运用拉伸法研究了硅烷偶联剂对316L不锈钢高分子涂层的结合强度的影响。并对硅烷偶联剂的含量、预处理时间及pH值等工艺条件进行了优化。采用ATRIR,XPS等技术表征了偶联剂提高膜基结合强度的机理。结果表明:硅烷偶联剂能够显著提高不锈钢与高分子涂层之间的结合强度,最佳的工艺条件为:偶联剂含量w=0.05,处理时间为10s,溶液的pH值为6。作用机理是:偶联剂一端与金属生成了Si-O-Me键,另一端与高分子相互缠绕形成了复杂的互穿网络结构。
The influence of silane coupling agent on the bonding strength of 316L stainless steel polymer coating was studied by stretching method. The process conditions of silane coupling agent, pretreatment time and pH value were optimized. ATRIR, XPS and other techniques were used to characterize the coupling agent to improve the film-based bonding strength mechanism. The results show that the silane coupling agent can significantly improve the bonding strength between the stainless steel and the polymer coating. The optimum conditions are as follows: the coupling agent content w = 0.05, the treatment time 10s, the pH value of solution 6. The mechanism of action is: Si-O-Me bond is formed between one side of the coupling agent and the metal, and the other end is intertwined with the polymer to form a complex interpenetrating network structure.
