Problems solved by technology

[0003] At present, the high-transparency headphone cable materials on the market are generally made of PVC or TPU, and both PVC and TPU have obvious defects of poor weather resistance and soft hand feeling.
However, the transparency of the wire made of general thermoplastic elastomer is not as good as PVC and TPU, and the surface smoothness is not as good as PVC and TPU.

Embodiment 1

[0024] This embodiment discloses a thermoplastic elastomer raw material, the thermoplastic elastomer raw material is used to manufacture high-transparency earphone wires, and the earphone wires using the thermoplastic elastomer raw material have the characteristics of high transparency, soft and smooth feel.

[0025] Its components include: hydrogenated styrene-butadiene block copolymer, softening oil, polypropylene resin, propylene-based elastomer and lubricating aid, and it is characterized in that, based on the sum of the weights of the above-mentioned components, each of them The group distribution ratio is:

[0026]

[0027]

[0028] The hydrogenated styrene-butadiene block copolymer (styrene-butadienetriblockcopolymer, referred to as: SBS) is a white loose columnar solid, chemical characteristics: the relative molecular weight of SEBS has a great influence on the performance, the relative molecular weight is large, and the solution viscosity is large , High bonding...

Embodiment 2

[0034] See figure 1 , figure 1 It is a flowchart of a manufacturing method for a thermoplastic elastomer raw material used for earphone wires disclosed in this embodiment. figure 1 A manufacturing method of a thermoplastic elastomer raw material is shown, which is used to manufacture thermoplastic elastomer raw materials for manufacturing earphone wires. The earphone wires using the thermoplastic elastomer raw materials not only have high transparency, but also have fine and soft touch and weather resistance Strong features.

[0035] Such as figure 1 As shown, the manufacturing method includes the following steps:

[0036] S1. Stir the hydrogenated styrene-butadiene block copolymer evenly in a high-speed mixing tank, and stir until warmed to 60-70 degrees Celsius, add the softened oil several times according to a certain proportion and stir, and finally add Stir the softened oil for 10 minutes until fully absorbed;

[0037] S2, placing the mixture obtained in the step S1 ...

Abstract

The invention discloses a thermoplastic elastomer raw material for an earphone cable. The thermoplastic elastomer raw material is used for manufacturing the earphone cable and comprises, by weight, 30-40% of a hydrogenated styrene-butadiene block copolymer, 20-30% of softening oil, 10-15% of polypropylene resin, 5-10% of propenyl elastomer and 1-2% of a lubrication additive, wherein the sum of the weight ratios is a cardinal number. The high-transparency earphone cable is manufactured through the thermoplastic elastomer raw material, on the basis of keeping the consistent advantages of high elasticity, weather resistance, fatigue resistance and the like of the thermoplastic elastomer raw material, the earphone cable further has the advantages of high transparency, soft hand feeling and good smoothness, meanwhile, the manufacturing technology is easy to implement, practical production and machining are economical, convenient and fast, and the industrial application prospect is good.

Description

technical field [0001] The invention relates to the field of chemical raw materials, in particular to a thermoplastic elastomer raw material used for earphone wires, a manufacturing method thereof and its application in the manufacture of high-transparency earphone wires. Background technique [0002] Thermoplastic elastomer raw material, the English name is ThermoPlasticElastomer (TPE for short) or ThermoPlasticRubber (TPR for short), is a material with high elasticity, high strength, high resilience of rubber, and can be processed by injection molding. Compared with traditional thermosetting rubber, thermoplastic elastomers have many advantages such as simple molding and processing, reusable materials, high cost performance, less environmental pollution, superior processing performance, no need for vulcanization, and can be recycled to reduce costs. Molding, coating and bonding with PP, PE, PC, PS, ABS and other base materials, or molding alone, thermoplastic elastomers ha...
