Abstract
The invention discloses a kind of oil well rubber seal and preparation method thereof, the rubber seal includes 8 17 parts of 90 120 parts of nitrile rubber, 30 50 parts of cumyl peroxide, 20 30 parts of nano magnesia, 10 15 parts of fine particle calcium carbonate and cashew nut shell oil；Its preparation method, which includes to mould in nitrile rubber and cumyl peroxide input banbury by the parts by weight of constitutive material, practices 3 5min, add nano magnesia and mediate 5 7min, discharging, it is cooled to room temperature and puts into mill, add fine particle calcium carbonate and cashew nut shell oil 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 oil well rubber seal.Advantage is that the oil well rubber seal 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 without the synthesis device of complexity, it is relatively low to prepare cost.
Description
Technical field
The invention belongs to sealing ring field, more particularly to a kind of oil well rubber seal 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 that a kind of high temperature resistant, oil resistant are resistance to and the oil well rubber of corrosive nature is close
Seal；The second object of the present invention is to provide the preparation method of the rubber seal.
Technical scheme：The oil well rubber seal of the present invention, in parts by weight including the following raw material：Nitrile rubber 90-120
Part, cumyl peroxide 30-50 parts, nano magnesia 20-30 parts, fine particle calcium carbonate 10-15 parts and cashew nut shell oil 8-17 parts.It is preferred that
, nitrile rubber 100-110 parts；Cumyl peroxide 35-45 parts；Nano magnesia 22-26 parts；Fine particle calcium carbonate 12-14 parts.
The method that the present invention prepares oil well rubber seal, comprises the following steps：By the parts by weight of constitutive material by butyronitrile
Moulded in rubber and cumyl peroxide input banbury and practice 3-5min, added nano magnesia and mediate 5-7min, discharging, cooling
To room temperature and put into mill, add fine particle calcium carbonate and cashew nut shell oil is fully kneaded, elastomeric compound is made, under the conditions of 150-160 DEG C
After vulcanizing 100-150s, reprocessing, which is molded, produces the oil well glue sealing ring.
Beneficial effect：Compared with prior art, remarkable advantage of the invention is：The oil well rubber seal has very strong
Crack resistance, corrosion resistance, sealing and heat-resisting quantity, meanwhile, preparation method materials of the invention are simple, preparation technology operation
Simplicity, without the synthesis device of complexity, it is relatively low to prepare cost.
