Abstract:
      The natural rubber（NR） composites of four rubber tree strains（72059，PR107，73397 and RRIM600） filled with silica or halloysite were prepared，and their properties were studied. The results showed that the vulcanization properties of NR composites filled with silica or halloysite were less affected by the rubber tree strain. The RRIM600 composites filled with silica or halloysite exhibited the largest swelling equilibrium crosslink density，the best physical properties and the smallest loss factor in the range of 50～70 ℃，which indicated that the hysteresis loss of RRIM600 composites was the smallest and RRIM600 met the requirements of low rolling resistance tires，and the corresponding properties of 72059 composites were poor，but the thermal stability of 72059 composites filled with silica was the best. The difference among the thermal stability of NR composites of various rubber tree strains filled with halloysite was not obvious. The comprehensive properties of PR107 composites and 73397 composites were in the middle.
