以丁香酚、甘脲为原料，分别制备二烯丙基丁香酚（ 2A-EU）和无酯键四巯基甘脲（TMGU）。通过调控 n（2A-EU）∶n（TMGU）制备了一系列可 UV固化的涂料，并对其耐热性、固化行为和涂层基本性能、热力学性能、力学性能进行研究，探究了不同 n（C=C）∶n（—SH）对涂料性能的影响。结果表明： 2A-EU和 TMGU被成功合成；随着 TMGU用量的增加，固化后交联网络更为致密，玻璃化转变温度从 22 ℃升高至 50 ℃，初始热分解温度（ T_5%）从 220. 8 ℃升高至 288. 5 ℃，涂层拉伸强度从 0. 67 MPa提高至 15. 79 MPa，对玻璃的附着力从 2级提高至 0级，且涂层具有较好的透明度。

Diallyl eugenol（2A-EU）and tetrathioglycoluril（TMGU）were prepared from eugenol and glycoluril，respectively. A series of thiol-ene UV curable coatings was prepared by adjusting n（2A-EU）∶n（TMGU）， and their heat resistance，curing behavior，coating properties，thermodynamic properties and mechanical properties were studied. Finally，the effects of n（C=C）∶n（— SH）on the properties of the coatings were investigated. The resultsshowed that with the increase of TMGU dosage，the crosslinking network was denser after curing. The glass transition temperature（T_g）of the coating increased from 22 ℃ to 50 ℃，while the initial thermal decomposition temperature（T_5%）increased from 220. 8 ℃ to 288. 5 ℃ and the tensile strength increased from 0. 67 MPa to 15. 79 MPa. The UV-curing coating had good transparency and adhesion to glass.
