High-strength environment-friendly antirust slurry for exposed reinforcing steel bars in bridge engineering and preparation method of high-strength environment-friendly antirust slurry
The invention discloses high-strength environment-friendly anti-rust slurry for exposed reinforcing steel bars in bridge engineering and a preparation method. The high-strength environment-friendly anti-rust slurry comprises a composite material, an early setting agent, polyaniline, a corrosion inhibitor, vinyl silane, chlorinated polypropylene and water, the coating is specifically prepared from the following components in parts by weight: 50 to 60 parts of a composite material, 0.01 to 0.05 part of an early setting agent, 1 to 2 parts of polyaniline, 0.5 to 1.5 parts of a corrosion inhibitor, 5 to 15 parts of vinyl silane, 8 to 12 parts of chlorinated polypropylene and 45 to 55 parts of water. According to the invention, polyaniline and free electrons on the surface of the reinforcing steel bar are utilized to form an electric field effect, the binding power between the reinforcing steel bar and concrete is improved, and a three-phase interface of the reinforcing steel bar, slurry and cement is improved, so that the interface has the flexibility of polymer slurry and the rigidity of cement, and the equilibrium boundary point between the binding power and the anti-rust property is optimized; polyaniline is modified through vinyl silane and chlorinated polypropylene, the film forming performance and adhesive force of the anti-rust slurry are further improved, contact between water vapor and the surface of the reinforcing steel bar is effectively blocked, and therefore corrosion of the reinforcing steel bar is prevented.
本发明公开了一种桥梁工程中外露钢筋高强度环保防锈浆及配制方法，包括复合材料、早凝剂、聚苯胺、阻锈剂、乙烯基硅烷、氯化聚丙烯和水；其具体配制，按重量份数，包括以下组分：复合材料50‑60份、早凝剂0.01‑0.05份、聚苯胺1‑2份、阻锈剂0.5‑1.5份、乙烯基硅烷5‑15份、氯化聚丙烯8‑12份和水45‑55份。本发明利用聚苯胺与钢筋表面自由电子形成电场作用，提升钢筋与混凝土之间的粘结力，通过改善钢筋、浆料、水泥三相界面，使界面兼具聚合物浆料的柔性与水泥的刚性，从而优化粘结力与防锈性之间的平衡界点；通过乙烯基硅烷、氯化聚丙烯对聚苯胺进行改性，进一步提高防锈浆料的成膜性能和附着力，有效地阻隔水气与钢筋表面接触，从而阻止钢筋锈蚀。
