摘　　要：采用新的合成路线和方法,以尿素和马来酸酐为主要原料,制备了无磷缓蚀阻垢剂聚天冬氨酸(PASP)。在45℃、Ca2+浓度为200 mg.L-1条件下,只需加本工艺合成的PASP 4 mg/kg,阻垢效果就可达到93%并持效20 h以上。Poly - aspartic acid was prepared from maleie anhydride and urea, and its scale inhibition performance was studied, The scale inhibition effect was reached 93% and maintained 20 h when 200 mg/L of Ca^2＋ and 4 mg/kg of PASP were used.

关 键 词：聚天冬氨酸 阻垢缓蚀剂 无磷水处理剂 循环冷却水
