Description
Predložený vynález sa týka panelu so zvukovou izoláciou, najmä tvrdého podlahového panelu, najmä na laminátovú podlahu.The present invention relates to a panel with acoustic insulation, in particular a hard floor panel, in particular for a laminate floor.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Známe je, že sa nepriaznivé zvukové vlastnosti laminátových podláh zlepšujú tým spôsobom, že sa ukladajú špeciálne podložky medzi laminátovú podlahu a spodnú konštrukciu (napríklad poter). Tým sa má na jednej strane zlepšiť kročajový hluk - odovzdávanie hluku poteru - a hluk v miestnosti - spätné vyžarovanie zvukovej energie do priestoru, ktorý sa nachádza nad podlahou. Nepriaznivé vlastnosti laminátových podlahových panelov vznikajú následkom vysokej hustoty a vláknitého materiálu s vysokou hustotou alebo vláknitého materiálu so strednou hustotou (doska vláknitého materiálu s vysokou hustotou (HDF), alebo doska vláknitého materiálu so strednou hustotou (MD F)).It is known that the unfavorable sound properties of laminate floors are improved by placing special pads between the laminate floor and the substructure (e.g. screed). On the one hand, this is to improve the footfall noise - the transmission of screed noise - and the noise in the room - the back emission of sound energy to the space above the floor. The unfavorable properties of laminate floor panels arise from high density and high density fibrous material or medium density fibrous material (high density fibrous material board (HDF) or medium density fibrous material board (MD F)).
Spravidla je potrebné na zvukovú izoláciu vopred určiť rozličné podložky vzhľadom na ich hustotu a na ich vlastnosti. Tieto podložky sú vyrábané oddeleným výrobným postupom a potom sú alebo v priebehu ukladania podlahy voľne ukladané pod podlahu, alebo sú s ňou na mieste montáže zlepené, aby sa dosiahli ďalšie zlepšenia. Zo stavu techniky je takisto známe, že sa podložky zlepia s podlahovými panelmi v priebehu výroby týchto podlahových panelov, čím sa dosiahne ľahšie ukladanie podlahy.As a rule, it is necessary to predetermine different substrates for sound insulation in terms of their density and their properties. These pads are manufactured by a separate manufacturing process and are then laid loosely under the floor or during the laying of the floor or glued with it at the assembly site to achieve further improvements. It is also known in the art that pads are bonded to floor panels during the manufacture of such floor panels, thereby providing easier laying of the floor.
Z dokumentu DE 201 08 668 U1 je známy laminátový podlahový panel, ktorý je na zadnej strane vybavený materiálom na zvukovú izoláciu, pričom do materiálu môžu byť vnesené plnivá, ktorých hustota sa nachádza pod tou hustotou, ktorú má materiál zvukovej izolácie. Materiál zvukovej izolácie je pritom nanášaný v kvapalnom stave.From DE 201 08 668 U1, a laminate floor panel is known which is provided on the back with a sound-insulating material, and fillers having a density below the density of the sound-insulating material can be introduced into the material. The sound insulation material is applied in the liquid state.
Podstata vynálezuSUMMARY OF THE INVENTION
Vychádzajúc z toho rieši predložený vynález technický problém tak, že predkladá spôsob výroby panelu, ako aj samotný panel, ktorý máoproti súčasnému stavu techniky zlepšené vlastnosti zvukovej techniky.Accordingly, the present invention solves the technical problem by presenting a method of manufacturing the panel as well as the panel itself, which has improved audio technology characteristics compared to the prior art.
Predtým uvedený technický problém j e podľa vynálezu riešený spôsobom podľa nároku 1. Ďalšie výhodné rozšírenie tohto spôsobuje uvedené v závislých nárokoch.The foregoing technical problem according to the invention is solved by the method according to claim 1. A further advantageous extension of this method is stated in the dependent claims.
Vynález sa preto týka spôsobu na výrobu panelu so zvukovou izoláciou, najmä laminátového podlahového panelu, pri ktorom sa v prvej operácii vyrobí panel a v druhej operácii sa zhotoví zvuková izolácia nanesením najmenej jedného kvapalného materiálu na spodnú stranu panelu, a pri ktorom sú s materiálom nanesenej zvukovej izolácie spájané plnivá, ktorých hustota je vyššia ako hustota ako hustota materiálu zvukovej izolácie, pričom sa materiál zvukovej izolácie spojí so spodnou stranou panelu pomocou aspoň čiastočného vytvrdenia.The invention therefore relates to a method for producing a sound insulating panel, in particular a laminate floor panel, in which a panel is manufactured in a first operation and a sound insulation is produced by applying at least one liquid material to the underside of the panel in a second operation. fillers having a density greater than that of the sound insulation material, the sound insulation material being bonded to the underside of the panel by at least partially curing.
Vynález sa vyznačuje tým, že zvukoizolačná vrstva nie je pred spojením so spodnou stranou panelu samostatnou podložkou, ale sa len v priebehu výroby vytvorí na zadnej strane panelu. Takto odpadne jedna výrobná operácia, čím sa zlacnie a zjednoduší výroba.The invention is characterized in that the soundproofing layer is not a separate backing prior to joining with the underside of the panel, but is only formed on the back of the panel during manufacture. This eliminates the need for a single manufacturing operation, making production less expensive and simpler.
Rovnako sa rieši uvedený technický problém panelom so zvukovou izoláciou podľa znakov nároku 13, pričom aj v tomto prípade je v závislých nárokoch uvedené výhodné rozšírenie riešenia panelu.Similarly, said technical problem is solved by a sound-insulated panel according to the features of claim 13, and in this case too, the advantageous extension of the panel solution is mentioned in the dependent claims.
Na to sa na hotovú zadnú stranu podlahového panelu nanáša kvapalný alebo skvapalniteľný materiál. Toto sa môže uskutočniť celoplošne, v tvare pásov alebo v tvare siete.To this end, a liquid or liquid material is applied to the finished back of the floor panel. This can be done across the board, in the form of strips or in the form of a mesh.
Prehľad obrázkov na výkreseOverview of the figures in the drawing
Nasledovne sa vynález bližšie vysvetlí pomocou príkladov uskutočnenia, pričom sa odvolávame na priložený výkres. Na výkrese obr. 1 je schematické trojrozmerné znázornenie dvoch panelov s rozlične nanesenou zvukovou izoláciou; a obr. 2 znázorňuje v reze rozličné príklady usporiadania zvukovej izolácie.In the following, the invention will be explained in more detail with reference to the accompanying drawing. In the drawing, FIG. 1 is a schematic three-dimensional representation of two panels with differently applied sound insulation; and FIG. 2 shows various examples of a sound insulation arrangement.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Obr. 1 znázorňuje rozličné príklady uskutočnenia panelov so zvukovou izoláciou, ktorá bola vyhotovená spôsobom podľa vynálezu.Fig. 1 shows various embodiments of panels with sound insulation made according to the method of the invention.
Panel pozostáva hlavne z vrstvy materiálu 20, ktorá môže byť vytvorená aj ako vrstvená a ktorá môže obsahovať laminátové vrstvy. Na obrázku 1 smerom nadol orientovaná vrchná strana 1 panelu zodpovedá vidiThe panel consists mainly of a layer of material 20, which may also be formed as a laminate and which may comprise laminate layers. In FIG. 1, the downward facing side 1 of the panel corresponds to the view
SK 286816 Β6 teľnej strane panelu pri jeho použití, na obrázku 1 smerom nahor orientovaná spodná strana 2 nesie zvukovú izoláciu. Táto môže byť alebo celoplošným nánosom 3, alebo nánosom v pásoch 4 a 5, pričom pri nánose 5 nie sú jednotlivé pásy, prípadne povrazce materiálu priebežné. Nános v tvare siete môže byť nanesený vzhľadom na vonkajšiu hranu panelu diagonálne - pozri vzťahovú značku 6, paralelne - pozri vzťahovú značku 7, alebo zmiešané - pozri vzťahovú značku 8.SK 286816 Β6 the upper side of the panel in use, the upwardly facing bottom 2 of Figure 1 carries sound insulation. This can be a full-area coating 3 or a coating in strips 4 and 5, whereby the individual strips or strands of material are not continuous in the case of the coating 5. The grid-shaped coating may be applied diagonally with respect to the outer edge of the panel - see reference numeral 6, in parallel - see reference numeral 7, or mixed - see reference numeral 8.
Vzdialenosti - rozstupy jednotlivých nánosov pri vyhotovení v tvare pásov alebo v tvare siete môžu byť zosúladené s vibračnými uzlami, aby sa dosiahlo zvukové optimum v určitých oblastiach vlnových dĺžok. Pritom možno vychádzať napríklad z oblasti zvukovej frekvencie približne 1,0 až 4 kHz a rýchlosti zvuku v materiáli panelu približne 0,5 až 3,5 km/sekundu. Rozmery štruktúry siete sú potom prispôsobené dĺžkam základnej vlny v rozsahu metrov alebo desiatok centimetrov, aby sa dosiahla čo možno najlepšia zvuková izolácia. Pritom možno zvoliť aj na jednotlivých miestach plochy sa meniaci rozstup siete.Distances - The spacing of individual coatings in strip or mesh design can be matched to the vibrating knots to achieve sound optimum in certain wavelength regions. For example, a sound frequency range of approximately 1.0 to 4 kHz and a sound velocity in the panel material of approximately 0.5 to 3.5 km / second may be used. The dimensions of the network structure are then adjusted to the base wave lengths in the range of meters or tens of centimeters to obtain the best possible sound insulation. The varying grid spacing can also be selected at individual locations on the surface.
Skvapalniteľným materiálom môže byť napríklad tavné lepidlo (na báze polyvinylacetátu alebo reaktívne tavné lepidlo na báze polyuretánu), vhodné sú však aj kvapalné materiály ako elastoméry, najmä dvojzložkové elastoméry (ako napríklad polyuretány). Uvedené materiály rýchlo vytvrdnú pri nasledujúcom ochladení a takto sa spájajú s povrchom spodnej strany panelu.For example, the liquid material may be a hot melt adhesive (based on polyvinyl acetate or a reactive hot melt based on polyurethane), but liquid materials such as elastomers, in particular two-component elastomers (such as polyurethanes), are also suitable. Said materials rapidly cure upon subsequent cooling and thus bond to the surface of the underside of the panel.
Aby sa zlepšili zvukové technické vlastnosti, existuje možnosť zakomponovať plnivá vysokej hustoty. Na to sa hodia minerálne plnivá (baryt, kremenný piesok, oxid titánu) a kovové plnivá (železo, hliník). Plnivá môžu byť nanášané v priebehu výroby ako osobitná vrstva. S týmto cieľom sa nasypú na skvapalnenú hmotu a pri vytvrdení tohto materiálu sa s ním spoja.In order to improve the sound technical properties, there is the possibility of incorporating high density fillers. Mineral fillers (barite, quartz sand, titanium oxide) and metal fillers (iron, aluminum) are suitable for this purpose. The fillers may be applied as a separate layer during manufacture. To this end, they are poured onto the liquefied material and bonded to it when the material cures.
Ďalšou možnosťou je, že sa materiál už pred nanášaním na panel zmieša s plnivami, čím sa dosiahne homogénna zmes plniva a materiálu.Alternatively, the material may be mixed with fillers prior to application to the panel to provide a homogeneous mixture of filler and material.
Taktiež je mysliteľné, že sa aplikujú viaceré rozličné vrstvy materiálu, ako napríklad materiály s rozličnými typmi plnív.It is also conceivable that several different layers of material, such as materials with different types of filler, are applied.
Okrem toho možno nanášať vrstvu v tvare pásu na ešte kvapalnú masu. Môže to byť napríklad fólia na parotesné izolovanie (polyetylénová fólia, hliníková fólia), podložka proti kročajovému hluku (extrudovaný polyetylén, mäkká PVC - fólia), alebo aj kartón.In addition, a strip-shaped layer can be applied to the still liquid meat. It can be, for example, a vapor barrier film (polyethylene film, aluminum foil), impact sound insulation (extruded polyethylene, soft PVC film), or even cardboard.
Obrázok 2 znázorňuje rezy panelov vždy s vrstvou materiálu 20 a s ňou spojenou zvukovou izoláciu rôzneho uskutočnenia.Figure 2 shows sections of panels each with a layer of material 20 and associated sound insulation of various embodiments.
Na obrázku 2a je materiál v tvare pásov a bez prídavných plnív.In Figure 2a, the material is in the form of strips and without additional fillers.
Na obrázku 2b je celoplošný nános materiálu 11, v ktorom sú dispergované plnivá 12. Plnivá 12 sú v tomto prípade znázornené bodkami.In Figure 2b, there is a full-surface deposition of material 11 in which fillers 12 are dispersed. In this case, the fillers 12 are shown by dots.
Na obrázku 2c pozostáva zvuková izolácia z homogénneho materiálu 13, na ktorom sú povrchovo aplikované plnivá 14 ako separátna vrstva. Plnivá 14 sú schematicky znázornené bodkami.In Figure 2c, the sound insulation consists of a homogeneous material 13 on which the fillers 14 are applied as a separate layer. The fillers 14 are schematically represented by dots.
Obrázok 2d znázorňuje kombináciu dvoch vrstiev materiálov, pričom prvá vrstva pozostáva zo zmesi materiálu 11 a plniva 12, a druhá vrstva z materiálu bez plniva 12, táto je nanesená v tvare pásov.Figure 2d shows a combination of two layers of materials, the first layer consisting of a mixture of material 11 and filler 12, and a second layer of non-filler material 12, which is applied in the form of strips.
Obrázok 2e taktiež znázorňuje viacvrstvové uskutočnenie pozostávajúce z prvej vrstvy ako v príklade 2d, zo separátnej vrstvy plniva 15, ktorá je tu znázornená šikmými čiarami a z uzatváracej vrstvy 16, ktorá nemá žiadne plnivá.Figure 2e also depicts a multilayered embodiment consisting of a first layer as in Example 2d, a separate filler layer 15 shown here in bevel lines, and a sealing layer 16 having no fillers.
Príklad 2f znázorňuje fóliu 17, nanesenú na zvukovú izoláciu 10, pričom fólia môže mať tiež zvukoizolačné vlastnosti.Example 2f illustrates a film 17 applied to the soundproofing 10, wherein the film may also have sound insulation properties.
