Summary: | The present invention relates to a process for modifying the surface polarity of elastomeric rubber substrates to facilitate their cold bonding to other rubber substrates or non-elastomeric substrates of a different material, preferably metal, by chlorinating the rubber substrate surface by treatment with a chloride-containing composition and a peroxymonosulfate-containing composition. Further aspects relate to the thus obtained surface-modified rubber substrates, processes of bonding them to other substrates by use of an adhesives as well as the thus obtained bonded substrates.
本发明涉及一种通过用含氯化物的组合物和含过一硫酸盐的组合物处理使橡胶基材表面氯化来使弹性橡胶基材的表面极性改性以促进它们对其他橡胶基材或不同材料的非弹性基材的冷粘合的方法。其他方面涉及由此获得的表面改性橡胶基材、通过使用粘合剂将它们粘合到其他基材的方法以及由此获得的粘合基材。 |
