本文研究了硫化橡胶与金属的结合。以前有报道称，发现双（三乙基氧基硅基）乙烷和乙烯基三乙基氧基硅烷可用于将过氧化物固化橡胶化合物与金属结合。这些硅烷被发现不能与硫化橡胶化合物一起工作。在这种情况下，发现双（三甲氧基硅丙基）胺和双（三乙氧基硅丙基）四硫化物的混合物起作用，并提出了将黄铜、钢和电镀锌钢粘合到有或没有钴添加剂的典型轮胎帘子线脱脂化合物上的实验结果。这种新的硅烷处理被发现与黄铜对含钴橡胶化合物的粘附一样有效或更好。通过直流腐蚀和极化电阻测试也证明了硅烷具有优异的防腐性能。本文报道的硅烷工艺在所有金属衬底上的表现几乎相似。本文研究了金属基板上硅烷膜的结构，提出了橡胶化合物与硅烷包覆金属的粘附机理模型。
This paper deals with the bonding of sulfur-vulcanized rubber compounds to metals. It had previously been reported that bis-(triethoxysilyl)ethane and vinyltriethoxysilane were found to work for bonding peroxide-cured rubber compounds to metals. These silanes were found not to work with sulfur-cured rubber compounds. In this case, a mixture of bis-(trimethoxysilylpropyl)amine and bis-(triethoxysilylpropyl) tetrasulfide was found to work and results are presented of experiments in which brass, steel, and electrogalvanized steel were bonded to a typical tire cord skim compound with and without a cobalt additive. This new silane treatment was found to be as effective as or better than brass adhesion to cobalt-containing rubber compounds. The superior corrosion protection offered by the silanes was also demonstrated using DC corrosion and polarization resistance measurements. The silane process reported in this paper behaves almost similarly with all metal substrates. In this paper, the structure of the silane film on a metal substrate is studied and a model is proposed for a possible mechanism of the adhesion of rubber compounds with silane-coated metals.
