Abstract:
      Modified rod-shaped straw nanocellulose（MSNC，modified SNC） was prepared by grafting of coupling agent Si69，and the effect of MSNC on the properties of carbon black（CB） reinforced natural rubber（NR） was studied.The results showed that，MSNC had good compatibility with rubber matrix. Compared with CB/SNC/NR composite，CB/MSNC/NR composites had a greater crosslink density，better wet skid resistance and lower rolling resistance，stronger cross-linking network，more restricted rubber molecules and better thermal stability.CB/MSNC/NR composite with a ratio of 35/10/100 had the best physical properties.
