Problems solved by technology

The prices of these raw materials used in the production of the sheath tubes are relatively high, so the prices of the sheath tubes made of these materials are correspondingly high
[0003] At present, enterprises producing plastic-steel products produce a large amount of waste plastic-steel (left corners) after the finished products are made, and the disposal of waste plastic-steel is a very headache for enterprises; there are also waste plastic-steel products after people use them. Difficult to handle
Not only does it take a lot of manpower to dispose of these waste plastic steels, but the disposal of waste plastic steels as garbage not only causes environmental pollution, affects the ecological environment, but also causes a great waste of limited resources, and the resolution of these problems has not yet been reported.

Abstract

The invention discloses a cable sheathing of carbon thread production which use waste buried plastic steel. The thread of sheathing the main raw material is plastic steel scrap, in the production process, molten materials twin-screw extruder, Direct though stereotypes, do not use single-screw extruder melting process, so that the production process is simple. This invention is the dominant effect: resolving the waste plastic steel products of recycling, to environmental protection, but also to reduce the existing thread buried cable sheathing of the cost of production, greatly improving the products flame retardant, aging resistance , rigid flexible, and to increase the economic benefits of this enterprise.

Description

technical field [0001] The invention relates to a cable threaded sheathing pipe, in particular to a flame-retardant buried cable carbon threaded sheathing pipe produced by using waste plastic steel. Background technique [0002] Flame-retardant buried cable sheathing tube has been widely used in the power cable industry, and its production technology has also matured. However, the raw materials used in the production of sheath pipes generally adopt finished polyvinyl chloride, chlorinated polyvinyl chloride, polyethylene, polypropylene and other pellets as the main raw materials. For example, in the patent literature: the name is "electric cable plastic sheath tube" (publication number CN1139278A), and the main raw materials used in the disclosed technical solution are polyvinyl chloride and chlorinated polyvinyl chloride; High-voltage power cable sleeve and production method thereof" (publication number CN1508925A), the main raw material that the disclosed technical scheme...
