Definitions
- the invention relates to a lubricant composition, and particularly to a lubricant composition comprising glycerol, water and carboxymethyl cellulose.
- Document WO 01/98441 discloses a conveyor lubricant composition comprising water, glycerol and carboxymethyl cellulose.
- Carboxymethyl cellulose may be used in a lubricant as thickener and tackiefier.
- a problem with the known lubricant comprising carboxymethyl cellulose is that the viscosity of carboxymethyl cellulose drops when the lubricant is in contact with iron, calcium, aluminum and/or oxygen. Lubricant is often stored in a stainless steel container or in some other container where it is in contact with air, which reduces the storage time of the lubricant significantly. When the viscosity drops, the thickening and tackifying effect of carboxymethyl cellulose is lost.
- An object of the present invention is to provide a lubricant composition so as to overcome the above problem.
- the invention is based on the idea of providing a lubricant composition comprising glycerol, water and carboxymethyl cellulose, wherein the composition further comprises sodium polyphosphate.

Description
- The invention relates to a lubricant composition, and particularly to a lubricant composition comprising glycerol, water and carboxymethyl cellulose.
- Document
WO 01/98441 - Carboxymethyl cellulose may be used in a lubricant as thickener and tackiefier.
- A problem with the known lubricant comprising carboxymethyl cellulose is that the viscosity of carboxymethyl cellulose drops when the lubricant is in contact with iron, calcium, aluminum and/or oxygen. Lubricant is often stored in a stainless steel container or in some other container where it is in contact with air, which reduces the storage time of the lubricant significantly. When the viscosity drops, the thickening and tackifying effect of carboxymethyl cellulose is lost.
- An object of the present invention is to provide a lubricant composition so as to overcome the above problem.
- The objects of the invention are achieved by a lubricant composition and use thereof which are characterized by what is stated in the independent claims. The preferred embodiments of the invention are disclosed in the dependent claims.
- The invention is based on the idea of providing a lubricant composition comprising glycerol, water and carboxymethyl cellulose, wherein the composition further comprises sodium polyphosphate.
- An advantage of the lubricant composition of the invention is that sodium polyphosphate surprisingly inhibits the reduction of the viscosity of the composition when the lubricant composition is in contact with iron, calcium, aluminum and/or oxygen.
- An advantage of the lubricant composition of the invention is also that sodium polyphosphate surprisingly lowers the pour point of the lubricant composition, which allows using the lubricant composition in lower temperatures.
- The invention relates to a lubricant composition comprising glycerol, water and carboxymethyl cellulose, wherein the composition further comprises sodium polyphosphate.
- In the lubricant composition, the purpose of the carboxymethyl cellulose is to increase the viscosity of the lubricant and the adhesion of the lubricant to the surface to be lubricated.
- In addition to inhibiting the reduction of the viscosity when the lubricant composition is in contact with iron, calcium, aluminum and/or oxygen, sodium polyphosphate also acts as a corrosion preventer.
