摘要
介绍了以三氯化磷 (PT)、丙酮 (AC)和冰醋酸 (HA)为原料合成异丙烯膦酸 (IPPA)单体的方法 ,然后用该单体和丙烯酸 (AA)共聚得到AA IPPA聚合物。讨论了聚合条件 (如引发剂用量、温度、聚合时间 ,原料配比等 )对聚合物性能的影响。根据钻井泥浆降粘剂分子结构的特点及其作用机理 ,把该聚合物用作钻井泥浆降粘剂。性能评价试验结果表明 ,AA IPPA二元聚合物有很好的降粘效果 ,抗温能力较强 ,与丙烯酸均聚物相比 。
A method that Isopropenyl phosponic acid (IPPA) monomer is synthesized by acetone (AC), phosphorus trichloride (PT) and glacial acetic acid has been introduced. Then AA*.IPPA copolymer has been synthesized by isopropenyl phosphonic acid and acrylic acid (AA). The influence of synthetic conditions on the performance of the copolymer has been discussed. Based on the characteristics of molecular structure and reaction mechanism of thinner as drilling fluids, AA*.IPPA can be used as mud thinner. Laboratory experiment results show that the thinner possesses excellent thinning property and good temperature resistance, and the ability of salt and calcium resistance is better than polymer of acrylic acid.
