Problems solved by technology

[0003] Currently commonly used thermoplastic elastomers (Thermoplastic Elastomer, TPE) for the production of earphone cables and data cables generally contain mineral oils such as paraffin oil or naphthenic oil. During the use of the product, it is easy to cause yellowing of the wire, and the surface is sticky, vacuumed, and precipitated. , is not resistant to dirt, does not have a dry feel, and cannot meet the increasingly stringent requirements of consumers

preparation example Construction

[0031] A method for preparing a thermoplastic elastomer material for a signal transmission line in an embodiment includes the following steps:

[0032] Step 1, adding 15 to 25 parts by weight of SEBS, 7 to 15 parts by weight of polypropylene, 10 to 40 parts by weight of POE, 10 to 40 parts by weight of MLLDPE, 10 to 20 parts by weight of mineral fillers, 1-2 parts by weight of lubricant and 0.2-0.3 parts by weight of antioxidant are stirred and mixed at a speed of 1000-1400 rpm for 5-10 minutes to obtain a premix; and

[0033] Step 2, placing the premixed material in a twin-screw extruder to extrude, draw, cool, and granulate to obtain a thermoplastic elastomer material for signal transmission lines.

[0034] Preferably, the extrusion temperature of the twin-screw extruder is 170-200°C.

[0035] The above-mentioned preparation method of the thermoplastic elastomer material for the signal transmission line has a simple process flow, low requirements on equipment, and is suitab...

Abstract

The invention relates to a TPE (thermoplastic elastomer) material for a signal transmission line and a preparation method of the TPE material. The TPE material for the signal transmission line comprises components in parts by weight as follows: 15-25 parts of SEBS (styrene-ethylene-butylene-styrene), 7-15 parts of polypropylene, 10-40 parts of polyolefin elastomer, 10-40 parts of metallocene polyethylene, 10-20 parts of mineral filler, 1-2 parts of a lubricant and 0.2-0.3 parts of an antioxidant, wherein the TPE material for the signal transmission line does not contain paraffin oil. Compared with a traditional TPE material system for wire materials, the TPE material is free of mineral oil and avoids an oil outlet phenomenon, the prepared elastomer material is easy to extrude at low temperature, and further, the extruded wire material is not prone to yellowing, has smooth hand feeling and dry and clean surface and is not sticky and dust-adsorbing.

Description

technical field [0001] The invention relates to a thermoplastic elastomer material, in particular to a thermoplastic elastomer material for manufacturing signal transmission lines and a preparation method thereof. Background technique [0002] With the development of the wire industry, consumers pay more and more attention to the performance and appearance of data cables, and their requirements are getting higher and higher. Especially for signal transmission lines such as earphone cables and charging cables, it is required to feel smooth, dirt-resistant, and dust-free. Therefore, when producing earphone cables and data cables, the selection of materials is becoming more and more stringent. [0003] Currently commonly used thermoplastic elastomers (Thermoplastic Elastomer, TPE) for the production of earphone cables and data cables generally contain mineral oils such as paraffin oil or naphthenic oil. During the use of the product, it is easy to cause yellowing of the cable,...
