Description

Technical Field

[0001] The utility model relates to the field of paper printing, in particular to a high-temperature resistant label paper. Background Art

[0002] High-temperature resistant label paper plays an extremely important role in modern industry, logistics, medical care, aerospace and other fields. Different industries have different demands for high-temperature resistant label paper, such as temperature resistance range, material, viscosity, chemical resistance, etc. There are many types of high-temperature resistant label paper on the market that can meet the diverse needs in different scenarios.

[0003] A search revealed that in the prior art, Chinese patent publication number CN212181797U discloses "a label paper that can be used to fill in the promotional price of a promotional activity, and then the label paper covers the original price. When the promotion is over, the face paper and pearlescent film of the label paper are peeled off, and the remaining transparent film is pasted over the original price. The original price can be seen through the transparent film, eliminating the need to waste costs by pasting new expression paper and the unsightly situation of multiple labels being superimposed and pasted." However, the following defects still exist:

[0004] (1) However, when using multiple glue layers, the glue may melt easily in a high temperature environment, resulting in the label paper not being firmly attached;

[0005] (2) At the same time, the overall structure of the label is relatively simple, resulting in a short lifespan of the label and being easily affected by oxidation from the external environment.

[0006] Therefore, we have made improvements to this and proposed a high-temperature resistant label paper. Utility Model Content

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0034] See Figures 1 to 6 , the utility model provides a technical solution:

[0035] A high-temperature resistant label paper includes a substrate 1, a label paper body 2 is arranged on the surface of the substrate 1, the label paper body 2 adopts a multi-layer structure and the bottom layer is a base paper 3, and the label paper body 2 is provided with the base paper 3, a reinforcement layer 4, an adhesive layer 5, an insulation layer 6, a protective layer 7 and a printing layer 8 from bottom to top.

[0036] Specifically, such as Figure 3 As shown, the bottom paper 3 is the bottom layer and is made of glassine release paper material. The bottom paper 3 is used to effectively support the entire label paper body 2 structure to prevent the label paper body 2 from bending or curling during processing.

[0037] Specifically, such as Figure 3 As shown, the reinforcement layer 4 is arranged on the outer layer of the base paper 3. The reinforcement layer 4 is made of polyimide film material to make the label paper body 2 have extremely high thermal stability and chemical corrosion resistance.

[0038] Specifically, such as Figure 3 As shown, the adhesive layer 5 is arranged on the outside of the reinforcement layer 4. The adhesive layer 5 adopts a permanent acrylic pressure-sensitive adhesive material. The adhesive layer 5 can still maintain good adhesion at high temperatures, ensuring that the label paper body 2 can be firmly adhered to the surface of various materials and is not easy to fall off.

[0039] Specifically, such as Figure 3 As shown, the heat insulation layer 6 is provided on the outer layer of the adhesive layer 5. The heat insulation layer 6 is made of ceramic fiber paper material. The heat insulation layer 6 is used to prevent heat from being directly transferred to the inside of the label, thereby protecting the stability of the label in a high temperature environment.

[0040] Specifically, such as Figure 3 As shown, the protective layer 7 is arranged on the outside of the heat insulation layer 6. The protective layer 7 is made of polyester film material. The protective layer 7 can effectively protect the label paper body 2 from damage by the external environment while maintaining the clarity and readability of the label paper body 2.

[0041] Specifically, such as Figure 3 As shown, the printing layer 8 is arranged on the outermost layer of the label paper body 2. The printing layer 8 selects ink and printing method according to specific needs to ensure that the label paper body 2 can still maintain clear text and patterns in a high temperature environment.

[0042] By setting the base paper 3, the reinforcement layer 4, the adhesive layer 5, the thermal insulation layer 6, the protective layer 7 and the printing layer 8, during use, the base paper 3 adopts glassine release paper, which has a dense and uniform texture and has good internal strength and light transmittance. The reinforcement layer 4 adopts polyimide film, which has extremely high thermal stability and chemical corrosion resistance and can withstand temperatures above 300°C. The permanent acrylic adhesive can still maintain good viscosity at high temperatures, and also has good chemical resistance and oxidation resistance, and can maintain stable performance in harsh environments. The ceramic fiber paper has good high temperature resistance and thermal insulation performance, which can effectively improve the high temperature resistance of the label paper body 2. The polyester film has excellent high temperature resistance and can also resist the erosion of chemical substances. Using high temperature resistant ink for printing can ensure that the label paper body 2 will not fade or blur in a high temperature environment.

[0043] Specifically, when using this high-temperature resistant label paper: directly tear off the label paper body 2 from the surface of the substrate 1. Since the label paper body 2 adopts a variety of composite materials, it can effectively support the entire label paper body 2 structure and prevent the label paper body 2 from bending or curling during processing. It can also maintain stability in high-temperature environments, is not easy to deform or melt, and has good resistance to chemical substances such as flux and melting agents. The permanent acrylic pressure-sensitive adhesive has good chemical resistance and oxidation resistance, and can maintain stable performance in harsh environments. Ceramic fiber paper can effectively improve the high-temperature resistance of the label paper body 2. This high-temperature resistant label paper fully utilizes the high-temperature resistance and advantages of each layer of material through a combination of multi-layer structures, thereby achieving stable use in high-temperature environments.
