POLYMER COMPRISING MESOPOROUS FLAME RETARDANT

摘要

Embodiments of the disclosure generally provide flame retardant compositions and methods comprising organic polymers, mineral fillers, high surface area mineral fillers and process aids. Compositions of the disclosure additionally are comprised of high surface area hydrated metal carbonate fillers, including the mesoporous amorphous magnesium carbonate filler Upsalite. The filler's porous structure and high surface area provides high water capacity, enhanced physical and chemical interaction with a polymer in composite, lower by weight loadings of filler in a composite, as well as effective flame retardancy.

主权项

1. A method of producing a flame retardant object, comprising:
milling a mesoporous amorphous magnesium carbonate filler to a particle size between about 0.010 microns and about 25 microns; hydrating the filler in a humid environment; compounding the hydrated filler with a polymer, to form a flame retardant composite wherein the weight percent of the filler in the flame retardant composite is between about 5 percent and about 50 percent by weight of the flame retardant composite; and forming an object from a flame retardant composite.
