Description

Technical Field

[0001] The utility model relates to the technical field of self-adhesive labels, in particular to a self-adhesive label which is resistant to high temperatures and not prone to breaking. Background Art

[0002] Self-adhesive labels have the advantages of no need to apply glue, paste, or dip in water, no pollution, and save labeling time compared to traditional labels. They have a wide range of applications and are convenient and fast. Self-adhesive labels are a kind of material, also called self-adhesive label material, which is made of paper, film or other special materials as the fabric, with adhesive coated on the back and silicone-coated protective paper as the base paper. It is a composite material and becomes a finished label after printing, die-cutting and other processing.

[0003] The current self-adhesive labels do not have an easy-to-tear structure, which makes it difficult for users to tear off the self-adhesive labels. In addition, they do not have the advantages of good corrosion resistance, wear resistance and flame retardancy, which reduces the service life of the self-adhesive labels and cannot meet the needs of today's market.

[0005] Although the device in the above-mentioned document can be passed, the device in the above-mentioned document cannot be used in a high-temperature environment. The current self-adhesive labels are usually made of paper, film or other special materials. They are easily damaged by heat when used in a high-temperature environment, making the information on the self-adhesive label difficult to read, affecting the integrity of the self-adhesive label. In addition, the edges of the self-adhesive label are prone to warping during use, and the degree of warping changes with the length of use, which in turn causes the self-adhesive label to fall off, making the product information unable to be identified. Utility Model Content

[0006] The purpose of the utility model is to provide a high-temperature resistant and non-breakable self-adhesive label, so as to solve the problem in the background art that the self-adhesive label warps and affects the use effect in a high-temperature environment.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0013] The above technical solution is adopted, in which the high temperature resistant layer is made of polytetrafluoroethylene, and combined with the flame retardant layer, the label body can be used in a high temperature environment, further increasing the high temperature resistance effect of the adhesive layer.

[0014] A further improvement of the technical solution of the present invention is that the flame retardant layer is arranged in a corrugated shape, an inner cavity is opened on the inner side wall of the flame retardant layer, and the interior of the inner cavity is filled with an inert gas.

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below with reference to the embodiments:

[0035] Example 1

[0036] like Figure 1 、 Figure 5 and Figure 6As shown, the utility model provides a self-adhesive label that is resistant to high temperatures and not easy to break, including a roll core 1; a base paper 2 is detachably connected to the outer wall of the roll core 1, a label body 3 is provided on the side of the base paper 2 away from the roll core 1, and an adhesive layer 7 is provided on the side of the label body 3 close to the base paper 2, a cavity 17 is symmetrically provided on one side of the adhesive layer 7, a drainage plate 18 is fixedly connected to the bottom of the inner side wall of the cavity 17, a permeable net 16 is symmetrically provided on one side of the adhesive layer 7, and a reinforcing sheet 15 is provided on the surface of the permeable net 16 and the cavity 17, a plurality of holes are provided on the surface of the permeable net 16, the drainage plate 18 is arranged in an arc shape, and the curvature of the drainage plate 18 tends to increase, and the interior of the cavity 17 is filled with pressure-sensitive adhesive.

[0037] In this embodiment, since the self-adhesive label may warp due to the high external temperature during use, the surface information thereof may also be damaged at different levels, making the information on the surface of the self-adhesive label difficult to read.

[0038] The cavity 17 on the surface of the adhesive layer 7 is filled with pressure-sensitive adhesive. The cavity 17 is rectangular and distributed at the edge of the adhesive layer 7. Specifically, the reinforcing sheet 15 arranged on the surface of the cavity 17 is provided with a number of small holes. During use, the label body 3 is removed and the adhesive layer 7 is pasted on the product surface. At this time, the cavity 17 can be pressed, and the pressure-sensitive adhesive inside it flows along the curvature of the drainage plate 18 under the extrusion force. The pressure-sensitive adhesive acts on the surface of the reinforcing sheet 15 through the permeable net 16, thereby increasing the adhesive effect of the adhesive layer 7, reducing the possibility of warping of the label body 3 during use, and improving the display effect of the label body 3.

[0039] Example 2

[0040] like Figure 2 and Figure 3 As shown, based on Example 1, the utility model provides a technical solution: preferably, an anti-fracture layer 6 is provided on the side of the adhesive layer 7 away from the reinforcing plate 15, a flame retardant layer 5 is provided on one side of the anti-fracture layer 6, a high-temperature resistant layer 4 is provided on one side of the flame retardant layer 5, the flame retardant layer 5 is provided in a corrugated shape, an inner cavity 8 is provided on the inner wall of the flame retardant layer 5, and the interior of the inner cavity 8 is filled with inert gas.

[0041] In this embodiment, the flame retardant layer 5 is corrugated and the inner cavity 8 at the middle position is filled with inert gas. The flame retardant layer 5 is made of polyethylene terephthalate film material, and the high temperature resistant layer 4 is made of polytetrafluoroethylene. With the cooperation of the two, the label body 3 can be used in a high temperature environment, and the high temperature resistance effect of the adhesive layer 7 is further increased, thereby solving the problem of the label body 3 warping due to the high external environment temperature.

[0042] Example 3

[0043] like Figure 4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a cross fixing bar 9 is fixedly connected at the middle position of the anti-fault layer 6, and a limiting column 10 is symmetrically installed inside the anti-fault layer 6. The outer wall of the limiting column 10 is sleeved with an elastic pull rope 11, and the end of the elastic pull rope 11 away from the limiting column 10 is fixedly connected to the limiting block 12. A plurality of arc plates 13 are fixedly connected to the inside of the anti-fault layer 6, and an arc groove 14 is opened at the middle position of the arc plate 13. The elastic pull rope 11 and the limiting block 12 are an integrated structure, the elastic pull rope 11 is an elastic structure, the elastic pull rope 11 is installed through the inside of the arc plate 13, and the limiting block 12 and the arc plate 13 are slidably connected.

[0044] In this embodiment, the label body 3 itself will be bent during use, causing it to suffer varying degrees of damage, and further causing it to be at risk of breaking during use. The limiting columns 10 are fixed at the four corners inside the anti-fault layer 6. The limiting columns 10 have a small degree of telescopic performance, and the elastic pull rope 11 is elastic. When the label body 3 is deformed, the elastic pull rope 11 can make corresponding extension or contraction with the deformation arc of the label body 3. It can adjust its own angle under the action of the arc plate 13, the arc groove 14 and the limit block 12. The arc plate 13 and the cross fixing bar 9 can increase the overall strength of the anti-fault layer 6, further reducing the possibility of the label body 3 breaking due to deformation during use.

[0045] The working principle of the high temperature resistant and non-breakable self-adhesive label is described in detail below.

[0046] like Figures 1-6As shown, first remove the label body 3 from the surface of the base paper 2 and stick it on the surface of the product. The label body 3 will be bent during use, causing it to be damaged to varying degrees, which in turn causes it to be at risk of breaking during use. The limiting columns 10 are fixed at the four corners inside the anti-fracture layer 6. The limiting columns 10 have a small degree of telescopic performance, and the elastic pull rope 11 is elastic. When the label body 3 is deformed, the elastic pull rope 11 can make corresponding extension or contraction with the deformation curvature of the label body 3. It can adjust its own angle under the action of the arc plate 13, the arc groove 14 and the limit block 12, wherein the arc plate 13 and the cross fixing bar 9 can increase the overall strength of the anti-fault layer 6. The flame retardant layer 5 is corrugated and the inner cavity 8 in the middle position is filled with inert gas. The flame retardant layer 5 is made of polyethylene terephthalate film material, and the high-temperature resistant layer 4 is made of polytetrafluoroethylene. With the cooperation of the two, the label body 3 can be used in a high-temperature environment, and the high-temperature resistance effect of the adhesive layer 7 is further increased. After being pasted on the surface of the product, the cavity 17 is pressed, and the pressure-sensitive adhesive inside it flows along the curvature of the drainage plate 18 under the extrusion force. The pressure-sensitive adhesive passes through the permeable net 16 and acts on the surface of the reinforcement sheet 15, thereby increasing the adhesive effect of the adhesive layer 7 and reducing the possibility of warping of the label body 3 during use.

[0047] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
