METHOD FOR PREPARING ORGANOCLAY NANOCOMPOSITES USING SUPER CRITICAL FLUID

摘要

The present invention relates to a method of manufacturing the organic-inorganic nanocomposite according to that, in particular, the compounding method according to the manufacturing method of the layered clay mineral or layered clay compound to oil is dispersed in the polymer resin-inorganic nanocomposite, using a supercritical fluid the present invention relates to a method for producing continuously.; The present invention relates to a production method of, and inserted into an interlayer of the molten clay compound layer polymer chains of and the layered clay compound organophilic the polymer matrix to be produced it by separation by mechanical mixing dispersion nanocomposite For this purpose, a) In the step of groups of the polymer matrix and the organophilic layered clay compound added solvent injection portion, and a solvent recovery unit or stripping plant continuous kneader; And b) it provides a continuous method of producing the nanocomposite, comprising mixing the organophilic layered clay compound and the polymer matrix in a supercritical state of the solvent by injecting the low molecular weight solvent to said continuous kneader.; Nanocomposite production method of the present invention is the selection according to the low molecular weight solvent to the layered clay compound organophilic and polymer matrix, and a continuous kneader can control the dispersion into a desired shape while adjusting the degree of pressure change and kneading a commercially available which in the a continuous production process.
