Technical field
The present invention relates to nuclear industry technical fields, and in particular to a kind of disperse filled composite function metallic insulation.
Background technique
When nuclear reactor operates normally, inside core level-one main equipment and pipeline to flow high temperature, high pressure, high radioactivity cold
But medium needs to be thermally shielded in equipment and pipeline external surface setting insulating layer, reduces thermal loss, while being also required in core one
Shielding material is arranged to reduce the dose of radiation of equipment periphery in grade equipment and pipeline external, facilitates the inspection of personnel's in-service period
Maintenance.Currently, the first device and pipeline external of nuclear reactor coolant system usually all use metallic insulation, but this gold
Belong to insulating layer and only have incubation and thermal insulation function, does not have function of shielding, such as: patent US3904379A, CN1159062A,
The metallic insulation that CN203131332U is provided does not have function of shielding.But with the development of nuclear power technology, both bands are protected
Warm heat insulating function, the demand of nuclear leve equipment and pipe insulating layer with function of shielding is more obvious again, patent CN103174912B
A kind of compound insulating layer with function of shielding is respectively provided with CN103971761A, but the shielding material of the two all uses
Boracic silicone resin or the nonmetallic organic material such as Boron-containing-PE plate or boracic epoxy resin board, this kind of nonmetallic organic screen material
The Applicable temperature range of material is generally not above 200 DEG C, even under the working environment lower than 200 DEG C, for organic resin
The inherent characteristic of material itself limits, and this kind of nonmetallic organic shielding material will necessarily generate under high temperature, prolonged use
Ageing of performance causes its function of shielding to be gradually reduced and even loses, and a service life will not be very long, is being used for the super-long service life phase
Nuclear power plant and when nuclear-plant (such as 60 year phase in longevity), be necessarily required to periodic replacement to guarantee that its shielding properties meets always
It is required that.
Summary of the invention
The technical problems to be solved by the present invention are: the composition metal insulating layer with radiation shield function is adopted in the prior art
