- C10N2040/08—Hydraulic fluids, e.g. brake-fluids
Definitions
- the present invention refers to liquid compositions that are suited as hydraulic fluids for the transmission of power, particularly as hydraulic break fluids having a content in boron of from 0% to 1% by weight, and consisting of mixtures of glycols, glycolethers of various molecular weights and, possibly, boric glycolesters.
- the breaking systems for motorvehicles represent an important safety element, and the efficient working of the breaks is, to a large extent, determined by the cha racteristics of the hydraulic fluids used in said breaking systems. Therefrom results that on said fluids are imposed by the current regulations very strict requisites, such as concern the prescribed characteristics of: boiling point, viscosity at high and low temperatures, the pH value, the stability at low and high temperatures, re sistance to corresion attack on metals, the swelling action on rubbers.
- par- ticul k rly decisive for the purposes of ascertaining the suitability or unsuitability of a break fluid is theboi ling point at total reflux after humidification (WET PERT) and the viscosity at lew temperatures.
- the affinity fer water not oxly manifests itself in the absorption of water from ahumid gaseous surrounding (atmosphere), but also in determining the intensity of the intramolecular beads which affect the value of the total reflux boiling temperature at atmospheric pressure (PERT) and on the fluidity at lowtem peratures.
- the hydraulic break-fluids normally used must meet all FMVSS 116, DOT-3 and DOT-4 (i.e.:Federal Motor-Vehicle Safety Standard - Department of Transportation) and SAE J 1703 (Society of Automotive Engineers N.Y.) standards.
- the break-fluid belonging to the classes DOT-3 and DOT-4 have the following characteristics:
- French Pat. n°2.158.523 describes liquid compositions for breaks belonging to the class DOT-4, cen sisting of mixtures of tetraethylenglycol, other glycols and lower glycolethers. Said compositions possess a WET PERT slightly greater than 155°C (max. 156.5°C in example n°2), and high viscosity values at low temperatures, due to the presence of tetraethylenglycol (1590 cSt at -40°C in example 1).
- Said liquids named DOT-3 / DOT-4 have been six- gled out in the boric esters of the glycols, and more particularly in the products of the partial or total es terification with boric acid of one or more of the com ponents of the traditional formulations based on alcohols, glycols, glycolethers, polyglycols and polygly- colethers.
- compositions part of the absorbed wateris removed by hydrolysis reactions of the esterwiththe contemporaneous undesired tendency of the boric acid to precipitate.
- organoborates used in the process have the drawback of either causing consistent swellings in the rubbers (esters of etheric glycols) or to produce high viscosities (esters of glycols), and at any ratete cause an unavoidable greater cost in comparison with the traditional formulations.
- object of the present invention is that of providing compositions that be suited for use as hydraulic fluids which, though not containing boron com pounds, possess WET PERT greater than 155°C and viscosities at -40°C that be below 1500 cSt, that is, fluids belonging contemporaneously to the class DOT-3 (with refernce to the viscosity) and to DOT-4 (with reference to the WET PERT).
- Still another object of this invention is that of providing compositions based on boric esters which, at an equal content in boron, will have WET PERT values greater than those of the compositions of the Prior Art.
- a further object of the present invention is that of providing break fluids that will meet all the DOT-3 and DOT-4 specifications; more particularly that will meet the non-agressivity standards towards rubber and the metals present in the breaking system.
- compositions based on the hydraulic fluids of this invention consist of:
- Suitable alkylenglycols consist of: monomethy lenglycol, diethylenglycol, triethylenglycol, monepro- pylenglycol, dipropylenglycol, tripropylenglycol. amongst these, the preferred ones are: diethylenglycol and triethylenglycol.
- Suitable alkylenglycol monoalkylethers(b) consist of: C 1 -C 4 monoalkylethers of alkylenglycols(a). Of these the preferred one is triethylenslycol monoethylether.
- Suitable polyalkylenglycol monoalkylethers (c) are those in which in the above specified general formula:
- Suitable boric esters(d) are the reaction products of a boron compound with alkylenglycols(a).
- the preferred one is the reaction product from the reac tion of boric acid with diethylenglycol.
- the liquid compositions obtained by means of the present invention display all a WET PERT greater than 155°C (lower limit of DOT-4 class), viscosity values at -40°C lower than 1500 cSt (top limit of class DOT-3), and PERT values of about 250°C and over. Moreover, they are characterized by an almost total lack of aggressiveness towards the various types of rubber and metals present in the breaking systems, with a con sequential considerable advantage for the life of said systems; besides displaying all the typical properties of the traditional products of the highest quality.
- compositions of the present invention may be additioned with additives that have the purpose of boosting the performance of the breaking fluids.
- additives that have the purpose of boosting the performance of the breaking fluids.
- various types of additives are com prised: buffering agents, corrosion inhibitors, anti- oxidizers, substances increasing the protective power with respect to ferrous metals in a humid and oxidizing environment, stabilizers, dyestuffs.
- the quantity of additives that may be in corporated into the liquid compositions varies from0% to 10% on the total weight of the compositions.
- the preparation of the boric esters(a) is carried out at atmospheric pressure, preferably in the presence of an azeotropicsolvent, or at a reduced pressure in the absence of a solvent, at temperatures comprised between 50°C and 200°C.
- the formulation of the hydraulic fluids according to the present invention is obtained by mixing together components(a), (b), (c) and (d) and additives in a mixer until achieving a thorough and complete homogenization.
- the mixing is carried out at atmospheric pressure, room temperature and, preferably, in the ab sence of humidity.
