摘要 通过丙烯酸原位聚合包覆片状铝粉制备水性铝颜料,考察丙烯酸、过硫酸铵、异丙醇和水的用量、反应温度和反应时间对颜料的缓蚀效率和涂膜光泽度的影响。结果表明:在丙烯酸、过硫酸铵、异丙醇、水和片状铝粉的质量比为0.15:0.075:0.5:25:1,95℃反应0.5h的条件下,制备的水性铝颜料缓蚀效率达99.3%,涂膜光泽度为88.3Gs。通过扫描电镜、激光粒度分析和红外光谱对水性铝颜料进行表征,结果表明水性铝颜料表面包覆了聚丙烯酸。 In order to prepare waterborne aluminum pigments,the flaky aluminum powders were coated with polyacrylic acid through in-situ polymerization.The effects of dosage of acrylic acid,ammonium persulfate,isopropanol and water,reaction temperature and reaction time on corrosion inhibiting efficiency and coater gloss of pigment were experimentally investigated.The results show that when waterborne aluminum pigments are prepared under conditions of mass ratio of acrylic acid,ammonium persulfate,isopropanol,water and Al of 0.15:0.075:0.5:25:1,reaction temperature of 95 ℃ and reaction time of 0.5 h,the corrosion inhibiting efficiency and the coater gloss reach 99.3% and 88.3Gs,respectively.Furthermore,the waterborne aluminum pigments were analyzed by scanning electron microscopy,laser particle size analysis and Fourier transform infrared spectrum,which reveal that the flaky aluminum powders are successfully coated with polyacrylic acid.
