Abstract
The invention discloses a kind of high oil resistant accumulator capsule glue.This sizing material is with neoprene as main material, the most formulated with adjuvants such as nitrile rubber, soft carbon and sulfuration resistant reducing agents.Make accumulator capsule glue have good oil resistivity by adding nitrile rubber, add sulfuration resistant reducing agent and sizing material can be made to have good heat stability.Compared with prior art, aircraft accumulator capsule glue of the present invention has that hot strength is high, flex fatigue life is good, Heat stability is good and the advantage such as resistance to oil swell is stable.Using the accumulator of this capsule glue, its oil resistant swellability is good, and service life is long.
Description
Technical field
The present invention relates to accumulator capsule glue, be specifically related to high oil resistivity accumulator capsule glue.
Background technology
Accumulator is mounted in a significant components in plane hydraulic system voltage supply oil circuit.Its function is effectively to extend oil
The lotus time of pump and the conversion times of unloader, extend working life, and guarantee that system working pressure is steady, prevent pressure arteries and veins
Dynamic excessive, ensure that each executive component of brake system normally works.Additionally, under the case of emergency such as oil pump fault or conduit failure,
Accumulator can utilize its hydraulic oil stored to brake for locomotive wheel, open and close front deck emergency hatch and the out of order electromotor of manipulation
Carry out spiral feathering and engine cut-off.Therefore, accumulator plays most important effect in plane hydraulic system.If pressure accumulation
Device lost efficacy, and can increase the conversion times of unloader and the working time of oil pump, shorten both working lives, and make in system
Oil temperature significantly improves, and hydraulic pulsation strengthens, and affects each executive component and normally works, the most directly threatens flight safety.But, fly
The most generally there is the problem leaked outside with internal hemorrhage due to trauma in machine accumulator, directly affects the use function of accumulator.Cause this problem
Main cause is that hydraulic oil has swelling and be full of cracks effect to the elastomeric material of accumulator capsule so that it is pressure performance reduces, and
And during using, oil temperature raises, and also can accelerate the aging of material.The elastomeric material research of current domestic resistance to aircraft fluid is also
Immature, the existing resistance to aircraft fluid of accumulator capsule and durability all do not reach the design requirement of type aircraft.Therefore anxious
A kind of elastomeric material with excellent resistance to aircraft fluid need to be developed, to fill up the vacancy of domestic technique, meet the need produced
Want.
Summary of the invention
The invention aims to disclose a kind of high oil resistant accumulator capsule glue, this sizing material has excellent resistance to aviation oil soluble
Swollen property and thermal ageing resistant performance, it is possible to ensure the use safety of capsule and extend its service life.
Height oil resistant accumulator capsule glue of the present invention, is divided two-stage nitration to carry out mixing system by the raw material of following weight parts ratio through banbury
Become:
Neoprene 60 ~ 90
Nitrile rubber 10 ~ 40
Activating agent 4 ~ 10
Age resistor 2 ~ 6
Soft carbon 20 ~ 60
Vulcanizing agent 0.5 ~ 2
Accelerator 0.2 ~ 1
Protection wax 1 ~ 5
Plasticizer 8 ~ 15
Neoprene described in formula is CR322；Nitrile rubber is NBR1704；Activating agent is zinc oxide and magnesium oxide；
Age resistor is age resistor IPPD and anti-aging agent RD, and wherein age resistor IPPD is N-isopropyl-N-diphenyl-para-phenylene diamine；Age resistor
RD is 2,2,4-trimethyl-1,2-dihyaroquinoline polymer；Soft carbon is natural gas semi-reinforcing hydrocarbon black；Vulcanizing agent is sulfur
And stearic acid；Accelerator is Vulcanization accelerator TMTD and altax；Protection wax is Rhein wax；Plasticizer is SA dioctyl ester.
The accumulator capsule glue of the present invention utilizes has high tensile strength, percentage elongation and reversible crystalline neoprene
For material of main part.Meanwhile, for obtaining more preferable oil resistance, and a small amount of nitrile rubber has been used.Old in order to improve the heat of capsule
Change performance, with the use of age resistor IPPD and anti-aging agent RD two class age resistor in formula.
This sizing material is for the test of accumulator capsule, and end properties is good, has passed through oil resistant swell test.Properties of rubber model
Enclose such as table 1 below:
Table 1: properties of rubber
| Project | Performance |
| Conditions of vulcanization | 151 oC×50´ |
| Hardness, Shao Er A type | 65±5 |
| Hot strength, MPa | ≥15 |
| Elongation at break, % | ≥600 |
| Setafter break, % | ≤15 |
| Density, Mg/m3 | 1.32 |
| Volume sweell(ing) rate, % (70oC × 168h, hydraulic engine oil) | ≤15 |
| Elongation change, % (100 is pulled apart after agingoC×48h) | ≥-30 |
It is an advantage of the current invention that: the oil resistance of sizing material and thermal ageing resistant performance are excellent, solve current aircraft pressure accumulation
Device capsule oil resistant swellability is poor, causes the problems such as accumulator gas leak phenomenon, extends the service life of accumulator capsule, ensures and stores
The use safety of depressor.
