Concrete corrosion-resistant internal curing agent as well as preparation method and application thereof
The invention discloses a concrete corrosion-resistant internal curing agent as well as a preparation method and application thereof, and belongs to the technical field of concrete admixtures. The preparation method comprises the following steps: S1, adding a load component and water into a container, carrying out ultrasonic homogenization, adding a healing component, and stirring at 30-45 DEG C to obtain a primary product A; s2, adding super absorbent resin into the primary product A, uniformly dispersing, adding an inorganic rust-inhibiting component, heating to 45-55 DEG C, and uniformly stirring in a protective gas atmosphere to obtain an intermediate product B; and S3, adding an organic rust-inhibiting component into the intermediate product B, uniformly stirring at 45-55 DEG C in a protective gas atmosphere, then heating to 55-65 DEG C, continuously stirring, and dehydrating and drying to obtain the product. The internal curing agent prepared by the preparation method disclosed by the invention has self-curing, self-healing and rust-inhibiting functions, and has a long-term slow-release effect; cracks generated in the concrete service process can be effectively resisted and bridged, the self-healing function is achieved, corrosion of corrosive ions is prevented, and the durability of the concrete is improved.
本发明公开了一种混凝土阻锈型内养护剂及其制备方法和应用，属于混凝土外加剂技术领域。所述制备方法包括以下步骤：S1.在容器中加入负载组分和水，超声均化，加入愈合组分后在30～45℃下搅拌，得到初级产物A；S2.在初级产物A中加入高吸水树脂，分散均匀后加入无机阻锈组分，升温至45～55℃，在保护气体氛围下搅拌均匀，得到中级产物B；S3.在中级产物B中加入有机阻锈组分，在45～55℃、保护气体氛围下搅拌均匀，然后升温至55～65℃，持续搅拌，经脱水干燥后即得。本发明制备方法制备的内养护剂同时具备自养护、自愈合和阻锈功能，且具有长期缓释效果；可有效抵御弥合混凝土服役过程中产生的裂缝，发挥自愈合功能，阻止腐蚀离子的侵蚀，提高混凝土的耐久性。
