| Abstract: |
| A new approach to prepare high performance water-swelling rubber was introduced.The water absorption property and physical properties of water-swelling rubber were improved by adding nano-crystalline cellulose（NCC） and nano-silica sol（NSS） in the preparation of water-swelling rubber with sodium acrylate grafted natural rubber latex.The results showed that the comprehensive properties of water-swelling rubber were better when 60 phr sodium acrylate，0.75 phr NCC and 3 phr NSS were used，and the degree of swelling was 10.013，equilibrium swelling time was 11 h，water absorption ratio for the second time reached 97.3%，and tensile strength was 12.25 MPa. |
