中文摘要:
      目的 研制一种新型硅烷复合物,以替代传统的铬酸盐钝化液对铝材进行表面处理。 方法 将KH-560 和 A-151 两种偶联剂进行复合,并添加合成的水性聚酯水解促进剂和带有活性基团的交联剂 R,考察偶联剂配比、水解促进剂和交联剂 R 的用量对处理液稳定性及硅烷膜耐腐蚀性的影响。 结果 当KH-560 与 A-151 的质量比为 4 : 1 ,水解促进剂的质量分数为 0 . 4% ~ 0 . 6% 时,处理液的储存时间超过90 天,硅烷膜也具有良好的耐腐蚀性能。 对于储存后性能下降的处理液,添加 4% ( 占处理液质量的百分比) 的交联剂 R 后,即能在硅羟基之间形成明显的交联作用,有效增强硅烷膜的防护性能。 结论 该硅烷复合物的综合性能达到了工业化应用要求,可解决铬酸盐钝化液对环境的污染问题,具有良好的社会效益。
英文摘要:
      Objective To develop a new silane compound which can replace the traditional chromate passivation solution in aluminum surface treatment. Methods KH-560 and A-151 were compounded, and self-made waterborne polyester was added as hydrolysis agent together with a crosslinking agent R carrying active groups. The effects of silane agent ratio, dosage of hydrolysis agent and crosslinking agent R on the stability of silane treatment agent and corrosion resistance of silane film were investigated.Results When the ratio of KH-560 and A-151 was 4: 1, and the amount of hydrolysis agent was in the range of 0. 4% ~ 0. 6% , the storage time of treatment agent lasted more than 90 days, and the silane film had good corrosion resistance. For silane treatment agent with performance significantly decreased after long-time storage, demonstrable cross effect in silicon hydroxyl was formed through adding 4% crosslinking agent R, which could effectively enhance the protective properties of silane films. Conclusion The comprehensive properties of silane compound could meet the demands of industrial application, and the problems of environmental pollution by chromate passivation solution could be solved by the use of this new compound, which has good social benefits.
