Abstract

The invention discloses a polyvinyl chloride resin cable sheath material and a preparation method thereof. The polyvinyl chloride resin cable sheath material comprises the following raw materials: polyvinyl chloride resin, polyurethane rubber, white carbon black, modified vermiculite powder, triphenyl phosphate, an accelerant TMTM (Tetramethyl Thiuram Monosulfide), an anti-aging agent RD, anilino-methyl-triethoxysilane, magnesium stearate, benzotriazole, zinc oxide and methyl methacrylate. By utilizing the polyvinyl chloride resin as a main material, the cable sheath is excellent in tensile strength and elongation at break, and also excellent in break-extending retention rate and impact brittle temperature after being aged. By modifying the vermiculite powder as a filling material, the inner connection of the cable sheath is enhanced, so that the cable sheath is effectively prevented from being broken. Therefore, the service life of the cable sheath is prolonged.

Description

Technical field [0001] The invention relates to a polyvinyl chloride resin cable sheath material and a preparation method thereof, and belongs to the field of cable sheath material manufacturing. Background technique [0002] With the rapid economic development, wires and cables have been widely used in various industries and fields. The frequent occurrence of electrical fire accidents and the flame-retardant problem of wires and cables have gradually attracted the attention of countries all over the world. When the cables are burned, they release a large amount of smoke and poison. Corrosive and corrosive gases are dangerous factors in fires. They hinder people’s safe evacuation and extinguishing work during fires, causing serious loss of life and property. At the same time, with the development of communication, automobile industry and computer industry, cable protection The quality requirements of jacket materials are increasing. The present invention provides a polyvinyl ...
