The hydrous kaolin was modified by titanate coupling agent. A series of hydrophilic modified kaolin/polyurethane dispersions were prepared successfully by mechanical blending,mechanical proper-ties and heat resistance of composite material have been studied. The results indicated that the tensile strength of the composites was 24 . 4 MPa with the content of modified kaolin was 2 . 0%,which increasing 53. 1% than the polyurethane,and the elongation at break up to 492%,increasing 9. 6%. The composites were achieved the effect of enhancing and toughening because of the adding of kaolin. Furthermore,the thermal stability was improved.
