Embodiment 1
[0019] Weigh 10.2g of bisphenol A epoxy resin (E51) and mix it with 6.0g of polyether amine (D400), and stir mechanically at 100°C for 2h to obtain the E51-D400 prepolymer; add an appropriate amount of acetone to dissolve the prepolymer, drop Add the acetone solution of hydrochloric acid, wherein the amount and concentration of the substance of hydrochloric acid are 0.5 times of the amount and concentration of amino groups in the prepolymer solution, and magnetically stirred for 3h in the ice-water bath to obtain the E51-D400 prepolymer semi-ammonium salt; 30g An aqueous solution of montmorillonite (100 mmol / 100 g of CEC) was dropped into the E51-D400 prepolymer semi-ammonium salt solution, heated and stirred at 70° C. for 4 hours to obtain E51-D400 prepolymer-modified montmorillonite. Add 3g of modified montmorillonite corresponding to montmorillonite to 61g of E51 resin, mechanically stir for 30h, and ball mill for 60h; vacuumize at room temperature to remove the solvent, and...
Embodiment 2
[0021] Weigh 5.1g of E51 and mix with 3.0g of D400, stir mechanically at 100°C for 2 hours to prepare E51-D400 prepolymer and add appropriate amount of acetone to dissolve; drop the E51-D400 prepolymer solution into 1g of graphene oxide aqueous solution , and stirred at room temperature for 2 h to obtain E51-D400 prepolymer-modified graphene oxide. Add 0.5g of modified graphene oxide corresponding to graphene oxide to 61g of E51 resin, mechanically stir for 30h, and ball mill for 60h; vacuumize at room temperature to remove the solvent, and continue ball milling for 30h; then, add 38g of curing agent D400, mechanically stir evenly and continue Ball mill for 30-60 minutes; finally, vacuumize to remove air bubbles, pour the mixed system into a mold, and cure at 75°C for 2 hours, at 115°C for 2 hours, and at 150°C for 2 hours.
Embodiment 3
[0023]Weigh 1.8g of m-phenylenediamine (mPDA), heat to 115°C for 15min, cool down to 40°C naturally, add 4,5-epoxycyclohexane-1,2-dicarboxylic acid diglycidyl ester at 60°C Resin (TDE85) 10.0g, mechanically stirred at 40°C for 3 hours to prepare TDE85-mPDA prepolymer; add appropriate amount of acetone to dissolve the prepolymer, drop in acetone solution of hydrochloric acid, wherein the amount and concentration of hydrochloric acid are the prepolymer 0.5 times the amount and concentration of amino groups in the solid solution, magnetic stirring reaction under ice-water bath for 3h, to obtain TDE85-mPDA prepolymer semi-ammonium salt; 30.0g montmorillonite (CEC is 100mmol / 100g) aqueous solution was dripped into TDE85- mPDA prepolymer semi-ammonium salt solution, heated and stirred at 60° C. for 4 hours to obtain TDE85-mPDA prepolymer modified montmorillonite. Add 3.0g of modified soil corresponding to montmorillonite to 82.2g of TDE85 resin, mechanically stir for 30h, and ball m...
