Abstract：
 The present invention relates to composite polymer material performance improving technology. The liquid natural rubber slurry contains natural latex and carbon nanotube (CNT) and has total solid content of natural latex and CNT in 5-30 % and weight ratio between CNT and dry natural latex of 1-50 %. The liquid natural rubber slurry is prepared through surface treatment of CNT for hydrophilicity; mixing with dispersant and deionized water to obtain water suspension of CNT; regulating the pH value of the suspension to 9-12; and finally mixing with natural latex to obtain the liquid natural rubber slurry with added CNT. The liquid natural rubber slurry with homogeneously dispersed CNT is used in preparing CNT modified rubber powder and CNT modified sulfurized rubber products with greatly raised mechanical, electrically conducting, heat conducting, antistatic and other performance.
