Embodiment 1

[0015] Under stirring conditions, add 38 grams of bisphenol A, 100 grams of triglycidyl amine cyanurate, 5 grams of E-51 resin, 1 gram of triphenyl phosphine, and 10 grams of dicyandiamide into the reaction kettle. Under the condition of ℃, react for 1 hour under stirring to obtain the molten epoxy resin matrix, pour the molten epoxy resin matrix into the mold, and then put it in the drying box, cure at 150℃ for 1 hour, and get it after cooling 154 grams of cured nitrogen-containing epoxy resin.

Embodiment 2

[0017] Under stirring conditions, add 228 grams of bisphenol A, 100 grams of cyanuric acid triglycidylamine, 10 grams of E-51 resin, 5 grams of triphenyl phosphine, and 20 grams of dicyandiamide into the reactor, and the temperature is raised to 150 ℃, react under stirring for 1 hour to obtain a molten epoxy resin matrix, pour the molten epoxy resin matrix into a mold, and then put it in a drying oven, and solidify at a temperature of 150°C for 1 hour. After cooling, the nitrogen-containing matrix is ​​obtained. 363 grams of cured epoxy resin.

Embodiment 3

[0019] Under stirring conditions, add 90 grams of bisphenol A, 100 grams of cyanuric acid triglycidylamine, 10 grams of E-51 resin, 5 grams of triphenyl phosphine, and 20 grams of dicyandiamide into the reactor, and the temperature is increased to 120 ℃, react with stirring for 3 hours to obtain a molten epoxy resin matrix, pour the molten epoxy resin matrix into a mold, and then put it in a drying box, and solidify at a temperature of 180°C for 5 hours. After cooling, a nitrogen-containing matrix is ​​obtained. 225 grams of cured epoxy resin.

Abstract

The invention discloses a method for preparing a nitrogen-containing epoxy resin cured material, which comprises the following steps: (1) under a stirring condition, adding E-51 epoxy resin, bisphenol A, triglycidyl isocyanurate, acetaldehyde and a curing agent into a reactor to perform a reaction to obtain a molten epoxy resin substrate; and (2) pouring molten epoxy resin into a forming mold to perform a heating curing reaction and cooling to obtain the nitrogen-containing epoxy resin cured material. The method avoids using an organic solvent and radically solves a problem of solvent residue in the epoxy cured material; common E-51 epoxy resin is introduced into the cured material, so the viscosity of the epoxy substrate is lowered and operation is facilitated; and a triazine ring in the triglycidyl isocyanurate is introduced into the chain of the epoxy resin, and a flame-retarding effect is achieved.

Description

Technical field [0001] The invention relates to a preparation method of a nitrogen-containing epoxy resin cured product. Background technique [0002] Many countries or regions in the world (especially Europe) have formulated and promulgated many regulations on restricting or banning halogen-containing flame-retardant substrate materials, and halogen-based flame-retardant polymer materials have not obtained the green environmental protection mark in Europe. Some famous electronic product manufacturers in the world have begun to use halogen-free substrates. According to the recent analysis of relevant world organizations, from 2005 to 2010, the implementation of various laws and regulations concerning the prohibition of hazardous halogen-containing materials, including the "Two European Directives" (WEEE&RoHS, effective on July 1, 2006), prompted the world The amount of halogen-free substrate materials rapidly increased to 50% to 80% of the total amount. In response to EU direct...
