Abstract
The invention discloses a method and device for preparing a photo-thermal cured electrostatic spraying film, and belongs to the technical field of film preparation and electrostatic atomization, and the device comprises a device supporting unit, an electrostatic spraying unit, a photo-thermal curing unit and a film collecting unit. The photo-thermal mixed liquid is deposited on the receiving cloth through the electrostatic spraying technology, the photo-thermal curing resin is subjected to a curing reaction in combination with ultraviolet light-thermal mixing curing, a layer of uniform and compact thin film is formed and then collected, and the problems that traditional thin film preparation is low in efficiency, the thin film is prone to damage and difficult to collect, and expensive equipment is needed are solved. The curing forming process is high in operability and high in curing speed, and the film has high mechanical performance. Large-area customization and storage of the film can be realized, the device is simple and effective, and the film preparation cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of film preparation and electrostatic atomization, and in particular relates to a method and a device for preparing a photothermally cured electrostatic spray film. Background technique [0002] Electrostatic spraying uses high-voltage static electricity to break and refine the charged liquid, which can improve the spraying effect and improve the quality of film forming. It is a new type of film preparation technology with the advantages of strong controllability, simple equipment and low cost. Low efficiency, fragile membranes, difficult to collect, requiring expensive equipment, etc. Electrostatic spraying has the characteristics of depositing tiny droplets, and by uniformly depositing tiny droplets on the target substrate, dense films can be obtained. [0003] At present, the films formed by electrostatic spray photocuring have low mechanical properties and long thermal curing time. The electrostatic sp...
