Problems solved by technology

So far, the vast majority of cable casings in China are filled with ointment, and the filling ointment is in direct contact with the cable, so the quality of the ointment directly affects the quality of the cable, and my country's research on ointment for cables The development is late, so there are still some defects, which need to be further improved

Abstract

The invention discloses a novel cable filler material. The cable filler material is prepared from, by weight, 50-80 parts of linear low density polyethylene plastic, 30-40 parts of epoxy resin, 5-10 parts of graphite, 1-8 parts of foaming agent, 2-6 parts of flame retardant, 1- 6 parts of stearic acid, 2-6 parts of modified nano-kaolin powder, 15-30 parts of bentonite, 5-15 parts of mineral powder, 3-9 parts of glass fiber, 1-3 parts of antimony trioxide, 2-4 parts of organic fibers, 1-3 parts of ethylene glycol, 2-3 parts of lead silicate and 3-8 parts of bluestone powder. The cable filler material has a good waterproof and moisture proof effect, good flame retardant performance, good stability and a good protection effect on cables.

Description

technical field [0001] The invention relates to a novel cable filling material. Background technique [0002] The filling material is used for filling, because the core of the cable is composed of multiple insulated cores twisted, and there will inevitably be gaps during the cable forming process. If these gaps are not filled with materials, the core of the cable will be unstable. ground, reducing the life of the cable during use. The filling material of the cable can ensure the roundness of the cable and avoid the twisted shape on the surface of the cable when the sheath is extruded, which is to reduce the excessive use of the sheath material during the extrusion process of the cable sheath and control the cost reasonably. So far, the vast majority of cable casings in China are filled with ointment, and the filling ointment is in direct contact with the cable, so the quality of the ointment directly affects the quality of the cable, and my country's research on ointment fo...
