Wear-resistant flame-retardant wire and cable material

Abstract

The invention discloses a wear-resistant and flame-retardant wire and cable material, which comprises a wear-resistant layer and a flame-resistant layer, the wear-resistant layer wraps the flame-resistant layer, and the wear-resistant layer is composed of the following weight ratio: polyvinyl chloride 35-60 parts, 40-55 parts of carbon nanotubes, 25-40 parts of talcum powder, 3-8 parts of stabilizer, 5-8 parts of lubricant, 2-6 parts of anti-wear agent, 2-6 parts of dimethyl silicone oil , 10-12 parts of naphthenic oil and 10-15 parts of composite filler, the flame retardant layer is composed of the following parts by weight: 8-15 parts of polyphenylene ether resin, 20-25 parts of polyolefin resin, 12-25 parts of silicone rubber 18 parts, 5-8 parts of silicon dioxide, 1-4 parts of flame retardant, 2-3 parts of antioxidant, 1-4 parts of crosslinking agent and 2-4 parts of coupling agent; the wear-resistant and flame-retardant wire The cable material can solve the current problems that the outer sheath of the wire and cable is easy to wear and the wire and cable are flammable.

Description

technical field [0001] The invention relates to a wear-resistant and flame-retardant wire and cable material. Background technique [0002] Flame-retardant cable refers to the cable that the sample is burned under the specified test conditions. After the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or residual flame can extinguish itself within a limited time. The fundamental characteristic is: it may be burnt out and cannot operate in case of fire, but it can prevent the spread of fire. In layman's terms, in the event of a wire fire, it can limit the combustion to a local area without spreading, keep other various equipment, and avoid greater losses. [0003] At present, the rubber power cords of outdoor power tools on the market, such as cutting machines, are often dragged back and forth on hard ground. With the continuation of use time, the rubber power cords will age at high temperature and weather, and the ...
