High and low temperature resistant and aging resistant cloth electric wire and preparation method thereof

Abstract

This invention discloses a high- and low-temperature resistant and anti-aging building wire and its preparation method, relating to the field of wire and cable technology. The high- and low-temperature resistant and anti-aging building wire of this invention comprises: a wire core; and a modified polyvinyl chloride (PVC) insulation layer covering the wire core; wherein the modified PVC insulation layer comprises at least the following raw materials in parts by weight: 80-100 parts of PVC; 10-20 parts of hydrogenated nitrile rubber; 5-15 parts of PVC-g-polyacrylic acid graft copolymer; 10-25 parts of vinyltriethoxysilane coupling agent modified boron nitride / magnesium hydroxide composite flame retardant; 3-8 parts of linoleic acid modified polyhedral oligomeric silsesquioxane; 4-8 parts of heat stabilizer; 3-6 parts of plasticizer; 1.5-3.5 parts of lubricant; 0.5-2 parts of antioxidant; and 0.3-1.5 parts of ultraviolet absorber. The building wire prepared by this invention has wide temperature range adaptability, aging resistance, and flame-retardant and smoke-suppressing properties.
