Polyurethane Patents (Class 428/160)
  • Patent number: 4547526
    Abstract: In order to improve the flame-protection effect without substantially impairing the mechanical properties of the articles covered with the flame protection agent, the flame protection agent is provided with a compound in a proportion by weight of 7.5 to 30% which contains at least one sulfo group or sulfonium ion. This compound is preferably a water-soluble ammonium salt. As binder there is used an aqueous solution or aqueous dispersion of an organic material, particularly of an acrylate or of a polymer or copolymer having a base of acrylic acid ester. It is particularly advantageous if substantially open-cell polyurethane foam having a base of polyether is impregnated with such a flame-protection agent which contains an ammonium salt of an aminosulfonic acid in a proportion of about 12%. Polyurethane foams impregnated in this manner are particularly well suited for use in cushionings of articles or in premises for which class B1 fire protection is required.

  • Patent number: 4539241
    Abstract: A procedure for manufacturing a building element, such as a door, wherein the surface sheets of the element are affixed to a frame and between the sheets is placed an insulation. The insulation consists of polyurethane, which is injected into the interspace of the surface sheets so that it becomes glued fast to the sheets and to the frame. By the aid of the invention a rigid, tightly sealed and light weight building element is obtained. In another embodiment, at least one surface sheet is provided with apertures which are each covered with a sheet part formed in a plane separated from the surface sheet. A supporting frame is installed between the surface sheet and the edges of the sheet part, and the component parts are all bonded fast together by the polyurethane insulation.

  • Patent number: 4477505
    Abstract: A structure for absorbing wave energy, particularly acoustic wave energy, which includes a first essentially planar surface against which wave energy is directed and a second essentially planar surface generally parallel to and spaced from the first surface. Wedge-shaped elements of sound-absorbing material are disposed between the planar surfaces. All of the wedge-shaped elements, which may be of triangular cross section or pyramidal, have generally flat base portions which form said first planar surface against which wave energy is directed. The apex portions of the wedge-shaped elements are in substantial abutment with the second planar surface. The invention has utility in anechoic applications; however, in contrast to prior art structures of this type, the apex portions of the sound-absorbing material face away from incident wave energy rather than facing toward it.

    Abstract: This invention relates to a method of making a foam-containing structure which includes placing and suitably retaining a respective first shaped sheet in each of first and second complementary parts of an open mould. Each sheet includes at least one layer of fibrous material. A further respective shaped sheet is placed and suitably retained upon each first sheet. Each said further sheet comprises a layer of fibrous material and an impervious membrane adhering thereto. When the two mould parts are closed together a foamable material is introduced into a cavity formed between the sheets and is then caused to expand, whereupon each membrane is caused to adhere to its adjacent first sheet but prevents penetration of the expanding material into that sheet.

    Abstract: The present invention is directed not only to a method for processing composite sheet material comprising a substrate to one flat surface of which a facing has been laminated but also to the resulting article of manufacture. The process permits the facing material to be shaped to a predetermined, curvilinear configuration. This result may be accomplished by incising a groove in that surface of the substrate opposite the surface thereof to which the facing is laminated so as to provide a freeform span of the facing. Adhesive is applied to selected portions of the substrate, and a predetermined charge of foam forming reactants are deposited along the groove. Thereupon the freeform span is bent to the desired configuration and, if required, so maintained while the foam forms and the adhesive sets.

  • Patent number: 4188428
    Abstract: A lightweight board element includes a lightweight core, such as rigid plastic foam, and a covering layer such as glass fiber-reinforced resin. The upper and lower surfaces of the core are provided with a grid pattern made of up narrow grooves for improving stiffness and surface strength. The lower surface is provided with a further grid pattern of wider grooves which offer improved resistance to distortion. The cover layer is bonded to the core in a mold and the cover layer extends over the side edges of the core. The board uses relatively inexpensive materials and has excellent properties. The board element is particularly suited to the fabrication of a table tennis table in which case the grid pattern of narrow grooves in the upper core surface provides excellent ball bounce characteristics.

  • Patent number: 4105816
    Abstract: A decorative relief finished surface is formed by applying to the surface of an object or substrate to be patterned an undercoat of coating material to a predetermined thickness, and forming an uneven pattern having a variety of projections on coated surface a plurality of times with a rolling device having a plurality of convex parts of curved continued, disconnected or perforated line shape which are formed in a random manner, with the intervals between the convex parts being substantially equal to each other, or by spraying coating material with a spray gun so as to form a multiplicity of projections of varying height. Then, the top portions of the projections of the partially hardened surface which extend beyond a predetermined height are pressed with a pressing roll, such that the projections are uniformly flattened to a predetermined thickness while the rest of the convex parts are left unflattened. The pressing roll is made of a hard or semi-hard, air-permeable, porous material.
