More specifically, the sterically hindered ester has a higher fire point (Fp) than the poly(alkylene glycol), which typically sufficiently lowers the S.F.P. of the fluid composition to allow the fluid composition to rate as a Factory Mutual Approved Fluid.

Description

The fluid composition that has excellent fire-resistance
Technical field
[0001] the present invention relates generally to be used for the fluid composition of industrial fluids purposes.More specifically, the present invention relates to wherein require the fluid composition as hydraulic pressure, compressor, gear, bearing or turbine fluid compositions of excellent fire resistance.
Background technology
[0002] at many industrial sectors, used fluid composition ignites and abnormally dangerous with the fire that afterfire caused in the industry.This takes place under the occasion of the high enough temp that fluid composition stands to exist so that this fluid composition that ignites usually.
[0003] fire-resistant fluid compositions be applied to this fluid composition and high temperature surface or other ignition source closely near and therefore jeopardize in the industry of people's life.These special fluids also can't be implemented or combine with the mechanical firefighting system when being used for more fully protecting in the mechanical firefighting measure and use.In the general industry that has fire hazard is used, use fire-resistant fluid compositions normally to make industrial equipments obtain insuring necessary to a certain extent.
[0004] requiring the main kind of the fluid composition of excellent in resistance bad temper is composition of hydraulic fluid, this is because these fluid compositions are under the pressure in hydraulic efficiency system and when firing the source with potential contact point in the atomized spray, this atomized spray form is high flammable liquid form.Fire-resistant fluid compositions also is used for other kind fluid composition, comprises gear, compressor and turbine fluid compositions.
[0005] the common base-material that is used for fire-resistant fluid compositions comprises ester, poly-(aklylene glycol), vegetables oil, and phosphoric acid ester.The fluid composition that comprises poly-(aklylene glycol) has special purposes in the lubrication applications of compressor, gear, bearing, hydraulic pressure and turbine system.This fluid composition is usually included in the fluid composition poly-(aklylene glycol) more than 85 weight parts, based on the gross weight of fluid composition.Ester is another kind of composition, becomes known in the lubrication applications of compressor, pump and hydraulic machinery.This ester has been used as the surrogate of the fluid composition that comprises poly-(aklylene glycol).
[0006] comprises that several industries of the Factory Mutual ResearchCorporation (FMRC) that is called FM Global have now set up the standard of the composition of hydraulic fluid resistivity against fire of oneself.FM Global identifies the fluidic resistivity against fire according to the standard C N 6930 of their approval, accepts extensively the authentication of FM Global in industrial circle.For example, the sale that has industrial plants of potential fire hazard to U.S.'s great majority requires the resistivity against fire composition of hydraulic fluid authentication of FM Global usually.If can use, using the resistivity against fire composition of hydraulic fluid of FM Global approval generally is to make this equipment obtain insuring necessary.
[0007] standard of FM Global authentication resistivity against fire composition of hydraulic fluid changed in recent years.FMRC requires composition of hydraulic fluid by spray flammability test and hot tube ignition (hot channel ignition) at first in their standard C N 6930-1975.The standard C N 6930-1975 that admits of FM Global according to revision, the makers-up of ester-based composition and use thereof in packaging determines to add the viscosity adjustment additive in ester-based formulas makes this fluid composition can meet CN 6930 standards, and will not meet standard with the same recipe of viscosity modifier.Yet, the improvement of the resistivity against fire that causes because of the viscosity adjustment additive is attached this viscosity adjustment additive that keeps higher molecular weight, it can not keep the long period in industrial application, because this viscosity modifier is responsive especially to the mechanical shearing of fluid composition under normal service condition.The U.S. Pat 5,141,663 of the Miller use anti-fog additive of having demonstrated makes poly-(aklylene glycol)-based composition and use thereof in packaging obtain the described authentication of FM Global according to CN 69230.Anti-fog additive is a high-molecular weight compounds as viscosity index modifiers, and it increases fluid composition under the condition of CN 6930-1975 standard drop size makes fluid pass through check and access authentication.
[0008] at FM Global in 2002 revised CN 6930 standards are disclosed, its replace old standard and redefining be intended to be used for such as but be not limited to the prerequisite of lubricant, hydrostatic transmission, the control of steam turbine speed control device, transformer insulated and refrigerative industrial fluids flammability classification evaluation.This revised standard convection cell fire resistance grading is by their spray flammability parameter (S.F.P.) numerical value.S.F.P. be by estimating the calculated value that this fluid flammability characteristics obtains.S.F.P. calculate according to following formula (1):
Q wherein ChBe the chemical heat rate of release,
p fBe fluid composition density,
q CrBe the critical heat flux that is used to ignite, and
m fIt is the mass rate during measuring this chemical heat rate of release.
[0009] use the Factory Mutual 10 that is positioned at FM Global, 000kW-level products of combustion collector (Fire Products Collector) is by measuring the chemical heat rate of release (Q that the fluid composition mist sprays Ch) acquisition S.F.P..Use burning-point numerical value to obtain to be used for the critical heat flux (q of fluid composition igniting by following equation 2 via the burning-point of measuring fluid composition Cr):
q cr = α × σ × T f 4 - - - ( 2 )
Q wherein CrWith above-mentioned,
α is the uptake factor (being assumed to 1) of fluid composition,
σ is Si Tefen-Boltzmann constant (5.67 * 10 -11KW/m 2K 4), and
T fIt is the burning-point (° K) of fluid composition.
[0010] this spray flammability parameter (spray flammabilityparameter) (S.F.P.) can be according to stipulating in FM Global Recognized Standards; CN6930 (in January, 2002 revision), by using following formula 3 estimations:
Figure A20078004926700072
S.F.P. wherein, p fAnd T fWith above-mentioned, and
Δ H TIt is net heat of combustion.
The S.F.P. numerical value of the fluid composition of [0011] use mensuration, FM Global is categorized as 0 class, 1 class and 2 classes with fluid, and 0 class resistivity against fire is the strongest and 2 class resistivity against fires are the poorest.The concrete standard in January, 2002 illustrates in greater detail in following table 1.
Table 1
Resistivity against fire fluid classification (FMG standard C N6930, in January, 2002) Stdn S.F.P. Note
0 class Not flammable Fluid satisfies 1 generic request based on S.F.P., and qualified 0 class that is assessed as is not flammable, and condition is to experimental results show that through ASTM D240-92 the perfect combustion net heat is 4kJ/g or lower when it
1 class 5×10 4Or it is lower Generally can not the stabilization jet flames
2 classes 5×10 4-10×10 4 Greater than 10 * 10 4S.F.P. do not approved
[0012] it is approximate to immediate integer to be used to measure the calculating of S.F.P..For example, 5.8 * 10 4S.F.P. upwards approximate and be reported as 6 * 10 45.5 * 10 4S.F.P. approximate downwards and be reported as 5 * 10 4
The new CN6930 standard reversal in [0013] 2002 year obtain the mode of above-mentioned CN6930-1975 standard approval with antifog and viscosity modifier additive.Because their high carbon contents and low ignition point, many poly-(aklylene glycols) of previous CN6930-1975 standard approval and ester-based composition and use thereof in packaging can only obtain the grading of 2 classes according to CN6930 standard in 2000.Though the density of fluid composition remains factor, two key characteristics of S.F.P. are mainly from chemical heat rate of release (Q Ch) and this critical heat flux (q Cr), as above-mentioned.Chemical heat rate of release (Q Ch) based on the fluid carbon content thereby be difficult to change, and critical heat flux (q Cr) directly relate to the burning-point (T of fluid composition f) and can change.
[0014] as mentioned above, become advantageously by add other component to this fluid composition to improve burning-point (T f), cause critical heat flux (q CrThereby) increase and reduce the S.F.P. that S.F.P. reduces the fluid composition that comprises poly-(aklylene glycol).For example, people's such as Totten PCT application W001/90232 discloses poly-to comprising (aklylene glycol) and has added antioxidant to reduce S.F.P. in fluid composition.Poly-(aklylene glycol) thermo-oxidative stability known in this field is very limited and require antioxidant for all high performance fluids compositions based on poly-(aklylene glycol), no matter whether this fluid composition will be used for the important occasion of resistivity against fire.Although antioxidant can reduce poly-(aklylene glycol) S.F.P. to a certain position, but must be noted that the employed equatioies of S.F.P. for obtaining to report such as Totten, and the S.F.P. scope that is used to classify is changed by FM Global, thereby in all embodiment that Totten etc. provides except one, all burning-points of report all cause fire resistance rating than Totten etc. claim poor.
[0015] in May, 2004 FM Global two classes are changed in the S.F.P. classification of standard C N 6930; " FM approval ", it is more fire-resistant, and " concrete test ", and it is more not fire-resistant.In following table 2, illustrate in greater detail new classification.
Table 2
Resistivity against fire fluid classification (FMG standard C N6930, in May, 2004) Stdn S.F.P. Note
The fluid of FM approval 5 * 10 4Perhaps lower Generally can not the stabilization jet flames
The fluid of concrete test 5 * 10 4-10 * 10 4 Greater than 10 * 10 4S.F.P. do not approved.Whether the fluid of concrete test will specifically be planned at each by the FM field engineer or current application is checked with decision except that the fluid of this concrete test need mechanical firefighting to equip so that acceptable fire rating to be provided.
[0016] limited application will gather (aklylene glycol) and sterically hindered ester is combined in the same fluid composition.More particularly, sterically hindered ester has been used to gather (aklylene glycol)-Ji compressor oil as sludge-dispersant.For example, the U.S. Pat 4,302,343 of Carswell etc. discloses compressor lubricant, and it comprises 15-45 weight part be obstructed ester and 55-85 weight part poly-(aklylene glycol).This ester has sufficient high-temperature stability to suppress the time limit of service that sludge formed thereby prolonged compressor oil.Yet, ester is subject to the hydrolytic instability influence, and the ester of the quantity of statement such as Carswell is present in and can causes blend viscosity to increase in the compressor fluid, needs thus to use than low viscosity poly-(aklylene glycol) so that this fluid composition keeps the identical viscosities grade.Than low viscosity and thus lower molecular weight poly-(aklylene glycol) will have than low ignition point, offset thus by comprising any improvement of the burning-point aspect that ester obtains.Therefore, above-mentioned high-load ester does not meet the requirement of many application in the fluid composition, especially payes attention to the application scenario of stability to hydrolysis and fluid viscosity.
[0017] because the deficiencies in the prior art, the fluid composition that has more than 85 weight parts poly-(aklylene glycol) need be provided, it be formulated as reduce fluid composition S.F.P. to having under the above-mentioned high-content poly-(aklylene glycol) even adding the level that does not also reach under the antioxidant up to now.
Summary of the invention and advantage
[0018] the invention provides fluid composition, this fluid composition comprises: have poly-(aklylene glycol) of quantity more than 85 weight parts, based on described fluid composition gross weight, and to have quantity be from the 0.5 sterically hindered ester until 15 weight parts, based on described fluid composition gross weight.
[0019] quantity that exists of this sterically hindered ester is until 15 weight parts from 0.5, based on the fluid composition gross weight,, this fluid composition do not have influence in fact for other physicals fluid composition such as viscosity and the stability to hydrolysis for providing good fire resistance.More particularly, this sterically hindered ester is than should poly-(aklylene glycol) having higher burning-point (F p) and for this fluid composition provides good fire resistance, it allows this fluid composition to be assessed as the fluid of Factory Mutual approval under current standards.
