preparation example 1-3
[0044] As shown in Table 1, the main difference of Preparation Examples 1-3 is that the raw materials are different.
[0045] The following takes Preparation Example 1 as an example for illustration.
[0046] A kind of grafting aid, adopt following steps to prepare: According to proportioning, put dialkyl peroxide initiator and caprolactam into agitator, under the stirring speed of 160r / min, stir 5min, obtain grafting aid .

[0048]
preparation example 4
[0050] A kind of diphenylamine anti-aging agent, adopts following steps to prepare:
[0051] S1. According to the proportioning ratio, add 12.5kg of 4-aminodiphenylamine, 50kg of methyl isoamyl ketone and 0.65kg of Pd / C catalyst into the reactor in sequence, and stir for 10min at 140r / min to obtain a mixture;
[0052] S2, feed nitrogen into the reactor for 2 minutes, then feed hydrogen for 2 minutes, adjust the air pressure in the reactor to 3.5 MPa, then raise the temperature of the reactor to 140° C., and keep the temperature and pressure for 3 hours to obtain the reaction product;
[0053] S3, filter the reaction product, remove the Pd / C catalyst in the reaction product, obtain the filtrate, distill the filtrate at 100°C, stop the distillation when the mass fraction of the filtrate is 98.5%, and obtain the diphenylamine anti-aging agent.
preparation example 5
[0055] The difference between this preparation example and preparation example 4 is that in the step S2, the temperature of the reaction kettle is raised to 160°C.

Abstract
The application relates to the technical field of communication transmission equipment, and specifically discloses a high swing data line and a preparation method thereof. The high-swing data line includes a conductive wire core covered with a high-swing TPE material, and the high-swing TPE material is made of raw materials including the following parts by weight: 20-40 parts of SEBS elastomer, 10 parts of polypropylene ‑20 parts, 5‑10 parts of calcium carbonate, 5‑10 parts of maleic anhydride, 2‑4 parts of grafting aid, 3‑5 parts of anti-wrinkle agent; its preparation method is: high swing TPE material is melt-extruded, and then Wrapped on the conductive wire core, weld the conductive wire core with the USB connector and the transmission connector, and then inject molding with high swing TPE material to obtain a high swing data cable. The high swing data line of the present application has good tensile strength, elongation at break and tear strength, and is not easy to crack; in addition, the preparation method of the present application is easy to operate, which helps to further reduce the breakage of the high swing data line.
Description
technical field [0001] The present application relates to the technical field of communication transmission equipment, and more specifically, it relates to a high swing data line and a preparation method thereof. Background technique [0002] The data cable is a common structure used for data transmission. The data cable generally includes a conductive core and an outer sheath wrapped around the outer surface of the core. The outer sheath can reduce the damage of the core and reduce the electric shock of the user. [0003] Currently commonly used outer sheaths for data cables are generally made of TPE material. This kind of data cable outer sheath has good insulation performance, but it is not easy to be demolded during the manufacturing process. Related technology CN111391275A discloses a modified TPE material production process and modified TPE material. The main raw materials of the modified TPE material are: SEBS: 15%-25%, white oil: 15%-25%, polyurethane: 45%- 60%, pol...
