Anti-corrosion and anti-rust type anti-crack waterproof agent
The invention discloses an anti-corrosion and anti-rust type anti-crack waterproof agent which comprises the following components in percentage by mass: 25-35% of an anti-corrosion and anti-rust component, 35-55% of an expansion component and 20-30% of a waterproof and anti-seepage component, the anti-corrosion and anti-rust component comprises an anti-corrosion component and an anti-rust component in percentage by mass; AND the anti-corrosion component is any one or more of superfine mineral powder, superfine fly ash and superfine silica fume, and the anti-rust component comprises any one or more of sodium hexametaphosphate, triisopropanolamine, sodium carbonate and anhydrous sodium metasilicate. According to the invention, on the basis of self-waterproofing of a concrete structure with expansion compensation and shrinkage and improved waterproof and impermeable grade, the anticorrosive and rust-resistant admixture is compounded, a proper component proportion is adopted, the expansion reaction rate can be regulated and controlled at 40-60 DEG C, the waterproof and impermeable grade of the concrete is improved, the erosion effect of harmful ions in the environment on the concrete structure is reduced, the three effects of corrosion prevention, rust resistance, water resistance, impermeability and crack resistance are considered, and the engineering application effect is improved.
本发明公开了一种防腐阻锈型抗裂防水剂，以质量百分数计，该防腐阻锈型抗裂防水剂包括防腐阻锈组分25～35％、膨胀组分35～55％、防水抗渗组分20～30％；防腐阻锈组分以质量百分数计包括防腐组分和阻锈组分；防腐组分为超细矿粉、超细粉煤灰、超细硅灰中的任意一种或多种，阻锈组分包括六偏磷酸钠、三异丙醇胺、碳酸钠、无水偏硅酸钠中任意一种或多种。本发明在膨胀补偿收缩、提高防水抗渗等级的混凝土结构自防水基础上，复合了防腐阻锈型外加剂，采用适宜组分比例，能在40～60℃下对膨胀反应速率进行调控，提高混凝土防水抗渗等级，降低环境有害离子对混凝土构筑物的侵蚀作用，兼顾了防腐阻锈、防水抗渗、抗裂三方面效果，提升了工程应用效果。
