Flame resistant material and resultant products
Disclosed herein are compositions, formulations, applications, and methods of making a fire resistant material. The fire resistant material is a transparent acrylic material that incorporates a primary polymer, nanostructured fillers, and crosslinkers. The nanostructured filler is polyhedral oligomeric silsesquioxane (POSS) or a POSS derivative that has a cage like structure. The fire resistant material may also include various components such as brominated additives and phosphorous based synergists. The fire resistant material may be used for various applications including wall claddings and glazings.
1. A transparent fire resistant material comprising:
a first polymer, wherein the first polymer is acrylic, acrylic glass, poly(methyl methacrylate) (PMMA), acrylic resin, plastics, or combinations thereof;
a nanostructured filler, wherein the nanostructured filler is polyhedral oligomeric silsesquioxane (POSS), wherein the polyhedral oligomeric silsesquioxane has a methacrylate or acrylate end group attached to each of the 8 corners of the silsesquioxane structure;
at least one crosslinker;
at least one UV inhibitor;
at least one mold release component;
at least one or more radical source;
at least one polymer inhibitor, wherein the polymer inhibitor is hydroquinone;
at least one polymerization initiator;
at least one brominated additive; and
at least one phosphorous based synergist, wherein the synergist is 9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10 oxide (DOPO).
2. The fire resistant material of claim 1 wherein the weight percent of first polymer to the total composition ranges from 45-52% (w/w).
3. The fire resistant material of claim 1 wherein the weight percent of POSS to the total composition ranges from about 0.1% to about 5% (w/w).
4. The tire resistant material of claim 1 wherein the weight percent of crosslinker to the total composition ranges from about 0.5%-1.0% (w/w).
5. The fire resistant material of claim 1 wherein the weight percent of polymer inhibitors to the total composition ranges from 0.001%-0.2% (w/w).
