Problems solved by technology

Polyvinyl chloride is a commonly used sheath material. Because the impact resistance of PVC is not very good, the impact resistance of existing cable sheath materials is not good. In addition, as an organic polymer material, it has flame retardancy and weather resistance. Sex is not very ideal, which limits its application in some special fields

Abstract

The invention discloses a weather-proof and flame-retardant PVC (polyvinyl chloride)-sheathed cable. Raw materials of a sheath comprise PVC, chlorinated polyethylene, styrene-butadiene block copolymers, hydroxyl-terminated polybutadiene, dodecafluoroheptyl methacrylate, beta-(3,5-diterbutyl-4-hydroxyphenyl) propionate octadecanol ester, modified montmorillonite, expansible graphite, zinc borate, nano ZnSn(OH)6, a heat stabilizer, butyl stearate, cerium stearate, ethylene glycol dimethacrylate, dioctyl adipate, hexaphenoxycyclotriphosphazene, modified carbon nano tubes, isobutyl triethoxysilane and 4,4'-thio-bis(6-t-butyl-3-methyl phenol). According to the weather-proof and flame-retardant PVC-sheathed cable, the shock resistance of the sheath is good, the flame retardance and weathering resistance are excellent, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a weather-resistant and flame-retardant polyvinyl chloride sheathed cable. Background technique [0002] With the development of society, cables have been used in various fields such as industrial and mining enterprises, energy and transportation departments, and protection lines. With the rapid development of the cable industry, the quantity and quality of cable materials are also increasing, and the overall technical level of the industry is greatly improving. Polyvinyl chloride is a commonly used sheath material. Because the impact resistance of PVC is not very good, the impact resistance of existing cable sheath materials is not good. In addition, as an organic polymer material, it has flame retardancy and weather resistance. The defect of non-ideal performance limits its application in some special fields. Contents of the invention [0003] Based on the technical problems ...
