1. , a kind of curable halogen-containing composition epoxy resin, it comprises:

  • (a) at least a Resins, epoxy;

    (b) at least a stiffening agent;

    Wherein stiffening agent is that the compound of phenolic hydroxy group functionality maybe can be by adding the compound of thermogenesis phenolic hydroxyl group functionality;

    (c) the nitrogenous catalyzer of catalytic amount;

    With(d) can reduce the non-nitrogenous catalyzer auxiliary compound of nitrogenous catalyst concn;

    Wherein, at least a or multiple of said components (a)-(d) is halogenated or halogen-containing;

    If perhaps said components does not all have halogenation, then wherein resin combination comprises (e) halogenation or halogen-containing flame retardant compound;

    Be characterised in that the stroke cure gelation time of resin combination maintains 90 seconds to 600 seconds when when measuring down for 170 ℃

    ;

    And make the gained cured product that forms by the cure curable composition epoxy resin contain the following character that is in admirable proportion;

    (1) greater than 130 ℃

    Tg;

    (2) greater than 320 ℃

    Td;

    (3) greater than 1 minute T288;

    (4) greater than the bounding force of 10N/cm to copper;

    With(5) the UL94 flame retardant resistance of V-1 grading at least.
