Embodiment 1
[0027] 1. Weigh 60g of liquid E-51 epoxy resin into a clean beaker, then add 30g of diethylene glycol butyl ether solution into it, place it on a digital constant temperature heating platform, set the temperature at 80°C, and at the same time, use 800rpm Stir at a rotating speed for 10 minutes to obtain a uniform resin solution.
[0028] 2. Slowly add 6g of fumed silica modifier and 30g of diethylene glycol butyl ether solution to the resin solution, raise the temperature of the heating table to 110°C, adjust the stirring speed to 1000rpm, and stir for 30min to obtain the modified E-51 ring oxygen resin.
Embodiment 2
[0030] 1. Weigh 60g of liquid Nanya NPEF-170 epoxy resin into a clean beaker, then add 15g of methyl nylon acid and 15g of diethylene glycol butyl ether solution into it, place it on a digital constant temperature heating platform, and set the temperature to 95° C., while stirring at a speed of 900 rpm for 10 minutes to obtain a uniform resin solution.
[0031] 2. Slowly add 7.5g of fumed silica modifier, 15g of methyl nylon acid and 15g of diethylene glycol butyl ether to the resin solution, raise the temperature of the heating table to 120°C, adjust the stirring speed to 1200rpm, and stir for 30min to obtain Modified NPEF-170 epoxy resin.
Embodiment 3
[0033] 1. Weigh 60g of liquid E-51 epoxy resin and put it into a clean beaker, then add 15g of diethylene glycol butyl ether solution and 15g of diethylene glycol ethyl ether acetate into it, and place it on a digital display constant temperature heating platform. Set it to 100°C, and at the same time, stir at a speed of 1200rpm for 15min to obtain a uniform resin solution.
[0034] 2. Slowly add 6g of fumed silica modifier, 15g of diethylene glycol butyl ether solution and 15g of diethylene glycol ethyl ether acetate into the resin solution, raise the temperature of the heating table to 120°C, and adjust the stirring speed to 900rpm, Stir for 50min to obtain modified E-51 epoxy resin.
