Problems solved by technology

[0004] In the field of rail transit, the basic materials of cable insulation materials used in existing vehicles are basically polyethylene or polypropylene. Such materials have poor softness at room temperature, and oil resistance needs to be improved.
The poor flexibility will bring a lot of inconvenience to the user during the laying process; the poor oil resistance will cause the cable to age quickly in the oil, and its electrical performance will hardly meet the national standard after aging.
[0005] Soft and oil-resistant cables have not been well resolved due to certain problems in formula design and material selection.

Abstract

The invention provides a low-smoke halogen-free flame retardant oil-resistance super-soft elastomer cable material which comprises the following components in parts by weight: 100 parts of basic resin, 20-50 parts of fire retardant A, 15-25 parts of fire retardant B, 0.8-2 parts of antioxidant, 0.4-2 parts of lubricant, 0.8-3 parts of coupling agent and 10-30 parts of plasticizer, wherein the basic resin is a thermoplastic polyurethane elastomer (TPU); the plasticizer is dimethoxyethyl phthalate (DMEP); the fire retardant A is a compounded phosphorus-nitrogen fire retardant; the fire retardant B is a compound of zinc oxide, molybdenum trioxide and carbon black according to the weight ratio of the components of (5-8):(1-2):(9-15). The prepared cable material has the characteristics of low-smoke, no halogen, flame retardant, oil-resistance and super softness.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant cable material and a preparation method thereof, in particular to a low-smoke, halogen-free, flame-retardant, oil-resistant, extra-soft elastic cable material and a preparation method thereof. Background technique [0002] With the rapid growth of wire and cable applications and rapid economic development, the quality and performance requirements of wire and cable materials are increasing in various fields, especially the requirements for softness, weather resistance and oil resistance of cable materials. [0003] At present, oil-resistant cables have been widely used in my country's petroleum, chemical, marine engineering and rail transit fields. However, with the general demand for oil-resistant cables, accidents caused by poor cable oil resistance are also on the rise every year. [0004] In the field of rail transportation, the basic materials of cable insulation materials used in existing veh...
