Research on Preparation and Performance of Adaptive Color-changing Camouflage Coating
In order to effectively improve the demand for rapid integration of equipment with different backgrounds in the field,the adaptive thermochro-mic camouflage coating was prepared by a screen printing method which is conducive to large-scale production and low cost.By using fluo-rocarbon resin and acrylic resin to cover color-changing materials,the coating preparation system and preparation process were studied,and the reversible color-changing camouflage coating with application prospect was prepared by testing the properties of color-changing coatings.In this study,the rapid reversible adaptive change of camouflage coating was realized by the joint action of heating auxiliary layer and color-changing coating.The physicochemical properties of the coating were tested by means of colorimeter,universal tensile testing machine,water fastness tester and salt spray tester.The test results show that the thermochromic camouflage coating prepared by polyurethane resin system has a pro-mising application prospect.When the camouflage coating thickness is 0.6 mm,the coating discoloration time is 6-9 seconds.The application of color-changing camouflage coatings in forested and desert environments yields detection rates of 0.51 and 0.56,respectively.
