Abstract
The invention discloses an environment-friendly and non-toxic polyvinyl chloride cable material with high performance, heat resistance, oil resistance and low-temperature resistance as well as a preparation method thereof and a cable. The polyvinyl chloride cable material is prepared from the following formula components in parts by weight: 100 parts of polyvinyl chloride resin, 10-30 parts of filling agent, 20-25 parts of plasticizers, 10-18 parts of environment-friendly stabilizers, 6-15 parts of modifiers, 5-10 parts of insulation resisting agents, 4-10 parts of environment-friendly flame retardants and 1-3 parts of coloring agents. The preparation method of the polyvinyl chloride cable material comprises the following steps: obtaining polyvinyl chloride raw material components, mixing the weighed components, and fusing, extruding and plasticizing the mixed materials. The cable comprises the polyvinyl chloride cable material. The polyvinyl chloride cable composite material provided by the embodiment simultaneously has excellent high-temperature resistance and low-temperature resistance, high insulation performance, oil resistance and weather resistance, and is environmentally friendly and non-toxic; the polyvinyl chloride cable composite material prepared by the preparation method is stable in performance; the cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a polyvinyl chloride cable composite material, a preparation method thereof and a cable containing the polyvinyl chloride cable composite material. Background technique [0002] At present, from the published technical standards, the highest temperature resistance grade of PVC cable materials in the US UL758 / 1581 standard is 105°C, and the accelerated aging condition is 136°C / 168 hours accelerated constant temperature. In the Chinese GB8815 standard, the highest temperature resistance The temperature grade is 90°C, and the accelerated aging condition is 135°C / 240 hours. In the European VDE0218 standard, the highest temperature resistance level is 90°C, and the accelerated aging condition is 135°C / 336 hours. However, materials with a temperature resistance level of 125°C and above are basically cross-linked polyethylene materials, silicone rubber ma...
