Modified attapulgite reinforced cable sheath material

Abstract

The invention discloses a modified attapulgite reinforced cable sheath material. The modified attapulgite reinforced cable sheath material is prepared from, by weight, 30-50 parts of NBR-2707 type butadiene-acrylonitrile rubber, 50-70 parts of SBR-1502 type emulsion polymerized butadiene styrene rubber, 1-2 parts of stearic acid, 2-4 parts of N, N-meta phenylene bismaleimide, 0.5-2 parts of N-cyclohexyl-2-benzothiazole sulfenamide, 1-2 parts of zinc diethyldithiocarbamic acid, 2-6 parts of paraffin, 0.5-1.5 parts of antiager DPPD, 3-8 parts of nano-hydroxyapatite powder, 4-8 parts of enhancer DH-2, 15-25 parts of semi-reinforcement carbon black and 10-20 parts of modified attapulgite. The modified attapulgite reinforced cable sheath material has excellent processability and mechanical strength, and is simple in processing process, high in practicality and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of cable processing materials, in particular to a modified attapulgite-reinforced sheath material for external use of cables. 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 poll...

AI Technical Summary

Problems solved by technology

During the service life of the cable, the sheath must protect the cable core from moisture and other pollution. The degree of protection should keep the circuit performance in the cable core normal. Once too much moisture or other pollutants enter the cable core, the transmission performance will be affected. will seriously deteriorate

This requires the cable sheath to have high mechanical strength and internal toughness to prevent cracking or damage in harsh environments, resulting in abnormal cable transmission or potential safety hazards

[0003] Due to the particularity of the cable use environment, it is required that the cable sheath not only has good flame retardancy but also can withstand a changeable environment, otherwise the performance of the cable material will change in one way or another, and even lose its use value.

Therefore, if the protective sheath material does not have good mechanical strength, no matter how good other properties are, it cannot achieve good practicality.
