Production of polymer-inorganic foam

Abstract

Abstract PRODUCTION OF POLYMER-INORGANIC HYBIRD FOAM CONSTRUCTION MATERIALS, BY A PROCESS WHICH COMPRISES WHIPPING AIR INTO A RESIN IMULSION, SUCH AS A POLYVINYL ACETATE EMULSION, ESTABLISHING A PRE-FOAM OR RESIN EMULSION BUBBLES, ADDING AN INORGANIC PHASE, WHICH CAN BE FOR EXAMPLE PORTLAND CEMENT OR GYPSUM, OR A COMBINATION THEREOF, IN THE FOAM OF PARTICLES SO AS TO SUSPEND SUCH INORGANIC PARTICLES ON THE FOAM BUBBLES WITHOUT PRICIPITATING OUT SUCH PARICLES, POURING THE RESULTING POLYMER-INORGANIC HYBIRD FOAM INTO SUITABLE MOLDS, PERMITTING SUCH FOAM TO SET TO A SOLID SELF-SUPPORTING MASS, USUALLY TAKING PLACE IN A SHORT PERIOD OF THE ORDER OF ABOUT 10 TO ABOUT 30 MINUTES, AND HARDENING THE INORGANIC PHASE TO FULLY SET THE HYBIRD FOAM, AND FORM A HARD RIGID POLYMER-INORGANIC HYBIRD FOAM WHICH IS LOAD SUPPORTING, FOR RESISTANT, THERMALLY INSULATING, AND OF LOW DENSITY. SUCH HYBIRD FOAM WHICH IS STRONG AND LIGHTWEIGHT, IS PARTICULARY USEFUL FOR PRODUCTION OF WALL, FLOOR OR ROOF PANELS IN CONSTRUCTION OF BUILDING AND HOMES.
