Title:
LOW-TEMPERATURE-RESISTANT FLEXIBLE PHOTOSENSITIVE RESIN COMPOSITION FOR PHOTOCURING 3D PRINTING AND PREPARATION METHOD FOR LOW-TEMPERATURE-RESISTANT FLEXIBLE PHOTOSENSITIVE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/050530
Kind Code:
A1
Abstract:
Disclosed are a low-temperature-resistant flexible photosensitive resin composition for photocuring 3D printing and a preparation method for the low-temperature-resistant flexible photosensitive resin composition. The composition comprises the following raw materials in parts by weight: 5-40 parts of a silicon-containing chain polyurethane prepolymer end-capped with an acrylic acid group, 20-60 parts of a flexible polyurethane prepolymer end-capped with an acrylic acid group, 5-10 parts of a polyurethane acrylate resin, 20-70 parts of a reactive diluent, 1.0-5.0 parts of a photoinitiator, and 0.1-1.0 part of an antioxidant. The low-temperature-resistant flexible photosensitive resin composition for photocuring 3D printing has high reactivity and can be used for conventional SLA, DLP and other desktop-level 3D printing devices. Moreover, the printed product contains a silicon chain, has good low temperature resistance, a small shrinkage rate, is not prone to yellowing, and has excellent mechanical properties.
