摘　　要：对比了4种硫酸钡对水性丙烯酸聚氨酯涂料的光泽、贮存稳定性、耐化学品等性能的影响,从原理上分析了硫酸钡效果不同的原因。结果表明,沉淀硫酸钡MECRO对水性丙烯酸聚氨酯涂料的光泽影响最小,并具有优良的耐化学品性,以及稳定的贮存性能。Four kinds of barium sulfate were used in waterborne acrylic polyurethane coatings to investigate the gloss,storage stability,chemical resistance,etc.The reason for the different effects of barium sulfate was also discussed.The results show that MECRO-precipitated barium sulfate has the least effect on the gloss of waterborne acrylic polyurethane coatings,and possesses excellent chemical resistance and storage stability.
