Abstract

The invention discloses a polyolefin cable material and a preparation method thereof. The polyolefin cable material is prepared from, by weight, 20-40 parts of ethylene-vinyl acetate copolymer resin, 10-30 parts of polyolefin elastomers, 20-50 parts of ultralow-density polyethylene, 0-15 parts of functional polyolefin resin, 0-180 parts of a flame retardant, 0.5-1.5 parts of a crosslinking sensitizer, 0.5-2 parts of an auxiliary crosslinking agent, 0.1-0.5 part of a chain extender, 0.5-2 parts of an antioxidant and 3-9 parts of a processing aid. The polyolefin cable material is wide in application range, the flame-retardant polyolefin cable material or the non-flame-retardant polyolefin cable material can be prepared, and extrusion moulding is easy; in addition, the polyolefin cable material has the high crosslinking sensitization activity, volatilization is not prone to occur and no smoke is generated during extrusion, health of production personnel can be protected, and the operation environment is improved.

Description

technical field [0001] The invention belongs to the field of material chemistry and relates to a plastic particle, in particular to a polyolefin cable material and a preparation method thereof. Background technique [0002] Irradiation cross-linked polyolefin cable material is a commonly used cross-linked material for wires and cables. It has good safety, high temperature resistance, acid and alkali resistance, wear resistance, and no cracking. It is widely used in various types of cables. Radiation cross-linked polyolefin cable materials need to be irradiated after being extruded into wires and cables. Therefore, sensitizers to speed up the cross-linking speed and promote cross-linking uniformity will be added during the processing. The general sensitizers are due to the The main material has poor compatibility and low volatilization temperature. When extruding wires and cables, after high-temperature plasticization by the extruder, more irritating fumes are likely to be vo...
