双重固化体系柔韧性研究

摘要

In order to obtain UV-heat curing coatings which has great flexibility, UV-heat curing coatings were made through the principle of formulating of recipe. The effect of different prepolymer and monomer on UV-heat curing coatings has been studied. The sample is prepared by the most optimal formula. The experiment shows that Flexibility is best when using monomer EOEOA preparing dual curing coating. Moreover, 3 kinds of prepolymer and monomer with preferably flexibility are selected to conduct experiments, dual curing coatings with high flexibility is prepare using the experimental formula, in which hybrid prepolymer LR9000︰UA VP 2396︰ SE-400=0. 378︰0. 287︰0. 334.%为了获得柔韧性能良好的热-UV双重固化涂料，利用配方设计原理制备了热-UV双重固化涂料样品，分别探讨了预聚物和单体含量对双重固化涂层柔韧性的影响，使用最优配方制备柔韧性最佳涂料样品。实验表明，单体中采用EOEOEA制备双重固化涂料柔韧性最好，选用混合预聚物LR9000︰UA VP 2396︰SE-400=0．378︰0．287︰0．334制备了具有较高柔韧性双重固化涂料。
