Description

Technical Field

[0001] The utility model relates to the technical field of coating rollers, in particular to a coating roller for water-based pressure-sensitive adhesive. Background Art

[0002] Water-based pressure-sensitive adhesive is a type of adhesive that is sensitive to pressure and has high peel force and peel strength. It is suitable for bonding materials such as foam and paper. When the temperature of the pressure roller is too high, the intermolecular force of the adhesive will be reduced, and the molecules will easily lose their "constraints", resulting in a "high-temperature glue flow" phenomenon. When the temperature is too low, it will affect the adhesion shape, thereby reducing the processing quality. Therefore, it is particularly important to control the temperature of the pressure roller surface.

[0003] However, the existing equipment does not have a coating roller for real-time temperature monitoring. When the temperature of the coating roller is too high, it cannot be immediately known by relevant personnel, which will affect the coating quality. Therefore, a coating roller for water-based pressure-sensitive adhesive is proposed. Utility Model Content
