The invention discloses an epoxy resin cementing material for retard-bonded prestressed tendons. The epoxy resin cementing material comprises bisphenol A epoxy resin, dicyandiamide, a flexibilizer, adiluent and a filler; by uniformly stirring the bisphenol A epoxy resin, the dicyandiamide, the flexibilizer, the diluent and the filler, and fully grinding the mixture, cementing material slurry is obtained; the prepared slurry is used as the cementing material of the retard-bonded prestressed tendons needing to be heated and cured. The cementing material has good stability under the room temperature condition, the working life is 6-12 months, and it can be guaranteed that the performance of the retard-bonded prestressed tendons is stable from the production period to the tensioning period. And through a heating method, the epoxy resin cementing material is rapidly cured, so that a steel strand is bonded with concrete in time according to requirements.
一种缓粘结预应力筋用环氧树脂胶凝材料，包括双酚A型环氧树脂、双氰胺、增韧剂、稀释剂、填料；混合料搅拌均匀，混合料充分研磨，得到胶凝材料浆料；制备好的浆料作为需要加热固化的缓粘结预应力筋的胶凝材料使用。胶凝材料在室温条件下有较好的稳定性，适用期6～12个月，能保证缓粘结预应力筋从生产到张拉期的性能稳定。通过加热的方法，使环氧树脂胶凝材料的迅速固化，使钢绞线按要求及时与混凝土粘结。
