Definitions
- the invention relates to platelet-shaped pigments which are doped with metal oxide particles, have high opacity and improved gloss.
- Platelet-shaped pigments which, in addition to having a high gloss, have satisfactory interference and have sufficient hiding power, are often very difficult to produce. Especially in the manufacture of colored platelet-shaped pigments, which are usually caused by
- platelet-shaped substrates which are covered with one or more metal oxide layers are distinguished by interference and gloss, but have an insufficient covering power due to the transparent material.
- the hiding power can be increased by the deposition of relatively rough metal oxide layers, but the gloss decreases drastically.
- the use of metal substrates as platelet-shaped carrier materials also leads to a high
- the object of the present invention was to provide new pigments with favorable properties which in particular meet the aforementioned requirements and also represent valuable materials for technical use.
- a platelet-shaped pigment with a higher gloss and an improved hiding power can be produced compared to pigments which are obtained by conventional mixed precipitation will .
- the invention thus relates to platelet-shaped pigments with high gloss and high hiding power, consisting of a platelet-shaped carrier material which is covered by an inorganic matrix in which metal oxide and / or dye particles are contained in the submicron range, the coating being highly homogeneous .
- the invention also relates to a process for the production of platelet-shaped pigments with improved gloss and hiding power, platelet-shaped substrates in aqueous suspension being coated with a metal oxide or metal oxide hydrate layer by hydrolysis of metal salts and then separated, optionally washed, dried and annealed, characterized in that
- the particles have a size in the submicrometer range.
- the invention also relates to modified processes for the preparation of the pigments according to the invention and to the use thereof.
- the pigments according to the invention consist of a platelet-shaped inorganic carrier material, such as, for example, glass, kaolin, muscovite, ilmenite or particularly preferably mica.
- This platelet-shaped material is formed by precipitation with a metal hydroxide layer, in which
- Metal oxide and / or organic dye particles are incorporated, coated, but the metal oxide and / or organic dye particles are entrained when the hydroxide layer is deposited and there is no mixed precipitation in the conventional sense.
- the platelet-shaped substrates preferably have a thickness between 0.1 and 5 ⁇ m, but in particular between 0.2 and 4.5 ⁇ m.
- the linear expansion in the other two dimensions is usually between 1 and 250 ⁇ m, particularly preferably between 2 and 200 ⁇ m.
- Suitable matrix oxides are, for example, silicon dioxide, silicates, boron trioxide, borates, aluminum oxide, aluminates or particularly preferably titanium dioxide, and also all other materials known per se in the production of platelet-shaped pearl and colored gloss pigments.
- soluble metal salts preferably from halides, sulfates or nitrates, particularly preferably from chlorides, by hydrolysis at appropriate pH values.
- the metal oxide and / or organic dye particles embedded in the matrix have a size of 10-40 nm. They are therefore significantly smaller than the platelet-shaped pigment or as the metal oxides produced by mixed precipitation and are entrained and precipitated when the matrix oxide is precipitated the interstices of the matrix pack are built in, as a result of which a higher pack density and associated higher opacity and a higher gloss are produced.
- the metal oxide and / or organic dye particles are generally randomly incorporated and preferably of amorphous or spherical shape.
- Suitable metal oxide particles are all known stable inorganic oxides which do not react with the precursor materials of the matrix in the production of the pigments according to the invention.
- the metal oxide particles can be colorless or colored and are preferably pure
- organic pigment particles In addition to inorganic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles, organic pigment particles
- Pigment particles are used, in particular temperature-stable organic pigments being preferred. In many cases, the manufacturing conditions of the invention
- Pigments e.g. can be varied by reducing the drying and, if appropriate, annealing temperature while increasing the drying or annealing time or also by other measures such that less stable organic pigment particles can also be used. In addition, it is frequently observed that
- organic pigment particles phthalocyanines, varnish products of basic dyes with heteropolyacids, anthroquinones, phenazines, phenoxazines, diketopyrrolopyrroles or perylenes.
- the pigment particles listed here are also known, as are processes for their preparation (see, for example, H. Kittel,ticianliche Verlagsgesellschaft, Stuttgart 1960, G. Benzig, pigments for paints, Expert Verlag 1988) and they are generally commercially available. However, these pigment particles are only to be understood as examples, and are only intended to illustrate the invention without limiting it in any way. In addition to the pigment particles explicitly mentioned, a large number of further pigment particles can be used.
- wetting agents to the precursor solution for better dispersion of the pigment particles, e.g. non-ionic or ionic commercial types.
- non-ionic or ionic commercial types e.g. Polyethylene and polypropylene glycols are well suited.
- the type nor the amount of the wetting agent added are critical, but in general the proportion of the wetting agent is at most 2% by weight, based on the dispersion.
- platelet-shaped carrier materials preferably mica
- a titanium salt solution preferably a titanium tetrachloride solution which simultaneously contains TiO 2 particles in the rutile modification.
- These rutile particles are carried away during the precipitation and embedded in the matrix spaces. At the same time, they act as rutilization nuclei and partially rutilize the titanium dioxide coating.
- the mass fraction of the rutile modification in the matrix is usually 0.5 to 40% by weight.
- the rutile particles have an average diameter between 10 and 40 n.
- a platelet-shaped pigment with a high gloss and high hiding power is formed, the proportion of the rutile modification being very strongly dependent on the annealing temperature.
- the calcination is preferably carried out at temperatures between 700 and 1000 °, particularly preferably between 800 and 900 °. The use of foreign layers for rutilization, such as Sn0 2, is not required.
- the hiding power and - in the case of colored pigment particles - the observation color-independent absorption color of the pigments according to the invention can be varied in a further range by the concentration of the incorporated pigment particles.
- the mass fraction of the pigment particles stored, based on the matrix, is typically between 0.5 and 30% and in particular between 2 and 20%.
- pigments according to the invention with one or more embedded organic and / or in particular inorganic colored pigments; iron oxides, chromium oxides, cobalt oxide and colored spinels such as cobalt aluminum oxide (CoAl 2 0 4 ) are particularly preferably used.
- the pigments according to the invention are thus optical systems with an excellent combination of optical properties, the relative expression of which is also in the
- the pigments according to the invention thus represent a considerable enrichment of the range of pigments which can be used industrially, and they are of considerable economic importance.
- the pigments according to the invention are produced by wet chemical processes, such as those in US 30 87 828, DE 20 09 566, DE 22 14 545, DE 25 22 572, DE 25 22 573, DE 31 37 809, DE 31 51 354, DE 31 51 355, DE 32 11 602 or DE 32 35 017 are described and are also used in pigment production by mixed precipitation.
- the procedure is preferably such that an aqueous suspension of a platelet-shaped substrate is prepared and heated to a temperature between 5 and 95 °.
- a suspension of a metal salt is then added in the presence of metal oxide and / or organic dye particles, with a particle size in the submicron range, the particles being finely dispersed or separated either in the substrate suspension or in the metal salt solution be added to the substrate suspension as an aqueous dispersion simultaneously with the metal salt solution.
- the pH of the substrate suspension is kept in a range by simultaneous addition of a base which is suitable for the hydrolysis of the respective metal salt and which causes a corresponding precipitation of the hydroxide.
- the previously added metal oxide and / or organic dye particles are entrained and stored in the cavities of the striking water-containing oxide layer.
- the coated substrate is separated, washed. dried and then calcined at temperatures between 400 and 1200 °, preferably at 600 to 1000 °.
- the procedure can also be such that a suspension comprising the substrate to be coated, the submicron particles to be incorporated and the metal salt is prepared and the hydrolysis of the metal salt is then effected by heating and / or adding a base.
- Composition of the pigment 51% mica, 1% Sn0 2 , 6% Aerosil 200®, approx. 42% Ti0 2 .
- Example 3 Analogously to Example 1, instead of 6% Aerosil 200® 12% are dropped into the Ti0 2 layer.
- the composition of the pigment is: 44% mica, 1% Sn0 2 , 12% Aercsii 200®, approx. 43% Ti0 2 .
