Abstract

An ecological, biodegradable, fluid lubricant and anti-freezing composition for hydraulic systems contains glycol, corrosion inhibitors and antifoaming agents, and must be diluted in water, either before or after it is fed into the hydraulic system, including a shock absorber, preferably in a concentration of 30% to 70% by volume of the composition and of 30% to 70% by volume water.

Description

" ecological, the biodegradable liquid lubricant and the anti-freezing composition that are used for hydraulicefficiency system "
Patent of the present invention relates to a kind of new lubricating fluid compsn that is used to comprise the hydraulicefficiency system of vibroshock; It should dilute in water; Thereby produce a kind of eco-friendly, biodegradable, antifreeze liquid, abide by security and good performance technologies standard and kept all its superperformance to be played the physics and the chemical feature of key effect.
As known technology, the obtainable lubricating fluid (lubricating fluid that wherein is used for vibroshock) that is used for hydraulicefficiency system is formed at it and is contained the mixture of mineral base oil or mineral base oil and as its main ingredient on the market.
Yet the biodegradability of these components is considered to low, promptly " is not easy biodegradable ", therefore must carry out the use of cancellation to this material according to CONAMA resolution 362.
An object of the present invention is to produce a kind of lubricating fluid compsn; It has than the higher biodegradability of obtainable product in the market; And can be used as subsequently and be considered to " being easy to biodegradable " product and be sent to treatment station, be eliminated in another way thus rather than with the above-mentioned mode that it is provided by resolution that.
Another object of the present invention is to obtain a kind of lubricating fluid it can work under minimum temperature (being lower than-45 ℃), and this is to make this product be able to a widely used factor, has avoided laying in the needs of many other products.
In this, according to the present invention, the lubricating fluid compsn of this innovation comprises:
A) more high-load glycol, for example monoethylene glycol; Single Ucar 35; Diethylene Glycol; Dipropylene glycol; With other glycol; This glycol is intended to for lubricating fluid (and product) provides biodegradability, oilness and antifreeze characteristic; Because its biodegradability characteristic, this lubricating fluid can be used as and is considered to " being easy to biodegradable " product and is sent to treatment station and can be widely used and also can under low temperature (even being lower than-45 ℃), work because of it.
B) anti-wear agent of content still less for example contains the bag of organic salt, triazole and surfactant package, Sodium Nitrite, contains the bag of inorganic salt, triazole, sequestrant and tensio-active agent, Sodium Benzoate, borax, amine, acid amides, Hydrocerol A, dodecanedioic acid; This anti-wear agent is intended to avoid because moisture and hydraulicefficiency system wearing and tearing that can take place usually in the system under the operational condition.
C) skimmer, the no silicon combination of hydrocarbon, vegetable fatty acid and glycol; Silicone oil; Simethicone; YSR 3286; The aqueous solution of YSR 3286; This skimmer can be avoided foaming owing to what introducing air in the system in the course of the work caused; Foam can cause lubrication to lose efficacy so should be avoided.
The compsn of this innovation should dilute in water earlier, or in comprising the hydraulicefficiency system of vibroshock, dilutes, the water of the said composition of preferred 30% to 70% volume and 30% to 70% volume.
The theme of patent of the present invention is a kind of " ecological, the biodegradable liquid lubricant and the anti-freezing composition that are used for hydraulicefficiency system ", water soluble, and the form with enriched material comprises:
A) glycol, for example monoethylene glycol; Single Ucar 35; Diethylene Glycol; Dipropylene glycol; With other glycol; Mass ratio is 89.970% to 99.699%, preferred 94.994%;
B) anti-wear agent for example contains the bag of organic salt, triazole and surfactant package, Sodium Nitrite, contains the bag of inorganic salt, triazole, sequestrant and tensio-active agent, Sodium Benzoate, borax, amine, acid amides, Hydrocerol A, dodecanedioic acid; Mass ratio is 0.3% to 10.0%, preferred 5.0%;
C) skimmer does not for example have hydro carbons bag, vegetable fatty acid and the terepthaloyl moietie of silicon; Silicone oil; Simethicone; YSR 3286; The aqueous solution of YSR 3286; Mass ratio is 0.001% to 0.030%, preferred 0.006%.
The lubricating fluid compsn of this innovation can spissated form provide, is used for diluting at water, or diluted, this dilution is preferably carried out with the said composition of 30% to 70% volume and the water of 30% to 70% volume.
The lubricating fluid of this innovation has following work and specification, that is, and and following physics and chemical feature:
Vision clarity aspect; Colourless to light yellow; Motion under 100 ℃ (cinematic) viscosity is that 2 centistokes (cSt) are to 10cSt; Can all be dissolved in the water; Minimum flash-point is 90 ℃; Maximum flow point is negative 45 ℃; And the maximum acidity index is 2mg KOH/g.
