摘要

系统研究了样品厚度和饱和压力对聚苯乙烯(PS)和聚甲基丙烯酸甲酯(PMMA)发泡行为和发泡窗口的影响规律. 首先，研究了样品厚度和饱和压力对PS和PMMA对CO

吸附行为的影响；然后，利用釜压发泡法制备了PS和PMMA发泡材料，并研究了厚度和饱和压力对泡孔结构和膨胀倍率的影响；最后，根据泡孔结构和膨胀倍率确定了发泡温度的上下限，界定出了发泡温度窗口，并探讨了厚度和饱和压力对发泡温度窗口的影响规律. 结果表明，饱和压力增大，PS和PMMA对CO

的饱和吸附量均增大，相同饱和压力下，PMMA的饱和吸附量更大；在较小的饱和压力下，厚度越大，PMMA对CO

的吸附越慢. 厚度和饱和压力显著影响PS和PMMA的泡孔结构和膨胀倍率，饱和压力增大，CO

的塑化作用增强，厚度对PMMA的发泡影响更显著. 饱和压力增大，PS和PMMA的发泡温度上下限均向低温方向移动，PMMA对厚度和饱和压力的变化更敏感，PMMA比PS的发泡温度窗口更窄.

Abstract

In the present work

the effect of sample thickness and saturation pressure on foaming behavior and foaming window of polystyrene (PS) and poly(methyl methacrylate) (PMMA) was systematically studied. First

the effect of sample thickness and saturation pressure on sorption of CO

of PS and PMMA was studied; Then

PS and PMMA foams were prepared

via

a batch foaming process

and the effect of sample thickness and saturation pressure on cell structure and expansion ratio was studied; Last

the upper and the lower limits of the foaming temperature were defined based on the cell structure and the expansion ratio

and hence the foaming temperature window was obtained

and the effect of sample thickness and saturation pressure on foaming temperature window was studied. The results show that the higher the saturation pressure was

and the higher the sorption of CO

of PS and PMMA was. The sorption of CO

in PMMA was larger than in PS under the same saturation pressure. Under a lower saturation pressure

PMMA with a larger thickness showed slower sorption of CO

. The sample thickness and saturation pressure significantly affected the cell structur

e and the expansion ratio. A higher saturation pressure showed a more obvious plasticization effect of CO

. The sample thickness showed a more significant effect on foaming of PMMA. A higher saturation pressure made the upper and the lower foaming temperature limits move to the lower temperature direction. PMMA was more sensitive to the change in thickness and saturation pressure

and had much narrower foaming temperature window than PS did.
