摘要： A syntactic structural foam product in flat sheet form or curved three-dimensional form adaptable to such uses as a light weight structural core for composite laminates, is made of a mixture of hollow ceramic microspheres and dry resin powder, of either thermosetting or a high-temperature thermoplastic resin, distributed in the interstices of the mass of microspheres for integration of the mixture into desired form upon heating and cooling. Resin powder collected as a waste by-product from resin coating materials can be recycled in the production of the desired product. The foam product is produced by first intermixing the microspheres and powdered resin by physical agitation of the mixture and depositing the mixture as a layer over a surface having a release agent thereover within a dimension defining region between boundary members and then supplying heat with or without pressure to the layer at a temperature and for a time period sufficient to effect a melting of the resin powder and thereafter cooling the resin in a hardened condition to integrate the mixture into the product desired after which the product is withdrawn from the forming zone. Reinforcing elements such as glass or carbon fibers can be selectively included in the mixture for predeterminable desired physical and mechanical properties.

摘要： A method and apparatus or system for the continuous manufacture of building element consisting of a self-supporting framework of tightly compressed solid particles and a foaming material in the shape of a foamed plastic material, includes the use of a filling station where mold bottoms are placed in series on a roller conveyor, assembled with sidewalls and passed along a guide section, wherein particle-shaped filler is supplied from a silo while premixed foam material is injected into the material through nozzle tubes and the components are mixed before being injected into the mold and compressed. After placing of a top wall on each of the molds, these are passed under a roller conveyor, and while the molds are moved ahead between the roller conveyors and possibly roller conveyors outside the sidewalls, the foam material binds the particles together to form a monolithic unit which will set before the molds leave the roller conveyors. After demolding of the formed flow of the material, it is cut by a cutting mechanism into the required lengths and the molds are carried back to the filling station. The product is a building element of firmly compressed hard expanded burnt clay particles forming a coherent supporting skeleton of abutting particles bound together by a cured polyurethane foam in only an amount sufficient to fill the cavities between the compressed particles.

摘要： An improved method for manufacturing a foam-filled polyurethane foam bun from foam particles having uniformly dispersed therewith large amounts of solid material bonded together with new polyurethane foam is described. The method comprises uniformly applying a liquid flexible polyurethane foam-forming material to a dispersion of foam particles and solid material to provide a blend, distributing the blend within a mold, and foaming and curing the foam-forming material by a plurality of steaming steps wherein the mold is flipped from a first to second position between steaming steps. The foam buns have a uniform density gradient. Foam buns are disclosed having a variation in density across the foam bun. There is also disclosed an improved char-forming foam obtained as a result of using boric acid in the foam-forming formulation.

摘要： A panel comprising fillers embedded in a closed cell expanded phenolic resin is made by making a mixture, which is initially fluid, or phenolic resin, a hardening agent, a surface active agent and a porogenic agent, which has a boiling point above ambient temperature and below the polycondensation temperature of the mixture. This liquid mixture is mixed with fillers, for example balls or microspheres of glass or expanded material such as polystyrene. The resulting mixture is placed in a mould, only partially filling the mould, and heated progressively to a temperature in the neighborhood of the boiling point of the porogene agent, while evacuating the mould, and held at that temperature until the mixture has expanded to fill the mould. The temperature is then progressively increased to the polycondensation temperature to harden the expanded mixture.

摘要： When producing insulating units, in particular building units, plaster of Paris was previously poured into the mold, bloated polystyrene pearls being prekneaded into said plaster. Plaster of Paris has also been poured into molds, wherein a lining of an aggregate of fused, bloated polystyrene pearls were prearranged. The bloated polystyrene pearls according to the invention are first densely packed in the mold, whereupon plaster of Paris, cement or another hydraulic binding material is filled into the mold through a net or a perforated plate, said net or perforated plate keeping the pearls densely packed during the casting so as to ensure that they do not reposition as a consequence of their buoyancy in the cast, liquid binding material.
