Abstract
The invention discloses a kind of ageing-resistant rubber sealing ring and preparation method thereof, the rubber seal includes 8 17 parts of 90 120 parts of ethylene propylene diene rubber, 30 50 parts of peroxide diisopropylbenzene (DIPB), 20 30 parts of tannic acid, 10 15 parts of epoxidized soybean oil and carbon black；Its preparation method, which includes to mould in ethylene propylene diene rubber and peroxide diisopropylbenzene (DIPB) input banbury by the parts by weight of constitutive material, practices 3 5min, add tannic acid and mediate 5 7min, discharging, it is cooled to room temperature and puts into mill, add epoxidized soybean oil and carbon black is fully kneaded, elastomeric compound is made, after vulcanizing 100 150s under the conditions of 150 160 DEG C, reprocessing, which is molded, produces the ageing-resistant rubber sealing ring.Advantage is that the ageing-resistant rubber sealing ring has very strong crack resistance, corrosion resistance, sealing and heat-resisting quantity, meanwhile, preparation method materials of the invention are simple, and preparation technology is easy to operate, and it is relatively low to prepare cost.
Description
Technical field
The invention belongs to sealing ring field, more particularly to a kind of ageing-resistant rubber sealing ring and preparation method thereof.
Background technology
The circular cowling that rubber seal is made up of one or several parts, it is fixed on the lasso or packing ring of bearing
On, and with another lasso or washer contacts or forming narrow labyrinth clearance, it is to prevent that lubricating oil from spilling and outside that it, which is acted on,
Thing invades.Rubber seal can be divided into by its material：Silicon rubber series, fluorubber series, polytetrafluoroethylene (PTFE) series, nitrile rubber
Series, chlorobutyronitrile series and ternary ethylene propylene rubber series row.
The content of the invention
Goal of the invention：An object of the present disclosure is to provide a kind of high temperature resistant, ageing-resistant and decay resistance rubber seal
Circle；The second object of the present invention is to provide the preparation method of the rubber seal.
Technical scheme：The ageing-resistant rubber sealing ring of the present invention, in parts by weight including the following raw material：Ethylene propylene diene rubber

, ethylene propylene diene rubber 100-110 parts；Peroxide diisopropylbenzene (DIPB) 35-45 parts；Tannic acid 22-26 parts；Epoxidized soybean oil 12-14 parts.
The method that the present invention prepares ageing-resistant rubber sealing ring, comprises the following steps：By the parts by weight of constitutive material by three
Moulded in first EP rubbers and peroxide diisopropylbenzene (DIPB) input banbury and practice 3-5min, added tannic acid and mediate 5-7min, discharging, cooling
To room temperature and put into mill, add epoxidized soybean oil and carbon black is fully kneaded, elastomeric compound is made, in 150-160 DEG C of condition
After lower vulcanization 100-150s, reprocessing, which is molded, produces the ageing-resistant rubber sealing ring.
Beneficial effect：Compared with prior art, remarkable advantage of the invention is：The ageing-resistant rubber sealing ring has very strong
Crack resistance, corrosion resistance, sealing and heat-resisting quantity, meanwhile, preparation method materials of the invention are simple, preparation technology behaviour
Make simplicity, without the synthesis device of complexity, it is relatively low to prepare cost.
