Zusammenfassung: | In order to obtain coatings with low emissivity, most studies focus on the screening of resin and filler components. However, the influence of process parameters on emissivity during the coating preparation process was rarely studied, and the interaction between various preparation processes was not analyzed. In this study, aluminum powder was selected as the metal filler and fluorocarbon resin was selected as the adhesive to prepare a low-infrared emissivity coating. Initially, single-factor experiments were conducted to regulate the viscosity of the coating(achieved by varying the amount of diluent added to the coating), the wet film thickness of the coating and the curing temperature. The combined effects of these three process parameters on the distribution of aluminum powder in the coating and the infrared emissivity of the coating were analyzed and studied. The response surface methodology was used to further analyze the interactions between the process parameters, and the optimal combination of process |
