一种海洋用钢管桩防护环氧涂料及其制备方法
摘要：
本发明提供了一种海洋用钢管桩防护环氧涂料。该涂料由A、B两部分组成，A、B部分的重量分别以100份计，A部分包括25～50份液体环氧树脂、25～50份填料与1～2.5份偶联剂，B部分包括20～60份改性胺固化剂与2.5～20份带有活性官能团的增韧剂。施工使用时A、B两组份按照环氧基与活泼氢的摩尔量之比为0.8∶1～1.2∶1混合后涂敷在海洋用钢管桩表面，制得的涂层不仅具有良好的防腐性能，而且具有优异的耐冲击强度，对钢管桩具有良好的防护效果。
摘要（英）：

Protective epoxy coating for marine steel pipe piles is provided. The coating comprises an A part and a B part. The A part comprises 25-50 parts by weight of liquid epoxy resin, 25-50 parts by weight of a filler and 1-2.5 parts by weight of a coupling agent. The B part comprises 20-60 parts by weight of a modified amine curing agent and 2.5-20 parts by weight of a flexibilizer with active functional groups. When the coating is used in construction, the A part and the B part are mixed with a mole ratio of epoxy groups to reactive hydrogens being 0.8:1-1.2:1, and then the marine steel pipe piles are coated with the mixture. A prepared coating is good in corrosion resistance and excellent in impact resistance and has good protecting effects for the steel pipe piles.
