Abstract
Uppfinningen avser ett material för transportskydd av fordon och metod för framställning avett sådant material. Materialet utgörs av ett laminat som består av ett första skikt i form av enplastfilm (1) och ett andra skikt i form av ett non-woven fibertyg (2) och varvid de bådaskikten är sarmnanfogade med ett bindemedel (3). Fibertyget (2) har en kontrolleradñberstruktur med fibrema orienterade i två olika riktningar som bildar i huvudsak en vinkelpå 45° i förhållande till sammanfogningsriktningen vid lamineringsprocessen. De båda skikten(1, 2) är anordnade att pressas samman under reglerat tryck vid sammanfogningen.Sammanpressningen utförs med hjälp av sammanfogningsvalsar (10) med ett íörutbestämtavstånd mellan valsarna som är mindre än skiktens sammanlagda tjocklek och med ettreglerat tryck på 4 - 6 bar. Bindemedlet (3) utgörs av ett varmsmältlim som distribueras frånett limhuvud (7) i form av en s.k. slot die applicator och appliceras direkt på non-woven sidanhelt utan kontakt mellan material och limhuvud så att det fördelas över non-woven ytan i limsträngar (4) som löper kontinuerligt längs med materialet i maskinriktningen. The invention relates to a material for transport protection of vehicles and a method for producing such a material. The material consists of a laminate consisting of a first layer in the form of a single plastic film (1) and a second layer in the form of a non-woven fabric (2) and the two layers being joined together with a binder (3). The nonwoven fabric (2) has a controlled rubber structure with fi brims oriented in two different directions which form essentially an angle of 45 ° in relation to the joining direction in the lamination process. The two layers (1, 2) are arranged to be compressed under controlled pressure at the joining. The compression is carried out by means of joining rollers (10) with a predetermined distance between the rollers which is less than the total thickness of the layers and with a regulated pressure of 4-6 bar. The adhesive (3) consists of a hot melt adhesive which is distributed from an adhesive head (7) in the form of a so-called slot die applicator and is applied directly to the non-woven side completely without contact between the material and the glue head so that it is distributed over the non-woven surface in glue strands (4) which run continuously along the material in the machine direction.
Description
(J: lO 15 20 30 535 403 till kryntpliltttctt. ltirdelett med detta skulle da tara att tillåta libertyget att fungera som en dyna mellan krymplilttteit och den artikel som skall skyddas. (J: 10 15 20 30 535 403 to kryptpliltttctt. Ltirdelett with this would then tara to allow the liberty fabric to act as a cushion between krymplilttteit and the article to be protected.
För att bibehålla ”kuddeffekten” hos ñbertyget är bindningsstationen justerad på ett sådant sätt att lilmctt vid lamttteritigsprocesseit brittgas i beröringsitigrepp tned tyget titan att väsentligt tryck appliceras. En beröring av tilmen mot fibertyget är det enda som eftersträvas För att binda tilmen till tyget så att bindningen endast sker över en relativt liten procent-andel av tyget och lilntett genom att bindemedlet appliceras endast pa de ttppståettde dclarnat at tyget.In order to maintain the "cushioning effect" of the fabric, the bonding station is adjusted in such a way that during the lamination process the brit gas is in contact with the titanium fabric that substantial pressure is applied. A touch of the yarn against the fabric is the only thing that is sought. To bind the yarn to the fabric so that the bonding takes place only over a relatively small percentage of the fabric and tightly by applying the adhesive only to the ttppståttde dclarnat at the fabric.
Att liberty get är uppbyggt av slumpmässigt arrangerade non-woven librer medför dock att de inekaniska egenskaperna hos tyget är begränsade. För* att uppnå tillräckligt bra rnekaniska egenskaper hos törpackningsniaterialet innebär detta att det andra skiktet, filmen, blir styrande kör att uppnå totalt sett tillräckligt bra mekaniska egenskaper hos laminatet. l praktiken rnaste tilmetis tjocklek ökas eller också måste ytterligare lilmskikt appliceras. se WO 2010/022066. vilket lörsvárar och fördyrar lantineringsprocessen.However, the fact that the liberty goat is made up of randomly arranged non-woven libraries means that the non-mechanical properties of the fabric are limited. In order to achieve sufficiently good mechanical properties of the dry packing material, this means that the second layer, the film, becomes a driving force to achieve overall good enough mechanical properties of the laminate. In practice, the thickness of the tilmetis is increased or additional adhesive layers must be applied. see WO 2010/022066. which complicates and increases the cost of the lantinating process.
Att sammanfoga de två skikten utan att väsenligt tryck appliceras ökar också risken att de två skikten efter hand oavsiktligt separeras ifran varandra. Det kan tinnas risk för delamittcring vid applicerittg av törpackniitgstnaterialet över det fordon som skall skyddas eller under den vidare transporten av fordonet.Joining the two layers without applying significant pressure also increases the risk that the two layers will be inadvertently separated from each other. There may be a risk of delamitation when applying the dry packing material over the vehicle to be protected or during the further transport of the vehicle.
Ett ändantál med föreliggande upptintiiitg är därför att åstadkomma ett törpackningsmaterial av det inledningsvis angivna slaget där tilmen kan minskas radikalt i tjocklek med bibehållna mekaniska egenskaper hos lörpacknittgsmatcrialet.An end result of the present invention is therefore to provide a dry packing material of the type indicated in the introduction where the mold can be radically reduced in thickness while maintaining the mechanical properties of the loose packing material.
Ett ytterligare ändamål med uppfinningen är att anordna sammanfogningen av de båda skikten på ett sådant sätt att risken För delaminering hos törpackningsmaterialet minskar.A further object of the invention is to arrange the joining of the two layers in such a way that the risk of delamination of the dry packing material is reduced.
Enligt ttpplitittittgett tttgörs det andra skiktet av ett non-woven libertyg med kotttrollerad tiberstruktur med fibrerna orienterade i två olika riktningar och varvid de båda skikten är anordnade att pressas samman Linder reglerat tryck vid sammanfogningen. 15 20 25 30 535 403 2.1 Enligt en fördelaktig utlöriitgslortn är fibrerna orienterade i två olika riktningar som bildar i huvudsak en vinkel pä 45° i lörhállttiide till sammanfogningsriktningen lmaskinriktttiitgen). línligt en ytterligare lördelaktig utlöringslorm arrangeras sammanfogningen under värme i avsikt att öka vidhäftiiiitgsstyrkan mellan de båda skikten. l det löliattde skall ttppliitniiigett närmare beskrivas under hänvisning till bifogade figurer, varvid l-"ig l iir ett prineipskiss över ett lärdigt laminat. och Fig 2 är en schematisk illustration av lamineringsprocessen enligt uppfinningen.According to the tplittittittgett, the second layer is made of a non-woven libert fabric with cone-trolled tiber structure with the fibers oriented in two different directions and the two layers being arranged to be compressed Linder regulated pressure at the joining. 15 20 25 30 535 403 2.1. According to an advantageous discharge direction, the fibers are oriented in two different directions which form a substantially angle of 45 ° in the direction of attachment to the joining direction (machine direction). In addition to a further ludicrous release lumen, the joint is arranged under heat in order to increase the adhesion strength between the two layers. In the present, the invention will be described in more detail with reference to the accompanying figures, in which Fig. 1 is a principle sketch of a learned laminate, and Fig. 2 is a schematic illustration of the lamination process according to the invention.
Förpackningstnaterialet enligt figur l tttgörs av ett laminat som generellt består av ett första skikt i form av en plastfilin 1 och ett andra skikt i form av ett non-woven fibertyg 2. De båda skikten är santmaiifogade med ett bindemedel 3 i en lamineringsprocess som beskrivs iiärniare i ligur 2. Plastfiliiieii kan utgöras av en krymplilm eller ”stum” film av typen polyolelin. Plasttilnier av det här slaget är väl kända lör lackmannen och beskrivs därför ej närmare här. Det skall dock nämnas att till skillnad från de inledningsvis Omnämnda, kända lörpackningsniaterialen används i detta fall företrädesvis en ”stum” plastfilm med en _iäinlörelsevis tunn tilmtjoeklek pà SU ~ ot) um.The packaging material according to Figure 1 is made of a laminate which generally consists of a first layer in the form of a plastic filin 1 and a second layer in the form of a non-woven nonwoven fabric 2. in ligur 2. Plastic filiiiii may be a shrink film or "mute" film of the polyolelin type. Plastic tiles of this kind are well known to the painter and are therefore not described in more detail here. It should be mentioned, however, that in contrast to the initially mentioned known packing materials, a "dumb" plastic film with a relatively thin thickness of SU ~ ot) um is preferably used in this case.
Företrädesvis är filmen av en kvalitet som är UV blockerad så att den stoppar UV strålar att gä igenom inateri-alet. Detta innebär att laminatet skyddar ytskiktet pá de lörentäl som skall skyddas på ett bättre sätt än tidigare, exempelvis vid långtidsuppställttitig av fordon i varmare kliniat. UV blockering av material är i och för sig känd och kan göras effektiv så att i princip 99 % och iner av UV strålningen förhindras.Preferably, the film is of a quality that is UV blocked so that it stops UV rays from passing through the inertial material. This means that the laminate protects the surface layer of the lumber to be protected in a better way than before, for example in the case of long-term storage of vehicles in warmer clinics. UV blocking of materials is known per se and can be made effective so that in principle 99% and iners of UV radiation are prevented.
Fibertyget 2 kan också vara av ett i och för sig känt slag av typen non-woven (icke-vävd) fberduk. Till skillnad från de liberdukar med slumpmässigt orienterade fibrer som beskrivits i de ovan iiåitniidtt patenten används i detta fall en liberdttk med kontrollerad liberstruktur där fibrerna är orienterade i tva olika riktningar. löreträdesvis där de båda orienteringarna bildar i huvudsak 45° vinkel i förhållande till maskinriktningen i lamineringsprocessen. Härigenom lår liberduken i liuvtidsak samma egenskaper i alla orienteringar, vilket innebär att de 20 25 30 535 403 inekttitiskzt egenskaperna texentpelxis dragltítllltistltct) i det líirdigtt laminaitet blir itiistuii identiska i alla orientcringar. Det mesta av de mekaniska egenskaperna hos laminatet kan därmed läggas på ftberdtiken. Plastfilmens mekaniska egenskaper blir inte styrande, vilket är en väsentlig orsak till att en tunnare plasttilntskvalitet kan användas i laminatet.The nonwoven fabric 2 can also be of a per se known type of non-woven (non-woven) nonwoven type. Unlike the randomly oriented fiber cloths described in the above patents, in this case a liberdttk with controlled fiber structure is used where the fibers are oriented in two different directions. preferably where the two orientations form a substantially 45 ° angle in relation to the machine direction in the lamination process. As a result, the liberduken has essentially the same properties in all orientations, which means that the inekttitiskzt properties texentpelxis dragltítllltistltct) in the lyrical laminate become itiistuii identical in all orientations. Most of the mechanical properties of the laminate can thus be applied to the fabric. The mechanical properties of the plastic film do not become controlling, which is a significant reason why a thinner plastic grade can be used in the laminate.
Genom en sådan kross lagd non woven där fibrerna ligger i bestämda orienteringar och där det applicerade bindemedlet 3 bildar en mer kontinuerlig limbana i form av limsträitgar 4 som löper lüitgs med inaterialet i inaskinriktitiitgeit kan vidhäftitingeit mellan de båda skikten. l och 2 ökas.By means of such a crusher laid non-woven where the fibers lie in certain orientations and where the applied binder 3 forms a more continuous adhesive web in the form of adhesive strands 4 which run flush with the material in the in-direction direction, adhesion between the two layers can be. 1 and 2 are increased.
Bindetnedlet 3 utgörs av ett varmsmältlint av känt slag med en sådan konsistens att det kan appliceras direkt pä den slíitzi non-woven sidan helt utan kontakt mellan material och limhuvud, se vidare figur 2.The binder 3 consists of a hot melt ribbon of known type with such a consistency that it can be applied directly to the non-woven side completely without contact between material and glue head, see also figure 2.
Figur 2 visar schentatiskt en lamineringsprocess enligt tippftnnittgett. Fibertyg 2 och plasttilitt l levereras i rullar. 5 respektive 9. till laininerittgsattläggttingen Fibertygct 2 rullas fràn rullen 5 med ltjälp av en matar-rulle 6 till ett limhuvud 7 i form av en s.k. slot die applicator där ett varmsittâiltlint 3 appliceras direkt på itoit-woven sidan helt utan kontakt mellan ntaterial och limhuvud. limllödet styrs så att genomblödtting av limmet förhindras och så att det fördelas över itott-woven ytan i limsträngar som löper kontinuerligt längs med materialet i maskinriktitittgcn. l-'ör att bibehålla limmets temperatur är en värmekiilla i form av ett lR element 8 anordnat direkt efter limhuvudet 7 i anslutning till materialbanan. Skulle limmet kylas ner för mycket ntinskar ttämligert dess vidhäftningstörmåga och en större mängd lim skulle behöva påfóras för att uppnít tillräcklig vidhäftitittgsstyrkti.Figure 2 schematically shows a lamination process according to tippftnnittgett. Fiber fabric 2 and plastic trust l are delivered in rolls. 5 and 9, respectively. To the liner liner installation Fiber fabric 2 is rolled from the roller 5 with the aid of a feed roller 6 to a glue head 7 in the form of a so-called slot die applicator where a hot seat tape 3 is applied directly to the itoit-woven side completely without contact between the material and the glue head. the glue solder is controlled so that soaking of the glue is prevented and so that it is distributed over the woven surface in glue strands which run continuously along the material in the machine direction. In order to maintain the temperature of the adhesive, a heating wedge in the form of an IR element 8 is arranged directly after the adhesive head 7 in connection with the web of material. Should the adhesive cool down too much, its adhesion dryness decreases considerably and a larger amount of adhesive would need to be applied to achieve sufficient adhesion strength.
Plastftlinen l rullas av rullen 9 och sammanfogas med ftbertyget 2 genom två sammanfogningsvalsar lt). Alldeles innan de tvâ materialen möts i sammanfogningsvalsarna lt) törvürttts plastfilitteii l med ltiülp av en víirntekâilla i form av ett lR-element l l i anslutning till ftlmbaitatt till en temperatur på SU -9U°C. En sådan förvärmning av plastfilmen bidrar till en ökad vidhäftiting och möjliggör en minimering av limmängd. lU 20 25 30 535 403 Vid santmanfogningeit av de båda materialen pressas materialen samman mellan valsarna lU med ett förutbestämt avstànd som är mindre än materialens sammanlagda tjocklek och med ell reglerat tryck pa 4-0 bar. lför att lamineringeit skall bli bra är det viktigt att materialen verkligen pressas samman i saminanlbgiiingsinomentet, lör att Försäkra sig om att delaminering inte sker när laminatel appliceras på ett fordon eller under transport av det fordon som skall skyddas.The plastic liner 1 is rolled by the roller 9 and joined to the liner fabric 2 by two joining rollers lt). Just before the two materials meet in the joining rollers lt) törvürttts plastfilitteii l with ltiülp of a vírntekâilla in the form of a lR element l l in connection with ftlmbaitatt to a temperature of SU -9U ° C. Such preheating of the plastic film contributes to an increased adhesion and enables a minimization of the amount of glue. At the true joining of the two materials, the materials are compressed between the rollers 11U with a predetermined distance which is less than the total thickness of the materials and with a regulated pressure of 4-0 bar. In order for the lamination to be good, it is important that the materials are really compressed in the assembly laminator, but to ensure that delamination does not occur when laminate is applied to a vehicle or during transport of the vehicle to be protected.
För att uppnå en optimal limskarv mellan de två olika materialen är även samntantogitiitgsvalsarna lU ttppvärrnda till en temperatur pà S0-70°C vilket gör att limmet inte kallnar så fort i sammantogitiitgeii. Kallitar liminet alltför fort kan limmet bli ”chockat” och ger dä en svagare och sprödare limskarv. 'fillsaittinatts med itíimitda förvärnntittg av plasttilineit ger en sådan uppvärmning av sammanfogningsvalsarna processvänliga förutsättningar för ntinittteriitg av lim saint optimering av vidhäftning.In order to achieve an optimal adhesive joint between the two different materials, the joint anti-roll bars are also heated to a temperature of S0-70 ° C, which means that the adhesive does not cool down so quickly in the joint bond. If you glue the glue too fast, the glue can be "shocked" and then give a weaker and more brittle glue joint. 'fillsaittinatts with itíimitda förvärnntittg of plasttilineit provides such heating of the joining rollers process-friendly conditions for ntinittteriitg of glue saint optimization of adhesion.
