摘要：

Through constructing deproteinized natural rubber (DPNR) and transesterificated-deproteinized natural rubber (TEDPNR) models as objectives, the effect of phospholipids on unvulcanized natural rubber network was studied. Uniaxial tension of DPNR, TEDPNR and NaOH-TEDPNR was applied to measure mechanical performance with the results that phospholipids could form long chain branching. Furthermore, the resulting intense entanglement could form effective network under rapid stretching. It is found that phospholipids can form strong entanglement network by studying the relaxation behavior of models at room temperature, which can restrict the relaxation of construction units. Dynamic creep and strain softening tests suggest that long chain branching network formed by phospholipids and the hydrogen bonding network participated by phospholipids play an important role in keeping the elastic deformation at large variation and resisting the destruction of network structure under dynamic loading. © 2016, Chengdu University of Science and Technology.
