Aluminum coupling agent is used for Diatomite modification .The Diatomite with different content is melt and mixed with polypropylene to prepare Diatomite/polypropylene composites .The modification effects of both the aluminum coupling agent and silane agent on Diatomite are compared to study how the contents of agent and diatomite influence the morphology and tensile properties of the composites . Results show that both agents has the modification effects on Diatomite but the aluminum agent is better than silane .When the content of aluminum is 1% ,the elongation of the composites increases 121 .60% and the strength is upgraded to 64 .05% .
