Definitions

  • the invention relates to the use of compositions based on partial esters of glycerol and / or polyglycerols and perchlorates as internal antistatic agents for thermoplastics.
  • Plastics such as polyethylene, polypropylene and PVC are pronounced non-conductors, i.e. high-quality electrical insulators. This property causes the surface to be electrically charged and, due to the dust attraction associated with it, moldings quickly become dirty and unsightly. These disadvantageous properties can largely be prevented by antistatic agents.
  • the object of the present invention was to provide compositions which are suitable for the antistatic finishing of thermoplastic organic plastics, in particular polyethylenes, polypropylenes, polycarbonates and polyvinyl chloride, without adversely affecting the application properties of the plastics.
  • thermoplastic organic plastics in particular polyethylenes, polypropylenes, polycarbonates and polyvinyl chloride
  • the compositions to be provided should not cause any losses in terms of thermal and / or photochemically induced degradation of the plastic.
  • compositions as internal antistatic agents for thermoplastics, the compositions comprising:
  • polyhydric alcohols which are selected from the group glycerin and polyglycerols and
  • the compounds A) are partial esters of fatty acids with 6 to 22 carbon atoms with polyhydric alcohols, which are selected from the group of glycerol and polyglycerols.
  • the fatty acids on which the compounds A) are based can be saturated or unsaturated, straight-chain or branched.
  • suitable fatty acids are hexanoic acid, heptanoic acid, octanoic acid, 2-ethyl-hexanoic acid, decanoic acid, lauric acid, tridecanoic acid, myristic acid, pentadecanoic acid, palmitic acid, heptadecanoic acid, stearic acid, 12-hydroxystearic acid, nonadecanoic acid, arachic acid,

  • the perchlorate salts can be complexed with alcohols, for example polyols, cyclodextrins, or ether alcohols or ester alcohols, or dissolved therein.
  • the polyol partial esters are also to be counted among the ester alcohols.
  • polyhydric alcohols or polyols their dimers, trimers, oligomers and polymers, such as di-, tri-, tetra- and polyglycols, and also di-, tri- and tetrapentaerythritol or polyvinyl alcohol in various degrees of polymerization are also suitable.

  • the perchlorate salts can be used in various common dosage forms, for example as a salt or solution in water or an organic solvent as such, or applied to a support material such as PVC, calcium silicate, zeolites or hydrotalcites, or incorporated into a hydrotalcite by chemical reaction or another layered grid connection.
  • a support material such as PVC, calcium silicate, zeolites or hydrotalcites, or incorporated into a hydrotalcite by chemical reaction or another layered grid connection.
  • Glycerol monoethers and glycerol monothioethers are preferred as polyol partial ethers.
  • the perchlorates can be used both individually and in a mixture with one another.
  • compositions to be used according to the invention can expediently be incorporated into antistatic thermoplastic materials by the following methods:
  • thermoplastic material equipped with the compositions mentioned contains the compounds (B) in an amount of 0.001 to 1.0 phr and in particular 0.002 to 0.5 phr, the weight ratio of the compounds (A) to the compounds (B) 1000: 1 to 1000: 200.
  • the term phr ("parts per hundred resin") familiar to the person skilled in the art indicates how many parts by weight of the component are present in PVC, based on 100 parts by weight of PVC.
  • the antistatic thermoplastic material according to the present invention can be brought into the desired shape in known ways. Such processes are, for example, calendering, extruding, injection molding, sintering or spinning, furthermore extrusion blowing or processing according to the plastisol process. Plastisol processing, extrusion and calendering are particularly preferred.
  • PVC (I): S-PVC (K-value 60)
