Description

Technical Field

[0001] The utility model belongs to the technical field of label paper, and more specifically relates to a high-temperature resistant hot-melt pressure-sensitive adhesive label paper. Background Art

[0002] High temperature resistant labels are one of the most widely used special labels. The application industries of high temperature resistant labels are also very wide, and the applications of various high temperature labels are also different. Generally speaking, they are more widely used in the automotive industry, electronic commerce, manufacturing industry, and steel industry. For example, automobile engine labels, automobile compressor labels, automobile generator labels, PCB motherboard labels, steel labels, aviation labels, etc. all require special labels with high temperature resistance, but the degree of high temperature resistance is different.

[0003] Some of the current label papers are used in high temperature environments for a long time. Due to thermal expansion and contraction, they are prone to bulging, which can cause the label paper to fall off.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-temperature resistant hot-melt pressure-sensitive adhesive label paper is provided to achieve the purpose of having more practical value. Utility Model Content

[0005] In order to solve the above technical problems, the present invention provides a high temperature resistant hot melt pressure sensitive adhesive label paper, which is achieved by the following specific technical means:

[0006] A high-temperature resistant hot-melt pressure-sensitive adhesive label paper comprises a base paper layer, an adhesive layer is connected to the lower surface of the base paper layer, a plurality of heat dissipation grooves are provided in the base paper layer, a plurality of through grooves are provided at the bottom of the heat dissipation grooves, an ink layer is provided on the upper surface of the base paper layer, the upper surface of the ink layer is covered with a corrosion-resistant layer, and a release paper layer is connected to the lower surface of the adhesive layer.

[0007] Furthermore, the adhesive layer is made of pressure-sensitive adhesive material.

[0008] Furthermore, the base paper layer is made of thermal paper.

[0009] Furthermore, the corrosion-resistant layer is made of polyester film.

[0010] Furthermore, the heat dissipation grooves are evenly distributed in the base paper layer, and the through grooves are evenly distributed at the bottom of the heat dissipation grooves.

[0011] Furthermore, the top of the through groove is communicated with the top of the heat dissipation groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Through the coordinated use of the heat dissipation slots and the through slots, the heat dissipation slots and the through slots can increase the heat dissipation effect of the base paper layer in a high temperature environment. At the same time, the gap formed by the heat dissipation slots and the through slots can prevent the label paper from bulging due to thermal expansion and contraction, which would cause the label paper to be unable to be used normally.

[0014] Through the use of corrosion-resistant layer, the corrosion-resistant layer is made of polyester film. Polyester film has high tensile strength and impact strength, which makes it not easy to break and deform. It also has good chemical resistance and can resist the erosion of organic acids, alkalis, salts, etc. It can also withstand high temperatures and is not easy to deform or damage. It can maintain its characteristics when heated for a long time at high temperatures or at low temperatures. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example:

[0025] As attached Figure 1 To the attached Figure 4 As shown:

[0026] The utility model provides a high-temperature resistant hot-melt pressure-sensitive adhesive label paper, comprising a base paper layer 1, the lower surface of the base paper layer 1 is connected to an adhesive layer 2, a plurality of heat dissipation grooves 101 are provided in the base paper layer 1, and a plurality of through grooves 102 are provided at the bottom of the heat dissipation grooves 101, an ink layer 3 is provided on the upper surface of the base paper layer 1, the upper surface of the ink layer 3 is covered with a corrosion-resistant layer 4, and the lower surface of the adhesive layer 2 is connected to a release paper layer 5.

[0027] Among them, the adhesive layer 2 is made of pressure-sensitive adhesive material, which has high reliability. In various harsh environments, such as high temperature, low temperature, humid or dry conditions, the pressure-sensitive adhesive can maintain stable adhesion to ensure that the adhered items are firm and reliable.

[0028] The base paper layer 1 is made of thermal paper, which can withstand friction and external impact and is durable.

[0029] Among them, the corrosion-resistant layer 4 is made of polyester film. The polyester film has high tensile strength and impact strength, which makes it not easy to break and deform. It also has good chemical resistance and can resist the erosion of organic acids, alkalis, salts, etc. It can also withstand high temperatures and is not easy to deform or damage. It can still maintain its characteristics when heated for a long time at high temperatures or at low temperatures.

[0030] Among them, the heat dissipation grooves 101 are evenly distributed in the base paper layer 1, and the through grooves 102 are evenly distributed at the bottom of the heat dissipation grooves 101. The gap formed by the heat dissipation grooves 101 and the through grooves 102 can prevent the label paper from bulging due to thermal expansion and contraction, which makes the label paper unable to be used normally.

[0031] The top of the through groove 102 is connected to the top of the heat dissipation groove 101 . The heat dissipation groove 101 and the through groove 102 can increase the heat dissipation effect of the base paper layer 1 in a high temperature environment.

[0032] The working principle of this embodiment is as follows:

[0033] Through the coordinated use of the heat dissipation groove 101 and the through groove 102, the heat dissipation groove 101 and the through groove 102 can increase the heat dissipation effect of the base paper layer 1 in a high temperature environment. At the same time, the gap formed by the heat dissipation groove 101 and the through groove 102 can prevent the label paper from bulging due to thermal expansion and contraction, which makes the label paper unable to be used normally. Through the use of the corrosion-resistant layer 4, the corrosion-resistant layer 4 is made of polyester film. The polyester film has high tensile strength and impact strength, which makes it not easy to break and deform. It also has good chemical resistance and can resist erosion by organic acids, alkalis, salts, etc. It can also withstand high temperatures, is not easy to deform or damage, and can maintain its characteristics when heated for a long time at high temperatures or at low temperatures.
