Description
Technical field
The present invention relates to a kind of preparation method of cable jacket material, particularly a kind of generation Ⅲ nuclear power station harsh and unforgiving environments cable jacket material and preparation method thereof.
Background technology
Nuclear energy is as the energy of new generation, there is the advantage that other energy much is incomparable, not only can not damage environment, and nuclear fuel energy density is compared with high millions of times of fossil oil, transport and store all very convenient, so Development of Nuclear Energy Power Plant is very necessary for China and has scape in face of light.Growing along with society; our country is also faced with the day by day deficient circumstances of coal, oil, Sweet natural gas equal energy source fuel; nuclear energy is as efficient, clean energy, not only in security, stability and all have clear superiority in the protectiveness of environment; or a kind of more economic energy; it at present just crosses implementation progressively and development at me, will become the energy pillar of a new generation future.
The Construction of Nuclear Electricity of current China enters high-speed development period, generation Ⅲ nuclear power, as US Westinghouse company AP1000 nuclear power generating sets, in three construction of China.China also proposes to plan that following advanced core gathers the system development work of fission energy (forth generation nuclear power generating sets) simultaneously.No matter be the third generation or the 4th generation of technology such as nuclear energy system, the cable of nuclear power and the insulating material of cable accessory thereof all must have excellent long term heat ageing performance (heat life >=90 DEG C × 60 years), stable radiation-resistant property and the feature such as electric property, good fire-retardant and low cigarette, Halogen, low toxicity.The base material of cables of nuclear power insulating material is mostly the material such as polyethylene, cross-linked polyolefin usually, these traditional cable insulating materials can produce a large amount of HCL gas in accident, form smog, become the first cause of loss of life and personal injury in fire, therefore the low-smoke non-halogen flame-retardant performance of cable jacket material seems particularly important.Under Nuclear power plants LOCA accident conditions, the High Temperature High Pressure produced in short-term is impacted has extremely strong destructiveness to the coat layer of power cable, causes restrictive coating to corrode, degradation under electric property.Current China prior art is all improved on the thermoplastic low-smoke halide-free material in 40 year life-span, but difficulty is very large.Three generations's nuclear power requires reach more than 60 years work-ing life, proposes requirements at the higher level to temperature resistant grade long term heat ageing.Therefore adopt thermosetting material will become trend as base material.
Summary of the invention
The object of the invention is to for China's the deficiencies in the prior art, there is provided a kind of performance more superior, when Long-term service temperature 90 DEG C, reach work-ing life more than 60 years, be applicable under the harsh and unforgiving environments of generation Ⅲ nuclear power station with cable jacket material and preparation method thereof.
For achieving the above object, the technical scheme that the present invention takes is:

The preparation method of described modified filler is as follows: the ratio of a, in mass ratio 3-6:2-4:1 takes baddeleyite, the tremolite, Water Quenching Slag, mix, pulverize, cross 100-150 mesh sieve, then add water and make the suspension that concentration is 50-60%, add the sorbitol polyoxyethylene ether cocounut oil acid esters being equivalent to the α-sodium olefin sulfonate of suspension weight 4-6%, the Monododecylphosphate trolamine of 3-4% and 2-3%, heating in water bath is to 50-60 DEG C, 400-500r/min stirs 15-20min, filter, dry; B, to get the volume fraction being equivalent to the powder weight 3-4 times amount that step a obtains be the aqueous ethanolic solution of 90%, then add and be equivalent to vinyl three ('beta '-methoxy oxyethyl group) silane of the powder weight 1-2% that step a obtains and sec.-propyl three (dioctylphyrophosphoric acid acyloxy) titanic acid ester of 0.5-1%, heating in water bath is to 40-50 DEG C, 200-300r/min stirs 20-30min, filter, dry.
By the preparation method of cable jacket material under the harsh and unforgiving environments of generation Ⅲ nuclear power station, comprise the following steps:
The first step: batching
According to above-mentioned formula constituent weight weighing and burden on electronic scales.
Second step: once mixing
According to the number that above-mentioned formula constituent is weighed according to the first step, ethylene vinyl acetate, inorganic combustion inhibitor, synergistic flame retardant, anti-aging agent, antiradiation agent, stablizer, lubricant, vinyl silicane coupling agent are dropped into Banbury mixer mixing, Banbury mixer temperature at 80-100 DEG C, banburying 3-5 minute; Compound is routed up, proceeds to the clot of mill thin-pass, then mixing film is parked 6-8 hour;
3rd step: secondary is mixing
Mixed once film, linking agent, additional crosslinker, modified filler are dropped in Banbury mixer, put down floating weight, banburying temperature controls at 60-80 DEG C, banburying 40-50 second, is routed up by compound, proceeds to the clot of mill thin-pass.
4th step: roll over page slice
The film broken into after thin-pass is dropped into three rollers and roll over page machine, and six cooling drums are opened sufficient water coolant, by the film after cutting once through eight cooling drums, then through insulating powder groove, finally making width is 20-30mm, and thickness is the film of 0.4-0.6mm;
Generation Ⅲ nuclear power station harsh and unforgiving environments cable jacket material product is obtained by above four steps.
