Embodiment Construction
[0042] The preparation method of the present invention is specifically described below. In this method, when preparing the oil pipeline, firstly, the inner rubber layer is prepared, and the process of preparing the inner rubber layer includes using a sheet of hydrogenated nitrile rubber as a material, winding three layers of hydrogenated nitrile rubber with a predetermined inner diameter, and the three layers of hydrogenated nitrile rubber The total thickness of the rubber is 2.2-2.8mm, and the hydrogenated nitrile rubber is added with semi-reinforcing carbon black. Moreover, the hydrogenated nitrile rubber undergoes vulcanization treatment with metal oxides and peroxides as the vulcanization accelerator system, and softening treatment with the plasticizer with cold resistance as the softening system, and the hydrogenated nitrile rubber is added with a binder.
[0043] Preferably, the total thickness of the three layers of hydrogenated nitrile rubber is 2.5 mm, and the outer d...

Abstract
The invention provides a method for preparing an oil pipeline used for inter-ship replenishment. The main material of the inner rubber layer of the rubber hose produced by the method of the invention is oil-resistant hydrogenated nitrile rubber. The hydrogenated nitrile rubber has good oil resistance and softness, and has good extrusion resistance under high pressure. When preparing the outer rubber layer, the rubber-plastic alloy with good oil resistance, ozone resistance and ultraviolet aging resistance is selected as the rubber type for the outer coating of the pipe. The vulcanization system uses metal oxides and sulfur as the vulcanization system, thiazole accelerators and thiuram accelerators as the vulcanization acceleration system, and antiozonant as the protection system to increase the anti-ozone and ultraviolet aging of the rubber. The oil delivery hose prepared by the invention has the advantages of light body, good bending performance, high bearing strength, high tensile strength, good electrical conductivity, good wear resistance, resistance to marine environment and good sealing performance.
Description
technical field [0001] The invention relates to the field of oil material transportation, in particular to a method for preparing an oil transportation pipe. Background technique [0002] The implementation of replenishment at sea is a situation that often occurs during the navigation of ships. The existing oil delivery hose has poor bending performance during liquid cargo supply, and is easy to be discounted, resulting in a large loss of fluid resistance; moreover, the existing oil delivery hose has poor wear resistance and is easy to be damaged; The sealing performance is not good; the bearing strength is low, that is, the working pressure is low; the anti-aging performance is poor. Contents of the invention [0003] In view of the above problems, the present invention proposes a hose preparation method. The oil delivery hose prepared by this method can transport diesel oil, fuel oil, jet fuel, etc., and has a light pipe body, good bending performance, high bearing stre...
