Abstract

The invention discloses a high-temperature-resistant environmentally-friendly easy-to-tear PVC protective jacket cable material and a preparation method thereof. The PVC protective jacket cable material is prepared from the following components in parts by weight: 100 parts of polyvinyl chloride resin, 30 to 70 parts of trioctyl tribenzoate, 10 to 20 parts of epoxidized soybean oil, 70 to 120 parts of filler, 3 to 8 parts of environmentally-friendly stabilizer, 0.5 to 2 parts of antioxidant, 1 to 3 parts of lubricant and 0 to 2 parts of coloring agent, wherein the filler consists of 40 to 80 parts of calcium carbonate, 30 to 60 parts of talcum powder and 0 to 25 parts of argil. The PVC protective jacket cable material meets the requirement of a table 6 in Australian AS / NZS3808:2000 standard, meets various requirements in European Unit ROHS instruction, and is low in cost and high in stripping property.

Description

technical field [0001] The invention relates to a PVC sheathed cable material, in particular to a high-temperature-resistant, environment-friendly and easy-to-tear PVC sheathed cable material and a preparation method thereof. Background technique [0002] Among the soft polyvinyl chloride plastics used for wire and cable, the higher temperature resistance grade specified in GB / T8815-2002 is 90 ℃ polyvinyl chloride insulating material and sheathing material. [0003] When the cable is recycled, it is necessary to separate the wire core from the sheath layer. Therefore, the sheath material needs to be easy to peel (that is, easy to tear) when it meets the above standards. The invention patent with the publication number CN103665627A discloses an easy-to-peel PVC cable sheath material, which is mainly prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 3-8 parts of impact modifier, and 45-4 parts of plasticizer. 50 parts, 0.1-0.5 parts of anti...
