Abstract

The invention discloses a bio-based water-based anticorrosive force-sensitive conductive coating for bridge building protection and health monitoring, which comprises a bio-based resin, an assistant,deionized water, a cosolvent, a pigment and a conductive filler, and the conductive filler comprises nano carbon black, carbon nanotubes, Mxene, silver nanowires or nickel nanowires. Bio-based resin is used as a main film forming matter, so that the production of the product is environmentally friendly and in line with sustainable development. The conductive filler is added, so that the prepared bio-based water-based anti-corrosion force-sensitive conductive coating not only has corrosion resistance, but also has conductivity and sensitive sensitivity, thereby being used for stress detection or bridge deformation detection.

Description

Technical field: [0001] The invention relates to the technical field of coatings, in particular to a bio-based water-based anti-corrosion force-sensitive conductive coating used for bridge building protection and health monitoring. Background technique: [0002] The service life of bridge buildings is a major key issue affecting its safety. The key is that metal materials and structural parts are affected by environmental corrosion and stress damage during use. Therefore, in order to prolong the service life, it is particularly important to monitor its corrosion protection and stress damage. [0003] The corrosion of metal materials is mainly caused by the electrochemical reaction of moisture and oxygen in the air. Therefore, epoxy resins with good weather resistance, corrosion resistance, stability and mechanical properties are often used as anti-corrosion coatings to isolate moisture and oxygen. Among them, water-soluble epoxy ester is the current key development directi...
