Description

Technical Field

[0001] This invention relates to the field of cleaning agents, and in particular to a method for preparing a cleaning agent for penetrating 502 glue on ceramics and a cleaning process thereof. Background Technology

[0002] Cyanoacrylate resin glue (502 glue) is a commonly used adhesive in ceramic restoration. It is a glue that polymerizes rapidly upon contact with moisture or water molecules in the air. Once cured, it is difficult to dissolve. This adhesive is widely used in museums, archaeological sites, and other cultural relic protection units. However, because unmodified 502 glue generally has high permeability, improper use may cause the glue to seep into the surface of the pottery, resulting in glue stains that are difficult to remove and damaging the original appearance of the pottery.

[0003] Pottery, as a common type of ancient relic, is fired at a relatively low temperature and mostly lacks a solid glaze. Its surface is porous and easily absorbs liquids. Highly permeable adhesives like super glue (502) can be absorbed into it, leaving dark-colored glue residue. Current removal methods mainly include mechanical cleaning, heat treatment, and solvent cleaning.

[0004] 1. Mechanical cleaning is simple and direct, requiring only scraping or grinding to remove visible glue from the surface. However, due to the porous nature of pottery, the glue often seeps into the interior of the pottery body, and hasty cleaning will only damage the artifact.

[0005] 2. Heat treatment refers to continuously heating the object to be cleaned at a temperature above 200°C to soften the adhesive and then peel it off mechanically. However, since 502 glue does not have complete volatility at high temperatures, it will only leave black carbon residue after high-temperature treatment, so this method is not suitable for cleaning.

[0006] 3. Solvent cleaning involves using organic solvents to soften and expand the adhesive. This method is suitable for materials like porcelain, which are fired at high temperatures, have good texture, and high porosity. However, for earthenware, the expansion of the adhesive during softening may rupture the portion of the adhesive that has penetrated the surface, causing irreversible damage to the earthenware surface. (This invention also uses organic solvents. Does it involve softening and expansion? Or does the alternating treatment with strong alkali and organic solvents prevent this damage?)

[0007] It is evident that the current technology for cleaning ceramics with high-penetration 502 glue has certain shortcomings and cannot meet the relevant requirements. Summary of the Invention

[0008] The purpose of this invention is to provide a method for preparing a 502 glue-penetrating cleaning agent for ceramics and a cleaning process to solve the problems mentioned in the background art.

[0009] The technical solution adopted in this invention is:

[0010] A method for preparing a 502 glue-impregnating cleaning agent for ceramics and a cleaning process thereof.

[0011] S1: Weigh deionized water, sodium hydroxide, dimethylformamide, and hydroxypropyl methylcellulose (HPMC);

[0012] S2: Mix deionized water with sufficient hydroxypropyl methylcellulose (HPMC) to ensure that the two are mixed evenly;

[0013] S3: Add sodium hydroxide and dimethylformamide (DMF) to the above solution, stir and mix to form the first component solution, and then let it stand;

[0014] S4: Add Carbomer 934 to the above solution in proportion and mix and stir evenly to make it into a uniform gel, thus obtaining the first component.

[0015] S5: Weigh deionized water, acetone, and polyethylene glycol, and mix them at room temperature to obtain the second component.

[0016] Optionally, alternating treatment with strong alkali and organic solvents can be used.

[0017] Optional, the composition by weight percentage is: 8-15 parts deionized water, 2 parts sodium hydroxide, 1-2 parts dimethylformamide (DMF), 3-5 parts carbomer 934; 5-6 parts acetone, 3-5 parts polyethylene glycol, and 1-2 parts hydroxypropyl methylcellulose (HPMC).

[0018] Optionally, the settling time in S3 is 5 minutes.

[0019] Optionally, the mixing time in step S5 is 5 minutes.

[0020] A cleaning process for using a 502 glue-penetrating cleaning agent on ceramics.

[0021] Step 1: Apply the first component of the cleaning agent, which has been mixed evenly, to the adhesive residue that needs to be cleaned. After sealing it with plastic wrap or aluminum foil at room temperature, wait 1-2 hours and then wipe it off with a paper towel.

[0022] Step 2: Wet a non-woven fabric or degreased cotton with the second component cleaning agent and cover it with the area to be cleaned by the first component cleaning agent. After sealing it with plastic wrap at room temperature, remove the non-woven fabric or degreased cotton with the second component cleaning agent after 0.5-1 hours. Repeat the application until there is no stain on the surface to complete the cleaning.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This cleaning agent effectively removes 502 glue that has penetrated deep into the ceramic body, resulting in a thorough cleaning. Simultaneously, it minimizes damage to the ceramic surface during use, making it particularly suitable for protecting fragile ceramics. Furthermore, by controlling the penetrability and range of action of the cleaning agent, this invention allows for precise control of the cleaning process, avoiding unnecessary impact on surrounding areas, saving cleaning time, and improving cleaning efficiency. The production method of this cleaning agent is scientifically sound and easy to implement, thus possessing broad market prospects. Detailed Implementation

[0025] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship that is commonly used when the product of this invention is in use, or the orientation or positional relationship that is commonly understood by those skilled in the art. They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Currently available technologies offer several advantages. Mechanical cleaning is simple and direct, requiring only scraping or grinding to remove visible glue. However, due to the porous nature of pottery, the glue often seeps into the clay body, and hasty cleaning can damage the artifact. Heat treatment involves continuously heating the object to over 200°C to soften the adhesive, allowing for mechanical removal. However, since 502 glue does not fully volatilize at high temperatures, it leaves only black carbon residue after treatment, making this method unsuitable. Solvent cleaning uses organic solvents to soften and expand the adhesive. This method is suitable for materials like porcelain, which are fired at high temperatures, have good texture, and high porosity. However, for pottery, the expansion of the adhesive during softening may rupture the surface, causing irreversible damage. This invention provides a method for preparing a 502 glue-penetrating cleaning agent for pottery and a cleaning process.
