黑色色浆对氟树脂/铝红外涂层性能的影响
|
摘要
以铝、黑色色浆为填料,氟树脂为粘合剂,制备了氟树脂/铝红外涂层,研究了黑色色浆含量对氟树脂/铝红外涂层性能的影响。性能测试包括光泽度、色差、红外发射率、硬度、附着力、抗冲击性、粗糙度、光学测试、耐腐蚀性等。结果表明,在黑色色浆含量为1.0%时,整个氟树脂涂层的性能最优。当黑色色浆的含量由1.0%上升到9.0%,涂层表面光泽度不断下降,涂层ΔE值不断减小,涂层表面红外发射率逐渐升高,涂层的硬度都是6H,涂层的附着力等级为0级,红外光谱吸收峰逐渐增强。当黑色色浆含量为0%～3.0%,抗冲击性都超过50 kg·cm,抗冲击性较大。当黑色色浆含量为0%～5.0%时,涂层表面粗糙度比较低。当黑色色浆含量为1.0%时,涂层的耐腐蚀性能最佳。
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 6 H. 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.
