Abstract

The invention belongs to the technical field of insulating materials, and particularly relates to an ultraviolet-resistant insulating material, a preparation method of the ultraviolet-resistant insulating material and application of the ultraviolet-resistant insulating material in a cable for electrical equipment. The ultraviolet-resistant insulating material is prepared from the following components in parts by mass: 100 parts of polyvinyl chloride resin, 5 to 10 parts of modified polybutadiene, 10 to 20 parts of plasticizer, 10 to 20 parts of filler, 3 to 6 parts of composite ultraviolet-resistant composition, 0.2 to 0.8 part of antioxidant and 1 to 3 parts of lubricant, the average polymerization degree of the polyvinyl chloride resin is 900-1100, the content of residual vinyl chloride monomers is smaller than or equal to 5 ppm, the number of impurity particles is smaller than or equal to 20 / 100 g, and the number of fisheyes is smaller than or equal to 20 / 400 cm < 2 >. The ultraviolet-resistant insulating material provided by the invention has excellent ultraviolet resistance.
