Embodiment 1

[0037] This embodiment provides a kind of traceable adhesive tape, the specific structure is as follows figure 1 and figure 2 As shown, it includes a light-permeable substrate 1 and an adhesive layer 2 arranged in sequence. A two-dimensional code 3 is arranged on the corona surface of the light-permeable substrate 1 .

[0038] The light-permeable substrate 1 is a PET film with a thickness of 16 μm. The PET film is a single-sided corona surface, and a two-dimensional code 3 is arranged on the corona surface. The adhesive layer 2 is composited with the adhesive tape along the longitudinal direction, and is arranged on the two-dimensional code 3. The thickness of the adhesive layer 3 is 10 μm. The light transmittance of the light-transmitting substrate is 90%

[0039] The formula for preparing the adhesive layer 3 is: calculated in parts by weight, including 100 parts of polyurethane glue, 100 parts of acrylate glue, 4 parts of isocyanate curing agent, and 50 parts of organic...

Embodiment 2

[0045] This embodiment provides a kind of traceable adhesive tape, the specific structure is as follows figure 1 and figure 2 As shown, it includes a light-permeable substrate 1 and an adhesive layer 2 arranged in sequence. A two-dimensional code 3 is arranged on the corona surface of the light-permeable substrate 1 .

[0046] The light-transmissible substrate 1 is a PC film with a thickness of 6 μm. The PC film is a single-sided corona surface, and a two-dimensional code 3 is arranged on the corona surface.

Abstract

The invention provides a traceable adhesive tape. The traceable adhesive tape comprises a light-transmitting base material and an adhesive layer which are compounded with each other, the light-permeable base material comprises a first surface and a second surface which are arranged back to back; the first surface is a corona surface, and a digital printing marker is arranged on the corona surface; the first surface of the light-permeable base material is compounded with the adhesive layer. The traceable adhesive tape has the advantages of being high in recognition rate, simple in structure, high in adhesive layer adaptability and high in chemical resistance, and can be applied to industrial production and products, and tracing of production information of the products can be achieved.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, and in particular relates to a traceable adhesive tape and a preparation method thereof. Background technique [0002] In the industrial manufacturing industry, there are some raw materials, semi-finished products and finished products that need to be managed by batch number, which we collectively call materials. In all aspects of the production and processing of the enterprise, it is necessary to determine the batch number of the material. In the process of product manufacturing, it is often necessary to use adhesive tape to bond the components therein. Therefore, a traceable tape is used to realize the quality traceability management of raw materials and preparation processes in the manufacturing process of a certain batch of batches or even a specific product, which can realize the digitization and intelligence of industrial production. , and when there are product quality problems, i...
