摘要
本文主要针对传统聚丙烯酰胺微球耐温性能较差,高温下容易降解,难以适应苛刻的地层条件等缺点,在丙烯酰胺单体(AM)的基础上,创新性的加入实验室自制的水溶性酚醛树脂(PF),以N-N'-亚甲基双丙烯酰胺(Bis-A)为交联剂,过硫酸钾(KPS)为引发剂,采用反相悬浮法,制得微米级的交联聚合物微球。利用光学显微镜、扫描电镜、激光粒度仪、红外光谱分析仪(IR)观测微球的形貌、大小和结构组成,利用水溶液实验评价微球的耐温性能。实验结果表明,合成的聚合物微球中发生了PF中的羟甲基与AM中的酰胺基的交联反应;制得的微球成球性好,粒径范围为10~75μm,并且微球溶胀性能良好,水溶液中膨胀大约10倍;耐温实验表明,在140℃去离子水中能稳定存在30天左右,因此具有较好的热稳定性。
To solve the problem of the unfavorable temperature resistance and inadaptability to harsh formation conditions of the conventional Polyacrylamide Microspheres,Water Soluble Phenolic Resin(PF) is innovatively added during the synthesis process.N,N'-methylene-bis-(acrylamide) and potassium persulfate are taken as cross-linking agent and initiator respectively.Inverse suspension polymerization is utilized to obtain micron-grade polymer microspheres.The shape,size and structure of the microspheres were investigated by microscope,scanning electron microscope(SEM),laser particle size analyzer and IR.Temperature resistance of the microspheres was evaluated in aqueous solution.The results show that the original shape of the microspheres was typically spherical with the diameter range of 10~75 μm,and the volume of the swollen microspheres was 10 times larger than that of the original microspheres.Meanwhile,the microspheres can stably exist for about 30 days in deionized water under the condition of 140 ℃,which indicates that the microspheres have preferable temperature resistance.
