Description

technical field [0001] The invention relates to the technical field of hot-melt adhesives, in particular to a fluorescence-removing pressure-sensitive hot-melt adhesive for the back glue of a breathable film of a sanitary napkin and a preparation method thereof. Background technique [0002] With people's attention to health, women's sanitary napkins require good air permeability, no harmful substances such as fluorescent light, low odor, and do not affect their health. The pressure-sensitive hot melt adhesive used for sanitary napkins also needs to meet this requirement. . [0003] The traditional adhesive for sanitary napkins has poor adhesion to the breathable film, contains fluorescence, and has a strong odor. This patent mainly solves the adhesive in the hot melt adhesive for sanitary napkins, which has good adhesion to the breathable film, defluorescence, and low odor. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the f...
