摘　　要：通过对两种分子量的环氧树脂底漆进行试验研究,探讨了固化剂类型,基材种类以及附着力促进剂对其附着力的影响。结果表明,不同固化剂体系涂膜附着力的优异程度为:环氧聚氨酯体系>环氧聚酰胺体系(大分子聚酰胺)>环氧聚酰胺体系(小分子聚酰胺)>环氧改性脂环胺体系。对常见的基材体系研究表明,在硫酸阳极化处理过的铝板上,环氧底漆附着力表现最为优异。加入附着力促进剂,会一定程度上改善漆膜附着力,并且在同种基材上其附着力的表现也存在差异。In this paper,the effects of curing agent type,substrate type and adhesion promoter on the adhesion of epoxy resin primers with two molecular weights were studied.The results show that different curing agent system,the excellent degree of adhesion of paint film is:epoxy polyurethane system>large molecular weight epoxy polyamide system≥small molecular weight epoxy polyamide system≥epoxy modified lipopyclic amine system.For common base material systems,the study showed that the adhesion of epoxy primer was the best on anodized sulfuric acid aluminum plate.The adhesion of the paint film can be improved to a certain extent by adding adhesion promoter,and the performance of the adhesion on the same substrate is also different.
