Abstract

The invention discloses a sealing element for a cable joint, a sealing element material formula and a preparation method, and relates to the technical field of cable accessories. The sealing element material formula for the cable joint comprises a sealing sleeve, a bulge pipe is arranged in the middle of the sealing sleeve, and a telescopic pipe is arranged on the bulge pipe; the sealing sleeve, the bulge pipe and the telescopic pipe are of an integrated structure, and a material formula used for producing the sealing element comprises natural rubber, sulfur, magnesium oxide, magnesium hydroxide, tridecafluorooctyltrimethoxysilane, trioctyl trimellitate, an anti-aging agent DPN1-2, bisphenol A and paraffin. The invention also provides a preparation method of the sealing element by using the sealing element material formula for the cable joint. The sealing element is flexible and convenient to use and good in sealing effect, has good hydrophobicity on the premise that it is guaranteed that the sealing element has good flexibility, elasticity, oxidation resistance, acid resistance and alkali resistance, the weather resistance of the sealing element can be effectively improved, and the service life of the sealing element is prolonged.

Description

technical field [0001] The invention belongs to the technical field of cable fittings, and in particular relates to a seal for cable joints, a material formula for the seal and a preparation method. Background technique [0002] Wires and cables are wires used to transmit electric energy. They are often composed of one or more wire cores and packaging materials outside the wire cores. The cables often encounter breakage during use, causing the cables to fail to transmit electric energy normally. At this time, the electrician will connect the broken part of the cable. The traditional connection method is to twist and twist the wire cores at the broken part, and then wrap the joint with waterproof tape. This method can easily lead to poor sealing of the tape. , The core twisted connection is exposed outside, on the one hand, it brings the risk of electric shock, and on the other hand, the exposed core is easily oxidized, resulting in an increase in the resistance of the connec...
