Abstract
The present invention relates to a kind of oil pumping cabinet carbon silicone oil envelopes.Mainly solve the problems, such as that existing oil pumping in oil fields cabinet carbon silicone oil envelope service life short oil resistant rub proofness is poor.It is characterized by: its component of the oil sealing and proportion are as follows by weight percentage: carbon 10-20%, silica gel 30-40%, expanded graphite 20-30%, nitrile rubber 20-30%；Preparation method includes the following steps: film being put into mold at film and be heated to 120-150 DEG C of sulfidization molding by vulcanizing press carbon, silica gel, expanded graphite, the refining of nitrile rubber epoxy glue in proportion.Oil pumping cabinet carbon silicone oil envelope, oil resistant rub proofness is high, long service life, and high-low temperature resistant degree is good.
Description
Technical field
The present invention relates to a kind of oil sealing in oil-field oil pumper field, especially a kind of oil pumping cabinet carbon silicone oil envelope.
Background technique
Currently, be largely reclaimed rubber, small part in the oil pumping cabinet oil sealing material that existing oil-field oil pumper uses being fourth
Fine rubber, therefore the manufactured oil sealing service life is short, replaces once a week；Oil resistant, rub proofness are excessively poor；High- and low-temperature resistance degree is very
Difference, under normal circumstances, high-low temperature resistant are 0 degree or less and 20 degree or more, do not have sealing function, outward permeability, it has to replace
New oil sealing is frequently replaced, influences normally to produce, and discarded oil sealing is thrown into well site pollution environment.
Summary of the invention
The invention reside in overcome existing oil pumping in oil fields cabinet oil sealing service life short oil resistant rub proofness present in background technique
The problem of difference, and a kind of oil pumping cabinet carbon silicone oil envelope is provided.Oil pumping cabinet carbon silicone oil envelope, oil resistant rub proofness is high, uses the longevity
Life length, high-low temperature resistant degree are good.The present invention also provides a kind of preparation methods of oil pumping cabinet carbon silicone oil envelope.
The present invention solves the problems, such as that it can reach by following technical solution: a kind of oil pumping cabinet carbon silicone oil envelope, the oil
Envelope is prepared by the component of following parts by weight: carbon 10-20%, silica gel 30-40%, expanded graphite 20-30%, nitrile rubber
20-30%。
The present invention also provides it is a kind of oil pumping cabinet carbon silicone oil envelope preparation method, comprising the following steps: in proportion by carbon,
Film is put into mold and is heated to by vulcanizing press at film by silica gel, expanded graphite, the refining of nitrile rubber epoxy glue
120-150 DEG C of sulfidization molding.
In oil pumping cabinet carbon silicone oil envelope in each component: the carbon have 35-50 DEG C of high temperature resistant, it is 35-50 DEG C low temperature resistant,
Wear-resisting property is 0.04%(24 hours) it does not tear, indeformable performance；Silica gel not only has high-low temperature resistant, anticorrosive, acidproof
Alkali, crocking resistance are fabulous, wear resistance 5-12Mpa；Expanded graphite has high-low temperature resistant, wear-resisting property, automatic swollen after viscous oil
Swollen, sealing function is splendid；Nitrile rubber is with oil resistivity (especially alkane oil) is good, wearability is high, air-tightness is good, heat resistance
Well, the advantages that bonding force is strong, ageing-resistant performance is preferable.
The present invention can have the following beneficial effects: that the oil pumping cabinet carbon silicone oil seals compared with above-mentioned background technique, not dirty
Contaminate environment；Service life improves 3-5 times of the service life compared with conventional material；It is indeformable between 35-50 DEG C of high-low temperature resistant, sealing is kept,
It is non-leakage；It is antiacid alkali, corrosion-resistant.
Specific embodiment:
Below in conjunction with specific embodiment, the invention will be further described:

Embodiment 3
13 g of carbon, silica gel 32g, expanded graphite 26g, the refining of nitrile rubber 20g epoxy glue are put film at film in proportion
Enter in mold and 120-150 DEG C of sulfidization molding is heated to by vulcanizing press.
Comparative example 4
Film is put into mold at film by reclaimed rubber 50g, natural rubber 25g, the refining of nitrile rubber 25g epoxy glue in proportion
It is interior that 120-150 DEG C of sulfidization molding is heated to by vulcanizing press.
Embodiment 1 to 3, the preparation oil pumping cabinet carbon silicone oil envelope of comparative example 4, the measurement result of each index is measured are as follows: implement
Example 1 to 3 is pumped cabinet carbon silicone oil envelope service life 3-6 months；It is indeformable between 35-50 DEG C of high-low temperature resistant, sealing is kept, it is not permeable
Leakage；It is antiacid alkali, corrosion-resistant；The oil pumping cabinet carbon silicone oil envelope service life of comparative example 4 only has 10 days；High low temperature resistance range ± 10-15
℃.Medicament used in embodiment is commercially available.
