摘要
采用具有转子密封圈油密封系统的GK-5E型密炼机,研究不同填料体系胶料在混炼过程中的质量变化、密度及拉伸性能。结果表明:用于密封的机械油会在混炼过程中部分进入到混炼胶中;混炼温度和混炼时间对硫化胶的拉伸性能影响不大;胶料配方中白炭黑用量过大会影响混炼时间,进而对硫化胶的拉伸性能产生影响。
In this study,the mass change,density and tensile properties of the compound with different filler systems in the mixing process were studied by using a GK-5 E mixer equipped with oil seals for the rotors.The results showed that the compound might be contaminated by the sealing oil during the mixing process.The mixing temperature and mixing time had little effect on the tensile properties of the vulcanizates.If the silica dosage in the compound formula was excessively high,the mixing time would be prolonged and the tensile properties of the vulcanizates could be affected.
