| 中文摘要: |
| 目的 解决海洋环境复杂钢结构防腐修复难题，提高海洋平台钢结构的使用寿命，保证海洋平台的安全运行。方法 以二羟基聚醚、三羟基聚醚、甲苯二异氰酸酯（TDI）为原料合成了聚氨酯预聚体，对合成反应参数进行了研究，以水固化树脂为基料，研究了水固化涂料的颜填料和助剂。结果 聚氨酯合成的最佳条件为：聚醚多元醇质量比为7:1，合成温度70 ℃，反应时间4 h。添加滑石粉、云母粉、炭黑为填料，二月桂酸二丁基锡为催化剂，填料和催化剂的质量分数分别为10%和0.5%，制备了水固化涂料。该涂料以无纺布为载体，制成了海洋复杂钢结构防腐修复材料。结论 通过对水固化树脂合成条件的优化，确定了树脂合成时二羟基聚醚和三羟基聚醚比例、合成温度、合成反应时间等关键参数，通过对涂料颜填料、助剂的选择，得到了性能较好的水固化涂料，且以无纺布为载体制备了防腐修复材料，可用于海洋复杂钢结构的防腐修复。 |
| 英文摘要: |
| The work aims to solve complex steel structure anti-corrosion repair problems in marine environment, improve service life of steel structures such as offshore platforms and guarantee safe operation of offshore platforms. Polyurethane prepolymer was synthesized from dihydroxy polyether, trihydroxy polyether and toluene diisocyanate (TDI), and the synthesis reaction parameters were studied. On this basis, pigment, filler and additive of water-cured paint were investigated with water-cured resin as base material. Optimum conditions of polyurethane synthesis process were: polyether polyol mass ratio of 7:1, synthesis temperature of 70 ℃ and reaction time of 4 hours. The water-cured paint was prepared with 10% filler consisting of talc, mica powder and carbon black as well as 0.5% catalyst dibutyltin dilaurate. The anticorrosion repair material of marine complex steel structure was prepared with non-woven fabric as carrier. Key parameters including dihydroxy polyether/trihydroxy polyether ratio, synthesis temperature and synthesis reaction time are determined by optimizing synthesis conditions of water-cured resin. Water-cured paint exhibiting better properties is prepared by selecting pigment, filler and catalyst. On this basis, anticorrosion repair material applicable to complex marine steel structure is prepared with non-woven fabric as carrier. |
