The invention belongs to the field of industrial filter cloths, and provides a repeatable self-adhesive tape for splicing of filter cloths and a preparation method. The base material of the reusable self-adhesive tape is a Velcro, and the Velcro has two sticking layers, one side is a fiber layer, the other side is a burr layer; the fiber layer and the burr layer are coated with a glue layer; the glue layer The layer is applied to the surface of fibers and burrs, as well as the roots of fibers and burrs to form a coating; the back of the Velcro is a hot-melt adhesive layer; when in use, the two sides of the self-adhesive tape (the fiber layer and the The back of the burr layer) is respectively pasted on the joint of the filter cloth, and then the fiber layer and the burr layer are closely attached, and the fiber and the burr are connected at the same time. , and the adhesive coating can be repeatedly bonded. |
