Technical Field
The invention relates to the technical field of production and manufacturing of wrapping tapes for cables, in particular to a PP wrapping tape for producing wires and cables and a manufacturing method thereof.
Background
With the rapid development of the economic society and frequent fire accidents of various cables, the cable fire has the characteristics of fast spread, difficult fire fighting, secondary hazard generation, long recovery time and the like, and brings great loss to national economy and lives and properties of people, so people pay more and more attention to the fire hazard of the electric wires and cables, and the requirements of related national departments on the performance indexes of fire prevention, flame retardance and the like of the electric wires and cables are higher and higher. A mica tape wrapping method is adopted in the cable, and the mica tape is sintered and hardened when the cable is burnt, so that the insulation effect can be continuously achieved, and the fire-resistant effect is achieved.
The wrapping tape is used as a production material commonly used in cable production, is widely applied to cables, most of the existing wrapping tapes are made of polypropylene, although the polypropylene has many advantages, the wrapping tape has strong electrical insulation and high volume resistivity, and due to the excellent electrical insulation, static charges can be accumulated in PP products in production and use, so that damages and accidents are caused. Therefore, it is necessary to eliminate static electricity of PP and to reduce resistivity. Therefore, the invention provides a PP lapping tape for wire and cable production and a manufacturing method thereof.
