Definitions

  • the invention relates to a method for adjusting convolution amplitudes and frequencies in the photochemical matting of radiation-curable surfaces.
  • microstructure itself is topographically characterized by measures such as convolution amplitudes and folding frequencies. Both sizes determine the degree of gloss and the haptic appearance of the microstructured surface.
  • the topographical structure of the microplating is determined by the type of excimer radiator used, the dose of radiation, the formulation of the coating, the time elapsed between preparation of the microplate and final cure, and coating properties such as viscosity and temperature.
  • the viscosity of the coating is determined by the formulation and is generally matched to the coating process used. Therefore, it can not or only to a limited extent be adapted to the requirements of photochemical microfolding.
  • EP 2 794 126 A1 describes that homogeneous matte coatings can be produced if the radiation-curable coating is irradiated in a step upstream of the microfilling with long-wave, polychromatic UV radiation from, for example, gas-doped Hg medium-pressure lamps. This process step is also referred to as "Vorglellmaschine".
  • this pre-gelation is an incomplete UV cure of the coating.
  • a part, typically less than 50%, of the originally existing acrylate double bonds is implemented.
  • the long-wave, polychromatic UV radiation penetrates the entire layer and generates incomplete polymerization and crosslinking over the entire layer thickness even at radiation doses of 20-100 mJ / cm 2 .
  • the coating remains liquid, but has a higher viscosity than the unirradiated coating.
  • the frosted surface appears partly shiny and blotchy.
  • a predetermined and targeted adjustment of the amplitude and frequency of the micro-folding and thus the feel of the surface is not possible in this way.
  • the object of the present invention is to provide a method which overcomes this disadvantage.
  • monochromatic UV emitters e.g. are available as Hg low-pressure lamps.
  • a mercury discharge emits mainly Hg resonance lines at 185 and 254 nm.
  • photons having a wavelength of 185 nm are absorbed by both acrylate / methacrylate molecules and the photoinitiator.
  • the wavelength of 254 nm is in most cases above the absorption range of acrylates / methacrylates and is absorbed solely by the photoinitiator.
  • the penetration depth of 185 nm photons in acrylates / methacrylates is even lower and is between 0.5 and 1.5 ⁇ m.
  • the penetration depth of the 185 and 254 nm photons is adjusted and thus the resulting increase in the viscosity of the coating on the surface by the choice of the appropriate photoinitiator concentration.
  • the viscosity is increased in a surface layer up to a depth of 1.5 ⁇ m by absorption of the 185 nm photons.
  • a first step according to the inventive method the irradiation of the coating with short-wave monochromatic radiation of Hg resonance lines at 185 and 254 nm with doses of 60 to 1000 mJ / cm 2 , preferably from 100 to 600 mJ / cm 2 to increase Viscosity in the surface area up to depths of 10 microns, preferably realized up to 5 microns, before in a second step the irradiation of the thus provided coating with inhomogeneous depth profile of the viscosity is effected by photons of a xenon or KrCl excimer radiator for triggering the photochemical microstructuring.
  • the adjustment of convolution amplitude and frequency by irradiation of a photoinitiator-free coating with short-wavelength monochromatic radiation at 185 nm can be done with doses of 100 to 1500 mJ / cm 2 .
  • Acrylate / methacrylate formulations generally consist of higher-viscosity, oligomeric binders such as urethane, epoxy and polyester acrylates and reactive diluents such as acrylate monomers having one to four acrylate double bonds per molecule.
  • UV radiation photoinitiators are added. If electrons are used to cure the coatings, photoinitiators can be dispensed with.
  • a special type of radiation-curable formulations are nanocomposites. Here, nanoscale silica particles are incorporated into the acrylate / methacrylate matrix ( R: MEHNERT, F.BAUER, UV-CURABLE ACRYLATE NANOCOMPOSITES, J.POLYM.RES. vol.12 (2005), pages 483-491 ).
  • Low pressure mercury vapor lamps are synthetic or natural quartz gas discharge lamps that emit at wavelengths of 254 and 185 nm and have an optical efficiency of approximately 40%.
  • the spectral irradiance achievable with 185 nm photons is about 20% of that at 254 nm.
  • Hg low-pressure lamps which is more powerful by up to one order of magnitude is amalgam lamps. Because of their low power compared to Hg medium-pressure lamps, Hg low-pressure lamps are generally not used for UV curing. However, this property is an advantage if you want to achieve an incomplete surface hardening, as used in the process according to the invention.
  • Excimer lamps are gas discharge lamps with a lamp body made of synthetic quartz and a filling of xenon (xenon excimer radiator with an emission at 172 nm) or krypton with a chlorine donor (KrCl excimer radiator with an emission at 222 nm). They emit quasi-monochromatic VUV / UV radiation, which results from the decomposition of excited dimer molecules such as Ar 2 *, Xe 2 * and KrCl * ( B. ELIASON, U. KOGELSCHATZ, APPL.PHYS.B, vol. 46 (1988), pages 299-303 ).
  • the penetration depth of 126 nm photons in acrylate / methacrylate coatings is a few 10 nm, for 172 nm less than 500 nm and for 222 nm 2 ⁇ m.
  • start-up radicals are formed in the coating, which lead to polymerization and crosslinking in the surface region.
  • the surface increases by up to 20% and forms wrinkle structures. This process is called photochemical microfolding.
  • the coating remains uncrosslinked at depth. Therefore, in a subsequent step, the coating is completely cured by UV or electron beam curing.
  • WLI white light interferometry
  • This method uses the interference of broadband light.
  • the beam of a light source is split by a beam splitter.
  • One part is guided to a reference mirror, the other perpendicular to the object to be measured.
  • One beam is reflected at the reference mirror and the other at the sample to be measured. Both reflected beams are superimposed on the return path and are recorded by a camera. Interference occurs when the difference in length between Reference mirror and sample is smaller than the coherence length of the light.
  • the sample is moved vertically through the interfering region.
  • interference images are created which reflect the topography of the surface in the scan area.
  • a radiation-curable acrylate nanocomposite coating from Cetelon Nanotechnik Eilenburg (G) with the type designation 830/800 103 is applied to a melamine substrate using a laboratory curtain coater from Barberan Castelldefels (SP). The layer thickness is 90 ⁇ m. After waiting for a few seconds to set a smooth surface, the coating is irradiated with Hg low pressure lamps.
  • Ten Hg low-pressure lamps of the UVN 80 4C 15/1000 type from UV Meyer Ilmenau (G) are arranged in a geometrically parallel arrangement and are located in an irradiation chamber which, among other things, also serves to visually shield the radiation.
  • the coated samples are moved on a conveyor belt through the irradiation chamber.
  • the radiation dose is adjusted by the speed and the number of passes.
  • the dose is measured using a Dosimeter from Epigap Berlin (G). In a run with 10m / min speed, a dose of 85 mJ / cm 2 is achieved. The irradiation always takes place in air.
  • the sample is driven at a speed of 20 m / min through the beam area of a 172 nm excimer radiator.
  • the irradiation dose is set to 2mJ / cm 2 and maintained in all experiments.
  • the UV final curing is carried out by a Hg medium-pressure lamp of a specific electrical power of 150W / cm. Both excimer irradiation and UV final curing are carried out under nitrogen at oxygen contents ⁇ 50 ppm.
  • portions of the substrate can be peeled off and analyzed.
  • the surface topography of the samples is determined in this way with white light interferometry.
  • the analysis area is approximately 600 ⁇ 600 ⁇ m. As at Each position of the surface can be derived from a profile, the measurement of convolution amplitude and frequency is possible.
  • illustration 1 is a series of folding structures that were recorded in the dose range of 0 to 510 mJ / cm 2 .
  • the very coarse folding can be seen without pre-irradiation with Hg low-pressure lamps.
  • the folding is fine.
  • illustration 1 shows this connection.
  • the convolution amplitude decreases and the convolution frequency increases.
  • the surface touches the surface by hand it is found that the surface becomes smoother as the dose of pre-irradiation increases.
  • the feel of the surface is also adjustable.
  • Table 1 gives gloss values for the different samples. Without pre-irradiation a uniform matting is not possible. The feel is insufficient. However, the sample already has a deep matt, haptically appealing surface from a pre-irradiation dose of 85 mJ / cm 2 . At higher doses this tendency increases. The gloss measured at 60 ° decreases slightly with increasing dose, while the gloss value determined at 85 ° increases. However, the tested in grazing light incidence coating has a uniform matting. This evaluation is supported by the haptic test. The gloss values of the matted coatings produced by the process according to the invention can be adjusted within certain limits by the choice of the dose of irradiation with Hg low-pressure lamps.

  • Table 2 gives the gloss values of the samples. For doses between 23 and 43 mJ / cm 2 the gloss values are comparable. The gloss value at 60 ° is slightly higher than in Example 1.
