Liquid inorganic material for crack reinforcement and preparation method thereof
The invention discloses a liquid inorganic material for crack reinforcement and a preparation method thereof. The liquid inorganic material is prepared by mixing component A liquid and component B liquid according to the mass ratio of (2-4): 1, the component A liquid comprises the following components in parts by mass: 75-90 parts of an adhesive, 30-50 parts of diatomite and 1-5 parts of a stabilizer, and the pH value of the component A liquid is 7-9 after mixing; the component B liquid comprises the following components in parts by mass: 10-20 parts of waste phosphoric acid, 50-150 parts of water and 30-100 parts of inorganic salt, and the pH value of the component B liquid is 1-1.5 after mixing; in addition, according to the size of cracks and the total amount of injected materials, a proper amount of superfine steel fibers are added to improve the strength after solidification; after being injected into a crack and solidified, the grouting material has high strength, controllable gelling time, low solidification reaction temperature and strong binding power, so that the grouting material has relatively good durability; in addition, on-site preparation is not needed, and therefore the good injection efficiency is achieved; in addition, the method is suitable for mine and is also suitable for crack reinforcement in industries of buildings, roads, bridges and the like.
本发明公开了一种用于裂缝加固的液体无机材料及其制备方法，包括A组分液体和B组分液体按照质量比为(2～4):1混合制成；A组分液体按照质量份数为：胶粘剂75～90份、硅藻土30～50份和稳定剂1～5份，混合后使A组分液体的pH值为7～9；B组分液体按照质量份数为：废磷酸10～20份、水50～150份以及无机盐30～100份，混合后使B组分液体的pH值为1～1.5；另外根据裂缝大小及注入材料总量情况，适量添加超细钢纤维提高凝固后的强度；本发明注入裂缝凝固后具有高强度，且胶凝时间可控、凝固反应温度低、粘结力强，从而具有较好的耐久性；并且无需现场制备，从而具有较好的注入效率；另外其不仅适用于矿山，还适用于建筑、路桥等行业的裂缝加固。
