串联密炼机在能源消耗与胶料性能改善方面有突出优点,它采用啮合型转子结构对胶料进行剪切混炼,混炼效果好,冷却效果良好,适合白炭黑混炼的热履历炼胶控制、转子转数控制等。本文对HF串联密烁机的产量、胶料的性能和动态粘弹性能进行了实验研究,并与普通密炼机进行了对比,结果表明:HF串联密炼机炭黑宏观分散度高,微观分散效果也比一般密炼机好,混炼的胶料扯断强度和扯断伸长率高,胶料在60℃时的动态滞后损失要低于F370混炼的胶料,因此,HF串联密炼机适合绿色环保轮胎高混炼的要求。 相似文献

橡胶密炼机混炼工艺瞬时功率控制法 总被引:2,自引:0,他引:2
橡胶密炼机混炼工艺瞬时功率控制法的理论由3部分组成:橡胶混炼过程的机理、密炼机流理论和混炼过程功率曲线与能量控制法不同,瞬时功率控制法实质上是控制混炼过程中胶料的粘度,确保混炼工艺过程保持最佳状态。因而瞬时功能控制法可监控生产过程,为密炼机混炼工艺的智能控制奠定了基础。 相似文献

Blends of syndiotactic polystyrene (s-PS), thermotropic liquid crystalline polymer (Vectra A-950), and silicone rubber with two different loading levels, have been prepared through melt processing in internal mixer at 285°C. Silicone rubber was used as a compatibilizer for this blend system. The effect of silicon rubber on crystalline, dynamic mechanical, rhelogical, thermal properties, and phase morphology of the (s-PS/TLCP) blend has been investigated in details. With the addition of compatibilizer the viscosity of the blend system increased to an order of magnitude. Dynamic mechanical analysis (DMTA) and differential scanning calorimetry (DSC) results showed that the glass transition temperature (Tg) of the blend, in presence of silicone rubber, shifted towards lower temperature region. From FTIR analysis it is evident that the ‘C=O’ stretching frequency has shifted towards lower side. SEM analysis suggested that, the TLCP domain size is reduced in ternary blend in comparison to binary blend system. 相似文献

AbstractIt is proposed that a non-polar filler can reduce interfacial energies between polar and non-polar polymers. Experiments have been carried out to test this hypothesis using carbon black as the filler in blends of natural rubber (NR) and a nitrile rubber (NBR) with an acrylonitrile content of 45%. Blends of NR–NBR (70/30) were prepared in an internal mixer with varying amounts of carbon black. The dramatic decrease in domain size on addition of carbon black was nonetheless lower than that predicted. Further experiments showed that the amount of carbon black available at the interface for compatibilisation was influenced by preferential incorporation into the lower viscosity elastomer (NBR). Thus, elastomers of similar viscosity should be added to the mixer prior to the carbon black in order to maximise the amount of ‘free’ unwetted carbon black present when the elastomers are blended together. Blending experiments carried out under these conditions resulted in a morphology close to the prediction based on thermodynamic theory. 相似文献
