内容摘要
本论文阐述了橡胶与金属粘合在许多工业领域有着广泛的应用，如汽车制造、军工方面、道路桥梁以及机械制造等。采用橡胶与金属材料复合可以获得更好的强度和耐久性,同时获得减振、耐磨等功能。
橡胶与金属粘合大都采用硫化粘合方式,但当硫化条件下基材不稳定或硫化粘合工艺不易实现时则采用冷粘方式。由于硫化橡胶表面的极性较弱、活性较低,并且存在脱模剂和喷霜物,因此要想把它粘合到强极性的金属表面上就必须对其进行清理和化学处理。传统的化学处理方法是酸处理法,但该法存在许多缺点,例如使被处理的硫化橡胶表面老化产生微裂纹，导致橡胶物理机械性能下降，并且处理工艺复杂、环境污染严重等。
本文研究了在室温下，通过改变橡胶配方和对硫化胶进行不同的处理来改善橡胶的性能，采用方法有：臭氧氧化法、紫外线照射及紫外线照射和臭氧氧化共同作用对多种硫化橡胶进行了粘合。并对试样进行了拉伸强度、剪切强度、断裂伸长率等测试。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。
最后通过不同处理方法结论的对比，来确定要获得更好橡胶与金属的粘结效果所需要的橡胶品种及处理方式。

Abstract
In this paper , it expounds that the rubber to metal bonding has an extensive application in many industrial fields. For instance car making, war industry, road, bridge and machine-building etc. Adopt rubber to metal bonding can obtain kind intensity and durability, at the same time, reduced the function of shake , wear-resisting etc.
The rubber to metal bonding mostly adopt sulphurate bonding. But if under sulphurating condition the bonding layer is unstable, or suppurating craft is difficult to come true，we adopt cold bonding. Because the polarity on the vulcanized rubber surface is weaker, the activation is relatively low, and exist mold separating agent and blooming. It must go on clear up and chemical disposal if you want to bond the vulcanized rubber to strong polarity metal. The traditional chemical disposal method is acid treatment ,but this method have a lot of shortcoming, for example, makes the vulcanized rubber surface aging and produces a lot 无忧论文 【http://www.uklunwen.com】of cracks, reduces the vulcanized rubber physical performance, and disposal craft complicated, and seriously polluted environment etc.
This paper has been studied at ambient workshop temperarure ,through changing the rubber and adhesive prescription and different treatments to vulcanized rubber , we have bonded many kinds of rubber to metal. We adopt many treatments To improve zhe properties of ruber ,such as the oxidization of ozone , zhe irraddiation of ultraviolet ray , and the joint effect of them. we may carry on multinomial testing to the sample such as tensile strength, shearing strength, bonded strength, and low temperature elongation at break and so on. Through an analysis of experimental result ,we have discussed the bonding mechanism of the adhesive, and the influencing factors of bonding intensity.
By comparing three kinds of diffent treatments from zhe results of experiment , we may find a better formula of rubber and a better treatment to get a better effect of the rubber to metal bonding.
