Definitions

  • the present invention concerns a method for producing polymer granulate with high concentration of pigments and/or additives as indicated in the preamble of claim 1.
  • the object of the invention is to indicate a method of the kind mentioned in the introduction which enables attaining a hitherto unknown high pigment concentration in monocomponents as well as in masterbatch, in practice resulting in very significant economic advantages as well as advantages in use.
  • the method according to the invention is peculiar in that a low viscosity polymer carrier in the shape of polybutylene (C ) or polypentene (C 5 ) is mixed with one or more pigments and/or one or more additives, possibly together with an auxiliary carrier, and is concentrated up to a pigment/additive content of 75 - 90 %, and that the mixture is melted and processed to become a granulate.
  • a low viscosity polymer carrier in the shape of polybutylene (C ) or polypentene (C 5 ) is mixed with one or more pigments and/or one or more additives, possibly together with an auxiliary carrier, and is concentrated up to a pigment/additive content of 75 - 90 %, and that the mixture is melted and processed to become a granulate.
  • polybutylene (C 4 ) or polypentene (C 5 ) as carrier, possibly in combination with one or more auxiliary wetting agents, it becomes possible to concentrate the pig- ment content considerably and at the same time to achieve a melt that can be made a granulate.
  • the final degree of concentration depends on the "oil number" of each pigment (need for wetting agent).
  • the advantage of concentrating the pigment content is that there is e.g. room for additives in a masterbatch whether this is produced directly or produced from monocomponents by the method according to the invention. Furthermore, a minimizing of the wax content in the masterbatch is achieved so that some of the negative effects by high wax concentration, e.g. "nozzle sauce” and deposits, may be avoided.
  • a recommended dosage of 1-2% is expected by a combination masterbatch compared with one of the leading producers in the word in this area recommending a dosage of about 6 %.
  • polybutylene (C 4 ) or polypentene (C 5 ) as polymer carrier.
  • the melting of the mixture occurs by extrusion, preferably by means of a double screw extruder having great capacity compared to invest- ment in equipment.
  • a low viscosity wax e.g. an oxidised polyethylene wax
  • a filler with a high melting point e.g. calcium carbonate (chalk) or glass (Wollastonite), i.e. a filler which is not dissolved in the melt by the extrusion but makes cheaper or imparts higher pressure strength, respectively, to the material.
  • additives with low melting point e.g. Chimasorb 81 (UN-absorber) or Dehydat 8312 (antistatic), may be applied, i.e. additives which are dissolved in the melt by the extrusion.
  • the method according to the invention may be further modified by the making of a combined masterbatch, e.g. for dyeing a TPU (thermo polyurethane), besides a polymer carrier there are used additives in the form of a laser contrast agent (e.g. Iriodin 25) and a release agent (e.g. Abrilube 77).
  • a laser contrast agent e.g. Iriodin 25
  • a release agent e.g. Abrilube 77
  • a further modification of the method according to the invention may consist in that for making a combined masterbatch, besides a polymer carrier there are used a UV- absorber (e.g. Chimasorb 81), an antistatic agent (e.g. Dehydat 831) and a flame retar- dant (e.g. Apymag AOH 850), i.e. the finished plastic mass is supplied with additives with specific material properties besides colour pigment.
  • a UV- absorber e.g. Chimasorb 81
  • an antistatic agent e.g. Dehydat 831
  • a flame retar- dant e.g. Apymag AOH 850
  • Example la organic pigment
  • auxiliary wetting agent e.g. an oxidised polyethylene wax (Vestowax C 60) are mixed, melted and made to granulate.
  • auxiliary wetting agent e.g. an oxidised polyethylene wax (Vestowax C 60)
  • C polymer carrier polybutylene
  • C 5 polypentene
  • auxiliary wetting agent e.g. an oxidised polyethylene wax (Vestowax C 60)
  • Example 3 a (fillers) 10% polymer carrier polybutylene (C 4 ) or polypentene (C s ), e.g. Vestowax B 912,
  • Example 4a (fluid additives)
  • C 4 polymer carrier polybutylene
  • C 5 polypentene
  • Abrilube 77 release agent
  • Iriodin 825 laser contrast agent
  • polymer carrier polybutylene C 4
  • polypentene C 5
  • Vestowax B 912 1,5% Chimasorb 81 (UV absorber), 5% Dehydat 8312 (antistatic) and 82,5% Apymag AOH 850 (flame retardant) are mixed, melted and made to granulate.
  • the indicated polymer carrier besides its ability to wet the pigment optimally, is furthermore advantageous in that the melt with the pigment is so suited for being extruded, i.e. it is "coherent” (plastic) and workable at a suitable temperature and hard when cooled whereby it becomes possible to extrude it to granulate.

Abstract

L'invention porte sur un procédé servant à produire des granulats polymères à concentration élevée de pigments et/ou d'adjuvants, de préférence sous la forme d'un seul composant à base de cire ou d'un mélange maître contenant un ou plusieurs pigments et/ou adjuvants. Ce procédé consiste à mélanger un support polymère à faible viscosité un ou plusieurs pigments et/ou un ou plusieurs adjuvants, si possible avec un support auxiliaire, et à le concentrer jusqu'à l'obtention d'une teneur en pigments/adjuvants comprise entre 75 et 90 %. Il consiste ensuite à faire fondre ce mélange et à le transformer en granulat. L'utilisation du polybutylène (C>4<) ou du polypentène (C>5<) en tant que support, si possible en combinaison avec un ou plusieurs agents mouillants auxiliaires, permet de concentrer sensiblement la teneur en pigments et, parallèlement, d'obtenir une matière fondue qui pourra être transformer.
