为了探究附着力促进剂对光固化金属基涂层附着力的影响，本文通过划格法、拉拔法及搭接剪切实验，系统研究了磷酸酯类附着力促进剂、硅烷偶联剂对光固化金属基（低碳钢、铝板）涂层附着力的促进作用。结果表明：磷酸类附着力促进剂能够显著提高光固化金属基（低碳钢、铝板）涂层的附着力，而硅烷偶联剂对光固化金属基（低碳钢、铝板）涂层的附着力无明显提升作用。
In order to explore the effects of adhesion promoters on UV-curable coatings on metal substrates，this paper systematically studied the enhancement of the commonly used commercial adhesion promoters（phosphate ester and silane coupling agents）on the adhesion between UV-cured coatings and different metal substrates（mild steel，aluminum plate）by using various test methods，including the cross-cut，pull-off and lap shear tests to clarify the effect of adhesion promoter on the adhesion of UV-curable metal coatings. The results showed that the adhesion of UV-curable metal coatings was significantly improved by the phosphate ester，while the silane coupling agent indicated no remarkable effect.
