Effect of the Content of Paraffin Microcapsule on the Thermal Performance of Infrared Camouflage Coatings

Abstract

As the phase change material, paraffin microcapsule thermal performance of infrared camouflage coatings were studied, With blank contrastive experiments and changing the content of paraffin microcapsule, it is studied the thermal performance of infrared camouflage coatings. This study has shown that there has a high performance of storing and retaining the caloric of the infrared camouflage coatings, with the temperature 7°C. The content of paraffin microcapsule has a great effect on the infrared thermal performance in coating, the higher content of paraffin microcapsule, the better thermal performance of storing and retaining the caloric. The difference of the temperature can reach the highest value at 7°C between 35% or 40% and 25% paraffin microcapsule in the coatings.
