Abstract
The present invention discloses an acrylate oligomer, the acrylate oligomer is obtained by a reaction of isocyanate group-terminated oligomer and formate-terminated ethylene glycol methacrylate. After the acrylate oligomer provided by the present invention is photocured, the molecular structure, cross-linking density and other network structure characteristics of the acrylate oligomer can be changed through specific post-processing. Since the formate component formed after heat treatment has no water absorption and has a low glass transition temperature, the final material obtained after heat treatment has a lower water absorption rate and glass transition temperature. The present invention also provides a preparation method and an application method of the acrylate oligomer.
