低粘度高性能混凝土结构快速修补剂
摘要：
本发明涉及一种低粘度高性能混凝土结构快速修补剂及其制备方法，属化学建筑材料领域。组分1：甲基丙烯酸甲酯，100份；组分2：甲基丙烯酸丁酯，28～35份；组分3：过氧化苯甲酰，3.0～3.8份；组分4：环氧树脂，15～20份；组分5：KH-570，10～19份；组分6：甲基丙烯酸，3.5～4.0份；组分7：二甲基苯胺，0.8～1.2份；组分8：无机填料，0～20份。本发明除保留“甲凝”修补材料所固有的低粘度高渗透性外，还具有较高的力学强度，较低的收缩率以及良好的耐久性能。能满足混凝土结构微细裂缝快速修补的要求。
摘要（英）：

The invention relates to a quick healant with low viscosity and high performance for a concrete structure, belonging to the field of chemical building materials. The quick healant comprises eight components of 100 parts of methyl methacrylate, 28-35 parts of butyl methacrylate, 3.0-3.8 parts of benzoyl peroxide, 15-20 parts of epoxy resin, 10-19 parts of KH-570, 3.5-4.0 parts of methacrylic acid,0.8-1.2 parts of dimethylaniline and 0-20 parts of inorganic filler. The invention not only retains the low viscosity and the high permeability of a polymethyl repairing material, but also has highermechanical strength, lower shrinking rate and favorable durable performance. In addition, the invention can meet the requirement for rapidly repairing microscopic checks of the concrete structure.
