摘要
采用乳液共凝法制备纳米Fe3O4/天然橡胶(NR)复合材料,所用纳米Fe3O4是用化学共沉淀法制备的纳米Fe3O4乳液。研究了纳米Fe3O4用量对纳米Fe3O4/NR复合材料的力学性能、热稳定性、加工性能的影响。结果表明:纳米Fe3O4的用量对纳米Fe3O4/NR复合材料的性能有较大的影响。在NR中加入纳米Fe3O4,混炼胶的G′较高,tanδ较小,提高了复合材料的力学性能和热稳定性。当纳米Fe3O4的质量分数为15%时,纳米Fe3O4/NR复合材料的综合性能较好。
To adopt emulsion coagulating prepares nano-Fe3O4/NR compound,what Fe3O4 is to use chemistry to precipitate.The dosages of nano-Fe3O4 have the effect on mechanics function,thermal stability and processing function of nano-Fe3O4/NR compound.Results show that the dosages of nano-Fe3O4 have apparent effect on the function of nano-Fe3O4/NR compound.Adding nano-Fe3O4 in the rubber,rubber compound ＇s G′ is higher,tan δ less,and the mechanics function and the thermal stability of nano-Fe3O4/NR compound have been raised.When nano-Fe3O4 dosages are 15%,the function of nano-Fe3O4/NR compound is fairly good.
