The invention relates to the technical field of medical materials, in particular to medical grade silicone rubber capable of contacting a wound surface. The preparation method comprises the following steps: crushing moso bamboos, ingeniously performing segmented fermentation by using specific bacillus subtilis and bacillus coagulans, preparing graphene quantum dot coated nano-silver zinc from the crushed moso bamboos and a prepared silver-zinc nano-composite antibacterial agent, performing room-temperature pressing plate vulcanization to obtain silicon rubber with good antibacterial property, and finally adding a hydrophilic solution to obtain the silicon rubber with good antibacterial property. And taking out the solid after soaking, and air-drying to obtain the hydrophilic and antibacterial silicone rubber. The medical grade silicone rubber prepared by the invention can be used for various burn wounds, donor area wounds, soft tissue defects with exposed hand tendons, open crush wound wounds and the like.
