Self-healing resin composition and self-healing membrane structure

Abstract

A self-healing resin composition and a self-healing membrane structure are provided. The self-healing resin composition includes 20 phr to 50 phr of a self-healing resin, 1 phr to 10 phr of a hardener, 0.1 phr to 3 phr of a matting agent, and 40 phr to 80 phr of a solvent. The self-healing resin is polymerized from a polyester polyol, a diisocyanate monomer, and a bisphenol monomer. A molar ratio of a hydroxyl group to an isocyanate group in monomers to polymerize the self-healing resin ranges from 1.33 to 2.0. A number average molecular weight of the self-healing resin ranges from 30,000 g/mol to 200,000 g/mol.
