利用工业原料聚苯硫醚微粉和疏水性二氧化硅纳米粉末,采用喷涂法在瓷砖表面制备了疏水复合涂层.研究了热处理温度、组分配比对涂层表面形貌、粗糙度和接触角的影响,发现随着热处理温度升高,涂层表面粗糙度增大,随着疏水性二氧化硅含量的增加,由于表面聚集的疏水性二氧化硅增多,涂层疏水性增强,在热处理温度为280℃、疏水性二氧化硅与聚苯硫醚质量比为1∶1时,可获得超疏水涂层,涂层的接触角大于150°,滚落角小于4°,pH值为1～14的水溶液在其表面都具有很高的接触角.超疏水涂层具有良好的自清洁效果,并且经落沙法实验测定,超疏水涂层耐刮伤性能良好.
Hydrophobic composite coating was prepared on the surface of ceramic tile by using industrial raw polyphenylene sulfide powder and hydrophobic silica nanopowder.The effects of heat treatment temperature and composition ratio on the surface morphology, roughness and contact angle The results showed that with the increase of the heat treatment temperature, the surface roughness of the coating increased. With the increase of the hydrophobic silica content, the hydrophobicity of the coating increased due to the increase of hydrophobic silica aggregated on the surface, Is 280 ℃, the hydrophobic silica and polyphenylene sulfide mass ratio of 1: 1, the superhydrophobic coating can be obtained, the contact angle of the coating is more than 150 °, the roll angle is less than 4 °, the pH is 1 ~ 14 aqueous solution has a very high contact angle on its surface.The superhydrophobic coating has a good self-cleaning effect, and the desiccation test determined that the super hydrophobic coating has good scratch resistance.
