| Abstract: | POE-g-MAH/OMMT toughening particles were prepared by ball grinding method and were used to modify the toughness of PA6.The results showed that the size of POE-g-MAH/OMMT particles prepared by ball grinding method was uniform.A small amount of POE-g-MAH get into the layers of OMMT,which increased the pitch of OMMT layers.The dispersion of POE-g-MAH/OMMT particles in PA6 matrix was better,but a slight agglomeration of particles occurred.With content of the POE-g-MAH/OMMT particles increasing,the notched impact strength of PA6/(POE-g-MAH/OMMT) blend increased.When the mass fraction of toughening particle exceed 15%,the mechanical properties of PA6/(POE-g-MAH/OMMT) blend were higher than PA6/POE-g-MAH blend.When the mass fraction of toughening particle was 15% and mass ratio of POE-g-MAH/OMMT was 80/20,the notched impact strength and tensile strength of PA6/(POE-g-MAH/OMMT) blend were highest. |
