Definitions
- the invention relates to a transparent zinc sulfide of high specific surface area, a process for its preparation and the use of this zinc sulfide.
- the high reflectance of the 300 nm particles in the visible light and near UV range results in a neutral white tone as well as optimal scattering, capping and whitening power when used in coatings and plastics.
- Due to the white pigment properties zinc sulfide is used where organic or inorganic binders must be highly pigmented for specific applications, for example in precursors, jointing and sealing compounds, primers, etc.
- plastics are pigmented with zinc sulfide, for example melamine, urea and polyester molding compounds. whereby these can be dyed excellent. In addition, other properties such as increased flame retardancy are achieved.
- Zinc sulfide Due to the relatively low Mohs hardness of 3 and the spherical grain shape, zinc sulfide has a very low abrasiveness and therefore does not cause metal abrasion during processing.
- Zinc sulfide is widely used as a white pigment, especially in fiber-reinforced plastics, because the titanium dioxide used alternatively as a white pigment, because of its higher Mohs hardness of 5.5 to 6.5 unlike zinc sulfide leads to breakage of the glass fibers.
- EP-B-1463411 discloses the use of zinc sulfide as an anti-mite agent in threads, fibers, filaments. Also disclosed is the use of zinc sulfide in a liquid or solid composition for the cleaning and / or treatment of textile surfaces.
- K ⁇ ausland ⁇ OZ06095 doc DE-A-10051578 discloses a process for producing yarns, fibers or filaments having significantly better whiteness and less yellowing.
- the process comprises mixing a masterbatch of zinc sulfide and polyester in the melt and then spinning it from the melt.
- the zinc sulfide is used in a proportion of 0.1 to 3 wt .-% as a white pigment for matting the polyester fiber products.
- the typical particle size of the zinc sulfides used as white pigment is approximately 300 nm, the specific surface area (BET) is 2 to 10 nrvVg and shows a relative whitening capacity of about 380 (DIN 55982).
- this zinc sulfide is not transparent in the visible range. Therefore, it has not hitherto been suitable as an additive in applications in which transparency or color retention are desired, so that hitherto other substances have to be used. However, these do not have the low Mohs hardness and biocidal properties of zinc sulfide, e.g. against mites.
- the object of the invention is to provide a zinc sulfide, which is transparent on the one hand, that is, in which the white pigment properties are reduced or completely absent, on the other hand has the desired low Mohs hardness and desired biocidal properties.
- the object is achieved by the zinc sulfide according to the invention.
- this object is achieved by a finely divided, that is nanoscale, zinc sulfide having a mean crystallite size of less than 250 nm, preferably less than 150 nm, more preferably less than 80 nm, most preferably less than 40 nm.
- the zinc sulfide according to the invention has an extremely low scattering and whitening power with a value less than 300 (DIN 55982) preferably less than
- K ⁇ ausland ⁇ OZ06095 doc 100 more preferably less than 70, so that no hiding power is achieved during incorporation, for example in moldings and coatings.
- the specific surface area (BET, determined according to DIN-ISO 9277) is 15 to 300 nrvVg, preferably 30 to 250 m 2 / g, particularly preferably 50 to 200 m 2 / g.
- the zinc sulfide of the invention has reduced or absent white pigment properties. It has a low Mohs hardness and is biocidal, especially against algae, fungi and bacteria.
- the zinc sulfide of the present invention is prepared by combining a compound containing sulfide sulfur with a solution containing a zinc compound to precipitate zinc sulfide as a solid. This solid is optionally isolated by washing, filtration and subsequent drying.
- the zinc sulfide according to the invention is prepared, for example, by mixing the aqueous solution of a sulfide-containing compound in an appropriate concentration, at a suitable temperature, with an aqueous solution containing a zinc compound, the mixing being controlled so that a certain pH Value, preferably a pH of 5, more preferably from 3 to 4, is not exceeded and, after precipitation of the zinc sulfide, the pH of the suspension is adjusted to a value of about 7 by further addition of aqueous solution of the sulfide-containing compound with stirring , the obtained zinc sulfide is filtered, washed to the required salt clearance, dried and optionally ground.
- a certain pH Value preferably a pH of 5, more preferably from 3 to 4
- sulfide sulfur-containing compounds for example, metal sulfides and / or metal polysulfides are used, preferably those of the alkali group.
- Gaseous hydrogen sulfide (H 2 S) can also be used according to the invention, the H 2 S being introduced into the solution of the zinc compound.
- organic sulfide sulfur such as thioacetamide, for
- zinc compounds for the precipitation of feinstteiligem zinc sulfide is preferably zinc sulfate and / or zinc chloride and / or an organozinc compound, such as zinc acetate, used. Also mixtures of these zinc compounds are possible.
- the solutions may be combined in any combination and order.
- the precipitation can take place in one or more stages, preferably in two stages.
- the primary particle size can be controlled, for example, via the variation of the educt solutions or their concentrations, the variation of the temperature or the variation of the residence times.
- a precipitation in the autoclave results in a variety of process parameter combinations, via which the desired particle size can be set.
- the zinc sulfide suspension thus obtained is then worked up to the finished product by methods known in the art. Usually, the suspension is then filtered and washed free of salt depending on the requirements of the product, dried and ground as needed.
- K ⁇ ausland ⁇ OZ06095 doc The drying can be done for example in a rotary kiln, a spray drier, a hearth furnace, but also by freeze-drying. Likewise, the removal of water is possible using the technique of flushing.
- the dried product can be micronized, for example, in a pencil, a Coloplex, a Zirkoplex, a steam or air jet mill.
- the zinc sulfide according to the invention can be provided for the various applications after working up the precipitation suspension according to the prior art as fine particulate suspensions, as a slurry, as a paste or powder after drying and optionally grinding.
- the primary crystallite size of the zinc sulfide according to the invention is less than 250 nm, preferably less than 150 nm, more preferably less than 80 nm, most preferably less than 40 nm.
- the zinc sulfide nanoparticles according to the invention have greatly changed and have new product properties, it is particularly preferred according to the invention that the individual particles are not agglomerated so that they optimally distribute themselves during processing for the various applications.
- the zinc sulfide according to the invention can be aftertreated inorganically and / or organically, as is customary, for example, in the known titanium dioxide pigments and as described, for example, in the following documents: EP 1 576 061 A2, US Pat. No. 4,052,224 A1, US Pat. No. 3,941, 603 A1 and US Pat US 4,075,031 A1.
