How to improve the hydrophobic properties of thermal paper coatings?

Thermal printing paper is a kind of information paper with thermal recording effect that uses paper as a carrier and is coated with thermal heating coating. structure is more complex.

The thermal layer is the key to thermal color development; the coating is to provide the thermal paper with waterproof, oil-proof, and solvent-resistant functions; the bottom layer is to improve the smoothness and heat insulation of the paper, and the adhesive layer is to control the thermal paper. Warpage and penetration.

Adding Tianshi wax emulsions to the top coat or back coat can effectively improve the hydrophobic properties of the thermal paper coating, play a lubricating role, prevent the thermal print head from being bonded by the coating, reduce excessive wear, and improve the wear resistance of the coating. Smoothness, thereby providing high color strength; at the same time, it can also reduce the coefficient of friction between adjacent papers, avoid the phenomenon of banding, and prolong the storage period of thermal paper.
