Halogen-free flame retardant polyolefin cable material of 125 DEG C with temperature resistance

Abstract

The invention provides a halogen-free flame retardant polyolefin cable material of 125 DEG C with temperature resistance. The cable material is prepared from the following raw materials, by weight, 40-50 parts of PE resin, 15-25 parts of ethane-octylene copolymer, 10-20 parts of ethane-tetrafluoroethene copolymer, 6-10 parts of compatilizers, 3-4 parts of polyvinyl alcohol superfine powder, 50-60 parts of magnesium hydroxide, 5-10 parts of tributyl citrate, 4-6 parts of glycerin, 10-12 parts of zinc borate, 5-8 parts of fluororubber, 1-3 parts of anti-oxidant 168, 1-2 parts of cross-linking agent TAC, 4-6 parts of aluminum phosphate, 1-2 parts of melamine cyanurate, 1-2 parts of allyl heptanoate and 8-10 parts of modified filling materials. The cable material has excellent flame retardance and incombustibility. Through addition of wear-resisting resins, surface wear-resisting agents and modified filling materials, the cable material keeps good mechanical properties, and therefore the wear resistance of the cable material is raised greatly.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a halogen-free flame-retardant polyolefin cable material with a temperature resistance of 125°C and a preparation method thereof. Background technique [0002] With the rapid development of the global economy and the enhancement of human awareness of environmental protection, the requirements for the quality and performance of wires and cables in various fields are getting higher and higher, and there are more and more fires caused by the aging of wires and cables. How to reduce the 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 halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or aluminum hydro...

Problems solved by technology

Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or aluminum hydroxide to polyolefin substrates to achieve flame retardancy. However, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing performance of the cable material. Its softness, poor weather resistance, oil resistance, and low temperature resistance at room temperature are not very good.
