[求助] 求助炭黑方面的几句文献翻译(中译英)

研究了炭黑类型及用量对丁基橡胶(IIR)动态力学性能的影响。
研究结果表明,随着炭黑粒径的增大,tan δ值所对应的温度
变化不大,都在-1.5℃左右,但是tan δ max   值呈明显上升
的趋势,且玻璃化转变区域逐渐变宽,储能模量E’降低。炭
黑粒径越大,在橡胶基体中所形成的结合胶越少,交联密度
越低。当橡胶受到交变应力作用时,橡胶大分子链易在炭黑
表面滑动,橡胶分子链与炭黑表面间的摩擦造成的能量损耗
增加,硫化胶的损耗因子峰值呈增高趋势;随着炭黑N990用
量的增加,IIR硫化胶的玻璃化转变区域逐渐变窄,tan δ峰值
逐渐变小,而Tg略有升高。

Studies  of the influence of dynamic mechanical properties of butyl rubber by the type and amount of carbon black (IIR)  showed that with the increase of the size of the carbon black particle  , little  tan δ changed at around -1.5 ℃corresponding to the temperature, but the tan δ max values ​​were significantly increased. With glass transition region gradually widened, the   storage modulus E 'decreased. The larger Charcoal Black  diameter, the less jointed rubber   to form in the rubber matrix and the lower crosslinking density. When the rubber subjected to alternating stress , rubber macromolecular chains are likely  slide over the  surface of the carbon black . The  friction between the  rubber molecular chain and the surface of   carbon black caused higher  energy  loss  and the vulcanized rubber loss factor peak   rised . With the  increasing use of carbon black N990, the glass transition region of the vulcanized rubber IIR is gradually narrowed , tan δ peak became smaller and the Tg increased slightly.
