Definitions

  • Flowable dispersion comprising particulate metal oxides, metal oxide hydrates and / or metal hydroxides, a dispersant and an organic dispersion medium.
  • the invention relates to a flowable dispersion containing at least one particulate metal oxide, metal oxide hydrate and / or metal hydroxide as a suspended solid, a dispersant and an organic liquid dispersion medium and the use of the dispersant.
  • Powders are incorporated as solids in paints, films, coatings and molding compounds to positively affect properties such as tensile and compressive strength, abrasion resistance and processability.
  • functional fillers can impart additional properties to the materials, such as colourfastness, UV protection, magnetic, optical or electrical properties.
  • the powders are often incorporated in the form of suspensions, i. as solids which are dispersed in a liquid medium but in which they themselves are not or only very slightly soluble and do not chemically bond to one another.
  • a liquid dispersion medium and a dispersed solid are present, this is referred to as a suspension.
  • dispersions i. heterogeneous mixtures of at least two substances, wherein in the present case at least the dispersion medium is liquid (continuous phase) and at least the dispersed substance or the dispersed mixture is solid (disperse phase).
  • other substances may also be present, e.g. are also gaseous, or the liquid continuous phase contains, in addition to the dispersant and the dispersion medium as a further disperse phase, a liquid.
  • the solids are homogeneously dispersed in the liquid dispersion medium. This is the more difficult the finer the solids used and the worse the compatibility or compatibility between solid and liquid dispersion medium.
  • the viscosity and the stability of the resulting mixture In general, the addition of finely divided solids results in an increase in viscosity.
  • the viscosity may increase unacceptably even after dispersion.
  • the present invention has thus set itself the task of providing liquid dispersions of suitable viscosity and, if desired, a high solids content available.
  • a disadvantage of the use of surface modifiers is the required exact knowledge of the surface to be modified. Surface modifiers that are used in excess and do not interact with the surface can lead to difficulties in working up the material. A deficiency of surface modifiers generally does not lead to dispersing or only to an insufficient degree.
  • Dispersing additives are added.
  • Dispersions of aluminum oxides, including boehmites, in organic solvents using surfactants as dispersants are e.g. known from WO 2009/051905 A2.
  • J. Am. Ceram. Soc, 89 [3] 882-887 (2006) describes the surface modification of gamma-aluminum powder with oleic acid and subsequent dispersion in non-polar solvents.
  • Colloids and Surfaces, 56 (1991) 25-43 discloses dispersions of clays in toluene and THF.
  • the dispersants used were linolenic acid or polyisobutylene succinimides, such as the commercial product OLOA 1200. Linolenic acid provided a 58 vol.% Dispersion, OLOA 1200 a 66 vol.% Dispersion.
  • the object could be achieved in a surprising manner by the dispersion according to the invention or the dispersant used, as described in the independent claims. Preferred embodiments are subject of the dependent claims or described below.
  • the dispersant is characterized by the fact that metal oxides, metal oxide hydrates, metal hydroxides and their mixtures can be dispersed in organic solvents or diluents with mechanical energy input to liquid dispersions, even those with a high solids content.
  • metal oxide is to be understood to include half metal oxides but excludes nonmetal oxides.
  • Semi-metal oxides are attributed to the metal oxides. In principle, all forms and modifications are meant in the case of several possible oxidic forms of an element from the group of the elements included. The same applies to metal oxide hydrates and metal hydroxides. Also included are the permutations of the groups, ie metals which carry oxide, hydrate and / or hydroxide groups.
  • the metals on which the metal oxides or metal oxide hydrates and metal hydroxides are based are preferably transition metals, rare earths and / or aluminum. Also included in several metals are mixed oxides and crystal modifications containing several of the metals, in particular consisting of several of the metals. The same applies to metal oxide hyd hydrates and metal hydroxides.
  • the average particle diameter of the dispersed metal oxide, metal oxide hydrat- or metal hydroxide particles - as determined by light scattering in the dispersion - is on average less than 200 nm, preferably less than or equal to 100 nm. Particularly preferred is the particle diameter of 10 to 100 nm and in particular 40 to 80 nm.
  • a boehmite and / or alumina dispersion preferably has a color number which is less than 10 Hazen and more preferably less than 5 Hazen (in each case measured according to DIN EN 1557).
  • the proportion of metal oxides, metal hydroxides and / or metal oxide hydrate in the dispersion is preferably from 1 to 80% by weight, preferably from 5 to 70% by weight, particularly preferably from 20 to 60% by weight.
  • the dispersant has the following general formula
  • R is an aliphatic hydrocarbon radical (linear or branched or cyclic) having 6 to 36 carbon atoms, in particular 12 to 24 and particularly preferably 13 to 17,
  • X is hydrogen or a counter cation
  • d is in each case 3 to 30 on average, in particular 5 to 30 on average, particularly preferably 4 to 12.
  • the dispersant preferably has a proportion of 1 to 10 wt.% Of the total weight of the dispersion.
  • the dispersant may contain potassium chloride, sodium chloride, chloroacetic acid, a residual water content, a residual content of an alcohol R-OH, and a residual content
  • R, AO and d have the meaning of above.
  • the dispersion according to the invention contains as further essential constituent an organic solvent selected from the group of protic and aprotic solvents.
  • the organic solvent of the dispersion according to the invention is in particular to be selected from the group of linear and branched aliphatic alcohols, aromatic alcohols, esters, ketones, cyclic ethers, aliphatic ethers and aromatic solvents.
