Microcapsule type corrosion inhibitor and preparation method thereof
The invention belongs to the technical field of concrete reinforcement corrosion inhibition, and particularly discloses a microcapsule type corrosion inhibitor which comprises polystyrene-based corrosion inhibitor microcapsules and nanoparticles attached to the microcapsules. Wherein the microcapsule comprises a hollow shell with a polystyrene-based component and a corrosion inhibitor wrapped in the hollow shell. The microcapsule type corrosion inhibitor can improve the durability of concrete, prolong the service life of the concrete, enhance the wear resistance of the concrete and reduce the wear in the use process. The invention also discloses a preparation method of the microcapsule type corrosion inhibitor, which comprises the following steps: firstly preparing a polystyrene mixture to obtain a hollow shell of a polystyrene-based component, and then under the action of a silane coupling agent and an emulsifier, wrapping the corrosion inhibitor in the hollow shell and attaching the corrosion inhibitor to gaps on the surfaces of particles of a nano material; the small-size effect and the surface effect of a nano material are fully exerted, and the obtained microcapsule type corrosion inhibitor has a corrosion inhibiting effect and a repairing effect at the same time.
本发明属于混凝土钢筋阻锈技术领域，尤其公开了一种微胶囊型阻锈剂，其包括聚苯乙烯基‑阻锈剂微胶囊、以及附着在该微胶囊上的纳米颗粒；其中，该微胶囊包括聚苯乙烯基组分的中空壳体和被包裹在内部的阻锈剂。该微胶囊型阻锈剂可提高混凝土的耐久性，延长混凝土的使用寿命，还可以增强混凝土的耐磨性，减少使用过程中的磨损。本发明还公开了该微胶囊型阻锈剂的制备方法，通过先行制备聚苯乙烯混合物，获得聚苯乙烯基组分的中空壳体，继而在硅烷偶联剂和乳化剂的作用下，将阻锈剂包裹在其内并附着于纳米材料的颗粒表面的空隙处；不仅充分发挥了纳米材料的小尺寸效应和表面效应，还可使获得的微胶囊型阻锈剂兼具有阻锈作用和修复作用。
