Description
Technical field
The present invention relates to the oil-in sealing-ring, specifically, is the technology of a kind of automobile braking master cylinder with oil-in sealing ring material and manufacturing sealing-ring thereof.
Background technology
Drift stop is to make the car deceleration in travelling as required or stop in the shortest distance, given play to the device of the performance of running at high speed to make automobile under the premise that security is guaranteed as far as possible, also have and make automobile when descending, keep certain speed of a motor vehicle and guarantee that automobile can rest reliably on the ramp and unlikely smooth effect is therefore closely related with driving safety.Master cylinder has and will convert the hydraulic pressure energy to and then make hydraulic pressure can export to the effect of wheel cylinder by pipeline again from the extraneous mechanical energy of importing, it is the core component that reaches the braking purpose in the drift stop, therefore the oil-in sealing-ring of master cylinder is bearing huge oil pressure, in a single day it defectives such as expanding, dwindle or break occurs, to directly cause brake fade, threaten driver and crew's life security.Yet the master cylinder of present domestic passenger car causes the automobile making cost high with the whole dependence on import of rubber parts, seriously restricted the development of domestic automobile industry, even if the oil-in sealing-ring of import also has the problem of the easy breach of product depanning, performance is very unstable.
Summary of the invention
The object of the present invention is to provide a kind of automobile braking master cylinder oil-in sealing ring material, it has high strength, low compression deformation, can anti tear, the resistance to braking fluid corrosion, and the high and low temperature resistance brilliance, therefore be difficult for breach, stable performance with its oil-in sealing-ring product depanning of making.Another object of the present invention is to provide the technology of making sealing-ring with aforementioned automobile braking master cylinder with the oil-in sealing ring material.
The objective of the invention is to be achieved through the following technical solutions:
A kind of automobile braking master cylinder oil-in sealing ring material is formed by the feed composition proportioning of following weight part: ethylene-propylene rubber(EPR) 80～120, promoting agent 4～6, lubricant 1～3, acid base equilibrium agent 2～4, anti-aging agent 1～3, vulcanizing agent 2～4, mineral filler 25～35;
Described promoting agent is selected import extra light calcined magnesia (Japan's consonance, reactivity coefficient 150) for use;
Described lubricant select for use the import Microcrystalline Wax (U.S. TUV, WB42);
Described acid base equilibrium agent select for use potential of hydrogen less than 8.5 weakly alkaline polyoxyethylene glycol (LG-DOW group, PEG400);
Described anti-aging agent is selected antioxidant NBC (the emerging chemical industry of Japanese imperial palace Co., Ltd.) for use;
Described vulcanizing agent is selected for use efficiently, the tasteless peroxide vulcanizing agent F1440 (Akzo Nobel N.V.) of safety, environmental protection;
Described mineral filler is the low impurity carbon black (U.S. Cabot Co.,Ltd, low impurity carbon black 330R) of import.
Stable performance during import magnesium oxide low temperature is beneficial to sizing material and stores, during high temperature, and superior activity, vulcanization rate is fast, guarantees sulfuration efficient; The Microcrystalline Wax speed of separating out is fast, can form layer protecting film at product surface, has both guaranteed the product stripping performance, also can improve the anti-ozone ability of product; Anti-aging agent adds, and improves the product resistance to elevated temperatures, makes the product resistance to elevated temperatures can reach 180 ℃; The adding of tasteless vulcanizing agent, the place to go smell after the product sulfuration; Low good dispersiveness and the reinforcing effect of impurity carbon black improved product work-ing life greatly.
Further, aforementioned automobile braking master cylinder oil-in sealing ring material, preferably the feed composition proportioning by following weight part forms: ethylene-propylene rubber(EPR) 100, promoting agent 5, lubricant 2, acid base equilibrium agent 3, anti-aging agent 2, vulcanizing agent 3, carbon black 30.
With the technology of aforesaid automobile braking master cylinder, comprise the steps: with oil-in sealing ring material manufacturing sealing-ring
(1) mixing with carrying out after the weight part proportioning of each feed composition by prescription, the compression moulding part;
(2) design combination die, and painstakingly can connect the overlap of thick about 1mm of all products in bottom design, open mould, put into profiled member, once vulcanize typing, curing temperature is 180 ℃～185 ℃, and the time is 270～330s, and pressure is 200～220kgf/cm
2
Can realize multi-cavity depanning simultaneously by pullling overlap when the design of combination die and overlap makes depanning, both shorten the depanning time, guarantee quality product again;
One time sulfidation (is carried out under 270～330s), is torn scarce situation in the time of can preventing the high-temperature product depanning and occur in relatively low temperature (180 ℃～185 ℃) and long time; Sulfuration is at 200～220kgf/cm again
2High pressure under carry out, accelerated the velocity of flow of sizing material, shortened mould-filling time, can prevent that material and current mark from appearring lacking in product;
(3) a sulfurized profiled member cylindrical is carried out die-cut trimming;
(4) put into baking oven, heat up gradually with the heat-up rate of 5 ℃～10 ℃/min and carry out post cure to deepen case depth, curing temperature is 140 ℃～160 ℃, and the time is 2～4 hours;
The mode of Sheng Wening can avoid occurring product because of the shock heating situation that produces breach gradually;
(5) profiled member after the post cure is detected, promptly obtain the automobile braking master cylinder oil-in sealing-ring product of high strength, low compression deformation, anti tear, resistance to braking fluid burn into high and low temperature resistance brilliance after qualified (concrete detection criterion of acceptability is as shown in table 1).
