<p>In recent years, with the large-scale excavation of Neolithic jade artifacts, the demand for the protection and restoration of deteriorated jade has increased significantly. To develop a new generation of green, environmentally friendly, and easy-to-operate jade adhesive, a light-curing jade adhesive was prepared in this study. The jade adhesive was composed of urethane dimethacrylate (UDMA), 9,9-Bis[4-((2-(2-methacryloyloxy)ethylcarbamate)ethoxy)-phenyl]fluorene (Bis-EFMA), hydroxyethyl methacrylate (HEMA) and di[2-(methacryloyloxy)ethyl] phosphate (DMAP). Among them, Bis-EFMA is a hydrophobic monomer with a high refractive index, used to enhance photopolymerization efficiency; HEMA is a low-viscosity hydrophilic monomer, used to dissolve various components; UDMA is an amphiphilic monomer, used to promote compatibility among components; DMAP is a phosphate ester monomer, used to establish chemical bonding with jade. The formulation without DMAP was designated as the blank control group, and commercial instant adhesive was designated as the commercial control group. The optimized adhesive demonstrated superior performance characteristics, including a high degree of conversion, enhanced flexural strength, flexural modulus, tensile strength, tensile modulus, and toughness. Notably, the DMAP-modified adhesive exhibited significant improvements in contact angle and shear bond strength compared to the control groups. Specifically, as the mass fraction of DMAP increased from 5wt.% to 15wt.%, CA decreased significantly. However, there was no significant change in SBS. The prepared light-curing jade adhesive is expected to be utilized in the adhesive repair method during the jade restoration process, offering a novel solution for the protection and restoration of jade cultural relics.</p>
