Abstract
It focused on how the low carbon steel surface was pretreated by hydrolyzed KH-560 silane solution and the polyethylene (PE) coatings were prepared on the pretreated surface in the paper. Moreover, the comparison of the adhesive strengths of PE coatings has been made between the coating and the steel substrate surfaces pretreated by silane agents and other various conventional pretreatment methods. The results show that the highest adhesive strength between coatings and steel surface could be acquired on the condition that the concentration of KH-560 was about 5% and the hydrolytic time was 48 hours, and the adhesive strength of coatings coated on the steel substrate surfaces pretreated by silane agents was more or less higher than those pretreated by conventional processes such as sandpaper grinding, acid etching, phosphating and sandblasting by 40.3%, 46%, 17.6% and 13.2%, respectively. The fracture morphology of the coatings coated on silane agent pretreated substrate surface showed cohesive failure, which was also different from the ones coated on the conventional process pretreated substrate surfaces.
