[0015] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0016] Please refer to Figs. 1-2 The environment-friendly degradable adhesive label in the embodiment comprises a base material layer 1, and the bottom of the base material layer 1 is provided with an adhesive layer 2.
[0017] In the implementation of the example, the bottom of the adhesive layer 2 is connected with the bottom paper layer 3, a primer layer 4 for reducing the adhesion of the adhesive layer 2 is arranged between the bottom paper layer 3 and the adhesive layer 2, the bottom paper layer 3 is kraft paper, the primer layer 4 is a silicone material coating, the silicone material coating is uniformly distributed on the top of the bottom paper layer 3, the silicone material coating is more easily biodegraded, the top of the substrate layer 1 is connected with the face material layer 5, the top of the face material layer 5 is coated with the protective coating 6, the face material layer 5 is synthetic paper, a steel stamp is arranged on the top of the synthetic paper, the protective coating 6 is water-based varnish, the water-based varnish is uniformly distributed on the top of the face material layer 5, and the water-based varnish is used as the protective coating 6, which is more easily degraded than a paint-based protective coating 6.
[0018] The substrate layer 1 includes writing paper, the adhesive layer 2 is acrylic resin glue, the acrylic resin glue is uniformly coated on the bottom of the writing paper, the substrate layer 1 uses the writing paper as the substrate layer 1, the writing paper has certain flexibility and strength, can better bear other functional layers, and the relatively loose paper structure of the writing paper is favorable for penetration and adhesion of the adhesive layer 2, so that the adhesive layer 2 is firmly combined with the substrate layer 1. When the high-molecular polymer molecular chain in the acrylic resin glue contacts the surface of the adherend, the high-molecular polymer molecular chain interacts with the surface of the adherend through intermolecular forces and chemical bonding, thereby generating adhesion, and realizing adhesion of the label to the adherend.
[0019] In addition, the bottom paper layer 3 is made of kraft paper, has relatively high strength and flexibility, and can effectively protect the adhesive layer 2. The primer layer 4 is a silicone material coating, is uniformly distributed on the top of the kraft paper, and has the characteristic of low surface energy. A weak adhesion interface is formed between the adhesive layer 2 and the bottom paper layer 3, the adhesion between the adhesive layer 2 and the bottom paper layer 3 is greatly reduced, the label can be conveniently peeled off from the bottom paper layer 3 when in use, and the problems of adhesive residue or bottom paper tearing do not occur.
[0020] It should be noted that the face material layer 5 is synthetic paper, the synthetic paper has the advantages of paper and plastic film, has good printing performance and water resistance and tear resistance, a steel stamp is arranged on the top of the synthetic paper, can be used for marking important information or anti-counterfeiting marks, the protective coating 6 is water-based varnish, is uniformly distributed on the top of the synthetic paper, and forms a transparent and hard protective film after drying, protects the face material layer 5 in a physical covering manner, prevents the face material layer 5 from being rubbed, scratched, eroded by moisture and the like, and does not affect display of information on the face material layer 5.
[0021] By adopting the technical scheme, the base material layer 1 uses writing paper, and the bottom paper layer 3 uses kraft paper. The two kinds of paper materials have certain degradability in the natural environment, compared with the traditional non-degradable plastic material, the long-term pollution to the environment can be reduced. Meanwhile, the synthetic paper used for the surface material layer 5 also has the characteristics of recycling, further improving the environmental performance of the label. The selection of the overall material conforms to the environmental protection concept, which helps to reduce the generation of solid waste and reduce the pressure on the environment. The materials such as writing paper, kraft paper and synthetic paper are relatively common and low in cost, which helps to reduce the production cost while ensuring the performance of the label. Meanwhile, the water-based gloss oil and acrylic resin glue also have good cost performance.
[0022] The working principle of the above embodiment is as follows:
[0023] The environmentally friendly degradable adhesive label, when in use, the base material layer 1 serves as the main support structure, providing basic strength and stability for the entire label. The adhesive layer 2 is responsible for sticking the label to the surface of the target object, generating adhesion through contact with the object to be pasted. The bottom paper layer 3 protects the adhesive layer 2 before use, preventing it from being contaminated or prematurely failing. The primer layer 4 reduces the adhesion between the adhesive layer 2 and the bottom paper layer 3, making it easy to peel off the label from the bottom paper layer 3 when in use. The surface material layer 5 is located at the top layer, used to display printed information or patterns, while the protective coating 6 further protects the surface material layer 5, enhancing its wear resistance, water resistance and other properties, prolonging the service life of the label. The base material layer 1 uses writing paper, and the bottom paper layer 3 uses kraft paper, both of which have certain degradability in the natural environment. Meanwhile, the synthetic paper used for the surface material layer 5 also has the characteristics of recycling, further improving the environmental performance of the label.
