Abstract

The invention discloses anti-seismic epoxy dipping glue and a preparation method thereof. To be specific, the dipping glue comprises a component A and a component B in a weight part ratio of 3 to 1; the component A comprises 50.0-75.0 parts of bisphenol A epoxy resin, 5.0-20.0 parts of epoxy acrylate, 10.0-20.0 parts of hydrogenated bisphenol A epoxy resin, 2.0-8.0 parts of diluents, 5.0-15.0 parts of toughening agents, 1.0-6.0 parts of a thixotropic agent, 0.1-0.5 parts of an anti-aging agent, 0.5-1.0 part of peroxides, and 0.1-1.0 part of rheological additives; the component B comprises 20.0-40.0 parts of an aliphatic amine curing agent, 40.0-60.0 parts of an alicyclic amine curing agent, 0.5-2.0 parts of accelerants, 1.0-4.0 parts of coupling agents and 1.0-15.0 parts of a thixotropic agent. The dipping glue is prepared by respectively preparing the component A and the component B, and mixing the components A and B, and is mainly used for gluing carbon fiber composite materials used for reinforcing buildings in areas with the seismic fortification intensity of not less than level 7; the intensity index of the dipping glue is in line with performance indexes in Engineering Structure Strengthening Material Security Identification Technical Specification of GB50728-2011.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an anti-seismic epoxy impregnated glue and a preparation method thereof. Background technique [0002] With the development of my country's economic construction and the continuous development of the construction industry, people pay more and more attention to the safety of building structures. In recent years, there have been many catastrophic earthquakes at home and abroad. Many buildings and bridges collapsed or were severely damaged in the earthquakes, causing a large number of casualties and bringing huge economic losses to the country. Therefore, the requirements for the anti-seismic grade of buildings and the reinforcement materials used for anti-seismic are also getting higher and higher. [0003] At present, the reinforcement methods of reinforced concrete seismic structures commonly used in engineering mainly include the reinforcement method of e...
