Quickly-vitrified fire resisting cable material

Abstract

The invention provides a quickly-vitrified fire resisting cable material. The fire resisting cable material is prepared from the following raw materials in parts by weight: 40-50 parts of ethylene-vinyl acetate copolymer, 30-40 parts of polyethylene, 20-35 parts of natural rubber, 30-40 parts of butadiene styrene rubber, 4-6 parts of a compatilizer, 1-2 parts of zinc oxide, 20-30 parts of argil, 10-15 parts of kaolin, 5-6 parts of medical stone, 6-7 parts of garnet, 1-2 parts of 3-aminopropyl trimethoxy silane, 3-4 parts of rapeseed oil, 1-2 parts of pentaerythritol, 1-2 parts of melamine cyanurate, 1-2 parts of molybdenum trioxide, 4-6 parts of ammonium molybdate, 1-2 parts of copper oxide, 1-2 parts of polytetrafluoroethylene micropowder, 10-12 parts of DIBP (diisobutyl phthalate), 6-8 parts of tributyl acetocitrate, 2-4 parts of epoxyoctyl stearate, 1-2 parts of a crosslinking agent TAIC (triallyl isocyanurate), 1-2 parts of ferrocene, and 12-15 parts of a modified filler. The fire resisting cable material is high in fire resistance. At high temperature, the fire resisting cable material can be quickly vitrified to protect the normal use of a cable. Meanhwile, the fire resisting cable material is environment-friendly and high in weather resistance.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a rapid ceramicization refractory cable material. Background technique [0002] Wire and cable are indispensable and important materials in industrial and agricultural production and modern life. my country is the world's largest producer of wire and cable. The wire and cable industry occupies a very important position in my country's national economy. However, at present, the market The cable material is not resistant to high temperature and aging, and the material turns yellow and becomes brittle after the aging test. There are more and more fires caused by aging wires. How to reduce the incidence of fire and the death rate in the event of fire, low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for non-halogen low-smoke rapid ceramic refractory cable materials is...

Problems solved by technology

Among them, the demand for non-halogen low-smoke rapid ceramic refractory cable materials is increasing. At present, most of the production of halogen-free low-smoke rapid ceramic refractory cable materials is to add a large amount of acetylene carbon black or acetylene carbon black to polyolefin substrates. However, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing of cable materials.
