P(AM-AA)微球的合成及粒径影响因素
Synthesis of P(AM-AA) microspheres and factors affecting particle size
随着造孔剂法制备多孔陶瓷技术的进步,造孔剂的种类成为限制该行业发展的主要因素之一,为了解决这一问题,合成了一种粒径和吸水倍率适中的有机造孔剂。以丙烯酰胺(AM)和经氨水中和至一定中和度的丙烯酸(AA)为共聚单体,在油相正己烷中以失水山梨醇单油酸酯(Span 80)为分散剂、过硫酸铵(APS)为引发剂、N,N'-亚甲基双丙烯酰胺(MBA)为交联剂,采用反相悬浮聚合法制备了P(AM-AA)微球。研究结果表明,在优选条件下,合成了吸水倍率约为17 g/g、吸水后中值粒径约45 μm的PAM交联微球,表现出很好的吸水膨胀性,可用作某些特定领域的造孔剂。
With the advancement of pore-forming agent (PFA) methods for preparing porous ceramics,the variety of available PFA has emerged as one of the key factors limiting the development of this industry.To address this challenge,a new organic pore-forming agent with moderate particle size and water absorption capacity was synthesized.The agent was produced through inverse suspension polymerization,using acrylamide (AM) and partially neutralized acrylic acid (AA) as copolymer monomers in N-hexane oil phase.The process employed sorbitan monooleate (Span 80) as dispersant,ammonium persulfate (APS) as initiator,and N,N'-methylenebisacrylamide (MBA) as crosslinker.The study results indicate that under optimized conditions,PAM cross-linked microspheres with water absorption capacity of approximately 17 g/g and median particle size of about 45 μm after swelling were successfully synthesized.These microspheres exhibited excellent water absorption and swelling characteristics,making them suitable for use as pore-forming agents in specific applications.
