Description

Technical Field

[0001] The present invention relates to the field of anti-fog cleaning products, and in particular to an anti-fog cleaning composition and an application method thereof. Background Art

[0002] As we all know, lenses tend to fog up easily when exposed to cold or hot air, such as when driving in the rain, eating hot pot while wearing glasses, or breathing on the mirror in winter. This is primarily due to the temperature difference between hot and cold, which causes a layer of tiny water droplets to form on the lens surface, known as mist. If this mist is not removed promptly, it can seriously affect vision, especially for drivers, making it difficult to see the road ahead and behind, potentially leading to traffic accidents. There are many conventional anti-fog products for glass and lenses, but their anti-fog effectiveness generally varies significantly.

[0003] Chinese Patent No. 201010149136.0 discloses anti-fog cleaning wipes for automotive glass and a method for preparing the same. The wipes are composed of an anti-fog cleaning solution and a non-woven fabric carrier that absorbs the anti-fog cleaning solution. The anti-fog cleaning solution, per 100 parts by weight, comprises the following components in the following proportions: (a) 0.5-5.0% surfactant; (b) 0.05-2% polyacrylic acid cross-linked polymer; (c) 0.2-1.0% water-soluble silicone oil; (d) 0-1.0% triethanolamine; (e) 1-10% isopropyl alcohol; and (f) the balance, pure water. The anti-fog cleaning wipes disclosed in this patent are suitable for use inside cars, but testing has found that these wipes easily leave marks on the glass after wiping, leaving it looking unclean and impaired visibility.

[0004] Chinese Patent No. 201711132898.8 discloses an anti-fog cleaning solution for glasses and its preparation method. The raw materials for preparing the anti-fog cleaning solution for glasses include, by weight, 10-15 parts of ethyl orthosilicate, 10-15 parts of vinyl triethoxysilane, 0.5-2 parts of nano-titanium dioxide, 40-50 parts of anhydrous ethanol, 1-5 parts of potassium sorbate, 0.5-3 parts of a surfactant, and 5-10 parts of deionized water. The anti-fog cleaning solution prepared by the present invention has a good anti-fog effect, a long anti-fog effect, and a significant cleaning effect on glasses. It is simple to use and does not cause damage to the glasses. The raw materials are cheap and readily available, and the preparation method is simple, making it suitable for large-scale production. However, after spraying the anti-fog cleaning solution on the glasses, it needs to be wiped with a paper towel or glasses cloth to quickly dry the glasses, making it inconvenient to use. Secondly, the spraying will leave a rainbow mark on the lenses, affecting the visual effect of the lenses. Summary of the Invention

[0005] Therefore, in response to the above problems, the present invention provides an anti-fog cleaning composition and an application method thereof, which solve the defects of the prior art anti-fog cleaning products that leave traces after use and have poor anti-fog cleaning effects.

[0006] To achieve the above objectives, the present invention adopts the following technical scheme: an anti-fog cleaning composition, comprising the following raw materials in parts by weight: 0.1-2 parts of a silicone composition, 1-5 parts of propylene polyether, 1-5 parts of polysiloxane, 0.1-1.0 parts of Tween-80, 0.1-1.0 parts of fatty alcohol polyoxyethylene ether, 0.1-1.0 parts of a preservative, 10-40 parts of a special solvent, 0.01-0.2 parts of polyvinyl pyrrolidone, and 44.8-87.59 parts of deionized water.

[0007] A further improvement is that the silicone composition is compounded by fluorocarbon-modified silicone oil, amino-modified polyether silicone and propylene glycol in a weight ratio of 1:1:1-5.

[0008] A further improvement is that the special solvent is prepared by compounding ethanol and isopropanol at a ratio of 0.8-1.2:1-1.2.

[0009] A further improvement is that the special solvent is prepared by mixing ethanol and isopropanol in a ratio of 1:1.

[0010] A further improvement is that it also contains 0.1-5 parts by weight of carbomer resin.

[0011] A method for applying an anti-fog cleaning composition comprises the following application steps:

[0012] (1) Select a wet wipes carrier;

[0013] (2) The anti-fog cleaning composition described above is mixed with the wet wipe carrier in a weight ratio of 1:0.7-1.5 to obtain anti-fog cleaning wet wipes.

[0014] A further improvement is that the wet wipes carrier is any one of pure cotton cloth, viscose fiber cloth, SAF super absorbent fiber cloth, and polyester cloth.

[0015] A further improvement is that the anti-fog cleaning composition in step (2) is mixed with the wet wipes by spraying it evenly on the wet wipes carrier.

[0016] A further improvement is that the preparation method of the anti-fog cleaning composition is as follows: (1) weighing each raw material according to the amount described, and sequentially adding the silicone composition, propylene polyether, polysiloxane, Tween-80, fatty alcohol polyoxyethylene ether, preservative, special solvent, polyvinyl pyrrolidone, and deionized water into a reaction tank, and stirring evenly to obtain a mixture; (2) adjusting the pH value of the mixture to make pH = 7-7.8.

[0017] A further improvement is that the pH value of the mixture in step (2) is adjusted by triethanolamine.

[0018] By adopting the above technical solution, the beneficial effects of the present invention are:

[0019] 1. The present invention utilizes a fluorinated silicone composition to improve the hydrophilicity of lens surfaces and prevent the formation of water droplets. The volatility of the specially formulated solvent rapidly removes moisture from the lens, rapidly forming a film and maintaining a long-lasting cleansing and anti-fog effect. However, using ethanol or isopropyl alcohol alone can easily leave marks or rainbow stains on the lens, affecting its effectiveness.

[0020] 2. Furthermore, when the special solvent is compounded by ethanol and isopropyl alcohol in a weight ratio of 1:1, the product can achieve a quick-drying and traceless effect after wiping the lens.

[0021] 3. The present invention is applicable to glass lenses and automobile glass.

[0022] 4. The silicone composition of the present invention is compounded by fluorocarbon-modified silicone oil, amino-modified polyether silicone and propylene glycol in a weight ratio of 1:1:1-5. It can provide a lower surface tension for the wiped object, has good film-forming uniformity, and can evaporate quickly.

[0023] 5. The anti-fog cleaning composition of the present invention is combined with a wet wipe carrier to obtain an anti-fog cleaning wet wipe that is easy to carry and does not require the tedious operation of spraying first and then wiping. After wiping eyeglass lenses or car glass, it has the characteristics of quick drying, good anti-fog effect, and excellent cleaning performance.

[0024] 6. The anti-fog cleaning composition of the present invention also contains a certain weight portion of carbomer resin, which can provide a further film-forming effect and further extend the anti-fog time. DETAILED DESCRIPTION

From the second time onward, each repetition is equivalent to one day of anti-fog performance.

[0045] 2) Low-temperature anti-fog performance: Wipe both sides of a clean, dry glass with the prepared anti-fog wipes and place it in a refrigerator at 0°C to 5°C. Measure the time from the moment fogging occurs to calculate the low-temperature anti-fog time.

[0046] 3) Light Transmittance: Use anti-fog wipes to coat one side of a glass slide with an anti-fog agent. Measure the absorbance of the coated slide and a blank slide using a spectrophotometer. Measure the light transmittance of the slide treated with the anti-fog wipes and compare it to the transmittance of the untreated slide to obtain a relative value.

[0047] 4) Surface Leveling: Visually inspect the surface of a clean glass sheet by wiping it with an anti-fog wipe. Place the glass sheet vertically for 5 minutes and then observe the surface. Determine the surface using the following criteria: A - Smooth surface without any marks, completely transparent; B - Slight marks on the surface, no effect on transparency; C - Spots and partial marks on the surface, slightly opaque; D - Significant marks on the surface, affecting the light transmittance of the glass.
