| 摘 要： | 采用月桂酸和钛酸四丁酯对三聚磷酸二氢铝进行包覆改性。采用正交试验得到的最优反应条件为:钛酸四丁酯与三聚磷酸铝质量比0.15,钛酸四丁酯溶液质量分数10%,反应温度25℃,搅拌速率200 r/min,反应时间4 h。相比三聚磷酸二氢铝,得到月桂酸-Ti4+包覆三聚磷酸二氢铝对二甲苯、松节油和椰子油的接触角增大,说明其铺展程度及润湿效果得到了提升。用其制成的醇酸、环氧和聚酯涂料均有很好的贮存稳定性,用其制得的环氧底漆的耐盐雾性比用未改性的三聚磷酸二氢铝时更好。

| Abstract: | Aluminum dihydrogen tripolyphosphate was modified by lauric acid and tetrabutyl titanate.The optimal reaction conditions were determined by orthogonal test as follows:mass ratio of tetrabutyl titanate to aluminum tripolyphosphate 0.15,mass fraction of tetrabutyl titanate solution 10%,reaction temperature 25℃,stirring rate 200 r/min,and reaction time 4 h.Compared with the unmodified aluminum dihydrogen tripolyphosphate,the lauric acid?Ti4+clad aluminum dihydrogen tripolyphosphate had a larger contact angle to xylene,turpentine,and coconut oil,indicating that its spreading degree and wetting effectiveness were improved.The alkyd paint,epoxy paint,and polyester paint prepared with the lauric acid?Ti4+clad aluminum dihydrogen tripolyphosphate had good storage stability,and the epoxy primer made with it had better salt spray resistance than that prepared with the unmodified aluminum dihydrogen tripolyphosphate. |
