Abstract

The invention discloses a polyvinyl chloride cable composite material, a preparation method thereof and a cable. The polyvinyl chloride cable composite material of the present invention comprises the following components in parts by weight: 100 parts of polyvinyl chloride resin, 5-30 parts of filler, 30-60 parts of plasticizer, 5-15 parts of stabilizer, pre-crosslinked modification 10-25 parts of stabilizer, 5-10 parts of flame retardant, 1-3 parts of colorant, 5-10 parts of crosslinking agent. The inventive cable comprises the inventive polyvinyl chloride cable material. The polyvinyl chloride cable composite material in the embodiment of the present invention has excellent high temperature resistance, low temperature resistance, oil resistance, environmental protection and non-toxicity. The polyvinyl chloride cable composite material produced by the preparation method has stable performance and reduces cost.

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...
