Antistatic anti-explosion multifunctional special rope

Abstract

The invention discloses an antistatic anti-explosion multifunctional special rope which comprises a rope body. The rope body comprises an outer sleeve and a rope core arranged in the outer sleeve, therope core is prepared from polypropylene filament yarns, the outer surface of the rope core is prepared from high-strength polyester multifilaments doped with novel conductive fibers, and the outer sleeve is braided by a double-layer rope braiding machine. Preparation of the outer sleeve includes the steps: (1) twisting: twisting conductive fiber filament yarns and the high-strength polyester multifilaments into rope yarns by a twister; (2) stranding: pre-weaving the twisted rope yarns by a stranding machine into a rope strand conforming to the size of a spindle of the double-layer rope braiding machine; (3) braiding: braiding the rope strand around the rope core once by the double-layer rope braiding machine; (4) coating finish: dipping the rope body in a functional flame-retardant high-temperature-resistant coating, performing coating finish and then drying the rope body in a drying box. By the aid of the antistatic anti-explosion multifunctional special rope, the flame resistance and the high-temperature resistance of ropes are improved, and antistatic and anti-explosion properties of the antistatic anti-explosion multifunctional special rope are ensured.

Description

technical field [0001] The invention relates to the technical field of ropes, in particular to an antistatic explosion-proof multifunctional special rope. Background technique [0002] When ordinary chemical fiber ropes are used in flammable and explosive areas, such as coal mines and petroleum industries, which are more sensitive to static electricity, static electricity will be generated due to friction, which will induce static discharge, resulting in static fire and explosion safety accidents. Therefore, chemical fiber ropes used in areas that are particularly sensitive to static electricity have special requirements. In addition to flame retardant and high temperature resistance, they also require sufficient antistatic and explosion-proof performance. Therefore, urgently need those skilled in the art to develop a kind of antistatic explosion-proof multifunctional special rope. Contents of the invention [0003] The object of the present invention is to provide a spec...
