项目摘要

The presented direct adhesion technique between metals and rubbers is practically and theoretically worth producing rubber-metal adherends without adhesive by using nickel-plated metals and rubber compounds with triazine thiols. The purpose of this study is to elucidate the effect of surface compositions of nickel plating and curing system on adhesion, and contract direct adhesion mechanism between rubbers and metals during curing.1) Nickel plated metals increased the thickness of oxide layrs in air exposure and over 20* thick, did not adhere with rubber compounds under conventional curing conditions. In these cases, the plating surface was covered with nickel hydroxide which does not produce interfacial bonds between rubber molecules and nickel surface or nickel reaction products, and changed to non-adhesive surface.2) Conventional compounds such as NR,CR,NBR,HS-NBR,EPDM,FR,AR adhered to nickel plated metals by the addition of triazine thiols during curing. The good adhesion and prope … More rties of vulcanizates was obtained by controling the ratio of triazine thiols and key accerelators. In the peroxide curing system, good balance was obtained in the presence of triazine thiols.3) Direct adhesion between rubber compounds and nickel plated metals during curing is explained as follows. In this adhesion, the difference of chemical potential between rubber compounds and nickel plated metals is formed when both come to contact. The difference of chemical potential brings about the reactions of nickel ions with triazine thiols or gradients ; nickel ions come to diffuse from nickel plating. The reactions lead to the formation of interfacial bonds and reinforcement layr at interface between vulcanizates and nickel plating ; the bonds and layr was determined from interfacial analysis. Both formation is essential for direct adhesion between rubber compounds and nickel plated metals.4) In this study, many trial products were made. Some of them will be produced industrially by small company in lwate prefecture. Less

本文提出的金属与橡胶直接粘接技术，在理论上和实践上都具有一定的应用价值。本研究的目的是阐明镀镍层表面组成和硫化体系对粘合的影响，并对比硫化过程中橡胶与金属之间的直接粘合机理。1）镀镍金属在空气暴露下增加了氧化层的厚度，超过20* 厚，在常规硫化条件下不与橡胶化合物粘合。在这些情况下，电镀表面覆盖有氢氧化镍，其不产生橡胶分子与镍表面或镍反应产物之间的界面键合，并改变为非粘附表面。2）常规化合物如NR、CR、NBR、HS-NBR、EPDM、FR、AR通过在固化期间添加三嗪硫醇而粘附到镀镍金属。良好的附着力和性能 ...更多信息通过控制三嗪硫醇与关键助剂的配比，得到了较好的硫化胶。在过氧化物硫化体系中，三嗪硫醇的存在获得了良好的平衡。3）硫化过程中橡胶化合物与镀镍金属之间的直接粘合解释如下。在这种粘合中，当橡胶化合物和镀镍金属接触时，两者之间形成化学势差。化学势的差异导致镍离子与三嗪硫醇或梯度反应;镍离子从镀镍层扩散。反应导致硫化胶与镀镍层之间形成界面结合和增强层，通过界面分析确定结合和增强层。这两种形成对于橡胶化合物和镀镍金属之间的直接粘合是必不可少的。4）在本研究中，制备了许多试制产品。其中一些将由岩手县的小公司进行工业化生产。少
