Concrete waterproof anti-cracking agent and preparation method thereof
The invention discloses a concrete waterproof anti-cracking agent which is characterized in that the concrete waterproof anti-cracking agent is prepared from the following components in parts by weight: 3-6 parts of porous beta-cyclodextrin crosslinked polymer nano-fibers, 10-15 parts of bauxite powder, 4-7 parts of a sulfonic acid group-containing fiber material, 20-30 parts of alunite, 8-12 parts of blast furnace slag, 2-4 parts of rosin-based hyperbranched polyester, 5-10 parts of sulfonate modified 2-amino adenine nucleoside, 3-5 parts of nano-boron fibers, and 2-5 parts of surface hydrophilic pig hair fibers. The invention also provides a preparation method of the concrete waterproof anti-cracking agent. The concrete waterproof anti-cracking agent disclosed by the invention is remarkable in waterproof anti-cracking effect, small in mixing amount, capable of effectively improving the comprehensive performance of concrete and good in environmental protection property.
本发明公开了一种混凝土防水抗裂剂，其特征在于，由如下按重量份计的各组分制成：多孔β‑环糊精交联聚合物纳米纤维3‑6份、铝土矿粉10‑15份、含磺酸基的纤维材料4‑7份、明矾石20‑30份、高炉矿渣8‑12份、松香基超支化聚酯2‑4份、磺酸盐改性2‑氨基腺嘌呤核苷5‑10份、纳米硼纤维3‑5份、表面亲水性猪毛纤维2‑5份。本发明还提供了一种所述混凝土防水抗裂剂的制备方法。本发明公开的混凝土防水抗裂剂防水抗裂效果显著，掺量少，能有效改善混凝土的综合性能，环保性好。
