Problems solved by technology

The first type of material has good oil resistance, so it has become the main material used in cables for oil platforms. However, this material has the problems of high cost and large amount of smoke when burned, which is not conducive to popularization and application; the second type of material is also because of its high cost. Not conducive to promoting the application

Abstract

The invention relates to a 125 DEG C irradiated crosslinking polyethylene low-smoke and halogen-free flame retardant polyolefin jacket material used for oil platform, which consists of base material, a compatilizer, a halogen-free flame retardant, a antioxidant, a lubricant and a crosslinking sensibilizer with the weight portions as follows: 60 to 80 portions of base material, 20 to 40 portions of compatilizer, 100 t o150 portions of halogen-free flame retardant, 2 to 4 portions of antioxidant, 0.5 to 2 portions of lubricant as well as 1 to 4 portions of crosslinking sensibilizer. The 125 DEG C irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin jacket material used for oil platform has the advantages of relatively lower cost, no halogen contained in the whole system, low smoke quantity when in combustion and the like, and completely meet the requirements of the cables used for 125 DEG C oil platform.

Description

technical field [0001] The invention relates to a polymer material for electric wires and cables, in particular to a 125°C irradiation cross-linked low-smoke, halogen-free, flame-retardant polyolefin sheathing material for oil platforms. Background technique [0002] The operating environment on offshore oil platforms is very harsh. Therefore, in addition to high-strength mechanical properties, wear resistance, moisture resistance, and high-efficiency flame-retardant properties, wires and cables for offshore oil platforms must also have good low temperature (-55°C) ) Soft performance and electrical stability for long-term work in water at 75°C and 90°C. In addition, in order to prevent wires and cables from producing a large amount of toxic hydrogen halide gas and smoke in case of accidental fire and prevent secondary hazards, wires and cables for offshore oil platforms should also have low-acid, low-halogen and low-smoke properties. [0003] At present, there are two main ...
