Sealing material poor lubrication, the function of wellhead polish rod are low, cause oil pumping unit seal material serious wear, and oil dripping phenomenon of dripping is tight
Weight, it is therefore necessary to sealed packing is replaced repeatedly, not only increases the labor intensity of worker, causes crude oil to waste, pollution environment, and
And it have impact on the yield of oil pumping.
The content of the invention
It must be replaced repeatedly the invention reside in existing oil pumping unit seal material serious wear present in background technology is overcome
The problem of packing, and a kind of oil well dedicated elas-tic rubber packing is provided.The oil well dedicated elas-tic rubber packing, has higher bullet
Property, abrasion resistance properties are strong, can lift the sealing performance and oil pumping well yield of mouth of pumped oil well polished rod.Present invention also offers one
The preparation method of kind oil well dedicated elas-tic rubber packing.
The present invention solves the problems, such as that it can reach by following technical solution：A kind of oil well dedicated elas-tic rubber packing, its
Component and the parts by weight of each component are：100-200 parts of dimethyl silicone rubber, 30-40 parts of White Carbon black, 40-45 parts of high abrasion carbon black,
20-25 parts of di-iron trioxide, crosslink agent DCP are 3-5 parts, diphenylguanidine PG is 2-4 parts, antioxidant MB is 1-2 parts.
The crosslinking agent is DCP crosslinking agents, and accelerating agent is DPG accelerating agents, and antioxidant is MB antioxidants.
The present invention also provides a kind of preparation method of oil well dedicated elas-tic rubber packing, comprise the following steps：
（1）Dimethyl silicone rubber is weighed up in proportion, is put into rubber mixing machine, the control of rubber mixing machine roller temperature is moulded at 30-50 °C
Refining, time of plasticating at 20-25 minute, when viscosity reaches 10-12, are kneaded uniform, Bao Tongsan times bottom sheet, park 12 it is small when it is stand-by;
（2）The above-mentioned film parked is put into rubber mixing machine again, roller temperature starts to be kneaded between 20-50 °C, treats film bag
After roller, rubber chemicals White Carbon black, high abrasion carbon black, di-iron trioxide, crosslinking agent, accelerating agent, antioxidant are put into proportion, is made
Rubber compound；
（3）By step（2）The rubber compound slice of preparation, weigh, and is put into mould, is then heated on 160 tons of vulcanizers
150-160 °C, pressurization 4kg/cm2 is vulcanized, and vulcanization time determines 20-25 minutes, and product packing is made.
In the oil field oil sludge cleaning agent in each component：Dimethyl silicone rubber has the low temperature resistant superior function of high temperature resistant,
Di-iron trioxide plays the role of increasing weight, and White Carbon black and high abrasion carbon black play the role of reinforcing agent, crosslinking agent and promotion
Agent effect is to promote the vulcanization of rubber, and antioxidant improves the packing service life.
It is of the invention to be had the advantages that compared with above-mentioned background technology：The oil well dedicated elas-tic rubber packing,
Manufacturing process is simple, and material is easy to get, and can all be produced using General Purpose Rubber processing equipment for product, production cost is low.Make
Oil well dedicated elas-tic rubber packing there is higher elasticity, cold-resistant, heat-resisting, oil resistant, acid-alkali-resistant degree and abrasion resistance properties are strong, carry
The sealing performance of mouth of pumped oil well polished rod has been risen, has improved oil pumping well yield.
