Problems solved by technology

[0003] The current identification of grid equipment usually uses IoT tags, such as RFID, two-dimensional code tags, etc., but these lifespans are often short, and the main equipment of the grid has an operating life of 20-30 years. The produced QR code pattern has a short service life and cannot match the service life of the equipment
With the widespread application of RFID and QR code tags in daily life, how to make IoT tags have a longer service life in complex working environments has gradually become an important issue, and the optimization research work in this area has not been reported yet.

Embodiment 1

[0019] Select the RFID of the ABS shell used by the State Grid Corporation of China, and use laser engraving technology (the laser repetition rate is 20 kHz, the engraving line speed is 400 mm / s) to process the two-dimensional code pattern on the ABS surface (such as figure 1 shown), and then apply UV metal ink to the pattern part of the two-dimensional code. The oil is 30g / L NaOH, 50g / L NaOH 2 CO 3 , soak for 5 minutes at room temperature; the roughening solution is 360g / L chromic acid and 350g / L sulfuric acid, soak for 5 minutes at 70°C, wash with distilled water and dry quickly with a hair dryer. Finally, a layer of highly weather-resistant modified silicone varnish with a thickness of 60 μm is coated on the entire label surface, and the modification method is to add 1 wt % epoxy resin microcapsules. The appearance of the obtained IoT label is as follows figure 2 As shown, the long-life Internet of Things label of the present invention still keeps the two-dimensional co...

Embodiment 2

[0021] Select the RFID of the PET shell of the State Grid Corporation of China, use laser engraving technology (laser repetition frequency is 30 kHz, engraving line speed is 300 mm / s) to process the two-dimensional code pattern on PE, and then paint the two-dimensional code pattern part Brush UV metal ink. After the ink is cured, the surface is decontaminated and degreased, roughened, washed with water and dried. The decontamination is washed with absolute ethanol, and the degreasing liquid is 60g / L NaOH, 20g / L NaOH 2 CO 3 , soak for 10 minutes at room temperature; the roughening solution is 400g / L chromic acid and 320g / L sulfuric acid, soak for 10 minutes at 60°C, wash with distilled water and dry quickly with a hair dryer. Finally, a layer of highly weather-resistant modified fluorocarbon varnish with a thickness of 80 μm is coated on the entire label surface. The modification method is to add 1wt% benzotriazole and 1wt% nano-TiO 2 . The long-life Internet of Things label ...

Abstract

The invention discloses a preparation method of a long-life internet of things label for power grid equipment in an outdoor atmospheric environment. After the two-dimensional code pattern is processed on the surface of the RFID shell, a long-life IoT label is prepared by painting the surface of the label with UV-resistant ink and highly weather-resistant modified varnish. In the present invention, through the optimization of the surface treatment process and the modification of the varnish, the compatibility problem of multi-layer materials is solved, and the service life of the label of the Internet of Things is improved. The method not only has a simple preparation process and high production efficiency, but also the obtained IoT label has multiple recognizability, good weather resistance and impact resistance in an outdoor atmospheric environment, and the service life is effectively improved.

Description

technical field [0001] The invention relates to a preparation method of a long-life Internet of Things label for power grid equipment in an outdoor atmospheric environment, and belongs to the technical field of label production. [0002] technical background [0003] The current identification of grid equipment usually uses IoT tags, such as RFID, two-dimensional code tags, etc., but these lifespans are often short, and the main equipment of the grid has an operating life of 20-30 years. The produced QR code pattern has a short service life and cannot match the service life of the device. With the widespread application of RFID and QR code labels in daily life, how to make IoT labels have a longer service life in complex working environments has gradually become an important issue, and the optimization research work in this area has not been reported yet. . Among many tags, RFID tags have been widely used in the power industry, chemical industry, and construction industry d...
