Abstract
The invention discloses high oil-resistant accumulator capsule gel, which is prepared from chloroprene rubber as a main raw material, and nitrile rubber, soft carbon black, an anti-sulfur reducing agent and the like as auxiliary materials according to a certain ratio. Due to addition of the nitrile rubber, the accumulator capsule gel has good oil resistivity; and due to addition of the anti-sulfur reducing agent, the gel has good thermal stability. Compared with the prior art, the accumulator capsule gel for an airplane has the advantages of high tensile strength, good anti-flex cracking property, good thermal stability, stable oil swelling resistance and the like; and the accumulator using the capsule gel is good in oil swelling resistance and long in service life.
Description
Technical field
The present invention relates to pressure accumulator capsule glue, be specifically related to high oil-proofness pressure accumulator capsule glue.
Background technology
Pressure accumulator is mounted in a significant components in plane hydraulic system voltage supply oil circuit.Its function effectively extends the unloading time of oil pump and the conversion times of unloading valve, extends working life, and guarantee that system working pressure is steady, prevents pressure pulsation excessive, ensures that each power element of brake system normally works.In addition, under the emergency situation such as oil pump fault or conduit failure, the hydraulic efficiency oil that pressure accumulator can utilize it to store is for locomotive wheel brake, and open and close front deck emergency exit and the out of order engine of manipulation carry out spiral feathering and engine stopping.Therefore, pressure accumulator plays most important effect in plane hydraulic system.If pressure accumulator lost efficacy, can increase the conversion times of unloading valve and the working hour of oil pump, the working life of both shortenings, and the oil temperature in system is significantly improved, hydraulic pulsation strengthens, and affects each power element and normally works, even directly threaten flight safety.But aircraft pressure accumulator but ubiquity leaks outside and the problem of interior leakage, directly affects the using function of pressure accumulator.Cause the major cause of this problem to be that the elastomeric material of hydraulic efficiency oil to pressure accumulator capsule has swelling and be full of cracks effect, its withstand voltage properties is reduced, and in use procedure, oil temperature raises, and also can accelerate the aging of material.The elastomeric material research of current domestic resistance to aeronautic hydraulic oil is also immature, and the resistance to aeronautic hydraulic oil of existing pressure accumulator capsule and weather resistance all do not reach the design requirements of type aircraft.Therefore be badly in need of developing a kind of elastomeric material with excellent resistance to aeronautic hydraulic oil, to fill up the vacancy of domestic technique, meet the needs of production.
Summary of the invention
The object of the invention is to disclose a kind of high oil resistant pressure accumulator capsule glue, this sizing material has excellent resistance to aviation oil swell and thermal ageing resistant performance, can ensure the use safety of capsule and extend its work-ing life.
Height oil resistant pressure accumulator capsule glue of the present invention, divides two sections to carry out mixing making by the raw material of following weight parts ratio through Banbury mixer:
Chloroprene rubber 60 ~ 90
Paracril 10 ~ 40
Promoting agent 4 ~ 10
Anti-aging agent 2 ~ 6
Soft carbon 20 ~ 60
Vulcanizing agent 0.5 ~ 2
Promotor 0.2 ~ 1
Protection wax 1 ~ 5
Softening agent 8 ~ 15
Chloroprene rubber described in formula is CR322; Paracril is NBR1704; Promoting agent is zinc oxide and magnesium oxide; Anti-aging agent is anti-aging agent IPPD and anti-aging agent RD, and wherein anti-aging agent IPPD is N-sec.-propyl-N '-diphenyl-para-phenylene diamine; Anti-aging agent RD is 2,2,4-trimethylammonium-1,2-dihyaroquinoline polymer; Soft carbon is Sweet natural gas semi-reinforcing hydrocarbon black; Vulcanizing agent is sulphur and stearic acid; Promotor is Vulcanization accelerator TMTD and altax; Protection wax is Lay mattress wax; Softening agent is SA dioctyl ester.
It is material of main part that pressure accumulator capsule glue utilization of the present invention has compared with high tensile, elongation and reversible crystalline chloroprene rubber.Meanwhile, for obtaining better oil resistance, and use a small amount of paracril.In order to improve the heat aging performance of capsule, with the use of anti-aging agent IPPD and anti-aging agent RD two class anti-aging agent in formula.
This sizing material is used for the test of pressure accumulator capsule, and end properties is good, have passed oil resistant swell test.Properties of rubber scope is as following table 1:
Table 1: properties of rubber
| Project | Performance |
| Cure conditions | 151 oC×50′ |
| Hardness, Shao Er A type | 65±5 |
| Tensile strength, MPa | ≥ 15 |
| Tensile yield, % | ≥ 600 |
| Setafter break, % | ≤ 15 |
| Density, Mg/m 3 | 1.32 |
| Volume swelling rate, % (70 oC × 168h, hydraulic engine oil) | ≤ 15 |
| Elongation change is pulled apart, % (100 after aging oC×48h) | ≥-30 |
The invention has the advantages that: the oil resistance of sizing material and thermal ageing resistant performance excellence, solve current aircraft pressure accumulator capsule oil resistant swelling property poor, cause the problems such as pressure accumulator gas leak phenomenon, extend the work-ing life of pressure accumulator capsule, ensure the use safety of pressure accumulator.
