1. the preparation method of a fire resistant polyimide glass cloth laminated board comprises the steps:

  • (1) under the room temperature, with mol ratio be 1;

    21,4-two (2, the 4-diamino phenoxy) benzene and maleic anhydride add in the strong polar non-proton organic solvent, stirring reaction added aromatic diamine monomer after 1 hour under the room temperature, after stirring and dissolving is complete, add aromatic dicarboxylic anhydride, stirring reaction is 3 hours under the room temperature, adds initator, stirring and dissolving, obtain the thick resin solution of homogeneous phase transparent, i.e. the A component;

    Wherein, 1, the mol ratio of two (2, the 4-diamino phenoxy) benzene of 4-and aromatic diamine monomer is 1;

    5-8;

    The mole dosage of aromatic dicarboxylic anhydride is 1, the 98%-100% of the molal quantity sum of two (2, the 4-diamino phenoxy) benzene of 4-and aromatic diamine monomer;

    The mass ratio of initator and maleic anhydride is 1;

    80-100;

    The solid masses percentage composition of resin solution is 15%-20%;

    (2) with mol ratio be 1;

    41,4-two (2, the 4-diamino phenoxy) benzene and maleic anhydride add in the strong polar non-proton organic solvent, stirring reaction is after 2 hours under the room temperature, obtain the resin solution of homogeneous phase transparent, be the B component, wherein, the solid masses percentage composition of resin solution is 30%-40%;

    When (3) using, under the room temperature with A, B component by mass ratio 1;

    2-4 mixes, must the polyimide precursor resin solution, use the glass cloth impregnating resin solution, the preliminary drying semi-solid preparation gets prepreg, enters the heat cure of high-temperature high-pressure machine after stacked, obtains the fire resistant polyimide glass cloth laminated board.
