Definitions
- the invention relates to the field of hydraulic fluids, in particular hydraulic oils for hydrostatic power transmission.
- ester oils of the aforementioned type which are essential for practical use, i.e. H . oils purified based, especially amylopectin and other gums liberated rapeseed oils and / or soybean oils show in practical use, however, two ent ⁇ distinctive weaknesses:
- ester oils based on unsaturated fatty acid systems tend to thicken rapidly even at only moderately elevated operating temperatures of, for example, 50 to 80 ° C. Occasion the willingness of the olefinic double bonds of the ester-forming acids of the oil type concerned here to initiate reactions under the influence of atmospheric oxygen, which ultimately lead to an increase in viscosity. Although it is known in principle that such undesirable increases in viscosity can be dampened by adding antioxidants, especially in hydraulic oils, it has been shown that the antioxidants which have hitherto been used with preference in hydraulic oils based on mineral oil do not perform adequately in ester oils of the type concerned here.
- the object of the invention is to provide effective remedies for the two main sources of error of hydraulic oils described here, based on environmentally friendly base oils.
- the aim of the invention is on the one hand the effective stabilization of such ester oils with substantial proportions of highly unsaturated fatty acid in the ester mixture against oxidative Thickening by adding selected antioxidants, on the other hand, the invention also wants to provide mixture components based on environmentally compatible ester oils, the use of which can substantially reduce the solidification point in the hydraulic oil effectively and over any period of use.
- the invention relates in a first embodiment to an environmentally friendly base oil based on natural substances for the formulation of hydraulic oils with improved viscosity and / or low-temperature stability in use, comprising a) purified rapeseed oil and / or soybean oil as the main oil component, b) 0, 5 up to 5% by weight, based on the total mixture, of anti-oxidants selected from the group:
- these ester oils mixed with the antioxidants selected according to the invention contain, as an additional mixture component c) esters of trimethylolethane, trimethylolpropane and / or neopentylglycol with monocarboxylic acids of the following subclasses cl) saturated C__ 1 n monocarboxylic acids and / or c2) Fatty acids based on rapeseed oil, soybean oil and / or technical oleic acid, the ester components of (c) being at most approximately the same quantity as the main oil component of (a).
- the invention relates to an additive containing antioxidants for stabilizing the viscosity of hydraulic oils based on rapeseed oil and / or soybean oil, which is characterized thereby. that it contains one or more of the following antioxidants Methoxyphenol, ethoxyphenol, butylhydroxyanisole, butylhydroxy toluene, methoxyhydroquinone, ethoxyhydroquinone, tert. -Butylhydroquinone and / or tocopherol.
- these selected antioxidants are present in solution in a preferably high-boiling solvent, which in turn is soluble in the ester oils which form the main oil component and are based on rapeseed oil and / or soybean oil.
- the invention relates to the use of esters of trimethylolethane, trimethylolpropane and / or neopentylglycol saturated with monocarboxylic acids of the following subclasses d).
- monocarboxylic acids and / or c2) fatty acids based on rapeseed oil, soybean oil and / or technical oleic acid for mixing with environmentally friendly hydraulic oils based on rapeseed oil and / or soybean oil, the result being a lowering of the pour point and an improvement in the low-temperature stability of the hydraulic oil can be obtained on an ester basis.
- the mixtures of substances according to the invention differ from the previously known hydraulic oils based on mineral oil, which are widely used in practice, in the selection of the environmentally friendly ester oils of the type mentioned as the basic component of the hydraulic oil.
- the special features of the invention are first of all the first embodiment of the invention described above; H . based on the environmentally friendly base oils based on natural materials for the construction of the hydraulic oils.
- ester oils forming the main oil component are available inexpensively as commercial products.
- Suitable rapeseed oils are in particular the erucic acid-free types that are widespread today.
- Turnip oil in this category usually has a freezing point at -16 C.
- the addition of the selected esters of trimethylolethane, trimethylolpropane and / or neopentylglycol results in a significant reduction in the freezing point or freezing point.
- the ester-forming acids of these mixture components are selected in the two subclasses shown in such a way that they combine the desired viscosity improvement, in particular in the low temperature range, with high environmental compatibility. Accordingly, the use of fatty acids of natural origin in both ester subclasses is preferred in the sense of the inventive action.
- the first ester component based on the trimethylol derivatives mentioned uses, as ester-forming carboxylic acids, comparatively low, in particular saturated, carboxylic acids with a maximum of 10 carbon atoms.
- a known natural starting material of this type are the so-called pre-fatty acids, ie straight-chain saturated monocarboxylic acids with 6 to 10 carbon atoms.
- the esters in this group are distinguished by particularly low solidification values and are therefore particularly suitable. to improve the cold behavior of the main oil components in the desired sense.
- ester-forming carboxylic acids from the second group of the trimethylol derivatives described according to the invention are also suitable for the intended use owing to their structure.
- the reason for this is the high concentration of the olefinically mono- and / or polyunsaturated carboxylic acids of rapeseed oil or soybean oil or technical oleic acid.
- the less represented ester component is present in amounts of at least about 20% by weight, based on this ester mixture to be added to the main oil component.
- the setting point for example of rapeseed oil, is thus lowered in the range from -40 to -45 ° C.
- these main oil components can be added to the main oil component up to: i the amount of approximately equal proportions of the ester mixture to be added - based on the main oil component - without fear of an undesired restriction of the required environmental compatibility .
- the stabilizing agents proposed according to the invention as antioxidants are known compounds from the class of the phenolic inhibitors or corresponding compounds with a hydroquinone basic structure. However, the selection of these stabilizers cannot be taken for granted. It has been shown that by this made according to the invention Selection a surprisingly strong inhibition of the ester oils or ester oil mixtures used according to the invention against the undesirable increase in viscosity due to aging in air can be achieved. The service life and usability of hydraulic oils based on natural materials can thus be extended to a previously unknown extent with largely constant material properties.
- hydraulic oils are not only supposed to have the previously high cold stability, but also a change in the viscosity of the base oil which is as small as possible is required immediately after its production on the one hand or on the other hand after thermal stress in the presence of air.
- the viscosity properties of the hydraulic oils are known to be described in the definition of different viscosity classes according to ISO 3448 or according to DI N 51519. Here means:
- Viscosity (mm 2 / s) at 40 ° C min. Max.
- the viscosity classes ISO-VG 22, ISO-VG 32 and ISO-VG 46 can be set with the substance mixtures according to the invention and maintained over long periods of use.
- the amount of the inhibitor class according to the invention added to the base oil is in the range from 0.5 to 5% by weight, based on the total ester oil mixture. It may be expedient to provide these inhibitors as an additive, dissolved in a solvent.
- Solvents include the solubility of the selected inhibitors over a wide temperature range and the homogeneous miscibility of this solvent in the ester oil mixture. The sufficient low volatility of this solvent is also preferred. Ester oils of various compositions can serve as solvents.
- sulfurized triglycerides sulfurized fatty acid alkyl esters, sulfurized sperm oils
- Phosphoric acid esters such as trioley alcohol phosphate or triaryl phosphate.
- Zinc dialkyldithiophosphate compounds such as zinc (di-2-ethylhexyldithiophosphate) are particularly suitable.
- a mixture of 99% beet oil and 0.33% each of butylated hydroxyl anisole, tert-butylhydroquinone and tocopherol with an initial viscosity of 36 mm / s at 40 ° C was stored in an open vessel at 12 ° C for 12 hours . After this time the mixture had a viscosity of 69 mm / s at 40 ° C.
- the oil is liquid at - 15 ° C.
- the mixture is liquid at - 30 ° C.
- a mixture of 50% beet oil, 25% trimethylolpropane trioleate and 25% trimethylolpropane tricaprylate with an initial viscosity of 33 mm / s at 40 ° C. was stored in an open vessel at 200 ° C. for 110 hours. After this time the mixture had a viscosity of 130 mm / s at 40 ° C. The mixture is liquid at - 30 C.
