Abstract

This research was aimed at verifying the effect of carboxy-containing peroxy oligomer (CPO) addition on the possibility of rubber crosslinking and a subsequent adhesion of the modified rubber to silver wires. Three commonly industrially used rubbers were selected for the study: styrene-butadiene rubber (SBR), acrylonitrile-butadiene rubber (NBR) and carboxylated acrylonitrile-butadiene rubber (XNBR), together with carboxy-containing peroxy oligomer (CPO). An improvement in the adhesion of rubbers to silver wires was observed when applying the oligomeric peroxide with functional groups, with no deterioration of mechanical properties of the vulcanizates. Crosslinking synergy between dicumyl peroxide (DCP) and the modifier could hardly be observed. Nevertheless, the studies demonstrated, that to a small extent, even the CPO itself can crosslink NBR and especially XNBR, resulting in a material of notable elasticity and adhesion to silver wires.

摘要

本研究旨在验证添加含羧基过氧低聚物（CPO）对橡胶交联可能性以及改性橡胶与银线后续附着力的影响。选择了三种工业上常用的橡胶进行研究：丁苯橡胶（SBR）、丁腈橡胶（NBR）和羧基丁腈橡胶（XNBR），以及含羧基过氧低聚物（CPO）。当使用具有官能团的低聚过氧化物时，观察到橡胶与银线的附着力有所提高，且硫化胶的机械性能没有恶化。几乎未观察到过氧化二异丙苯（DCP）与改性剂之间的交联协同作用。然而，研究表明，即使CPO本身也能在一定程度上使NBR尤其是XNBR交联，从而得到具有显著弹性且与银线有附着力的材料。
