Graphene oxide and water soluble copolymers of vinyl monomers leather tanning and preparation method

The present invention discloses a graphene oxide with water soluble copolymers of vinyl monomers leather tanning agent, made from a material according to the parts by mass: nano-sheet graphene oxide dispersion liquid 20 to 30 parts, 0.5 to 1 part oxidizing agent, monomer mixed solution 60 to 80 parts, 20 to 30 parts initiator; the present invention also discloses a method for preparing a graphene oxide with water soluble copolymers of vinyl monomers leather tanning agent, the present invention is an aqueous solution of a radical polymerization reaction achieved graphene oxide structure with double water-soluble vinyl monomer to radical copolymerization, the resulting copolymer contains both oxide and graphene nano-sheet aqueous vinyl structural units, but also so that the graphene oxide nanoplatelets the smaller, more evenly distributed, after penetration into the leather between the collagen fibers, chemical bonds and nano-size effect hydration, thereby obtaining a tanning effect of leather fibers may be used alone as a leather tanning agent.
