NOVELTY - Aging-resistant wire insulation layer material comprises 40-45 pts. wt. ethylene-vinyl acetate copolymer, 10-15 pts. wt. butadiene rubber, 8-12 pts. wt. epoxy resin, 5-8 pts. wt. dibutyl phthalate, 5-8 pts. wt. micro silicon powder, 3-5 pts. wt. graphene compound, 1-3 pts. wt. calcium stearate, and 1.5-2.5 pts. wt. magnesium hydroxide. USE - Aging-resistant wire insulation layer material. ADVANTAGE - The aging-resistant wire insulation layer material is stable in structure, has good anti-aging and abrasion resistance, improves thermal stability, environmental protection and safety, and solves the problems of premature aging of traditional traditional insulating layers and the easy generation of chlorine-containing compounds. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing aging-resistant wire insulation layer material, which involves: (A) adding graphene oxide dispersion to the borax solution after 15 minutes of sonication, adding calcium nitrate solution, continue microwave reaction for 20-30 minutes, cooling to room temperature, filtering the filter cake, washing the filter cake with ethanol, dispersing the filter cake in ethanol, adding oleic acid, reacting under reflux for 15-20 minutes, cooling to room temperature, taking the filter cake by centrifugation, and drying to prepare the graphene composite, mixing product with micro silicon powder and magnesium hydroxide to prepare component one uniformly, and mixing calcium stearate with dibutyl phthalate to uniformly prepare component two; and (B) adding ethylene-vinyl acetate copolymer, cis-butadiene rubber and epoxy resin to the open mill, heat up to 50 degrees C, adding component two, after mixing for 1 hours, heating up to 80 degrees C, then adding the component one after mixing for 1.5 hours to obtain material immediately.
