Problems solved by technology

[0002] Concrete is an important part of building materials. It has many advantages such as easy material acquisition and good durability, and is widely used in construction projects, bridge projects, water conservancy projects and traffic projects. However, it is prone to cracks during production, maintenance and use. , honeycomb, pitted surface and defects and other diseases, these diseases affect the appearance of the concrete structure, and even affect the durability of the structure, therefore, it is necessary to repair and protect the concrete
[0003] In the field of building structure repair and protection, the isolated concrete durability repair and protective coating structure introduced in recent years is in the ascendant, and has good applications in bridges, highways and buildings. The system is green, environmentally friendly, and has excellent performance. The repair and protection effect is good, but the epoxy putty used in this system is paste-like and has a high viscosity, so it can only be applied by batch scraping. The construction efficiency is low, and the appearance is greatly affected by the proficiency, especially on curved surfaces, Special-shaped structures are more difficult to construct
If a spray-on epoxy putty can be developed, it can well solve the construction defects of the paste epoxy putty, but there is no relevant report on the spray-on epoxy putty
