Abstract
The invention discloses a method for manufacturing silicone rubber. The method comprises the following steps: step 1, mixing a silicone rubber matrix, a cross-linking agent and an electric conductivemedium and a magnetic conductive medium on a double-roll open mill for 1-2h at a temperature of 100-130 DEG C; and step 2, placing the mixed composite material in a flat vulcanizing machine for compression molding at a temperature of 90-170 DEG C under 6-18MPa, wherein the electric conductive medium is silver-plated copper powder, the magnetic medium is silver-plated nickel powder, and a mass ratio of the silicone rubber matrix to the cross-linking agent to the electric conductive medium to the magnetic conductive medium is 4:(1-10):(100-400):(80-200). The invention solves a problem of poor electromagnetic shielding capacity of a silicone rubber manufactured in the prior art.
