The invention relates to the technical field of silicone rubber, in particular to high-resilience silicone rubber and a preparation method thereof. The high-resilience silicone rubber comprises raw materials in parts by weight as follows: 90-100 parts of composite silicone rubber, 35-45 parts of a reinforcing agent, 1.5-2.5 parts of hydroxy-terminated polydimethylsiloxane, 0.15-0.25 parts of a silane coupling agent, 5-8 parts of magnesium oxide, 0.1-0.15 parts of a release agent, 0.6-1.0 part of a vulcanizing agent and 0.1-1.0 part of distilled water. By means of the materials such as the reinforcing agent, hydroxy-terminated polydimethylsiloxane, the silane coupling agent and the like, the prepared silicone rubber has high resilience rate and excellent resilience, further has the properties of better tensile strength, elongation at break, tear strength and the like, is high in mechanical strength and stability and has wide application range. 本发明涉及硅橡胶技术领域，具体涉及种高回弹硅橡胶及其制备方法，该高回弹硅橡胶包括如下重量份的原料：复合硅橡胶90-100份、增强剂35
