摘要
研究了 CO-4 稳定剂对基于超高分子量聚乙烯的聚合物复合材料流变特性的影响。研究表明,在聚合物基质中添加 CO-4 稳定剂会显著影响材料的流变特性及其挤出性。大分子链的构象发生了变化,粘性成分与分散体系的松弛过程不相关,复合粘度增加,从而导致材料的加工性变差。根据 Han 曲线显示,添加 CO-4 稳定剂会导致混合物的混溶性恶化,即所获样品中各组分的相分离增加。
Investigation of rheological properties of extruded composites based on UHMWPE
The influence of the CO-4 stabilizer on the rheological properties of polymer composite materials based on UHMWPE has been studied. It has been shown that the addition of a CO-4 stabilizer to polymer matrices significantly affects the rheological properties of materials and their extrudability. There is a change in the conformations of macromolecular chains, the absence of dependence of the viscous component on the relaxation process of the dispersed system, an increase in the complex viscosity, which led to a deterioration in the processability of the material. Based on the Han curves, it is shown that the addition of a CO-4 stabilizer leads to a deterioration in the miscibility of mixtures, i.e., the phase separation of the components of the obtained samples increases.
