金属与橡胶粘合强度测试.docVIP

摘 要 橡胶与金属是两种不同的材料，它们的化学结构和机械性能有着很大的差别。借助橡胶与金属的粘合，可以使两种材料结合成人们所需要的有着不同构型和不同特性的复合体。 本研究工作是以环氧树脂粘合剂作为结构胶进行金属与丁基橡胶、三元乙丙橡胶、丁苯橡胶、顺丁橡胶非极性硫化橡胶的粘接，并测试其剪切强度。另外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使用橡胶表面化学处理法。 通过实验对各种非极性橡胶进行了等离子体、臭氧、紫外线、臭氧+紫外线等处理，并且讨论了处理方法对非极性硫化橡胶与金属的粘接强度的影响。最后对不同处理方法下的丁苯橡胶和乙丙橡胶做了扫描电镜分析，讨论了它们不同的表面形态。 关键词：硫化橡胶；粘和；金属；等离子；处理方法。 ABSTRACT The rubber and metal are two kinds of different materials, their chemistry structure and the machine function have the very big difference. Ask for help the adhesion of the rubber and metal, can make two kinds of materials combine the people need of have compound body of the different configuration and different characteristic. This research work is the structure gum to carry on the metal and NR, BR, IIR, EPDM, SBR, the cis-1,4-polybutadiene rubber non- polarity Vulcanization to glue the adjoin with the adhesive of epoxy resin, and test its shear strength. The weaker is because of the polarity of the surface of Vulcanization moreover, the activity is lower, and exist the releasing agent and spray frost thing, so to want to make the metal that its adhesion arrives the strong polarity use the rubber surface chemistry treating method superficial must. Passed the experiment to carried on etc. to various non- polarity rubber ion body, ozone, ultraviolet ray, ozone and ultraviolet ray etc. treating, and discussed the treating method to glue the influence of connect the strength to the non- polarity Vulcanization and metal. Finally to the dissimilarity handle under method of different from SBR and EPDM rubber did the scanning electron microscopy, SEM, discuss them surface appearance of styrene butadiene rubber, SBR.
