Expansion joint rapid repairing material and construction process thereof
The invention relates to the technical field of concrete, and discloses a rapid expansion joint repairing material and a construction technology thereof.The rapid expansion joint repairing material is obtained by adding raw materials into a stirrer and stirring the raw materials evenly; the method comprises the following steps: cleaning loose parts and floating ash of a concrete base surface by using high-pressure water jet, soaking the base surface with water, cleaning after no water is accumulated on the surface, coating a layer of interface agent on the base surface, stirring the materials, paving a thin layer of repairing material, and curing. Polybenzimidazole in the imidazole modified polyurethane has a relatively good compression resistance effect, and can have a synergistic effect with polyurethane which has a proper effect, so that a relatively good proper effect is achieved; in the stirring and mixing process, the terminal isocyanate of the polyurethane reacts with amino groups in the aminated carbon nanotubes to obtain carbamate; the interfacial compatibility of the carbon nanotubes and polyurethane is improved, organic-inorganic hybrid particles are formed, and the compressive effect on the repairing material is achieved together.
本发明涉及混凝土技术领域，且公开了一种伸缩缝快速修补材料及其施工工艺，本发明通过将各组分原料加入到搅拌器中，搅拌均匀，搅拌，得到伸缩缝快速修补材料；用高压水射流将混凝土基面的松散部分和浮灰处理干净，用水浸泡基面，表面无积水后清扫，然后在基面上涂刷一层界面剂，然后搅拌材料、摊铺薄层修补材料、养护即可；咪唑修饰聚氨酯中的聚苯并咪唑具有较好的抗压效果，会和本身就具有可以效果的聚氨酯协同作用，起到较好的可以效果；并且在搅拌混合的过程中聚氨酯的端异氰酸酯会和氨基化碳纳米管中的氨基进行反应，得到氨基甲酸酯；提高了碳纳米管和聚氨酯的界面相容性，形成有机‑无机杂化粒子，共同起到对修补材料的抗压效果。
