In this paper, the silicone modified polyether epoxy resin was prepared using silicone rubber, liquid epoxy resin and polyether by the method of blending modification. Then the sealant for the cable connection box was synthesized with this resin as matrix resin, and adding curing agent, flame retardant agent, aecelerant, mold discharging agent and enhancing fillers. This sealant neither released heat nor absorbed heat in the curing process, and had little shrinking while the cured product had good elasticity, electric insulation, high temperature resistance, aging resistance, salt water resistance and shock resistance and it was dustproof and easily maintained.
