Use required to satellite, it is difficult that satellite spoke cold light high reflective parabolic screen and processing technology thereof remain a big technology
Topic.
Summary of the invention
Present invention aims to the problems referred to above and satellite spoke cold light high reflective parabolic screen and system thereof are provided
Making technique, satellite spoke cold light high reflective parabolic screen is by reflecting surface (1), parabolic screen body (2), the parabolic screen back of the body
Plate (3) forms；Reflecting surface (1) initial point A, B lay respectively at the coordinate position in X-Z coordinate axes:
B (8.5,48.8)；A (135.3,195.8)；Parabolic curve equation is Y2=2*Z (140+1.7*Z/133.3),
Long measure is mm.
Satellite spoke cold light high reflective parabolic screen of the present invention and fabrication processing thereof be: aluminium alloy blank is cast
Make---heat treatment for the first time: be heated to 80 DEG C, it is incubated 48 hours, eliminates processing residual stress, play anti-
The only effect of deformation---line cutting roughing---heat treatment for the second time: be heated to 60 DEG C, is incubated 48 hours,
Eliminating processing residual stress---roughly grinding coarse-fine processing---heat treatment for the third time: be heated to 60 DEG C, insulation 48 is little
Time, eliminate processing residual stress, prevent deformation---fine grinding polish---the 4th heat treatment: cool to
-100 DEG C, it is incubated 1 hour, Nitrizing Treatment, improves the polishing of case hardness---the close processing of super grinding---parabola
0.025 μm is reached, in polishing process, it should be noted that control the generation of heat energy, prevent work to surface roughness
Part deformation---plating Ag reflectance coating (Ag reflectance coating thickness is 90-140 nanometer)---protective film coating (protecting film
Material is: Ag film 10-20 nanometer+Al2O3Film 10-20 nanometer+SiO2Film 60-100 nanometer), should after plated film
Ensure that the roughness of coated surface reaches 0.025 μm, thus ensure infrared reflectivity >=95%, it is seen that luminous reflectance
Rate >=93%；Meanwhile, non mirror part infrared reflectivity >=90%；Parabolic screen backboard should be protected, prevent
Oxidation；Reflectance coating must be complete with the combination of protecting film, is firmly combined with, must not have grinning effect.
