Definitions

  • the present invention relates to a lubricant concentrate composition and more particularly to a lubricant composition obtainable on diluting such a concentrate, which compositions have biocidal activity.
  • Slat conveyor systems such as used in industrial bottle washing systems, need to be lubricated in order to ensure smooth running.
  • Conveyor belt lubricants based on diamines are already known from for instance EP-A-372,628. Such lubricants use acetic acid to solubilise the diamines. However a problem here is that at low pH, lubrication is lost. The inventors have found that on replacing acetic acid with a quaternary ammonium compound, and in particular didecyl dimethyl ammonium chloride, an effective lubricant is provided.
  • the level of diamine compounds in the lubricant composition can be reduced without substantially effecting activity, whereby a low-foaminf lubricant, which can be easily washed away, is provided.
  • a lubricant concentrate composition according to claim 1 which can be diluted to a lubricant composi ⁇ tion.
  • a method of lubricating a system such as a bottle washing or a conveyor belt system, comprising the steps of diluting the lubricant concentrate composition of the invention and passing the resulting diluted lubricant through the system.
  • a lubricant composition obtainable by diluting the lubricant concentrate composition of the present invention, with water to a suitable use concentration.
  • the diluted lubricant composition is a 0.2 - 0.4% by weight aqueous solution of the lubricant concentrate composition of the invention.
  • the present invention provides the use of a lubricant composition of the invention for lubricating a bottle washing system or a conveyor belt system.
  • lubricant compositions according to the present invention Since the need to add a relatively large amount of acid to solubilise the diamines is obviated in lubricant compositions according to the present invention, substantially all the diamine becomes available for lubrication. Since, in comparison with known lubricants, the lubricants according to the present invention are more alkaline, they therefore yield protection against acidic spillages.
  • a further advantage of the lubricant compositions according to the present invention is that they overcome this problem of the formation of bio-films by providing an effective biocidal activity, whereby bio-organisms are prevented from growing in the system, and any such organisms already in the system are killed.
  • the lubricant concentrate composition of the invention preferably comprises from 1 to 5% by weight of each diamine compound present therein. More preferably, the concentration of each diamine compound is in the range of from 1 to 2% by weight.
  • the diamine compounds present in the lubricant composition of the invention are preferably selected from the group consisting essentially of N-oleyl-1, 3-diaminopropane and N- coco-1,3-diaminopropane, these giving effective results.
  • the concentration of the quaternary ammonium compound present in the lubricant concentrate composition is preferably in the range from 4 to 10% by weight, more preferably from 5 to 6% by weight.
  • the quaternary ammonium compound preferably has the general formula
  • didecyl dimethyl ammonium chloride offers the following advantages: - the pH range over which both lubricity and disinfec ⁇ tion (biocidal activity) are achieved when applying this quaternary ammonium compound in the composition of the invention, is wider than that achieved with known lubricants of the prior art -such as those disclosed by EP-A-372, 628, the upper pH limit being about 10 according to the present invention; - the sensitivity to anions in dilution water is sub ⁇ stantially reduced with respect to known lubricants, in other words the inventors have found a considerable improvement in the field of lubricants based on diamines, which are known to be susceptible to precipitation from use solutions containing high levels of anions, especially sulphates;
  • compositions according to the present invention containing this type of quaternary ammonium compound are reduced whereby environmental loading and effluent treatment costs are reduced
  • the lubricant composition of the invention preferably further comprises an acid, desirably acetic acid.
  • concentration of said acid in the concentrate composition is effectively in the range of from 0.01 to 1% by weight.
  • said composition preferably further comprises a nonionic agent, the concentration of which being effectively in the range of from 0.1 to 5% by weight based on the concentrate composition.
  • Said nonionic agent is preferably oleylamine ethoxylate.
  • a further optional and preferred component of the lubricant composition is a detergent builder, which is preferably triethanolamine .
  • the concentration of said builder preferably lies in the range of from 0.1 to 5% by weight based on the concentrate composition.
  • the present invention is illustrated by way of the following example, in which % is by weight unless otherwise indicated.
  • a lubricant concentrate was formulated having the following composition:
  • This concentrate composition was diluted with water to a 0.3 wt% dilute lubricant composition.

Abstract

L'invention concerne une composition concentrée de lubrifiant contenant une ou plusieurs diamines et un ou plusieurs composés ammonium quaternaire ou des sels solubles de ceux-ci. L'invention concerne, également, un procédé pour lubrifier un système, par exemple une installation de lavage de bouteilles ou un transporteur à bande, consistant à diluer la composition concentrée de lubrifiant de l'invention et à faire passer le lubrifiant dilué résultant dans le système. L'invention concerne, en outre, une composition lubrifiante que l'on obtient en diluant la composition concentrée de l'invention avec de l'eau jusqu'à avoir une concentration d'utilisation convenable.
