Description

Technical Field

[0001] The invention relates to a permeation cleaning agent and application thereof, belonging to the technical field of automatic cleaning. Background Art

[0002] Glass-ceramic is also called ceramic glass. It has high structural strength but weak chemical corrosion resistance. Conventional glass cleaners may cause scratches, yellowing and other defects. In particular, etched glass has a concave-convex structure. Due to the surface tension of the liquid, the cleaner cannot enter the concave places, making it difficult to clean.

[0003] An acidic cleaning agent in the prior art has strong acidic cleaning penetration ability, but the acidic cleaning agent can only help cleaning, and cannot completely remove dirt. It needs to be combined with an alkaline cleaning agent to completely remove dirt. Another glass cleaning agent, adding nonionic surfactants and anionic surfactants, can reduce the surface tension of the cleaning agent. Although anionic surfactants have a strong ability to remove dirt, anionic surfactants are not easy to rinse. If there is any residue, due to its charged characteristics, it is easy to cause dust particles to be adsorbed after cleaning. There is also a glass cleaning agent, which includes nonionic surfactants, anionic surfactants and cationic surfactants. The three different types of surfactants are mixed, which is very likely to cause the solution to be turbid, and there will be charged particles on the surface of the glass after cleaning, resulting in the adsorption of dust and other dirt; there is also a cleaning agent that uses acetylene glycol as a surfactant to remove oil stains, but tetramethyldecynediol has a very low solubility in water. If only acetylene glycol is added, acetylene glycol will not be dissolved in the cleaning agent, and the advantages of acetylene glycol cannot be brought into play. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the first object of the present invention is to provide a penetrating cleaning agent, which has low surface tension and can quickly wet the surface of the etched glass substrate, thereby greatly improving the cleaning yield.

[0005] The second object of the present invention is to provide an application of the above-mentioned penetration cleaning agent.

[0006] The first object of the present invention can be achieved by adopting the following technical solution: a permeation cleaning agent, comprising the following active ingredients in parts by weight:

[0007]

[0008] Further, the following active ingredients are included by weight:

[0009]

[0010] Furthermore, the mass ratio of isomeric tridecanol polyoxyethylene ether to acetylene glycol surfactant is 1:8.

[0011] Further, the acetylene glycol surfactant includes at least one of tetramethyldecynediol, butynediol ethoxylate, 2,5,8,11-tetramethyl-5-decyn-4,7-diol, ethoxylate, hydroxypropyl propargyl ether and butynediol ethoxylate.

[0012] Further, the complexing agent includes at least one of EDTA-2Na, HEDP-2Na, sodium gluconate and sodium citrate.

[0013] Furthermore, the complexing agent includes EDTA-2Na, HEDP-2Na and sodium gluconate or sodium citrate; the weight parts of EDTA-2Na, HEDP-2Na, sodium gluconate or sodium citrate are 1-5 parts of EDTA-2Na, 1-5 parts of HEDP-2Na, and 3-10 parts of sodium gluconate or sodium citrate based on the total weight parts of the osmotic cleaning reagent.

[0014] Further, the pH adjuster includes at least one of potassium carbonate and triethanolamine.

[0015] Furthermore, the pH regulator is potassium carbonate and triethanolamine; the weight proportions of potassium carbonate and triethanolamine are 5-10 parts and 2-8 parts of triethanolamine, based on the total weight proportions of the penetration cleaning reagent.

[0016] The second object of the present invention can be achieved by adopting the following technical scheme: application of a penetrating cleaning reagent, using the penetrating cleaning reagent as described above to clean the etched glass; immersing the etched glass in the penetrating cleaning reagent, cleaning it under ultrasonic or spray brushing conditions, and then spraying it with pure water.

[0017] Further, the etched glass is immersed in a penetrating cleaning agent at a temperature of 45-55°C.

[0018] The formulation design principle of the present invention is as follows:

[0019] The prior art does not use acetylene glycol surfactants to clean glass cleaning agents, and also lacks the ratio of acetylene glycol surfactants to conventional surfactants. Therefore, there is still room for improvement and development in the research and development of improving the cleaning yield of microcrystalline glass after etching.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The addition of acetylene glycol surfactants to the penetrating cleaning reagent of the present invention not only reduces the dynamic surface tension of the cleaning reagent, but also inhibits the foam of the isomeric tridecanol polyoxyethylene ether surfactant;

[0022] 2. The penetrating cleaning agent of the present invention can greatly improve the wetting, defoaming, dispersing, flowing and leveling capabilities of the penetrating cleaning agent by using a very small amount of acetylene glycol surfactant, and can reduce the surface tension of the liquid to about 35. It is particularly suitable for combining with isomeric tridecanol polyoxyethylene ether surfactant and being used in a cleaning machine, which can quickly wet the etched glass surface and prevent the generated foam from overflowing the water storage tank;

[0023] 3. The penetrating cleaning agent of the present invention is used for cleaning glass. It has low surface tension and can be used to clean etched glass. It produces almost no foam, can quickly penetrate into gaps, and has a high cleaning ability. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0030] A penetrating cleaning agent, comprising the following active ingredients in parts by weight as shown in Table 1:

[0031] Table 1 Active ingredients of penetrant cleaning agents

[0032]

[0033] Among them, the acetylene glycol surfactant includes at least one of tetramethyldecynediol, butynediol ethoxylate, 2,5,8,11-tetramethyl-5-decynediol-4,7-diol, ethoxylate, hydroxypropyl propargyl ether and butynediol ethoxylate. Conventional acetylene glycols have poor water solubility. Ethoxylating or adding EO (ethylene oxide) or PO (propylene oxide) groups to acetylene glycols can not only retain the completely foam-free characteristics of acetylene glycols, but also increase water solubility, which is particularly suitable for the needs of etching glass cleaning.

[0034] Since microcrystalline glass is not resistant to strong acids and alkalis, excessive alkalinity may cause the glass to turn yellow and cause the Lab value to shift. Therefore, carbonates, especially potassium carbonate, are used as pH adjusters. Compared with sodium carbonate, potassium carbonate has a higher solubility and is easier to rinse clean later, leaving no residue on the surface.

[0035] The method of using the penetrating cleaning agent is as follows: immerse the etched glass in the penetrating cleaning agent at a temperature of 45-55°C, clean it under ultrasonic or spray brushing conditions, and then spray it with pure water.

[0036] The active ingredients and weight parts of the comparative example:

[0037] Comparative Example 1: 5-50 parts of organic acid (citric acid and oxalic acid); 1-6 parts of nonionic surfactant (fatty acid methyl ester ethoxylate and lauryl alcohol polyoxyethylene polyoxypropylene ether); 1-5 parts of anionic surfactant (fatty acid methyl ester ethoxylate sulfonate); 1-5 parts of thickener. Acidic cleaning has strong penetration ability, but acidic cleaning agents can only help cleaning, and cannot completely remove dirt. Alkaline cleaning agents are needed to completely remove dirt.

[0038] Comparative Example 2: 46-76.5 parts of low surface tension activated water; 23-53 parts of antifreeze degreasing agent; 0.1-0.5 parts of nonionic surfactant; 0.1-0.3 parts of anionic surfactant; 0.1-0.2 parts of corrosion inhibitor; 0.1-0.5 parts of lubricant; 0.1-0.2 parts of antiseptic and mildew inhibitor. Adding nonionic surfactant and anionic surfactant can reduce the surface tension of the cleaning agent, and anionic surfactant has a strong ability to remove dirt, but anionic surfactant is not easy to rinse. If there is any residue, it is easy to adsorb dust particles after cleaning due to its charged characteristics.

[0039] Comparative Example 3: 3-10 parts of citric acid; 3-8 parts of citrate; 0-2 parts of thickener; 0.05-1 parts of anionic surfactant; 0.05-1 parts of cationic surfactant; 0.05-1 parts of nonionic surfactant; 0.1-2 parts of chelating agent; 0.1-2 parts of nitrate; 0.1-2 parts of hydrogen peroxide; 0.1-2 parts of cosolvent. Mixing three different types of surfactants will cause the solution to become turbid, and there will be charged particles on the surface of the cleaned glass, which will adsorb dirt such as dust.

[0040] Comparative Example 4: 3 parts of EDTA-2Na; 3 parts of HEDP-2Na; 8 parts of sodium gluconate; 8 parts of potassium carbonate; 3 parts of triethanolamine.

[0041] Comparative Example 5: 1.6 parts of isomeric tridecanol polyoxyethylene ether; 3 parts of EDTA-2Na; HEDP-2Na

[0042] 3 parts; sodium gluconate 8 parts; potassium carbonate 8 parts; triethanolamine 3 parts.

[0043] Table 2: Composition weight parts of the embodiment

[0044]

[0045] The etched glass is immersed in a penetrating cleaning agent at a temperature of 45-55°C, cleaned under ultrasonic or spray brushing conditions, and then sprayed with pure water.

[0046] Performance testing:

[0047] Surface tension test: The results are as follows Figure 1 shown.

[0048] Cleaning cleanliness yield rate: After cleaning, the sample to be tested is tested using AOI equipment (universal cover glass testing equipment) to test the surface cleanliness of the microcrystalline glass (10 points are taken, the diameter of each point is 1mm, and the average value of the 10 points is tested). If the average value of RFU (correlated fluorescence unit) obtained by the test is ≤50RFU, the cleanliness is qualified, otherwise it is unqualified;

[0049] Yield (number of glasses with an average RFU value ≤ 50 / total number of glasses input) × 100%.

[0050] Table 3 Cleaning cleanliness yield of comparative example and embodiment

[0051] example Cleanliness Comparative Example 1 56.4％ Comparative Example 2 31.8％ Comparative Example 3 30.7％ Comparative Example 4 75.2％ Comparative Example 5 84.5％ Example 1 99.3％ Example 2 93.1％ Example 3 99.8％ Example 4 99.5％ Example 5 92.7％

[0052] From the above results, it can be seen that the cleaning yields of Examples 1 / 3 / 4 are all above 99%. Among them, since no acetylene alcohol surfactant is added to Comparative Examples 4 and 5, the cleaning agent cannot quickly penetrate into the glass surface, and the cleaning yield is low. The cleaning yields of Examples 2 and 5 are lower than those of Examples 1 / 3 / 4 because the ratio of acetylene glycol surfactants to isomeric tridecanol polyoxyethylene ether cannot reflect the best technical effect. When the ratio of conventional surfactants to acetylene alcohol surfactants is 8:1, the cleaning yield is optimal.

[0053] Etched glass cleaning: Figure 2 and 3 They are respectively a micrograph (150 times) of the glass surface after cleaning with Comparative Example 5 and a schematic diagram of the cleaning agent on the glass surface. Figure 4 and 5 The following are the micrographs (150 times) of the glass surface after cleaning with Example 3 and the schematic diagram of the cleaning agent on the glass surface. After cleaning with Comparative Example 5, the cleaning agent cannot penetrate into the glass surface due to the lack of wetting ability. Figure 2 As shown in Figure 2, a layer of etching byproducts remains on the glass surface, such as Figure 3As shown in FIG. 1 , due to the high surface tension, the cleaning solution cannot penetrate into the recessed position, resulting in the dirt in the recessed position not being contacted by the cleaning solution, which leads to poor cleaning. In the cleaning of Example 3, the cleaning agent is added with an acetylene alcohol surfactant, which can quickly wet the etched glass surface. Figure 4 As shown, there is no by-product residue on the glass surface after cleaning, and the surface cleanliness meets the standard.

[0054] For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and concepts described above, and all of these changes and modifications should fall within the protection scope of the claims of the present invention.
