摘　　要：将腈纶厂下脚料聚丙烯腈用 Ｋ Ｏ Ｈ 水解，用三甲胺和甲醛进行阳离子化，再用过氧化氢氧化，制得了阳离子度为９ ．３ ％ 的降粘降滤失剂 Ｐ Ｘ１ ，在加量为 ０ ．２ ％ 的情况下可使膨润土基浆的漏斗粘度降低６３ ．３ ％ ，切力降低８６ ．５ ％ ， Ａ Ｐ Ｉ 滤失量降低３７ ．５ ％ ，抗盐抗污染性能良好，页岩回收率明显高于水解聚丙烯腈钠。对其作用机理作了简要分析。Viscosity/filtrate loss reducer PX 1 of cationization degree 9.3% is prepared through hydrolysis of polyacrylonitrile (PAN)(waste polymer from fiber spinning) by KOH, cationization of partially hydrolyzed PAN by trimethylamine and formaldehyde and oxidation of cationic product by H 2O 2. PX 1 in amount of 0.2% decreases funnel viscosity of the basic bentonite mud by 63.3%, yield stress by 86.5%, API filtrate loss—by 37.5%, respectively, and is tolerent to NaCl and Ca 2+ . PX 1 is much more inhibitory in shale recovery tests than Na HPAN does. The functions of PX 1 in viscosity and filtrate loss reduction are discussed briefly.
