交联方式对超高分子量聚乙烯性能的影响研究

Study of the Influence of Crosslinking Methods on UHMWPE Properties

中文摘要英文摘要

分别以DCP引发交联、DCP与KH-570共同引发交联两种工艺对超高分子量聚乙烯进行交联改性,以提高其表面硬度、抗磨粒磨损能力。通过改变DCP、KH-570的用量、成型温度,测试了交联UHMWPE的凝胶率、邵氏硬度、拉伸强度、耐磨性等性能。实验结果表明:两种改性工艺均可以使UHMWPE发生交联反应,凝胶率不同,其中单独采用DCP引发的交联反应制品的凝胶率更大,从改善表面硬度、磨损性角度而言,DCP与KH-570共同引发交联工艺更好。

It uses two methods which initiates cross-linking by DCP only or both DCP and KH-570 to modify UHMWPE in order to improve the properties such as surface-hardness and abrasive wear resistance . By changing the dosage of DCP and KH-570, the temperature of molding, it tests the data such as gel rate of UHMWPE, Shore D hardness, tensile strength and wear resistance. The result is given below. Both processes can gain cross-linking UHMWPE, but cross-linking rates are different. The cross-linking rate is higer in the first process, but the second one is better from the data of surface-hardness and abrasive wear resistance .
