. It is easy to be damaged, broken, yellowed, peeled and other problems, making the conductor exposed, affecting the appearance of the earphone cable, and even affecting the sound quality of the earphone, affecting its normal use

Moreover, the existing earphone wires contain halogens, which will release harmful substances during combustion and heating, threatening human health and the environment.

In addition, the existing material of the outer cover of the earphone cable has poor fluidity, which is not conducive to the production of the earphone cable, and has a certain impact on the production efficiency and product quality.
