NOVELTY - Aging-resistant insulating coating material comprises 80-120 pts. wt. methyl phenyl silicone rubber, 10-30 pts. wt. low molecular weight butyl rubber, 5-15 pts. wt. hydroxyl silicone oil, 4-10 pts. wt. hollow glass microbeads, 10-20 pts. wt. aluminum hydroxide flame retardant, 5-15 pts. wt. fumed silica, 3-8 pts. wt. nano titanium dioxide, 1-5 pts. wt. graphene, 0.5-2 pts. wt. colorant, 2-6 pts. wt. coupling agent, 4-10 pts. wt. crosslinking agent and 2-4 pts. wt. catalyst. USE - As aging-resistant insulating coating material. ADVANTAGE - The aging-resistant insulating coating material has excellent high and low temperature resistance, weather resistance, aging resistance and durability. The method uses multi-functional crosslinking system, alkoxytitanium complex and organotin catalyst system, where the alkoxytitanium complex is added in an environment with organotin as a catalyst to promote catalytic efficiency and so that the cured product has excellent mechanical and electrical properties after curing and the storage stability of the product is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the aging-resistant insulating coating material, comprising (S1) mixing methyl phenyl silicone rubber, low molecular weight butyl rubber and hydroxyl silicone oil, and stirring, (S2) mixing coupling agent with the materials obtained in step (S1), adding nano titanium dioxide, graphene and aluminum hydroxide flame retardant, and stirring, (S3) mixing hollow glass microbeads, fumed silica, colorant and the materials obtained in step (S1), stirring and kneading, and removing residual moisture using a vacuum pump, continuously kneading the mixture uniformly to obtain paste sizing material, and (S4) cooling the paste sizing material prepared in step (S3) to 40-50℃, adding a crosslinking agent and a catalyst, and continuously kneading under the normal pressure state of filling nitrogen gas and uniformly dispersing the liquid component in the paste sizing material system to obtain the product.
