Problems solved by technology

Traditional polyvinyl chloride cable material, the formula is: 100 parts of polyvinyl chloride, 50-60 parts of dioctyl phthalate, 6-10 parts of compound stabilizer, 1-3 parts of lubricant, 20 parts of active light calcium carbonate -30 parts, the above-mentioned materials are prohibited due to the use of dioctyl phthalate DOP as the plasticizer and the basic lead salt used as the stabilizer. Dioctyl phthalate will produce secondary pollution after burning
[0003] In order to solve the above-mentioned technical problems, a new type of environmentally friendly polyvinyl chloride cable material has recently been disclosed in Chinese patent documents, the application number of which is "200810023864. , the polyvinyl chloride cable material is prepared from the following raw materials, and its formula is: 85-105 parts of polyvinyl chloride, 50-60 parts of plasticizer DINP, 6-7 parts of Ca-Zn composite stabilizer, lubricant (stearic acid or polyethylene wax) 1-2 parts, active light calcium carbonate 20-30 parts, although the cable material produced by this formula has certain environmental protection, the cable material produced by this formula has the performance of anti-aging and high temperature / low temperature resistance Poor, mechanical properties 100° heat aging 168h (tensile strength, elongation at break, etc.) changes within ± 20%

Abstract

The invention provides a novel environment-friendly polyvinyl chloride cable material. The material consists of polyvinyl chloride WS-1300, plasticizer UN399, stabilizer CZ-756E (105), epoxidized soybean oil, bisphenol A antioxygen, antimonous oxide (SB203), polyethylene (PE), activated light calcium carbonate and carbon black. The chemical substance content of the material is reduced by improving the formula of the cable material, so that the product has the advantages of effectively solving the problem of toxic gases releasing in polyvinyl chloride material heating and plastifying process, reducing the harm to the human bodies in the production process, resisting the temperature of between 40 and 105 DEG C, along with cleanness and environmental protection, light specific gravity, high plasticization degree, no deformation, fracture or aging, superior product performance, and wider application range and field.

Description

technical field [0001] The invention relates to a polymer cable material. Background technique [0002] Wire and cable refers to materials used for power, communication and related transmission purposes. With the development of society, wires and cables are more and more widely used in various fields, such as transportation, communication, construction, etc. Therefore, the demand for wires and cables is also getting higher and higher. Traditional polyvinyl chloride cable material, the formula is: 100 parts of polyvinyl chloride, 50-60 parts of dioctyl phthalate, 6-10 parts of compound stabilizer, 1-3 parts of lubricant, 20 parts of active light calcium carbonate -30 parts, the above-mentioned materials are prohibited due to the use of dioctyl phthalate DOP as the plasticizer and the basic lead salt used as the stabilizer. Dioctyl phthalate will produce secondary pollution after burning. [0003] In order to solve the above-mentioned technical problems, a new type of enviro...
