Description
Technical field
The present invention relates to a kind of radiation shield paster, particularly relate to a kind of anti-radiation shield paster for geo-synchronous orbit satellite.
Background technology
Satellite is period in-orbit, inevitably meets with the radiation of various space charged particle.Electronics in space radiation environment, proton in the devices accumulation for a long time can produce ionisation effect in the semiconductors, cause device electrical performance Parameters variation, cause equipment operation irregularity.Therefore, for ensureing that because of Space Radiation Effects do not cause satellite damage or lost efficacy in orbit by period for satellite, countries in the world are in satellite development process, all need the charged particle radiation environment according to satellite real-world operation track, to satellite surface and more inner to the key equipment of space radiation sensitivity or parts, adopt the mode of paster or coating to carry out actv. shadow shield, namely intrinsic according to device radioresistance total dose index request carries out specific aim shielding, to extend the service life of satellite.Chinese utility model patent CN2427435Y discloses a kind of anti-single particle effect emission shield, this shielding part is made up of the white pottery porcelain of stratiform closed assembly and one side polyamide film of aluminizing, the single particle effect degree that space radiation environment produces Spacecraft Electronic device can be reduced, reduce its harm.But this shielding part thickness is comparatively large, and heavier-weight, is unsuitable for the application of space device.
Summary of the invention
The present invention is intended to overcome above-mentioned defect, a kind of anti-radiation shield paster for geo-synchronous orbit satellite is provided, particularly, comprise titanium coating, metal/polymer composite material layer, aluminum metal layer, it is characterized in that described metal/polymer composite material layer comprises metal powder and phenol resin and curing agent, described metal powder comprises tantalum, titanium and aluminium, by weight, described metal/polymer composite material layer comprises the metal powder of 70%, the phenol resin of 27% and the curing agent of 3%, metal powder comprises the tantalum that weight ratio is 4: 2: 1, titanium and aluminium, curing agent is preferably Diethylenetriamine.
Preferably, the thickness of titanium coating, metal/polymer composite material layer, aluminum metal layer is respectively 1 millimeter, 0.5 millimeter and 1 millimeter.
Preferably, the preparation method of metal/polymer composite material layer is: take the tantalum of 40 grams, 20 grams, 10 grams, titanium and aluminium powder respectively, put into ball grinding mill, be milled to granularity 1-50 micron; Take 27 grams of phenol resins, be heated to 65 degrees Celsius, aforementioned metal powder is mixed into phenol resin, stir 20 minutes, add 3 grams of curing agent after being cooled to room temperature, be transferred in mould, curing molding between 80-100 degree Celsius.
Radiation shield paster thickness according to the present invention is thin, quality light, has good shield effectiveness.
Detailed description of the invention
Radiation shield paster according to the present invention is three-decker; comprise titanium coating, metal/polymer composite material layer, aluminum metal layer from outside to inside successively relative to claimed electronics package, that is aluminum metal layer more presses close to claimed electronics package and the material layer bonding with it.The bonding one-tenth plate of adhesive agent can be adopted between three-decker.Preferably, the thickness of titanium coating, metal/polymer composite material layer, aluminum metal layer is respectively 1 millimeter, 0.5 millimeter and 1 millimeter.
Preferably, described metal/polymer composite material layer comprises metal powder and phenol resin and a small amount of curing agent, and described metal powder comprises tantalum (Ta), titanium and aluminium.Preferably, metal/polymer composite material layer comprise the metal powder of 70%, the phenol resin of 27% and 3% curing agent, metal powder comprises tantalum, titanium and the aluminium that weight ratio is 4: 2: 1, and curing agent is preferably Diethylenetriamine.
The preparation method of metal/polymer composite material layer is: take the tantalum of 40 grams, 20 grams, 10 grams, titanium and aluminium powder respectively, put into ball grinding mill, be milled to granularity 1-50 micron; Take 27 grams of phenol resins, be heated to 65 degrees Celsius, aforementioned metal powder is mixed into phenol resin, stir 20 minutes, add 3 grams of curing agent after being cooled to room temperature, be transferred in mould, curing molding between 80-100 degree Celsius.
Because first outermost titanium material can make most of energy particle underspeed, then intermediate composite produces very large interception to bremsstrahlung, and the aluminum of innermost layer can absorb secondary electron and the bremsstrahlung of interlayer generation, because which form a kind of good shielding construction.
