Study on the Surface Modification of Illite in West Sichuan by Using Titanate

By taking the illite in west Sichuan as the research object and titanate JN-114 as the modifier,this thesis contrastively studied on the differences of viscosity,mechanical properties of unmodified illite/organic and modified illite/organic composite system and studied the surface bonding state of titanate coupling agent and illite on the basis of basic properties of the illite.The experimental results showed that the optimum dosage range of titanate was 0.6%~1.2% under laboratory conditions when the illite was modified.According to the result of infrared analysis,the titanate coupling agent possibly enwraps the surface of the illite powder in the main mode of physical adsorption and effectively modifies the surface characteristics of illite.Mechanical properties of the modified illite/PVC composite materials are significantly improved compared with the unmodified illite/PVC.
