| 摘 要： | 采用同步法合成了聚氨酯/环氧树脂互穿网络聚合物(PU/EP IPN)硬质泡沫,对机械性能进行了研究。结果表明,与纯聚氨酯硬质泡沫相比,PU/EP IPN硬质泡沫的压缩强度和弯曲强度明显提高,在PU/EP IPN硬质泡沫中,随环氧树脂含量增加,PU/EP IPN硬质泡沫压缩强度和弯曲强度随之增大,当E-39D质量分数增加到24.2%时,PU/EP IPN硬质泡沫压缩强度和弯曲强度出现最大值;PU/EP IPN硬质泡沫机械强度随材料密度的增大而增加;随着环氧树脂中环氧值的增加,PU/EP IPN硬质泡沫的压缩强度、弯曲强度和拉伸强度均呈逐渐升高的趋势。

| Abstract: | A series of rigid interpenetrating polymer network(IPN) foams,based on polyurethane(PU) and epoxy resin(EP),were prepared by a simultaneous polymerization technique.The mechanical properties of the PU/EP IPN were reseurched.The results show that higher compressive strength and flexile strength were observed with the IPN foams in comparison to the corresponding polyurethane rigid foams.In the rigid PU/EP IPN foams,the compressive strength and flexile strength increased with the increment of EP content,and gained the highest value when E-39D content 24.2%;and the mechanical strength increased with the increment of material density;Furthermore,the compressive strength,flexile strength and tensile strength all increased with the increment of epoxy value of EP. |
