SYNTHESIS OF NANOSIZED CALCIUM CARBONATE AND ITS INFLUENCE ON MECHANICAL PROPERTIES OF NR/EPDM BLENDS
Abstract
The polymer mediated technique is a versatile technique for the preparation of nano particles In the present study we have prepared the nano particles of calcium carbonate by polymer mediated growth method and were characterized using different techniques (Mishra S, Patil U D and Shimpi N G, 2009). Further, these particles were incorporated into NR/EPDM blends by two roller mill mixing technique. Various mechanical properties of the composites were characterized by standard methods. Nano particles of calcium carbonate in the range of 5-10 nm were prepared and characterized by XRD and TEM. The tensile testing results showed that the presence of nanoCaCO3 enhances the mechanical properties of NR/EPDM blends.
