Description

    FIELD OF THE INVENTION
  • This invention relates generally to an aqueous conveyor and cutting lubricant that demonstrates greatly improved lubricity, and more particularly relates to a lubricant that employs a combination of polyamines, and an alkoxylated alcohol nonionic surfactant. The present invention may be used to lubricate conveyor chains in bottling plants and canneries, and may be applied directly to saw blades, files and cutters.
  • BACKGROUND AND SUMMARY OF THE INVENTION
  • In bottling plants, containers to be filled (e.g., glass and plastic bottles) are transported by conveyors such as platform conveyors or chain-like arrangements, generally referred to as chain conveyors. The different stages in the bottling process such as, for example, bottle washing, filling, closing, labeling, and packing, are connected by way of these chain conveyors. In order to assure uninterrupted operation, the conveyor chains have to be suitably lubricated to avoid excessive friction with the containers. Lubricants containing suitable friction-reducing ingredients are normally used for this purpose. The chain conveyors are typically contacted with the lubricants by dipping or spraying. As will be readily appreciated by those skilled in the art, inadequate lubrication of chain conveyors, which are known to adopt somewhat tortuous paths within bottling plants, tends to cause containers such as glass bottles to fall off the conveyors and break.
  • Lubricants including certain amine compounds are known. For example, U.S. Pat. No. 5,900,392 to Laut Bernhard describes an aqueous belt lubricant composition that is formulated as a dilutable concentrate. The dilutable concentrate basically comprises:
      • (a) water;
      • (b) from 1.0 to 20 wt. % of at least one fatty alkyl propylene tetramine;
      • (c) from 1.0 to 10 wt. % of at least one fatty alcohol polyglycol ether; and
      • (d) at least one acid in an amount sufficient to establish a pH value between about 5 and about 7.
  • The fatty alcohol polyglycol ether reportedly acts as an antifoaming agent in the aqueous belt lubricant composition, with most preferred chain length distributions for the alkyl group of the fatty alcohol being identified as C12 to C14 or C16 to C18 alkyl groups.
  • Dilutable concentrates formulated in accordance with the teachings of U.S. Pat. No. 5,900,392 have been found to have relatively short shelf lives, separating after only one to three months in storage. Moreover, suitable lubricity has been achieved by the disclosed belt lubricant composition only at relatively high dilution ratios of about 1:250 or 0.4%.
  • By way of the present invention, a dilutable concentrate with extended shelf life for use in preparing an aqueous conveyor and cutting lubricant that demonstrates greatly improved lubricity, is provided.
  • The present invention more particularly provides a dilutable concentrate that comprises: a combination of tallow di-, tri- and tetramines; at least one acid in an amount sufficient to establish a pH value of from about 3.0 to about 6.0; an alkoxylated alcohol nonionic surfactant; balance water.
  • In a preferred embodiment, the inventive dilutable concentrate comprises:
      • (a) water;
      • (b) from about 3 to about 45% by wt., based on the total weight of the dilutable concentrate, of a combination of tallow di-, tri- and tetramines;
      • (c) from about 3 to about 12% by wt., based on the total weight of the dilutable concentrate, of at least one organic acid;
      • (d) from about 1 to about 10% by wt., based on the total weight of the dilutable concentrate, of an alkoxylated alcohol nonionic surfactant comprising a condensation product of one or more alkylene oxides with one or more fatty alcohols having alkyl chains of less than 12 (preferably, from 6 to 10) carbon atoms;
      • (e) optionally, an effective amount of one or more antimicrobial compounds; and
      • (f) optionally, an effective amount of one or more cationic surfactants.
  • In a more preferred embodiment, the inventive concentrate comprises:
      • (a) water;
      • (b) from about 1 to about 15% by wt. (preferably, from about 2 to about 8% by wt., more preferably, from about 2 to about 5% by wt.), based on the total weight of the dilutable concentrate, of a tallow diamine;
      • (c) from about 1 to about 15% by wt. (preferably, from about 2 to about 8% by wt., more preferably, from about 2 to about 4% by wt.), based on the total weight of the dilutable concentrate, of a tallow triamine;
      • (d) from about 1 to about 15% by wt. (preferably, from about 2 to about 8% by wt., more preferably, from about 4 to about 6% by wt.), based on the total weight of the dilutable concentrate, of a tallow tetramine;
      • (e) from about 3 to about 12% by wt. (preferably, from about 4 to about 8% by wt., more preferably, from about 5 to about 8% by wt.), based on the total weight of the dilutable concentrate, of glacial acetic acid;
      • (f) from about 1 to about 10% by wt. (preferably, from about 2 to about 6% by wt., more preferably, from about 3 to about 5% by wt.), based on the total weight of the dilutable concentrate, of a C6 to C10 linear alcohol alkoxylate (i.e., a C6 to C10 fatty alcohol polyglycol ether) nonionic surfactant;
      • (g) from about 0 to about 5% by wt. (preferably, from about 0.5 to about 2% by wt., more preferably, from about 1 to about 2% by wt.), based on the total weight of the dilutable concentrate, of an isothiazolin-3-one antimicrobial compound; and
      • (h) from about 0 to about 5% by wt. (preferably, from about 1 to about 4% by wt., more preferably, from about 1 to about 3% by wt.), based on the total weight of the dilutable concentrate, of a quaternary ammonium compound cationic surfactant.

  • BEST MODE FOR CARRYING OUT THE INVENTION
  • As alluded to above, by way of the present invention, the inventors have made the surprising discovery that the use of a combination of polyamines, and an alkoxylated alcohol nonionic surfactant in a dilutable concentrate used to prepare an aqueous conveyor and cutting lubricant effects a surprising and unexpected increase in the lubricating properties demonstrated by the lubricant.
  • The aqueous conveyor and cutting lubricant of the present invention can be used on stainless steel and plastic conveyor chains in bottling plants and canneries, and demonstrates greatly improved lubricity when used with beverage and food containers such as aluminum cans, glass bottles, and PET containers. The inventive lubricant may also be applied directly to saw blades, files and cutters.
  • In addition to the greatly improved lubricating properties demonstrated by the conveyor and cutting lubricant of the present invention, the inventive lubricant is low foaming and has good cleaning, dispersant and lubricating properties that are unaffected by water hardness. In addition, the inventive dilutable concentrate demonstrates increased shelf life in that the concentrate will not separate even when stored for periods of more than three (3) months.
  • In a preferred embodiment, the inventive lubricant is antimicrobial or biocidal, thereby serving to, among other things, reduce or prevent formation of black slime on conveyor chains and nozzle blockage due to polysaccharide formation.
  • As noted above, the inventive lubricant is prepared from a dilutable concentrate that comprises: a combination of tallow di-, tri- and tetramines; at least one acid in an amount sufficient to establish a pH value of from about 3.0 to about 6.0; an alkoxylated alcohol nonionic surfactant; balance water.
