Oblasť technikyTechnical field
Vynález sa týka ochrannej fólie, ktorá je na ochranu povrchu nalepená na plechové pruhy alebo pásy s povrchovým povlakom vo forme lakovania alebo podobne.BACKGROUND OF THE INVENTION The present invention relates to a protective film which is adhered to surface strips or sheets with a surface coating in the form of a lacquer or the like to protect the surface.
DoteraiSí stav technikyBACKGROUND OF THE INVENTION
Také plechy, vybavené povlakovou vrstvou, sa používajú v priemysle a stavebníctve po najrôznejšom ďalšom spracovaní na najrôznejšie účely. Ochranná fólia, vyrobená spravidla z plastu, pritom slúži na to, aby povrchový povlak plechov, ktorý je väčšinou citlivý na poškodenie, bol počas transportu a ďalšieho spracovania chránený pred poškodením. To je napríklad zvlášť dôležité u plechov na obklady striech a stien, u ktorých nie je možné počas montáže zabrániť, aby na tento povrch pracovníci občas vstupovali a chodili po ňom. Po montáži plechov sa ochranná fólia spravidla stiahne a odkryje sa povrchový povlak plechov.Such coated sheets are used in industry and construction after a variety of further processing for a variety of purposes. The protective film, usually made of plastic, serves to protect the surface coating of the sheets, which is usually susceptible to damage, from damage during transport and further processing. This is particularly important, for example, for roof and wall cladding sheets, where it is not possible to prevent workers from entering and walking on this surface occasionally during assembly. After the sheets have been assembled, the protective film is generally removed and the surface coating of the sheets is exposed.
Obvykle používané ochranné fólie sú väčšinou z polyetylénovej fólie, ktorá je na jednej strane vybavená povlakom priľnavého lepidla a na druhej strane potlačená propagačnou potlačou a pokrytá tzv. uvoľňovacím lakom (napr. uretánamidovým alebo karbamidovým lakom). Priľnavé lepidlo umožňuje nalepenie ochranných fólií na povrch, určený na ochranu a popr. vybavený povlakom plechového pruhu alebo plechového pásu. Uvoľňovací lak slúži na jednej strane na zmenšenie priľnavosti medzi vrstvami fólie v rolni, a tým na zmenšenie odporu pri odvíjaní fólii, na druhej strane ako hradlová vrstva na zamedzenie difúzie farieb z potlače fólií na kontaktné plochy.Commonly used protective foils are mostly polyethylene foil, which on the one hand is coated with an adhesive adhesive and on the other hand it is printed with a promotional printing and covered with a so-called adhesive film. a release lacquer (e.g., urethane or carbamide lacquer). Adhesive adhesive allows the protective foils to be adhered to the surface to be protected and, if necessary, to be protected. coated with a sheet metal strip or sheet. The release lacquer serves, on the one hand, to reduce adhesion between the film layers in the roll and thereby to reduce the film unwinding resistance, on the other hand, as a gate layer to prevent diffusion of paint from the film imprint onto the contact surfaces.
VDE-G 90 11 117.6 sa opisuje použitie odstrániteľných ochranných fólií na ochranu povrchov predlakovaných pruhov plechu pri montáži ako strešných alebo stenových obkladov. Tieto bežne známe ochranné fólie majú tú nevýhodu, že hlavne pri vlhkosti nie sú odolné proti pošmyknutiu. Pri chôdzi po streche pokrývanej plechmi s takýmito ochrannými fóliami vzniká zvýšené nebezpečenstvo úrazu, pričom u väčších sklonov strechy toto nebezpečenstvo vzniká dokonca už pri suchom povrchu fólie. Sklon ku šmýkaniu je u bežne používanej ochrannej fólie spôsobený materiálmi používanými pri výrobe fólie. Tak napr. uvoľňovací lak, ktorý pokrýva povrch, s ktorým sa pri chôdzi prichádza do styku, má prirodzene nízky koeficient šmykového trenia μο= 0,35 až 0,38, t.j. má nežiadúci účinok šmykovej vrstvy. Koeficient šmykového trenia μο (číslo šmykového trenia) sa stanoví podľa DIN 53375 B. Tiež samotné hojne používané polyetylénové fólie majú len nízky koeficient šmykového trenia, t.j. samotná polyetylénová fólia bez pokrytia uvoľňovacím lakom je nebezpečne šmykľavá, čo je potvrdené aj tým, že polyetylénové fólie sa v literatúre označujú ako šmykové fólie.VDE-G 90 11 117.6 describes the use of removable protective films to protect the surfaces of pre-painted strips of sheet metal when installed as roof or wall cladding. These commonly known protective films have the disadvantage that they are not slip-resistant, especially when moisture is present. When walking on a roof covered with sheets with such protective foils, there is an increased risk of injury, and with larger roof pitches, this risk even arises even when the foil surface is dry. The tendency to slip in a commonly used protective film is due to the materials used in the production of the film. So eg. the release lacquer which covers the surface with which it comes into contact has a naturally low shear friction coefficient μο = 0.35 to 0.38, i. has the undesirable effect of the shear layer. The shear friction coefficient μο (shear friction number) is determined according to DIN 53375 B. Also, the widely used polyethylene films have only a low shear friction coefficient, i. the polyethylene film itself without the release lacquer coating is dangerously slippery, which is also confirmed by the fact that polyethylene films are referred to in the literature as shear films.
Technickým problémom, ktorý rieši vynález, je vytvoriť ochrannú fóliu na ochranu povrchu predlakovaných plechov pre strešné a stenové obklady, ktorá je ľahko odstrániteľná a ktorá pri manipulácii, hlavne pri chôdzi po ochrannej fólii odstraňuje nebezpečenstvo pošmyknutia. Podstata vynálezuThe technical problem solved by the invention is to provide a protective film for protecting the surface of pre-painted sheets for roofing and wall cladding that is easily removable and which removes the risk of slipping when handling, especially when walking on the protective film. SUMMARY OF THE INVENTION
Tento problém sa podľa vynálezu rieši tým, že povrch ochrannej fólie, určený na manipuláciu má koeficient šmykového trenia najmenej μο = 0,6 a výhodne najmenej μο= 0,8. Ochranná fólia je výhodne samolepiaca a/alebo odstrániteľná.This problem is solved according to the invention in that the surface of the protective film to be handled has a shear coefficient of at least μο = 0.6 and preferably at least μο = 0.8. The protective film is preferably self-adhesive and / or removable.
Vo výhodnom uskutočnení je ochranná fólia namiesto bežne používaného uvoľňovacieho laku vybavená krycím lakom. Pomocou krycieho laku môžu byť súčasne zachované známe vlastnosti nízkeho odporu pri odvinovaní z rolne aj účinok ochrany povrchu proti difúzii farby. Krycí lak je integrálnou súčasťou ochrannej fólie a slúži na to, aby prepožičal povrchu fólie žiadané vlastnosti, keď základný materiál fólie už tieto vlastnosti sám nemá.In a preferred embodiment, the protective film is provided with a topcoat instead of a conventional release lacquer. By means of the topcoat, the known properties of the low roll-off resistance and the effect of protecting the surface against diffusion of the paint can be maintained at the same time. The topcoat is an integral part of the protective film and serves to impart desirable properties to the film surface when the base material of the film no longer possesses these properties.
Je tiež možné, že krycí lak je nanesený na vhodnú medzivrstvu alebo priehradnú vrstvu, aby napr. zabránil difúzii farby z potlače fólie na kontaktné plochy.It is also possible that the topcoat is applied to a suitable intermediate layer or barrier layer, e.g. prevent diffusion of ink from the film imprint onto the contact surfaces.
Ako krycí lak je výhodne používaný lak z alifatických polyamidov na báze nenasýtených mastných kyselín. Ako krycí lak môže byť tiež výhodne použitý lak na báze polyuretánu s PVCprotišmykovými olejmi. V týchto prípadoch môže byť výhodné použiť v krycom oleji prídavok polyamidu vo forme prášku, pričom podiel polyamidu sa nerozpúšťa v oleji buď vôbec, alebo sa rozpúšťa len neúplne, takže nerozpustené polyamidové častice spôsobia po zaschnutí krycieho laku zvýšenie drsnosti povrchu krycieho laku.As the topcoat, an aliphatic polyamide lacquer based on unsaturated fatty acids is preferably used. A polyurethane-based lacquer with PVC antiskid oils can also be advantageously used as a topcoat. In these cases, it may be advantageous to use a polyamide powder addition in the coating oil, wherein the polyamide fraction either does not dissolve in the oil at all or only dissolves incompletely so that the undissolved polyamide particles cause an increase in surface roughness of the coating after drying.
Krycí lak sa môže nanášať nielen celoplošne, ale tiež ako bodový alebo líniový raster priamo na povrch ochrannej fólie.The topcoat can be applied not only over the entire surface, but also as a spot or line grid directly on the surface of the protective film.
V ďalšom uskutočnení má ochranná fólia zvlášť vyrobené povrchové štruktúrovanie, ktoré sa výhodne vyrába raziacimi valcami alebo nanášaním zrnitých substancií do základnej hmoty ochrannej fólie. Aby sa nezvyšoval odvíjací odpor z rolne fólie nežiadúcou mierou, môže aj tu byť výhodné, aby povrchové štruktúrovanie ochrannej fólie bolo uskutočnené len rastrovo alebo miestne obmedzené.In another embodiment, the protective film has a specially fabricated surface structuring which is preferably produced by embossing rollers or by applying granular substances to the protective film matrix. In order not to increase the unwinding resistance of the film roll in an undesirable manner, it may also be advantageous here that the surface structuring of the protective film is performed only in a raster or locally limited manner.
V ďalšom výhodnom uskutočnení obsahuje spravidla z polyetylénu zhotovená ochranná fólia prídavky polyamidov, pričom ich obsah je prispôsobený tak, aby sa dosiahol vysoký koeficient šmykového trenia. Tieto prídavky polyamidov je možné realizovať v práškovej forme. Alternatívne je ochranná fólia zhotovená úplne z polyamidu. Toto uskutočnenie prichádza do úvahy hlavne vtedy, keď sa upustí od povrchového potlačenia ochrannej fólie a nie je teda potrebná zábrana proti difúznemu prenosu farby.In a further preferred embodiment, the protective film generally made of polyethylene comprises additions of polyamides, the content of which is adapted to achieve a high coefficient of shear friction. These polyamide additions may be in powder form. Alternatively, the protective film is made entirely of polyamide. This embodiment is particularly suitable when surface suppression of the protective film is dispensed with and hence no diffusion barrier is required.
Naviac je možné vybaviť ochrannú fóliu podľa vynálezu líniovo usporiadanými perforáciami alebo podobnými zoslabeniami materiálu, ktoré sú určené na oddelenie oblasti fólie, ohraničenej perforáciou, od ostatných oblastí ochrannej fólie. Toto uskutočnenie umožňuje jednoduchým spôsobom odstrániť pásy ochrannej fólie v presne potrebnom rozsahu z chráneného, povlakom vybaveného povrchu plechu, a to nielen iba odhrnúť lepivú stranu nahor, ale úplne odstrániť. Tým je umožnené vykonávať drážkové spoje medzi plechmi s povrchovým povlakom a s ochrannou fóliou bez toho, aby sa fólia zovrela v drážkovom šve a zostala tam priškripnutá, alebo bez toho, aby preložená ochranná fólia prekážala pri ďalších prácach a pôsobila ako zachytávač špiny a musela byť potom z nutnosti odstránená.In addition, it is possible to provide the protective film according to the invention with linear perforations or similar weaknesses of the material, which are intended to separate the region of the film bounded by the perforation from the other areas of the protective film. This embodiment makes it possible in a simple manner to remove the protective film strips to the exact extent necessary from the protected, coated surface of the sheet, not only to remove the adhesive side up, but to remove them completely. This makes it possible to make groove joints between the coated sheets and the protective film without the film clamping in the seam and being pinched there, or without the folded protective film interfering with further work and acting as a dirt trap and then has to be removed from necessity.
