TAILIEUCHUNG - Study on uv crosslinking process of diane epoxy resin poly(tetrahydrofurane) divinyl ether system

The effect of diane-epoxy resin (DE) and poly(tetrahydrofurane) divinyl ether (DVE) content on photocrosslinking reaction of DE/DVE system with triarylsulfonium salt (TAS) as photo-initiator were investigated by IR spectra, change of relative hardness and gel fraction. The results showed that increasing DVE content improved some of physico-mechanical properties of photocrosslinked coatings although relative hardness and speed of photocrosslinking reaction reduced. | Journal of Science and Technology 54 (2) (2016) 249-257 DOI: STUDY ON UV-CROSSLINKING PROCESS OF DIANE-EPOXY RESIN/POLY(TETRAHYDROFURANE) DIVINYL ETHER SYSTEM II. INFLUENCE OF EPOXY RESIN AND POLY-(TETRAHYDROFURANE) DIVINYL ETHER CONTENT ON PHOTOCROSSLINKING OF THE DIANE EPOXY/POLY-(TETRAHYDROFURANE) DIVINYL ETHER SYSTEM Dao Phi Hung*, Nguyen Anh Hiep, Mac Van Phuc Institute for Tropical Technology, VAST, 18 Hoang Quoc Viet, Cau Giay, Hanoi * Email: dphung@ Receipted: 3 July 2015; Accepted for publication: 31 October 2015 ABSTRACT The effect of diane-epoxy resin (DE) and poly(tetrahydrofurane) divinyl ether (DVE) content on photocrosslinking reaction of DE/DVE system with triarylsulfonium salt (TAS) as photo-initiator were investigated by IR spectra, change of relative hardness and gel fraction. The results showed that increasing DVE content improved some of physico-mechanical properties of photocrosslinked coatings although relative hardness and speed of photocrosslinking reaction reduced. The changes of functional groups (IR spectra), relative hardness and gel fraction as well as the physico-mechanical properties of UV-cured coatings based on DE/DVE/TAS system illustrated that suitable mass ratio of constituents was 80/20/5. The UV-cured coating based on the system DE/DVE/TAS = 80/20/5 crosslinked completely after seconds UV-exposure and having good physico-mechanical properties: impact resistance reached 180 ; the flexibility obtained 1mm; the adhesion and relative hardness were point 1 and , respectively. Keywords: diane-epoxy resin, poly(tetrahydrofurane) divinyl ether, photocrosslinking. 1. INTRODUCTION Diane-epoxy resin (DE) has been studied and used widely in the industry such as paint, varnish, composite [1 - 3, 6]. However, due to their structure, cured diane-epoxy resin was usually brittle, easy peeling and poor impact resistance and thus reducing the value and scope application of diane-epoxy .
