The present invention provides a modified phytic acid derivative resin, which comprises reaction products of the following components: 35-65 wt. % of phytic acid, 20-65 wt. % of an epoxy compound containing a double bond, and 0-35 wt. % of a bifunctional epoxy compound, based on the total weight percentage of the modified phytic acid derivative resin as 100 wt. %. The present invention further provides a light-curable liquid flame-retardant resin, which comprises, based on the total weight percentage of the liquid flame-retardant resin as 100 wt. %, 79-99.9 wt. % of the modified phytic acid derivative resin, 0-20 wt. % of a polyurethane acrylate resin, and 0.1-5 wt. % of a photoinitiator. After the liquid flame-retardant resin is cured, a flame-retardant film is obtained. The flame-retardant film has optimal flame-retardant properties and optimal mechanical properties. |
