摘要

PURPOSE: Provided are a silicone sponge which is excellent in ventilation and elasticity and has flame retardancy, a deodorizing effect, an antibacterial effect and a far infrared emitting effect, its preparation method, and a functional article prepared by using the sponge such as a sheet or cushion for a vessel, a vehicle and a train, a sole, a cushion, a mattress, a brassiere, etc. CONSTITUTION: The silicone sponge comprises a polyurethane sponge; and a silicone solution containing at least one selected from the group consisting of an antibacterial agent, a flame retardant, a photocatalyst and a natural material which is infiltrated into the sponge. The method comprises the steps of mixing siloxane and an organic solvent to prepare a silicone solution; controlling the viscosity of the silicone solution; soaking a polyurethane sponge into the silicone solution; pressurizing the polyurethane sponge; and drying the obtained polyurethane sponge with hot wind.
