In this embodiment, the reinforcing agent is carbon black, the flame retardant is toluene-diphenyl phosphate, and the compatibilizer is maleic anhydride grafted compatibilizer.

[0027] The preparation method of the data line coating material in this embodiment includes the following steps:

[0028] (1) Mix TPV, add phthalocyanine blue, reinforcing agent, flame retardant, compatibilizer, metal powder in proportion and mix at 18°C ​​to obtain a mixture;

[0029] (2) After mixing the mixture evenly, add it to a twin-screw extruder, and carry out extrusion molding at 200°C.

[0030] Before the mixture is extruded, the molten mixture is molded with the data line and the charging line to obtain the mobile phone data line for performance...

Embodiment 3

[0032] The data line coating material of this embodiment includes, by weight, 93 parts of PVC, 0.6 parts of permanent violet, 0.7 parts of reinforcing agent, 0.7 parts of compatibilizer, and 9 parts of metal powder. In this embodiment, the reinforcing agent is carbon black, and the compatibilizer is a maleic anhydride grafted compatibilizer.

[0033] The preparation method of the data line coating material in this embodiment includes the following steps:

[0034] (1) Mix PVC, add permanent violet, reinforcing agent, compatibilizer and metal powder in proportion and mix at 20°C to obtain a mixture;

[0035] (2) After mixing the mixture evenly, add it to a twin-screw extruder, and carry out extrusion molding at 250°C.

[0036] Before the mixture is extruded, the molten mixture is molded with the data line and the charging line to obtain the mobile phone data line for performance testing.

Abstract

The invention provides a data line coating material and a preparation method thereof. The data line coating material comprises the following components in parts by weight: 85-98 parts of a carrier, 0.5-1 part of color masterbatch, 0.5-1 part of a compounding agent, 0.5-1 part of a compatilizer and 1-10 parts of metal powder. The preparation method of the data line coating material comprises the following steps: (1) mixing the carrier, adding the color master batch, the compounding agent, the compatilizer and the metal powder in proportion, and carrying out mixing to obtain a mixture; and (2) uniformly mixing the mixture, adding the mixture into a double-screw extruder, and carrying out extrusion molding. The data line coating material has metal luster and a good appearance effect; and through the addition of metal powder, the use of the color masterbatch is reduced, the surface hardness of the coating material is increased, and the data line is prevented from being scratched in the useprocess.

Description

technical field [0001] The invention relates to the technical field of data transmission lines, in particular to a data line coating material with metallic luster and a preparation method thereof. Background technique [0002] The main function of the data line is data transmission and charging, and 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 users can use the data cable safely, and to ensure that the data cable is not easy to be broken when it is wound, it is necessary to use a coating to protect the core wire. At present, the data cables on the market are mostly made of three materials: TPE, PVC, and braided wire. The price of PVC is relatively economical, and the touch is good, but after a long time of use, it is prone to cracking and breaking. Compared with PVC, TPE is better in terms of thermoplasticity, flexibility and elasticity, and it ...
