Abstract
A method for preparing carbon nanotubes graphene modified aqueous polyurethane coatings and adhesives, which includes the steps of: (a) preparing carboxylated carbon nanotubes graphene nano-sheets; (b) mixing polytetrahydrofuran ether glycol with isophorone diisocyanate for reaction in the presence of dibutyltin dilaurate; and then adding 2-sulfobenzoic anhydride, carboxylated carbon nanotubes and graphene sheet into the mixture and allowing reaction under 90° C. for 2 hours to obtain a polyurethane prepolymer A; and (c) adding chain extender and acetone into the prepolymer A and allowing reaction under 65° C. to 75° C., adding D-panthenol and 2,4,6-trihydroxy benzoic acid and allowing reaction under 75° C. to 85° C. for 0.5 to 2 hours; then adding triethylamine and benzamide for neutralization and allowing reaction for 30˜50 min; and finally adding water for emulsification to obtain carbon nanotubes graphene modified aqueous polyurethane coatings and adhesives, which is environment-friendly and can be used as adhesives on plastic, glass, paper-based materials and textiles.
