The invention provides a dental silicone rubber impression composition, a dental silicone rubber impression material kit and a preparation method and application of the dental silicone rubber impression composition and the dental silicone rubber impression material kit, D50 of reinforcing filler in the impression composition is 5-22 microns, and the particle size distribution of the reinforcing filler in the impression composition meets the conditions that D60-D40 is smaller than or equal to 12 m and D40-D20 is smaller than or equal to 12 m at the same time. The particle size distribution of the reinforcing filler in the impression material is controlled to be concentrated enough, so that the initial setting time of the silicone rubber impression material is controllable, and meanwhile, the silicone rubber impression material with relatively high overall strength is also obtained.
