技术领域technical field
本发明涉及数据传输线技术领域，尤其涉及一种具有金属光泽的数据线包覆材料及其制备方法。The invention relates to the technical field of data transmission lines, in particular to a data line covering material with metallic luster and a preparation method thereof.
背景技术Background technique
数据线的主要作用是数据传输、充电，其中有供数据传输、充电之用的芯线，这些芯线不能直接暴露在外，否则在使用的时候就会极不安全。为确保用户能够安全使用数据线，也为了保证数据线缠绕起来不容易被折断就要使用包覆层对芯线进行保护。目前市面上的数据线采用的包覆层多为TPE、PVC、编织线这三种材质。PVC价格比较经济，触感较好，但是使用时间长了以后容易出现爆皮和折断的现象。TPE与PVC相比，在热塑性、柔性以及弹性等方面更好，即便使用的时间较长也不容易发生折断。有些数据线的包覆层除了会使用TPE材料之外还会在其外包覆一层编织线，这层编织线多是用尼龙材料编织而成，使用之后可以让手机数据线的耐磨度以及抗拉扯能力都变得更强，但费用会较高。The main function of the data cable is data transmission and charging. There are core wires for data transmission and charging. These core wires cannot be directly exposed, otherwise it will be extremely unsafe when used. In order to ensure that the user can use the data cable safely, and to ensure that the data cable is not easily broken when it is wound, it is necessary to use a coating layer to protect the core wire. At present, the data cables on the market are mostly made of three materials: TPE, PVC, and braided wires. The price of PVC is relatively economical and the touch is good, but after a long time of use, it is prone to bursting and breaking. Compared with PVC, TPE is better in terms of thermoplasticity, flexibility and elasticity, and it is not easy to break even if it is used for a long time. In addition to using TPE material, the coating layer of some data cables will also be covered with a layer of braided wire. This layer of braided wire is mostly woven from nylon material, which can improve the wear resistance of the mobile phone data cable after use. And the resistance to pulling has become stronger, but the cost will be higher.
随着电子配件行业的发展，环保要求的日益严格，对于数据线的要求也越来越高，仅仅耐磨、不容易折断已经不能满足需求，因此开发出了一种不仅硬度耐磨度高、不易折断，而且环保、有金属光泽的数据线包覆材料及其制备方法。With the development of the electronic accessories industry, the environmental protection requirements are becoming more and more strict, and the requirements for data cables are also getting higher and higher.
