Definitions
- the invention relates to a self-adhesive protective film for protecting glass surfaces with a porous SiO 2 antireflective layer in order to protect them from scratching after manufacture until their final use during storage, transport and assembly.
- renewable energy sources are receiving increasing attention.
- One method of sustainable energy generation is solar technology, with which electricity can be obtained from photovoltaic cells and thermal energy from solar collectors.
- Such modules are conventionally covered with window glass in order to protect the active components from environmental influences.
- Part of the energetic radiation is reflected at the glass / air interface, especially in the case of oblique radiation, which reduces the efficiency.
- a suitable method for reducing the reflection on glass surfaces is to produce a porous SiO 2 layer on glass with which a sufficiently low refractive index can be achieved in order to almost completely prevent the reflection over a broad wavelength band through destructive interference.
- a protective film for this purpose does not have to be transparent, it is even advantageously pigmented white, since it protects the absorber against overheating before starting up the solar module, in particular in the case of solar collectors.
- Protective films of this type that are to be applied temporarily are widely used for the paint protection of new motor vehicles and are described, for example, in DE 195 32 220 A1 and EP 0 827 526 A1. These can also be glued to glass surfaces and meet the criterion of weather resistance in an excellent manner. These films can be removed from window glass even after months of outdoor exposure without tearing or adhesive residues.
- EP 0 519 278 A2 discloses an adhesive applied to a film, which in turn serves to protect automobiles.
- the pressure sensitive adhesive is based on polyisobutylene rubber, which has a dynamic modulus of elasticity of 2 x 10 5 to 7 x 10 6 dynes / cm 2 , which corresponds to a value of 2 x 10 4 to 70 x 10 4 Pa in SI units at 60 ° C ,
- the adhesive can also be mixed with a silicone oil or a low molecular weight acrylic polymer.
- DE 196 35 704 A1 describes a self-adhesive surface protection film made of polyolefins with an adhesive made of polyethylene vinyl acetate (EVA) with a vinyl acetate content of 40 mol% to 80 mol%, in particular 70 mol%, and with a loss angle tan ⁇ of 0.6 to 1, 0, measured at a temperature of 60 ° C and a frequency of 10 "2 Hz, and from 0.4 to 0.7, measured at a temperature of 60 ° C and a frequency of 10 Hz.
- EVA in The claimed shape has good initial adhesion to paint and good paint compatibility. Window foils that change the properties of the glued panes are often described, for example by darkening tint, IR absorption for heat insulation or anti-reflective coatings.
- US Pat. No. 5,925,453 A describes a window film which is light-reflecting and IR-absorbent and can be glued to the inside of curved car windows.
- Possible carrier materials that can also be mixed with the IR absorbent include: Polyolefins such as polyethylene and polypropylene, polyvinyl chloride and polyesters such as polyethylene terephthalate and polybutylene terephthalate are preferred.
- Self-adhesive compositions, including synthetic rubbers such as styrene-butadiene rubber, polyisobutylene, styrene block copolymers and polyethylene vinyl acetate, and heat-moisture-activatable compositions are listed as possible adhesive compositions.
- the film described has no protective function, above all because it is applied to the concave glass surfaces from the inside.
- Such articles are usually intended for permanent bonding and must therefore meet other requirements.
- the SiO 2 anti-reflective coating After peeling off the few self-adhesive compositions that can be removed with great care without leaving any residues, or after removing adhesive residues with suitable solvents such as petrol or acetone, the SiO 2 anti-reflective coating has nevertheless undergone an irreversible change. Visually, it appears almost like untreated window glass, which means that the anti-reflective effect has decreased significantly.
- the polymers of the self-adhesive or other components of the self-adhesive such as resins, plasticizers or the like migrate deep into the micropores of the SiO 2 antireflection layer and can no longer be removed from them completely.
- the object of the invention is to provide a self-adhesive protective article for glass surfaces with a porous SiO 2 anti-reflective layer, which has the disadvantages of the prior art Technology does not show or not to the extent.
- the article should be removable from the porous SiO 2 anti-reflective layer in such a way that even after months of exposure to the outside, no irreversible changes in the anti-reflective effect occur. Any remaining changes in the antireflection effect should be completely removable with household solvents (for example methylated spirits (ethanol)) without strong mechanical action on the sensitive porous SiO 2 antireflection layer.
- the invention relates to a self-adhesive protective film for mechanical protection of glass surfaces with porous SiO 2 anti-reflective layers with a carrier made of film and a self-adhesive applied to the carrier, the self-adhesive containing at least one copolymer of ethylene and vinyl acetate, the content of vinyl acetate in the polyethylene vinyl acetate is preferably at least 40% by weight, particularly preferably 55 to 70% by weight, and polyalkylene glycols are added to the self-adhesive composition.

- Polybutylene glycol and / or polypropylene glycol are advantageously added to the self-adhesive composition, in particular 5 to 20% by weight (based on the self-adhesive composition), very particularly preferably 8 to 15% by weight (based on the self-adhesive composition).
- Polyethylene glycols (polyethylene oxides) is the name for polyalkylene glycols of the general formula belonging to the class of polyethers:
- Polyethylene glycols are produced industrially by anionic ring opening polymerization of ethylene oxide (oxirane), usually in the presence of small amounts of water.
- Liquid products with molecular weights ⁇ approx. 25,000 g / mol are referred to as the actual polyethylene glycols, abbreviation PEG, the higher molecular weight solid (melting point approx. 65 ° C.) as polyethylene oxides, abbreviation PEOX.
- High molecular weight polyethylene oxides have an extremely low concentration of reactive hydroxy end groups and therefore only show weak glycol properties.
- Branched polyadducts of ethylene glycol with polyhydric alcohols are also referred to as polyethylene glycols.
- PPG Polypropylene glycols
- the polypropylene glycols are formed by the ring opening polymerization of propylene oxide. As glycol ethers, they are considered polyethers in a broader sense. The simplest representatives of the polypropylene glycols are di-, tri- and tetrapropylene glycol.
- non-stretched foils which have sufficient flexibility to be able to be glued almost wrinkle-free even on curved surfaces.
- Polyethylene, polypropylene, propylene ethylene copolymers or mixtures thereof are particularly suitable as polymers.
- HALS food protection agents such as dimethyl succinate polymer with 4-hydroxy-2,2,6,6-tetramethyl-1-piperidine ethanol (CAS No. 65447-77-0), bis (2,2, 6,6-tetramethyl-4-piperidinyl) sebacate (CAS No.
- the amount of the light stabilizer should be at least 0.15, preferably at least 0.30% by weight, based on the carrier film.
- fillers such as titanium dioxide, which also give the film a white color, which is often desirable in opaque areas.
- the carrier is an unstretched film 30 to 120 ⁇ m thick, preferably 35 to 80 ⁇ m thick, which consists of a random propylene ethylene copolymer with 2 to 10% by weight, preferably 4 to 8% by weight. % Ethylene content and contains more than 0.3% by weight, preferably more than 0.5% by weight, of a light stabilizer.
- a suitable primer for anchoring is preferably present between the self-adhesive composition and the film, EVA types with a VA content of 20 to 50% by weight being particularly suitable, preferably 20 to 40% by weight.
- the thickness of the primer is in particular 5 to 20 ⁇ m, preferably 5 to 15 ⁇ m. Corona pretreatment is also effective in the case of coating from solution.
- the primer is advantageously coextruded with the carrier layer.
- an additional release lacquer can be advantageous for easier unrolling, especially of very wide protective films in rolled up form up to 2 m wide, the effective components of which can be, for example, silicones or waxes. Otherwise, irreversible stretching can occur when the film is deliberately stretched.
- the self-adhesive composition is preferably applied to the film in an application thickness of 8 to 50 g / m 2 , particularly preferably 10 to 30 g / m 2 . It guarantees a sufficient cushion of mass to flow flush and shows the best compatibility with sensitive surfaces without leaving any residue.
- the self-adhesive can be processed both from solution and from the melt, that is to say as a hot melt, or by coextrusion.
- the outstanding properties of the self-adhesive protective film enable it to be used on glass surfaces with a porous SiO 2 anti-reflective layer in a particularly outstanding manner.
- the concept of the invention then also includes a self-adhesive composition which contains at least one copolymer of ethylene and vinyl acetate, the content of vinyl acetate in the polyethylene vinyl acetate preferably being at least 40% by weight, particularly preferably 55 to 70% by weight, and the self-adhesive composition being Additive polyalkylene glycols are added.

- EVA polyethylene vinyl acetate
- MFI melt index
- M w 200 to 100,000 g / mol
- the adhesive composition is composed as follows:
- the EVA in the form described forms the polymer backbone of the adhesive with a moderately pronounced tack on polished or shiny metal, plastic, glass and lacquer surfaces and a rapidly increasing adhesive force on it, which assumes its final value within a few days, which accelerates when exposed to heat is achieved.
- the molecular weight which correlates directly with the MFI, plays a decisive role in relation to the cohesiveness of the adhesive.
- An MFI of 1 to 5 should be considered a favorable value.
- the addition of part of the EVA with an MFI of up to 25 can, however, contribute to improving the flow properties if the adhesive is to be applied from the melt or coextruded together with a carrier.
- polyethers reduce adhesive strength while at the same time maintaining the required tackiness, aging stability, harmlessness to health and the environment, freedom from discolouration even from white surfaces and the absence of deposits on the glued surfaces after unmasking.
- different molar masses prove to be suitable for preventing immigration and the associated swelling, particularly of plastic and paint surfaces.
- the rolling behavior of the protective films wound into rolls, which are produced with this adhesive is also significantly reduced compared to a pure EVA compound.
- the adhesive force-reducing effect can be regulated continuously.
- the adhesive tape can be easily removed from the porous SiO 2 anti-reflective layer even after several months of outdoor exposure and the remaining covering can be completely removed with simple means.
- the invention will be explained with the aid of examples, but without wishing to restrict it thereby.
- All sample films were coated by coating a 60 ⁇ m thick, corona-pretreated polyethylene carrier (composed of 90 percent by weight HDPE with a melt flow rate at 190 ° C./2.16 kg (ISO 1133) of 0.2 g / 10 min, 9.7 percent by weight titanium dioxide and 0.3 percent by weight Tinuvin 770, Ciba-Geigy) with the solutions of the individual adhesive formulations.
- a 60 ⁇ m thick, corona-pretreated polyethylene carrier composed of 90 percent by weight HDPE with a melt flow rate at 190 ° C./2.16 kg (ISO 1133) of 0.2 g / 10 min, 9.7 percent by weight titanium dioxide and 0.3 percent by weight Tinuvin 770, Ciba-Geigy
- the layer thickness of the pressure-sensitive adhesive was 20 ⁇ m after drying, so that the samples had a total thickness of 80 ⁇ m.
- compositions of the example self-adhesive compositions are listed in the table below:
- the reaction temperature was 800 ° C.
- the glass sample coated on one side for reference purposes was obtained by masking the immersed pane on one side with a protective film which, together with the adhering sol, was peeled off before the high-temperature treatment.
- the strips were peeled off at a peel angle of 180 ° and at a speed of 0.3 m / min using a tensile testing machine.
- the formerly glued area was then visually checked for residues of adhesive by breaking the cohesion within the mass or breaking the adhesive to the carrier.
- the visible tape track was wiped three times with a cloth soaked in ethanol.
- these were first removed with petrol or acetone and then wiped three times over the visible tape track with a cloth soaked in ethanol.
- a grating spectrophotometer With the help of a grating spectrophotometer, the transmission of the solar spectrum was measured at the place where it was stuck.
- the examples according to the invention have an adhesive strength which enables the protective films to be removed effortlessly. They therefore do not leave any residues of adhesive due to cohesive breakage within the adhesive or breakage of adhesion to the carrier.
- the anti-reflective effect is completely restored after treatment with ethanol.
