摘要

Urushiol (UR) was a kind of natural paint with a long history and excellent performance. Its high price restricts its development. For the sake of the sustainable development of UR, we prepared a new urushiol based coating composition which is of degradation. To be more specific, we develop a blend by diallyl trisulfide (TS) and urushiol, in which a free radical copolymerization process would take place to form a coating composition under UV irradiation. In this work, FT-IR was used to prove the reaction proces; the reversibly cross-linking properties and the rheological properties were also been proved; the basic mechanisms active in microstructure and the associated surface energy was elucidated; mechanical analysis and showed the mechanical property of coating composition. It was found that a copolymer formed by copolymerization of diallyl trisulfide and urushiol. The introduction of trisulfide bonds assists in achieving the reversibly cross-linking under extreme alkalinity (pH 8). various trisulfide densities brought about different microstructures on the modified urushiol. The surface energy of coating composition had been enhanced after UV-curing and its increase was related to the phase inversion (represented by microstructure). What was more, the existence of flexible segments offered the coating composition with excellent flexibility (2 mm) and rheological properties (15 MPa.S), while the hardness of coating dropped to 2H.
