| Abstract: | The under-track elastic pad（UTEP） in high-speed railway was prepared by the reaction of 4,4′-diphenylmethane diisocyanate（MDI）,combined polyether polyols,foam stabilizers,chain extenders and water.The influence of the relative molecular mass of polyether polyols,types of crosslinking agents and hard segment content on the mechanical properties and static stiffness of UTPE was discussed.UTEP in high-speed railway was prepared by combining special mould and process technology,It is found by test that it can meet the requirement of Temporary Technical Specifications of WJ-8 Fastener. |
| Keywords: | high-speed railway elastic pad polyurethane microporous elastomer |
