[0027] Described modified epoxy resin, preparation method comprises the steps:
[0028] (1) Dissolve 2.13g of 2,4-dihydroxym-phenylenediamine hydrochloride and 1mL of triethylamine in 25mL of N-methylpyrrolidone, add 3.1g of diphenyl ether tetracarboxylic dianhydride, 10mL toluene and 1.0 g of glacial acetic acid, and then heated to 180 ° C for 5 hours, after the reaction was completed, precipitated in methanol, filtered, and vacuum-dried to obtain a hydroxyl-containing polyimide.
[0029] (2) Bisphenol A type epoxy resin, polyimide obtained in step (1), norbornene diacid anhydride, 2,4,6-tri(di Mix methylaminomethyl) phenol and stir evenly while heating. The heating program is to heat at 120°C for 1 hour, and then continue to heat up to 150°C for 3 hours to obtain the product.
[0030] The first diluent is a monoepoxy glycidyl ether reactive diluent and / or a diepoxy glycidyl ether reactive diluent.
[0031] The synthetic method of described first diluent comprises the steps...
