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...
