Abstract
The disclosure features structural tiles and methods for forming such tiles, the tiles including a tile body featuring one or more polystyrene materials, and a coating featuring an epoxy resin and an aggregate material, disposed on at least one surface of the tile body, where the structural tile has a dry coefficient of kinetic friction of at least 0.75 and a wet coefficient of kinetic friction of at least 0.70, and where the dry coefficient of kinetic friction is larger than the wet coefficient of kinetic friction by 0.05 or less.
Claims20
A structural tile, comprising:
- a tile body comprising one or more polystyrene materials;
- and
- a coating comprising an epoxy resin and an aggregate material, disposed on at least one surface of the tile body,
- wherein the structural tile has a dry coefficient of kinetic friction of at least 0.75 and a wet coefficient of kinetic friction of at least 0.70;
- and
- wherein the dry coefficient of kinetic friction is larger than the wet coefficient of kinetic friction by 0.05 or less.

A method for producing a structural tile, the method comprising:
- dissolving one or more polystyrene materials in acetone to generate a polystyrene solution;
- placing the polystyrene solution into a mold;
- positioning a mold cap comprising a plurality of extensions relative to the polystyrene solution so that the plurality of extensions extend at least partially into the polystyrene solution;
- evaporating the acetone from the solution to form a solid tile comprising a plurality of pores in a body of the tile;
- and
- applying a coating comprising an epoxy resin and an aggregate material to at least one surface of the tile body.
