Preparation method of novel fluorescent PVC wire/cable shield material

Abstract

The invention provides a preparation method of a novel fluorescent PVC wire / cable shield material. The preparation method comprises the following steps: (1) heating and stirring a terbium chloride solution and a phenanthroline solution together, adding a p-toluic acid solution, further stirring, standing, filtering, washing, and drying to obtain white powder; dissolving the white powder in dimethyl fumarate, adding distilled water to form a suspension, then adding sodium chloride and stearic acid, stirring, taking out, filtering and drying to obtain fluorescent powder; (2) adding ACR to the fluorescent power, stirring and mixing, extruding, melt spinning to obtain fluorescent fibers; (3) adding PVC, nano-montmorillonite, a heat stabilizer, a plasticizer, calcium carbonate, a coupling agent and an antioxidant together into a high speed stirrer for stirring to obtain a mixed material; and (4) dissolving the mixed material into a solvent, adding the fluorescent fibers, uniformly stirring to obtain a prepreg, drying, transferring to a die, heating, pressurizing and insulating heat, and naturally cooling to room temperature to obtain the fluorescent PVC wire / cable shield material. The shield material prepared by the preparation method provided by the invention has a relatively good fluorescent performance.

Description

Technical field: [0001] The invention relates to a wire and cable sheathing material, in particular to a preparation method of a novel fluorescent PVC wire and cable sheathing material. Background technique: [0002] PVC is the English abbreviation of polyvinyl chloride (Polyvinyl chloride), which is the polymerization reaction of vinyl chloride monomer (VCM) in peroxide, azo compound and other initiators, or by free radical polymerization under the action of light and heat. The polymers formed by mechanism polymerization, vinyl chloride homopolymer and vinyl chloride copolymer are collectively called vinyl chloride resin, which is a non-crystalline material. In actual use, PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, anti-impact agents and other additives, which have good processing performance, low manufacturing cost, corrosion resistance, insulation and other good characteristics, and are widely used. Among them One ...
