The invention discloses a preparation method of
chitosan-
polyurethane ionic compound elastomeric material, which comprises the following steps: polyisocyanates reacts with
polymer polylol and then reacts with
diol or
diamine,
organic solvent and
ionization reagent are added in the reactants to react with water for generating anionic waterborne
polyurethane and further performs the ionic recombination reaction with cationic
chitosan water solution to obtain the
microemulsion or latex of
chitosan-
polyurethane ion composite, and finally the
microemulsion or latex of chitosan-polyurethane
ion composite is dried and solidified to obtain the chitosan-polyurethane ionic compoundelastomeric material. The chitosan-polyurethane ionic compoundelastomeric material has the advantages of good
mechanical property, easy
processing, good oil-
water resistance property, good cohesive property with parent
metal, controllable performance, good
biocompatibility, biodegradable property, high
biological activity, good blood contact property, good bacteriostatic property, good
antibacterial property, and the like, can be applied in fields of mechanical industry,
building industry, sport,
medical treatment, and the like, and especially has wider purpose in aspects of life
science research, medical materials and medical appliances.
