Definitions

  • the present invention relates to the use of hydrocalumite-type compounds as stabilizers for halogen-containing thermoplastic resins.
  • Halogen-containing, thermoplastic resins and molded parts made from them are broken down or decomposed by exposure to heat and light. This degradation or decomposition process manifests itself through discoloration of the resin mass, whereby a change in properties (e.g. mechanical strength) can also be observed.
  • stabilizers are preferably used in combination with other organic substances.
  • a conventional stabilizer is based, for example, on the use of zinc or cadmium salts in combination with metal salts from group Ha of the periodic table.
  • organic and / or inorganic compounds of lead are also used to stabilize halogen-containing polymers.
  • the invention has for its object to achieve the stabilization of halogen-containing thermoplastic resins by means of compounds which do not have the disadvantages of the known stabilizers mentioned above, in particular are classified as non-toxic.
  • PVC halogen-containing, thermoplastic resins
  • the compounds used according to the invention achieve both the desired long-term stability and adequate color retention during thermal exposure.
  • hydrocalumite-type compounds used according to the invention are known compounds.
  • EP-A-0 278 535 describes the use of a hydrocalumite as part of a catalyst composition suitable for converting hydrocarbons.
  • the preparation of compounds of the hydrocalumite type is also mentioned here.
  • Compounds of the hydrocalumite type which are suitable for the use according to the invention can also be prepared, for example, by means of a process in which mixtures of water-soluble calcium and aluminum salts are mixed with sodium hydroxide solution in an amount corresponding to the preparation of the desired compounds in an aqueous medium until a pH of about 10 is reached.
  • This forms a suspension from which the reaction product is separated and recovered in a manner known per se, for example by filtering, washing and drying.
  • the suspension is mixed with a known stabilizer coating agent, for example stearic acid, before it is separated off. This improves the dispersibility of the compounds used as stabilizers in the halogen-containing thermoplastic resins.
  • the compounds used according to the invention can be combined with other known stabilizers for halogen-containing thermoplastic resin compositions. examples for this are
  • Polyols such as polyhydric alcohols, especially trimethylolpropane, glycerol, pentaerythritol, polyvinyl alcohol and their di- or oligomers or also partial esters thereof;

  • Isocyanurates e.g. Trish. .roxyethyl isocyanurate
  • Dihydropyridines e.g.
  • Thioglycolic acid esters e.g. 2-ethylhexylthioglycolate.

  • Substances usually used, such as, for example, di (2-ethylhexyl) phthalate, can be used as plasticizers.
  • additives and stabilizers can be added to the polymer individually or as mixtures of several components.
  • the additive and stabilizer mixture can be used in powder form, as granules or as a melt product.
  • Thermoplastic halogen-containing resins are, in particular, polyvinyl chloride (PVC), polyvinylidene chloride, chlorinated polyethylene, chlorinated polypropylene and copolymers for the production of which vinyl chloride has been used, as well as mixtures of halogen-containing polymers with other poly esisites.
