摘要：

Acrylate hydroxyl-terminated polyether adhesive (MAPTHF) was synthesized from cationic ring-opening polymerization of polytetrahydrofuran ether diol (PTHF) and oxacyclobutane methacrylate (MMO), then the photo-thermal dual-curing adhesive system was composed of hexamethylenediisocyanate diurea curing agent (N-100), 2,4,6-trimethylbenzoyldiphenylphosphine oxide (TPO) and 1,4-butanediol (BDO), and went through photocuring and thermal curing to further obtain photo-thermal dual-curing adhesion-based elastomer. The MAPTHF was characterized by FTIR, NMR and GPC for structural composition and physical properties. The curing process parameters and the material ratio of the photo- thermal dual-curing system were optimized, with the photo-thermal dual-curing elastomer evaluated for its mechanical properties and thermal stability. The results showed that the target MAPTHF-based adhesive system could be cured quickly within 5 s under ultraviolet light (5 W, 395 nm) and completely cured within 3.0 h under heating, exhibiting the characteristics of fast curing forming and complete curing in a short time. The tensile strength and elongation at break of photo-thermal dual-curing elastomer were 3.15 MPa and 350%, respectively.This photo-thermal dual-curing adhesive system was used for 3D printing of composite propellants, and excellent printing forming effect was obtained. © 2024 Fine Chemicals.
