| 摘 要： | 利用砂纸打磨、酸冼、磷化、喷砂、KH-560硅烷处理等不同表面预处理工艺对Q235钢基体进行预处理。并在不同表面状态的钢基体上制备聚乙烯涂层，研究了不同预处理工艺对聚乙烯涂层结合强度的影响。结果表明：传统表面处理工艺提高涂层结合强度有限，而KH-560硅烷处理可以显著提高涂层结合强度，较用传统的砂纸打磨（60^#）、酸冼、磷化、喷砂处理工艺分别提高了40．3％、46％、17．6％和13．2％，而涂层的破断形式也有别于传统的处理方法，为内聚断裂；“喷砂＋KH-560”预处理法可以获得最大的涂层结合强度。

| Abstract: | Polyethylene coatings was applied on Q235 steel substrate surface with different surface conditions pretreated by sandpaper grinding, acid etching, phosphating, blasting and KH -560 respectively, and the effect of various pretreatments on the adhesive strength of polyethylene coatings was investigated in this paper. The results showed that the traditional pretreatments had a limited improvement for the adhesive strength, but KH -560 pretreatment can increased adhesive strength significantly which was higher than those with sandpaper grinding, acid etching, phosphating, and blasting by 40. 3%, 46%, 17.6% and 13.2% respectively, and that the highest adhesive strength can be obtained when the substrates were pretreated by the blend pretreatment of blasting and KH -560. |
