Strontium Silicate

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.

Control Principle

As a kind of white paint, ZnO/silicone thermal control coatings are used commonly in space. In order to implement more effective thermal control in space, nanotitanium dioxide was doped to the coatings. In this paper, different percent of nanotitanium dioxide was appended to the coatings, and thermal control principle was discussed. Optical properties of these coatings were discussed by spectrophotometry and infrared reflectometer. The experimental results show that solar absorptance (αs) of nanotitanium dioxide doped ZnO/silicone thermal control coating is lower in all wavelength region than the coatings without doping, especially in visible region and infrared region. The total solar absorptance of 1% nanotitanium dioxide doped coating is 0.09, which decreases by 36% than the undoped coating..
