Anti-corrosion, anti-rust and waterproof anti-cracking agent as well as preparation method and application thereof
The invention discloses an anti-corrosion, anti-rust and waterproof anti-cracking agent as well as a preparation method and application thereof, and belongs to the technical field of concrete admixtures. The anti-cracking agent is prepared from the following raw materials in percentage by mass: 5%-10% of an anti-corrosion and anti-rust component, 15%-20% of a waterproof self-healing component, 50%-60% of an expansion component and 10%-30% of a compaction component, the anti-corrosion and anti-rust component comprises tetrabutylammonium decatungstate and a cathode type anti-rust agent in a mass ratio of (10-20): (80-90), and the cathode type anti-rust agent comprises at least one of zinc phosphate, zinc acetate and calcium zincate. The special anti-corrosion and anti-rust components including the tetrabutylammonium decatungstate, the zinc phosphate and the calcium zincate have excellent anti-corrosion and anti-rust effects; besides, the anti-corrosion and anti-rust component can activate the waterproof self-healing component while improving the anti-corrosion and anti-rust performance, has a promoting effect on the waterproof self-healing component, and can cooperate with the waterproof self-healing component to remarkably improve the secondary anti-permeability performance of the concrete.
本发明公开了一种防腐阻锈防水型抗裂剂及其制备方法和应用，属于混凝土外加剂技术领域。所述抗裂剂的原料包括以下质量百分比的各组分：防腐阻锈组分5％～10％、防水自愈合组分15％～20％、膨胀组分50％～60％、密实组分10％～30％；所述防腐阻锈组分包括质量比为(10～20)：(80～90)的十钨酸四丁基铵和阴极型阻锈剂，所述阴极型阻锈剂包括磷酸锌、醋酸锌和锌酸钙中的至少一种。本发明特定的防腐阻锈组分十钨酸四丁基铵、磷酸锌、锌酸钙，具有优异的防腐阻锈效果；此外，本发明所采用的防腐阻锈组分在提高防腐阻锈性能的同时还能激活防水自愈合组分，对防水自愈合组分具有促进作用，可协同防水自愈合组分显著提高混凝土的二次抗渗性能。
