Steel bar corrosion inhibitor for marine concrete and preparation method thereof
The invention discloses a steel bar corrosion inhibitor for marine concrete and a preparation method of the steel bar corrosion inhibitor. The corrosion inhibitor is prepared from 30 to 50 parts of N,N-dimethyl ethanolamine, 20 to 30 parts of polycarboxylic acid terpolymer, 5 to 10 parts of 2-phenylimidazoline quaternary ammonium salt, 10 to 15 parts of hydroxide, 1 to 5 parts of water-based polyaniline, 2 to 5 parts of polyol phosphate and 40 to 60 parts of water, and the pH value is 11 to 13.5. The concrete reinforcing steel bar corrosion inhibitor has good retaining performance for concrete structures, has efficient reinforcing steel bar corrosion inhibition performance, and can be applied to reinforced concrete structures such as harbor engineering, coastal buildings and civil buildings.
本发明公开了一种用于海工混凝土的钢筋阻锈剂及其制备方法，该阻锈剂包括30‑50份N，N‑二甲基乙醇胺、20‑30份聚羧酸三元共聚物、5‑10份2‑苯基咪唑啉季铵盐、10‑15份氢氧化物、1‑5份水性聚苯胺、2‑5份多元醇磷酸酯、40‑60份水，pH为11‑13.5。本发明的混凝土钢筋阻锈剂对混凝土结构有良好的保持性，且具有高效的钢筋阻锈性能，可应用于海港工程、沿海建筑、民用建筑等钢筋混凝土结构。
