Example Embodiment
[0023] Example one
[0024] Add 100Kg of bis(2,3-epoxycyclopentyl) ether and 50Kg of bis(4-amino-3-methylcyclohexyl)methane into the reactor, stir at 120°C for 30 minutes; then add 40Kg of adipic acid (3,4-epoxy-6-methylcyclohexyl carboxylic acid), stir for 1 hour, then add 10Kg of glass beads and 25Kg of methacrylic acid, stir at 130°C for 20 minutes to obtain an epoxy composition; add 100Kg of dinaphthyl Add carbonate, 60Kg dicyclohexyl carbonate, 10Kg mica to methyl ethyl ketone, stir at 50°C for 20 minutes, then add 18Kg dihydroxy polydiethylsiloxane, 25Kg amine phosphate, 20KgN-methylol acrylamide, under ventilation Stir at 110°C for 10 minutes to obtain a carbonate composition; heat and mix 60Kg of epoxy composition with 180Kg of carbonate composition, then add to the mold, and heat and press at 100°C and 1MPa for 3 minutes to obtain an elastic material. After testing, the flame retardant is UL94V1; the elongation at break is 54%; the bending elasticity is 210MPa.
