Problems solved by technology

[0002] In the long-term operation of power cables, it is easy to accumulate heat and cause fires. The main factor causing death in fires is not the direct combustion of flames, but the smoke generated when materials are burned. These smokes not only produce a large amount of toxic substances, but also can This is the main cause of death due to fire, and most of the existing power cable materials will produce a lot of smoke and toxic substances when burned, and these are mostly organic polymers, which are easy to burn, so in the event of a fire fueled the fire and caused more damage

Abstract

The invention discloses a cable material for electric thermal insulation, insulation and flame retardance and a preparation method thereof. The cable material comprises 30-40 parts of polyvinyl chloride (PVC), 20-35 parts of kieselguhr, 20-35 parts of magnesium hydrate, 10-15 parts of orthophthalic, 10-20 parts of ethylene propylene rubber, 15-30 parts of mixed resin, 20-30 parts of melamine cyanurate, 1-2 parts of stearic acid, 5-10 parts of dioctyl phthalate and 1-10 parts of polyethylene glycol. By scientifically matching and combining PVC, kieselguhr, magnesium hydrate, orthophthalic, ethylene propylene rubber, mixed resin, melamine cyanurate, stearic acid, dioctyl phthalate, polyethylene glycol and other raw materials and adding compatilizer, inhibitor, fire retardant, plasticizer and vulcanizing agent for reaction fusion, the preparation process method is simple, and the prepared product has high corrosion resistance, flame retardance and insulation performance and suitable for various fields.

Description

technical field [0001] The invention relates to the technical field of composite material production, in particular to a power heat insulation and flame retardant cable material and a preparation method thereof.
