preparation example Construction

[0031] In the present invention, there is no special limitation on the source of the polyimide fiber paper, and any preparation method known to those skilled in the art or commercially available products can be used. In the present invention, the polyimide fiber paper is preferably prepared by a method comprising the following steps:

[0032] The polyimide fibers are sheared and dispersed in an aqueous solution of sodium dodecylbenzene sulfonate, cleaned with deionized water; then put into a tank beater for beating, and fully decomposed and dispersed to obtain polyimide fibers. The amine fiber slurry uses a cellulose film as a substrate, sprays the polyimide fiber slurry on the substrate by high-pressure airless spraying, and peels off the substrate to obtain a polyimide fiber paper. In the present invention, there is no special limitation on the dosage and concentration of the polyimide fiber and sodium dodecylbenzenesulfonate aqueous solution, and the dosage well known to th...

Embodiment 1

[0053] The polyimide fibers are sheared and dispersed in an aqueous solution of sodium dodecylbenzene sulfonate, cleaned with deionized water; then put into a tank beater for beating, and fully decomposed and dispersed to obtain polyimide fibers. For the amine fiber slurry, the cellulose film is used as the substrate, and the polyimide fiber slurry is sprayed onto the substrate by high-pressure airless spraying, and the substrate is peeled off to obtain polyimide fiber paper (thickness is 1mm).

[0054] Using sodium dodecylsulfonate (SDBS) as a debonding agent, the para-aramid chopped fibers were dissolved in warm water at 30°C, stirred for 3 minutes to fully decompose, and then washed several times with deionized water before use. Among them, the mass ratio of sodium dodecyl sulfonate, para-aramid chopped fibers and warm water is 0.05:1:200.

[0055] Using polyethylene oxide (PEO) as a dispersant, the para-aramid pulp fiber was dissolved in deionized water, and stirred for 3 ...

Embodiment 2

[0063] The polyimide fibers are sheared and dispersed in an aqueous solution of sodium dodecylbenzene sulfonate, cleaned with deionized water; then put into a tank beater for beating, and fully decomposed and dispersed to obtain polyimide fibers. For the amine fiber slurry, the cellulose film is used as the substrate, and the polyimide fiber slurry is sprayed onto the substrate by high-pressure airless spraying, and the substrate is peeled off to obtain polyimide fiber paper (thickness is 0.05 mm).

[0064] Using sodium dodecylsulfonate (SDBS) as a debonding agent, the para-aramid chopped fibers were dissolved in warm water at 50°C, stirred for 5 minutes to fully decompose, and then washed several times with deionized water before use. Among them, the mass ratio of sodium dodecyl sulfonate, para-aramid chopped fibers and warm water is 0.1:1:300.

[0065] Using polyethylene oxide (PEO) as a dispersant, the para-aramid pulp fiber was dissolved in deionized water, and stirred for...

Abstract

The invention provides an anti-electromagnetic interference anti-breakage data line, belonging to the technical field of data lines. In the anti-electromagnetic interference anti-breakage data line, acarbon nanotube is a good electromagnetic shielding material, which has superior physicochemical and mechanical properties, and the excellent electromagnetic properties enable the material to exhibitgood electromagnetic shielding performance when the carbon nanotube is added into the composite material; Aramid fiber has high strength and toughness, and the carbon nanotube / aramid fiber conductivepaper has high strength, high toughness and a shielding effect, is an ideal data line coating layer material. The data of the data line provided by the embodiment shows that the anti-electromagneticinterference anti-breakage data line manufactured by the invention has electromagnetic shielding effectiveness of 39-46 dB in the frequency band of 175-1600 MHz, and can withstand bending tests for 5000-10000 times without obvious cracks.

Description

technical field [0001] The invention relates to the technical field of data lines, in particular to an anti-electromagnetic interference and anti-breakage data line. Background technique [0002] The data cable is used to connect mobile devices or computers to achieve data transmission or charging. Now, with the rapid development of the electronics industry, data cables have become an indispensable part of our lives. Due to the frequent use of data lines in daily life, the data lines are easy to break, and ordinary data lines can no longer meet the current needs. [0003] At the same time, today's data lines need to ensure the stability and security of the transmitted information, and they must have certain anti-electromagnetic interference, that is, shielding performance. The shielding layer currently used in the market, such as aluminum foil and braided mesh, is easily affected by external factors, and its shielding effect is particularly poor under the interference of s...
