摘要
该文利用Minitab软件中的Plackett-Burman、Box-Benhnken和响应优化器设计和优化苯丙乳液合成实验,综合分析了影响苯丙乳液合成的因素,获得了较优的合成方案。首先利用Plackett-Burman设计实验方案并分析实验数据,筛选出影响苯丙乳液合成的3个主要因素:乳化剂用量、功能单体用量、引发剂用量。然后利用Box-Benhnken设计实验,用响应优化器优化实验结果得到较优的合成方案:苯乙烯和丙烯酸酯单体的质量配比为1∶1,转速220 r/min,反应温度75℃,乳化剂、功能单体和引发剂质量分数分别为1.04%,1.85%,0.47%。用合成的苯丙乳液与阴离子淀粉配制成表面施胶液施胶复印纸原纸,施胶纸张平均Cobb值达22.6 g/m2。实验结果表明,与其他合成方案相比,用Minitab优化方案合成的苯丙乳液施胶效果最好,其各项性能的预测值与实验平均值拟合度达98.26%～98.72%。
By using the Plackett-Burman design,the Box-Benhnken design and the response optimizer in the Minitab software to design and optimize the styrene-acrylate emulsion synthesis experiments,the influence factors on the synthesis are analyzed and the optimal synthesis scheme is obtained.The Plackett-Burman is applied to conduct the experiment.By analyzing the experimental data,the dosages of emulsifiers,initiators and functional monomers are obtained as the three main influence factors on the styrene-acrylate copolymer emulsion performance.The Box-Benhnken is used to design the experiment and the experimental data are optimized by the response optimizer to get the optimal synthesis scheme：the monomer mass ratio of styrene to butyl acrylic is 1∶1,the rotate speed is 220 r/min,the reaction temperature is 75 ℃,and the mass percentages of emulsifiers,functional monomers and initiators are 1.04%,1.85% and 0.47% respectively.The synthetized styrene-acrylate emulsion is mixed with the anionic starch as surface sizing agent to size the copy base pape,and the average Cobb value of sized paper is 22.6 g/m2.The experimental results show that styrene-acrylate copolymer emulsion synthesized under the Minitab optimized scheme gives the best sizing efficiency,and the agreement of the average experimental results and the predicted value for performances reaches 98.26%~98.72%.
