- 摘要:
- 农机多是在在户外作业，恶劣环境下易发生腐蚀。本文采用常用涂装体系，在环氧涂料中添加稀土氧化物Y2O3对其改性作为底漆，并以丙烯酸聚氨酯涂料作为面漆，选择磷化、锈蚀钢板与丙烯酸聚氨酯涂层作为基体，进行涂装。结果表明，添加Y2O3后涂层附着力、耐腐蚀性能与抗老化性能明显提升。
- Abstract:
- The agricultural machinery is prone to corrosion because of bad service environment. In this paper, the commonly used coating system was adopted. The epoxy coating was modified by adding rare earth oxide Y2O3 as the primer, and the acrylic polyurethane coating was used as the topcoat. The phosphating, rusting steel plates and acrylic polyurethane coatings were chosen as the matrix for coating. The results showed that after the addition of Y2O3, the adhesion, corrosion resistance and antiageing performance were improved significantly.
