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

6-尼龙树脂（PA 6）在注塑过程中直接粘附到涂有三嗪三硫醇聚合物（TTP）的不锈钢（SUS）板上。在SUS板上通过电聚合1，3，5-三嗪-2，4-二硫醇-6-硫醇钠形成TTP涂层。PA 6与SUS板之间的粘合剂具有6 MPa以上的高剪切强度。通过X射线光电子能谱（XPS）分析，以及均三嗪三硫醇化学氧化法（CO-TTP）制备的TTP与胺和尼龙低聚物的模型反应，研究了TTP在SUS板上的附着机理。XPS分析结果表明，TTP在SUS和TTP涂层界面形成了硫醇铁或硫醇铬。CO-TTP与胺反应得到氨基三嗪硫醇衍生物。在220 [encircledA]e处与CO-TTP捏合的尼龙低聚物的NMR谱中，与末端氨基相邻的亚甲基的质子信号消失。粘附的机理被解释为在PA 6和TTP涂层的界面处形成化学键，其通过PA 6中的末端氨基的亲核取代而化学键合到SUS。适用于高气密性电解电容器端子、汽车气密连接器等封装件。他们用气压进行了泄漏试验。证实了它们的实用性。有机镀覆能够在铝板上形成三嗪硫醇膜。通过三嗪硫醇与聚苯硫醚树脂的有机镀，使铝板直接粘接成为可能。本研究之结果考虑了汽车零组件、笔记本电脑等多用途之轻量化应用。作为一种新的工业技术，该技术的实际应用研究是非常有希望的。

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.
