The invention discloses a
montmorillonite-
styrene butadiene rubber
nanocomposite material. The
montmorillonite-
styrene butadiene rubber
nanocomposite material is a composition of
macromolecular compounds. The
montmorillonite-
styrene butadiene rubber
nanocomposite material comprises: by weight, 416 parts of butadiene-styrene
emulsion having
solid content of 24%, 10 to 120 parts of organic modifiedmontmorillonite fluid suspension, 1 to 8 parts of
adhesive emulsion, 0.2 to 20 parts of a
coupling agent, 0.2 to 2 parts of an
antioxidant, 1.5 to 8 parts of a flocculating agent, 2000 to 5000 parts of an inorganic salt-flocculating agent
aqueous solution, an appropriate amount of an inorganic acid and an appropriate amount of an inorganic base. A preparation method of the montmorillonite-styrenebutadiene rubber nanocomposite material comprises thr following steps of 1, carrying out preprocessing of a part of the raw materials, 2, carrying out premixing of a part of the raw materials, 3, carrying out preliminary
flocculation, 4, adding
adhesive emulsion into flocculates obtained by the step 3, and 5, carrying out secondary
flocculation. The montmorillonite-
styrene butadiene rubber nanocomposite material and the preparation method thereof have the advantages that flocculated
styrene butadiene rubber particle sizes are large; a montmorillonite reinforcement effect is improved obviously; vulcanizate
wear resistance is improved several times; an original
styrene butadiene rubber
polymerization technology is not changed but processes and a formula are improved simply; and continuous industrialized production is realized.
