Abstract: A new type two-component polyurethane paving material used in playground was prepared from liquefied diphenylmethane–4, 4′–diisocyanate (MDI), alkyolamide modified montmorillonite (AOMMT) and organo-rare-earth composite catalyst (REC) . The formulations and properties of product were studied. The results showed that at normal temperature and under the action of REC, AOMMT could replace 3, 3′–dichloro–4，4′–diamino–diphenyl methane, alias methylene–bis–ortho–chloroaniline (MOCA) and there was no poisonous substance such as TDI, MOCA, Pb and Hg in this new material. It could eliminate the poison of these substances in the preparation and use of the polyurethane paving material. Its properties could satisfy the demands of Chinese national standard of GB/T14833–93《Synthetic–Rubber Sports Track》.
