Title:

SILICON CHAIN-CONTAINING LOW-TEMPERATURE-RESISTANT FLEXIBLE POLYURETHANE PHOTOSENSITIVE RESIN COMPOSITION FOR PHOTOCURING 3D PRINTING AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2023/050529

Kind Code:

A1

Abstract:

A silicon chain-containing low-temperature-resistant flexible polyurethane photosensitive resin composition for photocuring 3D printing and a preparation method therefor. The composition comprises the following raw materials in parts by weight: 30-80 parts of a silicon chain-containing low-temperature-resistant flexible polyurethane prepolymer, 5-10 parts of polyurethane acrylate resin, 35-70 parts of a reactive diluent, 1.0-5.0 parts of a photoinitiator, and 0.1-1.0 part of an antioxidant. The silicon chain-containing low-temperature-resistant flexible polyurethane photosensitive resin composition has higher reaction activity, can be used for conventional SLA, DLP, LCD and other desktop-level 3D printing devices, and moreover, a printed product contains a silicon chain, and is good in low-temperature resistance, small in shrinkage rate, resistant to aging and excellent in mechanical property.
