The invention relates to the technical field of concrete additives, and discloses a high-strength elastic concrete complexing agent and a preparation process thereof.Modified silicone rubber, a polycarboxylate superplasticizer, silicon dioxide, polyacrylamide, limestone and water are added into a stirrer and stirred, and the high-strength elastic concrete complexing agent is obtained after stirring is finished. The bonding strength between a silicone rubber sealant in the modified silicone rubber and a concrete base material is high, so that the overall stability of a concrete structure is improved, the silicone rubber can improve the flexibility of the concrete and reduce cracks caused by temperature change or load action, and meanwhile, the modified silicone rubber also has relatively good durability; the quaternary ammonium salt group and the sulfonic acid group can enhance the durability of the concrete and prolong the service life of the concrete; and the sulfonic acid group and the polycarboxylic acid water reducing agent jointly form a water reducing agent system.
本发明涉及混凝土添加剂技术领域，且公开了一种高强弹性混凝土的复合剂及其制备工艺，本发明通过将改性硅橡胶、聚羧酸减水剂、二氧化硅、聚丙烯酰胺、石灰石、水加入到搅拌器中，搅拌，结束后得到高强弹性混凝土的复合剂。改性硅橡胶中的硅橡胶密封胶与混凝土基材之间的粘结强度高，这有助于提高混凝土结构的整体稳定性，硅橡胶可以提高混凝土的柔韧性，减少因温度变化或负载作用引起的裂缝，同时也具有较好的耐久性；季铵盐基团和磺酸基团也可以增强混凝土的耐久性，延长其使用寿命；磺酸基团和聚羧酸减水剂共同构成了减水剂体系。
