Abstract

Belonging to high polymer materials for electric wires and cables, the invention relates to a 150DEG C irradiation crosslinking low-smoke halogen-free flame retardant polyolefin material for locomotive wires and its preparation. The 150DEG C irradiation crosslinking low-smoke halogen-free flame retardant polyolefin material for locomotive wires provided in the invention comprises base resin, functionalized polyolefin resin, a halogen-free flame retardant, a surface modifier, a main antioxidant, auxiliary antioxidants, an anti-copper agent, a lubricating agent and a crosslinked sensitizer. The 150DEG C irradiation crosslinking low-smoke halogen-free flame retardant polyolefin material for locomotive wires has the advantages of high temperature resistance grade, good oil-proofness, relatively low cost, no halogen in the whole system, low smoke during combustion and the like, it also has excellent extrusion process performance. Cables extruded from the low-smoke halogen-free flame retardant polyolefin material can completely meet the requirements of 150DEG C cables for locomotive wires.

Description

technical field

[0001] The invention relates to a polymer material for wires and cables, in particular to a radiation cross-linked low-smoke, halogen-free, flame-retardant polyolefin material for 150°C locomotive wire and its preparation. Background technique

[0002] Locomotive lines are mainly used in relatively closed environments such as subway vehicles and rolling stock, where people are concentrated and have strict requirements for low-smoke and halogen-free performance. In addition to high-efficiency flame retardancy, it must also have good high and low temperature performance and oil resistance. In addition, in order to prevent wires and cables from producing a large amount of toxic hydrogen halide gas and smoke in case of accidental fire and prevent secondary disasters, wires and cables for locomotive lines should also have excellent low-smoke and halogen-free performance.

[0003] At present, the temperature resistance grade of the cable materials that can be used...
