Problems solved by technology

At present, the working environment of most cables is relatively harsh, mainly laying or hanging in tunnels and shafts, etc., and it is easy to cause cable fires due to their own failure or the influence of nearby fires.
Due to the limited enclosed space, the heat of combustion cannot be dissipated, and the fire will develop rapidly, resulting in thick smoke and harmful gases, which will not only cause failure of the power transmission system, but also pollute the environment, and more importantly, endanger people's personal safety

Abstract

The invention provides a fireproof high-flame-resistance cable material and a preparation method thereof. The fireproof high-flame-resistance cable material is prepared through the following steps of firstly, mixing and stirring zinc hydroxystannate, calcium-zinc stabilizer, antimonous oxide, nano-silicon dioxide, gallic acid propyl ester, beewax, oleamide and chlorinated paraffin; secondly, adding the mixture to a three-roller grinding machine to be ground, and continuing to stir the mixture for standby application; thirdly, mixing and stirring polyvinyl chloride, methylvinyl silicone rubber and fluorinated silicone rubber, and adding the mixture in the first step; fourthly, adding dioctyl phthalate and epoxy soybean oil, and raising the temperature; fifthly, adding magnesium hydrate, potassium sorbate and butylated hydroxytoluene, conducting stirring, and raising the temperature; sixthly, transferring the mixed material to a low-speed stirring machine to be stirred and cooled; seventhly, adding the mixed material to a double-screw extruder to be extruded and granulated. The fireproof high-flame-resistance cable material has a quite high oxygen index, belongs to a high-flame-resistance material, and has a high thermal deformation temperature; in addition, the fireproof high-flame-resistance cable material has a good mechanical property and is excellent in toughness.

Description

technical field [0001] The invention relates to the field of materials, in particular to a fireproof and highly flame-retardant cable material and a preparation method thereof. Background technique [0002] With the continuous development and progress of science and technology in our country, materials are also constantly updated. Among them, wires and cables are also developing rapidly with the development of electricity, and have become an indispensable part of every household and large and small enterprises. Cables are mainly divided into bare wires, winding wires, power cables, communication cables and communication optical cables, and wires and cables for electrical equipment. At present, the working environment of most cables is relatively harsh, mainly laying or hanging in tunnels and shafts, etc., and it is easy to cause cable fires due to their own failure or the influence of nearby fires. Due to the limited enclosed space, the heat of combustion cannot be dissipat...
