摘要

用大分子吸附（OT吸附及CTAB吸附）和低温氮吸附测定的试验炭黑和普通高结构中超耐磨炉黑的比表面积和表面粗糙度表明

试验炭黑的表面粗糙度比较大

其表面11—15A细孔内的表面积比普通产品高10m~2/g。通过拉伸电阻率的测定发现

在天然胶和顺丁胶中含试验炭黑的硫化胶电阻率最低点处的伸长率比较低

炭黑与橡胶之间的结合比较弱。这可以用炭黑表面细孔诱导硫化胶内“空洞”产生和扩展以及炭黑聚集的观点来解释

从而认为炭黑表面粗糙度对橡胶的补强作用有直接影响。这可能是含试验炭黑的轮胎胎面（顺丁胶与天然胶之比为70/30）在实际里程试验中耐磨性大大低于普通高结构中超耐磨炭黑的原因。试验中观察到

丁苯胶中炭黑粗糙度对拉伸电阻率的影响不同于天然胶和顺丁胶

这是丁苯胶松弛特性不同造成的。

Abstract

Nitrogen adsorption and macromolecular adsorption show that there are more micropores on the surface of the experimental carbon black. We have studied the effect of micropores of black on reinforcement in NR (Natural Rubber)

BR (Butadiene Rubber) and SBR (Styrene-Butadiene Rubber) by measuring tensile resistance of black filled Vulcanizates. It has been found that under same conditions the bond strength between NR or BR and the experimental black was weaker. This phenomenon is probably due to poreinduced cavity. The effect of roughness of black on tensile resistance of black filled SBR vulcanizate differs from that of NR and BR vulcanizates

because it has different relaxation characteristics.
