Definitions
- the invention relates to a photoluminescent granules of a cured mixture comprising a transparent light-fast matrix, in which at least one photoluminescent luminescent pigment and a transparent filler are contained.
- Effect pigments from the field of photoluminescence are used in various fields of application, eg. B. in the functional, decorative or security area. Due to the high intrinsic functionality of these pigments and the resulting changed requirements in the processing and application of these pigments, the most diverse technical challenges arise. In principle, these pigments must be metered higher in comparison with standard color pigments and are likewise miscible with standard color pigments and / or solids only with high losses in the resulting luminosity. A use in transparent, filler-less systems such. Clear lacquer, pure fluorescent colors, transparent resin systems is relatively easy to implement. In systems with fillers, however, this is not readily possible.
- the mentioned systems which include filler are e.g. Solid Surface mineral plates, e.g. known by the brand “Corian®”, or so-called
- Solid surface materials are usually a cast mixture of acrylic resins or polyester resins and a high proportion, usually greater than 50%, of eg aluminum trihydrate (ATH or Al (OH) 3 ).
- the engineered stone plates are terazzo or
- Polymer concrete-like resin-bonded systems with mineral fillers which are also common in standard concrete products, such as quartz, marble, SpNt, etc.
- the wall thicknesses of these materials are usually around 8 mm. In the area of solid surface panels, a standard thickness of approx. 12.5 mm has been established.
- the properties of these materials are determined by the ratios of resin binders (matrix) to filler, ie the filler is a core component of the definition of these products or the properties of these products, such as the B1 fire class classification of solid surface plates.
- photoluminescent variants of these materials must also contain a high proportion of corresponding fillers.
- Photoluminescent pigments very high material costs arise.
- the pigments from deeper layers can no longer contribute to the desired luminous effect due to the lack of or too little excitation.
- the pigment content can not be arbitrarily increased without affecting the material properties from a certain point strongly negative.
- photoluminescent pigments are also very difficult to use with darker materials, since the darker the environment of the pigments, the more the luminous effect is absorbed. This results in a strong decrease of the lighting effect.
- a solution could provide granules, which could then be introduced in the form of fragments of various sizes, in the plate material. These debris should be adjusted in density to either fall or rise during production, respectively in the direction of the later (visible) surface of the panel produced. This would mean that these materials would only have a very small proportion of the resulting plate material and consequently would have to be used only in very small quantities compared to the previous procedure.
- Plates and moldings containing aluminum hydroxide as a filler are becoming increasingly popular.
- the casting compounds used for the preparation are mixed with colored particles of 0.1 mm to several mm in size. In order to make these particles visible and to increase the attractiveness of the plates are ground after the preparation (curing) on the surface to expose the particles (stronger).
- the added color particles require a density at least equal to the density of the polymerizable binder / aluminum hydroxide dispersion used.
- a density of 1, 6 to 1, 8 g / cm 3 is therefore desirable.
- this density would have to be achieved without a reduction in photoluminescence
- Pigments can be achieved if photoluminescent pigments are to be used in these products.
- the density of the binder is only about 1.2 g / cm 3 . As is known, additional fillers are needed to achieve the desired density.
- these fillers should have the highest possible density and a large particle size, so that the highest possible transparency is achieved. Thus, maximum luminosity of the photoluminescent pigments on the surface after grinding should be obtained. As fillers come in the
- fillers with a low Mosh hardness are suitable for use in the present exemplary application of Corian®.
- the fillers to be used in this way additionally have to form a good bond with the binder used, but do not dissolve during processing.
- polyester or thermosetting modified acrylates are used.
- a major part of the color particles used will be out Polyester produced.
- colored plates are produced using the pigments and fillers and separated in a subsequent comminution process and screening process. The granules thus obtained are in turn used in the production of the Corian® parts.
- the object of the present invention is therefore to provide a granulate which is suitable as an additive for the abovementioned applications and to which optionally different formulations and requirements can be adapted, and has a photoluminescent effect.
- photoluminescent aggregates as granules comprising a transparent lightfast matrix the at least one photoluminescent luminescent pigment and a transparent filler are contained, wherein the filler has an average particle size of less than 30 ⁇ and / or an average particle size between 70 ⁇ and 1, 2 mm.
- a curable mixture can be obtained which, depending on the choice of fillers, is suitable as a granulate for a very wide variety of applications.
- the mean particle size of the filler is less than 30 ⁇ , in particular greater than 50 nm, more preferably greater than 100 nm, more preferably greater than 150 nm and most preferably greater than 200 nm.
- the average particle size (d 5 o) is measured under average grain size with a laser diffractometer from Malvern Mastersizer 2000 based on a volume distribution.
- transparent is understood to mean not only complete transparency or complete transparency, but also translucency, ie a high level of transparency not complete translucency.
- This is understood to mean a light transmittance of greater than 50% in accordance with ECE R43 (9.1), measured in accordance with DIN 5036 and DIN EN 410 for the radiation range of 380-780 nm, based on the standard illuminant D 65 according to DIN 5033, Part 7, and on Sensitivity of the human eye (VI).
- the measurements of the spectral transmittance at normal radiation incidence were carried out with an OMEGA 20 Bruins instrument type spectrophotometer.
- filler materials having different refractive indices such as, for example, fused silica in Example 1 and boron glass in Example 3, do not exhibit any significant different luminances.
- Example 8 In order to investigate whether the shape of the grain has a cause on the luminance, a solid glass sphere Example 8 was used in comparison. Again, there is no significant dependence of the luminance on the shape of the filler grains.
- the photoluminescence decreases at grain sizes with a mean grain size of 30 ⁇ to 70 ⁇ and with a grain diameter greater than 1, 2 mm in turn. Furthermore, it was found that different pigment sizes give only relatively small deviations from this rule.
- the desired photoluminescent effect is obtained by adding the photoluminescent luminescent pigment.
- the granules contain fillers u.a. for the following reasons:
- the body color of the granules should appear neutral, in particular white, and for fluorescent materials the slight discoloration may occur in the case of daylight-neutral pigments can also be fixed or the white effect can be used for design purposes.
- Lightfastness in the present case is understood as meaning a lightfastness value according to blue scale according to DIN 53952 of the matrix of greater light fastness 5, preferably greater than 6 or very particularly preferably 7 or greater.
- the granules according to the invention have a certain size adapted to the design or the possibilities in the end product (plates with high strength also allow, for example, larger aggregates).
- the size of the granules preferably moves in the 0.5-20 mm range, in particular up to 6 mm and most preferably between 1 and 3 mm.
- the granules preferably consist of a similar, a related or a compatible formulation compared to the material in which these as
- Additives are to be used later so that they become later
- Each particle or granule particle represents a self-contained system relative to the photoluminescent effect, e.g. a photoluminescent particle with a diameter of 3 mm.
- the granules are used in comparison to the coloring in a much lower percentage of the total weight of the final product.

- the filler has a mosh hardness of less than 4.5 (eg Corian®) or more than 4.5 (eg Engineered Stone). Particularly good results with respect to the luminance are achieved when the fine fraction of the filler has an average particle diameter of 2 to 30 ⁇ , preferably of 2 to 20 ⁇ , in particular between 4 and 14 ⁇ .
- the possibly present coarse fraction of the filler which preferably has a mean grain diameter of between 0.070 and 1.2 mm, in particular between 0.1 and 1.2 mm.
- the filler may be coated with a matrix-adapted adhesion promoter.
- Suitable photoluminescent luminescent pigments are fluorescent and / or phosphorescent or luminescent luminescent pigments. Preferably those which luminesce in the visible range.
- sulfides, aluminates and phosphorus-based pigments are suitable as photoluminescent pigments. Of these, particular preference is given to the strontium aluminates and / or fluoroaluminates and / or zinc sulfides, in particular those doped with Cu, Ag, Mn, Al, Eu and / or Dy.
- the pigment preferably has an average particle size distribution (D50) between 1 ⁇ m and 300 ⁇ m, in particular between 18 and 100 ⁇ m, very particularly preferably between 1 and 80 ⁇ m.

- the granules take on the role of so-called “aggregates” or “aggregates” which in their natural form, e.g. as quartz or spNt, concrete goods are added.
- Photoluminescent granules may be interspersed or blended equivalent to the aggregates in the manufacturing process.
- Many concrete products are surface treated after production (grinding, shot peening, etc.). This surface treatment additionally liberates the granules and thus allows a good effect of the effect.

- the production is fresh in fresh. If aggregates of about the same thickness are used at a certain layer thickness of the facing concrete, they are located on the one side on the surface. After-treatments such as e.g. Grinding or shot peening releases these additives more and more. It is recommended white Portland cement. In the field of concrete products, the coefficient of thermal expansion must be adjusted accordingly by the fillers / binder.
- the granules of the invention are e.g. as well as litter in
- a granulate with a density close to the resin objects can be cast with photoluminescent granules evenly distributed in the object. Adjusting the density is easily possible by using fillers of different densities, such as hollow glass spheres with low density. Depending on the requirement or desired effect, the density can be adjusted so that an intentional sinking or floating of the granules takes place in the resin.
