摘要
以填充型粉末橡胶的加工性能评价为例,综述了Brabender转矩流变仪在橡胶的密炼机塑炼、混炼、焦烧模拟、挤出等加工性能表征中的应用。由于Brabender转矩流变仪提供了广泛的剪切速率范围和模块化的测试接头,为橡胶的密炼机加工、挤出加工等的模拟和表征提供了可能。研究结果表明,Brabender转矩流变仪的密炼头与工业密炼机具有良好的相关性,可用于表征胶料的密炼机加工特性。填充型粉末橡胶中含有大量已良好分散的填料,其密炼机混炼过程与传统干法混炼存在诸多不同,而复杂口型的挤出特性也有差别,这些特点在转矩流变仪上也表现得非常明显。
The application of Brabender plasticorder in internal mastication, mixing, scorching, and extruding of rubber compounds were reviewed in the paper, based on the evaluation of the processing properties Of filler filled powdered rubber. Since several testing head with wide shear rate range were equipped with Brabender plasticorder, which made it possible for evaluating the internal mixing and extruding properties of rubber compounds. The research results showed that Brabender plasticorder presents good relationship with Banbury internal mixer. As filler has been well dispersed in rubber matrix before mixing, the internal mixing behaviors are much different with that of traditional dry mixing products, and the extruding properties also show difference, both of which could be clearly expressed in the Brabender plasticorder.
