Problems solved by technology

[0004] However, the conventional TPE material is used to replace TPSiV as the wristband material for smart bracelets. It has the disadvantages of being slightly sticky, not smooth enough to be skin-friendly, and insufficient in wear resistance, which is not enough for the use of high-end smart bracelet wristband materials.

Abstract

The invention discloses a thermoplastic elastomer material for an intelligent wristband. The thermoplastic elastomer material is prepared from, by weight, 10-25 parts of styrene-ethylene-butene-styrene segmented copolymer, 5-10 parts of mineral oil, 35-65 parts of thermoplastic polyurethane, 5-8 parts of compatilizer, 15-30 parts of modified polysiloxane, 3-8 parts of mineral filler, 0.5-2 parts of lubricating agent and 0.1-0.5 part of antioxidant. The thermoplastic elastomer material has excellent abrasion resistance and a very remarkable internal and external lubricating effect, accordinglythe material surface obtains a smooth and slippery effect, the problem is solved that a TPE material is used for replacing TPSiV and serving as an intelligent wristband material and has sticky hand feel and insufficient smoothness, skin friendliness and abrasion resistance, and the use demand for high-end intelligent wristband materials is met.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a thermoplastic elastomer material for smart wristbands. Background technique [0002] In recent years, wearable devices, such as smart bracelets, smart bracelets for children's positioning, and smart watches, have become all the rage. Many of these wearable products use silicone or TPSiV as raw materials because of the skin-friendly, soft, and smooth requirements. [0003] At present, domestic smart wristband materials mainly include TPSIV, silica gel, TPU and TPE. Some brands of high-end smart bracelets use Dow Corning's TPSIV. TPSIV is praised by the industry as the preferred raw material for high-end smart bracelets. It has excellent performance and has the characteristics of vulcanized silicone rubber. It is a thermoplastic silicone elastomer that feels soft, skin-friendly and smooth. It can be injection molded and has excellent high temperature resistance Perfor...
