Preparation method of concrete waterproof additive
The invention relates to a preparation method of a concrete waterproof additive. The preparation method comprises the following steps: A, weighing raw materials in proportion; b, preparing a polyurethane waterproof agent; c, adding slag powder, silicon powder and silicon carbide powder into a ball mill, carrying out ball milling and dispersing for 1-2h, then adding sodium nitrite, calcium oxide and diatomite, and continuously carrying out ball milling and dispersing for 0.2-0.5 h; and D, pouring into stirring equipment after grinding and dispersing, adding a coalescing agent, uniformly mixing,adding a plasticizer while stirring, finally adding a polyurethane waterproof agent and a cross-linking agent, stirring at a high speed until the mixture is viscous, and drying at 105 DEG C to obtainthe concrete waterproof additive. According to the prepared concrete waterproof additive, the waterproof capacity of concrete can be improved, and good strength, corrosion resistance, abrasion resistance and other performance can be guaranteed.
本发明涉及一种混凝土防水添加剂的制备方法，包括以下步骤：A.按比例称取各原料；B.聚氨酯防水剂的制备；C.将矿渣粉、硅粉、碳化硅粉投入球磨机中球磨分散1‑2h，然后投入亚硝酸钠、氧化钙和硅藻土，继续球磨分散0.2‑0.5h；D.研磨分散后倒入往搅拌设备内，加入成膜助剂混合均匀，边搅拌边加入增塑剂，最后加入聚氨酯防水剂和交联剂，高速搅拌至粘稠，105℃烘干，制得混凝土防水添加剂。本发明制备的混凝土防水添加剂，不仅能提升混凝土的防水能力，还能保证较好强度、耐蚀和耐磨等性能。
