Abstract
The invention discloses a molten steel sputtering prevention tensile movement round cable, and belongs to the technical field of wires and cables. The round cable capable of preventing molten steel from sputtering and stretching is sequentially provided with a conductor wire core, a mica tape, an insulating layer, a filler, a wrapping tape, a protective sleeve and a braiding layer from inside to outside. The cable disclosed by the invention has excellent flame retardant property and tensile property. The terminal carbon-carbon double bond of the auxiliary agent in the protective sleeve has chemical action with the matrix resin and the modified graphene under the action of the initiator, so that the auxiliary agent can be firmly existing in the cable, the dispersibility of the modified graphene is improved, and the auxiliary agent and the modified graphene act together to endow the cable with excellent flame retardance, tensile strength, wear resistance, weather resistance and other characteristics. Under long-time illumination, the binding force among the auxiliary agent of the protective sleeve, the modified graphene and the matrix resin can be further improved, so that the cable provided by the invention has excellent and stable comprehensive performance for a long time; the protective sleeve, the braiding layer and other structural combinations can effectively prevent the cable from being damaged by molten steel sputtering.
Description
Technical Field
The invention belongs to the technical field of wires and cables, and particularly relates to a round cable capable of preventing molten steel from sputtering, stretching and moving.
Background
With the progress of the age and the development of economic construction, the use of cables is becoming more and more widespread. In some special occasions, the cable has special and severe use environment, high tensile force and extremely high environment temperature, so that special and severe requirements are imposed on the cable, such as a large amount of molten steel and steel slag generated in the operation process of a converter, the molten steel and the steel slag can be inevitably splashed, thrown and bumped on the cable for traction, the phenomena of cable short circuit, even fire and the like can be caused, the common cable has low fireproof performance, particularly the fire resistance of the molten steel is poor, and the cable car is stretched, ground is worn, the cable is damaged to different degrees and even scrapped, if the cable is not solved radically, not only economic loss and resource waste are caused, but also serious accidents can be caused. Therefore, there is a need to design a round cable for preventing molten steel from sputtering and stretching.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a round cable capable of preventing molten steel from sputtering, stretching and moving.
The aim of the invention can be achieved by the following technical scheme:
the round cable for preventing molten steel from sputtering and stretching is sequentially provided with a conductor wire core, a mica tape, an insulating layer, a filler, a wrapping tape, a protective sleeve and a braiding layer from inside to outside;
further, the conductor wire core is formed by twisting a galvanized steel core in the middle and a copper bundle wire core at the periphery.
Further, the mica tape is a double-sided synthetic fire-resistant mica tape coated on the peripheral side surface of the conductor wire core.
Further, the insulating layer is one or more of a perfluoroethylene propylene insulating layer, a crosslinked polyethylene insulating layer and a butyl rubber insulating layer.
Further, the filling material is one or more of glass fiber, aramid fiber, cotton thread, hemp rope and polypropylene rope.
Further, the wrapping tape is non-woven fabric.
Further, the protective sleeve comprises the following raw materials in parts by weight:
