Description

A kind of 4 third fluorubber material centralizers and its production technology
Technical field
The present invention relates to centralizer production technology, more particularly to a kind of 4 third fluorubber centralizers and its production technology.
Background technology
The centralizer of underground probe type measuring instrument is used to be sleeved on the external diameter that probe type measuring instrument protects cylinder, helps Positive device must assure that probe type measuring instrument is out-of-date in the mud stream of high temperature, high speed, high pressure, and probe type measuring instrument will not be produced Vibrations and deformation.Existing centralizer is used as main material, resistance to height usually using nitrile rubber, hydrogenated nitrile-butadiene rubber, fluorubber Warm corrosion-resistant, will damage, service life is short, especially for more than 6000 meters within the shorter time of going into the well by erosion Deep mining, downhole temperature is up to 175 DEG C or so, and with high-temperature vapour and oil-based media environment, on this condition, general Elastomeric material is more difficult to meet needs.Below common 130 DEG C of nitrile rubber temperature in use, hydrogenated nitrile-butadiene rubber temperature in use 150 Below DEG C, although fluorubber temperature in use can reach less than 200 DEG C, its poor water resistance, especially water-fast vapor permeability difference, also without Method meets the requirement of application.Therefore, this area need one kind badly can be while meet high temperature resistant, resistance to vapor, resistance to oil machine ambient condition, And reach the stable centralizer elastomeric material used.
The content of the invention
To make up the deficiencies in the prior art, the present invention provides a kind of 4 third fluorubber centralizers and its production technology, and this is helped Positive device can meet 175 DEG C of heatproof, resistance to vapor, the underground work condition for the medium of resistance to oil machine simultaneously.
The present invention is adopted the following technical scheme that:A kind of 4 third fluorubber centralizers, including following parts by weight component:
4 third 100~120 parts of fluorubber, middle 40~55 parts of particle thermal black, Triallyl isocyanurate 3~5 Part, 1~2 part of activating agent calcium stearate, 1~2 part of ternary aliphatic acid, vulcanizing agent two-(t-butylperoxyisopropyl) benzene 1~ 2.5 part.
It is preferred that, the rubber centralizer includes the component of following parts by weight:4 third 100~120 parts of fluorubber, middle grain Sub- 45~50 parts of thermal black, 3~5 parts of Triallyl isocyanurate, 1~2 part of activating agent calcium stearate, ternary aliphatic acid 1~2 part, vulcanizing agent two -1~2.5 part of (t-butylperoxyisopropyl) benzene.
It is furthermore preferred that the rubber centralizer includes the component of following parts by weight:4 third 100 parts of fluorubber, middle particle 50 parts of thermal black, 5 parts of Triallyl isocyanurate, 1 part of activating agent calcium stearate, 1 part of ternary aliphatic acid, vulcanizing agent Two-(t-butylperoxyisopropyl) 1 part of benzene.
The vulcanizing agent be anti-incipient scorch vulcanizing agent, two-(t-butylperoxyisopropyl) benzene, the anti-incipient scorch vulcanizing agent is one Peroxide-based curing dose is planted, coordinates Triallyl isocyanurate and ternary aliphatic acid, optimal incipient scorch state can be reached.
The bonding agent that the present invention is used is phenolic resin binder, and the binding agent only reaches 250 DEG C of decomposition temperature ability Activation point is produced, bridging action is played, makes 4 third fluorubber and metallic framework that there is firm caking property.
It is preferred that, described metallic framework material is without one kind in magnetic cast steel, titanium alloy, brass or red copper.
The cleaning agent that metallic framework cleaning of the present invention is used needs 96 DEG C of 15min bakings for trichloro ethylene after cleaning Brushwork adhesive phenol-formaldehyde A P-5 after dry.
The production technology of above-mentioned centralizer is also claimed in the present invention, specifically includes following steps:
(1) sizing material is prepared, thickness carriage return is standby as requested;
(2) metallic framework trichloro ethylene cleaning by degreasing, sandblasting 10 minutes;
(3) metallic framework after sandblasting in step (2) is used into trichloro ethylene cleaning by degreasing once again;
(4) by the metallic framework after ungrease treatment in baking box 96 DEG C drying 15 minutes after take out;
(5) metallic framework of drying is taken out into brush binding agent AP-5, parks drying in 15 minutes after brushing at room temperature;
(6) metallic framework of binder-treatment is handled 30 minutes for 250 DEG C in baking box;
(7) metallic framework and sizing material are subjected to one step cure processing, 170~185 DEG C of vulcanizations of curing temperature in vulcanizer 20-40 minutes 10 MPas of pressure;
(8) post vulcanization is carried out, 200 DEG C of vulcanizations are raised again to after the vulcanization 1 hour of 190 DEG C of curing temperature and are taken out within 3 hours, are produced Product.
It is preferred that, the one step cure temperature of the rubber centralizer is 170 DEG C, and cure time is 30 minutes.
The present invention, as matrix resin, because its compression set is small, is adapted to pressing from 4 third fluorubber;Four The saturated hydrocarbyl structure of third fluorubber itself so that centralizer can be with resistance to 250 DEG C high temperature, while making the catalysis of high-temperature steam old Change influence and be reduced to minimum, oil-based media is not invaded in centralizer, it is caused to be swelled destruction.Simultaneously based on 4 third fluorine The rock-steady structure of rubber, makes it difficult to bond together with metallic framework, causes product easily to occur rubber and skeleton break-off. The present invention passes through special high temperature bonding technique so that the use time of product is extended twice, and expulsion rate is reduced to original 10%.
The resistance to vapor permeability of product can be improved from calcium stearate, while adding ternary aliphatic acid improves rubber mobility. Because the present invention uses metaideophone technique, require strict, it is necessary to adjust the composition and content of optimum cure agent for curing system, pass through Repetition test matches 5 parts of Triallyl isocyanurate, two-(t-butylperoxyisopropyl) benzene 1 using optimum cure system Part can reach optimal time of scorch.According to optimum cure system, it is decomposition that the present invention, which adjusts out optimum vulcanization process condition, 175 DEG C of temperature, thickness adjustment cure time is 20-40min according to needed for centralizer product.
Compared with prior art, the beneficial effects of the present invention are it is following some:
The present invention is designed by the formula to elastomeric material, by unique process, obtains production available full The stable rubber centralizer used of sufficient long-time, effective storage life is three times of existing centralizer, using specific Binding agent and high-temperature process technique for sticking, it is ensured that rubber situation Nian Jie with skeleton, solve moulding process bonding problem, make rubber Depart from failure conditions with metallic framework and be reduced to original 10%, the centralizer can meet 175 DEG C of heatproof simultaneously, resistance to vapor, The work condition environment of resistance to oil-based media, makes up this area rubber centralizer blank.
