Self-healing anti-freezing rust-inhibiting anti-cracking agent as well as preparation method and application thereof
The invention discloses a self-healing anti-freezing rust-inhibiting anti-cracking agent as well as a preparation method and application thereof. The anti-cracking agent comprises the following components in parts by weight: 10-20 parts of sodium silicate, 1-5 parts of a reaction accelerator, 5-10 parts of an anti-freezing compacting agent, 1-5 parts of a corrosion inhibitor, 5-10 parts of an ion complexing agent, 5-10 parts of a waterproof agent, 1-5 parts of a surfactant and 30-65 parts of deionized water. The anti-freezing compacting agent disclosed by the invention selects modified nano aluminum oxide, and after being grafted with ethylene glycol, the anti-freezing compacting agent has the anti-freezing performance of ethylene glycol. The anti-cracking agent disclosed by the invention has the properties of freezing resistance, rust resistance, cracking resistance, strong seepage force, good impermeability, self-repairing and the like, can achieve the optimal compact anti-cracking effect aiming at concrete with different porosity conditions, and is simple in preparation method, low in cost, free of pollution and convenient to apply in the concrete.
本申请公开了一种自愈合型防冻阻锈抗裂剂及其制备方法和应用。所述抗裂剂包括以下重量份的组分：硅酸钠10～20份、反应促进剂1～5份、防冻密实剂5～10份、阻锈剂1～5份、离子络合剂5～10份、防水剂5～10份、表面活性剂1～5份、去离子水30～65份。本发明防冻密实剂选用改性纳米氧化铝，接枝乙二醇后，兼备乙二醇的防冻性能。本发明的抗裂剂具有防冻、阻锈、抗开裂、渗透力强、抗渗性好、自修复等性能，可针对不同孔隙率状况的混凝土达到最优的密实抗裂效果，且制备方法简单，成本低，无污染，在混凝土中应用方便。
