Permeable inorganic cement-based material surface crack repairing coating and preparation method thereof
The invention discloses a permeable inorganic cement-based material surface crack repairing coating and a preparation method thereof. The crack repairing coating comprises the following components in parts by weight: 5-15 parts of aluminum triphosphate, 5-10 parts of sodium citrate, 100 parts of an alkaline silicate solution with the solid content of 28-32%, 4-10 parts of silicon dioxide and 33 parts of water. The crack repairing coating is low in raw material price, low in manufacturing cost, simple in preparation method, simple and convenient to construct, green and low in carbon, the gelation time and permeability of a repairing material can be balanced, and the crack area repairing rate is increased. The preparation method of the repairing coating is simple in technological process, low in manufacturing cost and easy and convenient to construct, and the crack repairing coating which is short in gelation time and high in cement-based material crack area repairing rate can be prepared.
本发明公开了一种渗透型无机水泥基材料表面裂缝修补涂料及制备方法，本发明中裂缝修补涂料按重量份计包括：5‑15份三聚磷酸铝，5‑10份柠檬酸钠，100份固含量为28‑32％的碱性硅酸盐溶液，4‑10份二氧化硅，33份水。本发明中的裂缝修补涂料，原料价格低廉、制作成本低，制备方法简单，施工简便，绿色低碳，能够平衡修补材料的凝胶时间与渗透性，提高裂缝面积修复率。本发明中修补涂料的制备方法工艺流程简单，制作成本低，施工简便，能够制备得到凝胶化时间短、水泥基材料裂缝面积修复率高的裂缝修补涂料。
