ARTICLE OF MANUFACTURE CONTAINING A FLAME RETARDANT FILLER PREPARED FROM A BRIDGED POLYSILSESQUIOXANE |
摘要 |
A bridged polysilsesquioxane-based flame retardant filler imparts flame retardancy to manufactured articles such as connectors and other articles of manufacture that employ thermosetting plastics or thermoplastics. In an exemplary synthetic method, a bridged polysilsesquioxane-based flame retardant filler is prepared by sol-gel polymerization of a monomer having two or more trialkoxysilyl groups attached to an organic bridging group that contains a fire retardant group (e.g., a halogen atom, a phosphinate, a phosphonate, a phosphate ester, and combinations thereof). Bridged polysilsesquioxane particles formed by sol-gel polymerization of (((2,5-dibromo-1,4-phenylene)bis(oxy))bis(ethane-2,1-diyl))bis(tri-methoxysilane), for example, and follow-on sol-gel processing may serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant. |

1. An article of manufacture, comprising:
a housing comprising a plastic material, wherein the plastic material includes a flame retardant filler comprising a bridged polysilsesquioxane prepared by sol-gel polymerization of a monomer comprising two or more trialkoxysilyl groups attached to an organic bridging group, wherein the bridging group contains a fire retardant group selected from a halogen atom, a phosphinate, a phosphonate, a phosphate ester, and combinations thereof. |
