Embodiment

[0032] Example: an oil-resistant and mud-resistant radiation cross-linked flame-retardant cable material, the material formula:

[0033]

[0034] Preparation Process

[0035] The first step: Mix the ethylene vinyl acetate copolymer EVA, ethylene-vinyl acetate-carbon monoxide terpolymer, polyethylene and polyethylene grafted maleic anhydride copolymer in a high-speed mixer for 30 seconds at high speed according to the formula weight Then, it is mixed and plasticized by a twin-screw granulator. The processing temperature is: 120-130°C in the conveying section, 140-155°C in the melting section, 160-170°C in the mixing section, and 155-165°C in the exhaust section. The heating section is 155-165°C, and the head is 160-170°C.

[0036]The second step: Add the above materials into carbon black, aluminum hydroxide flame retardant, magnesium hydroxide flame retardant, silane coupling agent, cross-linking sensitizer trimethallyl isocyanate TMAIC prepolymerized by formula weight com...

Abstract

The invention relates to an oil-resistant and mud-resistant irradiation-crosslinking flame-retardant cable material. The cable material contains the following components in parts by weight: an ethylene-vinyl acetate copolymer, an ethylene-vinyl acetate-carbon monoxide terpolymer, high-density polyethylene, a polyethylene grafted maleic anhydride copolymer, carbon black, an aluminum hydroxide flame retardant, a magnesium hydroxide flame retardant, a coupling agent, a crosslinking sensitizer, an antioxidant, silicone and a lubricant, wherein the content of vinyl acetate VA in the ethylene-vinyl acetate copolymer is 33%, and the melt index of the ethylene-vinyl acetate copolymer is 0.2g / min; and the crosslinking sensitizer is a trimethyl allyl isocyanate TMAIC prepolymer, the polymerization degree n is 2-10, a monomer of the prepolymer is trimethyl allyl isocyanate TMAIC, and the molecular weight is 291.35. The cable material is low in smoke and toxic-free, the commissioned irradiation processing is simple and convenient, and the consistency of a filling and a base material in a blended material is improved, and the mechanical property of the material is improved.

Description

technical field [0001] The invention relates to the field of low-smoke, halogen-free, flame-retardant cable materials, in particular to an oil-resistant, mud-resistant, radiation-resistant cross-linked flame-retardant cable material. Background technique [0002] With the official drilling of Offshore Oil 981, China's first self-designed and built "sixth-generation deepwater semi-submersible drilling platform" in 2012, it marks a substantial step forward in the deepwater strategy of China's offshore oil industry. The technology of deep-water platforms has matured, and at the same time, higher technical requirements have been put forward for the cables used for supporting oil platforms. Special cables for oil platforms are required to have properties such as oil resistance, mud resistance, high temperature resistance, low temperature resistance, abrasion resistance, high mechanical strength, halogen-free, and low smoke due to the particularity of the environment in which they...
