AI Technical Summary

Technical Problem

Conventional UV-cured resin compositions for artificial nails suffer from a lack of rigid segments, resulting in insufficient strength and abrasion resistance. Furthermore, adding fillers to improve abrasion resistance affects transparency and toughness, leading to increased costs.

Method used

Modified polyurethane acrylates are used, which are formed by reacting cyclohexanehexyl alcohol with alicyclic or aromatic diisocyanates and (meth)acrylate hydroxy esters to form a cluster-dispersed hexafunctional polyurethane acrylate, thereby improving photocuring efficiency and crosslinking density.

Benefits of technology

It significantly improves the strength and abrasion resistance of UV-cured resins while maintaining good transparency and toughness, and reduces costs.

Abstract

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.
