Abstract

The invention relates to the field of cables, and particularly relates to a flame-retardant polyvinyl chloride insulation shielding control cable material which is prepared from the following components in parts by weight: 55 to 80 parts of modified polyvinyl chloride, 25 to 50 parts of chlorinated polyvinyl chloride, 10 to 20 parts of a flame retardant, 15 to 30 parts of an electromagnetic shielding material, 1 to 6 parts of a lubricating agent and 0.05 to 0.5 part of an antioxidant. The material solves the problem that the traditional insulating cable material or shielding cable material haslower flame retardancy, is easy to ignite in case of fire and is very unsafe and then a cable material with insulating and shielding functions and better flame retardancy is urgently needed. The flame-retardant polyvinyl chloride insulation shielding control cable material comprises modified polyvinyl chloride, chlorinated polyvinyl chloride, a flame retardant, an electromagnetic shielding material, a lubricant and an antioxidant, and through the cooperative use of the components, the finally obtained cable material has excellent insulation, shielding resistance and flame retardancy.

Description

technical field [0001] The invention relates to the field of cables, in particular to a flame-retardant polyvinyl chloride insulating and shielding control cable material. Background technique [0002] Cable is already an indispensable product in today's social life. Whether it is a power cable or a communication cable, it is inseparable from the work and life of ordinary people. However, with the continuous progress of society, the material requirements for cables are getting higher and higher. While durable, it must also have anti-shielding and insulating properties. [0003] Traditional insulated cable materials or shielded cable materials have low flame retardancy, and are easy to ignite in the event of a fire, which is very unsafe. Therefore, there is an urgent need for a cable material that not only has insulation and shielding functions, but also has better flame retardancy. Contents of the invention [0004] In view of the above problems, the present invention pro...
