Description

Bei der Abfüllung von Lebensmitteln müssen die Gefäße mit Hilfe von speziellen Transportbändern, insbesondere Flaschentransportbändern, bewegt werden. Solche Transportbänder bestehen in der Regel aus Edelstahl, in seltenen Fällen aus Kunststoff. Um die Bewegung der Gefäße, d.h. Flaschen oder sonstige Gefäße aus Glas oder Kunststoff, zu erleichtern müssen die Bänder mit einem Gleitmittel (sog. Bandschmier- oder Kettengleitmittel) geschmiert werden.When filling food, the containers must be transported using special conveyor belts, in particular bottle conveyor belts. Such conveyor belts exist usually made of stainless steel, in rare cases made of plastic. To the movement of the vessels, i.e. Bottles or other vessels made of glass or plastic must be lightened with the tapes be lubricated with a lubricant (so-called belt lubricant or chain lubricant).

Es sind Bandschmiermittel von unterschiedlicher Zusammensetzung bekannt. So sind Bandschmiermittel beispielsweise auf Basis von Seifen (Salze von Fettsäuren), auf Basis carboxylierter Niotenside (Ethercarbonsäuren), auf Basis von Aminen (mit primären, sekundären, tertiären Aminen und Kombinationen davon, wobei die Amine auch als Salze vorliegen können) bekannt. Weiterhin sind ebenfalls Bandschmiermittel auf Basis von Diaminen, insbesondere Dipropionamine und auf Basis von phosphatierten Alkanolethoxylaten bekannt.Belt lubricants of different compositions are known. So are band lubricants for example based on soaps (salts of fatty acids) based on carboxylated Nonionic surfactants (ether carboxylic acids), based on amines (with primary, secondary, tertiary Amines and combinations thereof, where the amines can also be present as salts). Furthermore, band lubricants based on diamines, in particular dipropionamines, are also used and based on phosphated alkanol ethoxylates.

In der EP 0 652 927 B1 werden Schmiermittelkonzentrate und wässerige Schmiermittellösungen auch Basis von Fettaminen beschrieben. Die dort erwähnten Fettamine sind Etheramine und enthalten mindestens drei Stickstoffatome und gehören somit zur Gruppe der Triamine.EP 0 652 927 B1 describes lubricant concentrates and aqueous lubricant solutions also described the basis of fatty amines. The fatty amines mentioned there are ether amines and contain at least three nitrogen atoms and thus belong to the group of triamines.

EP 372 628 B1 beschreibt den Einsatz von Bandschmiermittelkonzentraten, welche bis zu 30 Gew.% Fettamine enthalten.EP 372 628 B1 describes the use of belt lubricant concentrates which contain up to 30 % By weight contain fatty amines.

Mit den obenerwähnten Aktivsubstanzen, allein oder in Kombination miteinander, und gegebenenfalls mit Zusatz von Hilfsmitteln und Additiven wie z.B. Lösungsmitteln, Komplexierungsmitteln, thresholdaktiven Substanzen, Hydrotrope, Harnstoff, Biozide, speziellen organischen Säuren und anderen mehr kann man vielfältige Bandschmiermittel formulieren.With the above-mentioned active substances, alone or in combination with one another, and if appropriate with the addition of auxiliaries and additives such as Solvents, complexing agents, threshold active substances, hydrotropes, urea, biocides, special organic Acids and others can be formulated in a variety of belt lubricants.

Bei der Anwendung der bekannten Bandschmiermittel können verschiedene Probleme entstehen, welche bis heute nicht oder nur teilweise gelöst worden sind:

  • Es kann durch eine zu hohe Empfindlichkeit gegenüber verschiedenen Ionen im Betriebswasser wie beispielsweise Carbonat-, Hydrogencarbonat-, Sulfat oder Erdalkaliionen eine Ausfällung verursacht werden, welche zur Verstopfung der Sprühdüsen und zur Abnahme der Leistung führt.
  • Durch eine ungenügende reinigende Wirkung sammelt sich auf das Transportband, und insbesondere zwischen den einzelnen Kettengliedern aus denen es besteht störender Schmutz an.
  • Durch eine ungenügende biozide Wirkung kann das Transportband von Mikroorganismen befallen werden, während eine zu starke biozide Wirkung zu Problemen in der Funktion von Kläranlagen führen kann.
  • Bei einer zu starken Schaumentwicklung wird die Flaschenkontrolle an den Lichtschranken gestört.
  • Eine starke Empfindlichkeit gegenüber Resten von der abzufüllenden Flüssigkeit wie z.B. Bier, Milch, Fruchtsäfte, Mineralwasser auf dem Transportband bewirkt eine rasche Abnahme der Schmierwirkung der obengenannten Bandschmiermittel.
  • Zudem tritt die der Schmierwirkung am Anfang der Produktion häufig verzögert ein.
Various problems can arise when using the known belt lubricants, which have not been solved or only partially solved to date:
  • If the sensitivity to various ions in the process water, such as carbonate, hydrogen carbonate, sulfate or alkaline earth ions, is too high, precipitation can occur, which leads to blockage of the spray nozzles and to a decrease in performance.
  • Due to an inadequate cleaning effect, it accumulates on the conveyor belt, and in particular between the individual chain links from which it consists of disruptive dirt.
  • An insufficient biocidal effect can infect the conveyor belt with microorganisms, while an excessive biocidal effect can lead to problems in the functioning of sewage treatment plants.
  • If the foam development is too strong, the bottle control on the light barriers is disturbed.
  • A strong sensitivity to residues from the liquid to be filled such as beer, milk, fruit juices, mineral water on the conveyor belt causes a rapid decrease in the lubricating effect of the above-mentioned belt lubricants.
  • In addition, the lubricating effect is often delayed at the start of production.

Die heute bekannten Bandschmiermittel werden von den Herstellern als wässerige, verdünnte Lösungen den Endverbrauchern angeboten. Sie enthalten meist 2-15 Gew.% Hauptwirkstoff, meist Alkylamine und deren Derivate, außerdem unterschiedliche Mengen an weiteren Hilfs- bzw. Zusatzstoffen (Tenside, Lösungsmittel, Komplexierungsmittel, Säuren, usw.). Diese wässerigen Lösungen werden dann bei der Anwendung, direkt auf der Anlage weiter verdünnt. Auf dem Förderband beträgt die Konzentration an Hauptwirkstoff ca. 50 -300 ppm.The band lubricants known today are diluted by the manufacturers as watery Solutions offered to end users. They usually contain 2-15% by weight of the main active ingredient, mostly alkylamines and their derivatives, also different amounts of other auxiliary or additives (surfactants, solvents, complexing agents, acids, etc.). This watery Solutions are then further diluted directly on the system during use. On The concentration of the main active substance on the conveyor belt is approx. 50-300 ppm.

Es wäre jedoch wirtschaftlich von sehr großem Vorteil, wenn man wasserfreie bzw. beinahe wasserfreie Bandschmiermittelkonzentrate anwenden könnte, die wesentlich höhere Mengen an Wirkstoffen enthalten. Dadurch würde man wesentliche Kosteneinsparungen realisieren (Produktions-, Verpackungs- und Frachtkosten).However, it would be economically very advantageous to have water-free or almost water-free Tape lubricant concentrates could apply much higher amounts Contain active ingredients. This would result in significant cost savings (production, Packaging and freight costs).

Bandschmiermittelkonzentrate mit hohem Anteil an Fettalkylaminen werden bereits in EP 372 628 B1 erwähnt. Darin werden Etheramine der allgemeinen Formel: R2R1-N-A-NH2 erwähnt, wobei
R1 eine gesättigte oder ungesättigte , verzweigte oder lineare Alkylgruppe mit 8 bis 22 C-Atomen ist;
R2 Wasserstoff, eine Alkyl- oder Hydroxyalkylgruppe mit 1 bis 4 C-Atomen oder -A-NH2;
A eine lineare oder verzweigte Alkylengruppe mit 1 bis 8 C-Atomen bedeutet.Belt lubricant concentrates with a high proportion of fatty alkyl amines have already been mentioned in EP 372 628 B1. It contains ether amines of the general formula: R 2 R 1 -NA-NH 2 mentioned where
R 1 is a saturated or unsaturated, branched or linear alkyl group with 8 to 22 C atoms;
R 2 is hydrogen, an alkyl or hydroxyalkyl group having 1 to 4 carbon atoms or -A-NH 2 ;
A represents a linear or branched alkylene group with 1 to 8 carbon atoms.

Gemäß EP 372 628 B1 ist es allerdings essentiell, dass die Fettamine der oben genannten Formel nur bis zu 30 Gew.% in den Bandschmiermittelkonzentraten enthalten sind. Bislang war es nämlich technisch nicht möglich, Bandschmiermittelkonzentrate herzustellen, die über 30 Gew.% Fettamine der oben angegebenen allgemeinen Formel enthalten.According to EP 372 628 B1, however, it is essential that the fatty amines of the above formula only up to 30% by weight are contained in the belt lubricant concentrates. So far it was technically not possible to produce belt lubricant concentrates that exceed 30% by weight Contain fatty amines of the general formula given above.

Daher ist es Aufgabe der vorliegenden Erfindung, Bandschmiermittel- oder Kettengleitmittelkonzentrate mit einem neuen Wirkstoff bereit zu stellen, wodurch wasserfreie Bandschmiermittelkonzentrate mit wesentlich höheren Mengen an Wirkstoffen erhalten werden können.It is therefore an object of the present invention to concentrate belt lubricants or chain lubricants to provide with a new active ingredient, making anhydrous tape lubricant concentrates can be obtained with significantly higher amounts of active ingredients.

Diese Aufgabe wird durch die Bandschmiermittelkonzentrate gemäß Anspruch 1 gelöst.This object is achieved by the belt lubricant concentrates according to claim 1.

In den Unteransprüchen sind vorteilhafte Ausführungsformen der Erfindung enthalten.Advantageous embodiments of the invention are contained in the subclaims.

Die Erfindung betrifft daher Bandschmiermittel- oder Kettengleitmittel-Konzentrate auf Basis von Etherdiaminen bzw. deren Salzen (A) und/oder auf Basis von N-Alkyl-Dipropionaten (B).The invention therefore relates to tape lubricant or chain lubricant concentrates based on of ether diamines or their salts (A) and / or based on N-alkyl dipropionates (B).

Etherdiamine bzw. deren Salze der untenstehenden allgemeinen Formel (I) eigen sich erfindungsgemäß gut als Gleitmittel und lösen die obenerwähnten Probleme optimal: R-O-(CH2)k-NH-(CH2)1-NH2·(H+X-)m wobei
R ein substituierter oder unsubstituierter, linearer oder verzweigter, gesättigter oder einfach oder mehrfach ungesättigter Alkylrest mit 6 bis 22 C-Atomen ist, wobei die Substituenten ausgewählt sind aus Amino-, Imino-, Hydroxy-, Halogen- und Carboxy-Resten, oder ein substituierter oder unsubstituierter Phenylrest sind, wobei dann die Substituenten ausgewählt sind aus Amino-, Imino-, Hydroxy-, Halogen-, Carboxy-Resten und einem linearen oder verzweigten, gesättigten oder einfach oder mehrfach ungesättigten Alkylrest mit 6 bis 22 C-Atomen,
X- ein Anion einer anorganischen oder organischen Säure bedeutet,
k, l unabhängig voneinander eine ganze Zahl im Bereich von 1 bis 6 ist,
m eine ganze Zahl von 0 bis 2 ist, wobei das Schmiermittelkonzentrat 0,1 bis 100 Gew.% an Etheraminen der Formel (I) sowie 99 bis 0 Gew.% Wasser und/oder Hilfs-, bzw. Zusatzstoffe, jeweils bezogen auf die Gesamtformulierung, enthält. According to the invention, ether diamines or their salts of the general formula (I) below are well suited as lubricants and optimally solve the problems mentioned above: RO- (CH 2 ) k -NH- (CH 2 ) 1 -NH 2 · (H + X - ) m in which
R is a substituted or unsubstituted, linear or branched, saturated or mono- or polyunsaturated alkyl radical having 6 to 22 carbon atoms, the substituents being selected from amino, imino, hydroxyl, halogen and carboxy radicals, or a are substituted or unsubstituted phenyl radicals, the substituents then being selected from amino, imino, hydroxyl, halogen, carboxy radicals and a linear or branched, saturated or mono- or polyunsaturated alkyl radical having 6 to 22 carbon atoms,
X - is an anion of an inorganic or organic acid,
k, l is independently an integer in the range from 1 to 6,
m is an integer from 0 to 2, the lubricant concentrate 0.1 to 100% by weight of ether amines of the formula (I) and 99 to 0% by weight of water and / or auxiliaries or additives, in each case based on the Overall formulation, contains.

Die oben erwähnten Etherdiamine bzw. deren Salze der Allgemeinformel (I) können sowohl allein als auch in Kombination mit anderen Wirkstoffen bzw. Hilfs- und/oder Zusatzstoffen verwendet werden.The ether diamines mentioned above or their salts of the general formula (I) can be used alone as well as in combination with other active ingredients or auxiliaries and / or additives become.

Der Anteil der obenerwähnten Etherdiamine bzw. deren Salze an der Gesamtformulierung kann zwischen 0,1 und 100 Gew.% betragen.The proportion of the above-mentioned ether diamines or their salts in the overall formulation can be between 0.1 and 100% by weight.

X- kann ein Anion einer beliebigen anorganischen oder organischen Säure bedeuten. Von Bedeutung für die Auswahl dieser Säure im Sinne der vorliegenden Erfindung ist lediglich, dass die Säure bzw. deren Anion in Verbindung mit den erfindungsgemäßen Etheraminen der allgemeinen Formel (I) nicht zur Ausfällungen führt und damit die Wasserlöslichkeit des erfindungsgemäßen Schmiermittels beeinträchtigt. Bevorzugt werden zudem solche Säuren, welche Salze bilden, die bei Raumtemperatur und in wasserfreien Formulierungen flüssig sind oder sich durch Zugabe von relativ kleinen Mengen organischen Lösungsmittel verflüssigen lassen, denn erst diese Säure gestatten die Formulierung von hochkonzentrierten, wasserfreien oder beinahe wasserfreien Schmiermittelkonzentraten. Es ist außerdem von Vorteil, wenn überstöchiometrische Mengen Säure als Lösungsmittel für das gebildete Salz fungieren.X - can mean an anion of any inorganic or organic acid. It is only important for the selection of this acid in the sense of the present invention that the acid or its anion in conjunction with the ether amines of the general formula (I) according to the invention does not lead to the precipitation and thus impairs the water solubility of the lubricant according to the invention. Also preferred are those acids which form salts, which are liquid at room temperature and in anhydrous formulations or which can be liquefied by adding relatively small amounts of organic solvents, because only this acid allows the formulation of highly concentrated, anhydrous or almost anhydrous lubricant concentrates. It is also advantageous if excess stoichiometric amounts of acid act as a solvent for the salt formed.

Insbesondere können als Säure auch anionische Tenside wie die Ethercarbonsäuren bzw. die Phosphorsäureester der Fettalkoholethoxylate verwendet werden.In particular, anionic surfactants such as ether carboxylic acids or Phosphoric acid esters of fatty alcohol ethoxylates are used.

Diese Tenside können in den Formulierungen mehrere Funktionen ausüben:

  • Bildung von wasserlöslichen Etheraminsalzen,
  • pH-Regulierung,
  • Emulgatorfunktion,
  • Schmierwirkung.
These surfactants can perform several functions in the formulations:
  • Formation of water-soluble etheramine salts,
  • pH control,
  • emulsifier function,
  • Lubricating effect.

Diese Säuren können auch untereinander kombiniert werden, erfindungsgemäß bevorzugt werden z.B. Mischungen von Phosphatestern von Fettalkoholethoxylaten und Essigsäure.These acids can also be combined with one another, and are preferred according to the invention e.g. Mixtures of phosphate esters of fatty alcohol ethoxylates and acetic acid.

Weitere bekannten und bevorzugten Hilfs- bzw. Zusatzstoffen sind insbesondere:
Lösungsmittel wie Alkohole (z.B. Isopropanol, Ethanol), Glykole (z.B. 1,2-Propylenglykol), Fettsäureester (z.B. 2-Ethylhexylpalmitat; Decyloleat; Rapsöl-Methylester), zur Verbesserung der Homogenität bzw. zur Steuerung des Verdünnungsvorgangs bei der Anwendung.Other known and preferred auxiliaries and additives are in particular:
Solvents such as alcohols (e.g. isopropanol, ethanol), glycols (e.g. 1,2-propylene glycol), fatty acid esters (e.g. 2-ethylhexyl palmitate; decyl oleate; rapeseed oil methyl ester) to improve homogeneity or to control the dilution process during use.

Soweit eine biozide Wirkung des Bandschmiermittels gewünscht wird, kann man handelsübliche Biozide zusetzen. Hier besteht die Möglichkeit, die Biozide nach der besonderen Kundenanforderung zu wählen, wie z.B. formaldehydfreie Biozide, Wesenheit von Halogenen, usw. Es sind mehrere Biozide als Additive anwendbar, darunter allgemein bekannte Wirkstoffe, wie
5-Chlor-2-methyl-3-(2H)-isothiazolon,
2-Methyl-3-(2H)-isothiazolon,
1,2-Benzisothiazol-3(2H)-on,
2-Octyl-3-(2H)-isothiazolon;
3-Jod-2-propinylbutylcarbamat,
2-Pyridinthiol-1-oxid, Na-Salz
1,2-Dibrom-2,4-dicyanobutan
2-Brom-2-nitro-1,3-propandiol.If a band lubricant is desired to have a biocidal effect, commercially available biocides can be added. Here it is possible to choose the biocides according to the special customer requirements, such as formaldehyde-free biocides, the nature of halogens, etc. Several biocides can be used as additives, including well-known active ingredients such as
5-chloro-2-methyl-3- (2H) -isothiazolone,
2-methyl-3- (2H) -isothiazolone,
1,2-benzisothiazol-3 (2H) -one,
2-octyl-3- (2H) -isothiazolone;
3-iodo-2-propynyl butyl carbamate,
2-pyridine thiol-1-oxide, sodium salt
1,2-dibromo-2,4-dicyanobutane
2-bromo-2-nitro-1,3-propanediol.

Es können auch noch weitere Stoffe wie Formaldehydabspalter zugesetzt werden:Other substances such as formaldehyde releasers can also be added:

Dimethylolharnstoff
1,2-Ethandiylbis(oxy)]-bis-methanol,
3,3'-Methylen-bis[5-methyl-oxazolidin
1,3,5-Triazin-1,3,5(2H,4H,6H)-triethanoldimethylolurea
1,2-ethanediylbis (oxy)] - bis-methanol,
3,3'-methylene-bis [5-methyl-oxazolidine
1,3,5-triazine-1,3,5 (2H, 4H, 6H) -triethanol

Als thresholdaktive Substanzen können Phosphonate zur Stabilisierung gegenüber Wasserhärter eingesetzt werden. Komplexierungsmittel wie z.B. NTA dienen zur Stabilisierung gegenüber Wasserhärter.Phosphonates can be used as threshold-active substances to stabilize them against water hardeners be used. Complexing agents such as NTA serve to stabilize against Water hardness.

Als Emulgatoren eignen sich alle handelsübliche Emulgatoren, unabhängig von ihrem ionischen Charakter (anionische, nichtionogene, amphotere oder kationische Emulgatoren, allein oder in Kombination miteinander). Bevorzugt sind nichtionogene Emulgatoren wie z.B. Fettalkoholoder Fettsäureethoxylate bzw. die analogen Ethoxo-Propoxilate (sog. "EO-PO-Tenside"). Diese Emulgatoren sind in der Regel weitgehend unempfindlich in Bezug auf die Wasserhärte und pH-Wert. Bei geeigneter Auswahl sind sie gut biologisch abbaubar und enthalten weder Stickstoff noch Phosphor.All commercially available emulsifiers are suitable as emulsifiers, regardless of their ionic one Character (anionic, nonionic, amphoteric or cationic emulsifiers, alone or in Combination). Nonionic emulsifiers such as e.g. Fatty alcohol or Fatty acid ethoxylates or the analog ethoxo-propoxylates (so-called "EO-PO surfactants"). This Emulsifiers are generally largely insensitive to water hardness and pH. With a suitable selection, they are readily biodegradable and contain no nitrogen still phosphorus.

Voraussetzung ist allerdings, dass der Anteil an den N-Alkyl-Dipropionaminen der Formel (II) an der Gesamtformulierung mehr als 30 Gew.%, d.h. bis zu 100 Gew.% beträgt. Als geeignete Säuren für die Salze der N-Alkyl-Dipropionaminen gelten alle Säuren; deren Salze mit den betreffenden N-Alkyl-Dipropionaminen wasserlöslich sind und entweder selbstflüssig bei Raumtemperatur sind oder sich leicht verflüssigen lassen durch Zugabe von kleinen Mengen organischer Lösungsmittel.

As suitable acids all acids apply to the salts of N-alkyl dipropionamines; their salts with the concerned N-alkyl dipropionamines are water soluble and either self-liquid at room temperature are or can be easily liquefied by adding small amounts of organic Solvent. Acetic acid is particularly suitable here. In particular, anionic acids can also be used Surfactants such as ether carboxylic acid or the phosphoric acid esters of fatty alcohol ethoxylates be used.
