1. a preparation method for Phthalazinone polyarylether High performance plastic resin base copper-clad plate, is characterized in that, the preparation method of described Phthalazinone polyarylether High performance plastic resin base copper-clad plate comprises the following steps:

  • (1) surface of glass-fiber-fabric is first processed, be that 1.5% high temperature resistant coupling agent joins N by the mass ratio with solvent, in N-dimethylacetylamide (DMAc) solvent, at room temperature and under 300rpm rotating speed mix 10min, obtain the surface processing solution of glass-fiber-fabric;

    (2) glass-fiber-fabric to be immersed in the obtained surface processing solution of step (1) 5 minutes;

    Take out natural air drying after 30 minutes, dry 10 minutes at 50 DEG C in normal pressure baking oven, dry 10 minutes at 100 DEG C, dry 30 minutes at 160 DEG C, obtain surface-treated glass-fiber-fabric;

    (3) select Phthalazinone polyethers nitrile ketone PPENK/ inbred group breeding PPESK blending resin to be raw material, its ratio is;

    PPENK/PPESK=8;

    2;

    30 parts of blending resins are dissolved in 100 parts with volume ratio DMAc;

    DMF;

    in the mixed solvent of toluene=1.2;

    1;

    1, stirred at ambient temperature is after 30 minutes, and solution is homogeneous, obtained presoak;

    (4) presoak that step (3) prepares is poured in dipping tank, the glass-fiber-fabric that step (2) processed is immersed in dipping tank, flood 5 minutes, take out the glass-fiber-fabric of kiss-coating, dry 10 minutes at 90-100 DEG C, dry 10 minutes at 100-120 DEG C, dry 10 minutes at 120-140 DEG C, dry 20 minutes at 140-170 DEG C, dry 10 minutes at 2000-230 DEG C;

    Repeat this step until the content of resin is 50% in glass-fiber-fabric;

    (5) presoak in step (3) is added 0.5% high temperature resistant coupling agent, be coated in copper foil surface after mixing, brushing number of times is 1 time;

    According to the drying process of step (2), dry gluing Copper Foil;

    (6) preimpregnation glass-fiber-fabric prepared by step (4) is cut on request the bonding sheet of given size, according to the thickness requirement of the copper-clad plate of regulation, several bonding sheets are neatly stacked together, and lower surface respectively puts gluing Copper Foil obtained in a step (5) thereon, 350 DEG C are heated to the firing rate of 10 DEG C/min, briquetting pressure is 30atm, molding time is 20 minutes, then room temperature is cooled at this pressure, obtained PPENK/PPESK resin-based high performance copper clad laminate.
