Light-heat dual-curing polyurethane acrylate resin as well as preparation method and application thereof
The unfriendliness of small molecule curing agents to the environment and lack of chemical bond crosslinking are solved by using a combination of hydroxy and amino-terminated polyurethane prepolymer, blocked isocyanate acrylate functional monomer and diluted monomer in a dual curing photosensitive resin. The problem of this achieves the effect of extending the use time and improving the performance of the material.

AI Technical Summary
The existing double curing photosensitive resin materials have small and medium-sized curing agents that are not friendly to the environment, have a large odor and affect physical health. There is a lack of chemical bond crosslinking between acrylate resin and polyurethane resin, which limits the improvement of material performance.
The light-thermal double curing polyurethane acrylate resin is used to form a synergistic compound to extend the time of the resin by combining hydroxy and/or amino-terminated polyurethane prepolymer, blocked isocyanate acrylate functional monomer and diluted monomer. And improve mechanical properties and solvent resistance.
It effectively reduces the odor of the resin, extends the use time, and improves the mechanical properties and solvent resistance of the material by forming a dense cross-linked interpenetrating network structure.
