摘要:

通过附着力、中性盐雾、耐磨性、紫外老化、循环腐蚀和户外暴露实验等研究了6种不同涂料体系的防护性能，分析了它们在海上型风力发电系统涂装的可行性。结果表明：S03和S04两种环氧富锌聚氨酯涂层体系在循环腐蚀以及户外挂片实验后仍具有5 MPa以上的附着力；P04和P06两种富锌底漆锈蚀和起泡等级均为1级 (S2)，且锈蚀蔓延宽度不超过2.70 mm，具有较好的耐盐雾腐蚀和抗腐蚀扩展性能；T01~T04和T06共5种聚氨酯面漆的耐磨性均大于1.0 L/μm，具有优良的耐磨性；紫外加速老化过程中，T01~T04这4种聚氨酯面漆失光率均未超过1级，具有较好的耐紫外老化和耐腐蚀性能。不同厂家同类型油漆在防护性能上仍存在较大差距，S04涂层体系具有较好的综合防护性能，推荐用于海上风力发电系统的涂装防腐。

Abstract：

The feasibility of several coating systems for offshore wind power generation system was assessed through adhesion measurement, neutral salt spray, wear resistance test, ultraviolet aging test, cyclic corrosion test and outdoor exposure test. Experimental results indicated that after cyclic corrosion and outdoor exposure test, two types of epoxy zinc-rich polyurethane coating systems S03 and S04 maintained adhesive strength of above 5 MPa. After neutral salt spray test for 2000 h, the rust- and blister-degree for the two zinc-rich primers P04 and P06 could be raked as grade 1 (S2), while the expand of the rust size is no more than 2.70 mm underneath the primer. Hence, the two primers have good resistance to salt spray and corrosion propagation. Five types of polyurethane coatings, including T01~T04 and T06, have excellent wear resistance of superior to 1.0 L/μm. The gloss reduction of four types of polyurethane coatings (T01~T04) did not exceed grade 1 during the course of uv-accelerated aging. However, there exists large variations in the protective performance for the same type of paint supplied by different manufacturers. It is concluded that the S04 coating system has better comprehensive protective performance, thus, which is suitable to the application in the sector of offshore wind power generation system.

Key words： offshore wind power generation coating system
