Embodiment 1

[0011] By weight, melt copolymerize 10 parts of dicyclopentadiene type cyanate ester resin and 10 parts of glycidyl ether epoxy resin (E51) at 80°C for 40 minutes; then add 90 parts of dicyclopentadiene type cyanate at 80°C The ester is evenly mixed with it to obtain the epoxy resin E51 and the dicyclopentadiene type cyanate resin copolymer.

Embodiment 2

[0013] By weight, melt copolymerize 1 part of dicyclopentadiene type cyanate resin and 30 parts of glycidylamine epoxy resin (part A-80) at 120°C for 30 minutes; then add 99 parts of dicyclopentadiene at 120°C Type cyanate and 170 parts of epoxy resin E51 are mixed with it, and melted uniformly in an oil bath to obtain epoxy resin A part-80 and dicyclopentadiene type cyanate resin copolymer.

Embodiment 3

[0015] By weight, melt copolymerize 30 parts of dicyclopentadiene type cyanate resin and 1 part of glycidyl ether epoxy resin E44 at 150°C for 25 minutes; then add 70 parts of dicyclopentadiene type cyanate ester and 199 parts of epoxy resin E44 were uniformly mixed with it to obtain a copolymer of epoxy resin E44 and dicyclopentadiene type cyanate resin.

Abstract

The disclosed copolymer is fused and copolymerized by the epoxy resin of 100 weight shares and 1-200 thermosetting cyanate resin, has high ductility and strength and super dielectric property, and thermostable and heat-wet proof. The fractional fusion and copolymerization method has no pollution and wide application.

Description

technical field [0001] The invention relates to a preparation method of epoxy resin and thermosetting cyanate resin copolymer. Background technique [0002] Cyanate resin has excellent dielectric properties, high heat resistance, good comprehensive mechanical properties and extremely low water absorption. It is a functional material and structural material with great potential in the aviation field since the 20th century. Among the cyanate resins, the dicyclopentadiene cyanate resin has better mechanical properties, moisture resistance and electrical properties than the commonly used bisphenol A cyanate resin due to its unique molecular structure. However, the cured product of dicyclopentadiene cyanate is relatively brittle, and it needs to be toughened and modified to meet the requirements of more occasions. Dicyclopentadiene cyanate resin is toughened and modified by epoxy resin. Sex work has not been reported. Contents of the invention [0003] In order to overcome th...
