1. a preparation method for Cardanol Modified PF Resin, is characterized in that, described method steps is as follows:

  • By the phenol melted in advance, load with in the reaction vessel stirred, then add formaldehyde;

    Drip the catalyzer of 1/2 amount after stirring, be then warming up to 60 DEG C, become after muddiness until system, add cardanol, and drip the catalyzer of residue 1/2 amount, after catalyzer dropwises, be warming up to 65 DEG C, insulation reaction 1h, is then warming up to 70 DEG C of reaction 1.5h, stops heating;

    By reacted suspension liquid in Rotary Evaporators, carry out underpressure distillation, until when evaporated condensation water flows in receiving flask, stop underpressure distillation;

    Treat that temperature is cooled to 50 DEG C, then add solvent, regulate solid content to be 15% ~ 75%, namely obtain described Cardanol Modified PF Resin.Wherein, the mol ratio of described formaldehyde and aldehydes matter is 1.2;

    1, and described aldehydes matter is phenol and cardanol, and the mol ratio of phenol and cardanol is 1;

    9 ~ 9;

    1;

    Every 1.2mol formaldehyde need add catalyzer 30g.
