【摘要】 以苯乙烯和丙烯酸酯为主体,加入功能单体,通过乳液聚合制成环保型、成本低廉的水乳性表面施胶剂,并用FT-IR测试方法对其结构进行了表征。通过定时跟踪固含量,研究了聚合工艺、聚合条件对聚合产品的影响。在两步聚合法、搅拌速度180r/min、反应温度75℃、反应时间2h、保温时间2h的工艺条件下,单体的转化率在85%以上。更多还原

【Abstract】 An environmentally friendly and low cost surface sizing agent was prepared by using styrene and acrylate as the main elements of emulsion polymerization,adding functional monomer.The structure was characterized by FT-IR.Through follow-up the solid content,it is researched that how polymerization conditions affect the polymerization products,and the styrene-acrylic emulsion composing process conditions were as follow:a two-step polymerization,the stirring speed is 180r/min,the reaction temperature is 75℃,reaction time is 2h, holding time is above 2h.In this case,the monomer conversion rate is more than 85%.更多还原
