Definitions

  • This invention relates to a lubricant composition especially adapted for use as conveyor belt lubricant.
  • the traditional type of formulation for conveyor belt lubricants is based on fatty acid soap solutions, with or without other additives, such as sequestrants, surfactants, solvents, etc.
  • soap itself is a very good lubricant, it suffers from problems of excessive foaming in soft water, or of calcium soap precipitation in hard water, which may cause blockages in the automatic lubricant systems, especially in the nozzles.
  • high amounts of sequestrants have been used to soften the water, but under these conditions such formulations would again suffer from excessive foaming.
  • a further equally important requirement is that it should work under acid conditions. This is important, for example, in soft drinks bottling plants, where many products are acidic and will inevitably contaminate the conveyor, particularly in the vicinity of the bottle fillers.
  • the present invention now provides an improved lubricant composition suitable for use as a conveyor belt lubricant based on a simple and cost-effective formulation.
  • the lubricant composition of the invention is substantially free from a fatty acid soap and comprises:
  • the carboxylated nonionic and acyl sarcosinate mixture in the composition of the invention is neutralized to give a product pH of between 7 and 11, preferably between 8 and 9, particularly about 8.5.
  • Alkali hydroxides such as sodium hydroxide and potassium hydroxide, or alkanolamines, such as monoethanolamine or diethanolamine, are examples of suitable neutralizing agents.
  • the weight ratio of carboxylated nonionic to acyl sarcosinate in the composition of the invention is from about 2:1 to 1:2.
  • a preferred ratio is 3:2, which will give a product suitable for use in a wide range of water hardness, i.e. from zero to 3 mol m- 3 .
  • the degree of alkoxylation (n) in the carboxylated nonionic molecule is important.
  • a lower degree of ethoxylation causes an improvement in lubricity and a further reduction in foam, but at the expense of the composition becoming more sensitive to hard water.
  • the degree of ethoxylation therefore should not be lower than 3.
  • a higher degree of ethoxylation causes a reduction in lubricity and an increase in foam.
  • the degree of ethoxylation therefore should not be higher than 7.
  • a preferred carboxylated nonionic is:
  • a preferred acyl sarcosinate is oleyl sarcosinate having the formula:
  • a conventional nonionic surfactant compound particularly a low-foaming nonionic surfactant.
  • the incorporation thereof will have the effect of improved detergency, which can be of importance, e.g. in dairies.
  • nonionic surfactants examples include in particular the liquid reaction products of ethylene oxide with C 6 ⁇ C 12 alkyl phenols or with aliphatic (C 8 ⁇ C 18 ) primary or secondary linear or branched chain alcohols; and products made by condensation of ethylene oxide with propylene oxide or the reaction products of propylene oxide and ethylene diamine.
  • nonionic surfactants include long chain tertiary amine oxides and long chain tertiary phosphine oxide.
  • Nonionics having an HLB value of from 10-12, preferably from 10.5-11, are particularly suitable, such as nonyl phenol condensed with 5-6 ethylene oxide groups (NP/5-6 EO).
  • the lubricant compositions of the invention are preferably presented in liquid form. These liquids will generally comprise about 5-20% by weight of the active components (a) and (b), i.e. carboxylated nonionic and acyl sarcosinate, together. Higher active mixture contents may be presented as viscous liquid or paste-like products.
  • composition of the invention is normally diluted with water to an active concentration of about 150-750 mg/liter.
  • active concentration of about 150-750 mg/liter.
  • a dilution of from about 0.1-0.5% is normally applied.
  • composition 1 of the invention and the commercial products were tested at various use concentrations and diluted with water of various degrees and hardness, for frictional drag (measure of lubricity), solution appearance and foam.
  • Jetloob and Zefa gave clear solutions in totally soft water (tests d and h). They would not cause jet blocking problems and could be used at low concentrations; unfortunately, however, they both foam excessively and therefore are unsuitable.
  • the Composition 1 of the invention was clearly superior to both commercial products Jetloob and Zefa in both hard and soft water.
  • Example I The composition I of Example I was also tested over a two-week period at various use concentrations in a problem area (relatively tall bottles with narrow bases). No problems were encountered at use concentrations down to 0.2% in soft water. The conveyors were noticeably cleaner with this product than with the soap-based products of the art.
  • compositions IV-V are usable for soft water.
