Abstract
The invention discloses a kind of valve element fluorubber, using the component of following parts by weight：80-120 parts of rubber, 0.5-1.5 parts of processing aid, 10-15 parts of filler, 3-8 parts of accelerator, 1-5 parts of vulcanizing agent.Compared with prior art, the present invention possesses the characteristics of oil resistant, acid and alkali-resistance, high temperature resistant, low temperature, the encapsulant that can be widely applied under high and low temperature environment.Let out present invention is mainly applied to fluid on the sealed valve core in assembling device, supported the use with fuel tank jettison gear, sealing effectively can be realized to the fluid passage for letting out dress under severe conditions, have good sealing effect, oil resistant, acid and alkali-resistance, in high temperature up to 265 DEG C, low temperature up to long-term use of the advantages of not failing in the environment of 50 DEG C.
Description
Technical field
The invention belongs to rubber, and in particular to a kind of valve element fluorubber.
Background technology
Widely used gear-box speed change in vehicle, ship, engineering equipment, change the weight that machine oil is gear-box maintenance and maintenance
Want content.In order to facilitate machine oil is changed, gear-box uses sets one kind to let out assembling device in oil sump.Assembling device is let out described
Encapsulant requirement possesses the characteristics of oil resistant, acid and alkali-resistance, 265 DEG C of high temperature resistant, low temperature reach -50 DEG C.In the prior art, fluorubber and
Other synthetic rubber can meet oil resistant, acid and alkali-resistance, resistant to elevated temperatures requirement, but it is low temperature resistant be limited in scope, low temperature limit can only achieve-
18 DEG C ~ -23 DEG C, it can not meet -50 DEG C of characteristic requirements.
The content of the invention
The purpose of the present invention is the problem of presence for prior art, there is provided a kind of good sealing effect, hardness is moderate, possesses
The big valve element fluorubber of oil resistant, acid and alkali-resistance, high low temperature resistance range.
To realize that the technical scheme that the object of the invention uses is as follows：
Valve element fluorubber provided by the invention, using the component of following parts by weight：
80-120 parts of rubber, 0.5-1.5 parts of processing aid, 10-15 parts of filler, 3-8 parts of accelerator, vulcanizing agent 1-5
Part.
The component is preferably：
100 parts of rubber, 1 part of processing aid, 13 parts of filler, 6 parts of accelerator, 3 parts of vulcanizing agent.
The rubber is that FKM synthesizes rubber, and processing aid WS280, filler is N990 black smokes, accelerator Ca
(OH)2, vulcanizing agent MgO.
Beneficial effect：
Compared with prior art, the present invention possesses the characteristics of oil resistant, acid and alkali-resistance, high temperature resistant, low temperature, can be widely applied to height
Encapsulant under warm environment.Let out present invention is mainly applied to fluid on the sealed valve core in assembling device, with fuel tank jettison gear
Support the use, under severe conditions can effectively to let out dress fluid passage realize sealing, have good sealing effect, oil resistant,
Acid and alkali-resistance, long-term use of the advantages of not failing in the environment of high temperature reaches -50 DEG C up to 265 DEG C, low temperature.
Technical scheme is further illustrated with reference to embodiment.
Embodiment
Valve element fluorubber of the present invention, using following formula（Parts by weight）：
The FKM synthesis rubber hardness requirement is 70 ± 5 (Shao Er A), and species and grade are GFLT.
Valve element fluorubber is prepared as follows in formula in table：
1st, plasticate：FKM synthesis rubbers cut glue, broken glue into fritter again in 60-70 DEG C of drying rooms after softened by baking, roll spacing 0.3-
0.5mm mill is thin logical 10 times, and bag roller can be kneaded；
2nd, it is kneaded：Roller temperature：40-60 DEG C, it is sequentially added into following components（By weight）：
FKM synthesizes 100 parts of rubber；1 part of processing aid WS280；13 parts of filler N990 black smokes；Accelerant C a (OH)2 6
Part, 3 parts of vulcanizing agent MgO；
After each component adds, it is well mixed, thin it is logical play triangle bag, clot, put down after cut into slices；
3rd, vulcanize：One section 165-170 DEG C, 10min；
Two sections 230 DEG C, 24h（Ensure progressively to heat, to after 230 DEG C, constant temperature clocks）；
4th, calendering formation：Elastomeric compound is pressed into the film of required shape and required size by calender；
5th, injecting glue shaping and vulcanization：Film after calendering is placed in corresponding mould and is molded, 180 DEG C of mold temperature, adds the sulphur time
100s。
As a result each embodiment accords with by heat aging performance test, resistant to liquid test, acid and alkali-resistance test and low temperature resistant test
Close test specification：
