| Abstract: | A new kind of surfactant ADDP was used as surface modifier to modify the nano CaCO 3. The influence of temperature, time, the concentration of ADDP and pH etc. on the property of nano CaCO 3 has been investigated. The average dispersed diameter of CaCO 3, the viscosity of CaCO 3/DOP system and the oil absorption rate have been measured. The modified nano CaCO 3 had been used to fill into soft PVC. The processing and mechanical properties have been studied. |
