Abstract:
Disclosed are a highly functional natural material-derived epoxy resin, a preparation method therefor, and an epoxy resin curing composition using the same. The highly functional natural material-derived epoxy resin represented by chemical formula 1 is obtained by reacting a compound, represented by chemical formula 2, and epichlorohydrin (ECH), which is obtained by using glycerin as a starting material, in the presence of a hydroxide salt.

Claim (Index 3):
A method of preparing the natural material-derived epoxy resin, the method comprising:\n a first step including mixing 550 to 650 parts by weight of epichlorohydrin (ECH) obtained from glycerin as a starting material with 100 parts by weight of a compound represented by the following Formula 2, dissolving the mixture at an elevated temperature of 60 to 75\u00b0 C., adding 5 to 11 parts by weight of sodium hydroxide (NaOH) to 100 parts by weight of a compound represented by the following Formula 2 and conducting preliminary reaction for 2 to 4 hours; a second step including conducting main reaction of the reactants of the first step at a temperature of 60 to 75\u00b0 C. and at a reduced pressure of 180 to 250 torr, the main reaction being carried out for 3 to 6 hours by adding 44 to 60 parts by weight of sodium hydroxide (NaOH) to 100 parts by weight of the compound represented by the following Formula 2; a third step including standing the reaction solution after reaction of the second step, separating the supernatant by reverse aliquoting and filtering the same; and a fourth step including collecting epichlorohydrin from the filtrate. wherein n is a natural number of 0 to 300,
