| Abstract: |
| The contents of inorganic elements in natural rubber（NR）and isoprene rubber（IR）were
determined by ICP-OES. Phosphorus element was selected as the identification element of NR，and
neodymium and titanium elements were used for IR. The contents of phosphorus，neodymium and titanium
elements in raw rubber such as emulsion styrene-butadiene rubber，solution styrene-butadiene rubber and
butadiene rubber were tested. The identification methods of raw rubber materials in tire vulcanizate using
phosphorus element content as the main detection index，and neodymium and titanium contents as supplement
were discussed. |
