Abstract:
      The non-rubber components（NRCs） in natural rubber（NR） had a significant impact on its structure and properties，it helped to transform the NR molecular chains from linear to a network structure in the process of constructing molecular structure of NR. However，in the preparation of conventional smoked sheet rubber and standard rubber，the acid coagulation process and processing methods such as shear and high-temperature drying resulted in significant loss of NRCs. The NR prepared by thin film drying method employed in this study largely avoided this issue.Full component NR compound prepared by this method exhibited excellent mechanical properties. A comparison of the properties between NR that removal each NRCs revealed the following：removal of phospholipids led to a 26.92% decrease in Mooney viscosity of NR compound，a 24.91% shortening in vulcanization induction period，and an improvement in aging resistance.Removal of proteins led to a 1.72% decrease in Mooney viscosity of NR compound，a 50% shortening in vulcanization induction period，and a certain degree of improvement in aging resistance.
