Abstract

The invention discloses a fiber-reinforced composite coaxial cable material and a preparation method thereof. The preparation method comprises the following steps: (1) taking polystyrene, ethylene propylene diene monomer rubber, a melamine modified urea formaldehyde resin, hydroxypropyl methylcellulose, glass fibers, basalt fibers, hexametapol and allyl isothiocyanate according to parts by weight, adding the materials into a stirring tank, and stirring; (2) adding an antioxidant 1010, diamyl phthalate and propylene glycol monomethyl ether acetate into the stirring tank, and stirring while keeping the temperature constant; and (3) carrying out high-temperature extrusion on the mixed materials in the step (2) in a double screw extruder, and granulating, thereby obtaining the fiber-reinforced composite coaxial cable material. The fiber-reinforced composite coaxial cable disclosed by the invention has the characteristics of favorable properties and low cost.

Description

technical field [0001] The invention belongs to the field of cable materials, and relates to a fiber-reinforced composite coaxial cable material and a preparation method thereof. Background technique [0002] The coaxial cable is divided into four layers from the inside to the outside: the central copper wire (single-strand solid wire or multi-strand wire), plastic insulator, mesh conductive layer and wire sheath. The central copper wire and the mesh conductive layer form a current loop. [0003] The insulator materials used for coaxial cables have many components, including polyethylene, polyvinyl chloride, polyolefin and other components, which are used in the insulator materials of coaxial cables. Among them, some of the above-mentioned polymers have better thermoplasticity and flexibility of macromolecules, and have better flame retardancy and chemical corrosion resistance. However, due to the use of polar groups in some components, the electrical insulation performanc...
