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 ofcompatilizer, 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
The present invention relates to a kind of electric wire macromolecular material, more particularly, relate to 125 ℃ of irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin jacket materials of a kind of used for oil platform.
Background technology
Operating environment on the offshore platform is very abominable, therefore, offshore platform with electric wire except must having high-strength mechanical performance, abrasion resisting performance, humidity resistance, high efficiency flame retardance, the electric stability energy that good low temperature (55 ℃) softness also must be arranged and in 75 ℃ and 90 ℃ of water, work for a long time.In addition, produce a large amount of poisonous hydrogen halides and smog when the unexpected fire, prevent secondary harm that for fear of electric wire offshore platform also should have low acid, low halogen and low smoke performance with electric wire.
The oil resistant cable base material that can be used for offshore platform at present mainly contains following two classes: the mixture of (1) chlorosulfonated polyethylene rubber, paracril; (2) silicon rubber, tetrafluoroethylene or their mixture.First kind material oil-proofness is good, thereby becomes the material that the used for oil platform cable mainly uses, but this material exists cost height, the big problem of when burning amount of being fuming, and is unfavorable for applying; The second class material also is unfavorable for applying because cost is too high.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide the relatively low and well behaved used for oil platform of a kind of cost 125 ℃ of irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin jacket materials.
The present invention has adopted following technical proposals to solve above-mentioned technical problem:
125 ℃ of irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin jacket materials of a kind of used for oil platform are made up of base material, compatilizer, halogen-free flame retardants, oxidation inhibitor, lubricant and crosslinking sensitizer, and the mass fraction of each feed composition is as follows:
