Description

technical field

[0001] The invention relates to the technical field of leather products, in particular to an environmentally-friendly water-based adhesive bonded mechanically laminated basketball. Background technique

[0002] Traditional glue bonded leather basketball (hereinafter referred to as glued basketball, please refer to the specific structure figure 1 ), from inside to outside is composed of inner tube, skeleton layer, rubber covering layer and leather 4-layer structure. The inner tube plays the role of storing gas and maintaining a certain airtightness. Wrap or wind an appropriate amount of chemical fiber fabric or yarn on the surface of the inner tube to form a skeleton layer, and then put the rubber into the mold to vulcanize into a semi-finished product—the middle tire. Grinding the surface of the middle tire > removing powder > applying solvent glue (using organic solvent to erode and swell the rubber surface), and the back of the leather is also coated w...
