Description

Technical Field

[0001] The utility model relates to the technical field of plastic stickers, in particular to a tear-resistant PVC plastic sticker. Background Art

[0002] PVC plastic stickers are a widely used plastic product. The Chinese name of PVC is polyvinyl chloride. Polyvinyl chloride has excellent waterproof and adhesive properties. Plastic stickers made of polyvinyl chloride, however, the existing tear-resistant PVC plastic stickers still have defects, such as:

[0003] When stickers are pasted on the surface of objects, due to the diversity of the surface shapes of the objects, stickers are prone to sliding, bubbles, wrinkles and other problems during the process of affixing, causing inconvenience in the use of the stickers.

[0004] For example, a privacy sticker with publication number CN112226170B has an elastic polymer layer on the upper or lower part of the printed layer to prevent it from being pushed. Even if it is pushed or pulled with fingers, the force can be consumed in deforming and stretching the elastic polymer layer, thereby solving the problem of sliding at the pasting position in the prior art.

[0005] The above-mentioned privacy sticker improves its structure so that it is not easily moved by external forces when pulled or touched. However, since it is provided with an elastic polymer layer, it is more likely to generate bubbles and wrinkles when it is attached to the surface of a complex object. Utility Model Content

[0006] The purpose of the present invention is to provide a tear-resistant PVC plastic sticker to solve the problem of bubbles and wrinkles being more likely to be generated when the sticker is attached to the surface of a complex object, as mentioned in the background art.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a tear-resistant PVC plastic sticker, comprising a PVC base layer, a connecting layer and a tear-resistant layer, the PVC base layer being located in the middle part of the PVC plastic sticker, and the upper end of the PVC base layer being pasted with a connecting layer, the upper surface of the connecting layer being pasted with a tear-resistant layer, and the upper surface of the tear-resistant layer being adhered to the flame-retardant layer through the connecting layer, and the upper end of the flame-retardant layer being pasted with an antioxidant layer.

[0008] Furthermore, the tear-resistant layer has two layers symmetrically arranged with respect to the PVC base layer, and the connecting layers adhered to the upper and lower surfaces of the tear-resistant layer are made of silicone.

[0009] Furthermore, the tear-resistant layer is composed of PVC strips and PET strips, and the PVC strips and the PET strips are arranged in an interlaced manner up and down, and the PVC strips and the PET strips are staggered and distributed at an angle of 45 degrees with respect to the tear-resistant layer.

[0010] Furthermore, the upper surface of the flame retardant layer is staggeredly provided with first depressions and first protrusions, the flame retardant layer is made of glass fiber, and the flame retardant layer has two layers symmetrically arranged with respect to the PVC base layer.

[0011] Furthermore, the lower surface of the anti-oxidation layer is alternately provided with second recesses and second protrusions, and the first recesses and the second protrusions form an engaging structure.

[0012] Furthermore, an adhesive layer is adhered to the lower surface of the flame retardant layer below the PVC base layer, and the lower surface of the adhesive layer is wavy. The adhesive layer is made of silicone, and adhesive is fixed below the adhesive layer.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The tear-resistant PVC plastic sticker is provided with a tear-resistant layer. The tear-resistant layer is composed of PVC strips and PET strips interlaced up and down. The PET material has high strength, which can provide the PVC plastic sticker with tear-resistant properties. At the same time, due to the structural characteristics of the tear-resistant layer, its structure can also provide the PVC plastic sticker with the property of resisting tearing in all directions.

[0015] Furthermore, an adhesion layer is provided, which is made of silicone and has a wavy lower surface. When the adhesive layer is attached to an uneven surface of an object, the residual air will flow out from the depressions in the adhesion layer, making the PVC plastic sticker fit the surface of the object better.

[0016] Furthermore, the flame retardant layer and the anti-oxidation layer are connected by an intermeshing structure, which provides a certain support force for the anti-oxidation layer and prevents the sticker from being damaged due to friction. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 1: Please refer to Figure 1-Figure 5 The utility model provides the following technical solution: a tear-resistant PVC plastic sticker, comprising a PVC base layer 1, a connecting layer 2, and a tear-resistant layer 3, wherein the PVC base layer 1 is located in the middle of the PVC plastic sticker, and the connecting layer 2 is adhered to the upper end of the PVC base layer 1, the tear-resistant layer 3 is adhered to the upper surface of the connecting layer 2, and the upper surface of the tear-resistant layer 3 is adhered to the flame-retardant layer 6 through the connecting layer 2, and the upper end of the flame-retardant layer 6 is adhered to the anti-oxidation layer 11;

[0025] The tear-resistant layer 3 is symmetrically arranged with two layers about the PVC base layer 1, and the connecting layer 2 adhered to the upper and lower surfaces of the tear-resistant layer 3 is composed of silicone. The tear-resistant layer 3 is composed of PVC strips 4 and PET strips 5, and the PVC strips 4 and PET strips 5 are staggered and interspersed up and down, and the PVC strips 4 and PET strips 5 are staggered at a 45-degree angle. When using the tear-resistant PVC plastic sticker, the PVC plastic sticker is provided with a tear-resistant layer 3, and the tear-resistant layer 3 is composed of PVC strips 4 and PET strips 5 staggered and interspersed up and down, and the PVC strips 4 and PET strips 5 are staggered at a 45-degree angle with respect to the tear-resistant layer 3. Due to the high strength of the PET material, the PVC plastic sticker is not easily damaged, and the special structure of the tear-resistant layer 3 also provides the PVC plastic sticker with tear-resistant properties in all directions;

[0026] The upper surface of the flame retardant layer 6 is staggered with a first depression 7 and a first protrusion 8, and the flame retardant layer 6 is made of glass fiber, and the flame retardant layer 6 is symmetrically arranged with two layers about the PVC base layer 1. The lower surface of the anti-oxidation layer 11 is staggered with a second depression 9 and a second protrusion 10, and the first depression 7 and the second protrusion 10 form a meshing structure. The lower surface of the flame retardant layer 6 below the PVC base layer 1 is adhered with an adhesive layer 12, and the lower surface of the adhesive layer 12 is wavy. The adhesive layer 12 is made of silicone, and an adhesive 13 is fixed below the adhesive layer 12. The flame retardant layer 6 is meshed with the adhesive layer 13. The structure is connected to the anti-oxidation layer 11, which provides a certain support for the outer surface of the PVC plastic sticker, prevents the PVC plastic sticker from being damaged due to friction, and improves the service life of the PVC plastic sticker. When pasting, the adhesion layer 12 first contacts the surface of the object. Since the adhesion layer 12 is made of silicone, it is easier to adhere to the complex surface of the object. At the same time, since the lower surface of the adhesion layer 12 is wavy, the air between the object and the PVC plastic sticker can be discharged from the depression when adhering to the surface of the object, reducing the generation of bubbles and making the PVC plastic sticker adhere closely to the surface of the object.
