The invention discloses transparent epoxy silk-screen glue and a silk-screen printing bonding process, and belongs to the technical field of high-molecular compounds and adhesives. The silk-screen glue only needs two reactants, modifiers such as toughening agents do not need to be added, the silk-screen glue can be rapidly cured within 10 seconds, and a cured product of the silk-screen glue has the advantages of being firm in bonding, high in toughness, large in hardness, high in stability, high in transparency, low in moisture absorption and the like. The silk-screen glue is green, environment-friendly, low in cost, simple and controllable in preparation process, capable of flexibly designing and adjusting the silk-screen process according to requirements, and very suitable for industrial production. 本发明公开了一种透明环氧丝印胶及丝网印刷粘接工艺，属于高分子化合物和胶黏剂技术领域。所述丝印胶仅需2种反应物，无需添加增韧等改性剂，所述丝印胶能达到10秒快速固化，其固化物具备牢粘接、高韧性、大硬度、高稳定、高透明和低吸湿等特点。本发明的丝印胶绿色环保、成本低、制备工艺简单可控，可根据要求灵活设计调整丝印工艺，极适合工业化生产。
