摘 要
以高弹性为特征的橡胶材料在国民经济各部门有着广泛的应用。但是，橡胶的固有力学性能决定它的弹性模量较小，例如，一般软质橡胶的杨氏模量约为1Mpa,而金属材料高达104~105MPa。因此，有不少场合，要求橡胶与金属、塑料等刚性材料相互复合，以期能同时利用橡胶的弹性以及后者的刚性，使橡胶制品获得更高的强度和耐久性。不言而喻，在这类复合材料的制作上，粘合是最重要的工艺环节之一。
如何解决橡胶与金属的粘接问题，现已成为研究的热门。在硫化过程中实现橡胶与其他材料粘合是目前橡胶制品生产中采用的基本方式。经过适当表面处理的金属，有时即可直接与橡胶在加热加压的硫化过程中实现粘合，但是，这有一定的局限性。因此，使用适当的胶粘剂系统来实现橡胶与金属粘合被认为是当前最有效的方法。
本文研究了在室温下，通过改变橡胶配方，对多种特种硫化橡胶与金属进行了粘合。并对试样进行了拉伸强度、剪切强度、剥离强度等多项测试。通过对实验结果的分析，探讨了胶粘剂的粘合机理以及影响粘接强度的各种因素。

Abstract
Rubber materials have high elasticity, there is extensive application in all national economy departments. However, the inherent mechanics performance of the rubber determines its elastic modulus is relatively small, for example, the general soft rubber’s modulus is about 1Mpa, and the metal material is up to 104~105MPa. So, there are many occasions , require the rubber bonds with rigidity materials such as metal , plastics and etc, expect to utilize elasticity of the rubber and the latter's rigidity at the same time , make the rubber products obtain higher intensity and durability. Self-evident, in the manufacture of this kind of composite, bonding is one of the most important craft.
And how to solve rubber to metal bonding has already become emphasis of the research now. At present, the method of rubber bonding with other materials is basic way that we adopt in the rubber products manufacture during the course of sulphurating. Through proper surface treatment, the metal can direct bonging with rubber in the course of heating and pressurizing vulcanization sometimes, however, to certain extent it has limitation. So, use the proper adhesive system to make the rubber and metal bonding is considered to be the most effective method at present.
This text has been studied under the room temperature, through changing the rubber, we have bonded many kinds of vulcanized rubber to
