Benefits of technology

Surprisingly, it has been discovered that a high concentration non-solid fatty acid lubricant composition can be prepared using a fatty acid, a neutralizer, a polyalkylene glycol polymer, and a monomeric polyol. Such compositions provide the benefits of requiring less storage space while being able to use dispensing equipment normally used for dispensing liquid lubricants onto a conveyor. In addition, such non-solid fatty acid compositions also provide some detergency benefits. Further, they have the ability to be made out of food additive ingredients which is beneficial in the food and beverage industry. Finally, they can serve as a booster for lubricants that are traditionally used on PET lines. By acting as a booster, the compositions of the invention allow a plant to maintain a large supply of PET lube that is used for both PET lines and other lines such as can lines, and a smaller tank of the compositions of the invention, which may be added only to the can lines to provide additional lubricity as well as the other benefits, such as detergency.

Problems solved by technology

However, liquid lubricants require a large volume of storage space.
However, high concentration fatty acid compositions are difficult to make.

example 1

examined the impact of various additives on the viscosity of a high concentration fatty acid composition. For this example, four formulas were prepared (see Table 3).

Table 3 shows that the combination of polyalkylene glycol (50HB660) and monomeric polyol (propylene glycol) is necessary to achieve a concentrated fatty acid composition with a low viscosity (easy flow). Formula 1 contained only polyalkylene glycol polymer without the monomeric polyol. The resulting composition solidified. Formula 2 contained only the monomeric polyol without the polyalkylene glycol polymer. The resulting composition was very thick having a viscosity of 7550 c...

example 2

Example 2 determined the impact of the choice of polyalkylene glycol on viscosity. For Example 2, hexylene glycol was used as the monomeric polyol. The polyalkylene glycol in Example 1, 50HB660 was replaced with 50HB55, LB285 and Carbowax 300. The formulas used for this example are listed in Table 4, along with the viscosity results and product observations. The formulas are listed as weight percents.

Example 3 determined the impact of the choice of monomeric polyol on viscosity. Ucon 50HB600 was used as the polyalkylene glycol polymer and propylene glycol, ethylene glycol, hexylene glycol, and ethyl alcohol were used as the monomeric polyols. The formulas used for this example are listed in Table 5, along with the viscosity results and product observations. The formulas are listed as weight percents.

Abstract

A composition and method of lubricating conveyor tracks or belts is herein described wherein the lubricant composition contains a fatty acid, a neutralizing agent, a polyalkylene glycol polymer and a monomeric polyol; also described are methods of manufacture of such lubricant compositions. The compositions may also comprise additional functional ingredients.

Description

FIELD OF THE INVENTION The invention pertains to a lubricant suitable for use on a conveyor system and a method of making and using such lubricant. More particularly, the invention pertains to a non-solid conveyor lubricant composition having a high fatty acid concentration, and methods of making and using the same. BACKGROUND In many industries, including, for example, the food and beverage processing industry, containers and other articles are transported from one location to another location by conveyors such as belt conveyors. In many such conveyor systems, a lubricating composition is used on the conveyor. One of the reasons that a lubricating composition is used is to facilitate movement and reduce the damage to the container resulting from mechanical impact between the containers and the rubbing action among the containers and between the containers and the belt. For example, occasionally in such systems, the containers are stopped on the conveyor due to a back up on the co...
