摘要
根据胶料自粘性的形成过程，通过门尼粘度、粘合强度、界面粘合强度和强伸性能的测定，分析了影响三大通用橡胶自粘性的因素。ＳＢＲ自粘性差的重要因素是分子的扩散能力小，其次是粘滞阻力低；ＢＲ自粘性差的决定性因素是粘滞阻力低，扩散能力只是其必要条件。
Abstract The effective factors on the tackiness of 3 main general purpose rubbers were analysed based on the determination for their Mooney viscosity,adhesion strength,boundary adhesion strength and tensile properties.It was found that the poor tackiness of SBR resulted mainly from its low molecular diffusion,and minorly from its low viscous resistance;the poor tackiness of BR was determined by its low viscous resistance,and the high molecular diffusion was only one of the necessary conditions to obtain good tackiness.The tackifying agents TKO and TKB possessed different tackifying effects on SBR and BR.
