Ionic liquid catalyzed cured pentaerythritol acrolein resin and preparation method thereof

The invention discloses an ionic liquid catalyzed cured pentaerythritol acrolein resin and a preparation method thereof. According to the ionic liquid catalyzed cured pentaerythritol acrolein resin, an ionic liquid catalytic curing agent is applied to curing pentaerythritol acrolein resin, so that the cured pentaerythritol acrolein resin is good in shaping performance and capable of meeting requirements on appearance; the pentaerythritol acrolein resin is preprocessed in vacuum to remove low-molecular materials and improve the content of the effective constituents of raw materials; a resin system processed and mixed in vacuum can ensure good shaping and filling performance of the cured pentaerythritol acrolein resin and avoid defects such as pores and further can increase the density of the cured pentaerythritol acrolein resin. The specific ionic liquid catalyzed cured pentaerythritol acrolein resin can avoid application of high-toxicity catalytic curing agents, and meanwhile, the cured pentaerythritol acrole
