| Abstract: |
| The Chloroprene Rubber / organic clay nanocomposites (CRCNs) were prepared by melt blending method. The structure of CRCNs under different strain conditions was observed by polarizing microscope. This paper mainly studies the influence of organic clay on strain-induced crystallization of chloroprene rubber. And the microscopic phase structure of CRCNs was characterized by XRD and SEM. The result show that when the content of organic clay is 5 phr, the mechanical properties of CRCNs are optimal,the stress of CRCNs increases with the strain increase. The stress of CRCNs increases rapidly when the strain reaches a certain value, and the strain-induced crystallization of CRCNs occurred. With the clay content increasing, the tensile crystallization behavior of CRCNs is produced under high strain conditions. The reason is that the intercalation structure of organic clay and rubber molecules decreases gradually and the ability of induced crystallization weakens. |
