Description

Technical Field

[0001] The invention belongs to the technical field of adhesive preparation, and in particular relates to a preparation method and application of a high-adhesion adhesive for nuclide removal. Background Art

[0002] With increasingly stringent environmental regulations and continuous advancement of new materials technology, adhesives, as a key functional material, are rapidly developing in the direction of green environmental protection, high performance and intelligence, especially in frontier fields such as nuclear safety, new energy, electronic manufacturing and sustainable development. They show great potential for application. For the efficient removal of radionuclides on the surface of objects, traditional physical and chemical methods, such as ultrasonic cleaning and conventional chemical detergents, are widely used, but they are difficult to meet the needs of deep decontamination of complex surfaces and fine structures. These traditional methods not only have limited adaptability to diverse substrates and low ability to adsorb and capture radionuclides, but also easily cause secondary pollution during use, posing a threat to the environment and human health, greatly restricting their effectiveness and promotion in high-standard nuclear safety scenarios.

[0003] In contrast, adhesives, relying on their excellent adhesion properties and high surface adaptability, can be evenly coated and tightly adhered to complex, irregular or even micro-nanostructured surfaces. Through physical adsorption and chemical bonding, they can effectively capture and fix radionuclide ions, greatly improving the interface with pollutants. This material not only shows significant radionuclide removal efficiency in practical applications, but also has the advantages of simple operation, low secondary pollution risk and good environmental compatibility. Therefore, adhesives are becoming a research and application hotspot in the field of surface radionuclide removal. However, currently commercially available or ordinary adhesives often only have good adsorption properties for a small number of specific radionuclides, making it difficult to adapt to the actual needs of nuclear safety and efficient purification. At the same time, they cannot take into account the organic unity of high strength, high elasticity and high selectivity. Problems such as loss of adsorption efficiency and deformation ability and low tensile strength often occur in dry environments, which greatly limits their wide application in extreme or special scenarios. Summary of the invention

[0004] An object of the present invention is to solve at least the above problems and / or disadvantages and to provide at least the advantages which will be described hereinafter.

[0005] In order to achieve these objects and other advantages of the present invention, a method for preparing a high-adhesion adhesive for nuclide removal is provided, comprising the following steps:

[0081] Comparative Example 2

[0082] This comparative example provides a low-adhesion polymer material, which is mainly different from Example 1 in that it only has low adhesion. The preparation method includes the following steps:

[0084] Step 2: Add 0.05 g of sodium benzoate, 2 g of sodium dodecylbenzenesulfonate, 1 g of glycerol, 10 g of acetic anhydride, and 0.01 g of pigment to 100 g of polyvinyl alcohol and stir until the color is uniform to prepare a polyvinyl alcohol solution;

[0086] Application Example 1

[0087] Measurement of the peel strength of the highly adhesive adhesives prepared in Examples 1-5 and the materials prepared in Comparative Examples 1-2 after 20 adhesion-peel cycles on pigskin. The specific operation method is as follows: Before the test, the pigskin is heat-treated at 37 °C to simulate the human body temperature, and then the highly adhesive adhesives prepared in Examples 1-5 and the materials prepared in Comparative Examples 1-2 are respectively attached to the pigskin. In the experiment, a universal material testing machine is used to perform peel tests at a constant peel angle of 90° and a peel speed of 50 mm / min, and the peel force is recorded.

[0088] Figure 5 The peel strength of the highly adhesive adhesives prepared in Examples 1-5 and the materials prepared in Comparative Examples 1-2 after 20 adhesion-peel cycles on pigskin. From Figure 5 It can be seen that the adhesive materials prepared in Examples 1-5 and the adhesive material prepared in Comparative Example 1 have similar peel strengths, indicating that they have similar adhesion properties; while the peel strength of the polymer material prepared in Comparative Example 2 is much lower than that of other samples, indicating that it has relatively poor adhesion performance. This is because the introduced acetic anhydride converts some hydroxyl groups into hydrophobic groups.

[0089] Application Example 2

[0090] Measurement of the removal performance of the highly adhesive adhesives prepared in Examples 1-7 and the materials prepared in Comparative Examples 1-2 on radionuclides on the surface of pigskin. The specific operation method is as follows: The excised pigskin is cut into rectangular samples, and a rectangular pollution area of 5×5 cm 2 is defined, and the remaining part is kept clean for safe operation of the pigskin samples with tweezers. At the beginning of the experiment, 100 μL of uranium solution is quickly and evenly applied to the designated area of each sample using a pipette, and 50 μL is applied to each pigskin sample. After natural drying for a period of time, equal amounts of the adhesives prepared in Examples 1-5 and the materials prepared in Comparative Examples 1-2 are evenly applied to the surface of the pigskin. After acting for a period of time, the corresponding samples are removed, and then the remaining radioactive contamination level is measured.

[0091] Figure 6 The removal efficiency of the highly adhesive adhesive prepared in Example 1 and the materials prepared in Comparative Examples 1-2 on radionuclides on the surface of pigskin. From Figure 6 It can be seen that compared with Example 1, in Comparative Example 1, due to the absence of plant polyphenols and the lack of the chelating effect of plant polyphenols on radionuclides, the radionuclide removal efficiency of Comparative Example 1 decreases; in Comparative Example 2, due to the introduction of acetic anhydride converting some hydroxyl groups into hydrophobic groups, the adhesion of the material is reduced, so the radionuclide removal efficiency of Comparative Example 2 decreases; the radionuclide removal efficiencies of Comparative Example 1 and Comparative Example 2 decrease in turn, further indicating that the adhesion performance of the adhesive and the chelating effect of plant polyphenols can synergistically promote the removal of radionuclides on the surface and interface of the substrate.

[0092] Figure 7The nuclide removal efficiency of the highly adhesive adhesives prepared in Examples 1-5 and the materials prepared in Comparative Examples 1-2 on the surface of pigskin. It can be seen from Figure 7 that the adhesive materials prepared in Examples 1-5 have similar nuclide removal efficiencies, indicating that the implementation schemes of the present invention have steady-state universality; while the nuclide removal performance of the polymer material prepared in Comparative Example 2 is much lower than that of the highly adhesive adhesive materials prepared in Examples 1-5 and Comparative Example 1, indicating that good adhesion performance design is one of the decisive factors for the nuclide removal effect on the substrate surface interface.

[0093] Figure 8 The nuclide removal efficiency of the highly adhesive adhesives prepared in Examples 1-7 on the surface of pigskin. It can be seen from Figure 8 that on the basis of Example 1, in Example 6, lignin fibers were used to modify plant polyphenols, so that plant polyphenols were grafted with lignin fibers containing phenolic hydroxyl groups, improving the chelating ability of plant polyphenols, and thus enhancing the nuclide removal efficiency; on the basis of Example 6, in Example 7, before grafting lignin fibers, they were pretreated to expose more phenolic hydroxyl groups, further enhancing the activity of lignin fibers, and thus improving the nuclide removal efficiency of plant polyphenols.

[0094] Although the implementation schemes of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation manners. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the examples shown and described here.
