Definitions
- the invention relates to a catalytically degradable plastic, in particular with a content of cellulose esters and the use thereof, in particular in filter tows for the production of filter plugs of filter cigarettes.
- Plastics that may or may end up in the environment at the end of their lifecycle should be degradable within a short period of time under the conditions prevailing there in order to minimize exposure to pollution.
- the duration of their decomposition depends strongly on the external conditions. So the degradation under composting conditions is faster than in likewise
- Anatase modification which can decompose organic materials by photocatalytic action. Anatase absorbs light in the ultraviolet range of the
- the present invention seeks to provide further under catalytically degradable plastics under environmental conditions.
- this catalytically degradable plastic is to find advantageous application as a shaped body, in particular in a filter tow for producing a filter plug of a cigarette filter.
- this object is achieved by a catalytically degradable plastic of the type described above in that the catalytically degradable plastic contains a catalytically active transition-metal-modified titanium dioxide, especially in finely divided form, e.g. dispersed in the plastic.
- transition metal-modified means, in particular, that the titanium dioxide is oxidized by addition, (for example, mixing,
- Impregnation, co-precipitation, co-crystallization of metals, metal compounds or metal complexes of the transition metals.
- Transition metals are metals of Groups 3 to 12 of the Periodic Table (IUPAC, 2013), with the exception of titanium such as chromium, cobalt, copper, nickel, silver, gold, vanadium, zirconium, tungsten, molybdenum, tantalum, niobium, manganese, Zinc and iron. Preference is given to non or low toxic
- Transition metals in particular manganese, zinc and iron. Iron is especially preferred.
- Specific suitable iron-modified titanium oxides containing ferric oxide have been disclosed in WO-A-2012/139726, the contents of which are incorporated by reference into the present application.
- the modification of the titanium dioxide with transition metals leads to an improvement in the catalytic activity for the degradation of plastics without the performance characteristics of the
- plastic is a cellulose ester, cellulose acetate,
- Degree of substitution is preferably between 1.5 and 3.0, in particular between 2.2 and 2.7, especially in the case of cellulose acetate. It is expedient if the cellulose ester, in particular cellulose acetate, with respect to an advantageous degree of polymerization with respect to the average degree of polymerization Solution of the task is optimized. The optimum average degree of polymerization is between 150 and 500, in particular between 180 and 280 in the cellulosic ester.
- Cellulo starter compositions can be catalytically degraded at high speed in the environment.
- a suitable measure is, like the
- the core of the invention thus lies in the selection of a transition-metal-modified titanium dioxide, which is transition-metal-modified on its surface or else in the entire volume. Preference is given to a transition-metal-modified titanium dioxide whose surface is transition-metal-doped. By doping the band gap of the semiconductor titanium dioxide is reduced and it can be used in comparison to undoped titanium dioxide and longer wavelength light for exciting a valence band electron and thus to activate the photocatalytic properties.
- the crystallite size of the transition metal-doped titanium dioxide is expediently optimized, the crystallite size preferably being between 5 and 150 nm, in particular between 7 and 25 nm. In individual cases, it may be advantageous or even necessary, a coarse
- Transition metal modified titanium dioxide to grind to the optimum
- transition metal modified titanium dioxide has a density (ISO 787, Part 10) of 3.0 to 5.0 g / cm 3 , in particular from 3.5 to 4.2 g / cm 3 .
- An advantageous effect also for a degradation of the cellulose ester-containing plastic is an optimization of the specific surface of the transition metal-modified
- Titanium dioxide It is preferable that the BET specific surface area of the transition metal-doped titanium dioxide is greater than 100 m2 / g, in particular greater than 250 m 2 / g.
- the inclusion of a transition-metal-modified titanium dioxide in the catalytically degradable plastic according to the invention has a particularly advantageous effect if the
- Transition-metal-modified titanium dioxide is characterized with a compared to pure titanium dioxide increased light absorption in the range of ⁇ > 400 nm.
- transition-metal-modified titanium dioxide to 0.1 to 5% by weight, in particular 0.3 to 1.5% by weight.
- the transition metal content of the transition metal-modified titanium dioxide is not significantly limited. Preferably contains
- transition metal-modified titanium dioxide transition metal in an amount of 0.05 to 5% by weight, in particular from 0.3 to 3% by weight.
- the catalytically degradable plastic is essentially not based solely on cellulose esters.
- Conventional additives such as e.g. Plasticizers, be included, so in the case of
- a non-transition-metal-modified titanium dioxide in particular anatase, may be included in fine dispersion, especially in the case of the cigarette industry.
- the content of the catalytically degradable plastic of cellulose ester is at least 60% by weight, in particular at least 90% by weight ,
- the good catalytic degradability of the plastic according to the invention in particular, when the catalytically degradable plastic is converted into a shaped body, especially in fibers, films, especially deep-drawn films, especially for use as packaging materials, injection molded articles, thick-walled moldings, granules, microbeads , Pearls and vessels. Therefore, the further processing of these fibers into filter tows, with which filter rods and filter caps of
- Filter cigarettes are produced. Such filter plugs found in the environment are degraded significantly faster than those containing unmodified titanium dioxide.
- the method for producing the catalytically degradable plastic according to the invention is not particularly limited.
- One possibility is the
- the plastic in particular cellulose ester
- the plastic is preferably dissolved in the customary manner, for example in acetone.
- the relevant other ingredients such as the particular Transition metal modified titanium dioxide added to then perform the usual spinning in a drying channel.
- Another embodiment of the dry-spinning process envisages mixing the relevant further constituents-apart from the plastic, in particular cellulose ester-in particular the transition metal-modified titanium dioxide, with a suitable solvent, for example acetone, and then adding the plastic, in particular cellulose ester. This mixture is then used in a drying channel for the usual spinning process.
- Iron-modified TiO 2 is used according to the method disclosed in Example 1 of WO 2010/017989 in the production of a cellulose acetate-based filter rod.
- the filter rod of the present invention exhibits improved degradability under environmental conditions compared to a filter rod made with unmodified TiO 2.
