Description

Technical Field

[0001] This invention relates to the technical field of proportioning devices for the production of swelling tape, specifically a proportioning device and proportioning method for the production of swelling tape. Background Technology

[0002] Swellable tape is mainly composed of high molecular polymers (such as rubber, polyurethane, etc.) and water-absorbing resins. It has excellent physical and chemical properties. Its swelling characteristics include rapid expansion upon contact with moisture or specific liquids, effectively filling gaps and achieving a sealing effect. Furthermore, the tape maintains stability after expansion, is not prone to aging or shrinkage with long-term use, and is adaptable to complex environments.

[0003] For example, the authorized patent with publication number CN118222204A (Composite Swellable Tape and its Preparation Method); the composite swelling tape includes a substrate layer, a barrier layer disposed on one side of the substrate layer, a base coating layer disposed on the other side of the barrier layer opposite to the substrate layer, a swelling layer disposed on the other side of the base coating layer opposite to the substrate layer, a pressure-sensitive adhesive layer disposed on the other side of the swelling layer, and a release film layer disposed on the free side of the pressure-sensitive adhesive layer. Before lamination, the base coating layer is first coated on the swelling layer and the barrier layer is first plated on the substrate layer. Then, the base coating layer and the barrier layer are laminated together at room temperature without heating and without solvents. The swelling layer is made of thermosetting polyurethane resin. This composite swelling tape ensures peel strength, product flatness and stiffness, excellent high barrier properties, and good high-temperature resistance. This invention also relates to a method for preparing the composite swelling tape.

The first motor 2 drives the stirring rod 19 to rotate through the transmission rod 17, so that the stirring rod 19 controls the mixing of the proportioned ingredients through the stirring frame 20. After the proportioning is completed, the tape material is discharged into the storage tank 6 through the first discharge head 21 for collection. After the ingredients are absorbed by the suction head 22, they are introduced into the diversion pipe 7. The second motor 25 drives the conveying roller 10 to rotate, so that the conveying roller 10 drives the tape base layer conveying wheel 9 to rotate.
