橡胶与金属粘合中的底涂粘合技术及其测试

橡胶与金属的粘接技术在现代社会中发挥着重要的作用。其中，底涂胶粘剂起到了连接金属和橡胶的桥梁作用。该文从理论和实践二个方面探讨了底涂胶粘剂的作用机理及其性能要求。通过耐缩径产品举例说明，如何将实际的性能要求转化为底涂胶粘剂的开发实践。除底涂材料外，金属的表面处理也会大大影响粘合体系的耐腐蚀性。文中考察了不同表面处理方式对粘合体系耐盐雾性的影响。同时，还研究了底涂胶粘刺作为单涂或者单涂作为底涂胶粘剂的可能性。

Rubber to Metal Bonding - Technologies to reach increasing demands on Primers

The rubber to metal bonding technology is one of the essential key technologies today and in future.In between,the function of the primer is to provide "a bridge" between the widely different polarities and surface energies of the metal or plastic substrates,the covercement,and the rubber.In this article,the bonding mechanism and properties requirements were theoretically discussed.On the example of rubber to metal bonded concentric bushes which must be reduced in diameter post vulcanization we describe how these requirements were transformed practically.Besides primer,the anti-corrosion property for the whole system was greatly affected by different substrate surface treatment.The influence of salt spray climate test properties was investigated by different metal surface treatment.In addition,the possibility of one coat using primer or primer using one coat was studied.
