The invention relates to the technical field of silica gel, in particular to high-elongation silica gel and a preparation method thereof. The high-elongation silica gel is prepared from raw materials in parts by weight as follows: 90-110 parts of silicone rubber, 48-52 parts of a reinforcing agent, 3.8-4.6 parts of a silane aid, 4.0-4.4 parts of filler, 0.15-0.25 parts of a lubricant and 0.5-1.5 parts of a vulcanizing agent. The high-elongation silica gel has higher elongation and excellent overall performance. 本发明涉及硅胶技术领域，具体涉及种高伸长率硅胶及其制备方法，所述高伸长率硅胶包括如下重量份的原料：硅橡胶90-110份、补强剂48-52份、硅烷助剂3.8-4.6份、填充剂4.0-4.4份、润滑剂0.15-0.25份、硫化剂0.5-1.5份。本发明的高伸长率硅胶具有较高的伸长率，综合性能优异。
