High-performance anti-deformation cable filling material

Abstract

The invention discloses a high-performance anti-deformation cable filling material which is prepared from the following ingredients in parts by weight: 55 to 75 parts of polycarbamate, 35 to 55 partsof phenolic resin, 10 to 18 parts of calcium stearate, 13 to 20 parts of titanium dioxide nanopowder, 15 to 25 parts of polyethylene, 7 to 12 parts of lithium-based enhancing powder, 10 to 15 parts ofquartz powder, 2 to 6 parts of epoxypropane glycerinum, 5 to 11 parts of aluminum hydroxide, 6 to 12 parts of magnesium hydroxide, 3 to 8 parts of antimonous oxide and 10 to 15 parts of compound filler. The cable filling material disclosed by the invention has the advantages of environmental friendliness, good flame retardation, high temperature resistance, low smoke, easiness in being peeledeasypeel, good compatibility, high strength, bending resistance, high anti-deformation strength and excellent corrosion resistance and flexibility. The cable filling material not only has an effective protecting effect on cables, but also can enhance tensile resistance of the whole cable.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a high-performance anti-deformation cable filling material. Background technique [0002] At present, with the development of social economy, the amount of wire and cable is increasing rapidly. The basic structure of power cable consists of four parts: core (conductor), filling layer, insulating layer, shielding layer and outer sheath. The core is the conductive part of the power cable, which is used to transmit electric energy and is the main part of the power cable. The insulating layer is to electrically isolate the wire core from the ground and the wire cores of different phases to ensure the transmission of electric energy. It is an indispensable part of the power cable structure. 15KV and above power cables generally have a conductor shielding layer and an insulating shielding layer. The cable is generally protected by a filling layer on the core. The function...

Problems solved by technology

[0003] The role of filling materials is particularly important in the use of cables. In the prior art, the protective effect of power cable filling layer materials is often not ideal, and the comprehensive function is poor, which needs to be improved.
