A novel strategy of jet technology is developed to prepare rubber composites filled with carbon black.The carbon black aggregates were first dispersed into water by ultrasonic effect.Then in the high speed jet flow field

the carbon black suspension was dispersed into natural rubber latex.The carbon black particles were dispersed microscopically in the natural rubber latex by the turbulent tensile and shear force.High performance of natural rubber/carbon black composites is gained by latex compounding technique.The results showed that carbon black particles were uniformly dispersed into natural rubber by jet technology.And the interaction between carbon black was weakened

and the carbon-rubber interaction was enhanced.Compared to the properites of composites prepared by dry method

the tear strength and rebound of the composites prepared by jet technology were increased by 78% and 20%

respectively.The DIN abrasion loss of the obtained composites was decreased by 33%.The dynamic mechanical properties showed that the composites prepared by jet technology had lower loss factor at about 60℃.
