The invention relates to a
pigment, a preparation method, a
thermal control coating containing the
pigment and a preparation method. MgZnO / SiO2 core-shell
nanostructure composite
powder is used as the
pigment, and after the pigment is mixed with inorganic
silicate, a solar full-spectrum high-reflection
thermal control coating is prepared. MgZnO is used as a core of the MgZnO / SiO2 core-shell composite
powder, and the surface of the MgZnO / SiO2 core-shell composite
powder is coated with a SiO2 shell layer, so that the high reflection of the
thermal control coating in an
ultraviolet band is realized, and meanwhile, the possibility is provided for improving the
spatial stability of the coating. Through reasonable formula design and spraying
process control, the prepared solar full-spectrum high-reflection thermal control coating is compact in paint film and good in
binding force, and the
engineering application technical problems that a coated product is rough in surface appearance, prone to powder falling and the like are solved. The bonding force of the thermal control coating and a non-
metal base material is improved, good thermal matching of the coating and different types of base materials is achieved, the thermal control requirements of medium and low
orbit long-life
spacecraft model products are met, and the thermal control coating has potential application prospects in the civil field.
