| Abstract: |
| The influence of waste rubber powder and sawdust on the physical properties of waste paper pulp was investigated.The results showed that，the physical properties of waste rubber powder/waste paper pulp，sawdust/waste paper pulp and waste rubber powder/sawdust/waste paper pulp composite were enhanced，and the physical properties of waste rubber powder/waste paper pulp composite were superior to those of waste rubber powder/sawdust/waste paper pulp composite.So the effect of waste rubber powder on the modification of waste paper pulp was better.The optimum formulation of waste rubber powder/waste paper pulp composite was as follows：waste paper pulp 100（calculated on dry material），waste rubber powder 8，antioxidant D 0.2，sulphur 0.2，accelerator M 0.2.The optimum cure condition was 150 ℃/10 MPa×30 min.Under this condition，the surface of waste rubber powder/waste paper pulp composite was smooth，the structure was compact and uniform，and the arrangement was even，and the compatibility between waste rubber powder and waste paper pulp was good. |
