Description
Technical field
The invention belongs to the material engineering field, be specifically related to a kind of tungsten-high molecular polymer matrix material and preparation method thereof.
Background technology
The reactor of nuclear power plant is a huge radioactive source; When fuel fission, can produce neutron and gamma-radiation; The activation products that fissium that fission reaction produces and priming reaction produce also can produce α, β and gamma-radiation when decaying, and therefore, the Nuclear power plants facility has very big potentially dangerous property; Must carry out radiation shielding to it, to avoid the generation of various possibility accidents.Simultaneously, the processing of nuke rubbish is also most important.Low-activity nuke rubbish and high radioactive nucleus waste were two types during usually said nuke rubbish comprised; The former refers to mainly that Nuclear power plants produces in power generation process has radioactive waste liquid, refuse; 99% of all nuke rubbish have been accounted for; The latter then is meant the nuclear fuel after the burning that from nuclear power plant reactor core, swaps out, because it has the height radioactivity, being commonly called as is that height radiates waste material.When above nuke rubbish is carried out harmless treatment, also need carry out necessary radiation shielding and handle.
Mostly radiation shielding material is metallic lead in the prior art; Its shield effectiveness is good, cost is low and be easy to processing; Yet, plumbous own toxic, atmosphere pollution, water source and farm crop such as plumbiferous waste gas, waste water, waste residue; Can jeopardize near resident, it is imperative therefore to replace lead to be applied to the nuclear radiation shield field with other material.
Research shows that a kind of radiation protection ability of material is relevant with its ordination number and density of material, and ordination number is high more, density of material is big more, and then shielding properties is good more.The ordination number of tungsten is 74, and density is 19.35g/cm
3, have good beta ray shield performance, be the choosing that is used for doing the best of shielding material, but tungsten is the HMP refractory metal, its shaping processing difficulties is easy to receive shape limits when using.Being matrix with the polymkeric substance in the prior art, is that filler prepares high density tungsten-polymer composites and solves the problems referred to above with the tungsten powder, and patent US5001354 is that the surgical glove of feedstock production has shielding property with nature rubber latex and tungsten powder.Patent US7304105B2 produces a kind of radioprotective matrix material with the tungsten powder filled elastomer of different-grain diameter; This material has good snappiness and processing characteristics; But the tungsten powder that needs three kinds of different-grain diameters is arranged in pairs or groups mutually and is improved the tonburden of tungsten, and ME is complicated.Employed tungsten powder normally makes through traditional grinding techniques such as ball millings in the prior art; The tungsten powder particles serious agglomeration that makes like this; Out-of-shape, flowability and density are relatively poor, and the tonburden in matrix material is lower; Be not easy to homodisperse in macromolecule matrix, cause the matrix material physical and mechanical properties relatively poor.
