Description

Technical Field

[0001] The utility model relates to the technical field of rubber products, in particular to a PVC tape which can be torn off quickly. Background Art

[0002] PVC tape is made of PVC (polyvinyl chloride) film as the base material and then coated with rubber-type pressure-sensitive adhesive. It is a tape with good continuous adhesion and has excellent insulation, pressure resistance, weather resistance, waterproofness, acid and alkali resistance, solvent resistance, etc. It can be used for pipe wrapping, anti-corrosion protection, electrical insulation, etc. It is currently widely used in wire connection, electrical insulation protection, automotive wiring and other fields.

[0003] When using PVC tape, the staff can use the sticky glue on the back of the tape to directly stick it to the interface gap, and then wrap the PVC tape around the interface gap to play a role in connection and protection.

[0004] However, when the PVC tape is wrapped, due to the high toughness of the polyvinyl chloride film itself, the staff needs to cut and use tools to cut the PVC tape. However, it is troublesome to use tools, and the staff usually tear it directly with their hands. This not only reduces the work efficiency of the staff, but also causes uneven tearing of the PVC tape, affecting the next use. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 - Figure 4 The utility model provides a technical solution: a PVC tape that can be quickly torn, including an insulating component 1, the insulating component 1 includes a polyvinyl chloride film layer 101, the outer end of the polyvinyl chloride film layer 101 is fixedly provided with an open groove 102, the open groove 102 is parallel to the front and back, the upper end of the polyvinyl chloride film layer 101 is fixedly provided with an auxiliary groove 103, the auxiliary groove 103 is located between the open grooves 102 and is parallel to the front and back, the polyvinyl chloride film layer 101 is made of polyvinyl chloride resin and other modifiers through a calendering process or a blow molding process, and the general thickness is 0.08-0.2mm, and the thickness greater than 0.25mm is called a PVC sheet. The polyvinyl chloride film layer 101 generally consists of: polyvinyl chloride film, PVC resin--40%-70%, plasticizer Agent--10%-50%, stabilizer--1%-10%, filler--1%-30%, colorant--1%-10%, the polyvinyl chloride film layer 101 is insoluble in water, alcohol, and gasoline, can swell or dissolve in ether, ketone, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons, at room temperature, it is resistant to concentrated hydrochloric acid, 90% sulfuric acid, 50%-60% nitric acid and caustic soda solution below 20%. During use, the staff uses their fingers to pinch the two ends of the polyvinyl chloride film layer 101, and then finds the tearing force point, so that the force point is distributed at the opening groove 102, and then tears it. Since the surface tension of the polyvinyl chloride film layer 101 has been destroyed by the opening groove 102, the staff is faster in the process of tearing the polyvinyl chloride film layer 101.

[0026] Furthermore, an insulating film 104 is fixedly provided at the inner end of the auxiliary groove 103. The insulating film 104 is made of materials such as polypropylene, polyimide, and polyamide, and has good insulation performance, high temperature resistance, and chemical corrosion resistance. The insulating film 104 is inside the auxiliary groove 103 and can fill the inside of the auxiliary groove 103, thereby improving the insulation of the polyvinyl chloride film layer 101.

[0027] Furthermore, an adhesive component 2 is arranged below the insulating component 1, and the adhesive component 2 includes a pressure-sensitive adhesive layer 201. The pressure-sensitive adhesive layer 201 is fixedly arranged on the lower end of the polyvinyl chloride film layer 101, and an opening groove 202 is fixedly arranged on the outer end of the pressure-sensitive adhesive layer 201. The opening groove 202 is distributed in parallel front and back, and the opening groove 202 is adapted to the opening groove 1 102. During use, the staff sticks the pressure-sensitive adhesive layer 201 to the surface of the object to be reinforced, and then wraps the polyvinyl chloride film layer 101 around the surface of the object to be reinforced.

[0028] Furthermore, the pressure-sensitive adhesive layer 201 is a complex mixture of natural rubber elastomer as the main body, with additives such as tackifying resin, softener, antioxidant, color filler and cross-linking vulcanizer. Natural rubber has high cohesive strength and elasticity, and can be well miscible with many tackifying resins, resulting in high viscosity and good wettability to the adhered material.

[0029] Working principle: During use, the staff will stick the pressure-sensitive adhesive layer 201 to the surface of the object to be reinforced, and then wrap the polyvinyl chloride film layer 101 around the surface of the object to be reinforced. After the wrapping is completed, the staff will pinch the two ends of the polyvinyl chloride film layer 101 with their fingers, find the tearing force points, distribute the force points at the opening groove 102, and then tear it. Since the surface tension of the polyvinyl chloride film layer 101 has been destroyed by the opening groove 102, the staff will be faster in the process of tearing the polyvinyl chloride film layer 101.

[0030] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
