Characteristic
Montmorillonite, the main component of montmorillonite, is composed of two layers of Si O tetrahedron and a layer of Al-O eight surface. It contains mainly sodium ions, magnesium ions, calcium ions, followed by potassium ions, lithium ions and so on. The organic modification of nano montmorillonite in order to come into layers: layer hydrophobic layer, so that the polymer and montmorillonite has better interface compatibility. Has the characteristics of good dispersion properties, can be widely used in the polymer industry as an additive nano polymer material, improve impact resistance, fatigue resistance, dimensional stability and gas barrier properties, so as to enhance the comprehensive physical properties of polymer materials, and improve the processing performance. Applications in polymers can be added at the time of polymer and can also be added at the time of melting (usually by screw blending).


application
Montmorillonite - the most commercial inorganic polymer thickener


Inorganic polymer thickeners generally have three layers of layered structure or an expanded lattice structure, and the two most commercial uses are montmorillonite and diopyroxite. The thickening mechanism of inorganic polymer is dispersed in water, the diffusion of metal ions from the wafer to the outside, with the hydration, it swells to the last piece of crystal separated completely transparent colloidal suspension which results in the formation of anionic lamellar structure crystal and metal ions. In this case, the crystal has a negative charge on the surface, and its edge angle has a small amount of positive charge due to the appearance of the lattice fracture surface. In a dilute solution, the negative charge on the surface is larger than the positive charge at the edge angle, and the particles are mutually exclusive, so it will not produce thickening. With the addition of the electrolyte and the increase of the concentration, the surface charge of the crystal decreases with the increase of the ionic concentration in the solution.  At this time, the main interaction changes from repulsive force between the lamellae and lamellar boundary between negatively charged surface angle of positive charge attraction, parallel lamellae perpendicular to cross linking together to form the so-called "box type structure of space", causing swelling produce gel so as to achieve the thickening effect. The further increase of ion concentration will destroy the flocculation of the structure and reduce the consistency. These thickeners are mainly used for the thickening of toothpaste, shampoo, conditioner, cream, emulsion and antiperspirant. The consistency increases rapidly with the increase of concentration and then tends to slow, and the rheological morphology is thixotropic. In addition to the thickening performance, there is a stable emulsion and suspension effect in the system. Its modifier is mainly quaternary ammonium salinization, after modification, it has an affinity for oil and can be used in a system with more oil content.
