Abstract

The invention relates to the technical field of insulated cable production, and particularly discloses a polyvinyl chloride cable composite material and a preparation method and application thereof, and the polyvinyl chloride cable composite material comprises the following raw materials: polyvinyl chloride resin, a plasticizer, nano calcium carbonate, a stabilizer, MBS resin, calcined kaolin, argil, a flame retardant and butyl stearate. Through reasonable use of various raw materials, compared with an insulation protection layer prepared from rubber, the wear resistance and the temperature resistance can be effectively improved, and the problem that an existing insulation cable cannot have good wear resistance and temperature resistance when rubber is adopted as an insulation material is solved. Moreover, the preparation method of the polyvinyl chloride cable composite material provided by the embodiment of the invention is simple, other types of insulating materials can be prepared for preparing insulated cables, and the polyvinyl chloride cable composite material has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of insulated cable production, in particular to a polyvinyl chloride cable composite material and its preparation method and application. Background technique [0002] With the continuous development of technology, people's demand for equipment and electronic products is also increasing. Among them, wire and cable and other products are common electric (magnetic) energy transmission materials, which can realize the conversion of information and electromagnetic energy, and are widely used in the communication industry. [0003] Among them, the cable in the narrow sense generally refers to an insulated cable, usually including a conductor and a coated insulating material. At present, rubber is mostly used as the insulating material in the production of insulated cables. However, although the insulated cables produced by using rubber as the insulating material can guarantee the insulation performance, they can...
