Abstract

A nanometre-class polymer/laminated inorganic substance composite material features that it is prepared by use of the millstone-shaped force chemical reactor, which has a unique 3-D shear structure to provide strong squeeze-shear force field for grinding inserting, dispersing, and mixing to prepare the polymer/laminated inorganic substance composite powder, and then the said nanometre-class composite material is prepared by the universal processing method.

Description

1. Technical field [0001] The invention relates to a polymer / layered inorganic nanocomposite material and a grinding disk shearing preparation method thereof. 2. Background technology [0002] The polymer / layered inorganic nanocomposite material is a kind of nanocomposite material formed by dispersing the layered inorganic filler with weak interlayer structure in the polymer matrix with a nanometer layer thickness by appropriate means. According to the degree of dispersion of layered inorganic fillers in the matrix resin, it can be divided into intercalation type and exfoliation type. Due to the combination of the advantages of polymers and layered inorganic materials, it is economical and effective to make layered inorganic materials with potential nanostructures fully obtain the optical, electrical, magnetic, thermal, force, barrier, chemical activity and catalytic properties. For more than ten years, it has been highly valued by scholars and business circles all over the...
