摘要:
使用优选的乳化剂对增塑剂环烷油(NAP)进行乳化,制得均一稳定的NAP乳化液,采用湿法混炼技术,使用所得的NAP乳化液与天然胶乳和白炭黑(SiO2)浆液制备了NAP增塑的天然橡胶(NR)/SiO2(NAP/NR/SiO2)复合材料,研究了NAP添加量对NAP/NR/SiO2复合材料门尼黏度、物理机械性能、动态力学性能、SiO2分散性、耐热空气老化性能和屈挠龟裂性能的影响。结果表明,NAP/NR/SiO2复合材料的门尼黏度较NR/SiO2复合材料显著降低,Payne效应明显减弱,而动态力学性能和加工性能则明显提升;NAP添加量为10份(质量)时,NAP/NR/SiO2复合材料的综合性能达到最佳,其拉伸强度与NR/SiO2复合材料相比略微下降,而扯断伸长率则有不同程度的上升;加入NAP后,NR/SiO2复合材料的耐热空气老化性能和屈挠龟裂性能得到了改善。
Abstract:
The preferred emulsifier was used to emulsify the plasticizer naphthenic oil (NAP), and uniform and stable NAP emulsion was prepared. The NAP-plasticized natural rubber (NR)/silica (SiO2) (NAP/NR/SiO2) composite was prepared using the resulting NAP emulsion, NR latex and SiO2 slurry by wet mixing process, and the effects of NAP addition amount on Mooney viscosity, physical and mechanical properties, dynamic mechanical properties, dispersion of SiO2, thermal air aging resistance and flexural cracking property of NAP/NR/SiO2 composites were studied. The results showed that Mooney viscosity of NAP/NR/SiO2 composite was significantly lower than that of NR/SiO2 composite, Payne effect was significantly weakened, and dynamic mechanical properties and proces-sability improved significantly. When NAP addition amount was 10 phr (mass), NAP/NR/SiO2 composite had the best comprehensive performance, and tensile strength of NAP/NR/SiO2 composite decreased slightly, whereas elongation at break increased to varying degrees when compared with those of NR/SiO2 composite. Thermal air aging resistance and flexural cracking property of NR/SiO2 composite improved after the addition of NAP.
