Abstract
A structural material of a polystyrene base and the reaction product of the polystyrene base and a solid phosphate ceramic. The ceramic is applied as a slurry which includes one or more of a metal oxide or a metal hydroxide with a source of phosphate to produce a phosphate ceramic and a poly (acrylic acid or acrylate) or combinations or salts thereof and polystyrene or MgO applied to the polystyrene base and allowed to cure so that the dried aqueous slurry chemically bonds to the polystyrene base. A method is also disclosed of applying the slurry to the polystyrene base.
Claims18
A structural material, comprising the dried reaction product of an aqueous slurry, said slurry prior to reaction comprises:
- a) particles of a solid phosphate ceramic composite,
- b) a poly (acrylic acid or acrylate) or combinations or salts thereof, and
- c) polystyrene.
A structural material, comprising the dried reaction production of an aqueous slurry, said slurry prior to reaction comprises:
- a) particles of a solid phosphate ceramic composite,
- b) a poly(acrylic acid or acrylate) or combinations or salts thereof, and
- c) MgO, said MgO is present in the slurry in the amount which exceeds the stoichiometric amount required for reaction of said MgO with all carboxylic functionality of the component b).
