Description

Technical Field

[0001] This application relates to the field of medical and health technology, and in particular to an easily identifiable disinfectant wipe, its preparation method, and its application. Background Technology

[0002] As human society develops, viruses are constantly evolving. Existing disinfection methods mainly involve spraying liquid disinfectants such as alcohol and 84 disinfectant, or ultraviolet disinfection and high-temperature disinfection. However, these methods have short-term effects. After the alcohol and 84 disinfectant evaporate, or after being removed from ultraviolet radiation and high temperatures, bacteria and viruses will continue to grow. Alternatively, antibacterial coatings can be applied to the surface of objects to form an antibacterial film, thus achieving a long-lasting antibacterial effect. However, the condition of the antibacterial film formed by this method is not easy to observe. If the film is damaged, it is difficult to detect the damage in time, thus allowing viruses and bacteria to continue to multiply.

[0019] The wet wipe base fabric is soaked in the easily identifiable disinfectant wipe stock solution. After the solution is saturated, the excess easily identifiable disinfectant wipe stock solution is removed to obtain the easily identifiable disinfectant wipe.

[0020] This application also provides the application of the above-mentioned easily identifiable disinfectant wipes or easily identifiable disinfectant wipes prepared by the above-mentioned preparation method in civilian and / or medical disinfection products; when applying, the surface of the object to be disinfected is cleaned and kept dry, and the easily identifiable disinfectant wipes are used to wipe the surface of the object to be disinfected evenly.

This helps people to promptly observe the adhesion of the antibacterial film on various object surfaces, thereby allowing for timely disinfection of damaged areas and preventing the spread of bacteria and viruses. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0023] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. In addition, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0024] As human society continues to develop, viruses are also constantly evolving. Current disinfection methods mainly involve spraying liquid disinfectants such as alcohol and 84 disinfectant, ultraviolet disinfection, and high-temperature disinfection. However, these types of disinfection methods have short-term effectiveness. After the alcohol and 84 disinfectant evaporate, or after being removed from ultraviolet radiation and high temperatures, bacteria and viruses will continue to grow. Alternatively, antibacterial coatings can be applied to the surface of objects to form an antibacterial film. However, the condition of this antibacterial film is not easy to observe. If the film is damaged, it is difficult to detect the damage in time, thus allowing viruses and bacteria to continue to multiply.

[0025] In view of this, this application proposes an easily identifiable disinfectant wipe. Simply wipe the surface of an object with the easily identifiable disinfectant wipe, and after the undiluted disinfectant wipe on the surface of the object dries, a long-lasting antibacterial film layer can be formed. By irradiating the antibacterial film layer on the surface of the object with ultraviolet light, the adhesion of the antibacterial film layer can be clearly identified.

[0026] The first aspect of this application provides an easily identifiable disinfectant wipe, comprising: a wipe base fabric and an easily identifiable disinfectant wipe concentrate incorporated therein.

[0027] The wet wipe base fabric can be wet-strength paper or non-woven fabric; for example, the wet wipe base fabric is viscose-polyester blended spunlace non-woven fabric, pure cotton spunlace non-woven fabric, or PP-wood pulp composite non-woven fabric, etc.; the shape, size and pattern of the wet wipe base fabric are not limited in this embodiment; for example, the wet wipe base fabric is a base fabric with embossed patterns, a base fabric with pearl jacquard patterns, or a plain weave base fabric, etc.

[0028] The easily identifiable disinfectant wipe stock solution, by weight, comprises: 60-80 parts of water-based resin, 4-10 parts of film-forming aid, 0.5-3 parts of special additives, 0.1-1 parts of amine neutralizer, 5-20 parts of deionized water, 0.1-10 parts of antibacterial agent, 0.01-0.5 parts of ultraviolet light display agent, and 0.1-0.5 parts of fragrance. Through the synergistic effect of specific components and proportions, the easily identifiable disinfectant wipe stock solution achieves effective and long-lasting disinfection and antibacterial effects. After drying, the disinfectant wipe stock solution forms a long-lasting antibacterial film on the surface of objects. The adhesion of the antibacterial film can be quickly identified by ultraviolet light irradiation, facilitating the observation of the disinfection and antibacterial status of objects.

[0029] In this embodiment, a long-lasting antibacterial solution is impregnated in the base fabric of the wipes, which can then be packaged in small bags for easy carrying. Compared to conventional liquid disinfectants, the easily identifiable disinfectant wipes do not contain flowing liquid, thus reducing the risk of leakage. Furthermore, when using them, simply wipe the surface of the object to be disinfected with the easily identifiable disinfectant wipes to achieve disinfection. Compared to the spraying method of conventional liquid disinfectants, the easily identifiable disinfectant wipes are simple to use and have no special requirements on the shape of the object being disinfected; they can be leather tables and chairs, desktops, or door handles, etc. After the easily identifiable disinfectant solution dries on the object's surface, a long-lasting antibacterial film is formed, achieving both disinfection and long-lasting antibacterial effect. Simultaneously, ultraviolet light irradiation can quickly identify the adhesion of the antibacterial film on the object's surface, helping people to promptly observe the adhesion of the antibacterial film on various object surfaces, thereby allowing for timely disinfection of any damaged areas and preventing the spread of bacteria and viruses.

[0030] Furthermore, the waterborne resin includes one or more of the following: waterborne alkyd resin, waterborne polyester resin, waterborne acrylic resin, and waterborne polyurethane resin.

[0031] Water-based resins serve as the film-forming carrier for disinfectant wipes. Their content can be 60, 65, 78, or 80 parts. Furthermore, the combined use of multiple water-based resins can achieve better film-forming effects, such as improving the adhesion of the antibacterial film. There is no limitation on the mixing ratio of multiple water-based resins. In actual production, different water-based resins can be mixed or selected according to different effect requirements or performance requirements, such as adhesion, solvent resistance, or aging resistance, to achieve multiple functions.

[0032] Furthermore, the film-forming aid includes one or more of the following: dodecyl alcohol ester, propylene glycol monomethyl ether, dipropylene glycol butyl ether, diethylene glycol butyl ether, dipropylene glycol methyl ether, propylene glycol methyl ether acetate, ethylene glycol butyl ether, and propylene glycol butyl ether.

[0033] Film-forming aids can promote the plastic and elastic flow of latex particles, thereby improving their aggregation properties. This allows easily identifiable disinfectant wipes to form films on a wide range of object surfaces. Furthermore, the film-forming aids will slowly evaporate after the film is formed, thus not affecting the antibacterial effect of the film.

[0034] Furthermore, the special additives include one or more of the following: wetting and dispersing agents, defoamers, thickeners, leveling agents, hand feel agents, and scratch-resistant agents.

[0035] Special additives can improve the production process of easily identifiable disinfectant wipes, increase the production efficiency of wipes, improve the storage stability of wipes, improve the application (wiping, smearing) conditions, prevent the unhealthy state of the wipe concentrate, and further improve the quality of wipes.

[0036] Furthermore, the amine neutralizing agent includes one or more of the following: N,N-dimethylethanolamine, triethanolamine, ammonia, diethylethanolamine, and 2-amino-2-methyl-propanol.

[0037] Amine neutralizers can adjust the pH value of wet wipe concentrate formulations, making the wet wipe concentrate formulation system more stable and promoting the system to exert its maximum efficacy under suitable pH conditions.

[0038] Furthermore, the antibacterial agent includes one or more of the following: nano-metal antibacterial agents, organic antibacterial agents, and bio-based antibacterial agents.

[0039] Nano-metal antibacterial agents possess a large specific surface area, can dissociate into metal ions, and exert inhibitory effects on Escherichia coli, Staphylococcus aureus, and other bacteria, exhibiting excellent antibacterial properties. Furthermore, nano-metal antibacterial agents have low biotoxicity, thereby improving the safety of easily identifiable disinfectant wipes. Examples of nano-metal antibacterial agents include nano-silver wire antibacterial agents, nano-zinc oxide, and nano-copper oxide. Organic antibacterial agents can bind to anions on the surface of pathogenic microorganism cell membranes or react with sulfhydryl groups, thereby disrupting protein structure or affecting biofilm synthesis, thus inhibiting the reproduction of pathogenic microorganisms and achieving antibacterial effects. Examples of organic antibacterial agents include chlorhexidine acetate, polyhexamethylene biguanide hydrochloride, benzalkonium chloride (bromide), diseconazole dimethyl ammonium chloride, 1,2-benzisothiazolin-3-one, 5-chloro-2-methyl-4-isothiazolin-3-one, and 2-octyl-4-isothiazolin-3-one. Bio-based antibacterial agents are extracted from biomass resources and are characterized by safety, environmental friendliness, and high efficiency.

[0040] In this embodiment, the combined action of one or more antibacterial agents among nano-metal antibacterial agents, organic antibacterial agents, and bio-based antibacterial agents enables easily identifiable disinfectant wipes to have broad-spectrum bactericidal and antibacterial effects, with an antibacterial rate of more than 99.99% against Escherichia coli, Staphylococcus aureus, H1N1, and the novel coronavirus. Furthermore, the antibacterial film formed has a long-lasting antibacterial and antiviral effect, low toxicity and side effects, and is environmentally friendly.

[0041] Furthermore, the ultraviolet light display agent includes one or more of the following: inorganic pigments, organic pigments, and fluorescent agents.

[0042] Ultraviolet (UV) light display agents enable antibacterial films to be easily identified under UV light irradiation, helping people to observe the adhesion of antibacterial films on the surfaces of various objects in a timely manner, thereby enabling timely disinfection of damaged areas and preventing the spread of bacteria and viruses. The UV light display agent used in this application is non-toxic and does not affect the appearance of the attached object or the performance of the carrier under normal light.

[0043] Furthermore, the fragrance includes: natural fragrance or chemically synthesized fragrance.

[0044] Fragrances can give products a pleasant scent and can mask the original smell of some ingredients in the wet wipe liquid, making the wet wipes smell better and improving the user experience.

[0045] In this embodiment, the easily identifiable disinfectant wipes combine a long-lasting antibacterial solution with a wipe base fabric, providing a disinfectant wipe with excellent antibacterial properties. Compared to conventional liquid disinfectants, it is convenient to carry and easy to use. Simply wipe the easily identifiable disinfectant wipes onto the surface of the object to be disinfected to achieve disinfection. Furthermore, the components in the easily identifiable disinfectant wipe solution effectively ensure both the antibacterial and antiviral effects of the wipe solution and its dispersion stability and film-forming effect. This facilitates the application of the easily identifiable disinfectant wipes to different object surfaces, forming an antibacterial film layer. It is flexible, convenient, and widely adaptable, possessing extremely high application value.

[0046] The easily identifiable disinfectant wipes of this application embodiment can be prepared by the methods described in the following embodiments.

[0047] The second aspect of this application provides a method for preparing easily identifiable disinfectant wipes, comprising the following steps:

[0048] Step S10: Mix the aqueous resin, special additives and deionized water, and stir at 400-800 r / min for 10-30 min to obtain solution A;

[0049] Step S20: Add the film-forming aid to solution A and stir at 400-800 r / min for 20-30 min to obtain solution B;

[0050] Step S30: Add the amine neutralizing agent to the solution B, control the pH at 7.0-9.0, and stir at 400-800 r / min for 10-20 min to obtain solution C;

[0051] Step S40: Add the ultraviolet light display agent, fragrance and antibacterial agent to the solution C in sequence, stir at 400-800 r / min for 20-30 min and then filter to obtain the easily identifiable disinfectant wipe stock solution;

[0052] Step S50: Soak the wet wipe base fabric in the easily identifiable disinfectant wipe stock solution. After the absorbent is saturated, remove the excess easily identifiable disinfectant wipe stock solution to obtain the easily identifiable disinfectant wipe.

[0053] In this embodiment, the easily identifiable disinfectant wipe stock solution is combined with a wipe base fabric to obtain easily identifiable disinfectant wipes. The preparation method is simple and mild, suitable for large-scale industrial production and application. The prepared easily identifiable disinfectant wipes have good antibacterial and antiviral effects, with antibacterial rates greater than 99.99% against Escherichia coli, Staphylococcus aureus, H1N1, and the novel coronavirus. Furthermore, the easily identifiable disinfectant wipes are simple to use; simply wiping the surface of an object with the wipes disinfects it, forming a long-lasting antibacterial film. By irradiating the surface with ultraviolet light, it is possible to quickly determine whether an area is covered with the antibacterial film, allowing for timely disinfection of any damaged areas and further preventing the spread of bacteria and viruses.

[0054] The third aspect of this application provides an application of easily identifiable disinfectant wipes, including: application in civilian and / or medical disinfectant products.

[0055] When applying the disinfectant, clean the surface of the object to be disinfected and keep it dry. Wipe the surface evenly with the easily identifiable disinfectant wipes. After the residual disinfectant solution on the surface dries, an antibacterial film is formed. The object to be disinfected can be leather tables and chairs, tabletops, door handles, etc., and this embodiment does not limit this.

[0056] In this embodiment, easily identifiable disinfectant wipes have a wide range of applications, are flexible and convenient to use, and are highly adaptable, thus possessing extremely high application value.

[0090] Furthermore, to verify the progressiveness of the embodiments of this application, the following performance tests were performed on each embodiment and comparative example:

[0091] Antibacterial test: The method in GB / T 21866-2008 "Determination of antibacterial properties and antibacterial effects of antibacterial coatings (films)" was adopted; the antibacterial test results are shown in Table 1 below:

[0092] Table 1

[0093]

[0094] As shown in Table 1 above, the antibacterial film produced by the easily identifiable disinfectant wipes prepared in Examples 1-8 of this application exhibits superior antibacterial effects against Escherichia coli and Staphylococcus aureus compared to the conventional disinfectant products in Comparative Examples 1-4. Specifically, the antibacterial rate of the film layers in Examples 2-4 and 6-8 all reached over 99%. Comparing Examples 1-4, it can be observed that the antibacterial rate of the antibacterial film layer increases with the increase of the content of the silver nanowire antibacterial agent, reaching its optimal antibacterial effect at a content of 5 parts. Subsequently, the antibacterial effect remains almost unchanged with further increases in the content of the silver nanowire antibacterial agent. Comparing Examples 5-8, it can be observed that the antibacterial rate of the antibacterial film layer increases with the increase of the chlorhexidine acetate content, reaching its optimal antibacterial effect at a content of 1 part. Subsequently, the antibacterial effect remains almost unchanged with further increases in the content of chlorhexidine acetate. Comparing Examples 2 and 6, it can be found that both antibacterial membranes have extremely high antibacterial effects, with an inhibition rate of 99.99%. In Example 6, chlorhexidine acetate was added, and compared with Example 2, the content of nano-silver wire antibacterial agent added in Example 6 was less, but the antibacterial effect was almost the same. This indicates that the higher content of nano-silver wire antibacterial agent in the membrane, or the presence of both nano-silver wire antibacterial agent and chlorhexidine acetate, can significantly improve the antibacterial effect of the membrane through the synergistic effect of the two.

[0095] Antiviral test: The method in ISO 21702:2019 was used; the antiviral test results are shown in Table 2 below:

[0096] Table 2

[0097]

[0098] As shown in Table 2 above, the antibacterial film produced by the easily identifiable disinfectant wipes prepared in Examples 1-8 of this application exhibits superior antiviral effects against both H1N1 and the novel coronavirus compared to conventional disinfectant products in Comparative Examples 1-4. Specifically, the antiviral activity rate of the film layers in Examples 2-4 and Examples 6-8 all reached over 99%. Comparing Examples 1-4, it can be observed that the antiviral activity rate of the antibacterial film layer increases with the increase of the content of the silver nanowire antibacterial agent, reaching its optimal antiviral effect at a content of 5 parts. Subsequently, the antiviral effect remains almost unchanged with further increases in the content of the silver nanowire antibacterial agent. Comparing Examples 5-8, it can be observed that the antiviral activity rate of the antibacterial film layer increases with the increase of the chlorhexidine acetate content, reaching its optimal antiviral effect at a content of 1 part. Subsequently, the antiviral effect remains almost unchanged with further increases in the chlorhexidine acetate content. Comparing Examples 2 and 6, it can be found that both antibacterial membranes have extremely high antiviral effects, with an antiviral activity rate of 99.99%. In Example 6, chlorhexidine acetate was added, and compared with Example 2, the content of nano-silver wire antibacterial agent added in Example 6 was less, but the antiviral effect was almost the same. This indicates that the higher content of nano-silver wire antibacterial agent in the membrane, or the presence of both nano-silver wire antibacterial agent and chlorhexidine acetate as antiviral components, can significantly improve the antiviral effect of the membrane through their synergistic effect.

[0099] Rapid antibacterial performance test: Based on the method in GB / T 21866-2008 "Determination of antibacterial properties and antibacterial effects of antibacterial coatings (films)", the test time was changed to 15 min, 30 min, 1 h, 6 h and 24 h; the results of the rapid antibacterial performance test are shown in Table 3 below:

[0100] Table 3

[0101]

[0102] As shown in Table 3 above, the antibacterial film produced by the easily identifiable disinfectant wipes prepared in Examples 1-8 of this application exhibits superior antibacterial effects against Escherichia coli and Staphylococcus aureus compared to the conventional disinfectant products in Comparative Examples 1-4, and the antibacterial effect is rapid. Specifically, in Examples 2-4 and 6-8, the antibacterial film reached its optimal antibacterial effect within 30 minutes. Comparing Examples 1-4, it can be observed that with the addition of nano-silver wire antibacterial agent, the time for the antibacterial film to reach its optimal antibacterial effect is shortened, reaching a minimum of 30 minutes when the nano-silver wire antibacterial agent content is 5 parts. Subsequently, with the increase of the nano-silver wire antibacterial agent content, the time to reach the optimal antibacterial effect remains almost unchanged. Comparing Examples 5-8, it can be observed that with the addition of chlorhexidine acetate, the time for the antibacterial film to reach its optimal antibacterial effect is shortened, reaching a minimum of 30 minutes when the chlorhexidine acetate content is 1 part. Subsequently, with the increase of the chlorhexidine acetate content, the time to reach the optimal antibacterial effect remains almost unchanged. Comparing Examples 2 and 6, it can be found that both antibacterial films have extremely high antibacterial effects, with an inhibition rate of 99.99%, and both reach their optimal antibacterial effect within 30 minutes. In Example 6, chlorhexidine acetate was added, and compared to Example 2, Example 6 added less nano-silver wire antibacterial agent, but the antibacterial effect and onset time were almost the same. This indicates that the higher content of nano-silver wire antibacterial agent in the film, or the simultaneous presence of both nano-silver wire antibacterial agent and chlorhexidine acetate, can significantly improve the antibacterial effect and onset time of the film through their synergistic effect.

[0103] Rapid antiviral efficacy test: Based on the method in ISO 21702:2019, the test time was changed to 15 min, 30 min, 1 h, 6 h, and 24 h; the results of the rapid antiviral efficacy test are shown in Table 4 below:

[0104] Table 4

[0105]

[0106] As shown in Table 4 above, the antibacterial film produced by the easily identifiable disinfectant wipes prepared in Examples 1-8 of this application exhibits superior antiviral effects against both H1N1 and the novel coronavirus compared to conventional disinfectant products in Comparative Examples 1-4, and the antiviral effect is rapidly observed. Specifically, in Examples 2-4 and 6-8, the antibacterial film reached its optimal antiviral effect within 30 minutes. Comparing Examples 1-4 reveals that as the content of the nano-silver wire antibacterial agent increases, the time required for the antibacterial film to reach its optimal antiviral effect shortens, reaching a minimum of 30 minutes when the nano-silver wire antibacterial agent content is 5 parts. Subsequently, the time to reach the optimal antiviral effect remains almost unchanged with further increases in the nano-silver wire antibacterial agent content. Comparing Examples 5-8 reveals that as the chlorhexidine acetate content increases, the time required for the antibacterial film to reach its optimal antiviral effect shortens, reaching a minimum of 30 minutes when the chlorhexidine acetate content is 1 part. Subsequently, the time to reach the optimal antiviral effect remains almost unchanged with further increases in the chlorhexidine acetate content. Comparing Examples 2 and 6, it can be found that both antibacterial membranes have extremely high antiviral effects, with antiviral activity rates reaching 99.99%, and both achieving optimal antiviral effects within 30 minutes. Example 6 added chlorhexidine acetate, and compared to Example 2, Example 6 added less nano-silver wire antibacterial agent, yet the antiviral effect and onset time were almost identical. This indicates that a higher content of nano-silver wire antibacterial agent in the membrane, or the presence of both nano-silver wire antibacterial agent and chlorhexidine acetate, can significantly improve the antiviral effect and onset time of the membrane through their synergistic effect.
