Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an environmentally friendly insulation control cable wire material and its preparation method, which solves the problem that the existing cable wire materials are easily burned due to external environmental factors during the power transmission process. At the same time, a large amount of irritating smoke will be released, so that in some relatively closed environments, it will not only affect the escape of personnel, but also seriously affect the environment.

Abstract

The invention discloses an environmentally friendly insulation control cable material and a preparation method thereof, including a first step of prefabricating inner sleeves, a second step of prefabricating outer sleeves, a third step of enhancing performance, a fourth step of reprocessing and a fifth step of extruding to form, which is: extruding a raw material D prepared in the fourth step andcladding the surface of cables after forming to obtain a pre-finished product A, and then extruding a raw material C prepared in the third step and cladding the surface of the pre-finished product A.The invention relates to the technical field of wires and cables. The environmentally friendly insulation control cable material and the preparation method thereof directly process the cable materialto divide into inner and outer layers and improve the extension coating performance of the inner layer to protect the wires in seal, thereby reducing the burning probability of the cables. Meanwhile an environmental protection material is adopted to make the inner layer, which effectively reduces pollutants produced by cable combustion, and a flame retardant material is added to outer sleeve materials, which effectively reduces the probability of combustion due to environmental guidance.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to an environment-friendly insulation control cable wire material and a preparation method thereof. Background technique [0002] Environmental protection means that human beings consciously protect natural resources and enable them to be rationally used to prevent the natural environment from being polluted and damaged; to comprehensively manage the polluted and damaged environment to create an environment suitable for human life and work, The concept of coordinating the relationship between man and nature, allowing people to live in harmony with nature. [0003] Wire and cable are wire products that transmit electrical energy, electrical signals and realize electromagnetic energy conversion. Cables are usually composed of a cable core that transmits electrical power or electrical signals and a sheath that plays a protective and insulating role. It only contains o...
