Doterajší stav technikyBACKGROUND OF THE INVENTION
Pri výrobe vozidiel, strojov a prístrojov sa dnes prakticky výlučne používajú veľmi tenkostenné plechy. Mechanicky sa pohybujúce diely alebo bežiace motory uvádzajú tieto tenkostenné plechy nevyhnutne do chvenia, ktoré je často v oblasti počuteľnosti ľudským uchom. Tieto kmity sa vo forme zvuku v tuhej látke šíria ďalej cez celé vozidlo, resp. stroj alebo prístroj, a na vzdialených miestach sa môžu vyžiariť do vzduchu ako rušivý hluk. Na zníženie vyžarovania hluku a na tlmenie zvuku v tuhej látke sa preto tieto plechy, najmä pri výrobe automobilov a pri výrobe domácich spotrebičov, vybavujú povrchovými vrstvami na tlmenie hluku, tzv. antivibračnými povlakmi.Today, very thin-walled sheets are used almost exclusively in the manufacture of vehicles, machinery and equipment. Mechanically moving parts or running engines introduce these thin-walled sheets inevitably, which is often in the area of audibility by the human ear. In the form of sound in the solid, these oscillations spread further throughout the vehicle or vehicle. machine or apparatus, and may be emitted in the air as disturbing noise in distant locations. Therefore, in order to reduce the emission of noise and to dampen sound in solids, these sheets, in particular in the manufacture of automobiles and in the manufacture of household appliances, are provided with noise-damping coatings. anti-vibration coatings.
Podľa bežného spôsobu sa pritom pretláčajú zmesi plnív s vysokou hustotou a bitúmenu na fólie, z ktorých sa potom vyrážajú alebo vyrezávajú zodpovedajúce tvarované diely. Potom sa tieto fólie nalepia na príslušné plechové diely, pričom sa prípadne musia za zahrievania prispôsobiť tvaru plechu. Hoci sa tieto bitúmenové fólie z dôvodu ich nízkej materiálovej ceny ešte často používajú, sú veľmi krehké a najmä pri nízkych teplotách majú tendenciu odlupovať sa od plechu. Aj často navrhované prísady elastomérov poskytujú len malé zlepšenie, ktoré pre mnohé použitia nie je dostatočné. Okrem toho nanášanie predtvarovaných bitúmenových dielov na zložito tvarované alebo ťažko prístupné plechové diely strojov alebo vozidiel, napr. na vnútorné plochy dutých priestorov dverí motorových vozidiel, nie je vôbec možné. Ako ďalšia nevýhoda sa k tomu pridružuje, že pre jediné vozidlo alebo prístroj sú v mnohých prípadoch potrebné viaceré vyrazené diely, v dôsledku čoho je potrebné ich nákladné skladovanie.According to a conventional method, high density filler and bitumen mixtures are extruded onto films, from which the corresponding molded parts are then punched or cut. Thereafter, these films are adhered to the respective sheet metal parts and, if necessary, have to be adapted to the shape of the sheet under heating. Although these bitumen films are still frequently used because of their low material cost, they are very fragile and tend to peel off from the sheet, especially at low temperatures. Even the frequently proposed elastomer additions provide little improvement, which is not sufficient for many applications. In addition, the application of preformed bitumen parts to difficult-to-form or difficult-to-access sheet metal parts of machines or vehicles, e.g. on the inner surfaces of the hollow spaces of motor vehicle doors is not possible at all. As a further disadvantage, in addition, a number of embossed parts are required for a single vehicle or apparatus in many cases, requiring costly storage.
Preto sa uskutočňovali pokusy vylúčiť nevýhody bitúmenových fólií inými systémami polymérov. Tak sa napr. vyvinuli vodné polymérne disperzie polyvinylacetátových alebo etylén-vinylacetátových kopolymérov, obsahujúce plnivá, ktoré sa na plechové diely dajú nastriekať s potrebnou hrúbkou vrstvy. Tieto systémy sú však na priemyselné použitie pri vysokom počte zhotovovaných kusov nevýhodné, pretože najmä pri veľkých hrúbkach vrstvy sa voda z nastriekanej vrstvy nedá odstrániť dostatočne rýchlo. Ďalšia nevýhoda týchto bežných metód tlmenia hluku spočíva v tom, že tieto materiály slúžia na jediný účel, na tlmenie hluku.Therefore, attempts have been made to eliminate the disadvantages of bituminous films by other polymer systems. Thus, e.g. have developed aqueous polymer dispersions of polyvinyl acetate or ethylene-vinyl acetate copolymers containing fillers which can be sprayed onto the sheet metal parts with the required layer thickness. However, these systems are disadvantageous for industrial use with a high number of pieces to be manufactured, since, particularly at high layer thicknesses, water cannot be removed from the sprayed layer sufficiently quickly. A further disadvantage of these conventional noise attenuation methods is that these materials serve the sole purpose of attenuating noise.
Pri výrobe vozidiel, strojov a prístrojov sa dnes vyvíja úsilie zjednodušiť zložitosť výrobných procesov a tým znížiť výrobné náklady.In the manufacture of vehicles, machinery and equipment, efforts are now being made to simplify the complexity of production processes and thereby reduce production costs.
Pri výrobe vozidiel, strojov a prístrojov sa ďalej používajú lepidlá, tesniace materiály a ochranné vrstvy. Doteraz sa lepidlá a/alebo tesniace materiály volili najmä na základe ich primárnych vlastností:In addition, adhesives, sealants and protective coatings are used in the manufacture of vehicles, machinery and equipment. To date, adhesives and / or sealants have been selected mainly on the basis of their primary properties:
- pevnosť, t.j. pevnosť v strihu, odolnosť proti odlupovaniu- strength, i. shear strength, peel resistance
- pretiahnutie pri pretrhnutí, ohybnosť- elongation at break, flexibility
- odolnosť proti starnutiu- resistance to aging
- jednoduchá manipulácia.- easy handling.
Pri ochranných vrstvách, špeciálne pri ochranných vrstvách na spodku je odolnosť proti oderu ďalším kritériom voľby.Abrasion resistance is another criterion of choice for protective coatings, especially for protective coatings at the bottom.
Vyvíja sa mnoho úsilia zmenšiť zložitosť výroby vozidiel, strojov a prístrojov a tým znížiť výrobné náklady.Many efforts are being made to reduce the complexity of manufacturing vehicles, machinery and equipment, thereby reducing production costs.
Preto existuje potreba multifunkčných produktov, t.j. napr. existuje potreba lepidiel, tesniacich materiálov a/alebo ochranných vrstiev, ktoré popri svojej hlavnej funkcii riešia ďalšie problémy.Therefore, there is a need for multifunctional products, i. e.g. there is a need for adhesives, sealants and / or protective layers which, in addition to their main function, solve other problems.
EP-A-358598 alebo DE-A-3444863 opisujú plastisólové formulácie, ktoré plnia dvojitú funkciu ochrany spodku (ochrana proti oderu) a akustického tlmenia. DE-A-4013318 opisuje dvojvrstvovú ochranu spodku, ktorá plní funkcie ochrany spodku a pohlcovania hluku, ktorý pochádza od narážajúcich častíc (kameňov, štrku, vody, atď.). Zatiaľ čo tieto výrobky/spôsoby celkom uspokojivo spĺňajú kombináciu ochrany spodku a tlmenia hluku, existuje hlavne potreba kombinovať funkciu lepidla a/alebo tesniaceho materiálu s tlmením hluku. To je predovšetkým žiaduce pre tie diely automobilu, stroja alebo prístroja, ktoré nepotrebujú žiadnu ochranu proti oderu, ako napr. kryt batožinového priestoru, kapota motora, dvere alebo čelná stena vozidla.EP-A-358598 or DE-A-3444863 disclose plastisol formulations which fulfill the dual function of underbody protection (abrasion protection) and acoustic damping. DE-A-4013318 discloses a two-layer bottom protection which fulfills the functions of bottom protection and noise absorption from impacting particles (stones, gravel, water, etc.). While these products / processes satisfactorily satisfy the combination of bottom protection and sound attenuation, there is a particular need to combine the function of adhesive and / or sealant with noise attenuation. This is particularly desirable for those parts of a car, machine or apparatus that do not need any abrasion protection, such as e.g. the luggage compartment cover, the bonnet, the door or the front of the vehicle.
Lepiace a tesniace materiály pre tieto diely sa normálne použijú y procese výroby skoro, v takzvanej hrubej montáži . Pri tom použité plechy sú pokryté olejmi na ochranu proti korózii a olejmi na ťahanie v množstve viac gramov na m , takže použitý lepiaci/tesniaci materiál musí mať schopnosť tieto oleje absorbovať. Hoci sa v hrubej montáži používajú plastisóly, najmä PVC-plastisóly, tie plastisóly, ktoré sa uvádzajú v EP-A-358598 alebo v DE-A-3444863, nie sú vhodné ako lepiace/tesniace materiály pre hrubú montáž. Plastisólové formulácie, ktoré sa vyvinuli špeciálne pre hrubú montá, nemajú žiadne alebo takmer žiadne zvukovoizolačné vlastnosti.Adhesive and sealant materials for these parts are normally used in the manufacturing process early in the so-called rough assembly. The sheets used are coated with corrosion protection oils and drawing oils in an amount of more grams per m, so that the adhesive / sealing material used must have the ability to absorb these oils. Although plastisols, especially PVC plastisols, are used in rough assembly, those plastisols disclosed in EP-A-358598 or DE-A-3444863 are not suitable as adhesive / sealant materials for rough assembly. Plastisol formulations that have been developed specifically for rough assembly have no or almost no sound insulation properties.
Ďalšia skupina lepiacich/tesniacich materiálov, ktoré sú vhodné na použitie v hrubej montáži, je na báze kaučukov, najmä vulkanizovateľných zmesí na báze 1,4-polybutadiénov a/alebo 1,4-polyizoprénov. Tieto zmesi obsahujú s výhodou tekuté polydiény s nízkou molekulovou hmotnosťou, síru a prípadne urýchľovače pre vulkanizáciu sírou. Naviac môžu tieto zmesi obsahovať vysokomolekulový, tzv. tuhý kaučuk, pričom tekuté polydiény a/alebo tuhý kaučuk môžu obsahovať funkčné skupiny, ako napríklad hydroxylové skupiny, karboxylové skupiny, anhydridové skupiny alebo epoxyskupiny. Táto skupina lepiacich/tesniacich materiálov na báze kaučuku je opísaná v rade patentových prihlášok, napr. EP-A-97394, EP-A-309903, EP-A-309904, DE-A-3834818, DE-A-4120502, DE-A-4122849 , ÉP-A-181441 a EP-A.-356715 .Another group of adhesive / sealant materials suitable for use in rough assembly is rubber based, in particular vulcanizable mixtures based on 1,4-polybutadiene and / or 1,4-polyisoprene. These compositions preferably comprise low molecular weight liquid polydienes, sulfur and optionally accelerators for sulfur vulcanization. In addition, these compositions may contain high molecular weight, so-called " the solid rubber, wherein the liquid polydienes and / or the solid rubber may contain functional groups such as hydroxyl groups, carboxyl groups, anhydride groups or epoxy groups. This group of rubber-based adhesive / sealing materials is described in a number of patent applications, e.g. EP-A-97394, EP-A-309903, DE-A-309904, DE-A-3834818, DE-A-4120502, DE-A-4122849, EP-A-181441 and EP-A-356715.
V DE-A-4122849 sa uvádza, že zlepenie plechov pri hrubej montáži automobilov má o.i. za cieľ tlmiť vznikajúce kmity. Tento spis síce k tomu neuvádza žiadne bližšie údaje, ale dá sa vychádzať z toho, že u týchto kmitov ide o nízkofrekvenčné kmity mimo oblasti počuteľnosti ľudským uchom, ktoré vznikajú napr. pri vibráciách motorových kapôt, krytov batožinových priestorov a dverí, keď tieto nemajú vhodné zosilňovacie rámy (antiflutter adhesive).DE-A-4122849 discloses that the bonding of sheets for rough assembly of cars has an o.i. aim to dampen emerging oscillations. Although this document does not provide any further details, it can be assumed that these oscillations are low-frequency oscillations outside the area of audibility to the human ear, e.g. in the case of vibration of bonnets, boot covers and doors when they do not have suitable antiflutter adhesive frames.
EP-A-181441 opisuje dvojzložkové, za tepla zosieťovateľné hmoty a spôsob výroby za studená sieťujúcich hmôt, pričom jedno spojivo obsahuje hydroxylové skupiny a druhé spojivo obsahuje karboxylové skupiny resp. anhydridové skupiny kyselín. Bezprostredne pri použití sá tu musia obe zložky zmiešať, vytvrdnutie sa uskutoční buď za tepla za tvorby esterov medzi hydroxylovými skupinami a skupinami karboxylových kyselín, alebo vytvrdnutie za studená vyžaduje pridanie katalyzátorov. Udáva sa, že tieto hmoty možno použiť o.i. ako kmity tlmiace alebo hluk tlmiace hmoty. Ďalšie údaje, najmä k účinnosti tohto tlmenia, resp. ktoré substráty sa majú tlmiť, v tomto spise chýbajú.EP-A-181441 discloses two-component thermally crosslinkable compositions and a process for producing cold crosslinking compositions, wherein one binder contains hydroxyl groups and the other binder contains carboxyl groups, respectively. acid anhydride groups. Immediately when using the sieve, the two components must be mixed together, either by hot curing to form esters between hydroxyl groups and carboxylic acid groups, or by cold curing requiring the addition of catalysts. It is stated that these compositions can be used o.i. as vibration damping or noise damping materials. Further data, in particular on the effectiveness of this damping, respectively. which substrates are to be damped are missing in this specification.
Ešte nezverejnená európska prihláška 93120384.8 opisuje použitie 3,4-polyizoprénu v kombináci s ďalšími vytvrditelnými alebo nevytvrditelnými, tekutými a/alebo tuhými kaučukmi a použitie týchto zmesí na jednozložkové, za horúca vulkanizovateľné lepiace/tesniace materiály s akustickými tlmivými vlastnosťami.Not yet published European application 93120384.8 discloses the use of 3,4-polyisoprene in combination with other curable or non-curable, liquid and / or solid rubbers, and the use of these mixtures for mono-component, hot-vulcanizable adhesive / sealant materials with acoustic damping properties.
Podstata vynálezuSUMMARY OF THE INVENTION
Zistilo sa teraz, že jednozložkové, za horúca vulkanizovateľné lepiace/tesniace materiály na báze tekutých kauču kov a prípadne tuhých kaučukov sa dajú modifikovať tak, že použitie ťažko dostupného 3,4-polyizoprénu nie je potrebné, pričom sa napriek tomu u týchto zmesí dosahuje veľmi dobré akustické tlmenie.It has now been found that mono-component, hot-vulcanizable adhesive / sealant materials based on liquid metal rubbers and possibly solid rubbers can be modified such that the use of the hardly available 3,4-polyisoprene is unnecessary, yet very high levels of these mixtures are achieved. good acoustic attenuation.
Pod akusticky účinným tlmením alebo tlmením kmitov sa v zmysle tohto vynálezu má rozumieť tlmenie zvuku v tuhej látke, ktoré, ako je známe, spôsobuje zníženie hučania plechových konštrukcií.For the purposes of the present invention, acoustically effective or vibration damping is to be understood as damping sound in a solid, which, as is known, causes a reduction in the humming of sheet metal structures.
Posúdenie účinnosti akustických tlmivých vlastností zmesí podľa tohto vynálezu sa pritom uskutočňuje podľa pokusu s kmitavým namáhaním ohybom podľa Časti 3 DIN 53440. Na to sa na oceľové plechy nanesú vrstvy zmesí podľa tohto vynálezu, tieto vrstvy sa potom za teplotných podmienok, aké napr. prevládajú pri výrobe vozidiel na vytvrdenie rôznych lakových systémov, t.j. v oblastí medzi 130 °C a 220 °C, vytvrdia. Pokus s kmitavým namáhaním ohybom sa potom uskutoční pri 200 Hz a rôznych teplotách,·aby sa dalo posúdiť účinné akustické tlmivé pôsobenie týchto zmesi v oblasti teplôt použitia, t.j. medzi asi 0 °C a +40 °C. Akusticky účinnými v zmysle tohto vynálezu by mali byť všetky za horúca vytvrditeľné (vulkanizovateľné) zmesi, ktoré v pokuse s kmitavým namáhaním ohybom podľa DIN 53440, Časť 3, vykazujú extrémne vysoké tlmenie, t.j. stratový činiteľ plechového pásika s nanesenou vrstvou d(combi) >0,1, s výhodou 0,2 alebo viac.The performance evaluation of the acoustic damping properties of the compositions according to the invention is carried out in accordance with the oscillating bending test according to Part 3 of DIN 53440. they predominate in the manufacture of vehicles for the curing of various paint systems, i.e. in the range between 130 ° C and 220 ° C, they cure. The oscillating bending experiment is then carried out at 200 Hz and at different temperatures, in order to assess the effective acoustic buffering effect of these mixtures in the temperature range of use, i. between about 0 ° C and +40 ° C. Acoustically effective for the purposes of the present invention should be all hot-curable (vulcanizable) compositions which exhibit extremely high damping, i.e., high-damping properties in a bending experiment according to DIN 53440, Part 3. a sheet metal loss factor with a d (combi) coating of > 0.1, preferably 0.2 or more.

Príkladmi takýchto funkčných skupín sú hydroxylové skupiny, karboxylové skupiny, skupiny anhydridov karboxylových kyselín alebo epoxyskupiny.

Vhodné vytvrdzovacie, resp. vulkanizačné prostriedky, urýchľovače alebo katalyzátory závisia od reaktívnych a/alebo funkčných skupín zvolených polymérov. Pre reakciu vytvrdzovania cez olefinické dvojité väzby (vulkanizáciu) tekutých a/alebo tuhých kaučukov sú vhodné radikálové vulkanizačné systémy, najmä na báze organických a anorganických peroxidov, vulkanizačné systémy na báze síry, najmä v kombinácii s organickými vulkanizačnými urýchľovačmi, a prípadne zlúčeninami zinku, vhodné sú však aj vulkanizačné systémy chinónové, dioxímové alebo dinitrozobenzolové.Suitable curing resp. the vulcanizing agents, accelerators or catalysts depend on the reactive and / or functional groups of the selected polymers. For the curing reaction via olefinic double bonds (vulcanization) of liquid and / or solid rubbers, free-radical vulcanization systems, in particular based on organic and inorganic peroxides, sulfur-based vulcanization systems, in particular in combination with organic vulcanization accelerators, and optionally zinc compounds are suitable however, vulcanization systems are also quinone, dioxime or dinitrozobenzole.
Zvlášť výhodné sú vulkanizačné systémy na báze práškovej síry, najmä v kombinácii s vulkanizačnými urýchľovačmi, ako napr. merkaptobenzotiazolom, ditiokarbamátmi, sulfénamidmi, disulfidmi, ako napr. dibenzotiazoldisulfidom a/alebo tiuramdisulfidom, aldehyd-amínovými urýchľovačmi, guanidínmi a oxidmi kovov, ako napr. oxidom zinočnatým. Naviac môžu byť vo formulácii prítomné typické kaučukové vulkanizačné prostriedky, ako napr. mastné kyseliny (napr. kyselina stearová). Obsah síry sa pritom môže meniť v širokom rozsahu, môže byť do 5 % hmotn. , s výhodou do asi 1.0 % hmotn., spodná hranica by s výhodou nemala ležať pod 3 % hmotn.. Pritom obsah síry závisí od reaktivity použitých kaučukov, najmä tekutých kaučukov. Okrem toho sa obsahom síry dá ovplyvniť maximum stratového činiteľa, ako aj využiteľný teplotný rozsah dostatočne vysokého stratového činiteľa. Obsah vulkanizačných urýchľovačov sa môže meniť medzi 0 a asi 10 % hmotn.. Aj obsah oxidov kovov je v rozsahu medzi 0 a 10 % hmotn..Particularly preferred are sulfur powder vulcanization systems, particularly in combination with vulcanization accelerators such as e.g. mercaptobenzothiazole, dithiocarbamates, sulfenamides, disulfides such as e.g. dibenzothiazole disulfide and / or thiuram disulfide, aldehyde amine accelerators, guanidines and metal oxides such as e.g. zinc oxide. In addition, typical rubber vulcanizing agents, such as e.g. fatty acids (e.g. stearic acid). The sulfur content can vary within wide limits, up to 5 wt. The lower limit should preferably not lie below 3% by weight. The sulfur content depends on the reactivity of the rubbers used, in particular the liquid rubbers. In addition, the maximum loss factor as well as the usable temperature range of a sufficiently high loss factor can be influenced by the sulfur content. The content of vulcanization accelerators may vary between 0 and about 10% by weight. Also the content of metal oxides is in the range between 0 and 10% by weight.
Ako bezsírové vulkanizačné systémy sú vhodné najmä vulkanizačné systémy na báze p-benzochinóndioxímu, pričom tieto zmesi môžu naviac obsahovať vyššie uvedené vulkanizačné urýchľovače a/alebo zlúčeniny kovov vo vyššie uvedených rozsahoch množstiev.Particularly suitable as sulfur-free vulcanization systems are vulcanization systems based on p-benzoquinone dioxime, which mixtures may additionally contain the abovementioned vulcanization accelerators and / or metal compounds in the abovementioned ranges of amounts.
Proti termickej, termooxidačnej alebo ozónovej degradácii zmesí podľa tohto vynálezu možno použiť bežné stabilizátory, ako napr. stéricky bránené fenoly alebo amínové deriváty, typické rozsahy množstiev pre tieto stabilizátory sú 0,1 až 5 % hmotn..Conventional stabilizers, such as, for example, can be used against thermal, thermo-oxidative or ozone degradation of the compositions of the present invention. sterically hindered phenols or amine derivatives, typical amount ranges for these stabilizers are 0.1 to 5% by weight.
Hoci reológiu zmesí podľa tohto vynálezu možno normálne priviesť do žiaducej oblasti voľbou plnív a pomerom množstiev nízkomolekulových tekutých kaučukov, možno použiť bež né reologické pomocné prostriedky, ako napr. pyrogénne kyseliny kremičité, bentóny alebo fibrilované alebo pulpové krátke vlákna v oblasti medzi 0,1a 7 %. Okrem toho sa v zmesiach podľa tohto vynálezu dajú použiť ďalšie bežné pomocné a prídavné prostriedky.Although the rheology of the compositions of the present invention can normally be brought to the desired area by the choice of fillers and the ratio of the amounts of low molecular weight liquid rubbers, conventional rheological auxiliaries such as e.g. pyrogenic silicas, bentones or fibrillated or pulp short fibers in the range between 0,1 and 7%. In addition, other conventional adjuvants and additives may be used in the compositions of the present invention.
Účinnosť akustického tlmenia zmesi podľa tohto vynálezu možno ovplyvniť podľa špecifických požiadaviek na použitie s ohľadom na polohu maxima stratového činiteľa, ako aj teplotného rozsahu, v ktorom bude pôsobiť extrémne vysoké akustické tlmenie. Hlavnými faktormi ovplyvnenia pri tom sú vulkanizačný systém (obsah síry, obsah vulkanizačných urýchľovačov) a obsah a reaktivita kaučukov, najmä tekutých kaučukov. Ako sme už uviedli, pridanie vhodných termoplastických polymérových práškov môže pozitívne ovplyvniť tak maximum, ako aj teplotný rozsah účinného akustického tlmenia. Do istej miery môže akustické vlastnosti ovplyvniť aj voľba druhu a množstva plnív, tu sa ukázalo, že najmä lístkovité plnivá, ako napr. sľudy, majú výhodný vplyv na stratový činiteľ. Naviac možno stratový činiteľ ovplyvniť hrúbkou nanesenej vrstvy. Ako je známe, penové materiály spôsobujú vyšší stratový činiteľ, hoci toto nebude použiteľné v takých prípadoch, v ktorých sa pre lepidlo požaduje vysoká pevnosť v strihu pri namáhaní ťahom. Vo väčšine prípadov použitia je žiaduce, aby maximum stratového činiteľa ležalo približne pri teplote miestnosti (asi 20 °C) a aby sa oblasť vysokého tlmenia (stratový činiteľ > 0,1) rozprestierala v čo najširšom teplotnom rozsahu. Podmienky vytvrdzovania sa pre lepiace/tesniace materiály, resp. zmesi na nanášanie vrstiev podľa tohto vynálezu môžu prispôsobiť špecifickej aplikácii. Ako sme uviedli na začiatku, jednou výhodnou oblasťou použitia je hrubá montáž v automobilovom priemysle, takže vytvrdzovanie zmesí sa má uskutočniť v teplotnom rozsahu medzi 80 eC a 240 °C v priebehu 10 až 35 minút, s výhodou sa pri hrubej montáži použijú teploty medzi 160 a 200 °C. Rozhodujúcou výhodou zmesí podľa tohto vynálezu voči plastisólom podľa doterajšieho stavu techniky je ich takzvaná odolnosť proti zmytiu bezprostredne po nanesení lepidiel, t.j. nevy zadujú žiadne predželatínovanie ako plastisóly, aby boli odolné v rôznych umývacích a fosfátovacích kúpeľoch pri hrubej montáži. V nasledujúcich príkladoch uskutočnenia vynález bližšie objasníme, pričom výber príkladov nemá predstavovať žiadne obmedzenie rozsahu predmetu vynálezu.The acoustic damping performance of the composition of the present invention can be influenced according to the specific requirements for use with respect to the position of the maximum loss factor as well as the temperature range over which the extremely high acoustic damping will effect. The main influencing factors are the vulcanization system (sulfur content, vulcanization accelerator content) and the content and reactivity of rubbers, in particular liquid rubbers. As already mentioned, the addition of suitable thermoplastic polymer powders can positively affect both the maximum and the temperature range of effective acoustic damping. To some extent, the choice of the type and amount of fillers may also influence the acoustic properties. mica have a beneficial effect on the loss factor. In addition, the loss factor can be influenced by the thickness of the deposited layer. As is known, foam materials cause a higher loss factor, although this will not be applicable in those cases where high shear strength is required for the adhesive under tensile stress. In most applications, it is desirable that the maximum loss factor lies at about room temperature (about 20 ° C) and that the high damping region (loss factor> 0.1) extends over the broadest possible temperature range. Curing conditions for adhesives / sealants, resp. The coating compositions of the present invention may be adapted to a specific application. As mentioned in the beginning, one preferred field of application is shell construction in the automotive industry so that the curing of the compositions to take place in a temperature range between 80 e C and 240 ° C for 10-35 minutes, preferably at shell construction is temperature between the 160 and 200 ° C. A decisive advantage of the compositions of the present invention against the plastisols of the prior art is their so-called wash resistance immediately after application of the adhesives, i.e. they do not require any pregelatinization as plastisols to be resistant in various washing and phosphating baths for rough assembly. The following examples illustrate the invention in more detail, and the choice of examples is not intended to limit the scope of the invention in any way.
Vlastnosť akustického tlmenia zmesí sa pritom v príkladoch stanovovala podľa Oberstovej metódy, ako je opísané v DIN 53440, Časť 3, pomocou oceľových pásikov s nanesenou vrstvou. Vytvrdenie nanesenej vrstvy sa pritom uskutočnilo v bežnej laboratórnej skriňovej sušičke. Pokiaľ nie je uvedené ináč, všetky diely v nasledujúcich príkladoch sú hmot nostné diely.The acoustic damping properties of the mixtures were determined in the examples according to the Oberst method, as described in DIN 53440, Part 3, by means of coated steel strips. Curing of the deposited layer was carried out in a conventional laboratory box dryer. Unless otherwise stated, all parts in the following examples are by weight.

Akustické tlmivé vlastnostiAcoustic damping properties
Na 1 mm hrubé pásiky z pružinovej ocele s rozmermi 240 mm x 10 mm sa na 200 mm dlhý úsek naniesla vrstva produktov z príkladov 1 až 3, ako aj z porovnávacieho príkladu 4, potom sa nanesené vrstvy vytvrdzovali 30 min. pri 180 °C. Stanovenie hodnoty (d-combi) akustického tlmenia sa pritom uskutočnilo podľa pokusu s kmitavým namáhaním ohybom podľa DIN 53440, Časť 3, pri 200 Hz. Pritom sa normovalo na hmotnosť nanesenej vrstvy 50 %, t.j. hmotnosť nanesenej vrstvy s akusticky tlmiacim lepiacim/tesniacim materiálom bola 50 % hmotnosti plechu.A layer of the products of Examples 1 to 3 as well as Comparative Example 4 was applied to a 200 mm long section of 1 mm thick spring steel strips of 240 mm x 10 mm, then cured for 30 minutes. at 180 ° C. The determination (d-combi) of the acoustic damping was carried out in accordance with the bending experiment according to DIN 53440, Part 3, at 200 Hz. 50% of the coating weight was standardized, i.e. the weight of the applied acoustically damping / sealing material layer was 50% by weight of the sheet.
Grafika ukazuje teplotnú závislosť akustického tlmenia d(combi) 50 % príkladov 1 až 3, ako aj porovnávacieho príkladu 4, ktorý je menej zosieťovaný.The graphic shows the temperature dependence of acoustic damping d (combi) of 50% of Examples 1 to 3, as well as Comparative Example 4, which is less crosslinked.
Porovnávací príklad 4 ukazuje najmä, že obsah síry >3 % a urýchľovačov bez dostatočného obsahu reaktívneho kaučuku nevedie k zosieťovaniu podľa tohto vynálezu a tým k dobrému akustickému tlmeniu.In particular, Comparative Example 4 shows that the sulfur content of > 3% and accelerators without sufficient reactive rubber content do not lead to crosslinking according to the invention and thus to good acoustic attenuation.
