【Abstract】 Montmorillonite was expanded with octadecylammonium before intercalated with epoxy resin,then acrylic acid was added to form epoxy acrylate resin/montmorillonite prepolymer which was UV cured to obtain a coating film. The film was characterized by XRD diffraction and impact test as well as shrinking rate measurement. The results shows that the impact strength of acrylate resin/montmorillonite composites is the highest when montmorillonite content is 1～2%. The higher is the content of montmorillonite, the lower becomes the shrin-king rate of the result composites.更多还原
