Preparation of Infrared Stealthy Coatings

Abstract

Two kinds of microcapsules were synthesized with paraffin and the mixture of n-butyl stearate and n-tetradecyl alcohol as the core material, and the melamine-formaldehyde (MF) resin as shell material, respectively. In this way, the infrared stealthy coatings were prepared by using the as-synthesized microcapsules, the hollow glass microspheres and other auxiliaries. The surface morphology of the microcapsules were investigated by using scanning electron microscopy (SEM). By using the contactless infrared thermometer measurement and radiation rate test device, the radiation exitances of coatings were determined. The radiation exitance of infrared stealthy coatings is lower than the common coatings, which improved the performance of infrared stealthy of destination.
