Abstract

The invention discloses an irradiation crosslinking wearing-resistant low-torque low-smoke halogen-free flame-retardant cable sheath material for a nuclear power station cable and a preparation method and a cable product of the material. The irradiation crosslinking wearing-resistant low-torque low-smoke halogen-free flame-retardant cable sheath material for the nuclear power station cable consists of the following components: an ethylene-vinyl acetate copolymer (EVM), an ethylene-octylene copolymer (POE), ultra-high molecular weight polyethylene (UHMWPE), polyvinylidene fluoride (PVDF), a compatilizer, a flame retardant, a flame retardant synergist, irradiation resistant aids, a composite antioxidant, crosslinking aids and a lubricant. After irradiation crosslinking, a wire cable product made of the cable sheath material has very good properties of oil resistance, wearing resistance, torque resistance, flame retardancy and the like, is very excellent in long-term aging resistance, excellent in irradiation resistance, meets requirements of nuclear power stations of a third generation on a service life of 60 years (90 DEG C), and can be used in harsh environments of the nuclear power stations.

Description

technical field

[0001] The invention belongs to the field of low-smoke and halogen-free sheathing materials for nuclear power plants, and in particular relates to a radiation-crosslinked, wear-resistant, torque-resistant, low-smoke, halogen-free, and flame-retardant cable sheathing material for nuclear power plant cables, a preparation method thereof, and a cable product. Background technique

[0002] As a clean energy, nuclear power is one of the main directions of energy development in the future society. According to the 13th Five-Year Plan for Electric Power issued by the National Energy Administration, the general principle is to "accelerate adjustment and optimization, transform and upgrade, and build a clean, low-carbon, safe and efficient modern power industry system". An important part, status is also very important.

[0003] After decades of development, nuclear power technology has entered the third generation. The third generation of nuclear power puts forward h...
