Concrete thin-layer repairing polymer mortar and preparation method thereof

The invention provides concrete thin-layer repairing polymer mortar and a preparation method thereof and relates to the field of mortar. The concrete thin-layer repairing polymer mortar is prepared from the following raw materials in weight ratio: two-component slow reaction type polyurea waterproof coating and a sand material, wherein the weight ratio of the two-component slow reaction type polyurea waterproof coating to the sand material is 1:(1-3). By utilizing the concrete thin-layer repairing polymer mortar, the problem that polymer mortar in the prior art cannot well repair a concrete building component can be solved, and the concrete thin-layer repairing polymer mortar has the advantages of good bonding performance, corrosion resistance and scour and wear resistance. 本发明提供了种混凝土薄层修复聚合物砂浆及其制备方法，涉及砂浆领域，该混凝土薄层修复聚合物砂浆包括以下重量比的原料：双组份慢反应型聚脲防水涂料：砂料＝1:(1～3)。利用该混凝土薄层修复聚合物砂浆能够缓解现有技术中的聚合物砂浆均不能很好地做到修复混凝土建筑构件的问题，该混凝土薄层修复聚合物砂浆具有粘结性能、抗侵蚀性和抗冲磨性好的优点。
