Description

TECHNICAL FIELD

[0002] In the process of glass, in order to improve the surface performance of the glass, a functional film layer is usually formed on the surface of the glass, wherein the AF film (anti-fingerprint film) is a commonly used functional film layer. By forming an AF film on the surface of the glass, good dustproof, anti-fingerprint, oil stain-proof effect can be obtained, so that the surface of the glass can be kept in a relatively clean state.

[0003] When forming an AF film on the surface of the glass, spraying or electroplating is a commonly used way. By spraying or electroplating, an AF film with good effect can be formed on the surface of the glass, but these processing methods are easy to leave a certain amount of oily raw material (referred to as AF oil) on the surface of the AF film. When using a traditional cleaning agent for cleaning, the residual AF oil will bring some difficulties to the cleaning of the glass, mainly manifested as that the AF oil dissolved by the cleaning agent is easy to re-precipitate, and the re-precipitated AF oil will bring some troubles to the cleaning of the glass. For example, the re-precipitated AF oil adheres to the surface of the cleaning equipment, and it is difficult to remove the AF oil adhered to the surface of the cleaning equipment, which will increase the difficulty of equipment maintenance, and may also affect the normal operation of the glass cleaning process, and reduce the cleaning efficiency of the glass.

[0037] In order to make the above objectives, features and advantages of the present application more clear and comprehensible, the detailed description of the specific embodiments of the present application is given below. In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other different ways than those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0039] An embodiment of the present application provides an aqueous glass cleaning agent, and the preparation raw materials thereof include the following components in the following mass percentages: fatty alcohol polyoxyethylene ether 0% to 0.5%, alkoxy fatty alcohol 0% to 0.2%, non-ionic modified fatty alcohol polyoxyethylene ether 1% to 3%, and water in the balance. In this embodiment, the glass cleaning agent is mainly water, which can effectively dissolve and remove AF oil, and after the AF oil is dissolved in the aqueous glass cleaning agent, the AF oil will not re-precipitate.

[0040] Meanwhile, the cleaning product after the glass is cleaned by the aqueous glass cleaning agent of this embodiment mainly appears in the form of crystalline snow-like white flocculent matter which is easy to clean and remove, that is, the cleaning product after the glass is cleaned by the aqueous glass cleaning agent of this embodiment is easy to remove. And in the cleaning agent in which the AF oil is dissolved, as the AF oil will not re-precipitate with the extension of time, the AF oil will not adhere to the surface of the cleaning equipment, thereby effectively reducing the difficulty of removing the cleaning product. Meanwhile, after the glass cleaned by the above aqueous glass cleaning agent is dried, the problem of water marks appearing on the surface of the glass is well improved.

[0041] It can be understood that the AF film is a functional film layer that is more commonly used on the surface of glass. By forming an AF film on the surface of glass, the glass can have good dustproof, anti-fingerprint, and anti-oil functions, so that the surface of the glass can be kept relatively clean. When forming the AF film, AF oil is a commonly used raw material. After using the AF oil to form the AF film on the surface of the glass, a certain amount of AF oil will inevitably remain on the surface of the glass. At this time, the glass surface is usually cleaned to remove the residual AF oil. However, when the glass is subsequently cleaned using traditional cleaning agents such as ethanol, isopropyl alcohol, etc., the residual AF oil on the surface of the glass is easy to re-precipitate in the cleaning agent. The re-precipitated AF oil will adhere to the surface of the cleaning equipment, and the AF oil adhering to the surface of the cleaning equipment is difficult to remove, thereby increasing the difficulty of maintaining the equipment. Moreover, when there is a large amount of AF oil adhering, the maintenance frequency of the equipment will be increased, which will affect the normal operation of the glass cleaning process and reduce the cleaning efficiency of the glass.

[0042] The inventors of the present application have found that when the aqueous glass cleaner in the present application is used to clean the glass, the aqueous glass cleaner has good solubility for the AF oil, and the aqueous glass cleaner will first dissolve the AF oil on the surface of the glass to remove the AF oil from the surface of the glass. After the AF oil is dissolved in the aqueous glass cleaner in the present application, the AF oil will not re-precipitate over time. Moreover, the cleaning product after the glass is cleaned by the aqueous glass cleaner in the present application mainly appears in the form of crystalline snow-like white flocculent material that is easy to clean, and the AF oil will not re-precipitate and adhere to the surface of the cleaning equipment. When the aqueous glass cleaner in the present application is used to clean the glass, when the cleaning agent needs to be replaced or when part of the cleaning agent needs to be discharged, the flocculent cleaning product will be discharged together with the cleaning agent and will not easily remain in the cleaning equipment, which can greatly improve the replacement efficiency of the cleaning agent, reduce the maintenance difficulty of the cleaning equipment, and improve the cleaning efficiency of the glass. If a small amount of cleaning product is not discharged together with the cleaning agent when the cleaning agent is discharged, the cleaning equipment can be easily flushed with water to flush out the small amount of cleaning product.

[0043] Further, the aqueous glass cleaner in the present application has a pH value of 6-8, which is a neutral cleaning agent and will not adversely affect the performance of the glass. In the cleaning process, it is beneficial to maintain the stability of the glass performance.

The cleaning method was to spray the cleaning solution to the surface of the glass. The cleaning temperature was 38°C to 45°C. The transmission speed of the glass was 2 m / min to 2.2 m / min. The spraying pressure was 0.8 kg / cm 2 to 1.0 kg / cm 2 . The oil residue in the cleaning tank after cleaning was shown in Table 2. The glass after cleaning was dried, and the water mark residue on the surface of the glass after drying was shown in Table 2. It can be seen from Table 2 that after cleaning, there was no oil residue in the cleaning tank and no water mark residue on the surface of the glass in Examples 1 to 8. There was no oil residue in the cleaning tank and there was water mark residue on the surface of the glass in Examples 9 to 11. There was oil residue in the cleaning tank and no water mark residue on the surface of the glass in Comparative Example 1. There was oil residue in the cleaning tank and water mark residue on the surface of the glass in Comparative Examples 2 to 5.
