Definitions

  • the filter pressure that builds up when the pigment-containing melt is filtered and colohmetric measurement data can be used as a measure of the quality of the dispersion.
  • DE 42 36 337 A1 describes the use of polymers of acrylic acid -C 2 -C 22 alkyl esters as dispersing agents for solids in organic media.
  • DE 195 16 387 A1 claims dispersants for pigment concentrates consisting of a largely amorphous poly- ⁇ -olefin, a polyolefin wax, a crystalline polyolefin and a polyacrylic ester.
  • pigment concentrates which contain copolymers consisting of a), b) and c).
  • the ⁇ -olefins are preferably in the chain length range Ci 8 - to C ⁇ o-
  • the pigment concentrates particularly preferably contain 5 to 40% by weight of copolymer, 20 to 50% by weight of pigment and 10 to 50% by weight of polyolefin.
  • Suitable ⁇ -olefins are those with a chain length of 12 to 60, preferably 18 to 60, particularly preferably 26 to 60 carbon atoms. Both chain-pure olefins and olefin mixtures can be used, e.g. incurred in the known manufacturing processes as distillation cuts or distillation residues.
  • Technical ⁇ -olefin mixtures especially those with a longer chain length, can contain, in addition to 1-alkenes, more or less high amounts of internal and lateral olefinic double bonds (vinylene and vinylidene groups), and also proportions of saturated non-olefinic hydrocarbons.
  • the copolymers are prepared in a manner known per se by copolymerizing the monomers in the presence of free radical initiators. Corresponding procedures are described, for example, in DE 41 39 601 A1. All pigments that are used for coloring plastics are suitable for the production of the pigment concentrate. Examples can be found in relevant standard works such as Herbst, Hunger, Industrielle organic Pigments, 2nd ed. 1995, pages 4-11. Both inorganic and organic pigments can be used. Carbon black, titanium dioxide, zinc oxide and iron oxides may be mentioned as examples of inorganic pigments. Examples of organic pigments are azo, quinacridone and phthalocyanine pigments.
  • the pigment concentrate it has proven useful to first premix the solid individual components in suitable mixing units.
  • Copolyamate and optionally waxes can be used in coarse to fine-particle or micronized form, for example with average particle sizes (d50 values)> 4 ⁇ m.
  • the actual pigment dispersion is then carried out by melting and kneading the premix in a kneader or extruder. Examples
  • Acid and saponification numbers or dropping points were determined in accordance with DIN standards 53402, 53401 and 51801.
  • the melt viscosities were measured using a rotary viscometer in accordance with the M-Ill 8 standard of the German Society for Fat Science.
  • the copolymers listed in Table 1 were ground ( ⁇ 2 mm) and in a Henschel mixer with the pigment and with polypropylene plastic mixed (room temperature, 600 rpm, 10 min). The mixture was then processed into granules in a twin-screw extruder (Berstorff ZE 25x40 D).

Abstract

L'invention concerne des concentrés pigmentaires pour la coloration de plastiques thermoplastiques. Ces concentrés pigmentaires sont caractérisés en ce qu'ils contiennent des copolymères constitués a) d'unités dérivées d' alpha -oléfines de la longueur de chaîne C12-C6o et éventuellement b) d'unités dérivées d'un acide carboxylique de formule CH2=CR<1>-COOH et/ou c) d'unités dérivées d'un ester d'acide carboxylique de formule CH2=CR<1>-COOR<2> et/ou d) d'unités dérivées de styrène, 3-méthylstyrène, 4-méthylstyrène ou alpha -méthylstyrène, R<1> représentant un atome d'hydrogène ou un groupe méthyle et R<2> représentant un reste alkyle linéaire ou ramifié ayant 1 à 6 atomes de carbone.
