Abstract

Use of lipophilic micronized waxes (I) in oil colors and lacquers. An independent claim is also included for the preparation of oil colors and lacquers comprising simple stirring (I) in the oil colors and lacquers without a separate and/or expensive dispersion process.

Description

object The invention relates to the production and use of lipophilic micronized waxes that are simply stirred into oily paints and varnishes can, without a separate or complex dispersion process. The economy The production of paints and varnishes (oil-based) is greatly improved.

The term waxes (defined by the German Society for Fat Science [DGF, 1957 and 1974]) understands this invention

• A natural waxes

Micronized waxes are waxes with an average fineness (D 50 value) of 5-10μm. The inventor defines these waxes as 99% <100 μm. The definition and measurement of the grain size is carried out by means of laser diffraction according to ISO 13320-1 (eg Malvern, Sympatec).
This invention describes:

• A lipophilic micronized carnauba wax
• B Lipophilic micronized amide waxes
• C Lipophilic micronized montan waxes
• D Lipophilic micronized polyolefin waxes
• E Lipophilic micronized microcrystalline waxes
• F Lipophilic micronized paraffin waxes
• G Lipophilic micronized Fischer-Tropsch waxes

lipophilic Micronized waxes are waxes that are spray-micronized according to the "DEUREX INSTANT PROCEDURE" become. The spray takes place from the wax melt directly into the submitted oil, at the same time as a coolant serves. The oil with it sheathed Waxes (without oxygen) can do not agglomerate and are in oily Colors and paints directly, simply stir. A complex dispersion with high expenditure of time, energy costs and personnel costs is not more necessary. The production capacity and cost effectiveness of Color and paint production can thus be significantly increased.

Colours and paints are liquid and solid colorants for the Paint and varnish industry. This invention speaks of each of these applications in oily medium (e.g., sheetfed offset, heatset)

Dispergierunq is the decomposition and distribution of solid components in a dispersion medium (here oils). To the Achievement of this process objective are emulsifiers as auxiliary materials and stabilizers in a small proportion of the mixture to be dispersed added to support the distribution and longevity to ensure the dispersion to be generated. By this invention can on auxiliary materials when using the lipophilic micronized Growing be waived.

• A ... die Verwendung und Herstellung von lipophilen mikronisierten Wachsen, die einfach in ölige Farben und Lacke eingerührt werden können, ohne einen separaten bzw. aufwendigen Dispergierprozess (Die Einfachheit dieses Einrührvorganges kann man mit dem Einführen eines Instant-Kaffees verglei chen). Die Wirtschaftlichkeit der Herstellung von Farben und Lacke (auf Ölbasis) wird enorm verbessert.
• B ... die Herstellung von lipophilen mikronisierten Wachsen, die nach dem „DEUREX INSTANT VERFAHREN" sprühmikronisiert werden. Die Sprühung erfolgt aus der Wachsschmelze direkt in das vorgelegte Öl, das gleichzeitig als Kühlmittel dient. Die damit mit Öl umhüllten Wachse (ohne Sauerstoff) können nicht agglomerieren und sind in öligen Farben und Lacken direkt und einfach einrührbar. Eine aufwendige Dispergierung mit hohem Zeitaufwand, Energiekosten und Personalkosten ist nicht mehr notwendig. Die Produktionskapazität und Wirtschaftlichkeit der Farben- und Lackherstellung kann damit deutlich erhöht werden.
• C ... die Verwendung von lipophilen mikronisierten Wachsen erspart dem Farben- und Lackhersteller jegliche Nachmahlung, da das jeweilige lipophile mikronisierte Wachs bereits die notwendige Feinheit hat. Diese Feinheit wird dem Kunden garantiert.

The subject of this invention is ...

• A ... the use and production of lipophilic micronized waxes that can be easily stirred into oily paints and varnishes, without a separate or complex Dispergierprozess (The simplicity of this stirring process can compare with the introduction of an instant coffee chen). The cost-effectiveness of the production of paints and varnishes (oil-based) is enormously improved.
• B ... the production of lipophilic micronized waxes, which are spray-micronised according to the "DEUREX INSTANT PROCEDURE." The spraying takes place from the wax melt directly into the supplied oil, which simultaneously serves as a coolant, and the wax-coated waxes (without oxygen) can not agglomerate and can be stirred in oily paints and varnishes directly and simply.A costly dispersion with high expenditure of time, energy costs and personnel costs is no longer necessary.Thus, the production capacity and efficiency of the paint and varnish production can be increased significantly.
• C ... the use of lipophilic micronized waxes spares the paint and varnish manufacturer any regrind, since the respective lipophilic micronized wax already has the necessary fineness. This fineness is guaranteed to the customer.

• A Separate Vordispergierung von Wachspasten ist nicht mehr nötig.
• B Separate Nachmahlung (trocken oder nass) von Wachsen bzw. Wachspasten ist nicht mehr nötig.
• C Die Herstellkosten zur Fertigung dieser Dispersionen entfallen komplett.
• D Das lipophile mikronisierte Wachs kann direkt der Farbe, dem Lack, dem Firniss zudosiert werden.
• E Vermeidung von Stäuben, Vermeidung von Ex-Gefahren

The use of lipophilic micronized waxes in oily paints and lacquers achieves the following advantages [and / or]:

• A Separate predispersion of wax pastes is no longer necessary.
• B Separate regrinding (dry or wet) of waxes or wax pastes is no longer necessary.
• C The manufacturing costs for the production of these dispersions are completely eliminated.
• D The lipophilic micronized wax can be added directly to the paint, varnish or varnish.
• E Avoidance of dusts, avoidance of dangers

EXAMPLES

Micronized waxes or sprayed micronised waxes traditionally produced by air mills are coated with atmospheric oxygen, have relatively high dust levels and tend to agglomerate. This property is independent of the type / nature of the waxes described under point [0002]. The finer these micronized waxes, the greater The surface is the larger and this agglomeration is greater.
When adding doses of these waxes to oils, the micronized wax described in [0009] always floats on the surface of the oil. After simply stirring in, this wax always stays on the surface, it floats on the surface. The system is unstable and consists of two phases.
As an exemplary embodiment can here any commercially available micronized wax (eg DEUREX ^® ME 0825, micronized polyethylene wax) are stirred manually in commercially available linseed oil in each dose.

was standing The technique is the dispersion of these waxes [0009] by means of high energies, good mixing technique and partly by means of afterthought Grinding (e.g., ball mills). To achieve this process goal are often called auxiliary materials Emulsifiers and stabilizers in a small proportion of the to be dispersed Mixture added to aid the distribution and to ensure the longevity of the dispersion to be produced

The lipophilic micronized waxes described in this invention are spray-micronised according to the "DEUREX INSTANT PROCEDURE." The spray is made from the wax melt directly into the charged oil, which also serves as the coolant, and the wax-coated waxes (without oxygen) can not agglomerate are easy to stir in oily paints and varnishes, eliminating the need for time-consuming dispersion, energy and labor costs, and significantly increase the production capacity and cost-effectiveness of paint and varnish production.
As a performance example, each DEUREX INSTANT WAX can be stirred in at any desired concentration with commercial lacquer oil. Already this simple stirring is stable for several hours. With commercially available technical stirring technologies, the stability of these lipophilic micronized waxes is exactly the same as described under [0010] (but without complicated dispersion and without auxiliary materials).
