▎ 摘　　要

NOVELTY - A shielding material comprises 30-60 pts. wt. chlorinated polyether, 10-20 pts. wt. polyether resin, 20-35 pts. wt. methylene acetoacetate, 5-15 pts. wt. polyamide, 5-10 pts. wt. polyimidazole, 5-10 pts. wt. methylpyridine, 0.5-1.5 pts. wt. graphene and 1-5 pts. wt. cross-linking agent. USE - Shielding material. ADVANTAGE - The shielding material has excellent shielding effect on electric field and high mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of shielding material, which involves (1) dissolving methyl acetoacetate in glycerol to form solution, adding nano calcium titanate, dispersing evenly and crystallizing to obtain methyl acetoacetate crystalline material, (2) adding methyl acetoacetate crystalline material, polyether resin, chlorinated polyether, methylpyridine, polyimidazole and polyamide and carrying out cross-linking reaction to obtain final product.
