Abstract
A rigid shaped product is produced from organic or inorganic solid particulate materials, preferably waste materials by mixing the solid particulate materials with a non-toxic composed of an aqueous dispersion of a blend of acrylic and polyurethane resin which forms a self-crosslinking composition resin material in a thermoplastic state to form a flowable mixture. The flowable mixture is then formed into a desired shape such as a flat panel or sheet, by molding, extrusion, or injection molding, and cured to thermoset the resin material and form a rigid, shaped product such as a construction board.
Claims15
A method of producing a rigid, shaped product comprising the steps of:
- introducing organic or inorganic solid particulate material into a mixing chamber;
- introducing a non-toxic resin material comprising an aqueous dispersion of a blend of acrylic and polyurethane resins which forms a self-crosslinking composition into the mixing chamber at a first temperature at which the resin material is thermoplastic;
- mixing the thermoplastic resin material and particulate material together to form a flowable mixture;
- forming the flowable mixture by pressing, molding or extruding into a predetermined shape;
- and
- curing the shaped mixture to thermoset the resin material and form a rigid, shaped product having a density in the range of 530-900 kg/m3, a tensile strength perpendicular to the principal plane of the product in the range of 0.2-4.2 MPa, a tensile strength parallel to the principal plane of the product in the range of 8-11 MPa, and a modulus of elasticity perpendicular to the principal plane of the product in the range of 3000-3700 MPa.
