Definitions
- Lubricant composition based on natural and renewable
- the invention relates to a lubricant composition based on modified, natural and renewable raw materials whose viscosity is adjustable depending on the application.
- the invention relates to biodegradable lubricant compositions.
- 4,327,030 A describes a process for the modification of triglyceride-based native oils, these being reacted with peroxide at a temperature of 100 to 200 ° C.
- the polymerized polyunsaturated fatty acid esters are separated in the remaining residue and disposed of.
- the process serves to reduce the content of linoleic acid in order to increase the content of oleic acid. An oil with a higher proportion of oleic acid is thus obtained.
- An object of the present invention is to provide a lubricant composition based on triglyceride-based native, renewable oils to which viscosity can be adjusted according to the desired application.
- Another object of the present invention is to provide a lubricating composition containing the modified native oils which can be used at extreme temperatures in high and low temperatures Low temperature range has good tribological properties and good resistance to oxidation.
- a lubricant composition in which native oils based on triglycerides are reacted with peroxides and the unsaturated fractions of the fatty acids are linked together by means of a radical addition reaction. This reaction alters the viscosity of the modified oil.
- the viscosity can be adjusted to the desired value as a function of the peroxide / oil ratio and thus adapted to the requirements of the particular application.
- the lubricant composition can be used as fluid grease of NLGI grades 000, 00 and as fluid grease for central lubrication systems and in the context of gear lubrication and as so-called soft grease in plain bearings, rolling bearings and water pumps of NGLI grades 1 to 4 or so-called Tough greases of NLGI grades 5 and 6 can be used as sealing or block greases.
- Basis for the lubricant compositions of the present invention is a method for changing the viscosity of a triglyceride-based native oil, wherein the native oil is reacted with a peroxide compound at a temperature of 165 ° C to 19O 0 C for 3 to 5 hours and then the unsaturated double bonds be linked by radical addition reaction. Subsequently, the by-products formed during the polymerization are removed under high vacuum. The viscosity-modified oils produced in this way can then be further processed in situ for the production of lubricants. Depending on the desired viscosity of the oil to be produced, 4.8% to 10.3% of the corresponding peroxide compound is used for the reaction of the native oil with the peroxide compound.
- Fig. 1 shows the dependence of the viscosity of the peroxide concentration. Due to the different amounts of peroxide compound so a highly viscous oil as well as a low viscosity oil can be produced in a simple manner reproducible.

Compared to mineral oils they have the advantage that they are biodegradable and are available indefinitely.
- the unsaturated fatty acids are wholly or partly linked to one another by the reaction with peroxide via a radical addition reaction by utilizing the unsaturated components in the oils.
- the degree of polymerization of the modified oil is dependent on the ratio of the oil to the peroxide. Another influence on the degree of polymerization, the reaction temperature and the reaction time.
