摘　　要：农业机械常在户外作业,其保护涂层经常受到破坏,因此提高农机涂层与基体的结合性能继而提高其对基体的保护十分重要。采用稀土元素对涂装底漆进行改性是目前涂装领域的一个重要热点,本文通过添加颗粒度不同的稀土氧化物Ce2O3颗粒对底漆进行改性并测试其附着力。结果表明,当添加Ce2O3颗粒的质量百分数为0.1%~0.2%,颗粒度为10~15μm时,漆膜附着力可以达0级,优于常规涂装获得的涂层附着力。Agricultural machinery often works outdoors and its protective coating is often damaged,so it is very important to improve the combination performance of agricultural machinery coating and matrix,and then improve the protective performance of the matrix.The hotspot in the field of coating is to modify the primer by using rare earth elements.In this paper,Ce2O3 with different particle size was added to modify the primer and its adhesion was tested.The results showed when the mass percentage of Ce2O3 was 0.1%~0.2%,the particle size was 10~15μm,the adhesion can reach 0 level,it was superior to the coating performance obtained by conventional coating.
