Description

Technical Field

[0001] The present invention relates to the technical field of adhesives, and particularly to a preparation method of an antiviral beauty glue. Background Art

[0002] In recent years, public health problems caused by viral infections have become increasingly severe. Epidemic diseases such as seasonal influenza and hand, foot, and mouth disease pose significant risks in crowded scenarios such as schools, hospitals, and homes, having an adverse impact on public health, living order, and economic operation. Against this background, materials with antiviral functions have become an important research direction for preventing and controlling infections. In particular, "beauty glue", represented by sealants for indoor decoration, has attracted much attention due to its direct contact with the human body and the environment, and its safety and effectiveness are highly concerned.

[0003] In recent years, the influenza A (H3N2) virus has been relatively prevalent in winter. Influenza A (H3N2) is a subtype of the influenza A virus. The symptoms of influenza A caused by this virus are similar to those caused by other types of influenza A viruses, and are similar to those of ordinary influenza, including fever (fever caused by viral infection is generally persistent, but the temperature is higher in the afternoon than at other times), cough, sore throat, body aches, headache, chills, and fatigue. Some may also experience diarrhea and vomiting, and severe cases may be complicated by pneumonia and respiratory failure, and even death. Currently, there is relatively little research on beauty glue that resists the influenza A (H3N2) virus.

[0004] The current research direction of beauty glue mainly focuses on the optimization of properties such as mildew resistance, weather resistance, and mechanics. The prior art with the application number 202510245681.6 provides a preparation method of an ethyl lactate-removing silicone sealant, which improves the strength, transparency, and curing speed of the sealant through the preparation and mixing process of fine hydrophilic fillers and hydrophobic fillers. The prior art with the application number 202411613724.3 significantly improves the mildew resistance and comprehensive performance of beauty glue through innovative design of reactive mildew inhibitors and composite fillers. There are obvious shortcomings in the antiviral performance of the prior art, and the relevant research is relatively limited, making it difficult to meet the growing market demand for beauty glue products with reliable antiviral functions. In various public places such as beauty salons and hospitals, as well as in daily life, people's demand for beauty glue products that can effectively resist virus attacks is becoming increasingly urgent.

[0005] In summary, the prior art has the following technical problems: poor antiviral effect. Developing a beauty glue with good antiviral performance is of great significance for improving the level of public health protection and the practical value of materials. Summary of the Invention

[0052] Performance Test of Example 6 (1) Test the physical properties such as tensile strength, bonding strength, elastic recovery rate, and Shore hardness of the beauty glues prepared in Examples 1-5 and the comparative example. The specific test results are shown in Table 1.

[0053] Table 1 Test Results of Physical Properties of Beauty Glues in Examples 1-5 and the Comparative Example

[0054] It can be seen from the test results in Table 1 that the physical properties of Examples 1-5 are significantly improved compared with the comparative example. The tensile strength reaches 2.39 - 2.68 MPa. The high tensile strength enables the glue layer to withstand external pulling and avoid breakage, thus extending the service life. The bonding strength is 1.87 - 2.26 MPa. The relatively high bonding strength can ensure the firm bonding of the beauty glue to the substrate and reduce the problem of glue peeling caused by thermal expansion and contraction. The elastic recovery rate is 95 - 98%. The excellent elastic recovery ability can adapt to the minor deformation of the substrate, prevent the glue layer from cracking, and maintain the sealing integrity. The Shore hardness is 57 - 62 Shore A. The moderate Shore hardness can balance flexibility and support, adapt to the deformation of the substrate, reduce stress concentration, and at the same time avoid the collapse caused by the glue layer being too soft or the brittle cracking caused by the glue layer being too hard.

[0055] (2) Test the performance of the surface drying time of the beauty glues obtained in Examples 1-5 and the comparative example. The specific test results are shown in Table 2.

[0056] Table 2 Test Results of the Surface Drying Time Performance of Beauty Glues in Examples 1-5 and the Comparative Example

[0057] As can be seen from the test results in Table 2, the surface drying times of Examples 1-5 are significantly lower than those of the comparative examples, reaching 13.5-16.0 min. A short surface drying time means that a solid film can be quickly formed on the surface of the beauty glue, improving the construction efficiency, avoiding surface contamination, affecting the aesthetics and sealing performance, enabling the glue layer to quickly have preliminary water resistance and scrub resistance, and improving the reliability of initial use.

[0058] (3) The beauty glue obtained from Examples 1-5 and the comparative examples was tested for antiviral performance, and the specific test results are shown in Table 3.

[0059] Table 3 Test results of the antiviral performance of the beauty glue of Examples 1-5 and the comparative examples

[0060] As can be seen from the test results in Table 3, the antiviral performance of Examples 1-5 is significantly improved compared with that of the comparative examples, and the virus inactivation rate reaches 99.85-99.93%. The beauty glue containing the Ag-ZnO composite nanoparticles can inhibit the virus activity through the release of silver ions and the photocatalytic effect of ZnO, reducing the risk of cross-infection. The modified silica carrier can stably disperse the antibacterial components, avoiding agglomeration and failure, and ensuring the long-term antiviral effect.

[0061] In summary, from the test analysis of physical properties, antiviral performance, surface drying time and other properties, it can be seen that an antiviral beauty glue of the present invention has good physical properties, excellent antiviral performance and a short surface drying time, meeting the high standards of home decoration in terms of construction convenience, durability, and hygienic safety, and is especially suitable for modern family scenarios with requirements for environmental protection and antiviral properties.

[0062] The specific parameters of the raw materials used in the present invention are as follows: The viscosity of the quaternary ammonium salt modified siloxane is 100-500 mPa·s, and the molecular weight is 1000-3000 g / mol.

[0063] The particle size of the silica is 50-100 nm.

[0064] The particle size of the zirconium phosphate nanosheets is 0.5-2 μm.

[0065] Obviously, there are many specific implementation methods that can be changed under the concept of the present invention. Here, it should be stated that any changes made under the inventive concept of the present invention will fall within the protection scope of the present invention.
