摘要：NOVELTY - This invention claims a heatproof pair-horse/epoxy resin and its operating method; the operating method comprises the follows: (1), chain extender is exerted in pair-maleimide, react for 15min to 150min at 130 centigrade to 180 centigrade then exert solvent to obtain the pair-maleimide prepolymer; (2), mix the chain extension pair-maleimide in the step (1) with the epoxy resin at 120 centigrade to 180 centigrade to obtain pair-horse/epoxy resin; solidify the pair-horse/epoxy resin in the step (2) at 130centigrade to 180 centigrade for 2h to 8h to obtain the heatproof pair-horse/epoxy resin condensate. The pair-horse/epoxy resin operated by this method of this invention improves the cohensive strength of the resin, resists to effect of heat, reduces remains solidify stress and makes the operation be simple; the cost is low and it is convenient to industry produce.
