Claim:
A preparation method of epoxy/modified silicon dioxide corrosion resistant nanocomposite material, comprising the steps of: dispersing tetraethyl orthosilicate-silicon dioxide (TEOS-SiO 2 ) or 3-aminopropyltriethoxysilane (APTES)/TEOS-SiO 2 in a solvent to form a TEOS-SiO 2 solution or a APTES/TEOS-SiO 2 solution; adding triphenylolmethane triglycidyl ether and 1,4-butanediol diglycidyl ether into the TEOS-SiO 2 solution or APTES/TEOS-SiO 2 solution to produce glycidyl ether/TEOS-SiO 2 solution or glycidyl ether/APTES/TEOS-SiO 2 solution; adding a curing agent into the glycidyl ether/TEOS-SiO 2 solution or glycidyl ether/APTES/TEOS-SiO 2 solution to generate epoxy/TEOS-SiO 2 solution or epoxy/APTES/TEOS-SiO 2 solution; and curing the epoxy/TEOS-SiO 2 solution or the epoxy/APTES/TEOS-SiO 2 solution to produce epoxy/modified silicon dioxide nanocomposite corrosion resistant material while the epoxy/modified silicon dioxide is epoxy/TEOS-SiO 2 or epoxy/APTES/TEOS-SiO 2 , wherein during said curing process a temperature is elevated from room temperature to 50° C. to be maintained at said 50° C. for 11-12 hours, wherein the temperature is further increased from said 50° C. to 80° C. to be maintained at said 80° C. for 0.5 hour with the following increase of the temperature from said 80° C. to 100° C. to be maintained at said 100° C. for 6-8 hours, wherein the temperature is further increased from said 100° C. to 120° C. to be maintained at said 120° C. for 0.5 hour, and wherein the temperature is consequently decreased from said 120° C. to the room temperature; wherein the TEOS-SiO 2 or the APTES/TEOS-SiO 2 constitutes 1-10 wt % of the epoxy/modified silicon dioxide nanocomposite corrosion resistant material.
