Definitions

  • the present invention relates to the use of ethoxylated fatty alkyl diamines or triamines as lubricants, in particular chain lubricants.
  • Lubricants are used to coat surfaces of different materials, such as metal, glass etc. with a film and to minimize friction, for example in conveyor belts in filling systems (chain lubricants). Soaps, in particular potash-based soaps, are frequently used as chain lubricants, but they have the disadvantage of forming poorly soluble precipitates with cations, predominantly with the calcium ions present in hard water.
  • soaps for use as chain lubricants are amines, as described, for example, in US Pat. Nos. 4,839,067, 4,521,321, 4604,720 and AU-A-10004/83. These are insensitive to cations, but with anions such as carbonate or sulfate ions they form precipitates which impair the sliding action.
  • EP-A-0 372 628 discloses the use of diamines which are not alkoxylated as chain lubricants.
  • the document also discloses the use of alkoxylated diamines as dispersants in amounts of 0 to 1 wt .-%.
  • the document contains no indication that the alkoxylated diamines are suitable as lubricants.
  • the task was therefore to develop high-performance lubricants which are insensitive to anionic and cationic salt-like components, such as calcium, sulfate and carbonate ions, but which should have a comparable lubricating effect.
  • aqueous solutions containing ethoxylated di- and / or triamines have excellent chain lubricants reduced tendency to form precipitation. They also have a desired antimicrobial effect.
  • the invention thus relates to the use of compounds of the formula 1
  • R 1 is linear or branched C 8 -C 22 alkyl or alkenyl
  • R 2 is hydrogen, a radical of the formula - (AO) x -H or a radical of the formula
  • -R 3 denotes -N [(AO) x H] 2 , in which A represents C 2 -C 4 alkylene,
  • R 3 is linear or branched C 8 alkylene
  • R 4 and R 5 either both represent hydrogen or both represent a radical of the formula - (AO) x -H, x each represents an integer from 1 to 10, with the proviso that the
  • Compounds of formula 1 contain at least 2 groups of formula (A-O).
  • R 1 is linear or branched C10-C 20 -, in particular linear or branched C 2 -C 8 -alkyl.
  • A preferably represents an ethylene group.
  • R 3 preferably denotes a linear or branched C 1 -C 4 alkylene group.
  • R 4 and R 5 are preferably a radical of the formula (AO) x -H.
  • the degree of alkoxylation x can assume different values at the 3 alkoxylated positions.
  • the total degree of alkoxylation, ie the sum of all alkoxy units, is an integer between 3 and 10.
  • compounds of the formula 3 are used as lubricants.
  • R 1 , A and R 3 have the meaning given above.
  • the degree of alkoxylation x can assume different values at the 4 alkoxylated positions.
  • the total degree of alkoxylation is an integer between 4 and 15.
  • More than one compound of formula 1 can also be used.
  • the aqueous preparations used according to the invention can contain further additives customary for lubricants, for example further fatty alkylamines, acids such as acetic acid for pH adjustment, dispersing agents, solvents or solubilizers, sequestering agents, antimicrobial agents, etc.
  • further additives customary for lubricants for example further fatty alkylamines, acids such as acetic acid for pH adjustment, dispersing agents, solvents or solubilizers, sequestering agents, antimicrobial agents, etc.
  • Low tendency towards precipitation, little foaming and good antimicrobial properties of the aqueous preparations used according to the invention make it possible to keep the addition of further additives low.
  • the cleaning of plants in which the composition according to the invention is used is only necessary at large time intervals.
  • organic acids for example formic acid, acetic acid, glutaric acid
  • the acid (s) preferably 0.001% by weight to 1% by weight, in particular 0.005% by weight to 0.1% by weight, of acid, based on the aqueous preparation, is added.
  • Organic solvents preferably monohydric or polyhydric alcohols with 1 to 8 carbon atoms, in particular isopropanol, ethanol, glycols, such as ethylene glycol, propylene glycol, hexylene glycol, can be used in amounts of 0 to 20% by weight, preferably 0.01 to 10% by weight .-%, based on the finished agent used.
  • Dispersants for example triethanolamine, are preferably added to the aqueous lubricants in the amounts by weight of 0 to 1%, in particular 0.001 to 0.5%, particularly preferably 0.005 to 0.1%.
  • the lubricants are preferably produced as concentrates with 1 to 30% by weight of the compounds of the formula 1, based on the finished composition, and immediately before use with water or water-miscible solvents, such as ethanol, isopropanol, glycols or mixtures of these solvents and water, diluted.
  • water or water-miscible solvents such as ethanol, isopropanol, glycols or mixtures of these solvents and water, diluted.
  • aqueous solutions were prepared from the amines of Examples 1 to 4 and were neutralized with acetic acid.
  • the concentrate thus obtained was diluted 1: 300 by volume with tap water.
  • the comparative soap-based lubricant was diluted with demineralized water.
  • the application-related testing of the sliding properties was carried out by measuring the pressure that a certain number of bottles exerts on a permanently installed balance on a bottle conveyor belt that was lubricated with the lubricant to be tested.
  • the measured value obtained in grams is a measure of the friction of the bottle conveyor belt on its guide. The lower the measured value, the lower the friction. Measured values for the friction as a function of time and pH were recorded.
