Problems solved by technology

The disadvantage of this method is that due to the strong binding force between the montmorillonite sheets, if the polymer is directly inserted into the montmorillonite sheets, it is easy to produce montmorillonite sheet aggregation, causing the inhomogeneity of the composite system, beyond the nanometer level, which is no longer a nanocomposite, thus greatly affecting the properties of the composite

Embodiment 1

[0036] Example 1: Dissolve 100 parts of aniline, 10 parts of sulfosalicylic acid and 15 parts of sodium lauryl sulfate in 400 parts of water and stir evenly, then add 2 parts of EuCl 3 The aqueous solution was stirred, and ultrasonically dispersed at room temperature for 30 minutes to form a reverse micellar emulsion; 2 Add the reverse micellar emulsion drop by drop to the organic montmorillonite aqueous dispersion under protection, adjust the temperature to 60°C, disperse the intercalation with magnetic stirring for 2 hours, then lower the temperature, and move the reactants to an ice-water bath at about 0°C. Add 100 parts of ammonium persulfate initiator dropwise to initiate polymerization of polymer monomers, and add 3.5 times the amount of rare earth ion substance after 20 hours of reaction. Sodium hydroxide solution is added as a precipitant for rare earth nanoparticles, filtered and washed to obtain montmorillonite / Eu(OH) 3 / Polyaniline ternary nanocomposite.

Abstract

The invention discloses a method to manufacture montmorillonite / rare earth particle / polymer ternary nm compounding material. The layer inserting of rare earth particle and the making of the monomer polymerizing with compounding material of the invention are taken synchronistically. The organic modification of the abio-nm particle and the dispersing process in the ahead-driving body are canceled, thus, the manufacturing time is shortened. It is easy to operate and has high production efficiency.

Description

technical field [0001] The invention relates to a nanocomposite material mainly composed of montmorillonite, in particular to a ternary composite material composed of montmorillonite, a polymer and rare earth nanoparticles and a preparation method thereof. Background technique [0002] Montmorillonite can be used as adhesives, absorbents, fillers, catalysts, detergents, enhancers, etc. Thickeners, etc., are widely used in the fields of industry, agriculture, medicine, and environmental governance, and are known as "clay with thousands of uses", "universal clay", and "living minerals". The special properties of montmorillonite and its wide application have attracted the attention of chemists, and many new products using montmorillonite as raw materials have come out, but most of them are still elementary products, and the resource utilization level of montmorillonite is not enough. Since PA6 / montmorillonite composites were synthesized by intercalation polymerization for the ...
