摘　　要：Vulcanization is an essential process to obtain high-performance rubber products.Diphenylguanidine(DPG)is often used as the secondary accelerator in the vulcanization process of natural rubber(NR)latex.However,DPG would make NR latex emulsion exhibit gelation,resulting in the negative vulcanization efficiency.In addition,exposure to DPG might lead to some physiological diseases during the production process of DPG doped NR latex.Hydroxypropyl-β-cyclodextrin(HP-β-CD)with the hydrophobic interior and hydrophilic exterior has the advantages of good water solubility,high bioavailability,reliable stability,and low toxicity.In this study,the inclusion complex of diphenylguanidine-hydroxypropyl-β-cyclodextrin(DPG-HP-β-CD)is prepared by bali milling with a host-guest molar ratio of 1:1,which has also been applied to the foaming process of NR latex.The mechanical properties of DPG-HP-β-CD inclusion complex/natural rubber latex foam(DPG-HP-β-CD/NRLF)have been significantly improved,including the tensile strength,elongation at break,hardness,compression set,resilience,and antiaging performance.Further,the usage of DPG has been reduced,leading to the reduction of toxicity and environmental hazards.
