Example Embodiment
[0017] Embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0018] First, protect the metal terminal 2 of the carbon nanotube cement-based composite sensor, and cover it with a protective cover to prevent it from being damaged or soiled when applying adhesive or paint. Apply adhesive on each surface of the carbon nanotube cement-based composite sensor. Or paint, such as epoxy resin, etc., to make coating 3, before the coating is completely hardened, roughen the surface to make the surface rough enough. Remove the protective cover of the carbon nanotube cement-based composite sensor terminal, and the sensor coating can be used for engineering after it is completely hardened.

The invention discloses a carbon nanometer tube cement based composite material sensor encapsulating method. A protecting cover is covered on a carbon nanometer tube cement based composite material sensor metal binding post. A thin layer of coating or adhesive substances is evenly painted on each surface of a sensor prismoid, wherein the coating or the adhesive substances are corrosion-resistant, heat-insulating, humid-preventing, insulating, and capable of being hardened. Before the coating or the adhesive substances are completely hardened, roughening is conducted on the surfaces so as to enable the surfaces to be rough enough. The protecting cover is removed from the carbon nanometer tube cement based composite material sensor metal binding post, and a sensor is encapsulated after the coating is completely hardened. After encapsulated through the method, the carbon nanometer tube cement based composite material sensor has the advantages of being corrosion-resistant, heat-insulating, humid-preventing, insulating, and the like, is not influenced by outside environments in project structure health monitoring, is reliable in detected data, and reduces detection errors. Moreover, the sensor can be firmly adhered to concrete environment media.
Description
technical field [0001] The invention relates to a method for encapsulating and manufacturing a sensor for engineering structure monitoring. Background technique [0002] Carbon nanotube cement-based composite sensor can be used for real-time health monitoring of engineering structures, ensuring the matching between the sensor and the concrete environment medium, reducing measurement errors, and playing an important role in major engineering disaster prevention and mitigation as well as engineering safety and reliability. In the real-time health monitoring system of engineering structure, the sensor subsystem is the front-end and most basic subsystem of the health monitoring system, which is composed of multiple sensors and sensor networks. Sensors can be used to perceive the load and response information of structures, and output them in the form of physical quantities such as electricity, light, and sound. The currently developed sensing materials and sensing elements main...
