Effect of Black Paste on the Property of Fluorine Resin/Aluminum Infrared Coating

Abstract

A fluorine resin/aluminum infrared coating was prepared with aluminum using black paste as filler and fluorine resin as binder. The effect of the black paste content on the performance of gloss, color difference, infrared emissivity, hardness, adhesion, impact resistance, roughness, optical testing, and corrosion resistance of the fluorine resin/aluminum infrared coating were examined. When the content of black paste was increased from 1.0% to 9.0%, the gloss of the coating surface decreased; the ΔE* value of the coating decreased; the infrared emissivity of the coating surface increased gradually; the hardness of the coating was 6H; the adhesion grade of the coating was 0; the infrared absorption peak increased gradually. When the content of black paste was 0%–3.0%, the impact resistance was more than 50 kg∙cm, and the impact resistance was higher. When the content of black paste was 0%–5.0%, the surface roughness of the coating was relatively low. When the content of black paste was 1.0%, the corrosion resistance of the coating was the best. The results showed that when the content of black paste was 1.0%, the performance of the whole fluorine resin coating was the best. Through the preparation and characterization of fluorine resin infrared low-emissivity coatings, the possibility of applying fluorine resin to infrared low-emissivity anticorrosive coatings was discussed, which laid a foundation for the subsequent engineering application of coatings.

Preparation and Characterization of Low Infrared Emissive Aluminum/Waterborne Acrylic Coatings

“…Al powder concentration was too low which would lead to higher emissivity of coatings. Due to the strong reflectivity and gloss of Al powder, high concentration of Al powder will lead to higher gloss of coatings, which is not conducive to compatibility with visible light [31]. Therefore, 30.0% of Al powder was selected for comprehensive performance, and the concentration of Al powder was fixed to 30.0% in the following independent experiments.…”

Effect of Different Color Paste on Properties of Fluorine Resin/Aluminum Infrared Low Emissivity Coating

“…Infrared coating is required to have the following properties at the same time: low emissivity, environmental protection, good corrosion resistance, low gloss, so as to have a good effect on visible light compatibility. Fluorine resin is environmentally acceptable, not only has the high surface hardness, good adhesion, and corrosion resistance [7,8], but also can increase the water contact angle of the coating to achieve superhydrophobic properties [9][10][11].…”

The Impact of Coating Ingredients on the Aging Resistance of Topcoat Paints by Model Trees

“…Resin and pigment are the two main ingredients of paints. Many recent studies attempted to explore the individual impact of resin [8][9] or pigment [10][11][12][13][14]. These two ingredients can also be considered together to determine the performance of coatings [15][16][17].…”
