Capsule type curing agent, curing self-regulation type fiber grid and construction method of curing self-regulation type fiber grid
The invention discloses a capsule type curing agent, a curing self-regulation type fiber grid and a construction method of the curing self-regulation type fiber grid, and relates to the technical field of building reinforcing materials. The capsule type curing agent comprises a shell and an inner core, the shell comprises polyamide and a polystyrene-acrylonitrile copolymer in a mass ratio of 1: (2-3), the inner core is a thiol curing agent, and the mass ratio of the inner core to the shell is 1: (0.5-1). The shell structure can be applied to a fiber grid, the curing process of epoxy resin in the fiber grid can be regulated and controlled, the shell structure is consumed only when heat is released in a hydration reaction, and the stability is good during low-temperature storage; after the shell participates in the reaction, the high-activity curing agent in the shell quickly reacts to accelerate curing of the epoxy resin and enable the epoxy resin to cooperate with mortar solidification. The curing self-regulation type fiber grid is good in flexibility, high in fitting performance and easier to construct before construction and has high rigidity and high load capacity after construction, and therefore the excellent reinforcing effect is guaranteed.
本发明公开了一种胶囊型固化剂、固化自调控型纤维网格及其施工方法，涉及建筑加固材料技术领域。该胶囊型固化剂包括由外壳和内核组成，外壳包括质量比为1：2‑3的聚酰胺和聚苯乙烯‑丙烯腈共聚物，内核为硫醇类固化剂，内核和外壳的质量比为1：0.5‑1。其可以应用于纤维网格中，其可以调控纤维网格中环氧树脂的固化进程，外壳结构在水化反应放热时才被消耗，低温贮存时稳定性良好；外壳参与反应后内部高活性固化剂迅速反应，加速环氧树脂固化使其与砂浆凝固协同。本申请提供的固化自调控型纤维网格在施工前柔性好，贴合性强，更易施工，在施工后具有高刚度、高荷载的能力，从而保证了优异的加固效果。
