The preparation of nanometer cellulose (S-BNC) by sulfuric acid hydrolysis had the disadvantages of high pollution

high risk and high treatment cost

but alkaline hydrolysis was environmentally friendly with low energy and low cost. Nano-cellulose (2-BNC) was prepared from bagasse by alkaline hydrolysis and was used to reinforce styrene butadiene rubber (SBR). The effects of 2-BNC on the performance of SBR were investigated

and further compared with SBR/silica and SBR/S-BNC composites at the same amout of fillers. The results show that the interface between 2-BNC and SBR matrix is better than that of SBR/silica system. Under the same packing fraction

DMA test results show that the addition of 2-BNC can improve the cold resistance of SBR vulcanizate. Compared to the SBR and SBR/silica systems

the SBR/2-BNC system glass transition temperature (Tg) of move towards low temperature. At high elastic state

the modulus of SBR/2-BNC system are higher than that of SBR/silica system; SBR/BNC composites exhibited better mechanical properties and abrasion resistance compared with SBR/silica composites. At the same amount of filler

the tensile strength and elongation at break of SBR/2-BNC vulcanizate are equal to that of SBR/silica vulcanizate. The stress and tear strength of SBR/2-BNC vulcanizate are higher than that of SBR/silica vulcanizate; Scanning electron microscopy (SEM) analysis show that the 2-BNC and SBR matrix has good interfacial compatibility. Dispersity of 2-BNC is better than that of silica in the matrix. The reinforcing effect of 2-BNC on SBR has no significant difference compared with that of S-BNC.
