Development of hybrid UV-curable adhesive

摘要: 以自制的杂化溶胶对紫外光固化丙烯酸酯胶粘剂进行改性,得到了具有高粘接强度,对丙酮、乙醇、氯仿等具有明显的耐溶剂性的紫外光固化胶粘剂。实验发现:活性稀释剂中含有较多的羟基、羧基时,此胶粘剂对玻璃的粘接强度较高;胶层粘接力随杂化溶胶用量的增加先增大,后减小,当杂化溶胶中的固体质量为光敏树脂的60%时,胶粘剂的剪切强度达到最大(12MPa)。Abstract: The acrylates organic-inorganic hybrid sol was applied to modify the UV-curable acrylates adhesives. By this way, we prepared a novel kind of UV-curable adhesives, which has good shearing strength and solvent resistance. It's good properties show a promising future in fabrication of ICF targets. The results of the properties tests show that the adhesive has stronger adhering force when the reactive diluent has more hydroxy and carboxyl groups. The content of hybrid sol affects the shear strength and solvent resistance of adhesive, too. When the mass of solid content of hybrid sol reached 60% of UV-cured resin, the shear strength was up to 12MPa, and the adhesive showed perfect solvent resistance.
