Description

Technical Field

[0001] This invention belongs to the field of floor cleaner technology, specifically relating to a low-foaming antibacterial floor cleaner suitable for mopping machines and its preparation method. Background Technology

[0002] With the improvement of residents' living standards and the popularization of household cleaning appliances, floor cleaners have gradually expanded from the traditional scenario of manual mopping to the scenario of automated cleaning equipment such as floor mops, floor scrubbers, and sweeper-mop combos. Traditional floor cleaners are usually mainly used for daily manual mopping. They are diluted in a certain proportion and then used to wipe the floor surface with a cloth, mop, or other cleaning tools. Their formulation design mainly focuses on stain removal ability, fragrance, feel, and stability during normal storage.

[0003] However, when ordinary floor cleaners are directly applied to cleaning equipment such as mops, new usage problems can easily emerge. First, some floor cleaners contain surfactant systems with strong foaming properties. During the high-speed operation of the mop's water tank, pump lines, nozzles, and brushes, excessive foam not only affects the normal delivery of the cleaning solution but may also cause abnormal water tank level detection, false alarms in the wastewater tank, or reduced cleaning efficiency. Second, mops typically include components such as a water tank, piping, pump, nozzles, metal connectors, and brushes. If the alkaline additives, surfactants, or other functional additives in the cleaning solution are improperly formulated, long-term use may cause corrosion, aging, or damage to these components. Third, repeated use in humid environments can easily breed bacteria, mold, and other microorganisms in the mop's brushes, water tank, and piping, leading to unpleasant odors over time and negatively impacting the user experience.

[0004] While some existing floor cleaners can meet the cleaning needs of ordinary floor surfaces, they often do not adequately address the comprehensive requirements of low-foaming operation, corrosion resistance, and antibacterial and deodorizing properties for robotic mops. Some low-foaming cleaners reduce foam by lowering the surfactant content or adding large amounts of defoamers, but these methods may lead to decreased detergency or reduced system stability, resulting in problems such as turbidity and stratification during high-temperature storage, low-temperature placement, or long-term storage. Furthermore, while some antibacterial cleaners can improve antibacterial effects, insufficient compatibility between the antibacterial components and the surfactant system may affect the cleaner's stability, low-foaming properties, or equipment compatibility. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a low-foaming antibacterial floor cleaner suitable for mopping machines and its preparation method, which combines good cleaning power, low-foaming performance, antibacterial performance, anti-corrosion performance, and storage stability.

[0006] The technical solution provided by this invention is as follows: On the one hand, a low-foaming antibacterial floor cleaner suitable for mopping machines comprises the following components by weight percentage: Disodium ethylenediaminetetraacetate 0.1%–0.3%, alkyl glycoside nonionic surfactant 2.0%–3.0%, low-foaming nonionic surfactant 1.5%–2.0%, triethanolamine 0.3%–0.7%, corrosion inhibitor 0.05%–0.2%, defoamer 0.1%–0.3%, amine antibacterial agent 0.15%–0.35%, cationic surfactant 0.3%–0.7%, preservative 0.03%–0.08%, fragrance 0.1%–0.3%, balance deionized water; The compound surfactant system consists of alkyl glycoside nonionic surfactants, low-foaming nonionic surfactants, and cationic surfactants. This compound surfactant system, combined with defoamers and amine antibacterial agents, forms a low-foaming antibacterial floor cleaner with low-foaming, antibacterial, and stain-removing properties.

[0007] In some embodiments, the alkyl glycoside nonionic surfactant is AG6206, the low-foaming nonionic surfactant is Ethylan 1005, and the cationic surfactant is Arquad 2C-75.

[0008] In some embodiments, the amine antibacterial agent is Triameen Y12D, the corrosion inhibitor is Crodacor BE, the defoamer is defoamer 638, and the preservative is Kathon CM10.

[0009] In some embodiments, the product comprises, by weight percentage, the following components: 0.2% disodium ethylenediaminetetraacetate, 2.0%–3.0% alkyl glycoside nonionic surfactant, 1.5%–2.0% low-foaming nonionic surfactant, 0.5% triethanolamine, 0.1% corrosion inhibitor, 0.2% defoamer, 0.25% amine antibacterial agent, 0.5% cationic surfactant, 0.05% preservative, 0.2% fragrance, with the balance being deionized water.

[0010] In some embodiments, the mass ratio of alkyl glycoside nonionic surfactant to low-foaming nonionic surfactant is 1:1 to 2:1.

[0011] In some embodiments, the total mass percentage of alkyl glycoside nonionic surfactant, low-foaming nonionic surfactant, and cationic surfactant is 4.0% to 5.5%.

[0012] In some implementations, the low-foaming antibacterial floor cleaner is diluted 1:100 and used for cleaning the water tank of a mop or for routine floor cleaning.

[0013] On the other hand, a method for preparing the above-mentioned low-foaming antibacterial floor cleaner suitable for mopping machines includes the following steps: S1. Add deionized water to the mixing tank, add disodium ethylenediaminetetraacetate under low-speed stirring, then add the premixture of alkyl glycoside nonionic surfactant and amine antibacterial agent, and add low-foaming nonionic surfactant, and stir until dissolved. S2. Add triethanolamine and corrosion inhibitor to the mixing pot and stir until dissolved; S3. Add the cationic surfactant to the mixing tank and stir until dissolved; S4. Add the defoamer to the mixing bowl after pre-diluting it with deionized water, and stir until it is evenly dispersed. S5. Add preservatives and fragrances to the mixing pot and stir well to obtain a low-foaming antibacterial floor cleaner.

[0014] In some embodiments, in step S1, after adding the low-foaming nonionic surfactant, the mixture is stirred at 50 rpm to 80 rpm for 20 min to 40 min; in step S4, the defoamer is pre-diluted with deionized water at a mass ratio of 1:1 before being added.

[0015] In summary, the beneficial effects of this invention are: (1) The present invention uses alkyl glycoside nonionic surfactants and low foaming nonionic surfactants to ensure good wetting, dispersion and removal of dirt on the floor surface, while reducing the amount of foam generated in the system during dilution, shaking, pumping and mopping machine operation, making the cleaning agent more suitable for use in mopping machines, floor scrubbers or sweeping and mopping machines, and reducing the impact of foam on the water tank, pipeline, nozzle and floor brush operation stability.

[0016] (2) The present invention combines cationic surfactants with amine antibacterial agents to improve antibacterial performance while cleaning the floor surface, reducing the risk of microorganisms growing and odors being generated in the water tank, pipes and cleaning brush of the mop in a humid environment, thereby improving the hygiene status and user experience of the cleaning equipment after long-term use.

[0017] (3) The present invention adds corrosion inhibitors to the formulation system and controls the dosage range of triethanolamine, corrosion inhibitors, surfactants and defoamers, so that the cleaning agent can reduce the risk of corrosion to the metal parts, pipeline components, nozzle components and other contact parts of the mop while meeting the cleaning and antibacterial requirements, which is conducive to improving the safety and service life of the equipment.

[0018] (4) By controlling the compounding ratio of components such as AG6206, Ethylan 1005, Arquad 2C-75, Triameen Y12D, Crodacor BE and defoamer 638, and by adopting the preparation sequence of first dissolving the chelating agent, then adding the premix of nonionic surfactant and antibacterial agent, followed by adding the corrosion inhibitor and cationic surfactant, and finally adding the pre-diluted defoamer, the present invention is beneficial to improving the compatibility and dispersion uniformity of each component in the aqueous system, so that the resulting cleaning agent has good stability under both low temperature and high temperature storage conditions and is not prone to stratification.

[0019] (5) The cleaning agent obtained by the present invention can simultaneously meet the dual needs of daily cleaning of ordinary floors and cleaning of floor cleaning machine, avoiding users from purchasing manual floor cleaning agent and equipment-specific cleaning agent separately, and has good ease of use and promotion and application value. Detailed Implementation

[0020] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. The following embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0021] This invention provides a low-foaming antibacterial floor cleaner suitable for mopping machines, comprising disodium ethylenediaminetetraacetate, alkyl glycoside nonionic surfactant, low-foaming nonionic surfactant, triethanolamine, corrosion inhibitor, defoamer, amine antibacterial agent, cationic surfactant, preservative, fragrance, and deionized water. By weight percentage, the low-foaming antibacterial floor cleaner comprises 0.1%–0.3% disodium ethylenediaminetetraacetate, 2.0%–3.0% alkyl glycoside nonionic surfactant, 1.5%–2.0% low-foaming nonionic surfactant, 0.3%–0.7% triethanolamine, 0.05%–0.2% corrosion inhibitor, 0.1%–0.3% defoamer, 0.15%–0.35% amine antibacterial agent, 0.3%–0.7% cationic surfactant, 0.03%–0.08% preservative, 0.1%–0.3% fragrance, and the balance being deionized water.

[0022] Disodium EDTA acts as a chelating agent, complexing calcium and magnesium ions in water to reduce the impact of water hardness on cleaning effectiveness and system stability. Alkyl glycoside nonionic surfactants and low-foaming nonionic surfactants together constitute a low-foaming nonionic surfactant system, enhancing the wetting, penetration, dispersion, and removal of dirt from floor surfaces. Cationic surfactants and amine antibacterial agents work together to improve the antibacterial properties of the floor cleaner, reducing the risk of microbial growth and odor development in the mop's water tank, piping, and cleaning brush after prolonged use. Corrosion inhibitors reduce the risk of corrosion to the mop's water tank, piping, nozzles, pump body, and metal connectors. Defoamers inhibit foam generation during dilution, shaking, pumping, and mop operation, making it suitable for low-foaming applications such as mops. Preservatives improve product storage stability, and fragrances enhance the product's odor.

[0023] In a preferred embodiment, the alkyl glycoside nonionic surfactant is AG6206, the low-foaming nonionic surfactant is Ethylan 1005, the cationic surfactant is Arquad 2C-75, the amine antibacterial agent is Triameen Y12D, the corrosion inhibitor is Crodacor BE, the defoamer is defoamer 638, and the corrosion inhibitor is Kathon CM10. By forming a compound surfactant system with AG6206, Ethylan 1005, and Arquad 2C-75, and in conjunction with Triameen Y12D, Crodacor BE, and defoamer 638, the resulting floor cleaner, even at a 1:100 dilution, retains low-foaming, stain-removing, antibacterial, non-corrosive, and storage-stable properties, making it suitable for both daily mopping and adding water to a mop machine's water tank.

[0024] In this embodiment, AG6206 is an alkyl glycoside surfactant produced by Nouryon (formerly AkzoNobel); Ethylan 1005 is a high-performance nonionic surfactant produced by Nouryon (formerly AkzoNobel); Arquad 2C-75 is a cationic surfactant produced by Nouryon (formerly AkzoNobel Specialty Chemicals); Triameen Y12D is a high-performance, broad-spectrum bactericide and preservative launched by Nouryon (formerly AkzoNobel Functional Chemicals); Crodacor BE is an organoboron ester corrosion inhibitor from Croda; and defoamer 638 and Kathon CM10 are all commercially available products. Under the premise of meeting the same active ingredients, the same functional uses and compatibility, similar products from other manufacturers can also be used.

[0025] The low-foaming antibacterial floor cleaner of the present invention can be prepared according to the following method: First, add some deionized water to the mixing tank, turn on low-speed stirring, add disodium EDTA to disperse and dissolve the disodium EDTA; then add the premix of alkyl glycoside nonionic surfactant and amine antibacterial agent, and then add low-foaming nonionic surfactant. Stir at 50 rpm to 80 rpm for 20 min to 40 min, preferably at about 60 rpm for about 30 min, until the system is uniformly dissolved.

[0026] The second step is to add triethanolamine and corrosion inhibitor to the mixing tank and continue stirring to ensure that the triethanolamine and corrosion inhibitor are fully dissolved and dispersed in the system.

[0027] The third step is to add the cationic surfactant to the mixing tank and continue stirring until the system is homogeneous.

[0028] The fourth step involves pre-diluting the defoamer with deionized water and adding it to a mixing tank, stirring until evenly dispersed. Preferably, the defoamer and deionized water are pre-diluted at a mass ratio of 1:1 before addition. Pre-diluting the defoamer before addition helps it to disperse evenly in the aqueous system, preventing localized aggregation that could affect product appearance, storage stability, and defoaming effect.

[0029] Fifth step: Add preservatives and fragrances to the mixing pot, add the remaining deionized water, and continue to stir until well mixed to obtain a low-foaming antibacterial floor cleaner suitable for mopping machines.

[0052] This comparative example illustrates the effect of defoamer 638 on the foam suppression performance of the detergent at a 1:100 dilution.

[0053] Performance testing: The floor cleaners obtained in Examples 1-5 and Comparative Examples 1-6 were tested for stability, detergency, antibacterial rate, corrosiveness and foaming properties.

[0054] The low-temperature stability test method is as follows: place the sample in a -5℃ environment for 24 hours, then restore it to room temperature, and observe whether the sample separates into layers.

[0055] The high-temperature stability test method is as follows: place the sample in a 40℃ environment for 24 hours, then restore it to room temperature, and observe whether the sample separates into layers.

[0056] The foam performance test method is as follows: Prepare a diluted solution of floor cleaner at a ratio of 1:100, take 60mL of the diluted solution and put it into a 100mL graduated cylinder, shake it up and down 5 times by hand, let it stand for 5 seconds and then observe the foam height.

[0057] The corrosion test method is as follows: the test sample is brought into contact with the commonly used metal parts, pipe parts or nozzle parts of the mopping machine, and after a predetermined time, it is observed whether corrosion, discoloration, spots or surface damage occur.

[0058] The test results are shown in Table 1: Example 1 No layering No layering 97.1 99.9 Non-corrosive 0 Example 2 No layering No layering 97.8 99.9 Non-corrosive 0 Example 3 No layering No layering 98.3 99.9 Non-corrosive 0 Example 4 No layering No layering 96.0 99.9 Non-corrosive 0 Example 5 No layering No layering 99.5 99.9 Non-corrosive 0 Comparative Example 1 No layering No layering 88.6 99.8 Non-corrosive 0 Comparative Example 2 No layering Layering 91.3 99.8 Non-corrosive 10 Comparative Example 3 No layering No layering 94.8 95.6 Non-corrosive 0 Comparative Example 4 No layering No layering 96.5 88.4 Non-corrosive 0 Comparative Example 5 No layering No layering 96.8 99.9 Slight corrosion 0 Comparative Example 6 No layering No layering 96.9 99.9 Non-corrosive 18 Table 1 The results in the table show that the floor cleaners obtained in Examples 1-5 exhibited good performance in terms of low-temperature stability, high-temperature stability, detergency, antibacterial rate, corrosivity, and foaming properties. Specifically, Examples 1-5 did not separate after being placed at -5℃ for 24 hours and then restored to room temperature, nor after being placed at 40℃ for 24 hours and then restored to room temperature; the detergency ranged from 96.0% to 99.5%; the antibacterial rate reached 99.9%; the corrosivity test results showed no corrosion; and the foaming performance test after dilution at 1:100 showed a foam height of 0 mm in all cases. These results demonstrate that the floor cleaners obtained in this invention can maintain good cleaning ability, antibacterial ability, non-corrosiveness, and storage stability even under low-foaming conditions.

[0059] Comparative Example 1 did not include AG6206, and the remaining components were basically the same as in Example 1. The test results showed that the detergency of Comparative Example 1 decreased to 88.6%, which was significantly lower than 97.1% in Example 1, indicating that AG6206 is beneficial to improving the system's ability to wet, disperse, and remove floor dirt.

[0060] Comparative Example 2 did not include Ethylan 1005, and the remaining components were basically the same as in Example 1. Test results showed that the detergency of Comparative Example 2 decreased to 91.3%, the foam height increased to 10 mm after dilution at 1:100, and stratification occurred after a stability test at 40°C. This indicates that Ethylan 1005 can be compounded with AG6206, reducing foam while maintaining detergency, and improving system compatibility and high-temperature stability.

[0061] Comparative Example 3 did not include Arquad 2C-75, and the remaining components were basically the same as in Example 1. Test results showed that the antibacterial rate of Comparative Example 3 decreased to 95.6%, and the detergency decreased to 94.8%. This indicates that Arquad 2C-75 not only helps improve antibacterial performance but also forms a compound surfactant system suitable for floor cleaning with nonionic surfactants, thereby improving the overall cleaning effect.

[0062] Comparative Example 4 did not include Triameen Y12D, and the remaining components were basically the same as in Example 1. The test results showed that the antibacterial rate of Comparative Example 4 decreased to 88.4%, which was significantly lower than the 99.9% of Example 1. This indicates that Triameen Y12D is an important component for achieving a high antibacterial rate and can reduce the risk of microbial growth and odor generation in the floor brush, water tank, or pipes of the mop.

[0063] Comparative Example 5 did not contain Crodacor BE, and the remaining components were essentially the same as in Example 1. Test results showed that Comparative Example 5 exhibited slight corrosion in the corrosion test, indicating that Crodacor BE can reduce the risk of corrosion of the cleaning agent on the metal parts, piping components, or nozzle components of the mop.

[0064] Comparative Example 6 did not contain defoamer 638, and the remaining components were basically the same as in Example 1. The test results showed that the foam height of Comparative Example 6 after dilution at a ratio of 1:100 increased to 18 mm, which was significantly higher than 0 mm in Example 1, indicating that defoamer 638 could effectively inhibit foam generation of the cleaning agent during dilution, shaking, pumping, and operation of the mopping machine.

[0065] As can be seen from the above embodiments and comparative examples, the present invention does not simply combine conventional cleaning agent components arbitrarily, but rather uses a compounding of AG6206, Ethylan 1005, Arquad 2C-75, Triameen Y12D, Crodacor BE and defoamer 638, and controls each component within a suitable ratio range, so that the resulting floor cleaner, when used at a 1:100 dilution, possesses low-foaming, stain-removing, antibacterial, anti-corrosion, and storage-stable properties, meeting the dual needs of daily floor cleaning and mopping machine use.

[0066] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
