Abstract

The invention relates to a high-temperature resistant thermoplastic polyvinyl chloride cable material, belonging to the technical field of new materials. The cable material consists of the following components in parts by weight: 100 parts of polyvinyl chloride, 30-50 parts of modified plasticizer, 10-20 parts of plasticizer, 20-40 parts of modifier, 2-10 parts of flame retardant, 10-30 parts of inorganic filler, 5-15 parts of stabilizer and 1-5 parts of processing aid. A preparation method of the cable material comprises the following steps: weighing the raw materials according to the components and weight parts of the cable material; uniformly mixing the polyvinyl chloride and adding the modified plasticizer and the common plasticizer; heating and stirring and adding other raw materials; discharging from a high mixing machine and feeding into a twin-screw extruder for extrusion and granulation; and performing air cooling to obtain the final product. The cable material has the advantages that the physical property is good, the applicable temperature range is wide, little pollution is caused, the flame retardance is good, the smoke output in combustion is low, the preparation method is simple, and the cost is low.

Description

technical field

[0001] The invention relates to a cable material and a preparation method thereof, in particular to a high-temperature-resistant thermoplastic polyvinyl chloride cable material and a preparation method thereof, belonging to the technical field of new materials. Background technique

[0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields. While the consumption of wires and cables is increasing, the accidents of electrical fires are also increasing. The safety, environmental protection and service life of wire and cable products have higher requirements. The flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. . As early as the 1970s, flame-retardant cables were developed successively at home and abroad. Although these flame-retardant cables have certain flame-retardant effects, they still have many defects, such as poor high-temperature ...
