The invention relates to the technical field of silica gel, in particular to high-hardness and air-pressure-resistant silica gel and a preparation method thereof. The high-hardness and air-pressure-resistant silica gel comprises, by weight, 68-132 parts of silicone rubber, 60-70 parts of reinforcing agent, 13.6-15.4 parts of silane auxiliaries, 0.3-0.7 part of distilled water, 0.14-0.22 part of lubricating agent, 1-2 parts of hardness-increasing agent and 0.5-1.5 parts of vulcanizing agent. The high-hardness and air-pressure-resistant silica gel is high in hardness, good in air pressure resistance and excellent in comprehensive performance. 本发明涉及硅胶技术领域，具体涉及种高硬度耐气压硅胶及其制备方法，所述高硬度耐气压硅胶包括如下重量份的原料：硅橡胶68-132份、补强剂60-70份、硅烷助剂13.6-15.4份、蒸馏水0.3-0.7份、润滑剂0.14-0.22份、增硬剂1-2份、硫化剂0.5-1.5份。本发明的高硬度耐气压硅胶具有较高的硬度，且耐气压性能较好，综合性能优异。
