Description

Technical Field

[0001] This invention belongs to the field of cleaning products technology, specifically relating to a high-temperature degreasing stove cleaner, its preparation method, and its application. Background Technology

[0002] Kitchen grease has a complex composition, mainly consisting of high-temperature grease, charred residue, and food scraps. Commercially available stove cleaners are primarily highly alkaline liquids, supplemented with low-foaming, highly alkali-resistant surfactants and highly grease-dissolving organic solvents to quickly penetrate, emulsify, and dissolve grease and charred deposits. However, commercial kitchens, in order to improve serving efficiency, use stainless steel cookware with heating functions that include grilling, heating, and heat preservation. The grease evaporates at high temperatures, making it easier for the resulting grease to form sticky oxidized polymers.

[0003] For example, Chinese patent application CN103045389A discloses a stove cleaner composed of the following raw materials in parts by weight: 60 parts water, 4-6 parts sodium metasilicate pentahydrate, 1-2 parts iron-sodium diethylenetriaminepentaacetic acid complex, 6-10 parts tripropylene glycol butyl ether, 6-10 parts tripropylene glycol methyl ether, 2-4 parts 2-amino-2-methyl-1-propanol, and 1-3 parts C14-16 alkenyl sulfonate sodium. Although this stove cleaner has a good grease removal effect, it has not undergone high-temperature degreasing tests, and its suitability for high-temperature degreasing is unpredictable.

[0004] Chinese patent application CN110819474A discloses a commercial kitchen grease cleaner, cleaning device, and cleaning method. The cleaner comprises the following components by weight percentage: 40%–55% Na₂CO₃, 5%–18% NaHCO₃, 3%–15% sodium metasilicate, 5%–15% fatty alcohol polyoxyethylene ether, 1%–12% SiO₂, and 1%–5% sodium dodecylbenzenesulfonate. The cleaning device heats the cleaning solution to 70-80 degrees Celsius, then immerses the greased kitchenware in the solution before removing it. This cleaning method is cumbersome and unsuitable for large, difficult-to-disassemble kitchenware.

[0005] In conclusion, it is urgent to develop a stove cleaner that is simple to use, suitable for high-temperature degreasing, and has good cleaning and degreasing effects on commercial kitchenware. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a high-temperature degreasing stove cleaner, its preparation method, and its application. The high-temperature degreasing stove cleaner provided by this invention not only offers a simple cleaning method and is suitable for high-temperature degreasing, exhibiting excellent cleaning and degreasing effects on commercial kitchenware, but also boasts high safety and is non-corrosive to metals; its raw material composition is simple, requiring no defoamer.

[0007] The technical solution of this invention is: A high-temperature degreasing stove cleaner comprises the following components and their mass fractions: 11-33 parts alkaline additive, 1-2 parts hydroxyethylidene diphosphate, 3-6 parts nonionic surfactant, 4-8 parts solvent, 1-3 parts solubilizer, 1-3 parts sodium xylenesulfonate, and 45-79 parts water; wherein the solvent includes ethylene glycol monobutyl ether and diethylene glycol ethyl ether.

[0008] Furthermore, the high-temperature degreasing stove cleaner comprises the following components and their mass fractions: 33 parts alkaline additive, 1 part hydroxyethylidene diphosphate, 5 parts nonionic surfactant, 8 parts solvent, 3 parts solubilizer, 3 parts sodium xylenesulfonate, and 47 parts water.

[0009] Furthermore, the mass concentration of the hydroxyethylidene diphosphate (i.e., hydroxyethylidene diphosphonic acid, HEDP) is 60%.

[0010] Furthermore, the alkaline additive is composed of sodium hydroxide and sodium silicate in a mass ratio of 10-30:1-3.

[0011] Furthermore, the alkaline additive is composed of sodium hydroxide and sodium silicate in a mass ratio of 30:3.

[0012] Furthermore, the mass concentration of the sodium hydroxide is 32%.

[0013] One of the core contradictions in commercial kitchen appliance cleaning is that "strong alkalinity requires efficient saponification of greases, but it easily corrodes metal parts (such as stainless steel stove heads and cast iron supports)." Sodium hydroxide is a strong alkaline component that can quickly react with animal and vegetable oils to produce soluble soap. However, when used alone (even at low concentrations), its corrosion rate on metals increases significantly at high temperatures (commercial kitchen appliance cleaning often involves residual heat from stoves). Sodium silicate not only provides weak alkalinity to assist saponification but also forms a silica-oxygen protective film on the metal surface. However, excessive addition can lead to a "white frost" residue after cleaning, which increases the burden of subsequent wiping. This invention, through numerous creative experiments, has discovered that using a compound of sodium hydroxide and sodium silicate in a mass ratio of 10-30:1-3 as an alkaline auxiliary agent not only ensures saponification efficiency but also inhibits corrosion and leaves no residue, achieving a balance between saponification efficiency and corrosion risk.

[0014] Furthermore, the nonionic surfactant is a fatty alcohol polyoxyethylene ether.

[0015] Commercial kitchenware grease, due to prolonged high-temperature baking, forms a double-layer structure of "outer carbonized film + inner grease layer," which ordinary surfactants struggle to penetrate. The fatty alcohol polyoxyethylene ether added in this invention can adapt to the interfacial tension requirements of the "oil-water-carbonized film"—its polyoxyethylene chains (hydrophilic segments) can quickly wet the surface of the carbonized film, while the fatty alcohol chains can penetrate to the interface between the inner grease and metal, weakening the adhesion of the grease. Extensive creative experiments have revealed that adding too little fatty alcohol polyoxyethylene ether to the formulation results in insufficient penetration, while adding too much, although increasing penetration, generates excessive foam (commercial cleaning requires low foaming to avoid clogging stove vents), necessitating the addition of defoamers, thus increasing formulation complexity. In this invention, the amount of fatty alcohol polyoxyethylene ether in the formulation is controlled at 3-6 parts, ensuring penetration without requiring additional defoamers.

[0016] Furthermore, fatty alcohol polyoxyethylene ethers are easily oxidized and degraded in alkaline systems, leading to a decrease in surface activity. The sodium silicate added in this invention can also stabilize the system pH, reduce the oxidative effect of sodium hydroxide on the surfactant, and ensure stable surface activity during the cleaning process.

[0017] Furthermore, the solvent is composed of ethylene glycol monobutyl ether and diethylene glycol ethyl ether in a mass ratio of 2-4:2-4.

[0018] The burnt residue in grease from commercial kitchen utensils requires highly polar solvents to dissolve. This invention has found that while ethylene glycol monobutyl ether (EDGME) dissolves quickly, its high volatility under the residual heat of commercial stoves leads to insufficient solvent in the later stages of cleaning. Conversely, while diethylene glycol ethyl ether (DGE) has a lower volatility, its dissolution rate is slow. This invention creatively combines EEGME and DGE, improving both the dissolution rate and the performance in dissolving edible oils and rinsing, while simultaneously reducing high-temperature volatility, achieving a balance between rapid dissolution and low volatility.

[0019] Furthermore, the solubilizer is glycerol.

[0020] The glycerol added in this invention slows down solvent evaporation at higher temperatures and is non-corrosive to metals. However, the amount of glycerol in the formulation must be strictly controlled: if it is less than 1 part, the solvent evaporation rate is still high; if it is more than 3 parts, it will increase the viscosity of the system, making it difficult for the cleaning agent to be sprayed or flow, affecting penetration into crevices. The specific combination of solvent and glycerol in this invention is the optimal solution obtained after extensive viscosity-evaporation-solubility testing. Moreover, the specific combination of solvent and glycerol in this invention can also reduce the binding force between various components of grease and between grease and solid surfaces, enhancing the grease removal ability of the stove cleaner.

[0021] Furthermore, the mass concentration of the sodium xylenesulfonate is 40%.

[0022] This invention also provides a method for preparing the above-mentioned high-temperature degreasing stove cleaner, comprising the following steps: Dissolve the alkaline additive and hydroxyethylidene diphosphate in water, and after the solution is clear, add the nonionic surfactant, solvent, solubilizer and sodium xylenesulfonate in sequence, and mix well to obtain the final product.

[0023] Compared with the prior art, the present invention has the following advantages: (1) The present invention has a good effect on cleaning and removing grease from commercial kitchen utensils, bringing convenience to the cleaning of kitchen utensils in commercial kitchens.

[0024] (2) The kitchen utensils in the commercial kitchen have heating functions. Staff can directly use the heating function of the utensils to soften the oil stains, and then use stove cleaner. This not only makes it convenient and quick to clean the oil stains on the kitchen utensils, but also brings convenience to the staff.

[0025] (3) The stove cleaner of the present invention is highly safe and non-corrosive to metals.

[0026] (4) The raw material composition of the present invention is simple and no defoamer needs to be added. Attached Figure Description

[0045] 2. Experimental Method: A 10cm*5cm stainless steel sheet was weighed (W1). A layer of approximately 0.3g of dirt was coated onto the steel sheet and baked at 105℃ for 4 hours (W2). 200g of stove cleaner was placed in a 300mL beaker and kept at a constant temperature of 80℃ in a water bath.

Stop heating. Once the iron plate surface temperature has dropped to 60-80℃, pour in 40mL of stove cleaner. Gently scrape the cleaner with a scraper to allow the liquid to remain on the grease. After 10 minutes, rinse the plate surface with 1500mL of clean water. Observe the grease removal and calculate the degreasing rate.

[0051] 3. Experimental Results: Degreasing rate = (oil stain formation area - residual area) / oil stain formation area * 100%.

[0052] Table 2. Results of oil removal effect test

[0053] Depend on Figure 1 , Figure 2 , Figure 3 As can be seen, before cleaning, the iron plate was covered with stubborn oil stains and a large amount of black carbon deposits. After cleaning with the high-temperature degreasing stove cleaners used in Examples 1, 2, and 3, the iron plate was basically clean. Figure 4 , Figure 5 , Figure 6 It can be seen that after cleaning with the stove cleaners of Comparative Examples 1, 2, and 3, oil stains still remained on the iron plate.

[0054] As shown in Table 2, the degreasing rates of the high-temperature degreasing stove cleaners in Examples 1, 2, and 3 are 94%, 95%, and 98%, respectively. In contrast, the degreasing rates of the stove cleaners in Comparative Examples 1, 2, and 3 are 60%, 70%, and 73%, respectively.

The corrosion rate is obtained by gravimetric method.

[0057] 3. Experimental results: Corrosion rate = (W1-W2) / W1×100%, and the corrosion test results are shown in Table 3.

[0059] As shown in Table 3, the high-temperature degreasing stove cleaner of Example 3 has a corrosion rate of 0.004% on stainless steel sheets (material 304). In contrast, the stove cleaner of Comparative Example 4 has a corrosion rate of 0.012% on stainless steel sheets (material 304). Therefore, the high-temperature degreasing stove cleaner provided by this invention has an extremely low corrosion rate on stainless steel sheets (material 304), and is essentially non-corrosive.
