內(nèi)容摘要

本論文闡述了橡膠與金屬粘合在許多工業(yè)領(lǐng)域有著廣泛的應(yīng)用，如汽車制造、軍工方面、道路橋梁以及機(jī)械制造等。采用橡膠與金屬材料復(fù)合可以獲得更好的強(qiáng)度和耐久性,同時(shí)獲得減振、耐磨等功能。
橡膠與金屬粘合大都采用硫化粘合方式,但當(dāng)硫化條件下基材不穩(wěn)定或硫化粘合工藝不易實(shí)現(xiàn)時(shí)則采用冷粘方式。由于硫化橡膠表面的極性較弱、活性較低,并且存在脫模劑和噴霜物,因此要想把它粘合到強(qiáng)極性的金屬表面上就必須對(duì)其進(jìn)行清理和化學(xué)處理。傳統(tǒng)的化學(xué)處理方法是酸處理法,但該法存在許多缺點(diǎn),例如使被處理的硫化橡膠表面老化產(chǎn)生微裂紋，導(dǎo)致橡膠物理機(jī)械性能下降，并且處理工藝復(fù)雜、環(huán)境污染嚴(yán)重等。
本文研究了在室溫下，通過改變橡膠配方和對(duì)硫化膠進(jìn)行不同的處理來(lái)改善橡膠的性能，采用方法有：臭氧氧化法、紫外線照射及紫外線照射和臭氧氧化共同作用對(duì)多種硫化橡膠進(jìn)行了粘合。并對(duì)試樣進(jìn)行了拉伸強(qiáng)度、剪切強(qiáng)度、斷裂伸長(zhǎng)率等測(cè)試。通過對(duì)實(shí)驗(yàn)結(jié)果的分析，探討了膠粘劑的粘合機(jī)理以及影響粘接強(qiáng)度的各種因素。
最后通過不同處理方法結(jié)論的對(duì)比，來(lái)確定要獲得更好橡膠與金屬的粘結(jié)效果所需要的橡膠品種及處理方式。

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 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.
Key words: rubber and metal; bonding; vulcanized rubber
