Abstract

The invention relates to the field of polymer materials, in particular to a polyester elastomer-based neck hanging line shaping material as well as a preparation method and application thereof. The material is prepared from the following raw materials in parts by weight: 50-70 parts of polyester elastomer, 15-25 parts of TPU, 10-25 parts of polyolefin elastomer, 3-5 parts of a compatilizer, 1-3 parts of a lubricant and 3-4 parts of an assistant. According to the material, the TPU and the polyolefin elastomer are introduced for polymerization, the compatibility of the materials is improved under the action of the compatilizer, the flexibility and toughness of the shaping material are improved by introducing the TPU, and the resilience and impact resistance of the shaping material are improved by combining the polyolefin elastomer; and the shaping material prepared after polymerization can be prepared and molded in a low-temperature environment, so that the preparation difficulty and theenergy consumption cost are reduced, and the product is good in rebound resilience, not liable to deform, high in breaking strength, high in impact strength and not liable to break.

Description

technical field [0001] The invention relates to the field of polymer materials, more specifically, it relates to a polyester elastomer-based hanging neck thread setting material and its preparation method and application. Background technique [0002] The existing earphones are divided into wired and wireless. The two wired earphones are connected by a cable; The connection of the transmitting device requires two separate earphones to be equipped with a Bluetooth unit and an independent battery, but the technology is difficult, the cost is high, and it is easy to drop a single earphone, so that the entire pair of earphones cannot be used in pairs. In this regard, in order to achieve a better wearing effect, the current wireless Bluetooth headset generally adopts a hanging neck structure to improve its stable connection structure and avoid falling; but in actual use, the connection between the hanging neck line and the headset is easy Fracture will affect the service life of...
