Problems solved by technology

However, the above-mentioned luminous substance is filled in the gap between the insulating sheath and the transparent insulating sheath, and no matter it is the luminous powder or the luminous tape, it is in a state of separation from the transparent insulating sheath; Bending causes the luminous material to be partially squeezed, which can easily lead to problems such as agglomeration of the luminous material and uneven dispersion, thus affecting the luminous effect and stability of the grounding wire

Abstract

The invention relates to the technical field of grounding wires, in particular to a noctilucent grounding wire and a processing technice. The noctilucent grounding wire comprises a grounding wire body, the grounding wire body comprises a copper core and an insulating sheath wrapping the copper core, and the insulating sheath is wrapped with a fluorescent sheath; the fluorescent sheath is preparedfrom the following raw material in parts by weight: 80-110 parts of polyvinyl chloride resin, 3-8 parts of an ethylene-vinyl acetate copolymer, 10-20 parts of a fluorescent material, 5-13 parts of a flexibilizer, 0.5-2 parts of an antioxidant and 1-3 parts of a coupling agent, the weight percentage of vinyl acetate in the ethylene-vinyl acetate copolymer is 30-35%; a fluorescent substance is addedinto the insulating sheath as a raw material, and the fluorescent substance can be uniformly dispersed in the insulating sheath, so that the grounding wire can emit light stably, and the problem thatthe grounding wire is omitted to be dismounted due to insufficient light is avoided; the tensile strength of the processed fluorescent sheath is up to 38 MPa, the elongation at break of the processedfluorescent sheath is up to 187%, the tensile strength and elongation at break of the processed fluorescent sheath are basically kept unchanged after aging, and the aging resistance of the processedfluorescent sheath is excellent.

Description

technical field [0001] The invention relates to the technical field of grounding wires, in particular to a luminous grounding wire and its processing technology. Background technique [0002] The grounding line is the line directly connected to the earth, and it can also be called a safety return line. When it is in danger, it directly transfers the high voltage to the earth, which is regarded as a lifeline. [0003] Due to poor insulation performance or humid use environment of household electrical equipment, the shell will have a certain amount of static electricity, and electric shock accidents will occur in severe cases. In order to avoid accidents, you can connect a wire to the metal shell of the electrical appliance, and connect the other end of the wire to the ground. Once the electrical leakage occurs, the grounding wire will bring static electricity into the ground and release it. [0004] In order to ensure the reliability of electricity used by users in normal li...
