Microcapsule for self-repairing concrete and preparation method thereof
The invention relates to a microcapsule for self-repairing concrete and a preparation method thereof, and relates to the technical field of concrete repairing materials, the preparation method comprises the following steps: heating a wall material to obtain a liquid wall material; adding the core material into the liquid wall material, heating and stirring, adding the cooling liquid, and continuously stirring to obtain a microcapsule suspension; carrying out ultrasonic dispersion on the microcapsule suspension, and then filtering and drying to obtain the microcapsule for the self-repairing concrete, the wall material comprises at least one of polyethylene wax, paraffin and nano silicon dioxide; and the core material comprises a diisocyanate compound. According to the invention, polyethylene wax, paraffin and nano silicon dioxide are taken as wall materials, a diisocyanate compound is taken as a core material, and the microcapsule for self-repairing concrete, which has proper mechanical property, excellent sealing property and good self-repairing effect, is prepared by a melting, dispersing and condensing method, so that the defects in the prior art are overcome.
本发明涉及一种自修复混凝土用微胶囊及其制备方法，涉及混凝土修复材料技术领域，所述制备方法包括以下步骤：将壁材进行加热，得到液态壁材；将芯材加入所述液态壁材中进行加热搅拌，后加入冷却液继续搅拌，得到微胶囊悬浮液；将所述微胶囊悬浮液进行超声分散，后进行过滤和干燥，得到所述自修复混凝土用微胶囊；所述壁材包括聚乙烯蜡、石蜡和纳米二氧化硅中的至少一种；所述芯材包括二异氰酸酯类化合物。本发明以聚乙烯蜡、石蜡和纳米二氧化硅为壁材和二异氰酸酯类化合物为芯材，通过熔化分散冷凝法制备得到具有适宜的力学性能、优良密封性和自修复效果佳的自修复混凝土用微胶囊，弥补了现有技术的不足。
