摘要：本论文主要是测试了不同填料对聚氨酯橡胶机械性能的影响、不同填料用量对聚氨酯橡胶机械性能的影响、不同加料顺序对聚氨酯橡胶机械性能的影响、偶联剂对聚氨酯橡胶机械性能的影响这四个方面。由实验得出气相白炭黑、沉淀法白炭黑和炭黑对聚氨酯橡胶都有较好的补强效果，而硅藻土对于聚氨酯橡胶的补强效果稍差，是半补强填料。在不同炭黑用量对于聚氨酯橡胶性能的比较中，可以得出加入30份炭黑制得的聚氨酯橡胶的机械性能性对较佳。炼胶过程中，将DCP先于填料加入相较填料先于DCP加入，不但加工性能有所提高，机械性能也有显著的提高。加入偶联剂后，聚氨酯橡胶的机械性能有了明显的提高。5350

Effect of Fillers on Mechanical Properties of Polyurethane Rubber
Abstract: The experiments test the effects of different fillers on the mechanical properties of PUR, the effects of different content of fillers on the mechanical properties of PUR, the effects of different feeding sequence on mechanical properties of PUR, the effects of coupling agent on the mechanical properties of PUR influence. Experimental results indicate that: fumed silica、Precipitated silica and carbon black has good reinforcing effect of polyurethane rubber. And diatomite hasn’t good reinforcing effect of polyurethane rubber, so it is the semi reinforcing filler. From effect of different amount of carbon black of polyurethane rubber, we know that the mechanical properties of PUR with 30 parts of carbon black are good. In the process of mixing polyurethane rubber, adding DCP into PUR before adding fillers can improve the processing performance and mechanical properties. After adding the coupling agent, the mechanical properties of polyurethane rubber has been significantly improved.
