Description

Technical Field

[0001] The invention belongs to the technical field of chemical cleaning agents, and in particular relates to an antibacterial cleaning agent for a washing machine and a production method thereof. Background Art

[0002] When washing clothes with a washing machine, users often only pay attention to whether the clothes are washed clean, but often ignore whether the washing machine itself is clean. A disease control center once conducted a survey on the dirt in household washing machines. The results showed that the total bacteria count in washing machines exceeded the standard by 81.3%, the total coliform detection rate was 100%, and the mold detection rate exceeded 60.2%. The main reasons why washing machines are prone to mold and bacteria are as follows: ① Environmental problems. Washing machines are generally placed in dark and humid places such as bathrooms, which are not conducive to the loss of residual water. ② Residual water problem. After washing, water will remain in the drainage pump and drainage pipe, forming odor and bacteria. ③ Fine debris problem. Cotton scraps and scale that fall off clothes cannot be completely discharged, but are attached to the inside of the washing machine.

[0003] Various bacteria, especially mold, in the washing machine can cause skin diseases or fungal diseases. Since fungal infections are generally related to immune function, they are highly infectious to the elderly, pregnant women and children with weak resistance. Therefore, washing machines should be regularly maintained and cleaned and disinfected. There are two common ways to clean washing machines: one is to ask professional maintenance workers to dismantle the washing machine tank for cleaning. This cleaning method is suitable for simultaneous maintenance of the washing machine. The other is to use a professional washing machine tank cleaner.

[0004] At present, commonly used washing machine cleaning agents are divided into the following types: one is to use surfactants as active ingredients. The compounded surfactants soak the stains, which can effectively peel off and decompose stubborn dirt; at the same time, it destroys the biofilm, exposing a large number of pathogens to the washing water, achieving the purpose of removing dirt. The second is to use percarbonate as an active ingredient, which destroys the basic molecular structure of pathogenic proteins through oxidation to achieve a strong sterilization effect. The third is to use chlorine-containing factors, benzalkonium chloride, parachloro-metaxylenol and other antibacterial agents as active ingredients, and directly use their strong bactericidal ability to clean the washing machine.

[0005] Chinese patent CN201911199429.7 discloses "a washing machine tank cleaning agent and its preparation method", which is composed of the following components by mass percentage: 10-30% percarbonate, 12-20% biological enzyme preparation, 11-15% chelating agent, 6-10% corrosion inhibitor, 6-10% surfactant, and the balance is water. The washing machine tank cleaning agent provided by the invention has unsatisfactory cleaning and sterilization effects in actual use. Therefore, it is still of great significance and necessity to develop a washing machine cleaning agent with excellent cleaning and sterilization effects. Summary of the invention

[0006] One of the purposes of the present invention is to provide an antibacterial cleaning agent for a washing machine to solve or alleviate the problems existing in the above-mentioned prior art.

[0007] In order to achieve the above-mentioned purpose, a washing machine antibacterial cleaning agent of the present invention adopts the following technical scheme:

[0008] A washing machine antibacterial cleaning agent comprises the following components in parts by weight: 10-35% of percarbonate, 0.1-2% of ethylenediaminetetraacetic acid, 5-25% of sodium peracetate, 0.1-2% of stabilizer, 2-10% of surfactant, 5-10% of corrosion inhibitor, 10-16% of chelating agent, 1-5% of flavor, 1-5% of foam stabilizer, 1-5% of bactericide, 2-10% of gardenia extract, 1-5% of soapberry extract and 1-5% of tea polyphenols.

[0010] Preferably, the surfactant is at least one of lauric acid, sodium lauryl sulfate, sodium dodecylbenzene sulfonate, benzalkonium chloride, betaine, and betaine-type amino acid derivatives.

[0011] Preferably, the corrosion inhibitor is at least one of nitrite, borate and camphor leaf water extract.

[0012] Preferably, the chelating agent is tetrasodium glutamate diacetate and / or aminocarboxylic acid.

[0013] Preferably, the flavor is lemon flavor; the foam stabilizer is at least one of polyacrylamide, dodecyl dimethyl amine oxide, and alkyl alcohol amide; and the bactericidal agent is at least one of benzalkonium chloride, tea tree oil, and aloe vera.

[0014] The second object of the present invention is to provide a method for producing an antibacterial cleaning agent for a washing machine to solve or alleviate the problems existing in the above-mentioned prior art.

[0015] In order to achieve the above-mentioned purpose, the production method of a washing machine antibacterial cleaning agent of the present invention adopts the following technical scheme:

[0016] A production method of an antibacterial cleaning agent for a washing machine comprises the following steps: uniformly stirring percarbonate, sodium peracetate and a stabilizer, adding gardenia extract, soapberry extract and tea polyphenols, continuing to uniformly stir, then adding corrosion inhibitor, chelating agent, essence, foam stabilizer and bactericide, stirring, then adding ethylenediaminetetraacetic acid and a surfactant, stirring; finally, sieving the uniformly mixed material, sampling and testing, standing at room temperature for 2 hours after passing the test, and sealing.

[0017] Preferably, the sieve has a mesh size of 20 to 80.

[0018] The third object of the present invention is to provide a method for producing an antibacterial cleaning agent for a washing machine to solve or alleviate the problems existing in the above-mentioned prior art.

[0019] In order to achieve the above-mentioned purpose, the application of an antibacterial cleaning agent for a washing machine of the present invention adopts the following technical scheme:

[0020] The invention discloses an application of an antibacterial cleaning agent for washing machines in the field of washing machine cleaning.

[0021] Beneficial effects:

[0022] The invention provides a washing machine antibacterial cleaning agent, which comprises percarbonate, ethylenediaminetetraacetic acid, sodium peracetate, stabilizer, surfactant, corrosion inhibitor, chelating agent, essence, foam stabilizer, bactericide, gardenia extract, soapberry extract and tea polyphenol. The washing machine antibacterial cleaning agent has the characteristics of being environmentally friendly, pollution-free, skin-protecting and having strong decontamination ability.

[0023] The present invention adopts percarbonate and sodium peracetate as dual oxidants, which has the characteristic of stronger decontamination ability. Sodium percarbonate (2Na2CO3﹒3H2O2) is easily decomposed into sodium carbonate (Na2CO3) and hydrogen peroxide (H2O2) in water, among which sodium carbonate is easily hydrolyzed to generate hydroxide ions (OH - ) makes the cleaning agent alkaline and reduces the concentration of calcium, magnesium and other ions in the solution, which increases the negative charge in the cleaning agent and enhances the mutual repulsion between the anti-anionic active agent and the dirt, thereby improving the cleaning effect. In addition, sodium carbonate has little side effects on the human body and has a good decontamination effect. It is often used for decontamination and deodorization in daily life. Hydrogen peroxide is a dibasic weak acid and is extremely unstable. Under alkaline conditions, it can combine with hydroxide ions to form perhydroxyl ions (HO2 - ), the perhydroxyl ions can be ionized to produce hydroxide ions and monatomic oxygen (O·), and the active monatomic oxygen can combine with water molecules to generate hydroxyl free radicals. Both monatomic oxygen and hydroxyl free radicals are active oxygen, and they are both highly oxidizing. Among them, monatomic oxygen is extremely unstable and can penetrate deep into the stains, accelerating their decomposition and causing them to peel off from the inner tank of the washing machine. Hydroxyl free radicals (OH·) can enter the bacteria, destroy bacterial proteins, enzymes, etc., and cause bacterial DNA degradation.

[0024] Sodium peracetate is alkaline, and peracetic acid is also a weak acid, which has strong oxidizing properties. The present invention is supplemented with ethylenediaminetetraacetic acid, which helps to promote the oxidizing ability of the oxidant (percarbonate and sodium peracetate).

[0025] The stabilizer is selected from 8-hydroxyquinoline, sodium alginate, cactus mucus, firewood extract, and the stabilizer helps to improve the stability of the cleaning agent. At the same time, the stabilizer can be selected from environmentally friendly and pollution-free plant extracts, such as sodium alginate, cactus mucus, and firewood extract. The surfactant is selected from lauric acid, sodium lauryl sulfate, sodium dodecylbenzene sulfonate, benzalkonium chloride, betaine, and betaine-type amino acid derivatives. The surfactant can be anionic, cationic or amphoteric surfactants, among which the betaine-type amino acid derivatives are two betaine-type amino acid derivatives from Japanese pleurotus eryngii [J]. International Journal of Traditional Chinese Medicine, 1998 (6): 36-36.

[0026] The corrosion inhibitor is selected from nitrite, borate, and water extract of camphor leaves, the chelating agent is selected from tetrasodium glutamate diacetate and / or aminocarboxylic acid, the foam stabilizer is selected from polyacrylamide, dodecyl dimethylamine oxide, and alkyl alcohol amide, and the bactericide is selected from benzalkonium chloride, tea tree oil, and aloe vera.

[0027] The invention also includes essence, gardenia extract, soapberry extract and tea polyphenols, wherein lemon in this formula also has the functions of complexation, sterilization and improvement of product odor, so that it has a lemon fragrance favored by consumers. Gardenia extract can leave a lasting fragrance on clothes, soapberry extract has a cleaning effect; tea polyphenols have the characteristics of radiation protection, antibacterial and antienzyme.

[0028] The raw materials of the cleaning agent of the present invention are mostly selected from plant extracts, supplemented with non-toxic inorganic raw materials, and have natural plant fragrance, rich fragrance, and the fabric still has a comfortable fragrance after washing. The cleaning agent of the present invention has strong oxidation ability and can be quickly decomposed in water. The cleaning agent has a bactericidal effect and can remove bacteria in the washing machine to prevent bacteria from being transmitted to clothes. The waste liquid after washing with the cleaning agent prepared by the present invention is easy to degrade, and the discharge is harmless to the environment, green and environmentally friendly, and is the first choice for people who attach importance to environmental protection, health, and children.

[0072] The above-mentioned embodiments and comparative examples all adopt the above-mentioned method.

[0073] 3. Testing the cleaning agents of the above embodiments and comparative examples:

[0074] (1) Stability determination

[0075] This test uses the accelerated test method to determine the stability of the cleaning agent. Accurately weigh 50.0g of the sample, place it in a test tube, cover it with a stopper, place it on a test tube rack, place it in an electric constant temperature drying oven, store it at 54℃ for 14 days, take it out and cool it, invert it in a beaker, shake it well, and refer to the "Hygiene Requirements for Sodium Percarbonate Disinfectants" (WT / T 6456-2019) (National Health Commission of the People's Republic of China. Hygiene Requirements for Sodium Percarbonate Disinfectants: WS / T 646-2019[S]. Beijing: China Standards Press, 2019), and use the redox titration method to determine the active oxygen content of each washing machine trough cleaning agent and calculate its active oxygen content reduction rate.

[0076] (2) Sterilization rate determination

[0077] Prepare bacterial suspension, identify neutralizing agent and determine sterilization rate according to the test steps 2.1.1.2.3, 2.1.1.5.5 and 2.1.1.7.3 of "Technical Specification for Disinfection (2002 Edition)" (Ministry of Health of the People's Republic of China. Technical Specification for Disinfection [S]. Beijing: China Standards Press, 2002).

[0078] The results are as follows:

After the cleaning agents are placed at 54°C for 14 days using the accelerated test method, the active oxygen reduction rate of the cleaning agents of Examples 1-20 of the present invention is 5.6%. The active oxygen content of Comparative Examples 1-3 is 10.11%. After the cleaning agents are placed at 54°C for 14 days using the accelerated test method, the active oxygen reduction rate of the cleaning agents of Comparative Examples 1-3 is 15.7%. It shows that the cleaning agents of the present invention have high active oxygen content and good stability.

[0080] After testing, the cleaning agents prepared in Examples 1-20 were evaluated by the method of carrier quantitative killing experiment. The sterilization rates of the cleaning agent solution with a concentration of 0.5% (w / v) for 90 minutes against Escherichia coli were 99.9999%, and the sterilization rates of Staphylococcus aureus were 99.9999%; while the sterilization rates of Ratios 1-3 against Escherichia coli were 91.78%, and the sterilization rates of Staphylococcus aureus were 92.34%.

[0081] GB / T 4288-2008 "Electric washing machines for household and similar purposes" stipulates that the residual rinse liquid on the clothes after washing should not be greater than 0.06×10 -2 After testing, the residual alkalinity of the cleaning agent prepared in Examples 1 to 20 on a washing machine was only 0.010×10 -2 mol / L, while the residual alkalinity after washing with the same amount of comparative examples 1-3 in the same washing machine was 0.036×10 -2 mol / L, and the test results show that the residual rate of the cleaning agent of the present invention is significantly lower.

[0082] Compared with comparative examples 1-3, the decontamination performance of the cleaning agents prepared in Examples 1 to 20 is significantly improved. The relative standard powder decontamination value tested according to the method of GB / T13174-2008 "Determination of Detergent Power and Cycle Washing Performance of Detergents for Clothing" can reach 1.3 to 1.7.

[0083] The cleaning agent prepared by the invention has good decontamination and oil removal effects, and can achieve an ideal cleaning effect with a small amount of use. Its detergency relative to standard washing powder is 1.3-1.7, and the national standard detergency is above 1.0, which shows that its detergency has advantages.
