Abstract
Compositions and methods for producing smoke suppressants are disclosed. The smoke suppressant molecularly encapsulates a naturally-occurring inorganic substrate, such as expanded volcanic ash. These intercalated smoke suppressant compositions have particular utility for smoke suppression in polyvinyl chloride (PVC), both flexible and rigid compounds as well as other polymeric resins and materials.
Claims12
A smoke suppressant composition comprising:
- a substrate formed from volcanic ash;
- a multi-functional coupling agent bonded to the substrate;
- and
- a smoke suppressant disposed on at least a portion of the substrate, wherein the smoke suppressant is ammonium octamolybdate (AOM) having a thickness between about 1 nm to about 1 micron.
