Problems solved by technology

[0002] With the continuous update of the operating environment of oil drilling platforms, the composition of drilling oil-based mud with oil as the dispersion medium has also changed. The standard NEK606 for mud-resistant cables and oil drilling platforms was upgraded in 2016. The drilling fluid was changed from the original fluid CarboSea Calcium bromide oil-based mud was changed to EDC-95-11. This oil-based drilling fluid is severely corrosive to the cable sheath and greatly reduces the service life of the cable. In the past, ethylene vinyl acetate EVA and ethylene butyl acrylate EBA were used The sheath is difficult to meet the requirements

Embodiment 1

[0021] The mud resistant SHF2 Mud (M type) sheath of the NEK606 oil platform of the present embodiment comprises the component of following parts by weight:

[0022] 100 parts of HNBR, 1.5 parts of protective agent (RD and ZMB2), 5 parts of modified additive metal methacrylate, 15 parts of reinforcing agent (carbon black and white carbon black), 55 parts of compound flame retardant, reactive reinforcement 5 parts of plasticizer, 5 parts of metal oxide activator, 5 parts of peroxide curing agent.

[0023] In the HNBR, the acrylonitrile (ACN) content is 30% to 55%, the residual double bond content is 0 to 2%, and the Mooney viscosity ML1+4@100°C is 40 to 100, such as LANXESS German Lanxess fully saturated Therban A 4307, partially saturated Therban B3629, ZEON Japan Zetpol 1010L, Zetpol 2000L, etc.; the main glue used in this example is the 1:1 ratio of LANXESS Germany Lanxess fully saturated Therban A 4307 and partially saturated Therban B 3629 combination.

Embodiment 2

[0039] The NEK606 oil platform mud-resistant SHF2 Mud (M type) sheath of the present embodiment is the same as that of Embodiment 1, the difference is:

[0040] 100 parts of HNBR, 2.5 parts of protective agent (RD and ZMB2), 10 parts of modified additive zinc methacrylate, 22 parts of reinforcing agent (N330 carbon black and white carbon black), 55 parts of compound flame retardant, reactive reinforcement 5 parts of plasticizer, 5 parts of activator (ZnO+ stearic acid), 5 parts of vulcanizing agent.

[0041] In this embodiment, the composite flame retardant is ATH (aluminum hydroxide), MDH (magnesium hydroxide), and APP (ammonium polyphosphate).

[0042] The reactive plasticizer used in this embodiment is CTBN liquid hydroxybutyronitrile.

Embodiment 3

[0044] The NEK606 oil platform mud-resistant SHF2 Mud (M type) sheath of the present embodiment is the same as that of Embodiment 1, the difference is:

[0045]100 parts of HNBR, 1.5 parts of protective agent (RD and ZMB2), 15 parts of modified additive zinc methacrylate, 20 parts of reinforcing agent (N330 carbon black and white carbon black), 75 parts of compound flame retardant, reactive reinforcement 10 parts of plasticizer, 6.5 parts of activator (MgO+ stearic acid), 5 parts of vulcanizing agent.

[0046] In this embodiment, the main glue HNBR is the same as that in Embodiment 2.

[0047] In this embodiment, the composite flame retardant is APP (ammonium polyphosphate), MDH (magnesium hydroxide), and MCA (melamine cyanurate).

[0048] The reactive plasticizer used in this embodiment is HTBN liquid hydroxy-terminated butyronitrile.

[0049] The vulcanizing agent BIBP used in this embodiment is used in conjunction with TAIC (triallyl isocyanurate).

Abstract

The invention discloses a mud-resistant SHF2 Mud (M type) sheath for an NEK606 oil platform. The mud-resistant SHF2 Mud (M type) sheath comprises the following components in parts by weight: 100 parts of main body glue HNBR, 1.5-3.5 parts of a protective agent, 10-35 parts of a modified additive methacrylic acid metal salt, 15-30 parts of a reinforcing agent, 45-75 parts of a compound flame retardant, 5-15 parts of a reactive plasticizer, 5-10 parts of a metal oxide activator and 5-10 parts of a peroxide vulcanizing agent. The index of the main body glue HNBR is controlled, and the prepared cable sheath material is excellent in comprehensive performance and can adapt to the use environment of oil-based drilling fluid EDC-95-11. In the cable sheath material, the used plasticizer is a reactive plasticizer, and the reactive plasticizer participates in the reaction and cannot migrate from the material when the cable sheath is used, so that the situation that the service life is shortened due to swelling of the sheath is avoided.

Description

technical field [0001] The invention relates to a rubber material, in particular to a NEK606 oil platform mud-resistant SHF2 Mud (M type) sheath. Background technique [0002] With the continuous update of the operating environment of oil drilling platforms, the composition of drilling oil-based mud with oil as the dispersion medium has also changed. The standard NEK606 for mud-resistant cables and oil drilling platforms was upgraded in 2016. The drilling fluid was changed from the original fluid CarboSea Calcium bromide oil-based mud was changed to EDC-95-11. This oil-based drilling fluid is severely corrosive to the cable sheath and greatly reduces the service life of the cable. In the past, ethylene vinyl acetate EVA and ethylene butyl acrylate EBA were used Sheaths are difficult to meet. [0003] Chinese patent document CN109251382A (application number 201810996617.1) discloses an aging-resistant HNBR / silicon-carbon rubber composite material, its preparation method and ...
