Abstract
The invention discloses a kind of oil resisting rubber, by initial rubber conventionally cross-linked rubber production method produce and obtain, it is characterized in that: described initial rubber is made up of following ingredients weight parts: NBR40 butadiene acrylonitrile rubber 85, MPOL200 cis-1,4-polybutadiene rubber 15, zinc oxide 8, stearic acid 1.5, sulphur 0.5, CZ promotor 2.0, TMTD promotor 1.0, channel black 50, DBT dibutyl phthalate (DBP) 5, the rare copolymer resins 15 of vinyl chloride acetic acid second.The tensile tear strength of cross-linked rubber of the present invention is high, and elongation is large, and physical and mechanical properties is stablized, and ensure that the work reliability of rubber core of lubricator, increases the service life.
Description
Technical field
The present invention relates to rubber, be specifically related to the oil resisting rubber of a kind of high strength, high elongation rate and low tension set.
Background technology
Rubber core of lubricator is the core component in well drilling blowout prevention device.Only have the steady quality of glue core reliable, the control effect of guarantee blowout prevention.And the quality of glue core depends primarily on the physical and mechanical properties of cross-linked rubber.Clear and definite property indices in PetroChina Company Limited.'s inner quality standard, the most easily cause glue core to lose efficacy in property indices two large indexs are exactly tensile strength and elongation.With the working condition explanation of the spherical glue core of 35-35, the inside nominal diameter of glue core is ф 350mm, and physical size is ф 360mm, explicitly call for glue core to seal in preventer experiment outline to reach 257 times (qualified) up to standard, glue core can be imagined by ф 360mm hole vanishing under external force squeezing action, the deflection of its rubber and be subject to tractive force and have much.Experiment proves, has many glue cores premature failure in an experiment at present, from reaching about 50% to the probability of tens envelope zero failures several times.The glue core performance of many factories production is now unstable, and quality is unreliable, traces it to its cause:
1. the internal performance of pair initial rubber is not clear, understands ominous especially to the brute force of vulcanized rubber, elongation;
2. pair initial rubber internal performance without clear and definite controlling party to;
3. the technical requirements of pair cross-linked rubber, control method are unclear.
Summary of the invention
The object of the invention is: provide a kind of oil resisting rubber, the tensile tear strength of cross-linked rubber is high, and elongation is large, and physical and mechanical properties is stablized, thus guarantees the work reliability of rubber core of lubricator, increases the service life.
Technical solution of the present invention is: this oil resisting rubber by initial rubber conventionally cross-linked rubber production method produce and obtain, described initial rubber is made up of following ingredients weight parts: NBR40 butadiene acrylonitrile rubber 85, MPOL200 cis-1,4-polybutadiene rubber 15, zinc oxide 8, stearic acid 1.5, sulphur 0.5, CZ promotor 2.0, TMTD promotor 1.0, channel black 50, DBT dibutyl phthalate (DBP) 5, the rare copolymer resins 15 of vinyl chloride acetic acid second.
Wherein, mooney viscosity >=80 of NBR40 butadiene acrylonitrile rubber.
Advantage of the present invention is:
1. select fine 40 sizing materials of fourth of mooney viscosity >=80, ensure that the stable mechanical performance of cross-linked rubber is reliable.
2. adopt butadiene acrylonitrile rubber to be main, the blend compounds that cis-butadiene cement is auxiliary, significantly improve the intensity of cross-linked rubber, elongation and winter hardiness.
3. for ensureing high strength and high drawing, adopting the low sulphur of 0.5 weight part and the low sulfur vulcanization system of 2.0 weight part CZ promotor and 1.0 weight fraction TMTD accelerator combinations, improving cross-linked rubber mechanicalness, ensure stability, the reliability of cross-linked rubber.
Embodiment
Further illustrate technical solution of the present invention below in conjunction with specific embodiment, embodiment can not be interpreted as it is restriction to technical scheme.
Embodiment: by initial rubber conventionally cross-linked rubber production method production oil resisting rubber, described initial rubber is made up of following ingredients weight parts: the NBR40 butadiene acrylonitrile rubber 85 of mooney viscosity >=80, MPOL200 cis-1,4-polybutadiene rubber 15, zinc oxide 8, stearic acid 1.5, sulphur 0.5, CZ promotor 2.0, TMTD promotor 1.0, channel black 50, DBT dibutyl phthalate (DBP) 5, the rare copolymer resins 15 of vinyl chloride acetic acid second.
The tensile strength of the cross-linked rubber of above-described embodiment and elongation are all higher than standard-required.Oil API6A standard-required: tensile strength >=25Mpa, elongation >=350%; The cross-linked rubber of the present embodiment is under 150 ° of C*50min conditions: tensile strength >=29.5Mpa. elongation >=440%, compression set≤11%.
Claims (2)
1. oil resisting rubber, by initial rubber conventionally cross-linked rubber production method produce and obtain, it is characterized in that: described initial rubber is made up of following ingredients weight parts: NBR40 butadiene acrylonitrile rubber 85, MPOL200 cis-1,4-polybutadiene rubber 15, zinc oxide 8, stearic acid 1.5, sulphur 0.5, CZ promotor 2.0, TMTD promotor 1.0, channel black 50, DBT dibutyl phthalate (DBP) 5, the rare copolymer resins 15 of vinyl chloride acetic acid second.
