    description
    The invention relates to high temperature oils based on aromatic esters, such as trimellitic esters, pyromelitic acid esters, trimethic acid esters or a floroglucinol mixture or derivatives, such as floroglucinol trioctyl acid ester, tridecyl acid ester floroglucinol and tridodecyl acid ester floroglucinol and a fully hydrogenated or (partially) hydrogenated polyisobutylene, or a mixture thereof.
    High temperature oils, which are used, for example, in the field of industrial lubrication systems on conveyor belts, paint lines, textile industry, insulation materials industry, glass industry, etc., and continuous belt lubrication installations of wood compaction, generally consist of a three-component system.
    This three-component system generally consists of an aromatic ester, a hydrocarbon and a synthetic polymer based on polyisobutylene. Synthetic hydrocarbon is used as a solubilizer. This lubrication system is also added to commercial additives. The disadvantage of these systems is, however, that, with the use of synthetic hydrocarbons, the working temperature of the oil is limited, since they evaporate quickly at temperatures> 200 ° C.
    A three-component system is described, for example, in EP 1 154 011 BI. In this document, a lubricating oil composition is provided which contains an aromatic composition of an ester and as an additional base oil, an α-olefin oligomer, as well as a polyisobutene.
    As mentioned above, the energy loss of a three component lubricant composition, due to evaporation of the solubilizer, is high. Through evaporation, a residue and / or deposit of lubricant components is formed on the application surface or region of use, resulting in the fact that complete lubrication cannot be guaranteed. This deposit must still be removed. In general, the operation of the installation should be suspended and the residue removed. There is, therefore, a need for a high temperature oil, in which the evaporation of the individual components of the oil is greatly reduced even at a constant high temperature, and thus the lubrication effect is not lost for long periods.
    Such high temperature oil is particularly necessary for the lubrication of chains and belts in wooden presses, such as those that are present, for example, in Conti ™ presses for the manufacture of laminate floors.
    The object of the present invention is to provide a high temperature oil in which a good lubricating effect is obtained at constant high temperature for a long period, and which can be supplied in different viscosities depending on the application.
    This goal is surprisingly achieved through the supply of high temperature oil, which as a two-component system comprises an aromatic ester of general formula (I)
    wherein RI is a straight or branched alkyl group having 6 to 16 carbon atoms, and n is 3 or 4, or a composition of general formula (II) wherein R is a straight or branched chain alkyl group having a chain length 8 to 16 carbon atoms and n equals 3, and a hydrogenated polyisobutylene, a fully hydrogenated polyisobutylene or a mixture of a fully hydrogenated polyisobutylene and a hydrogenated polyisobutylene. It preferably comprises a fully hydrogenated polyisobutylene.
    In general, the high temperature oil comprises 40 to 91.9% by weight of aromatic ester of general formula (I) or the composition of general formula (II)
    and 50 to 5% by weight of hydrogenated, fully hydrogenated polyisobutylene or a mixture of hydrogenated polyisobutylene and fully hydrogenated polyisobutylene.
    In addition, the high temperature oil comprises 0.1 to 6% by weight, particularly 2 to 5% by weight of an antioxidant composition.
    In addition, high temperature oil may comprise from 0 to 4% by weight, in particular 0.3 to 3.5% by weight of an anti-wear agent, 0.1 to 1.0% by weight of an inhibitor corrosion, and 0 to 2% by weight, in particular 0.1 to 1.5% by weight of an ionic liquid.
    The ester composition of formula (I) present in the high temperature oil is preferably selected from the group consisting of esters of trimellitic acid, pyromelitic acid, trimethic acid, or mixtures thereof. The composition of general formula (II) is a derivative of floroglucinol (benzene-1,3,5-triol), preferably ester of florocuccinol trioctyl acid, floroglucinol ester of tridecyl acid, ester of tridodecyl acid floroglucinol.
    The antioxidant medium in high temperature oil, which may contain sulfur and / or nitrogen and / or phosphorus present in the molecule, is selected from the group consisting of aromatic amine antioxidants such as alkylated phenyl-alpha-naphthylamine, dialkyl-diphenylamine, sterically blocked phenols, such as butylated hydroxytoluene (BHT), phenolic antioxidants with thioether groups, Zn or Mo or W dialkyldithiophosphates and phosphites.
    The wear protection agent in the high temperature oil is selected from the group consisting of anti-wear additives based on diphenyl cresyl phosphate, amine neutralized phosphates, alkylated and non-alkylated triaryl phosphates, alkylated and non-alkylated triaryl thiophosphates , zinc or Mo or W dialkyldithiophosphate, carbamates, thiocarbamates, zinc or Mo or W dithiocarbamates, dimercaptotiadiazole, calcium sulfonates and benzotazole derivatives.
    The corrosion inhibitor in high temperature oil is selected from the group consisting of additives based on "overbasified" calcium sulfonates containing a TBN of 100 to 300 mg KOH / g, calcium phosphates neutralized with amine, naphthalenesulfonates of alkylated calcium, oxazoline derivatives, imidazole derivatives, succinic acid hemi-ester, N-alkylated benzotriazoles.
    The ionic liquid (IL) used in high temperature oil is the well-known molten salts which, by definition, are liquids at temperatures below 100 ° C. Many ionic liquids are liquids at room temperature or at lower temperatures. Suitable cations for ionic liquids are quaternary ammonium cation, phosphonium cation, an imidazolium cation, a pyridinium, pyrazolium, oxazolium cation, a pyrrolidinium cation, a guanidine cation, or a morpholine cation or a triazole cation, with an anion selected from the group consisting of [PF6] “, [BF4]“, [CF3CO2] ', [CF3SO3]', [(CF3SO2) 2N] ', [(R4S02) (R5S02) N] ', [(CF3SO2) (CF3COO) N] _, [R4-SO3]', [R4 -0-S03] ', [R4-COO] “, cr, Br', [NO3] ', [N (CN) 2] ', [HSO4]', OU [R4R5PO4] ', and the radicals R4 and R "are independently selected from hydrogen; alkyl groups with 1 to 20 linear or branched, saturated or unsaturated carbon atoms, aliphatic or alicyclic, heteroaryl alkyl groups, C4-CÓ heteroaryl with 3 to 8 carbon atoms in the heteroaryl radical, and at least one N, O and S heteroatom, which can be substituted with at least one group selected from the alkyl groups C2-C6 and / or halogen atoms; s aryl-aryl-C 1 -C 6 alkyl having 5 to 12 carbon atoms in the aryl radical, which can be substituted with at least one C 1 -C 3 alkyl group, can be combined, partly or fully fluorinated alkyl radicals. However, other combinations are also possible. Anions of the type [PF! 6_x) R7X] ’, [R'SO3]’ are also known. R7 here represents partially or fully fluorinated radicals such as pentafluoroethyl or perfluorobutyl. Also very thermally stable is the anion type (FS02) 2N “.
    In order to have a positive effect on oils, ionic liquids must first have an oil solubility, however, complete miscibility is not absolutely necessary. Ionic liquids must be thermally stable and do not promote corrosion, for example, in the presence of water do not form very corrosive reaction products, or form them only very slowly.
    Particularly advantageous are ionic liquids, such as tetraalkylammonium- and tetraalkylphosphonium bis (trifluoromethyl-sulfonyl) imides, such as, for example, trihexyl (tetradecyl) phosphonium-bis (trifluromethylsulfonyl) imide and (HPDimide) and methyl-trifluoride (methyl-trifluidyl) amide (Moimid). Also particularly advantageous are ionic liquids, such as tetra alkyl ammonium- and tetra alkyl tris (perfluoroethyl) trifluoro phosphate such as, for example, tetrabutylphosphonium tris (perfluoroethyl) trifluoro phosphate (BuPPFET), trihexyl (tetradifluoro) -tris (perfetoro) fluoro phosphate (HDPPFET). Pyrrolidine tris (perfluoroethyl) - trifluorphosphate has also proved particularly advantageous. Also particularly advantageous were tetralkylammonium and tetraalkylphosphonium perfluorbutansulfonates, such as trihexyl (tetradecyl) phosphonium (HDPnonaflat) perfluorobutanesulfonate.
    Any mixtures of ionic liquids can also be used.
    The two-component system of the present invention performs substantially better in terms of thermal stability and residue formation or residue behavior. The enormous increase in thermal stability is of particular benefit for a significant increase in lubricating behavior. Lubrication intervals have been extended and energy savings of up to 30% in electrical energy can be achieved.
    As mentioned above, the formation of waste is significantly reduced. Thus, the formation of residue cracking is reduced and the residue formed can be removed very easily with the new oil.

The mixture is stirred for 1 hour to obtain a homogeneous mixture. The anti-wear agent and the antioxidant are added at 60 ° C with stirring. After about 1 hour, the finished oil can be filled into the containers provided. Comparative Example 1

    High temperature oil composition: 47.4% by weight of aromatic trimellitic acid ester 16.0% by weight of polyisobutylene 30.0% by weight of synthetic hydrocarbon 3.5% by weight of anti-wear agent 3.0% by weight antioxidant weight 0.1% by weight of corrosion inhibitors
    As an aromatic ester, a trimellitic acid ester is placed together with the poly-a-olefin as a synthetic hydrocarbon in a stirring tank. At a temperature of 100 ° C, the polyisobutylene is added with stirring. The mixture is stirred for 1 hour to obtain a homogeneous mixture. Anti-wear and antioxidant agents are added with stirring at 60 ° C in the tank. After about 1 hour, the finished oil can be filled into the containers provided.
    The advantages of the high temperature oil of the invention will be shown below.
    The basic oil data for Example 1 and Comparative Example 1 are shown in Table 1. Table 1
    1.1. Thermal stability studies
    Investigations were carried out on evaporation and viscosity under temperature load, on 5 g of sample weight in an aluminum dish at 230 ° C. For this, the oils are compared with each other according to Example 1 and Comparative Example 1. Table 2

    The above results show that, by using fully hydrogenated polyisobutylene in a two-component high-temperature oil, the increase in viscosity and evaporation loss compared to the known three-component oil can be significantly reduced. These results are represented graphically in Figures 2 and 3. 1.2. Comparison of friction values
    The oils prepared in Example 1 and Comparative Example 1 were used to determine the friction coefficients. A translational oscillation test (SRV) was carried out in accordance with DIN 51834, ball / disc test condition, 250 N load, 50 ° C to 250 ° C, 1 mm 50 Hz stroke, 165 min. The results are shown in Table 3. Table 3

    These results, which are also shown in Figure 1, show the positive effect of high temperature oil based on two components on the friction coefficient, compared to the three component system. 1.3. Residue behavior after complete evaporation of the oil at 250 ° C.
    The formation of residues and the behavior of residues in relation to solubility were studied.
    The oil to be tested is weighed with a steel plate previously folded and cleaned with a solvent with 5 g and then evaporated at 250 ° C in a drying cabinet with air circulation for at least 72 hours. The square sheet is folded by hand on all four sides, to result in a bowl shape. After cooling, the results of the new weighing are noted. Essential for this test is to determine the partial solubility of the residue in new oil and the amount of residue formed. For this purpose, a drop of fresh oil is applied to the residue and rubbed with a slightly rounded glass rod in a circular motion.
    The results show that the high temperature oil according to the invention with 4.8% forms less waste than the known oil, which has a 6.0% deposit. The residue formed by the high temperature oil of the invention is very dissolvable, which means that these residues are easy to remove with new oil. In contrast, the known oil residue can be significantly more difficult to remove with new oil. 1.4. Performance chain testing
    Figure 12 shows a performance chain test bench operating under the following test conditions Temperature: 220 ° C Speed: 2 m / s, Load: 2600 N Elapsed time after 0.1% chain elongation, 22 hours on Example 1 and 17 hours in Comparative Example 1
    Before testing, the chain is dipped in the oil to be tested. Once dipped, the chain is hung so that excess lubricating oil can drain. Finally, the chain is placed on the performance test bench (see Figure 10) and the test begins under the specified conditions. It is possible to vary the temperature, speed and load. θ execution time is defined with a 0.1% chain lengthening. Chain elongation is caused by wear on the chain links during the test run. Example 2

In contrast, the known oil residue can be significantly worse than removing it with new oil. 3.4. Performance chain testing
    The chain performance test was carried out at 220 C, at a speed of 2.0 m / s and a load of 2600 N. The duration after stretching 0.1% of the chain is 17 h for Example 3 θ a of Comparative Example 3 is 15h. The test was carried out as described in Example 1. Example 4

    Even with high temperature oil based on a floroglucinol derivative, the results described above in detail could be obtained.
    The above experimental results show that, by the high temperature oil according to the invention, significantly better results were obtained for all tests performed than those with the known high temperature oils.
    In summary, it can be established that the two-component system of the present invention performs significantly better in terms of thermal stability and residue formation or waste behavior. The enormous increase in thermal stability is of particular benefit in a significant increase in lubricating behavior. Lubrication intervals have been extended and energy savings of up to 30% in electrical energy can be achieved.
