Abstract

The invention discloses a corrosion-resistant insulated cable material and a preparation method thereof. The corrosion-resistant insulated cable material comprises the following raw materials in parts by weight: 70-90 parts of polyurethane rubber, 1-20 parts of a mica powder, 6-12 parts of nylon, 10-15 parts of alkali-free glass fiber yarn, 5-10 parts of dipropylene glycol dibenzoate, 5-10 parts of HRB-6 resin, 7-13 parts of magnesium hydroxide, 4-8 parts of aluminum hydroxide, 2-3 parts of tert-butyl peroxybenzoate, 1.5-2 parts of zinc oxide, 2-3 parts of stearic acid, 3-6 parts of chlorinated paraffin, 15-20 parts of fumed silica, 10-15 parts of nano attapulgite, 10-15 parts of precipitated barium sulfate, 1.5-2.5 parts of an antioxidant, 2-3 parts of an anti-aging agent TPPD, 3-6 parts of composite fillers, 1-2 parts of an accelerator ZDMC and 1-2 parts of an accelerator CZ. The cable material provided and prepared in the invention has high wear resistance, also has high heat resistance, high flame retardancy, high aging resistance, high oil resistance, high flexure resistance, high impact resistance and high tear resistance, is durable in use, and can fully meet performance requirements of modern wires and cables.

Description

technical field [0001] The invention belongs to the field of electric cable materials, and in particular relates to a corrosion-resistant insulating cable material and a preparation method thereof. Background technique [0002] Wires and cables mainly include bare wires, cloth wires and power cables for electrical equipment, cross-linked cables and communication optical cables. [0003] According to the operation analysis in recent years, especially in Pudong, Shanghai, where the economy is developing at a high speed, quite a lot of cable faults are caused by mechanical damage. For example, if the laying and installation of electric wires is not carried out according to the standard construction, it is easy to cause mechanical damage; if the civil construction is carried out on the direct buried cable, it is very easy to damage the running cable, etc. If the damage is not serious, it will take months or even years to cause damage. The damaged part is completely broken down ...
