Example Embodiment

[0026] Example 1

[0027] Weigh the specific raw materials according to Table 1. The preparation steps are as follows:

[0028] (1) Add EPDM rubber, polyperfluoroethylene propylene resin, silicone montmorillonite, basic magnesium phosphate whiskers, calcium sulfate whiskers, and carbon black into the high-speed mixer, heat up to 85 degrees Celsius, and knead for 20 minute;

[0029] (2) Add the remaining raw materials to the mixture in step (1), continue kneading for 15 minutes, discharge the materials to the cooling mixer for cooling, and discharge when the temperature is lower than 50°C;

[0030] (3) Set the extrusion temperature of the twin-screw extruder to 190 degrees Celsius, and the screw speed to 125 rpm. Add the product obtained in step (2) to the twin-screw extruder for extrusion and granulation, and the pellets are cooled At room temperature, reject defective products are screened and packaged to obtain the corrosion-resistant cable material.

Abstract

The invention relates to the technical field of materials, in particular to an ethylene propylene diene monomer insulated cable material for an oil-submerged pump cable and a preparation method. The insulated cable material is composed of ethylene propylene diene monomer, fluorinated ethylene propylene resin, aluminum hydroxide, polysiloxane, organic silicon montmorillonite, carbon black, calciumsulfate whiskers, basic magnesium sulfate whiskers and zinc stearate. By selecting proper components, adjusting the content of the components and optimizing the preparation process, the material withhigh strength, high oil resistance, good flame retardance and excellent insulativity is obtained. And when applied to a cable of an oil-submerged pump, the service life of the cable can be effectivelyprolonged, and the safety of the cable is improved.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an EPDM insulating cable material for submersible oil pump cables and a preparation method thereof. Background technique [0002] The submersible pump power cable is a special cable used in conjunction with the submersible electric pump unit. It is different from ordinary power cables. It is often laid in oil wells. The working conditions in oil wells are harsh, and they are often located in highly corrosive environments such as high temperature, high pressure, and oil and gas. Among them, the requirements for oil resistance and high temperature resistance of this type of cable are very high. At present, domestic submersible pump cables are mostly made of ethylene-propylene rubber and nitrile rubber, while the heat resistance of ethylene-propylene rubber can only reach 90°C, and the oil resistance is also poor; although nitrile rubber has excellent oil resistance, it is resista...
