Macromolecular anti-crack waterproof mortar and preparation method thereof
The invention discloses macromolecular anti-crack waterproof mortar and a preparation method thereof. The macromolecular anti-crack waterproof mortar is prepared from the following raw materials in parts by weight: 100-200 parts of cement, 100-150 parts of sand, 30-50 parts of reinforcing filler, 1-4 parts of a high-efficiency water reducing agent and 100-150 parts of water. In the preparation process, a high-efficiency water reducing agent is prepared, the high-efficiency water reducing agent has a hydrophilic group sulfonic acid group and a hydrophobic group alkyl group, when the high-efficiency water reducing agent is added into cement mortar, cement particles can be dispersed, starch is used as a carrier, the strength of mortar is further improved, the reinforcing filler is prepared, and after the reinforcing filler is mixed with cement, the prepared mixed mortar contains a large number of silicon-oxygen bonds, the silicon-oxygen bonds are long in spacing, large in bond angle and large in bond energy, and polysilane chain segments are soft, so that the surface tension is small, and the mortar has good high temperature resistance and water repellency.
本发明公开了一种高分子抗裂防水砂浆及其制备方法，由如下重量份原料制成：水泥100‑200份、砂100‑150份、增强填料30‑50份、高效减水剂1‑4份、水100‑150份；在制备过程中制备了一种高效减水剂，该高效减水剂具有亲水基团磺酸基和憎水基团烷基，当加入水泥浆体中，能够使得水泥颗粒分散，且淀粉为载体，使得砂浆的强度一步提升，并制备了一种增强填料，该增强填料与水泥混合后，制备的混合砂浆中，含有大量的硅氧键，硅氧键的间距长、键角大、键能大，且聚硅烷链段柔软，使得表面张力小，使得砂浆具有很好的耐高温性和拒水性。
