Definitions
- the invention relates to the use of a zinc oxide (ZnO) -containing frit as UV protection agent (or UV protection pigment), e.g. acid-stable and at the same time (photo) catalytically inert UV protective agent / pigment, in a carrier material, e.g. in plastic and paint systems.
- a zinc oxide (ZnO) -containing frit as UV protection agent (or UV protection pigment), e.g. acid-stable and at the same time (photo) catalytically inert UV protective agent / pigment, in a carrier material, e.g. in plastic and paint systems.
- thermoplastic or thermosetting plastics are currently organic and inorganic UV protection agents in use.
- the UV protection agent has the task in particular of plastic or painted surfaces against the decomposition by UV radiation in
- Suitable organic UV protection agents are UV absorbers, quenchers and HALS.
- UV absorbers are primarily hydroxyphenylbenzotriazoles and
- Hydroxybenzophenones used. Quenchers mainly work with nickel chelates. Similar to UV absorbers, short-wave UV radiation is converted into long-wave, low-energy radiation.
- the group of HALS (hindered amine light stabilizer) systems consists of monomeric, oligomeric and polymeric amine compounds which deactivate the radicals resulting from UV radiation and thus contribute to improved UV stability on the plastic or painted surface.
- HALS hinderedered amine light stabilizer
- organic UV absorbers is controversial due to the lack of effectiveness or limited due to the high cost of low use concentrations.
- Inorganic chemistry provides a variety of UV protectants that can be divided into colored or black UV absorbers and transparent or opaque UV absorbers.
- the group of rutile mixed phase pigments such as e.g. Sb- and Ni-doped titanium dioxides, among the colored UV absorbers and carbon black, are among the black UV absorbers.
- the focus of the present invention is on the inorganic UV absorbers, in particular on the transparent, colorless and opaque inorganic UV absorbers.
- Ti0 2 titanium dioxide
- Ti0 2 is mostly used as a coated Ti0 2 pigment with a rutile structure.
- the coating of the Ti0 2 often consists of a thin Si and / or Al-containing inorganic layer and serves to protect the surrounding matrix from the photocatalytic decomposition, which is characteristic of uncoated Ti0 2 with anatase and rutile structure.
- the TiO 2 is doped in the core with zirconium. Ti0 2 absorbs well in the UV-B wavelength range (315 to 280 nm) and in UV-A Wavelength range (380 to 315 nm) still good.
- the disadvantage of using Ti0 2 is that the surfaces of the Ti0 2 pigment particles are not covered to 100% by the coating and thus a photocatalytically induced radical attack on the surrounding matrix of Ti0 2 particles under UV irradiation and simultaneous influence of moisture he follows.
- surrounding matrix or binder matrix is meant the immediate environment to be protected of UV absorbers or UV protective pigments.
- the Ti0 2 surrounding matrix is decomposed by the photocatalytic effect of the incompletely coated Ti0 2 , resulting in a microporous, rough surface structure in the binder matrix, which simulates a color intensity change, especially in dark shades. Due to the destroyed microporous structure, the incident light is scattered more strongly than on a smooth surface. The surface looks dull and lightened. This color intensity change is also called chalking or chalking.
- Ti0 2 is used as UV protection pigment or UV absorber preferably for light and opaque (opaque) plastic and paint systems. In the case of dark shades, the opaque Ti0 2 pigment is present at the same time
- Ti0 2 has a turbid effect, so that the use of Ti0 2 as UV protection pigment is unsuitable for this purpose.
- ZnO is suitable as UV protection pigment / protective agent.
- ZnO has better UV absorption than Ti0 2 , especially in the UV-A wavelength range (380 to 315 nm).
- the main disadvantage of ZnO is the good solubility in acids.
- HCI vapor is released, which with ZnO to ZnC! 2 reacts.
- the resulting ZnCl 2 in turn, is hygroscopic and, more unfavorably, it catalyzes the thermal decomposition of PVC.
- Pure ZnO also shows photocatalytic radical formation, although this is less pronounced than that of pure rutile.
- the refractive index of ZnO is 2.0, so that a plastic matrix (refractive index: 1.4 to 1.6) can be over-dyed to a strong dark color system with a relatively low color pigment loading.
- WO 90/06974 describes the use of water-glass-coated ZnO pigments for use as acid-resistant UV protection for plastics. This is a silicate coating that envelops the ZnO core material so that there is an inhomogeneous distribution of ZnO and silicate component.
- From DE 1 496 646 A is for the use of plastics Zr0 2 u./od. Ti0 2 -containing, finely ground F ritte described that may contain up to 15 wt.% ZnO.
- the object of this invention is to keep the opacity or whiteness high despite the silicate dilution.
- Glass frits of similar composition are e.g. from EP 1 870 383 A1, EP 1 298 099 A1, US Pat. No. 5 618 764 and US Pat. No. 4,493,900. However, these known frits are not yet used as a UV protective pigment.
- a frit is understood to mean an already solidified and re-ground glass melt which, in addition to amorphous portions, may also have crystalline components.
- the frit according to the invention may consist of network formers, such as Si0 2 or B 2 0 3 , network converters, such as Alkalioder Erdalkalioxiden, and ZnO and optionally intermediate oxides, such as Al 2 0 3 (which can act both as a network converter and as a network former).
- network formers such as Si0 2 or B 2 0 3
- network converters such as Alkalioder Erdalkalioxiden
- ZnO optionally intermediate oxides, such as Al 2 0 3 (which can act both as a network converter and as a network former).
- opacifiers such as, for example, TiO 2) SnO 2 , ZrO 2 , CeO 2 and Ca 3 (PO 4 ) 2 and NasAIFs are used for the preparation of att f rs.
- the opacifiers are
- oxides or mixed oxides can be crystallized out of the amorphous glass phase.
- a UV protecting agent e.g., UV protecting pigment
- a UV absorber for protecting the surrounding matrix from destructive UV radiation, e.g. for use in a thermoplastic or thermoset plastic.
- the invention provides a use of a ZnO-containing frit as in claim 1
- Claim 12 describes the advantageous use of the frit in PVC, or the resulting PVC plastic, in which the frit is distributed.
- the inventor has found a solution for incorporating ZnO as chemically and mechanically stable UV light-absorbing protective agent / pigment into a binder matrix of, for example, thermoplastic or thermosetting plastic. Surprisingly, it has been found that ZnO bonded in a frit has excellent absorption of UV light and at the same time shows resistance to acid and abrasion as well as photocatalytically inert to the surrounding matrix.
- the ZnO lies in the frit crystalline and / or as
- opacifiers from the oxides of the group Ti0 2 , Sn0 2 and Zr0 2 , Ce0 2 and Ca 3 (P0 4 ) 2 and Na 3 AlF 6
- the ZnO concentration in the frit may be e.g. more than 30% by weight, e.g. more than 50% by weight.
- ZnO-containing frit protects the surrounding matrix by the radiated high-energy UV light from the ZnO-containing frit is mainly absorbed and converted into longer-wave heat radiation and emitted.
- the proportion of UV light reflected or scattered on the ZnO-containing frit is preferably low, so that no additional
- UV light is also preferably low.
- the absorption effect is achieved on the one hand by ZnO in its function as a network converter, the silicate scaffold interrupts so strong that compared to normal borosilicate or soda lime glasses, a shift of the UV absorption takes place at higher wavelength ranges.
- undissolved or recrystallized ZnO particles in the glass phase absorb UV light due to the semiconducting nature of ZnO. Although any scattering of the UV light on the crystallized ZnO particles will cloud the frit, it does not contribute to the protection of the surrounding matrix.
- the ZnO-containing frit When incorporated into PVC, the ZnO-containing frit has a comparatively significantly lower tendency to chalk than, for example, pure ZnO or compared to different grades of coated TiO 2 and BaS0 4 or other zirconium-containing frits.
- the preparation of the ZnO-containing frit can be carried out according to known methods by mixing and melting mainly oxidic or siliceous raw materials and subsequent cooling and grinding of the frozen melt. Furthermore, an additional annealing process can follow or be interposed, with the aim of recrystallizing ZnO
- the preferred average crystallite size of the recrystallized or unresolved ZnO particles in the frit is e.g. at less than 300 nm, e.g. at less than 100 nm.
- the resulting mean grain size of the frit after milling, based on particle number, should be less than 30 ⁇ m, e.g. less than 5 ⁇ and e.g. be less than 1 m.

- the optional annealing is e.g. at temperatures from 400 ° C to 900 ° C. To illustrate the frit, e.g.
- ZnO grades are used which contain at most 1% by weight impurities and have a sieve residue of less than 0.05% by weight with a sieve mesh size of 42 ⁇ m.
- the qualities are also known by the product names red seal, green seal and white seal.

- the color of the frit is e.g. white or colorless, depending on the system in which the consideration takes place. In air, the color is e.g. white, with a whiteness of more than 90% in the CieL * a * b measuring system is sought. Both the a value (yellow-blue axis) and the b value (green-red axis) are preferably between -4 and +4 points.
- the frit is incorporated, for example, in the plastic PVC, the whiteness decreases sharply in comparison to the observation in air and the overall system of PVC and ZnO-containing frit appears almost transparent.
- the reason lies in the refractive indices of PVC and ZnO-containing frit.
- the refractive index of the ZnO-containing frit is between 1, 4 and 2.6, for example between 1, 5 and 2.0.
- the plastic or lacquer matrix usually has a refractive index of 1.4 to 1.6.
- the overall system of ZnO-thick grains and plastic or lacquer matrix is transparent when the two refractive indices are the same and slightly opaque when the refractive index of the ZnO-containing frit is higher than the refractive index of the surrounding plastic matrix.

- the ZnO-containing frit can be used alone or in combination with conventional organic or inorganic pigments and can also be mixed with colorants and fillers and a wide variety of plastic stabilizers or solvents.
- the ZnO-containing frit can be mixed with Ti0 2 , whereby a UV broadband filter for the UV-A and UV-B radiation can be generated. A restriction to a certain mixing ratio does not exist.
- Plastic stabilizers in the case of plastic PVC include the additives required for thermoplastic shaping, such as thermal stabilizers, for example.
- Plasticizers, acid scavengers, lubricants and antioxidants to understand and with fillers are calcite, barite, talc or kaolin meant.
- Copper phthalocyanines, quinacridones, pyrrolpyrroles, isoindolines, perylenes and the azo pigments, e.g. Diaryl yellow and benzimidazolones are typical representatives of organic pigments.
- the most important representatives of the inorganic pigments are iron oxides, rutile mixed-phase pigments, carbon black, ultramarines, chrome oxide green and a wide range of mixed oxide pigments.

- the ZnO-containing frit can be incorporated directly into the target application range as a powder component or as a mixture with other substances or as a concentrate in the form of a so-called masterbatch.
- a masterbatch is a premix or (color) concentrate, consisting in Substantially from 40 to 90% by weight of a pigment or a pigment mixture and 60 to 10% by weight of a plastic and / or wax mixture or a solvent comprising water and organic solvents.
