Description

Technical Field

[0001] The present invention relates to a maintenance and cleaning preparation, which is applied to the super-hydrophilic coatings on the kitchen walls, tiles, and household appliances. The present invention also discloses a preparation method and application of this maintenance and cleaning preparation. Background Art

[0002] In contemporary life, the cleaning of the kitchen environment and the maintenance of indoor and outdoor decorative coatings have become an important part of daily life. Oil fumes, steam, etc. in the kitchen will form oil stains on the walls, tiles, and household appliances, and these places are usually coated with a layer of super-hydrophilic coating, so the cleaning and maintenance problems are particularly important.

[0003] Currently, although there are cleaning and maintenance agents for oil fumes and super-hydrophilic coatings on the market, their respective effects are single, and there may be problems such as environmental protection and safety. For example, the patent US8835502B1 "Degreasing compositions and methods of making and using the same" describes a cleaning agent with strong degreasing ability. However, it is mainly composed of alkaline substances, surfactants, solvents, etc. Although it can effectively remove kitchen oil fumes, it may damage the super-hydrophilic coating and affect its service life.

[0004] The patent US8052914B2 "Water-based coating compositions" proposes a method for maintaining coatings. The coating has good durability and protection after drying. However, this method mainly targets the coating itself, and its ability to clean kitchen stains caused by oil fumes, steam, etc. is limited.

[0005] In China, there are also many patents that attempt to solve this problem. For example, CN102652885B "An environment-friendly water-based degreasing agent and its preparation method" provides an environment-friendly water-based degreasing agent mainly composed of ester compounds, alcohol compounds, and water. Although it can remove oil fume stains to a certain extent, its maintenance effect on coatings is not significant.

[0006] The patent CN101187295B "A coating maintenance agent and its preparation method and application" describes a coating maintenance agent that can effectively protect and maintain the surface performance of coatings, but its ability to clean oil fumes is relatively weak.

[0007] The patent CN101391670B "An environment-friendly cleaning agent and its preparation method and application" proposes an environment-friendly cleaning agent mainly composed of alkali metal salts, acidic oxidants, and surfactants. Although it has certain cleaning and degreasing abilities, its maintenance ability for coatings is insufficient, which may affect the performance and service life of coatings.

[0008] JP2004237406A "Detergent for kitchen equipment" describes a kitchen equipment cleaner mainly composed of an alkaline substance, an organic acid, and a surfactant. This cleaner can effectively remove grease stains on kitchen equipment, but its maintenance effect on super-hydrophilic coatings is not obvious.

[0009] Another patent, JP2015022794A "Water-repellent cleaning agent", covers a hydrophilic cleaning agent that can improve the stain resistance and hydrophilicity of coatings, but its effect on cleaning lampblack is relatively weak.

[0010] In summary, although existing cleaners and maintenance agents have their respective advantages, most of them can only solve one of the above problems and may contain chemical components harmful to the human body or the environment. At the same time, many traditional cleaning agents and maintenance agents may produce irritating odors during use, which may cause discomfort to the respiratory system of users. Prolonged use of these products may have an impact on the health of users. Therefore, there is an urgent need to develop a new type of cleaning and maintenance agent that can effectively clean kitchen lampblack, maintain super-hydrophilic coatings, have no irritating odor, and be harmless to the environment. Summary of the Invention

[0012] The second technical problem to be solved by the present invention is to provide another environmentally friendly clean and maintenance agent suitable for super-hydrophilic coatings in view of the above technical status.

[0013] The third technical problem to be solved by the present invention is to provide a preparation method of an environmentally friendly clean and maintenance agent suitable for super-hydrophilic coatings in view of the above technical status.

[0014] The fourth technical problem to be solved by the present invention is to provide an application of an environmentally friendly clean and maintenance agent in view of the above technical status.

[0015] The technical solution adopted by the present invention to solve the above first and second technical problems is as follows: An environmentally friendly clean and maintenance agent, characterized by comprising the following components and their weight ratios:

[0016]

[0017] The weight percentage of alkyl polyglycoside in the aforementioned aqueous solution of alkyl polyglycoside is 40 - 60%.

[0018] Preferably, the environmentally friendly clean and maintenance agent comprises the following components and their weight ratios:

[0019]

[0020]

[0021] The weight percentage of the alkyl polyglycoside in the aforementioned aqueous solution of alkyl polyglycoside is 45%-55%.

[0022] Preferably, the ammonium oxide is at least one of cocoamidopropylamine oxide, dodecyldimethylamine oxide, lauryldimethylamine oxide, cetyl dimethylamine oxide, and erucamidopropylamine oxide.

[0023] The technical solution adopted by the present invention to solve the above-mentioned third technical problem is: a preparation method of an environment-friendly cleaning and maintenance agent, which is characterized by including the following steps:

[0024] ① Take water, put silane coupling agent 4140 under stirring, after fully stirring, add neutral silica sol, and continue stirring to obtain a dispersion;

[0025] ② Add the aqueous solution of alkyl polyglycoside, ammonium oxide, limonene, and sodium polystyrene sulfonate to the dispersion in step ① in sequence, and make a mixed emulsion under stirring;

[0026] ③ Add polyetheramine D230 under stirring until the solution is fully mixed to obtain an environment-friendly cleaning and maintenance agent.

[0027] Preferably, the stirring speed when adding silane coupling agent 4140 in step ① is 700-900 r / min, and the best is 800 r / min; the stirring speed in step ② is 700-900 r / min, and the best is 800 r / min; the stirring speed in step ③ is 400-600 r / min, and the best is 500 r / min.

[0028] The technical solution adopted by the present invention to solve the above-mentioned fourth technical problem is: the application of the environment-friendly cleaning and maintenance agent in the maintenance of super-hydrophilic coatings on kitchen walls, tiles, and the surfaces of household appliances.

[0029] Compared with the prior art, the advantages of the present invention are as follows:

[0030] Taking limonene as the main solvent, because it itself has strong dissolving properties, it can dissolve oil stains, making the stains relatively loose. The polyetheramine has a large number of amino groups, which can combine with ester groups, oxides, and hydroxyl groups in the oil stains and play a certain dispersing role, making the oil stains have a higher degree of looseness.

[0031] Alkyl polyglycoside and ammonium oxide have excellent decontamination ability and can remove oil stains. At the same time, they can greatly reduce the surface tension of water, form dense foam during the actual spraying process, quickly penetrate and enter the interior of the oil stains, and have a certain emulsification ability, which can make the water-insoluble limonene form a stable emulsion dispersion state.

[0032] In the actual decontamination process, the limonene emulsion microparticles can be regarded as a decomposition unit. The limonene emulsion beads are wrapped by polyetheramine, alkyl glycoside, and ammonium oxide. When they act on the surface of oil stains, the surface amino groups, glycosides, and ammonium oxide act on the surface of the oil stains, making the wrapping on the surface of the emulsion loose and thus broken. After the limonene is released, it begins to dissolve the oil stains, and a large amount of free detergent in the solution will take away the oil stains. This has a good effect on cleaning the oil stains.

[0033] In the whole detergent composition, silica sol and silane coupling agent 4140 are used as hydrophilic curing agents. After hydrolysis, silane coupling agent 4140 adheres to the surface of silica sol and forms a hydrophilic (4140 functional group is polyethylene glycol group) package on the surface of silica sol. This can increase the water solubility and stability of the material. At the same time, if the surface needs to be wiped repeatedly during cleaning, the silicon oxide particles can be used as nano-abrasives to help remove stubborn stains and have a polishing effect on the surface of hard materials. In this way, the material will become brighter after cleaning. Similarly, due to physical friction, many fresh surfaces will be produced at the microscopic level. In this way, the silane coupling agent and numerous hydrophilic groups have the opportunity to stay on the surface of the material, supplementing a certain amount of hydrophilic groups for the hydrophilic coating, and achieving the effect of curing and enhancing the hydrophilicity of the surface. Even for ordinary hard surfaces, the hydrophilicity of the material surface will be enhanced to a certain extent, and the water retention of the material can be enhanced, which is conducive to the next surface cleaning. Sodium polystyrene sulfonate has many sulfonic acid groups, which can assist in emulsification and dispersion of limonene.

[0034] The cleaning and maintenance agent of the present invention can not only effectively clean kitchen fumes, but also maintain the super-hydrophilic coating, and has no irritating odor and is harmless to the environment. DETAILED DESCRIPTION

[0035] The present invention is further described in detail below with reference to the embodiments.

[0036] Step 1: Take 30 parts of water and add 0.8-4 parts of silane coupling agent 4140 under high-speed stirring at 800r / min. After sufficient stirring, add 1-4 parts of silica sol (neutral silica sol). After stirring for 4 hours, a dispersion 1 is obtained.

[0037] Step 2: Gradually add 28 - 46 parts of alkyl polyglycoside (50% aqueous solution), 4 - 8 parts of ammonium oxide (at least one of cocamidopropylamine oxide and cocamidopropylamine oxide), 1 - 4 parts of limonene, and 0.8 - 3 parts of sodium polystyrene sulfonate to the dispersion liquid 1, and make a mixed emulsion under the condition of high-speed stirring at 800 r / min.

[0038] Step 3: Add 0.8 - 3.5 polyetheramine D230 under the condition of low-speed stirring at 500 r / min until the solution is fully mixed to obtain a clean maintenance agent.

[0039] Table 1 shows the components and their weight ratios of each example.

[0040]

[0041] Table 2 shows the performance test results of each example:

[0042]

[0043] Test results: Examples 1 - 7 all have high stability and good stain cleaning performance, with the highest reaching 89.3%. At the same time, by comparing the hydrophilic angles before and after cleaning the hydrophilic and easy-to-clean coating, it can be seen that the hydrophilic angle of the material decreases significantly, and the hydrophilicity of the material is improved to a certain extent. This shows that the cleaner enhances the hydrophilicity of the material and has a certain maintenance effect. Comparative example 1 has a high cleaning efficiency, but after repeated cleaning for many times, the hydrophilic angle of its surface changes greatly, which is caused by the lack of hydrophilic particles inside the cleaning agent and the inability to supplement the dissolved hydrophilic substances.

[0044] Test method: Appearance, high and low temperature stability, and detergency are tested according to the test methods in GB / T35833 - 2018.

[0045] For the water contact angle test before and after cleaning, the same target pollutants (a mixture of lard, castor oil, and rapeseed oil = 1:1:1) as those in GB / T35833 - 2018 are coated on a self-made hydrophilic coating with stainless steel as the substrate. The cleaning agent is sprayed onto the surface of the pollutants, and after standing for 5 minutes, the material is wiped with a cleaning cloth on the surface, washed with water after wiping clean, and then dried.

[0046] Usage method: Directly spray onto the stain surface.
