Description

Technical Field

[0001] The utility model belongs to the technical field of thermal paper production, and relates to a coating brushing device for thermal paper production. Background Art

[0002] Thermal paper is a kind of processed paper. Its manufacturing principle is to apply a layer of "thermal sensitive coating" on high-quality base paper. Although there are more than a dozen chemicals used in this color-changing layer, there are at least the following compounds: colorless dyes, which come in a wide variety, and the most commonly used are fluorescent compounds; color developers account for less than 20%, and commonly used ones are bisphenol and parahydroxybenzoic acid; sensitizers account for less than 10%, including benzenesulfonic acid amide compounds; fillers account for less than 50%, and commonly used ones are calcium carbonate (microparticles); adhesives account for less than 10%, such as polyvinyl acetate; stabilizers, such as dibenzoyl terephthalate; lubricants, etc.

[0003] When the existing thermal paper is thermally coated, the thermal coating adheres to the surface of the thermal paper and wets the thermal paper. The thermal coating needs to be dried because the thermal coating will change color at 70 degrees, causing the thermal paper to be scrapped. Therefore, long-distance transportation is generally used for drying. Therefore, we propose a coating brushing device for thermal paper production that can dry quickly. Utility Model Content
