Abstract:Fluorine resin/aluminum infrared coating is prepared with aluminum black color pulp as filler and fluorine resin as binder. The effect of black color pulp content on the performance of fluorine resin/aluminum infrared coating is investigated. Performance tests include glossiness, color aberration, infrared emissivity, hardness, adhesion, impact resistance, roughness, optical testing, corrosion resistance, etc. The results show that when the content of black color pulp is 1.0%, the performance of the whole fluorine resin coating is the best. When the content of black color pulp increases from 1.0% to 9.0%, the surface glossiness of the coating decreases continuously. The ΔE value of the coating decreases. Infrared emissivity of coating surface increases gradually. The hardness of the coating is 6H. The adhesion of the coating is grade 0, and the absorption peak of infrared spectrum gradually enhances. When the content of black color pulp is 0%―3.0%, the impact resistance is higher than 50 kg·cm, and the impact resistance is high. When the content of black color pulp is 0%―5.0%, the surface roughness of the coating is low. When the black color pulp content is 1.0%, the corrosion resistance of the coating is the highest.
