The invention discloses an insulation epoxy resin material for an automotive relay shell. The insulation epoxy resin material is characterized in by comprising the following raw materials including, by weight, 100-130 parts of epoxy resin E40, 10-12 parts of methylhexahydrophthalic anhydride, 1-2 parts of magnesium stearate, 3-4 parts of triethyl acetyl citrate, 0.8-1 part of diphenyl imidazoline, 2-3 parts of alkenyl succinic anhydride, 1-2 parts of nickel aminosulfonate, 2-3 parts of acrylic polyoxyethylene glycol, 2-4 parts of microcrystalline wax, 0.6-1 part of trimethylbenzyl ammonium chloride, 10-12 parts of methyl acrylate, 0.04-0.1 part of ammonium persulfate, 0.01-0.02 part of divinyl benzene, 10-14 parts of nanosilicon dioxide and 0.1-0.3 part of coco fatty acid diethanol amide. According to the insulation epoxy resin material, the methyl acrylate serves as a monomer, the ammonium persulfate serves as an initiator, the diphenyl imidazoline is added into a mixture, and therefore obtained polymeric alcohol liquid has a certain antiseptic property; and the divinyl benzene serves as a cross-linking agent, nanosilicon dioxide dispersion liquid is added in the crosslinking process for modification, and therefore obtained nano-modification filler has very good intensity and toughness, and further has good compatibility with the epoxy resin.
