Donghua University develops high temperature resistant composite matrix resin

Donghua University has developed a high temperature resistant composite matrix resin and its preparation method. The components include: maleimide polyimide powder, diallyl compound and bismaleimide resin powder; The preparation method comprises the following steps: mixing 1,4-bis(2,4-diaminophenoxy)benzene with a strong polar aprotic organic solvent, adding a raw material such as maleic anhydride to prepare a resin solution; then adding a dehydrating agent, a catalyst and The powder is precipitated to precipitate a solid powder; the maleimide-based polyimide powder, the diallyl compound, and the bismaleimide resin powder are put into a reaction vessel for melt polymerization and in an organic solvent Dissolved, that is, too. The high-temperature resistant composite matrix resin can be applied not only to a glass fiber reinforced composite material but also to a high-performance fiber reinforced advanced composite material such as carbon fiber and aramid fiber; and the process is simple, the cost is low, the environment is friendly, and can be used universally. The preparation process is completed in the equipment and is suitable for industrial production.
