Abstract:
    The present invention is preparation process of nanometer polyurethane composite particle for use in polymer material, and belongs to the field of polymer material modifier preparing technology. Nanometer silica particle, polytetramethylene ether glycol-toluene diisocyanate as the prepolymer of polyurethane, n-butyl acetate solvent are mixed homogeneously under nitrogen protection and through magnetically stirring and heating to 60-90 deg.c to react for 1-4 hr, before suction filtering and washing the filtered solid phase product for several times to obtain the nanometer polyurethane composite particle. The nanometer polyurethane composite particle of the present invention is suitable for being added into polymer material base to raise its physical and chemical performances.
