Rapid crack self-repairing agent for maritime work reinforced concrete and preparation method of rapid crack self-repairing agent
The invention discloses a rapid crack self-repairing agent for maritime work reinforced concrete and a preparation method of the rapid crack self-repairing agent. The self-repairing agent comprises the following components in percentage by mass: 20-30% of polyacrylic acid hydrogel, 5-10% of microorganisms, 20-30% of betaine, 15-25% of calcium salt and 20-30% of aluminum salt. The preparation method comprises the following steps: mixing the acrylic monomer with the cross-linking agent, the initiator and the auxiliary cross-linking agent; mixing aluminum salt and acrylic acid to obtain aluminum acrylate; mixing the microbe-polyacrylic acid hydrogel with the microbe and betaine, stirring and heating to prepare microbe-polyacrylic acid hydrogel; and drying, crushing, coating calcium salt powder, dipping in polymer emulsion, and drying to obtain the product. By forming an organic-inorganic composite repairing product, cracks can be quickly blocked, harmful media are cured, beneficial ions are released, and the dual purposes of crack self-repairing and steel bar corrosion inhibition are achieved.
本发明公开了一种海工钢筋混凝土用裂缝快速自修复剂及其制备方法，该自修复剂按质量分数包含以下组分：聚丙烯酸水凝胶20‑30％、微生物5‑10％、甜菜碱20‑30％、钙盐15‑25％、铝盐20‑30％。其制法为：将丙烯酸单体与交联剂、引发剂、辅助交联剂混合；将铝盐、丙烯酸混合得丙烯酸铝；将前述两者与微生物和甜菜碱混合，搅拌加热，制得微生物‑聚丙烯酸水凝胶；干燥后破碎，包裹钙盐粉末，再浸渍于聚合物乳液，干燥，制得。本发明通过形成有机‑无机复合修复产物，可快速封堵裂缝，同时固化有害介质，释放有益离子，实现裂缝自修复和钢筋腐蚀抑制的双重目标。
