Definitions

  • the present invention relates to the preparation of highly charged lubricant compositions containing low melting or liquid release, lubricating and lubricating agents. These substances significantly affect the quality of the plastics, e.g. Increased transparency, reduced color change, better sliding and increased flexibility.
  • the invention relates to the use of copolymeric low molecular weight waxes for the preparation of such active ingredient compositions in which the waxes are prepared by means of metallocene catalysts having a low dropping point, high transparency and low viscosity.
  • the use of these waxes, the incorporation of lubricants, release agents and lubricants is much easier, the process temperatures can be kept significantly lower, a much higher loading than previously possible is possible and can be dispensed with a polymeric carrier.
  • low and high molecular weight waxes such as. various mineral, silicone, or paraffin oils and lubricants, possible.
  • These may be common mineral oils, but also paraffin oils, which are also used in the production of EPDM (ethylene-propylene-diene rubber).
  • EPDM ethylene-propylene-diene rubber
  • the paraffin oil addition during EPDM production increases the elasticity of the products.
  • the incorporation of higher amounts of erucaamides, erucic acid amides and oleamides, etc. is possible. These products are often used in film processing as antiblocking agents. At masterbatches such high demands are made:
  • the incorporated products should be optimally distributed, they should be present only limited to the surface, so that clumping be avoided, with the highest possible dosage in order to keep the raw material costs as low as possible.
  • active ingredient compositions which contain a high concentration of lubricants, release agents and lubricants
  • the following are currently the following single-stage or multi-stage processes:
  • the waxy / polymeric formulation components are fed via the main feed of the extruder; and lubricants that are powdery or liquid are conveniently introduced via corresponding sidefeeder into the machine. An addition to the main entry is also possible.
  • a melt mixture can be carried out in a suitable extruder or in kneaders. This is followed by granulation, grinding or spraying.
  • a cold mix consists of suitable polymer supports such as polyethylene, polypropylene or ethylene vinyl acetate copolymer and the like.
  • suitable polymer supports such as polyethylene, polypropylene or ethylene vinyl acetate copolymer and the like.
  • the disadvantage of these polymer blends is that the proportion of polymer allows only a limited addition of short-chain components. If the saturation range is exceeded, and this can often already be around or below 10%, separation of the polymer and the lubricating, separating and lubricating additives occurs.
  • DE-A 15 44 830 discloses a pigment preparation in which the pigment particles are enveloped by an amorphous homopolymer or copolymer of propylene, butene-1 and hexene-1 or a propylene-ethylene block polymer. In the preparation of the pigment preparation, filtration and drying steps are required.
  • DE-A 12 39 093 describes support materials based on a mixture of an amorphous ethylene-propylene block copolymer and a crystalline polypropylene for the production of pigment concentrates.
  • DE-A 26 52 628 refers to the use of polypropylene waxes having a viscosity of 500 to 5,000 mPa.s (170 0 C) and an isotactic content of 40 to 90%.
  • DE-A 195 16 387 a highly effective dispersion is achieved by a dispersant which contains a mixture of different polyolefin and special polyacrylic acid esters.
  • JP-A 88/88287 preparations consist of pigment, lubricants, fillers and an amorphous polyolefin.
  • DE-A 26 08 600 relates to pigment concentrates for coloring thermoplastics containing pigment, polyolefin wax, an ethylene-vinyl acetate copolymer and colloidal silica.
  • All lubricant, lubricant and release agent preparations hitherto used in practice must, if they have an active ingredient content of more than 10%, be prepared with a relatively complex process equipment, such as e.g. underwater pelletizing. Due to the high loading, the strand strength of the produced masterbatches will be lower. Strand pelletizing is state of the art at masterbatch companies.
  • One possibility of improvement would theoretically be the use of special polymers that flow readily, that are processable at lower temperatures, and that are well tolerated by different polymers. However, polymers that have this property pattern have higher purchase costs.
  • the object of the present invention was to load active ingredient compositions with the highest possible proportion of liquid, low-melting or low-viscosity components such as lubricants, release agents and lubricants, in order to produce foamed or unfoamed plastomers and elastomers with good release properties and good sliding properties , economically and ecologically advantageous can be accomplished and so high-quality products.

  • a polymeric carrier should be largely dispensed with, which on the one hand active ingredient compositions with a significantly higher content of lubricants, release agents and lubricants are possible and on the other hand, the finished preparations can be used in significantly more different polymers with different chemical composition than before, because there are fewer compatibility problems due to the high loading.
