Problems solved by technology

[0002] It is widely used in various packaging fields and has broad development prospects. At present, most of the film and paper coating processes at home and abroad are aimed at solvent-based coatings. This coating process has certain defects: the current coating process The material system is mainly based on the automatic feeding system, which is easy to cause layering of the coating, thus affecting the uniformity of the coating
The extracted paint enters from the side of the trough and is in contact with the air. It is easy to form air bubbles after entering the trough, which will affect the coating process; and the solvent-based paint is easy to volatilize, which may cause changes in the solid content of the paint and affect the coating process. It also causes harm to the health of production personnel and pollutes the environment
Most of the troughs have no temperature control, and the paint is easily affected by the ambient temperature, which will damage the viscosity of the paint and cause uneven coating
The mesh opening of the anilox roller is mostly diamond-shaped with four sides, and the line ratio is low, which may easily cause the coating to spread during the coating process. It is only suitable for printing large-area solid color patches or images with low requirements.

Abstract

The invention discloses a process for producing ketone-free transferring card paper. According to the process, an aqueous coating with a ketone removing function is utilized and is fed by a feeding system; then processes of coating by an anilox roller, drying by a drying system and the like are carried out to prepare the ketone-free transferring card paper. The process is simple and can utilize a water-based coating to coat the card paper, so that the problems of personal safety, environmental pollution and high cost, caused by an organic solvent type coating used in the prior art are effectively solved; the obtained ketone-free transferring card paper has a uniform coating and has no remains of butanone.
