The practical application research of the direct adhesion of plastic and metal.

6-尼龙树脂(PA6)在注塑成型过程中直接粘接在涂有三嗪三硫醇聚合物(TTP)的不锈钢(SUS)平板上。通过1，3，5-三氮-2，4-二硫醇-6-硫酸钠在水溶液中的电聚合，在SUS平板上形成了TTP涂层。尼龙6与SUS板材之间的粘结剂具有6 Mpa以上的高剪切强度。通过X射线光电子能谱(XPS)分析SUS平板上的三聚氰胺涂层，以及S-三氮杂三硫醇化学氧化制备三聚体(CO-TTP)与胺和尼龙低聚物的模型反应，研究了三聚体的粘接机理。XPS分析结果表明，TTP在SUS和TTP涂层的界面形成了铁或铬硫化物。CO-TTP与胺反应生成氨基三嗪硫醇衍生物。在与CO-TTP共混的尼龙低聚物的核磁共振谱中，末端氨基附近的亚甲基质子信号消失了。粘接机理解释为PA6与TTP涂层界面形成化学键，通过PA6中末端氨基的亲核取代与SUS发生化学键合。应用于高密封性电解电容器端子、汽车密封性连接器等封装件。他们用气压进行了泄漏试验。证实了它们的实用性。有机电镀能够在铝板上形成一层三氮杂硫醇薄膜。通过三氮杂硫醇和聚苯硫醚树脂的有机电镀实现了铝板的直接粘接。根据本研究的结果，考虑了汽车部件和笔记本电脑等多功能产品在照明方面的应用。这项实际应用研究作为一项新的工业技术是非常值得期待的。

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.
