Abstract

The invention discloses a rapid-vulcanized low-smoke halogen-free flame retardant rubber cable material. The rapid-vulcanized low-smoke halogen-free flame retardant rubber cable material mainly comprises the following raw materials in parts by weight: 20-80 parts of natural rubber, 20-80 parts of butadiene-styrene rubber, 130-150 parts of flame retardant smoke suppression agent, 4-10 parts of flame retardant smoke suppression synergist, 1-3 parts of coupling agent, 1-3 parts of zinc dimethyldithiocarbamate, 1-5 of vulcanizing agent, 6-8 parts of zinc oxide, 1-3 parts of stearic acid and 1-2 parts of antioxidant. The rapid-vulcanized low-smoke halogen-free flame retardant rubber cable material has the beneficial effects that the cable material is easy to machine, an extruded wrapping technology is good, and products have good mechanical property and good low-temperature flexibility.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a rapidly vulcanized low-smoke halogen-free flame-retardant rubber cable material and a preparation method thereof. Background technique [0002] In order to reduce fire accidents caused by cable heating and burning, the use of flame-retardant cables is becoming more and more common; traditional halogen-containing flame-retardant cables will produce a lot of smoke and toxic, irritating and corrosive hydrogen halides in the event of a fire. Gas; smog can cause death and hinder firefighting and evacuation, hydrogen halide gas can corrode equipment and endanger human health. Therefore, it is mandatory to use halogen-free flame-retardant cables in places where many people gather, and the production of halogen-free flame-retardant cable materials is the key. [0003] For thermoplastic polyolefin low-smoke, halogen-free, flame-retardant cable materials, a large amou...
