The invention relates to conductive rubber with silvering carbonyl nickel powder particles and a preparation method thereof and belongs to the field of preparation of conductive rubber. The problems of insufficient conductive performance and electromagnetic shielding performance in existing nickel base conductive rubber are solved. During preparation, a certain amount of carbonyl nickel powder isadded to alkali wash solution with a certain concentration and pickling solution with a certain concentration respectively to conduct silvering pretreatment and then added to silvering solution to obtain silvering carbonyl nickel powder with excellent conductive performance and electromagnetic shielding performance, then the obtained silvering carbonyl nickel powder is added to a silicone rubber matrix, liquid rubber is prepared by using a traditional preparation method, finally, the structural distribution of the silvering carbonyl nickel powder in the silicone rubber matrix is optimized through a magnetic field indu
