Description

  The present invention relates to high temperature lubricants, in particular aromatic esters such as trimellitic esters and mixtures of various trimellitic esters, alkylaromatic compounds, estrides and fully hydrogenated or hydrogenated polyisobutylenes. Or oils and greases based on thickeners, or mixtures thereof. The invention further relates to the use of this high temperature grease at continuous use temperatures of up to 250 ° C.

  In addition to lubrication, the lubricant also needs to meet a number of further challenges: the lubricant cools, reduces friction, wear, and stress transmission, protects against corrosion, and at the same time has a sealing action There is a need. Furthermore, it is desirable that these high temperature greases have low acoustics.

  Conventional lubricants are not suitable for high temperature applications. This is because they are destroyed at high temperatures by, for example, oxidation and / or pyrolysis reactions and polymerization, and their lubricating properties are greatly limited. In the decomposition reaction, the lubricant is decomposed into low molecular volatile components. This evaporation results in unwanted viscosity changes, oil loss, and excessive vapor formation. Thereby, the lubricating action is lost. Also by polymerization, the lubricant loses its lubricating action by forming an insoluble polymerization product.

  Removing these contaminants increases maintenance work and generates chemical waste that must be costly treated. The downtime increases because of increased cleaning and maintenance work. Overall, the use of unsuitable lubricants in high temperature applications results in higher costs. This is because the work equipment is contaminated and more lubricant is needed. In addition, product quality is reduced.

  Synthetic esters are often used as base oils for high temperature applications. This is because they have very good oxidative stability, hydrolytic stability, and thermal stability.

  In order to meet the various requirements in high temperature applications, the lubricant must have, inter alia, high stability, low coefficient of friction, and high wear strength. In order to ensure uniform lubrication even at high temperatures, a liquid lubricating film must be present between the metal members during the entire processing process. Therefore, the lubricant should evaporate only slightly at the maximum processing temperature and not form too much residue, and should form as little decomposition residue as possible.

  High processing temperatures are often found in chains, rolling and sliding bearings, in automotive technology, transportation technology, mechanical engineering, office technology, and in industrial equipment and machinery, and in the field of household equipment and household appliances. Occurs in the use of.

  In a rolling bearing and a sliding bearing, a lubricant transmits a stress transmission lubricating film that separates parts that slide or roll from each other. For this reason, the metal surfaces do not contact each other, and therefore wear does not occur. Thus, the lubricant must meet high demands. The requirements include extreme conditions such as very high or very low rotational speeds, high speeds conditioned by high rotational speeds or external heating, very low temperatures such as the temperature of bearings operating in cold surroundings, or aviation And there are temperatures that arise from use in space flight. Similarly, it is desirable that modern lubricants can be used under so-called clean room conditions in order to avoid space contamination due to wear or lubricant consumption. Furthermore, when applying modern lubricants, the lubricant will evaporate and thereby "varacken", i.e. the lubricant becomes solid after a short application and no longer exhibits a lubricating effect. It is desirable to avoid this. Lubricants are also special during application so that the sliding surface of the bearing is not attacked with little friction, so that the bearing surface slides with less acoustics, and long sliding times are achieved without subsequent lubrication. Demands. The lubricant must also withstand the effects of stress, such as centrifugal force, gravity, and vibration.

An important parameter for the long functional time of rolling bearings lubricated with grease in the high temperature range is the acoustic properties of the lubricant, in addition to the operating temperature. Lubricating grease may induce vibrations in rolling bearings when involved in rotation (rolling (Webrolling), mixing (Walking)), and this vibration as "lubricant sound" Compared to being in the low frequency band of ˜300 Hz, it is in the medium frequency band of 300 to 1,800 Hz and in the high frequency band of 1,800 to 10,000 Hz. Lubricant acoustics overlap with acoustic peaks that occur in the bearing ring in the form of shock pulses as the hard particles roll by the rolling elements. The acoustic characteristics are evaluated according to the SKF-BeQuiet ⁺ method. Grease acoustic grades are classified as follows:
GNX: Slightly worse than GN1 (very poor acoustic properties)
GN1: More than 95% of all peaks are 40 μm / s or less (poor acoustic characteristics)
GN2: More than 95% of all peaks are 20 μm / s or less; more than 98% of all peaks are 40 μm / s or less (average acoustic characteristics)
GN3: more than 95% of all peaks are 10 μm / s or less; more than 98% of all peaks are 20 μm / s or less; more than 100% of all peaks are 40 μm / s or less (good acoustic characteristics)
GN4: more than 95% of all peaks are 5 μm / s or less; more than 98% of all peaks are 10 μm / s or less; more than 100% of all peaks are 20 μm / s or less (very good acoustic characteristics).

  The better the acoustic properties of the lubricating grease, the less vibration of the bearing caused by the lubricant. This is synonymous with less bearing load and leads to longer bearing function time.

  Accordingly, an object of the present invention is to provide a high temperature oil and a high temperature grease that meet the above requirements. In particular, it is desirable that the lubricating oil or the lubricating grease exhibits a good lubricating action at a high temperature for a long period of time. Furthermore, it is desirable that the decomposition residue formed is not varnished but can be dissolved again with new grease. Furthermore, it is desirable that the high temperature lubricants have good hydrolytic stability, are corrosion and wear resistant, and have good oxidation resistance and good low temperature properties that meet the requirements. This is defined by the pour point in the case of lubricating oil and by the flow pressure at low temperature in the case of lubricating grease. Furthermore, it is desirable that the high temperature grease exhibits good acoustic properties, has a long duration, and does not substantially cause equipment wear phenomena.

The figure which shows the friction characteristic of the oil which is measured in accordance with DIN 51834-2 in SRV Diagram showing evaporation loss measured in dynamic TGA

Example 1-2
Production of high temperature oil according to the invention Estoride or aliphatic substituted naphthalene is pre-charged into a stirring vessel. While stirring at 100 ° C., add polyisobutylene and possibly further oil. The mixture is subsequently stirred for 1 hour to obtain a homogeneous mixture. Antiwear and antioxidant are placed in the kettle with stirring at 60 ° C. After about 1 hour, the finished oil can be transferred to a prepared container.

Basic data for the oil examples can be obtained from Table 3.

Furthermore, the friction properties of the oil were measured in SRV according to DIN 5834-2, and the evaporation loss was measured in a dynamic TGA. These results are shown in Tables 4 and 5 and further illustrated in FIGS.

Example 3-8
Production of high-temperature grease according to the present invention The base oil is charged in advance into a stirring vessel. While stirring at 100 ° C., add polyisobutylene, and optionally additional oil, and thickener. Thickeners are formed by reacting in situ the reactants used in the base oil. Subsequently, the mixture is heated to 150-210 ° C., stirred for several hours and cooled again. In the cooling process at about 60 ° C., the necessary antiwear, antioxidant and anticorrosive agents are added. A homogenous mixture of greases is obtained by a homogenizing process of finishing with rollers, colloid mills or Gaulin.

The composition of the high temperature grease is shown in Table 6.

The thickener used in Examples 3-8 is
Example 3: LiOH, 12-hydroxystearic acid, azelaic acid,
Example 4: LiOH, 12-hydroxystearic acid, azelaic acid,
Example 5: LiOH, 12-hydroxystearic acid, azelaic acid,
Example 6: Diurea; methylene-diphenyl-diisocyanate (MDI), octylamine, oleylamine Example 7: Diurea; MDI, octylamine, oleylamine Example 8: Diurea; MDI, octylamine, oleylamine.

Table 7 shows general parameters of the grease samples 3-8.

  After 30 hours at 150 ° C., the evaporation loss rate of the various grease samples is between 2% and 5%, which emphasizes that the thermal stability of this grease design is very good.

  It is the degree of oil separation that has a decisive influence on the lubricating action of grease. Note that the oil separation is not too high and the oil flows from the bearing and is therefore not used in the friction system, while the oil lubrication is lost without any oil separation. To do. The oil separation degree is ideally 0.5 to 8% by mass so that an optimum lubricating film can be formed in the bearing.

  The greases of the examples are subjected to the FE9 rolling bearing test according to DIN 51821, in which the life of the grease investigated is determined and the upper working temperature of the lubricating grease is determined by the average speed and the average axial load. Specified for rolling bearings.

The greases investigated and the results of the L10 and L50 values are shown in Table 8.

  Table 8 shows that the duration is increased by using PIB in combination with various base oils and is therefore suitable for high application temperatures in long-term operation.

Furthermore, the acoustic properties of the grease were measured for Examples 3-8 according to SKF Be Quiet ⁺ . These results are listed in Table 9.

  The acoustic properties of the various grease preparations are very beneficially influenced by using fully hydrogenated polyisobutylene. Except for Example 6, good to very good acoustic characteristics can be obtained.

Fully hydrogenated PIB properties of the grease according to Example 3 was used, PIB that were present yet double bond, and grease (Comparative Example 3) containing the PIB that are not knob Rimizu fluorinated comparison did.

The other composition of the grease according to Comparative Example 3 corresponded to the composition of Example 3.

In Table 10, comparison of the grease, and fully hydrogenated PIB Oyo PIB that are not beauty water fluorination is grease of Example 3, showed twice the duration in FE9 test, less evaporation loss And a remarkably good acoustic characteristic.

In order to demonstrate the advantageous properties of an oil containing fully hydrogenated PIB, it was compared to an oil containing partially hydrogenated PIB. Table 11 shows the results.

  Table 11 shows that there is a clear difference between using fully hydrogenated PIB and using partially hydrogenated PIB. That is, oils with fully hydrogenated PIB have very good re-dissolution properties, while dissolution of residues based on partially hydrogenated PIV is no longer possible.
