Definitions

  • the invention relates to compositions for coating, sealing and gluing with electrically non-conductive polymers and electrically conductive fillers, their production and use for the production of electrically conductive coatings, seals and adhesives.
  • non-conductive organic polymers conductive by adding conductive fillers such as carbon black, graphite, metal powders and metal compounds and carbon fibers. If these fillers form a continuous network, the specific conductivity of the polymer is namely improved by several powers of ten, so that, for example, electrical charges are avoided, shielding against electromagnetic waves is made possible, and dangerous or even annoying electrostatically induced discharge processes are prevented.
  • conductive fillers such as carbon black, graphite, metal powders and metal compounds and carbon fibers.
  • compositions are then black, they are pasty and difficult to apply.
  • their viscosity can be reduced by adding solvents or water, but such dilutions also have disadvantages: They limit the storage stability (solvation of the soot micelles). Most of the time, the strength also decreases. Finally, dilution with organic solvents leads to flammability of the composition and further disadvantages such as instability of the set conductivity (rapid decrease in the set conductivity over time).
  • Bright, conductive, aqueous dispersion adhesives are known, e.g. THOMSIT K 112 and THOMSIT T 412 from Henkel Bautechnik GmbH, which contain 0.8 to 1.5% by weight of carbon fibers with a length of 3 mm. If you apply this to not too smooth underlays with pointed-toothed spatulas, you get bonds with an electrical resistance of less than 3 x 10o5 ohms, measured according to DIN 53276. This conductivity is required for dispersion PVC flooring materials from DIN 16860.
  • Bright (white and colored) conductive pigments are also known, which can also be used in an aqueous medium.
  • the company Sachtleben Chemie GmbH describes in its brochure "Electrically conductive pigments" (11 / 1989-1000 / 8-014) inorganic pigments based on titanium oxide, zinc oxide and zinc sulfide with powder conductivities from 1 ⁇ 10 -2 to 6 ⁇ 10 - 2 S / cm.

  • electrically conductive floor coatings made of synthetic resins which are electrically conductive fillers from 60 to 100 parts by weight / 100 Parts by weight of binder containing zinc oxide with 0.1 to 0.4 wt .-% aluminum.
  • Conventional polymers are used on synthetic resins, which cross-link on contact with air, e.g. epoxy,
  • Fibers are added to improve the mechanical properties, for example carbon, steel, glass or synthetic organic fibers.
  • the formulation, which is only effective in the absence of water, is not suitable, for example, for large-scale use for conductive floor coverings, where dispersion-based adhesives have prevailed for economic, occupational hygiene and ecological reasons.
  • the object of the invention is to find an economically justifiable bright composition for coating, sealing and gluing, which has an electrical resistance of preferably ⁇ 3 ⁇ 10 5 Ohm, but at most 1 ⁇ 10 7 Ohm and its processability and achievable adhesive strength compared to non-conductive Adhesives is practically unchanged.
  • the solution according to the invention can be found in the patent claims. It is based essentially on the synergistic effect of conductive pigments and carbon fibers. Even very small amounts of carbon fibers and small amounts of conductive pigments lead to a sudden reduction in electrical resistance by a factor of up to 10 ⁇ . This effect is surprising since neither the conductive pigments nor the carbon fibers have such an effect in the stated concentrations, not even as the sum of the individual effects.
  • the resistance of an acrylate adhesive becomes 5% by weight of a conductive titanium oxide and 0.25% by weight of one Carbon fiber reduced to 5 x 10 6 ohms.
  • the resistance of the adhesive with 5% titanium oxide alone is approximately 1 x 10 11 ohms. If 0.25% by weight of carbon fibers is added to the adhesive, the resistance is more than 10 10 .
  • the light-colored metal compounds mentioned are white, yellow, orange or other light-colored pigments, which allow a light setting of products made from them and are fundamentally different from previously known dark (carbon black, graphite, finest metal powder) or metallic (aluminum “powder", bronze “powder) "and the like) distinguish conductive feedstocks.
  • these new conductive pigments are pigments based on titanium dioxide, zinc oxide,

  • the electrically conductive rutile mixed-phase pigment is produced essentially by adding a mineral-acidic aqueous dispersion of a rutile-mixed-phase pigment to a solution containing mineral-acid hydrolyzable tin compounds and a solution containing mineral-acid hydrolyzable antimony compounds, with constant stirring, the hydrolyzable compounds by increasing the pH -Values are hydrolyzed and that coated with the hydroxide precipitates Rutile mixed-phase pigment, if appropriate after aging, is separated off, dried and calcined.
  • rutile mixed-phase pigment containing (Ti, Ni, Sb) oxide (Sicotan Yellow L 1010 from BASF AG) (specific surface area 3 m 2 / g) are suspended in 400 ml of water at 70 ° C. and adjusted to pH 2 with hydrochloric acid. Then 500 ml of water are suspended at 70 ° C and adjusted to pH 2 with hydrochloric acid. Then 500 ml of water at 70 ° C, 1 ml of SnCl 4 and 1 ml of HCl (conc.) Are added.

  • the electrically conductive zinc sulfide particles are essentially prepared by combining an aqueous solution or suspension of a copper salt with a pH of 2 to 12 and zinc sulfide particles with vigorous stirring and separating the zinc sulfide particles provided with a copper sulfide coating by surface reaction and worked up. For example, 29.2 g of CUSO 4 x 5 H 2 O are dissolved in 800 ml of H 2 O and the pH is adjusted to 9 with concentrated ammonia solution. Then 100 g of ZnS in powder form (d 50 1 ) 0.37 ⁇ m; specific surface area 6.8 m 2 / g BET method) with stirring within one minute. The resulting copper sulfide represents 11% of the product.

  • a ZnS suspension is used, there are a few dissolved S ions following the ZnS solubility product. After their precipitation as CuS, the conditions correspond to those when using ZnS powder (Example 1 of DE 3929056).
