Research of Strontium Silicate Modified Zinc Oxide Thermal Control Coatings

Abstract:

Thermal control coatings (TCCs) play an important role in thermal management of spacecrafts and satellites by their thermo-optical properties. In this research, the novel TCCs were prepared by incorporating the self-made strontium silicate and zinc oxide into the potassium silicate binder. The effects of strontium silicate on phase composition, microstructure and optical performance of TCCs were studied using scanning electron microscope and spectroreflectometer. The results show that: strontium silicate can improve near infrared band (1000~2400nm) spectra reflectance. Compared with traditional zinc oxide TCCs, the novel composite coatings enhance the reflectance , and improve the optical properties.
