Abstract

The invention relates to the technical field of chemical engineering, and particularly discloses an epoxy curing agent . The epoxy curing agent is prepared from, by weight, 65-90% of a main curing agent, 0-10% of a modifier, 0-10% of a diluent and 10-15% of accelerants, wherein the main curing agent is any one of pentaerythritol tetra(3-mercaptopropionate), polypentaerythritol tetra(3-mercaptopropionate) and polymercaptan; and the accelerants are at least two of triethanolamine, N, N-dimethyl benzylamine, 2, 4, 6-tri(dimethylaminomethyl)phenol, N, N-dimethyl octylamine and tri-octyl decyl alkyl tertiary amine, and the accelerant is at least two of triethanolamine, N, N-dimethyl benzylamine, 2, 4, 6-tri(dimethylaminomethyl) phenol, N, N-dimethyl octylamine and tri-octyl decyl alkyl tertiary amine. The tertiary amine accelerants with different activities are used for accelerating curing of the mercaptan / polymercaptan epoxy curing agent, so that the usable time of the mercaptan / polymercaptan epoxy curing agent can be effectively prolonged, and the application range of the mercaptan / polymercaptan epoxy curing agent is expanded. In addition, the preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an epoxy curing agent and a preparation method thereof. Background technique [0002] At present, mercaptan / polymercaptan epoxy curing agents can be cured quickly at room temperature (low temperature), and can achieve high bonding strength (more than 80% of final curing performance) in a short time (1 to 2 hours), but usually The mercaptan / polymercaptan epoxy curing agent used can be used for a short time, generally only 3 to 5 minutes at room temperature. When outdoor repair works in cold winter areas, rapid repair of traffic roads, rapid repair of airport runways, etc. require a certain amount of time to operate, but require quick use in application scenarios, the existing mercaptan / polymercaptan Epoxy curing agent is obviously difficult to meet the actual use requirements. Contents of the invention [0003] The object of the present invention is to provide a kind...
