[0016] The invention provides a preparation method of a waterproof cable, wherein the preparation method comprises:

[0017] 1) Soak mica powder and talc powder in dodecyl dimethyl tertiary amine and take them out to obtain particulate matter M1;

[0018] 2) roasting after mixing the above-mentioned particles M1, white carbon black and graphite, to obtain mixed particles M2;

[0019] 3) mixing and melting natural rubber, EPDM rubber, the above-mentioned mixed particles M2, paraffin, monoglyceride stearate, naphthenic oil and processing aids, and extruding to form a rubber sleeve;

[0020] 4) Stranding a plurality of silver-plated copper-clad steels to obtain a wire core;

[0021] 5) Wrap the wire core with the rubber sheath to make a waterproof cable.

[0022] In the present invention, mica powder and talc powder are soaked in dodecyl dimethyl tertiary amine, so that the specific surface area of ​​mica powder and talc powder etc. are modified to a certain extent, and then th...

Abstract

The invention discloses a waterproof cable and a preparation method thereof. The preparation method includes 1) immersing mica powder and talc powder in dodecyl dimethylamine to obtain a particulate matter M1; 2) mixing and roasting the particulate matter M1, white carbon black and graphite to obtain a mixed particulate matter M2; 3) mixing and smelting natural rubber, ethylene propylene diene rubber, the mixed particulate matter M2, paraffin, stearoyl-rac-glycerol, naphthenic oil and a processing aid and conducting extrusion formation to obtain a rubber sleeve; 4) stranding a plurality of silver-plated copper clad steel to obtain a cable core; 5) wrapping the cable core with the rubber sleeve to obtain the waterproof cable. The waterproof cable is waterproof, better in wear resistance andbetter in resistance to breakage.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a waterproof cable and a preparation method thereof. Background technique [0002] As we all know, cables, as a commonly used power facility, are used in a wide range of fields, and in actual use, they are often laid underground in order to prevent accidents caused by accidental contact by personnel. It is often too humid, and rain and other conditions will cause the moisture content in the soil to be too high, which will cause problems such as easy damage to the cable. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a waterproof cable with better waterproof performance, better wear resistance, and better anti-breakage and its preparation method. Contents of the invention [0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the problem that cables in the prior art are often laid underg...
