项目摘要

6-Nylon resin (PA6) directly adhered to stainless steel (SUS) plates coated with triazine trithiol polymer (TTP) during injection-molding. TTP coating on the SUS plates was formed by electropolymerization of 1,3,5-triazine-2,4-dithiol-6-sodium thiolate in aqueous solution. Adherends between PA6 and the SUS plates had high shearing strengths of 6MPa or more. The adhesion mechanism was investigated by X-ray photoelectron spectroscopic (XPS) analyses of TTP coating on the SUS plates and model reactions of TTP prepared from s-triazine trithiol by chemical oxidation (CO-TTP) with amines and nylon oligomer. The result of XPS analyses showed that TTP formed iron or chromium mercaptide at the interfaces of SUS and TTP coating. The reactions of CO-TTP with amines gave amino triazine thiol derivatives. In NMR spectra of nylon oligomer kneaded with CO-TTP at 220 【encircledA】e, the proton signal of methylene adjacent to terminal amino group disappeared. The mechanism of adhesion was explained to be a formation of chemical bonds at the interface of PA6 and TTP coating, which chemically bonded to SUS by the nucleophilic substitution of terminal amino groups in PA6. It was applied to encapsulation parts such as terminal of the high airtight electrolytic capacitor and airtight connector for the automobile. They carried out the leakage test by air pressure. It was confirmed that there was a practicability on them. The organic plating was able to form a triazine thiol film on the aluminum plate. The direct adhesion of aluminum plate by the organic plating of triazine thiol and polyphenylene sulfide resin became possible. The application of versatile such as car component and notebook-sized personal computer for the lightening is considered by the result of this study. The this practical application research is very much expected as a new industrial technology.

6-尼龙树脂（PA6）在注塑过程中直接粘附在涂有三嗪三硫醇聚合物（TTP）的不锈钢（SUS）板上。采用1,3,5-三嗪-2,4-二硫醇-6-硫代酸钠在水溶液中电聚合的方法在SUS板上形成TTP涂层。PA6与SUS板之间的黏附物具有6MPa以上的高剪切强度。利用x射线光电子能谱（XPS）分析了TTP涂层在SUS板上的粘附机理，并模拟了s-三嗪三硫醇与胺和尼龙低聚物化学氧化法制备TTP的反应。XPS分析结果表明，TTP在SUS和TTP涂层的界面形成了铁或铬巯基。CO-TTP与胺反应得到氨基三嗪硫醇衍生物。在220【环合da】e下与CO-TTP共揉尼龙低聚物的核磁共振谱中，末端氨基附近亚甲基的质子信号消失。吸附机理为PA6与TTP涂层界面形成化学键，通过PA6末端氨基的亲核取代与SUS形成化学键。应用于汽车用高气密性电解电容器端子、气密连接器等封装件。他们用气压进行了泄漏试验。这证实了它们的实用性。有机镀层能够在铝板上形成三嗪硫醇薄膜。用三嗪硫醇和聚苯硫醚树脂有机电镀直接粘附铝板成为可能。本研究的结果考虑了汽车部件和笔记本大小的个人电脑等多功能的照明应用。这一实际应用研究作为一项新的工业技术备受期待。
