1results about How to "Improve light curing efficiency" patented technology

This invention belongs to the field of photocurable polymer materials technology, specifically relating to a high-strength, wear-resistant resin composition and artificial nails. The composition comprises the following components in the indicated proportions: 100 parts by weight of modified polyurethane acrylate, 50-150 parts by weight of reactive diluent monomer, and 1-10 parts by weight of photoinitiator. The modified polyurethane acrylate is obtained by first-step carbamate reaction of cyclohexanehexyl alcohol with alicyclic or aromatic diisocyanate to obtain an isocyanate-terminated oligomer, followed by a second-step carbamate reaction with (meth)acrylate hydroxyl ester, resulting in a hexafunctional polyurethane acrylate with a clustered dispersion structure. Compared to conventional multifunctional polyurethane acrylates, the resulting composition exhibits higher photocuring efficiency, and the artificial nails prepared after curing have higher strength and wear resistance.
