Technical Field

[0001] The utility model relates to the technical field of bismaleimide purification, in particular to a bismaleimide purification machine with a quantitative feeding function. Background Art

[0002] Bismaleimide is another type of resin system derived from the polyimide resin system. It is a bifunctional compound with maleimide as the active end group. It has similar fluidity and moldability to epoxy resin and can be processed and molded using the same general methods as epoxy resin, overcoming the disadvantage of relatively low heat resistance of epoxy resin. After the production of bismaleimide is completed, it needs to be purified. Generally, a heating plate is installed on the wall of the purification tank to remove the moisture contained in the bismaleimide.
