摘　　要：用单因素法分析蒙脱土和酚醛树脂混合溶液的固化情况,结果表明蒙脱土分散浓度增加,混合溶液固化时间增长;酚醛树脂浓度和固化温度加大,固化时间缩短,其中温度是影响固化效果较为明显的因素;不加固化剂时固化效果更好。The paper analyzed the gelation status of phenol-formaldehyde resin/montmorillonite mixed solution through unitary factor. The results showed that temperature is an obvious factor of affecting gelation time. The gelation time will protract when the dispersive thickness of montmorillonite augments, but it will shorten when phenol-formaldehyde resin thickness and gelation temperature increase. The coagulation effect is better when solidifying reagent is not used.
