Definitions

  • the object of the present invention is to develop environmentally friendly, in particular occupationally less harmful corrosion protection pigments which are able to replace zinc and strontium chromate, especially in base coats for different metal substrates.
  • Chromic acid can be improved significantly.
  • the invention accordingly relates to metal oxide
  • -phosphate and / or molybdate-containing corrosion protection pigments preferably basic metal phosphate and molybdate pigments based on the metals zinc, aluminum, iron, barium, strontium, calcium, magnesium and titanium, individually or in combination, in addition to metal oxide,
  • Metal phosphate and / or metal molybdate has a soluble sodium dichromate content of 0.03-2% by weight, preferably 0.2-0.6% by weight, or equivalent amounts of potassium or ammonium dichromates or equivalent amounts of the corresponding Chromates or chromic acid, based on the total weight of the pigment.
  • the combination for example the basic metal phosphate pigments with the soluble alkali metal or ammonium dichromate or the corresponding chromate or chromic acid, has proven to be particularly effective according to the invention if it combines with the pigment sludge of the base pigment after the chemical reaction and wet confectioning are thoroughly mixed before drying, in particular using shear forces. In this way, the uniform distribution of the dissolved chromate component required for optimum effectiveness can be achieved.
  • the uniform and optimal distribution of the chromate component in the pigment or in a pigment combination . n is also possible by dry mixing the components, but subsequent intensive grinding, for example in a pin, turbo or jet mill, is necessary.
  • This preparation of the dried pigment can also be advantageous if the chromate components are added to the wet pigment before drying. In both cases, final screening to achieve fractions with certain particle sizes can be advantageous for certain applications.
  • a further advantageous variant of the combination of the corrosion protection pigment with the chromate components mentioned is to add pigments and / or fillers such as titanium dioxide, barium sulfate or talcum etc. to the pigment sludge before drying or the dried pigment after addition of the chromate components mentioned usually used in the formulation of primers.
  • the pigments and filler components can also be added before the soluble chromate components are added.
  • the amount of such additives is preferably 5 to 20% by weight, in particular 15 to 20% by weight, of the total pigment. -4- l According to a preferred embodiment, the
  • Example 1 basic zinc phosphate is prepared and this is then in the aqueous slurry at a temperature of 70 - 90 ° C with an almost boiling solution of 0.8 wt .-% (based on dry pigment) phthalic anhydride and 10 parts of water for a period of 30 min.
  • the product separated by filtration is mixed with 0.3% by weight (based on dry pigment) of sodium dichromate, this is mixed in uniformly in an intensive mixer and then the pigment sludge is dried at 105 ° C. and the dried product is then ground or marry and sighted.
  • Example 2 basic zinc phosphate is prepared, then phthalic acid or phthalic anhydride is added in the manner described, 10% by weight (based on dry pigment) barium sulfate and 10% by weight (based on dry pigment) talc are then added and after the addition from 0.4. % By weight (based on dry pigment) sodium dichromate is mixed intensively. The pigment sludge obtained is then dried at 105 ° C. and the dried product is then ground or ground and classified.
  • the basic zinc phosphate prepared according to Example 3 with barium and talc is dried (without the addition of dichromate) at 105 ° C. and, after dry preparation, 0.4 wt.% Ammonium dichromate is added in a mixer and the intensively premixed product is then added grind on a turbo mill.
