The anti-heating aging property of PP, montmorillonite/polypropylene and ongano-montmorillonite/polypropylene composites (OMMT/PP), in which MMT is modified with 1-octadecyl-3-methylimidazolium chloride was studied. Results indicate that the tensile and bending strength of OMMT/PP is enhanced about 7.3% and 17.5% respectively, and impact property is improved up to 54%, comparing to neat polypropylene. After 4 cycles, in which 5 days are considered to be one cycle of the heating aging process, the mechanical properties retention rate, mass loss ratio, and the color variation of composites were all investigated. It is found that the composites has excellent mechanical properties retention rate, part of the properties have even been improved after heating aging. In addition, the loss of mass is very little, and there is no obvious color change of OMMT/PP samples in heating aging process. All these imply that OMMT/PP composites have excellent mechanical properties and exhibit predominant anti-aging property.
