Problems solved by technology

The bonding fastness between the gauze and the PE film in the cloth tape of this structure is not good, which affects the subsequent processing
Especially for the gauze with relatively sparse warp and weft threads, after the gauze and the PE film are laminated and gently rubbed with your fingers, the film will be released (that is, the gauze and the film are separated), which will have an adverse effect on subsequent processing.
If the situation is serious, it will also affect the performance of the finished tape, such as: when the tape is unrolled, the film will be peeled off, the film will be broken, the tape will not be easily torn, or the yarn on the edge of the tape will come out and produce burrs when it is torn off.
[0004] In addition, because the gauze used has a mesh-like porous structure, a relatively high amount of glue must be applied to fill the pores of the gauze when applying glue, and the adhesive tape requires a higher amount of glue to achieve good viscosity, about 100 grams per square meter, while the hot melt pressure-sensitive adhesive uses SIS and SBS as the main material, the unit price of this material is relatively high, so the cost is relatively high

Abstract

The invention discloses a duct tape and a manufacturing method thereof. Through an extrusion covering process, the duct tape is prepared by covering a first thin film layer on one surface of a base layer, covering a second thin film layer on the other surface of the base layer, coating an isolating agent on the other surface of a first thin film layer, and coating adhesive agent on the other surface of a second thin film layer. The duct tape, through covering the thin films on both surfaces of the base layer, greatly improves binding firmness between gauge and the thin film layer and eliminates a demoulding phenomenon; and meanwhile, the duct tape can avoid a corrugated edge phenomenon due to local relaxation of the gauge, and greatly reduce production cost.

Description

technical field [0001] The invention relates to a cloth-based adhesive tape and a manufacturing method thereof, in particular to a cloth-based adhesive tape coated with two layers of films and a manufacturing method thereof. Background technique [0002] The cloth base tape is based on thermal compounding of polyethylene and gauze fibers. Apply high-viscosity synthetic glue and compound with double-sided release paper. It has strong peeling force, tensile strength, grease resistance, aging resistance, temperature resistance, waterproof, and corrosion resistance. It is an insulating high-viscosity tape. Cloth tape is mainly used for carton sealing, carpet seaming, heavy binding, waterproof packaging, etc. At present, it is also frequently used in the automobile industry and the electromechanical industry. It is used in places with good waterproof measures such as automobile cabs, chassis, and cabinets, and is easy to die-cut. [0003] The structure of common cloth-based ta...
