Definitions
- an aqueous lubricating concentrate for lubricating continuously moving conveyor systems wherein said concentrate contains a fatty acid soap and a surfactant, the improvement comprising the addition to said composition of monostearyl acid phosphate in an amount from about 0.15 to about 1.75 weight percent of the concentrate.
- the concentrate when diluted with water is then ready for use as a lubricating composition.
- the typical chain conveyor lubricant for convenience and economy in transporting and storing is manufactured and sold as a concentrate which is then diluted with water in proportions by volume of from about 1:50 parts concentrate to water to about 1:500 parts concentrate to water for usage.
- the lubricant concentrate typically consists of from about 20 to about 80 percent water, about 0 to percent sequestering agent, about 0 to 30 percent anionic surface active agent, about 2 to 40 percent fatty acid soap, about 0 to 40 percent coupling agent, about 0 to 15 percent nonionic surface active agent.
- the concentrate contain about 30 to about 70 percent water, about 2 to 15 percent sequestering agent, about 2 'to 30 percent anionic surface active agent, about 4 to percent fatty acid soap, about 0 to 20 percent coupling agent and about 2 to 10 percent nonionic surface active agent.
- monostearyl acid phosphate is added to the foregoing composition to obtain the objects of the present invention.
- the monostearyl acid phosphate is added in an amount from 0.15 to 1.75 percent of the concentrate exclusive of the water present. More preferably the amount of monostearyl acid phosphate will be from about onehalf to about 1.5 weight percent.
- sequestering agent salts of ethylene diamine tetracetic acid may be added to the composition in the form of the salts or the acid may be added along with a sufficient amount of metallic hydroxide or alkanolamine to neutralize the acid.
- sequestering agent which will complex calcium and magnesium ions from water may be employed in this invention.
- Additional suitable sequestering agents are trans-1,Z-diaminocyclohexane tetracetic acid monohydrate, diethylene triamine pentacetic acid, sodium salt of nitrilotriacetic acid, pentasodium salt of N- hydroxyethylene diamine triacetic acid, trisodium salt of N,N-di(beta-hyroxyethyl) glycine, and sodium salt of sodium glucoheptonate.
- Anionic surface active agents which may be employed include linear alkyl benzene sulfonic acids, alpha-olefin sulfonates, alkyl diphenyl oxide disulfonates, sodium N-methyl-N-alkyl-taurate, alkyl sulfonated amides, di(2-ethylhexyl) sulfosuccinate, dioctyl sodium sulfosuccinate, sodium sulfonate of oleic acid, anionic phosphate esters, alkyl ether sulfates, alkyl polyethyleneoxy esters, alcohol sulfates such as sodium lauryl sulfate, the product of chlorosulfonation of paraffin hydrocarbons, e.g., octadecenyl sulfonate and the condensate of a fatty acid chloride with an amine.
- fatty acid soap instead of adding fatty acid soap as such it is preferred to simply add fatty acid in amount from about 2 to 30 weight percent for the broad composition or 4 to 15 percent by weight in the preferred composition and then add a sufficient amount of an alkali metal (from the first column of the periodic table) hydroxide, ammonium hydroxide or an alkanolamine to neutralize the fatty acid to produce the fatty acid soap.
- an alkali metal from the first column of the periodic table
- ammonium hydroxide or an alkanolamine to neutralize the fatty acid to produce the fatty acid soap.
- the sequestering agent is also added in the acid form, the foregoing hydroxide or alkanolamine is added in sufficient amount to neutralize both the sequestering agent acid and the fatty acid.

- compositions of this invention are prepared by standard well-known open kettle mixing techniques known in the industry.
- a 12 foot section of continuous bottle conveyor driven by a one-third horse power motor is loaded with 50 water-filled 6.5 fluid ounce bottles.
- the test lubricating composition is diluted in a proportion by weight of 1:100. This dilute solution is then applied at a single application point at the end of the conveyor distal to the drive, thus simulating operating conditions of the section of the actual bottle conveyor.
- the relative efficiency of the lubricant is determined by the force in pounds of gate pressure exerted by the stationary bottles on a spring balance at the end of the conveyor as the chain moves under the load.
- compositions with poor lubricity will result in a higher gate pressure due to the force transmitted to the bottle column by the friction of the chain passing under the bottle load.
- a lubricant yielding a gate pressure of greater than 12 pounds on the balance with the standard load will exhibit poor lubricity under actual use conditions.
- the current load in watts of the drive motor is also proportional to the lubricity of the lubricant as related to the friction between the bottle load and the conveyor chain.
- the foam generating capacity of the test formula is determined by the height of the suds that build up between adjacent bottles. Lubricants giving a gate pressure of less than 12 pounds and an electricalload ofless than 105 watts have been shown to perform satisfactorily in actual conveyor systems. The results of lubricity and foam generating capacity of the below listed compositions are indicated in Table l below.
