Definitions
- the present invention relates to an insulation panel, specifically a sound-proofing and sound-insulating insulation panel, which is adaptable and capable of perfectly coupling to the surfaces to be mechanically dampened and acoustically insulated.
- such insulation panels have several disadvantages, as excessive weight, e.g. for the panels using lead foils, size, high cost, poor mechanical resistance, as e.g. for bituminous panels, the performance of which deteriorates as much with aging as because of exposure to low temperatures and/or temperature variations and which may easily dry and crack under the influence of vibrations and may also detach from their support. Even the most modern insulations obtained combining EPDM-based rubber layers as "mass" or panel base and polymer foams exhibit several disadvantages.
- the EPDM film may directly be produced in the mould by injection of liquid EPDM and subsequent cross-linking.
- the present invention intends to achieve the above discussed objects by obtaining a sound-insulating panel defining a distinctive extension plane and a distinctive thickness, wherein the plane has a greater extension as compared to thickness, which, according to claim 1, comprises a first layer in the direction of thickness made of a first non-expanded compact material and a second layer made of a second expanded material, wherein said first layer comprises one or more first areas having physical and/or size characteristics such that a higher sound absorption is obtained than by one or more second areas of the same first layer.
- the panel of the present invention exhibits a lower weight and size as compared to any panel of the known art having the same predetermined sound performances, by means of the differentiation in different areas of the first layer, or "mass" or base, of size characteristics, as thickness and surface extension, and/or of physical characteristics, as the density of the material.
- the panel of the invention has far better sound-proofing and sound-insulating characteristics.
- the differentiation of the "mass" of the panel is obtained by a simple spraying operation of the material forming the first layer, preferably polyurethane, on the surface of one of the two parts of the mould.
- a spraying operation is programmed depending on predetermined physical and/or size characteristics of the different areas of the first layer of the panel.
- the insulation panel object of the present invention, comprises a first layer 1 made of a compact polyurethane resin or any other equivalent material carrying a uniformly dispersed neutrally charged material, coupled to a second layer 2 made of an expanded viscoelastic polyurethane resin or any other equivalent material, the latter also carrying a uniformly dispersed neutrally charged material.
- Said second layer 2 of the insulation panel is preferably made of an expanded viscoelastic polyurethane resin prepared in a known way by reacting together (i) at least one compound selected from ethylene oxides and at least one compound selected from propylene oxides, named compound A, and (ii) one isocyanic compound, named compound B, an inert micronized compound, named compound C, being uniformly dispersed in said poly-urethane resin and being selected from glass fibres, artificial and natural textile fibres, silica, silicates, carbonates and the like, neat or mixed together.
- ethylene oxides and propylene oxides have molecular weight in the range from 300 to 8000, preferably from 350 to 6500, with a hydroxyl number in the range from 20 to 1000, preferably from 20 to 800, and functionality in the range from 3 to 8.
- Such compounds are used mixed together, according to what is known.
- the isocyanic compound is selected from the group comprising toluene diisocyanate, polymethylene-polyphenyl-isocyanates, diphenylisocyanates, having molecular weight in the range from 300 to 7500, preferably from 350 to 6000.
- the micronized material exhibits size in the range from 10 to 500 ⁇ m, preferably from 50 to 200 ⁇ m; in any case, possible particle size distribution is in the range from 10 to 50 ⁇ m, preferably from 10 to 30 ⁇ m.
- compound A is in a weight percentage in the range from 30 to 75%
- compound B is in a weight percentage in the range from 20 to 65%
- compound C is in a weight percentage in the range from 5 to 50%.
- Such second layer has a thickness in the range from 2 to 500 mm, preferably from 5 to 400 mm and a specific weight in the range from 30 to 200 Kg/m 3 , preferably from 30 to 150 Kg/m 3 .
- the material forming first layer 1 is a compact polyurethane resin instead, also prepared in a known way by reacting the same above-described compounds A, B, and C together.
- ethylene oxides and propylene oxides have molecular weight in the range from 300 to 8000, preferably from 350 to 6500, with a hydroxyl number in the range from 20 to 1000, preferably from 25 to 700, and functionality in the range from 3 to 8.
- Such compounds are used neat (only ethylene oxides or only propylene oxides) or mixed together, according to what is known.
- the isocyanic compound B has a molecular weight in the range from 350 and 7000, preferably from 400 to 6000.
- the micronized material has size in the range from 10 to 500 ⁇ m, preferably from 50 to 300 ⁇ m; in any case, possible particle size distribution is in the range from 10 to 50 ⁇ m and from 10 to 30 ⁇ m.
- compound A is in a weight percentage in the range from 30 to 75%
- compound B in a percentage in the range from 30 to 55%
- compound C in a percentage from 10 to 60 %.
- This first layer has a thickness in the range from 2 to 50 mm, and a basic weight in the range from 1 to 10 Kg/m 2 .
- said first layer 1 has an uneven thickness with first areas 3 having greater thickness as compared to that of second areas 4, in which said greater thickness defines higher sound absorption characteristics.
- the position, the thickness and the surface extension of first areas 3 is determined depending on the sound intensity peaks detected on the surface to coat with the panel, previously to the production of the panel.
- Second layer 2 comprises in turn distinctive first 4' and second 3' areas having thickness and/or surface extension complementary to those of corresponding second and first areas 4, 3 of first layer 1 of the panel, at the joining surface of the first and second layers.
- second layer 2 adhering to the first layer, has a constant thickness for the whole of its surface extension, as shown in Figure 2 .
- second layer 2 comprises distinctive first and second areas 4', 3' having thickness such that the total thickness of the panel is constant for the whole of its surface extension.
- a further advantageous embodiment of the panel of the invention provides instead that the higher sound absorption characteristics of first areas 3 as compared to second areas 4 of the first layer are defined by a different density of the material sprayed in these areas.
- first and second areas 3, 4 of first layer 1 of the panel may or may not have the same thickness.
- the last advantageous embodiment of the panel provides that the different sound absorption characteristics of the different areas of the first layer are defined by the combination of the different density of the material sprayed in these areas and of the different size characteristics, i.e. thickness and surface extension.
- the panel comprising said first and second layers, has an overall thickness in the range from 4 to 550 mm, preferably from 5 to 400 mm, and a specific weight in the range from 40 to 250 Kg/m 3 .
- the first and second layers of the panel, object of the present invention are directly coupled in the mould by means of a manufacturing process comprising the following steps:
- spraying is carried out in an open mould, preferably with an opening of about 90°, by means of an anthropomorphic robot controlling the displacement of the spray gun.
- a displacement and spraying is programmed depending on the intensity of the sound waves hitting the surface to be insulated. Therefore, the thickness and surface extension of the areas of first layer 1 of the panel may e.g. be differentiated by stopping the spray gun longer on the areas of the mould which correspond to the surface parts for which the sound intensity peaks are predicted to be higher, more or less wide, visible from a predetermined intensimetric mapping.
- the even thickness of the first layer is determined with reference to the highest intensity peak, resulting in an enormous waste of material and an increase of weight of the whole panel, generally having a basic weight of about 6 kg/m 2 .
- a second step follows, in which expanded polyurethane is injected in the mould, which is then closed.
- the expanded polyurethane resin further expands until it "grips" or adheres to said first layer, thus producing the second layer.
- the mould is opened and the end product is extracted.
- such a process for the manufacturing of the panels of the invention provides one step less as compared to the previously adopted processes and also provides the use of a simpler and less expensive technology.
- a preferred composition of the end panel comprises a layer of expanded viscoelastic polyurethane resin having density in the range from 30 to 150 Kg/m 3 , preferably 40-100 Kg/m 3 , containing the prescribed quantities of micronized material, in a weight percentage in the range from 10 to 50%, preferably from 15 to 45 %, and a layer of compact polyurethane resin having basic weight in the range from 1 to 10 Kg/m 2 , preferably from 2 to 8 Kg/m 2 , containing the prescribed amounts of micronized material in a weight percentage in the range from 10 to 50%, preferably from 20 to 50%.
- said panel has both sides provided with imprints having generally curved, preferably circular, oval or elliptic profile, and having maximum transverse size in the range from 5 to 15 mm, preferably from 7 to 13 mm, depth in the range from 1 to 10 mm, preferably from 2 to 6 mm, and distance between centres in the range from 1,10 to 1,80 times said maximum transverse size.
- the sides of the panel may take the most various shapes so as to conform to different surface configurations in order to acoustically isolate e.g. parts of a car body or engine compartments.
- the sides of the panel of the invention may therefore also have uneven surfaces and surfaces complementary to complex shape surfaces to be isolated.
- Panels comprising a second layer made of an expanded polyurethane material obtained by reacting a mixture comprised of 40% of a material named SPECFLEX NS 747 (manufactured by DOW CHEMICAL), 50% SPECFLEX Ns 540, 10% carbonate, having density equivalent to 50 Kg/m 3 , coupled to a first layer made of compact polyurethane material obtained by reacting a mixture comprised of 40% SPECFLEX Ns 768 (manufactured by DOW CHEMICAL), 20% SPECFLEX Ns 540, 40% carbonate, having basic weight equivalent to 5 Kg/m 2 , and thickness of respectively 20, 30, 45 mm, have been subjected to transmission loss sound-proofing experiments according to ASTM E1050-90 and ASTM C384-95.
- Panels comprising a second layer made of an expanded polyurethane material obtained by reacting a mixture comprised of 40% of a material named SPECFLEX Ns 747 (manufactured by DOW CHEMICAL), 50% SPECFLEX Ns 540, 10% carbonate having density of 50 Kg/m 3 , coupled to a first layer made of a compact polyurethane material obtained by reacting a mixture comprised of 40% SPECFLEX Ns 768, 20% SPECFLEX Ns 540, 40% Carbonate, having basic weight equivalent to 3 Kg/m 2 , and thickness of respectively 20, 30, 45 mm, have been subjected to transmission loss sound-proofing experiments according to ASTM E1050-90 and ASTM C384-95.
- differential mass panels according to the present invention exhibit higher sound-proofing performance as compared to those obtained with known panels.
- the difference experimentally found is considerable and is equivalent to about 2 ⁇ 4 dB at the different frequencies.
- the insulation panel of the invention Compared with an equal weight and size of other similar products, the insulation panel of the invention thus diminishes noise considerably better or, performance being equal, the panel exhibits a lighter weight.
