Abstract

The invention discloses a fireproof cable, and belongs to the technical field of cable material preparation. The fireproof cable is composed of a cable core and a protective sleeve which wraps the cable core. The protective cover comprises the following raw materials: ethylene propylene rubber, methylphenyl silicone resin, styrene butadiene rubber, fluorocarbon resin, ammonium polyphosphate, silica, carbon nanotubes, silicon-containing hydrogen, cellulose ether, carbon black N330, glass fiber, sodium silicate, chlorinated paraffin, dimethyl silicone oil, expanded vermiculite, modified heat-resistant agent, trisilyl phenyl silsesquioxane, an accelerant TMDT, zinc oxide, stearic acid, and an anti-aging agent RD. The fireproof cable is prepared by preparing a base material, preparing a modified material and then mixing the main material and the modified material. The cable material prepared by the invention has excellent fireproof performance.

Description

technical field [0001] The invention belongs to the technical field of cable material preparation, and in particular relates to a fireproof cable and a preparation method thereof. Background technique [0002] Among wire and cable insulation and sheath materials, polyvinyl chloride is relatively cheap, has excellent mechanical properties and is easy to process, making it the most widely used material in the wire and cable industry for a long time. Since the end of the 20th century, the environmental problems of polyvinyl chloride materials have been widely recognized, and some developed countries have put forward legal proposals to restrict or completely ban the use of polyvinyl chloride cables. In recent years, there has been a strong trend to control and ban the use of polyvinyl chloride materials. Then the cable insulation material of XLPE was developed. In order to ensure that polyethylene is used as an insulating material for cables, it is cross-linked to improve its ...
