| Abstract: |
| A modified kaolinite/NR composite was prepared by coacervation-coprecipitation of concentrated NR latex with modified kaolinite and the influence of the preparation conditions on the mechanical properties of vulcanizate was investigated.Moreover，the tensile sectional morphology of vulcanizate was analyzed by SEM.The results showed that the modified kaolinite/NR composite possesed excellent physical properties and the modified kaolinite particles adhered tightly to NR matrix during tensile；and a modified kaolinite/NR composite with the optimal physical properties was obtained when the content of the potassium lactate solution modifier was 0.05，the kaolinite was modified at 80 ℃ and 40 phr modified kaolinite was used in the composite. |
