Description

TECHNICAL FIELD

[0001] The utility model relates to tire tread label technical field especially relates to a novel anti -warping and anti -adhesion tire tread label. BACKGROUND

[0002] With the continuous expansion of tire production capacity, the consumption of supporting tread labels presents a synchronous growth trend. However, in the storage management link of the tread labels, affected by seasonal climate characteristics, the label storage quality faces double challenges: on the one hand, the humidity fluctuation in plum rain season causes the paper-based material to absorb moisture and deform, leading to edge warping problems; on the other hand, the high temperature environment in summer accelerates the softening of the hot melt adhesive, causing overflow and adhesion between adjacent labels.

[0003] Such problems not only seriously restrict the continuous operation efficiency of the tire labeling process, but also cause some finished product tread labels to be scrapped due to glue stain pollution or adhesion damage.

[0004] After searching, the patent technology of patent number CN219085583U uses the process of laminating the label base paper to solve the warping problem of the label. Although this process is effective, the high cost of lamination will greatly increase the material cost of the label, and at the same time, the lamination process will inevitably produce new drawbacks in production: the base paper must be treated with adhesion coating (which will additionally increase the coating process cost) or electric spark impact (which cannot be stored for a long time after treatment, and the corona value will continue to decay, resulting in local paper film delamination of the product). The above-mentioned situation will greatly increase the use cost of the label and greatly increase the label defect rate.

[0005] The patent technology of patent number CN219085583U can only solve the warping problem of the label, and cannot solve the overflow and adhesion of the label caused by the softening of the adhesive in summer high temperature.

[0006] Based on this, a novel anti-warping and anti-adhesion tire tread label is proposed. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims at solving the problems in the prior art and provides a novel anti-warping and anti-adhesion tire tread label.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0009] A novel anti-warping and anti-adhesion tire tread label, comprising a face material layer, a glue layer and a base paper layer connected in sequence, wherein the side of the base paper layer away from the glue layer is provided with a first silicon oil layer.

[0010] Preferably, the side of the base paper layer in contact with the glue layer is provided with a second silicon oil layer.

[0011] Preferably, the face material layer adopts one of aluminized Pet, synthetic paper and copper-aluminum composite paper, and the thickness is between 0.02-0.1mm.

[0012] Preferably, the glue layer adopts rubber type hot melt glue, and the coating gram weight is 25-80g / m2.

[0013] Preferably, the base paper layer adopts glassine base paper, CCK base paper or wood pulp paper, and the gram weight is 40-200g / m2.

[0014] Preferably, the thickness of the first and second silicon oil layers is between 0.1-300um.

[0015] Compared with the prior art, the beneficial effects of the present application are:

[0016] The present application coats a layer of anti-sticking silicon oil with a thickness between 0.1-300um on the outer surface of the label base paper, uses the economy, simple coating process, water resistance and anti-sticking property of the anti-sticking silicon oil, solves the problems of label curling and sticking, and the increase in use cost is negligible. Since the silicon oil coating has no special requirements for the thickness, no new defects and losses are generated in quality control, and the problems of high cost of anti-curling in the prior art and the label sticking caused by the softening of the adhesive in summer high temperature are solved. BRIEF DESCRIPTION OF DRAWINGS

[0018] In the figure: 1, face material layer; 2, glue layer; 3, second silicon oil layer; 4, base paper layer; 5, first silicon oil layer. DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0020] Referring to Figure 1 A novel anti-curling and anti-sticking tire tread label includes a face material layer 1, a glue layer 2 and a base paper layer 4 connected in sequence, and the base paper layer 4 is provided with a first silicon oil layer 5 away from the glue layer 2.

[0021] The label in use, through the outer surface of the label base paper, coated with a thickness of 0.1-300um of anti-sticking silicon oil, using the economy of anti-sticking silicon oil, the simplicity of coating process, the waterproofness of silicon oil, the anti-sticking of silicon oil, at the same time solves the anti-warping and anti-sticking problem of tire tread label, and the increase in use cost is negligible, and because the silicon oil coating has no special requirements for its thickness, it will not produce new defects and new losses in quality control, solving the problem of high cost of anti-warping in the prior art, and the problem of label overflow and sticking caused by the softening of the adhesive in high temperature in summer

[0022] In this embodiment, the second silicon oil layer 3 is provided on the side of the base paper layer 4 in contact with the glue layer 2, and the design of the second silicon oil layer 3 facilitates the separation of the base paper layer 4 from the glue layer 2. The double-sided silicon oil coating of the base paper layer 4, i.e. the synchronous coating of the first silicon oil layer 5 and the second silicon oil layer 3, can improve production efficiency and further reduce cost (this efficiency improvement scheme requires the installation of a coating device on the original standard coating machine).

[0023] In this embodiment, the face material layer 1 is made of one of aluminized Pet, synthetic paper and copper-aluminum composite paper, and the thickness is between 0.02-0.1mm. The three kinds of face materials each have different advantages: aluminized Pet face material is suitable for small tires such as passenger car tires, and has better conformability; synthetic paper face material is suitable for larger tires such as truck tires, and has better flatness; copper-aluminum composite paper face material is less prone to static electricity when manually labeling, and is relatively thick, so it has better labeling efficiency.

[0024] In this embodiment, the glue layer 2 is made of rubber type hot melt adhesive, and the coating weight is 25-80g / m2. The rubber type adhesive is more compatible with the body material of the tire, making the label and the tire more stable in the later stage of adhesion.

[0025] In this embodiment, the base paper layer 4 is made of glassine base paper, CCK base paper or wood pulp paper, and the grammage is 40-200g / m2. The die cutting process of tire label is high speed die cutting. Because the adhesive is sticky, a sharp knife with high grade is needed. Glassine base paper, CCK base paper and wood pulp paper have strong density and are not prone to edge damage in the die cutting process of tire tread label.

[0026] In the embodiment, the thickness of the first silicone oil layer 5 and the second silicone oil layer 3 is between 0.1-300 um, and the anti-winding and anti-adhesion effect of the silicone oil layer on the tire label is mainly achieved by using the waterproof and anti-adhesion properties of the silicone oil layer itself. The silicone oil layer has wide compatibility with the coating thickness, and the thickness of 0.1-300 um can achieve the anti-winding and anti-adhesion effect described in the application, and the thickness range is compatible with the coating thickness of the conventional coating machine coating roller on the market, without the need for additional customization of the coating roller, further saving the cost.

[0027] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
