This invention pertains to a method of modifying polymeric coating materials by adding organosulfur compounds, so that the metallic substrates coated with the modified polymeric materials become more resistant to corrosion. The organosufur compounds are alkane thiols with a general formula R(CH2)nSH, where R represents H, NH2, HOOC, and HO groups and n is in the range of 10 to 21. The reagents are designed to increase the adhesion between the polymeric coating materials and the metallic substrates, which may be conducive to increased corrosion resistance.
本发明涉及一种通过添加有机硫化合物对聚合涂层材料进行改性的方法,从而使涂有改性聚合材料的金属基材具有更强的抗腐蚀性。有机硫化合物是烷硫醇,通式为 R(CH2)nSH,其中 R 代表 H、NH2、HOOC 和 HO 基团,n 在 10 到 21 之间。这些试剂旨在增加聚合物涂层材料与金属基材之间的附着力,从而有利于提高耐腐蚀性。
