preparation example Construction

[0031] The preparation method of composite base material, comprises the steps:

[0032] (1) In a water bath at 60~70°C, take multi-walled carbon nanotubes with a diameter of 10~30nm and add reagent A to mix at a mass ratio of 1:8~15, stir at 400~600r / min for 2~5h, and keep warm for 2~4h , filter, take the filter cake and mix it with hydrazine hydrate and deionized water according to the mass ratio of 3:1~2:15~20, heat and reflux at 60~75°C for 4~6h, filter with suction, take the filter residue and wash it with water for 3~5 times , dried in an oven at 100-110°C to constant weight to obtain pretreated carbon nanotubes;

[0033](2) Mix pretreated carbon nanotubes, tetrahydrofuran, and polyvinyl chloride according to the mass ratio of 2:10:3~5, and shear and disperse at 1000~2000r / min for 10~15min, then move to an ultrasonic oscillator, and use 55~ Ultrasonic treatment at a frequency of 65kHz for 10-15 minutes to obtain a dispersion, vacuum evaporation to obtain a concentrate, m...

Abstract

The invention discloses a wear-resistant cable sheath material, and belongs to the field of cable manufacturing. According to the wear-resistant cable sheath material, a multi-walled carbon nanotube is pretreated; nitrogen atoms are imported via hydrazine hydrate to change local charge density of the carbon nanotube; monoglyceride is taken as a raw material to undergo reaction with maleic anhydride; isooctyl alcohol is take as an end-capping reagent to control the molecular weight; the carbon nanotube is inserted into a mixture of components such as a composite binder, a modified phenolic resin and the like to greatly improve the wear resistance and toughness. When the phenolic resin is prepared, wear-resisting and toughening modification is carried out to ensure that normal-butyl is imported on the molecular chain of the phenolic resin, so that the cross-linking density is reduced, the toughness is improved, the dispersion capability and absorption capability, for impact energy, of the matrix are improved, and the toughness and wear resistance are increased. According to the wear-resistant cable sheath material, the problem of common cable sheath materials at present are bad in wear resistance and toughness is solved.

Description

technical field [0001] The invention belongs to the field of cable manufacturing, and in particular relates to a wear-resistant cable sheathing material. Background technique [0002] Wire and cable are the carriers of power transmission and information transmission, and are widely used in industrial and civil electrical facilities. Wires and cables are used in different environments or occasions and have different requirements, which puts forward higher requirements for the cable sheath covering the outside of the cable. The main function of the cable sheath is to mechanically and electrically protect the transmission cable from various conditions that will cause it to lose its transmission function. The cable jacket must fulfill this protective function during installation, splicing and throughout the service life of the cable. During the service life of the cable, the sheath must protect the cable core from moisture and other pollution. The degree of protection should k...
