Abstract

The invention discloses high-temperature-resisting steel perfusion glue. The high-temperature-resisting steel perfusion glue belongs to double-component epoxy structural strengthening glue and comprises a component A and a component B. The component A comprises, by weight, 75-85 parts of epoxy resin 128, 10-15 parts of reactive diluents and 0.5-1.5 parts of silane coupling agent. The component B comprises, by weight, 90-100 parts of modified aromatic amine curing agent. By the adoption of the modified aromatic amine curing agent, the rigidity of cured epoxy resin is improved, the thermal stability of conventional steel perfusion glue is improved, long-term usage at 80-200 DEG C can be achieved, heat resistance is improved greatly, the application range of steel perfusion glue is widened, and the high-temperature-resisting steel perfusion glue keeps the properties of conventional steel perfusion glue including low viscosity, high mobility and good wettability and has unique advantages for building reinforcement in a high-temperature environment.

Description

technical field [0001] The invention relates to the technical field of steel-filling glue, in particular to a high-temperature-resistant steel-filling glue. Background technique [0002] Structural reinforcement is currently an effective measure for reinforcing bridges, roads, housing buildings, reservoir dams and other buildings. Structural reinforcement glue is an important part of the field of structural reinforcement. Common structural reinforcement glues include planting reinforcement glue, steel glue, steel filling glue, crack glue, etc. Among them, steel glue is mainly used for concrete components, masonry components outsourcing steel plate reinforcement, and grouting repair of internal defects of concrete. However, in the reinforcement of high-temperature fields such as thermal power generation and high-temperature pipelines, conventional steel-filling adhesives will cause bonding performance and mechanical properties to decrease significantly in a long-term high-te...
