A Study on the Reinforcing Effects of Inorganic Filler Contained NR Vulcanizates with Temperature and Loading Variation.

무기충전제(無機充塡劑)를 변량배합(變量配合)한 천연(天然)고무 가황체(加黃體)의 온도변화(溫度變化)에 따른 보강성효과(補强性效果)의 연구(硏究)

The purpose of this study is to examine the effect of rubber-filler attachments on inorganic filler contained NR vulcanizatic. The results of this study showed as follows. The reinforcing properties and damping values of the vulcanizates in the elastic region showed strong relation with the filler characteristics and temperture. The vulcanizates filled with nature-activated inorganic filler like silica had higer elastic modulus and damping values than the vulcanizates of nature-nonactivated inorganic filter. The reinforcing effects of differential filler loadings on NR raised the effects with temperature rise, but the damping values varied with the filler characteristics and temperature variations.
