The invention relates to the technical field of epoxy resin curing agents, in particular to a pH response type epoxy resin curing agent as well as a preparation method and application thereof, and aims to solve the problems that epoxy resin and a curing agent are stored separately and need to be mixed before filling, and the filling time is shortened to a certain extent. Epoxy resin and a curing agent are mixed and react to generate a net-shaped three-dimensional polymer, the polymer is high in viscosity and poor in flowability, and cracks can be filled with the mixture only through manual assistance. The pH response type epoxy resin curing agent is prepared from the following raw materials in parts by weight: 15 to 40 parts of thiocarboxylic acid, 15 to 40 parts of aliphatic polyamine, 2 to 6 parts of a dehydrating agent, 45 to 60 parts of fluorine-containing fatty acyl chloride and 120 to 160 parts of an organic solvent.
本申请涉及环氧树脂固化剂技术领域，具体而言，涉及一种pH响应型环氧树脂固化剂及其制备方法和应用，一定程度上可以为了解决环氧树脂与固化剂分开储存以及在填补之前需将两者混合，由于环氧树脂与固化剂混合发生反应后生成网状立体聚合物，该聚合物粘度大、流动性差，需要人工辅助才能使混合物充满裂缝的问题。所述pH响应型环氧树脂固化剂包括：所述固化剂由以下原料按照重量份组成：15‑40份硫羧酸、15份‑40份脂肪族多元胺、2份‑6份脱水剂、45份‑60份含氟脂肪酰氯、和120份‑160份有机溶剂。
