Abstract

The invention discloses an ultraviolet irradiation cross-linked cable material. The ultraviolet irradiation cross-linked cable material comprises, by weight, 20-50 parts of high-density polyethylene,80-100 parts of low-density polyethylene, 30-50 parts of flame retardants, 6-8 parts of melamine cyanurate, 2-4 parts of epoxidized soybean oil, 0.5-5 parts of ultraviolet absorbers, 0.2-0.5 part of coupling agents, 1-5 parts of antioxidants and 0.2-0.4 part of stearic acid. The ultraviolet irradiation cross-linked cable material has the advantages that the thermal properties and the temperature resistance of the ultraviolet irradiation cross-linked cable material can be improved, and accordingly the problems of low work environment temperatures and heat intolerance of existing ultraviolet irradiation cross-linked polyethylene insulation materials can be effectively solved by the aid of the ultraviolet irradiation cross-linked cable material.

Description

technical field [0001] The invention belongs to the technical field of cable materials, in particular to an ultraviolet light irradiation cross-linked cable material. Background technique [0002] With polyolefin as the main raw material mixed with an appropriate amount of enhanced cross-linking photoinitiation system, under certain conditions, it is irradiated with ultraviolet light, and the photoinitiator absorbs ultraviolet light of a specific wavelength to generate active macromolecular free radicals. A series of rapid cross-linking reactions with other additives, the individual polyethylene long-chain macromolecules are chemically bonded to form a three-dimensional network cross-linked polyethylene supramolecular structure. The cross-linked polyolefin material has excellent high temperature resistance, solvent resistance, excellent electrical properties and significantly enhanced mechanical properties, etc. Ultraviolet light irradiation crosslinking wire and cable is t...
