Title:
PHOTOCURABLE RESIN BASED ON EPOXIDIZED VEGETABLE OIL AND GALLIC ACID, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/284021
Kind Code:
A1
Abstract:
Disclosed are a photocurable resin based on epoxidized vegetable oil and gallic acid, and a preparation method therefor and an application thereof. First, gallic acid and an acrylic anhydride compound are reacted to obtain a gallic acid triacrylate/acrylic compound mixed intermediate; an epoxy ring-opening reaction is then carried out using epoxidized vegetable oil and the obtained mixed intermediate to obtain a novel bio-based epoxy acrylate prepolymer; finally, a diluent monomer, a photoinitiator, a polymerization inhibitor, etc. are added and dispersed uniformly to obtain a bio-based photocurable resin. The obtained resin has advantages including low viscosity and high curing speed, and has excellent mechanical and thermodynamic properties after curing. Therefore, it can be used as a base resin for applications such as photocurable 3D printing materials, coatings, and inks. The present method is simple and environmentally friendly, and most of the raw materials come from renewable resources, so that the method has great significance for promoting sustainable development of photocurable materials.
