| 摘 要： | 通过异佛尔酮二异氰酸酯(IPDI)改性环氧丙烯酸酯(四氢邻苯二甲酸二缩水甘油丙烯酸酯),以此改性预聚物配合活性稀释剂、光引发剂制得紫外光固化涂料。考察了不同—NCO与—OH配比对产物黏度的影响。通过FT-IR对预聚物的结构进行表征,用TGA研究固化膜的热性能,拉伸实验研究固化膜的力学性能。结果表明,反应物中当—NCO与—OH的物质的量比小于1时,—NCO与—OH比值越高则产物的黏度越大;改性后的光固化薄膜的拉伸强度能达到23 MPa以上,断裂伸长率比未改性以前提高了3倍以上,开始热分解的温度为150℃。 |

| Abstract: | The epoxy acrylate(tetrahydrocannabinol phthalate glycidyl acrylate) was modified by IPDI to prepare aprepolymer,which was used to formulate a UV-curing coating together with,active diluent and photoinitiator.The influence of NCO/OH on viscosity of product was investigated.The structure of UV-curing prepolymer was characterized by FT-IR.The thermal properties of cured film were studied by TGA and the mechanical properties were studied by tensile test.The results showed that the higher NCO/OH ratio led to hi... |
