The invention relates to the technical field of electric power facility materials and especially relates to an insulation isolation baffle plate. The insulation isolation baffle plate orderly comprises an insulation base layer, an anti-static layer and an adsorption layer from inside to outside. The insulation base layer comprises epoxy resin filled with a filler. The anti-static layer comprises an insulation base layer material and a silane coupling agent. The adsorption layer material is a hyperbranched polymer. The insulation base layer has thickness of 5mm. The anti-static layer has thickness of 1mm. The adsorption layer has thickness of 0.1-0.3mm. Through use of the anti-static layer and the adsorption layer, the insulation isolation baffle plate has excellent anti-static performances, does not influence insulativity, improves use safety, is prepared through simple processes, has excellent performances and has a good market prospect.
