摘要： 对有机硅表面活性剂、发泡剂、稳泡剂等5种试剂运用正交实验法开展泡沫性能筛选实验。采用自主设计的机械臂振荡装置测定该复配体系的发泡倍数和25%析液时间。采用自主设计的泡沫耐热性测定装置测定该复配体系的热稳定性时间。正交实验设计为5因素4水平。实验结果表明：有机硅表面活性剂、发泡剂和稳泡剂产生了较好的协同作用，复配体系的25%析液时间较单一有机硅表面活性剂提高了10倍以上。对该复配体系的发泡倍数、25%析液时间、泡沫热稳定时间综合分析发现：当Si-4903、APG、BS-12、黄原胶、6501质量浓度比为10∶20∶10∶1∶1时泡沫性能最好。

Abstract: Five kinds of reagents, such as silicone surfactant, foaming agent and foam stabilizer and etc., were screened by orthogonal experiment. The foaming ratio, 25% liquid separation time of the compound system were tested by self-designed oscillating device of mechanical arm.The thermal stability time of the compound system was determined by the self-designed foam heat resistance measurement device.The orthogonal experiment was designedas 5 factors and 4 levels. The results showed that the silicone surfactant, foaming agent and foam stabilizer have a good synergistic effect,and the 25% liquid separation time of the compounding system is more than 10 times higher than that of the single organosilicone surfactant. The comprehensive analysis of foaming ratio, 25% liquid separation time and foam thermal stability time of the system showed that when the concentration ratio of Si-4903, APG, BS-12, xanthan gum and 6501 is 10∶20∶10∶1∶1, the foam performance is the best.
