Method for preparing a nanocomposite rigid material

摘要

Preparing a material constituted by a PVC matrix reinforced by clay, comprises: preparing a modified clay by mixing natural clay with a non-volatile solvating compound, the mixing is implemented by applying following mechanical constraints (speed in m/s) such as compression (0.01-0.5), shearing (0.05-5), friction (0.05- 5) and attrition (2-4); and incorporating the modified clay in the PVC by mixing in molten state under a compression speed of 0.1-5 ms -> 1> and shearing rate of 0.05-5 ms -> 1>.
