Sheath material with scrape and friction resistance, low friction, low smoke and zero halogen, and flame retardation as well as preparation method thereof

Abstract

The invention discloses a sheath material with scrape and friction resistance, low friction, low smoke and zero halogen, and flame retardation. The sheath material comprises the following components in parts by weight: 10-15 parts of EVA, 2-5 parts of a silane coupling agent, 70-90 parts of a flame retardant, 5-8 parts of a lubricant, 5-8 parts of a compatilizer, 2-5 parts of a smoke suppressant, 2-5 parts of a viscosifier, 8-10 parts of a flow promoter, 1-5 parts of an anti-oxidant, and 5-8 parts of a flexibilizer. EVA is used as a carrier, the silicone coupling agent is used as a main component, aluminium powder is used as a fire retardant, blending and granulation are carried out in order to produce a high-molecular material silicone master batch, high density polyethylene is used as a compatilizer, so that an ethylene and acetic acid copolymer and the inorganic fire retardant aluminium powder are fully mixed and tightly combined; silicon system and molybdenum system compounds are added into the material formula system as lubricants in order to reduce the friction coefficient of the material surface; halogen is not contained in the material, so that halogen free performance of cables is guaranteed, and environmental protection benefits are provided. The sheath material has the advantages of flame retardation, low friction, scrap and friction resistance, and the like; and the sheath material can be applied to outdoor wiring systems, in order to improve wiring quantity and wiring length.

Description

technical field [0001] The invention relates to a cable sheathing material and a preparation method thereof, in particular to a scratch-resistant, low-friction, low-smoke, halogen-free, flame-retardant sheathing material and a preparation method thereof. Background technique [0002] At present, with the introduction of EU ROHS and REACH environmental protection regulations and the needs of public safety, low-smoke, halogen-free and flame-retardant polyolefin materials have replaced PVC in the field of wire and cable and are widely used in power cables, data communication cables and optical cables. In the communication wiring system, some cables are routed through pipes. For example, one installation method of FTTH is pipe wiring. Due to the limited space in the pipe, the number of line elbows and the number of wiring are large, which brings a lot of trouble to the pipe and takes a long time. , high cost and inconvenient construction. This requires not only low-smoke and ha...
