IMPROVED NATURAL RUBBER COMPOSITIONS

摘要

There is herein described improved natural rubber compositions for use in engineered rubber products for use in civil and mechanical engineering applications having nanocarbon and carbon black as reinforcing agents wherein the nanocarbon is uniformly pre-dispersed within the rubber component. In particular there is described rubber compositions comprising a mixture of natural rubber, nanocarbon and carbon black wherein the relative amount in parts per hundred rubber (pphr) of nanocarbon to carbon black is in the range of about 1:40 to about 1:2 and the relative amount in parts per hundred rubber (pphr) of nanocarbon to natural rubber is in the range of about 1:100 to about 10:100 and wherein the nanocarbon component is pre-dispersed within the natural rubber component.
