China's cable industry has started the research and development work of cables of nuclear power and material therefor in the eighties of last century middle and later periods eighties, the evolution of cable for nuclear power station is in fact the update process of cable material.According to the requirement of nuclear power cable performance, cable material used, except possessing good electric property and mechanical and physical performance, the most important thing is also to have good radiation resistance and LSOH anti-flaming performance etc.
In the research of current radiation hardness halogen-free flame-retardant cable material, the raising of radiation resistance mainly by adding radioprotective auxiliary agent to realize in base resin.From being subject to high-energy radiation, polymkeric substance there is the analysis of chemical transformation, macromole is accepted to excite the primary reaction that generates free radical after radiation, be one of macromolecular chain most important reason that follow-up crosslinked or DeR occurs, and then cause polymer architecture generation noticeable change, performance degradation.Therefore, improve macromolecular material radiation resistance and can catch macromole and be subject to the free radical producing after radiation by adding oxidation inhibitor to realize in polymkeric substance, block further cracking, the unfavorable chemical reaction such as crosslinked.But this method effect under inert atmosphere or vacuum environment is better, and when having oxygen to exist, effect can be greatly affected, and need to add more substantial antioxygen auxiliary agent, and this may have a negative impact to other performances such as insulating property of cable material.In addition, can also be by add the auxiliary agent of some energy absorbing radiation in cable material, high-energy radiation is converted into heat dissipation through intermediates, also can effectively improve the radiation hardness ability of material, this analog assistant that can adopt is as aromatic hydrocarbon oil, oxidation and containing the synthetic fat quasi-molecule of phenyl ring.But, conventional small molecules radioprotective auxiliary agent is conventionally unbound state and is dispersed in material, easily under the effect of radiation and high temperature, from material, overflow, thereby cause the radiation resistance of material to decline, and may bring disadvantageous effect to the flame retardant properties of material and insulating property.
And current domestic halide-free low-smoke fireproof cable material generally adopts metal hydroxides as fire retardant, it has advantages of that safety, environmental protection, the amount of being fuming are little, but in order to reach satisfied flame retardant effect, must add this class inorganic combustion inhibitor of q.s, generally need more than 50%.So a large amount of inorganic combustion inhibitors, in cable material base resin, be difficult to disperse, mix, cause cable material to be difficult to machine-shaping, physical and mechanical properties significantly declines.Therefore, to have the cable material of the good over-all properties such as radiation hardness, LSOH anti-flaming be the challenge problem of cable industry in development.
