Description
'7800180-7 , *2 denna. Genom detta förfaringssätt kan man i en separat arbetsopera- tion bekläda bärplåten med ett sammanhängande skikt av ljudisolerma- terial, och bärplâten med ljudisolermaterialet monteras sedan på mo- torfordonschassits torped t ex genom popnitning, innan chassit täck- lackeras. '7800180-7, * 2 this. In this method, in a separate work operation, the support plate can be clad with a continuous layer of sound insulation material, and the support plate with the sound insulation material is then mounted on the motor vehicle chassis torpedo, for example by pop riveting, before the chassis is covered.
Vid en fördelaktig utföringsform av uppfinningen utformas ljud- isoleringsmaterialet såsom en skiktkonstruktion med ett väsentligen massivt delskikt närmst bärplåten och med ett värmeexpanderbart skikt närmst den vägg, som skall ljudisoleras. Om det tunga ljudisolerings- materialet bildas av en med tungt fyllmedel fylld bitumenmassa kan det värmeexpanderbara skiktet vid detta utföringsexempel lämpligen bildas av ett med bitumen impregnerat och därefter hoptryckt, elas- tiskt skumplastskikt. Detta elastiska skumplastskikt kvarhålles i sitt deformerade, hoptryckta tillstånd av det impregnerade bitumenet, tills hela skiktkonstruktionen upphettas till över bitumenets mjuk- ningspunkt. Vid denna upphettning kommer skumplastskiktet att för- söka återtaga sin odeformerade form, vilket medför att alla eventuel- la mellanrum mellan ljudisoleringsmaterialet och den vägg, som ljud- isoleras, kommer att utfyllas av det impregnerade skumplastskiktet.In an advantageous embodiment of the invention, the sound insulation material is designed as a layer construction with a substantially solid partial layer closest to the support plate and with a heat-expandable layer closest to the wall to be sound-insulated. If the heavy sound insulation material is formed by a bitumen mass filled with heavy filler, the heat-expandable layer in this exemplary embodiment can suitably be formed by a bitumen-impregnated and subsequently compressed, elastic foam layer. This elastic foam layer is retained in its deformed, compressed state by the impregnated bitumen until the entire layer structure is heated to above the softening point of the bitumen. During this heating, the foam plastic layer will try to regain its undeformed shape, which means that any gaps between the sound insulation material and the wall that is sound-insulated will be filled by the impregnated foam plastic layer.
Den ifrågavarande värmeaktiverade expansionen kan med fördel åstad- kommas i samband med bränningen av det täcklackerade fordonschassit.The heat-activated expansion in question can advantageously be achieved in connection with the firing of the top-coated vehicle chassis.
Såsom elastiskt skumplastskikt kan man använda ett öppna porer upp- visande polyesterskumskikt, som lamineras med resten av det ljud- isolerande bitumenskiktet.As the elastic foam plastic layer, an open pore having a polyester foam layer can be used, which is laminated with the rest of the sound-insulating bitumen layer.
I många fall önskar man icke någon fastlimning av ljudisole- ringsmaterialet mot den vägg, som skall ljudisoleras, eftersom man vid kollisionsskador i så fall skulle får svårigheter att reparera en deformerad mellanvägg mellan motorrummet och passagerarutrymmet.In many cases, it is not desired to glue the sound insulation material to the wall to be soundproofed, since in the event of collision damage it would be difficult to repair a deformed partition between the engine compartment and the passenger compartment.
I ett sådant fall är det enligt uppfinningen lämpligast att bekläda det ljudisolerande materialets mot väggen vända sida med ett sam- manklibbningsmotverkande materialskikt, t ex en polyetenfolie. Ett sådant sammanklibbningsmotverkande materialskikt kan användas både då ljudisoleringsmaterialet i helhet utgöres av ett väsentligen massivt material och då ljudisoleringsmaterialet utformas såsom en skiktkonstruktion med ett väsentligen massivt delskikt och med ett värmeexpanderbart ytterskikt.In such a case, according to the invention, it is most suitable to cover the sound-insulating material facing the wall with an anti-stick material layer, for example a polyethylene foil. Such an anti-stick material layer can be used both when the sound insulation material as a whole consists of a substantially solid material and when the sound insulation material is designed as a layer construction with a substantially solid partial layer and with a heat-expandable outer layer.
Vid ett utföringsexempel på uppfinningen skulle torpedväggen mellan motorrummet och passagerarutrymmet i ett motorfordon beklä- >das med ett ljudisolerande bitumenskikt. Torpedväggen hade en tjock- lek av ca 1,2 mm. En bärplât formpressades av ett 0,6 mm plâtma- 3 É 7800180-7 terial och gavs härvid en form, som väsentligen anslöt sig till torpedväggens form. På den sida av bärplåten, som skulle vändas mot torpedväggen, förankrades ett bitumenskikt, som hade en tjock- lek av ca 5 mm. Förankringen utfördes genom att bitumenskiktet be- lades med ett limskikt på sin mot bärplåten vända sida och genom att bitumenskiktet och bärplåten upphettades, så att bitumenskiktet mjuknade och genom sin egen tyngd kom att sjunka ned mot den på ett horisontellt underlag placerade bärplâten. Alternativt kan bitumen- skiktet förvärmas och sedan pressas till anliggning mot bärplåten.In an embodiment of the invention, the torpedo wall between the engine compartment and the passenger compartment of a motor vehicle would be clad with a sound-insulating bitumen layer. The torpedo wall had a thickness of about 1.2 mm. A support plate was compression molded from a 0.6 mm plate material to give a mold which substantially adhered to the shape of the torpedo wall. On the side of the support plate, which was to face the torpedo wall, a bitumen layer was anchored, which had a thickness of about 5 mm. The anchoring was performed by coating the bitumen layer with an adhesive layer on its side facing the support plate and by heating the bitumen layer and the support plate so that the bitumen layer softened and by its own weight came to sink down towards the support plate placed on a horizontal surface. Alternatively, the bitumen layer can be preheated and then pressed to abut against the support plate.
Bärplåten med fastsittande bitumenskikt monterades sedan på det ifrå- gavarande motorfordonets torpedvägg genom popnitning, innan fordons- chassit täcklackerats. Efter täcklackeringen upphettades fordons- chassit pâ sedvanligt sätt i en ung, varvid det mot torpedväggen vända bitumenskiktet brändes fast vid torpedväggen. Samma tillväga- gångssätt kan utnyttjas i det fall att man icke önskar någon fast- klibbning av bitumenskiktet mot den vägg, som skall ljudisoleras. I detta fall får emellertid bitumenskiktet beläggas med ett samman- klibbningsmotverkande materialskikt på sin mot mellanväggen vända sida.The support plate with attached bitumen layer was then mounted on the torpedo wall of the motor vehicle in question by pop riveting, before the vehicle chassis was covered with paint. After the topcoat was applied, the vehicle chassis was heated in the usual manner in a young, whereby the bitumen layer facing the torpedo wall was burned to the torpedo wall. The same approach can be used in the event that no bitumen layer is desired to be adhered to the wall to be soundproofed. In this case, however, the bitumen layer may be coated with an anti-stick material layer on its side facing the partition wall.
Om man däremot önskar att alla mellanrum mellan bärplåten och torpedväggen utfylles av ljudisoleringsmaterial och om man sålunda väljer den utföringsform av uppfinningen, där ljudisoleringsmateria- let utformas med ett expanderbart ytterskikt, anbringas det av ett laminat bestående bitumenskiktet på bärplåten på ovan angivet sätt, varefter bärplåten med påsittande ljudisoleringsmaterial placeras i en press, i vilken det bitumenimpregnerade skumplastskiktet sam- mantryckes till en deformerad hoptryckt form. Efter transport till monteringsstället och montering på motorfordonets torpedvägg, kom- mer det deformerade skumplastskiktet att expandera vid fordonschas- sits upphettning i samband med täcklackeringen. Även i detta fall kan ljudisoleringsmaterialets mot torpedväggen vända sida ha be- klätts med ett sammanklibbningsmotverkande materialskikt, om man så önskar.If, on the other hand, it is desired that all gaps between the support plate and the torpedo wall be filled with sound insulation material and if one thus chooses the embodiment of the invention where the sound insulation material is formed with an expandable outer layer, it is applied to the support plate. with attached sound insulation material is placed in a press, in which the bitumen-impregnated foam plastic layer is compressed into a deformed compressed mold. After transport to the mounting location and mounting on the motor vehicle's torpedo wall, the deformed foam layer will expand when the vehicle chassis seat is heated in connection with the topcoat. Also in this case, the side of the sound insulation material facing the torpedo wall may have been covered with a layer of anti-sticking material, if desired.
