Abstract:
      Organic clay/natural latex（NRLCNs） nanocomposites（NRLCNs） were prepared by emulsion intercalation method.The effects of organic clay dosage on the tensile properties of NRLCNs and the changes in the tensile induced crystallization behavior of NRLCNS under different tensile modes，tensile ratios and tensile cycles were investigated.The results showed that when organic clay dosage was 4 phr，the tensile strength of NRLCNs was largest，at 24.6 MPa，which was 95% larger than the tensile strength of pure NRL compound of 12.6 MPa.The addition of organic clay contributed to the faster formation of tensile-induced crystallization of NRLCNs.In a certain range，the critical mutagenic point of tensile-induced crystallization of NRLCNs was advanced with the increase of organic clay dosage.After pretreatment with different tensile ratios and tensile cycles，the critical mutagenic point of tensile induced crystallization of NRLCNs exhibited varying degrees of hysteresis.The tensile strength of NRLCNs increased with the increase of tensile cycles of multi-axial tensile pretreatment，and after the same pretreatment，the uniaxial tensile strength of NRLCNs was larger than the multi-axial tensile strength under the same strain.
