Problems solved by technology

The water acts to smother the flame by diluting and / or excluding oxygen and flammable gases, and a heat insulating material can form on the surface of certain polymeric materials containing magnesium hydroxide when in contact with the flame, reducing the availability of potentially flammable decomposition products to the gas phase where combustion occurs.

Embodiment Construction

[0113]Methods and methodologies used to produce nanoplatelets and other forms of metal hydroxides are provided. The base materials used to make the process feedstock include, for example, a metal chloride (e.g., magnesium chloride (MgCl2)) and sodium chloride (NaCl). Suitable base materials include commercially available bulk forms of sodium chloride and metal chlorides. A suitable form of magnesium chloride is marketed as FreezGard® magnesium chloride available from North American Salt Company of Overland Park, Kans. While magnesium chloride is particularly preferred, other sources of soluble magnesium ion can also be employed, for example other magnesium halides such as magnesium bromide and magnesium iodide, magnesium nitrate, and magnesium sulfide. Likewise, other metal ions (in the form of metal chlorides or other soluble metal ions), including, but not limited to, beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), radium (Ra), scandium (Sc), titanium (T...

Abstract

Nanoplatelet forms of metal hydroxide and metal oxide are provided, as well as methods for preparing same. The nanoplatelets are suitable for use as fire retardants and as agents for chemical or biological decontamination.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 908,144 filed Mar. 26, 2007; and U.S. Provisional Application No. 60 / 837,791 filed Aug. 11, 2006, the disclosures of which are herein incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]Nanoplatelet forms of metal hydroxide and metal oxide are provided, as well as methods for preparing same. The nanoplatelets are suitable for use in paper retention, drainage, and opacity, as fire retardants in plastics, rubbers, coatings and textiles and as agents for chemical and biological preventive and decontamination, in electronics and plasmonics.BACKGROUND OF THE INVENTION[0003]Metal hydroxides are useful in a variety of applications. For example, magnesium hydroxide (Mg(OH)2), is employed as flame retardant in various polymer compositions. Magnesium hydroxide has advantages over certain other flame retardants in that it is both acid-free and halogen-free...
