Definitions

  • the present invention relates, in general, to a multi-purpose soundproof panel and, more particularly, to an aluminum foam-based soundproof panel with irregular arrangement of a plurality of open pores different in size and shape, which can absorb sound and/or insulate noise over a wide frequency range as well as can be used as a construction finish material for various edifices.
  • noise Originating from machinery, traffic vehicles, such as cars, trains, airplanes and the like, construction sites, audio instruments, etc., unfavorable sound, that is, noise, is a daily event. It is well known that noise is an injurious factor to personal health by causing hardness of hearing, headaches, uneasiness, etc. In addition, in industrial fields, noise and vibrations from machinery and instruments make a poor environment for workers, giving rise to a serious decrease in productivity and product quality.
  • soundproof structures made from sound-controlling material or soundproofing materials capable of absorbing or insulating sound, such as noise barriers, soundproof partitions and soundproof rooms, are provided for the noise sources, in order to absorb noise and block its propagation.
  • General construction materials such as wood and concrete, synthetic resins, such as polyurethane, polyethylene and polyester, inorganic fiber materials, such as glass wool and rock wool, metal materials, such as perforated metal plate, alone or in combination, are most widely used as soundproofing or sound-insulating materials.
  • Soundproofing or sound-insulating materials are required to show high sound absorption or insulation power over a wide frequency range and superiority in mechanical properties, such as durability, and thermal properties, such as incombustibility or flame retardancy, as well as to be low in production cost with ease in carrying out construction therewith.
  • a multi-purpose, aluminum foam-based soundproof panel comprising at least one aluminum foam panel with a plurality of open pores, wherein the open pores are formed from the closed pores within a mass of aluminum foam by rolling the aluminum foam into a panel, and the aluminum foam panel with a plurality of open pores is bonded with or coated with fibrils, a perforated thin plate, a finish material, paint, a sound-absorbing member or noise insulator or a honeycomb structure on at least one surface or impressed with a pattern on one surface or has resonance hollows therein.
  • the aluminum foam panel with a plurality of open pores useful as a base for the soundproof panel according to the present invention, is prepared by subjecting a mass of aluminum to a conventional foaming process and by then rolling it into a plate.
  • a mass of aluminum is molten in a mold equipped with a heater and a stirrer. After being maintained at an appreciate viscosity with the aid of a viscosity increasing agent, the molten aluminum is added with a foaming agent to produce an aluminum foam with closed pores. When rolling the aluminum foam, its closed pores break into open ones.
  • open pores means the air bubbles which are trapped in not a closed state, but an open state in aluminum foam. Upon foaming aluminum metals, air bubbles form therein, most of which are closed, each providing a closed space. Because the aluminum panels containing such closed pores are now found to fall short of the ability to absorb sound waves, there are needed novel soundproof aluminum panels which are better in absorption of sound and/or insulation of noise. In the invention, the closed pores in aluminum foams are burst into open states by lightly rolling the aluminum foam panels.
  • the rolling with the aim of opening the closed pores may be carried out by pressing the aluminum foams to the extent that the thickness of the aluminum foams is reduced by, for example, about 20-30 %.
  • the rolling reduction is determined depending on the conditions of the resulting aluminum, such as use, thickness, etc. Care should be taken not to compress the pores to flat by increasing the rolling reduction.
  • the aluminum foam panels thus obtained can be ultralight sound-absorbing materials with a pore volume amounting up to 90% in total.
  • Figures 1 and 2 show a soundproof panel coated with fibrils in accordance with a first embodiment of the present invention, in a perspective view and in a cross sectional view, respectively;
  • Figures 3 and 4 show a soundproof panel provided with a perforated thin plate in accordance with a second embodiment of the present invention, in a perspective view and in a cross sectional view, respectively;

When sound waves strike the surface of the aluminum foam panel 10 in such a structure, low frequency sounds are attenuated as they pass through the open pores 12 while medium and high frequency sounds are absorbed in the resonance hollows 530, which absorption is enhanced by the resonance action of the slits. Therefore, the soundproof panel of this structure is superior in noise insulation over a wide range of sound frequencies.

  • a soundproof panel In order to be used for the construction of the ceiling, a soundproof panel is required to have a low weight in addition to being good in sound absorption. Preferable are those which can be used as a construction finish material without application of additional finish materials.
  • Figs. 14 to 17 there are shown soundproof panels 600 which can be used for the construction of the ceiling. Taking advantage of the excellent sound absorption power that an open pore-containing aluminum foam panel has in absorbing the sounds which strike the ceiling, the soundproof panels 600 for the construction of the ceiling, as shown in Figs. 14 to 17, have various patterns formed on their surfaces, so that they can be used as a construction finish material for the ceiling when they are optionally coated with a paint.

Abstract

L'invention concerne un panneau multi-usage insonorisé à base de mousse d'aluminium, qui est constitué d'au moins un panneau de mousse d'aluminium pourvu d'une pluralité de pores ouverts. Ces derniers sont formés à partir des pores fermés au sein d'une masse de mousse d'aluminium, la mousse d'aluminium étant roulée pour former un panneau. Ce panneau en mousse d'aluminium comportant une pluralité de pores ouverts est lié ou revêtu avec des fibrilles, une plaque fine perforée, un matériau de finition, une peinture, un élément insonorisant ou un isolant phonique ou encore une structure en nid d'abeilles sur au moins une surface, ou bien des motifs sont imprimés sur une surface, ou encore il est muni de cavités résonantes. En plus d'être utilisé comme matériau de finition de construction ultraléger, d'une grande longévité et d'une résistance élevée, dans les édifices ou les installations nécessitant une isolation phonique, ce panneau insonorisé présente des performances d'absorption acoustique supérieures et est facile à manipuler. Par ailleurs, ce panneau permet d'exécuter aisément des travaux de construction.
