Problems solved by technology

[0002] With the rise of Apple mobile phones, the demand for frosted mobile phone charger cables is increasing, but Apple mobile phone charger cables are usually made of thermoplastic polyester elastomer TPEE material, which has the disadvantages of high hardness, high price, and tearing. Poor strength, easy to absorb dust, etc. Thermoplastic elastomer (TPE) has the characteristics of good processing performance, delicate hand feeling, wide hardness range, and good flame retardancy. It is widely used in the field of consumer electronics, such as data cables, earphone cables, etc. Elastomer (TPE) used as a mobile phone charger cable has a smooth appearance, and no thermoplastic elastomer with a frosted feel has been reported so far.
[0003] In addition, the matte feeling of existing materials is often caused by adding additives such as sanding agents and sanding powders. The dispersion of particles in the main resin is not good, uneven, and the sanding effect is not good.

Abstract

The invention relates to the technical field of high polymer materials, and particularly discloses thermoplastic elastomer for a frosted-sense wire. The thermoplastic elastomer is prepared from, by weight, 15%-35% of styrene block copolymer, 10%-35% parts of dynamic vulcanized rubber TPV, 10%-25% of poly(ethylene-co-1,4-cyclohexylenedimethylene terephthalate) PCT, 6%-18% of polyolefin, 6%-14% of plasticizer, 5%-10% of polymethyl methacrylate, 5%-10% of poly aldehyde-acid vinyl ester, 3%-8% of fire retardant and 1%-3% of auxiliaries. The invention further discloses a preparation method of the thermoplastic elastomer for the frosted-sense wire. Compared with the prior art, the thermoplastic elastomer has the advantages of being good in frosted effect, good in resilience, low in cost, good in appearance, good in hand feeling and the like, and the comprehensive properties of good hardness, good strength, durability, shock resistance, tensile resistance and the like are achieved.
