The invention relates to a modified silicone rubber, a preparation method and applications thereof, and an antibacterial silicone rubber product, and belongs to the technical field of medical material. The raw materials of the modified silicone rubber comprise polydimethylsiloxane, vinyl terminated polysiloxane, octamethyltetrasiloxane, a catalyst, glycidyl ether epoxy resin, a surface modifier, carboxymethyl chitosan, and an aloe extracted product. The modified silicone rubber possesses excellent bacteria inhibition effect, is capable of solving a problem in the prior art that injection is caused because of bacteria propagation caused by the poor bacteria inhibition effect of conventional silicone rubber. The preparation method is simple and rapid, and is suitable for industrialized production. The above modified silicone rubber can be used for preparing the silicone rubber product with bacteria inhibition effect, and the silicone rubber product is provided with excellent bacteria inhibition effect.
