Description
Cleaning and coating composition capable of cleaning and coating
[0001] The present invention relates to a cleaning coating composition capable of cleaning and coating.
[0002] More specifically, the present invention relates to a cleaning coating composition capable of cleaning glass and forming a waterproof and antifouling coating at the same time, and can be applied to various surfaces such as building exterior glass, large indoor glass, automobile interior and exterior windows, bathroom glass, and mirrors.
[0003] While existing glass cleaners can be effective in removing contaminants, they lack a coating effect, limiting their long-term ability to prevent contamination and protect surfaces. In other words, existing glass cleaners lack a coating effect after cleaning, limiting their ability to prevent recurrence of contamination and protect surfaces.
[0004] In particular, for glass exposed to high temperature and high humidity environments, such as building exterior glass or bathroom mirrors, continuous cleaning management is required as well as prevention of contamination by water stains or moisture.
[0005] Likewise, in the case of automobiles, re-contamination is prevented by coating after washing, but the existing method requires the use of separate detergents and coating agents, which is cumbersome.
[0006] There are various reasons why cleaning and coating were performed separately in the past, but one of the reasons is that the surfactant added to secure cleaning power leaves residual surfactant even after cleaning, which results in poor coating performance.
[0007] Patent Document 1 discloses a vehicle coating agent capable of simultaneously cleaning and water-repelling a vehicle surface. Patent Document 1 includes a siloxane and a surfactant, but addresses degradation issues by essentially including a cationic water-soluble polymer compound and performing multiple coating processes.
[0008] Patent Document 2 discloses a composition having gloss and water-repellent effects. Patent Document 2 contains siloxane and a surfactant, but aims to secure a composition capable of immediate coating after washing without the need for separate moisture removal, as it has surface water droplet repellency.
[0009] There is a need to develop a cleaning coating composition that has both excellent cleaning power and excellent coating properties, and a technology for manufacturing the same.
[0010] The purpose of the present invention is to provide a cleaning coating composition capable of cleaning and coating and a method for producing the same.

[0039] Unless otherwise specified, the notation 'A to B' or 'A to B' for numerical values A and B means 'A or more and B or less'. In such notation, if a unit is attached only to numerical value B, the unit shall also be applied to numerical value A.
[0040] Also, unless otherwise stated, 1 ppm is 0.0001 wt%.
[0041]
[0042] The present disclosure relates to a cleaning coating composition. According to one embodiment disclosed herein, the cleaning coating composition comprises a nonionic surfactant and an amino-modified silicone.
[0043] When excessive amounts of surfactant are included to ensure cleaning power, it is difficult to secure coating properties. However, according to one embodiment disclosed herein, by including a nonionic surfactant and appropriately controlling the content range of amino-modified silicone, excellent cleaning power and excellent coating properties can be secured simultaneously.
[0044] The cleaning coating composition may contain a nonionic surfactant and an amino-modified silicone in an amount of 1% or more and 20% or less. The lower limit of the nonionic surfactant and the amino-modified silicone in the cleaning coating composition may be about 1%, 1.5%, 2%, or 2.5%, and the upper limit may be about 20%, 15%, or 10%. The content of the nonionic surfactant and the amino-modified silicone may be included within a range of more than or exceeding the aforementioned lower limit and less than or equal to the aforementioned upper limit.
[0045] The cleaning coating composition may contain a nonionic surfactant and an amino-modified silicone within a certain ratio range, for example, a weight % ratio in the range of 1:(0.1 to 5). More specifically, the weight % ratio of the nonionic surfactant and the amino-modified silicone may be about 1:0.1, 1:0.2, or 1:0.5. If the weight ratio of the amino-modified silicone to the nonionic surfactant is less than the above-mentioned range or exceeds the above-mentioned upper limit, even if cleaning power can be secured, it is difficult to secure coating properties, and thus waterproofing and / or stain resistance may be reduced, and stains may occur on the surface of the glass or the like after applying the composition to the glass or the like and / or removing the composition with a water-soluble substance. Therefore, the cleaning coating composition according to one embodiment disclosed in the present specification can provide a cleaning coating composition capable of securing cleaning power and coatability by controlling the weight % ratio of the nonionic surfactant and the amino-modified silicone (weight % ratio of the amino-modified silicone to the nonionic surfactant) within the above-described range.
[0046] Nonionic surfactants can effectively cleanse contaminants by emulsifying them. Nonionic surfactants can remove both organic and / or inorganic contaminants, making them suitable for a variety of environments. Furthermore, nonionic surfactants can facilitate the mixing of amino-modified silicone, which is hydrophobic, and water within the composition.
[0047] More specifically, the cleaning coating composition may include a nonionic surfactant within a certain range. The lower limit of the nonionic surfactant in the cleaning coating composition may be about 1%, 2%, 3%, 4%, or 5%, and the upper limit may be about 15%, 10%, or 5%. The content of the nonionic surfactant may be included within a range equal to or greater than the aforementioned lower limit, or equal to or less than the aforementioned upper limit.
[0048] If the content of the nonionic surfactant is less than the lower limit described above, it may be difficult to ensure the homogeneity of the cleaning coating composition because it is difficult to mix the hydrophobic component and water in the composition, and it may be difficult to secure cleaning power, or the coating components may not be evenly distributed, resulting in uneven coating. If the content of the nonionic surfactant exceeds the upper limit described above, the residual amount of the surfactant may be large even after applying the composition to glass or the like and / or removing the composition with a water-soluble substance, which may cause stains or stickiness on the surface of glass or the like, and may reduce waterproofing and / or stain-repelling properties by interacting with the coating components in the composition. Therefore, the cleaning coating composition according to one embodiment disclosed herein may include a nonionic surfactant within the above-described range.
[0049] The nonionic surfactant may be one or more of polyoxyethylene alkyl ethers, sorbitan esters, polysorbates, polyoxyethylene-polyoxypropylene, alkyl polyglucosides, fatty alcohol ethoxylates, and amine oxides.
[0050] Amino-modified silicone can form a coating layer on glass or mirror surfaces, providing both water-repellent and stain-resistant properties. By appropriately incorporating amino-modified silicone with the aforementioned nonionic surfactant, the resulting product can maintain excellent coating properties while minimizing residual surfactant, thereby preventing re-contamination.
[0051] The amino-modified silicone may be represented by the following chemical formula 1.
[0052] [Chemical Formula 1]
[0053]
[0054] In chemical formula 1, R may be hydrogen, an alkyl group having 1 to 3 carbon atoms, a hydroxy group, or an alkoxy group. In addition, in chemical formula 1, x may be in the range of 5 to 100.
[0055] A is represented by the following chemical formula 2, and y can be in the range of 1 to 10.
[0056] [Chemical Formula 2]
[0057]
[0058] In chemical formula 2, R may be hydrogen, an alkyl group having 1 to 3 carbon atoms, a hydroxyl group, or an alkoxy group. In addition, in chemical formula 2, a may be in the range of 2 to 10, b may be in the range of 1 to 10, c may be in the range of 1 to 10, and d may be in the range of 0 to 5.
[0059] B is represented by the following chemical formula 3, and z can be in the range of 1 to 10.
[0060] [Chemical Formula 3]
[0061]
[0062] In chemical formula 3, R can be hydrogen, an alkyl group having 1 to 3 carbon atoms, a hydroxy group, or an alkoxy group. e can be in the range of 2 to 10.
[0063] The cleaning coating composition may appropriately contain amino-modified silicone to provide excellent coating properties. More specifically, the lower limit of the nonionic surfactant in the cleaning coating composition may be approximately 0.1%, 0.2%, 0.3%, 0.4%, or 0.5%, and the upper limit may be approximately 10%, 8%, 6%, 4%, or 2%. The content of the amino-modified silicone may be within a range equal to or greater than the aforementioned lower limit, or equal to or less than the aforementioned upper limit.
[0064] If the content of amino-modified silicone is less than the lower limit described above, it may be difficult to secure coatability, and thus, waterproofness and / or stain resistance may decrease, and surface gloss and transparency may deteriorate. If the content of amino-modified silicone exceeds the upper limit described above, stains or stickiness may occur on the surface of glass or the like even after applying the composition to glass or the like and / or removing the composition with a water-soluble substance, and mixing with other components may not be easy, which may reduce the stability of the cleaning coating composition. Therefore, the cleaning coating composition according to one embodiment disclosed in the present specification may include amino-modified silicone within the above-described range.
[0065] A cleaning coating composition according to one embodiment disclosed herein comprises alcohol. By including alcohol in the cleaning coating composition, the solubility of contaminants can be ensured, thereby ensuring excellent cleaning power.
[0066] The alcohol may be one or more of ethanol, methanol, butanol, and isopropyl alcohol. More preferably, the alcohol included in the cleaning coating composition according to one embodiment disclosed herein may be isopropyl alcohol.
[0067] The cleaning coating composition may contain alcohol within a certain range. The lower limit of the alcohol content in the cleaning coating composition may be approximately 10%, 15%, or 20%, and the upper limit may be approximately 30%, 25%, or 20%. The alcohol content may be within a range that is equal to or greater than the aforementioned lower limit, or equal to or less than the aforementioned upper limit.
[0068] If the alcohol content falls below the lower limit described above, it may be difficult to secure cleaning power, or the mixing ability of the cleaning coating composition may decrease, which may lower the stability of the composition. In addition, if the alcohol content falls below the lower limit described above, the cleaning coating composition may take a long time to dry, which may cause stains to form on the surface. If the alcohol content exceeds the upper limit described above, the cleaning coating composition may evaporate quickly before securing cleaning power or coating properties, which may cause surface corrosion or discoloration of the object to be used. Therefore, the cleaning coating composition according to one embodiment disclosed herein may contain alcohol within the above-described range.
[0069] A cleaning coating composition according to one embodiment disclosed herein comprises, in addition to the nonionic surfactant, amino-modified silicone and alcohol described above, water and inevitable impurities.
[0070] The cleaning coating composition can have applicability suitable for various environments by including water as a residue.
[0071] A cleaning coating composition according to one embodiment disclosed in this specification comprises water in addition to the above-described nonionic surfactant, amino-modified silicone, and alcohol, and by appropriately controlling the contents thereof, it is possible to simultaneously secure excellent cleaning power and excellent coating properties.
[0072] The cleaning coating composition according to one embodiment disclosed herein may further comprise an additive. If the additive is included, it may be included in place of the water described above. If the additive is included, the cleaning coating composition may comprise the additive in an amount ranging from 0.05% to 5%.
[0073] The additive may be any one of a stabilizer, a viscosity modifier, an antibacterial agent, a fragrance, an antifouling agent, or nanoparticles. For example, when nanoparticles are included as an additive, the waterproofing, antifouling, or transparent coating properties of the cleaning coating composition can be further secured. In addition, the nanoparticles may be included in a state in which a composition capable of surface self-cleaning properties is applied. The additive is not essential in the cleaning coating composition according to one embodiment disclosed herein, and if it is an additive related to a physical property that a person of ordinary skill in the art wishes to further secure for the cleaning coating composition according to one embodiment disclosed herein, it may be optionally included.
[0074]
[0075] In addition, the present specification relates to a manufacturing method for manufacturing a cleaning coating composition.
[0076] A method for preparing a cleaning coating composition according to one embodiment disclosed herein includes a step of preparing a cleaning coating pre-component by mixing a nonionic surfactant and an amino-modified silicone, and a step of preparing a cleaning coating composition by mixing alcohol and water with the cleaning coating pre-component.
[0077] The step of preparing a cleaning coating component by mixing a nonionic surfactant and an amino-modified silicone may be a step of mixing the nonionic surfactant and the amino-modified silicone in a range of 1:(0.1 to 5).
[0078] Specific descriptions of the nonionic surfactant and amino-modified silicone are as described in the cleaning coating composition according to one embodiment disclosed in the present specification described above. For example, the weight percent ratio of the nonionic surfactant and amino-modified silicone, or the content of each of the nonionic surfactant and amino-modified silicone, are as described above.
[0079] The step of preparing a cleaning coating composition by mixing alcohol and water may be a step of preparing a cleaning coating composition by mixing 1% or more and 20% or less of the cleaning coating pre-ingredients, 10% or more and 30% or less of alcohol, and the remainder of water in the cleaning coating composition.
[0080] The specific description of the cleaning coating pre-components, alcohol and water, is as described in the cleaning coating composition according to one embodiment disclosed in the present specification described above. For example, the description of the alcohol content is as described above.
[0081] The method for manufacturing a cleaning coating composition according to one embodiment disclosed herein may further include a step of including any one of a stabilizer, a viscosity modifier, an antibacterial agent, a fragrance, an antifouling agent, or nanoparticles in a range of 0.05% to 5%. The stabilizer, viscosity modifier, antibacterial agent, fragrance, antifouling agent, or nanoparticles corresponds to an additive in the cleaning coating composition described above, and the description thereof is as described above.
[0082] The method for preparing a cleaning coating composition according to one embodiment disclosed herein requires mixing a nonionic surfactant and an amino-modified silicone followed by mixing alcohol and / or water. This is a sequential process, and if alcohol and / or water are mixed before mixing the nonionic surfactant and the amino-modified silicone, it may be difficult to secure the effects of the present invention.
[0083] For example, if a nonionic surfactant is mixed with water before mixing the nonionic surfactant and amino-modified silicone, the surfactant may dissolve in water, making it difficult to secure the cleaning power of the cleaning coating composition, and the mixing power with the amino-modified silicone included later may be inferior. In this case, as described in the cleaning coating composition, there is a concern that the stability of the composition may be reduced due to a decrease in cleaning power and / or a decrease in mixing power.
[0084] Additionally, for example, when alcohol is mixed with a nonionic surfactant or amino-modified silicone prior to mixing the nonionic surfactant and amino-modified silicone, the rapid evaporation of the alcohol may result in a long drying time after applying the cleaning coating composition to glass or the like. In this case, as described above with respect to the cleaning coating composition, there is a risk of staining on the surface of glass or the like.
[0085] Therefore, the method for manufacturing a cleaning coating composition according to one embodiment disclosed in the present specification can provide a cleaning coating composition that can secure excellent cleaning power and excellent coating properties simultaneously by mixing a nonionic surfactant and amino-modified silicone in an appropriate weight ratio and then mixing water and alcohol in appropriate amounts.

[0103] (Method for measuring physical properties of cleaning coating composition)
[0104] 1. Cleaning power evaluation - visual distortion test
[0105] In each of the examples and comparative examples, the cleaning coating composition was applied to standard glass (width and length: 30 cm each, thickness: 3 mm) as specified in KS L 2012, left for about 10 minutes, and rinsed with running water for 10 seconds. Thereafter, the glass was evaluated by irradiating it with light having 70 lm / W at an angle of about 30° based on the direction perpendicular to the plane of the specimen.
[0106] PASS: If no surface streaks or stains are visible to the naked eye
[0107] FAIL: If surface streaks or stains are visible to the naked eye.
[0108]
[0109] 2. Coating Evaluation - Durability
[0110] The cleaning coating compositions manufactured in each of the examples and comparative examples were applied to a mirror with a width and length of 30 cm and a thickness of 3 mm, made of standard glass as specified in KS L 2012, left for about 10 hours, and then rinsed with running water for 10 seconds. Thereafter, soap foam with a pH of 10 was applied to the specimen, left for about 1 hour, and then durability was evaluated.
[0111] PASS: If no surface discoloration or peeling is visible to the naked eye
[0112] FAIL: If surface discoloration or peeling is visible to the naked eye.
[0113]
[0114] (Evaluation results of cleaning coating composition)
[0115] The results of evaluating the cleaning power and coating properties of the cleaning coating compositions of the above-mentioned manufactured examples and comparative examples are summarized in Table 2 below.

[0117] Referring to Tables 1 and 2 above, Examples 1 to 5 all satisfy the content range of the cleaning coating composition according to one embodiment disclosed in the present specification. Accordingly, when evaluating cleaning power, no visual distortion, i.e., surface stripes or stains, was observed, confirming that the residual amount of surfactant was small and that excellent cleaning power was secured. In addition, at the same time, when evaluating durability, no surface discoloration or peeling was observed with the naked eye, confirming that the coating layer was uniformly formed and that waterproofing and stain resistance were secured. Comparative Example 1 is a comparative example in which the content ratio of nonionic surfactant and amino-modified silicone and the content of amino-modified silicone did not fall within the scope of the present invention. Comparative Example 1 had insufficient waterproofing and / or stain resistance because the content of amino-modified silicone was very low, making it difficult to form a coating layer. In other words, Comparative Example 1 secured cleaning power but failed to secure coating properties.
[0118] Comparative Example 2 is a comparative example in which the content of amino-modified silicone exceeds the range disclosed in the present specification. In Comparative Example 2, the composition was unevenly applied with a large amount of amino-modified silicone, resulting in insufficient waterproofing and / or stain-repelling properties, and thus, while cleaning power was secured, coating properties were not secured. In other words, Comparative Example 2 secured cleaning power but failed to secure coating properties.
[0119] Comparative Example 3 is a comparative example in which the content of nonionic surfactant exceeds the range disclosed herein. In Comparative Example 3, the excessive surfactant inhibited coating formation, and the large amount of residual surfactant resulted in surface staining. In other words, Comparative Example 3 failed to secure cleaning power and coatability.
[0120] Comparative Example 4 is a comparative example in which the alcohol content falls below the range disclosed herein. In Comparative Example 4, the stability of the composition was reduced due to the lack of alcohol, and the surfactant was not properly rinsed away, resulting in surface stains. In other words, Comparative Example 4 failed to secure cleaning power and coating properties.
[0121] Comparative Example 5 is a comparative example in which the alcohol content exceeds the range disclosed herein. In Comparative Example 5, the large amount of alcohol in the composition rapidly evaporated, preventing the proper formation of a coating layer. In other words, Comparative Example 5 secured cleaning power but failed to secure coating properties.
[0122] Comparative Example 6 is a comparative example in which the content ratio of nonionic surfactant and amino-modified silicone and the content of amino-modified silicone exceed the scope of the present invention. In Comparative Example 6, the cleaning coating composition clumped and was applied unevenly due to excessive amino-modified silicone, resulting in inadequate waterproofing and / or stain-repelling properties. In other words, Comparative Example 6 secured cleaning power but failed to secure coating properties.
[0123] Comparative Example 7 is a comparative example in which alcohol was mixed before mixing the nonionic surfactant and amino-modified silicone. It was expected that Comparative Example 7 would take a long time to dry due to the rapid evaporation of alcohol. Even though Comparative Example 7 had the same content ratio as Example 5, stains were formed on the glass surface. In other words, Comparative Example 7 secured cleaning power but failed to secure coating properties.
[0124] Through the examples disclosed in this specification, it can be confirmed that even if cleaning power is secured with a surfactant, it is difficult to solve problems caused by a decrease in coating properties due to residual surfactant or a decrease in the coating properties themselves.
[0125] The significance of the present invention lies in the fact that a cleaning coating composition capable of simultaneously securing cleaning power and coating properties has been secured by appropriately controlling the content of a nonionic surfactant and amino-modified silicone and appropriately controlling the content of alcohol.
[0126]
[0127] As described above, preferred embodiments of the present invention have been described, and it is obvious to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope thereof, in addition to the embodiments described above.
[0128] Therefore, the above-described embodiments should be considered as illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description but may be modified within the scope of the appended claims and their equivalents.
