    摘要:

    利用离子液体1-丁基-3-甲基咪唑六氟磷酸盐([BMIM][PF6])作为季戊四醇丙烯醛树脂(123树脂)的增塑剂, 研究了[BMIM][PF6]含量为0~10%条件下其对123树脂增塑性能的影响。分别采用万能试验机和动态力学分析仪(DMA)研究了[BMIM][PF6]对123树脂固化物综合力学性能的影响。结果表明, BMIM][PF6]能提高123树脂预聚体的流动性, 效果优于邻苯二甲酸二乙酯(DEP), 加入10%的[BMIM][PF6]能将123树脂预聚体50 ℃粘度降至185 mPa·s。[BMIM][PF6]含量越多123树脂固化物的断裂延伸率越大、拉伸强度越小, 加入10%的[BMIM][PF6]的123树脂固化物的断裂延伸率和拉伸强度分别为14.2%和38.2 MPa。123树脂固化物的玻璃化温度随[BMIM][PF6]含量增加而降低, 韧性随[BMIM][PF6]含量增加而增加。

    Abstract:

    Ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]) was used as a plasticizer of acrolein-pentaerythritol resin (123 resin). The effect of [BMIM][PF6] content under the condition of 0~10% on the plasticizing properties of 123 resin was studied. The comprehensive mechanical properties of cured 123 resin were studied by an universal testing machine and a dynamic mechanical analyzer (DMA) respectively.Results show that [BMIM][PF6] can effectively improve the flowability of prepolymer of 123 resin, the effect is better than that of diethyl phthalate (DEP) and addition of 10% [BMIM][PF6] can make the viscosity of 123 resin prepolymer at 50 ℃ reduce to 185 mPa·s. The more the [BMIM][PF6] content, the greater the elongation at break and the lower the tensile strength of 123 resin cured products, and the elongation at break and tensile strength of 123 resin containing 10% [BMIM][PF6] are 14.2% and 38.2 MPa, respectively. The glass transition temperature decreases and tenacity increases of 123 resin cured products with the increasing of [BMIM][PF6] content in 123 resin.
