Description

Technical Field

[0001] This invention relates to the field of furniture cleaning and care technology, specifically to an enzyme-organosilicon synergistic stain-removing furniture cleaner and its preparation method. Background Technology

[0002] Existing furniture cleaners mostly focus on single-function stain removal or use simple combinations of enzymes and surfactants, which suffer from problems such as easy enzyme deactivation and incomplete stain removal. Some antibacterial cleaners rely on chemical disinfectants, which can easily damage solid wood finishes, leather fibers, and other materials, and the residue can easily cause odors. Although some studies have attempted to combine enzymes with organosilicon, these are mostly static mixture systems that have not solved the problems of photocatalytic particle aggregation and synergistic conflicts between enzymes and antibacterial ingredients, and lack adaptation designs for different furniture materials. At the same time, traditional cleaners struggle to balance stain removal efficiency, antibacterial durability, and material protection, failing to meet the comprehensive needs of "gentle cleaning, long-lasting antibacterial effect, and non-damaging material protection" in home and office settings. Therefore, there is an urgent need to develop a new furniture cleaning system that is structurally integrated, functionally synergistic, and highly adaptable to different scenarios. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes an enzyme-organosilicon synergistic stain-removing furniture cleaner and its preparation method. This cleaner achieves synergistic effects between enzymes and photocatalytic particles through the integrated structural design of functionalized microspheres, possessing both highly efficient stain removal and long-lasting antibacterial functions. It also exhibits excellent performance in terms of material compatibility, residue-free properties, and gentleness, meeting the cleaning and care needs of various furniture materials such as solid wood, leather, plastic, and technical fabrics.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] Example 1: This Example 1 describes an enzyme-organic silicon synergistic stain-removing furniture cleaner, prepared from the following raw materials in parts by weight: Functionalized microspheres: 8 parts (porous organosilicon microspheres: 6.5 parts, complex enzyme: 0.52 parts, barium titanate nanoparticles: 0.98 parts), moisturizer: propylene glycol: 2.5 parts, nonionic surfactant: fatty alcohol polyoxyethylene ether: 4 parts, deionized water: 85.5 parts; The preparation steps of the functionalized microspheres are as follows: S1. Add porous organosilicon microspheres and deionized water to the reactor and stir at 100 rpm to disperse them evenly. Then slowly add the complex enzyme (amylase: lipase: protease = 1:1:1), heat to 28℃, adjust the stirring speed to 150 rpm, and keep the temperature constant for 3 hours to allow the complex enzyme to be uniformly loaded on the surface and pores of the microspheres through physical adsorption and chemical bonding of amino functional groups. S2. Keeping the system temperature constant, add barium titanate nanoparticles to the above reaction solution, heat to 32℃, and ultrasonically disperse at 120W power for 1.5 h to make the barium titanate nanoparticles firmly bonded to the surface of the microspheres; after dispersion, centrifuge at 3000 rpm for 10 min, remove the supernatant, and obtain the solid functionalized microsphere product.

[0017] The preparation method of the enzyme-organosilicon synergistic stain-removing furniture cleaner in this embodiment includes the following specific preparation steps: S1.

Add the prepared functionalized microspheres and stir at 135 rpm for 30 min until the system is uniformly dispersed; S3. Adjust the pH value to 7.0 with 0.1 mol / L hydrochloric acid or sodium hydroxide solution, and then filter by vacuum filtration using an aqueous filter membrane with a pore size of 0.45 μm. Filter under a vacuum of 0.07 MPa for 5-10 min to remove a small amount of incompletely dispersed microparticles and any impurities that may be generated in the system. Collect the filtrate, which is the final enzyme-organosilicon synergistic stain-removing furniture cleaner.

[0018] Comparative Example 1: The cleaning agent of Comparative Example 1 was prepared from the following raw materials in parts by weight: 0 parts porous organosilicon microspheres, 0.52 parts composite enzyme, 0.98 parts barium titanate nanoparticles, 2.5 parts humectant: propylene glycol, 4 parts nonionic surfactant: fatty alcohol polyoxyethylene ether, 92 parts deionized water; The preparation method of the cleaning agent in this comparative example includes the following specific steps: S1.

Collect the filtrate as the cleaning agent.

[0019] Comparative Example 2: The cleaning agent of Comparative Example 2 was prepared from the following raw materials in parts by weight: The enzyme-loaded microspheres consist of 7.02 parts (6.5 parts porous organosilicon microspheres, 0.52 parts composite enzyme, and 0 parts barium titanate nanoparticles), 2.5 parts humectant: propylene glycol, 4 parts nonionic surfactant: fatty alcohol polyoxyethylene ether, and 86.48 parts deionized water. The preparation steps of the enzyme-loaded microspheres are as follows: S1. Add porous organosilicon microspheres and deionized water to the reactor and stir at 100 rpm to disperse them evenly. Then slowly add the complex enzyme (amylase: lipase: protease = 1:1:1), heat to 28℃, adjust the stirring speed to 150 rpm, and keep the temperature constant for 3 hours to allow the complex enzyme to be uniformly loaded on the surface and pores of the microspheres through physical adsorption and chemical bonding of amino functional groups. S2. After adsorption is complete, centrifuge at 3000 rpm for 10 min, remove the supernatant, and obtain solid enzyme-loaded microspheres.

[0020] The cleaning agent in this comparative example was prepared using the same method as in Example 1, except that the functionalized microspheres were replaced with enzyme-loaded microspheres.

[0021] Comparative Example 3: The cleaning agent of Comparative Example 3 was prepared from the following raw materials in parts by weight: Functionalized microspheres: 8 parts (porous organosilicon microspheres: 6.5 parts, complex enzyme: 0.52 parts, barium titanate nanoparticles: 0.98 parts), moisturizer: propylene glycol: 2.5 parts, nonionic surfactant: fatty alcohol polyoxyethylene ether: 4 parts, deionized water: 85.5 parts; The preparation steps of the functionalized microspheres are the same as in Example 1, except that the ultrasonic dispersion at 120 W power for 1.5 h is changed to stirring at 150 rpm for 2 h.

[0022] The cleaning agent in this comparative example was prepared using the same method as in Example 1.

[0023] Comparative Example 4: The cleaning agent in Comparative Example 4 was prepared from the following raw materials in parts by weight: Functionalized microspheres: 8 parts (porous organosilicon microspheres: 6.5 parts, complex enzyme: 0.52 parts, barium titanate nanoparticles: 0.98 parts), moisturizer: propylene glycol: 2.5 parts, nonionic surfactant: fatty alcohol polyoxyethylene ether: 4 parts, deionized water: 85.5 parts; The preparation steps of the functionalized microspheres are the same as in Example 1, except that the "porous organosilicon microspheres" are replaced with "porous silica microspheres" of equal mass.

[0024] The cleaning agent in this comparative example was prepared using the same method as in Example 1.

[0025] Performance testing: 1. Detergent cleaning power test The detergency test was conducted according to the GB / T 13174-2023 test method. The specific steps were as follows: White solid wood boards and leather test pieces were selected as test substrates. Three common simulated furniture stains, namely protein-based (egg liquid), oil-based (soybean oil), and mixed (egg liquid and soybean oil mixed in a 1:1 ratio), were applied to the samples and allowed to dry for 1 hour before use. The cleaning agent for each sample was diluted to the same concentration at a ratio of 1:50 according to actual use. An equal amount of diluted cleaning agent was applied to the stain surface with the same force for 15 minutes. The whiteness value of the blank test piece, the whiteness value of the stain test piece before wiping, and the whiteness value of the test piece after wiping were measured using a whiteness meter. The detergency rate was calculated according to the formula "Detergency rate = (Whiteness value after wiping - Whiteness value of stain before wiping) / (Whiteness value of blank test piece - Whiteness value of stain before wiping) × 100%".

[0026] Table 1. Detergent power test data for different samples

[0027] The average detergency of Example 1 reached 95.7%, significantly higher than Comparative Example 1 (without carrier, 75.6%) and Comparative Example 4 (silica carrier, 84.3%), and close to Comparative Example 2 (without barium titanate, 95.3%). This indicates that the organosilicon carrier immobilizes the complex enzyme through physical adsorption and chemical bonding, preventing enzyme molecule inactivation or aggregation, thus allowing it to fully exert its degradation effect on protein and oil stains. Barium titanate, on the other hand, only performs antibacterial functions and has no significant impact on the detergency effect.

[0028] 2. Photocatalytic antibacterial performance test The antibacterial performance test was conducted according to the test method of GB / T 21510-2008. The specific steps were as follows: Staphylococcus aureus and Escherichia coli, common pathogens in furniture, were selected as test strains and prepared into a concentration of 1×10⁻⁶. 6Prepare CFU / mL bacterial suspension; under simulated indoor light (800 lux), temperature 25℃, and humidity 60%, mix the diluted detergent solution of each sample with the above bacterial suspension at a volume ratio of 10:1, and take samples at 0 h and 24 h of light exposure, respectively. Use plate count method to determine the number of viable bacteria in each group. At the same time, set up a blank control group (containing only bacterial suspension and sterile water, without detergent components); calculate the antibacterial rate according to the formula "Antibacterial rate = (Number of viable bacteria in blank group - Number of viable bacteria in experimental group) / Number of viable bacteria in blank group × 100%".

[0029] Table 2. Test data on photocatalytic antibacterial performance of different samples

[0030] Example 1 showed antibacterial rates ≥99.68% against Staphylococcus aureus and Escherichia coli, significantly higher than Comparative Examples 1, 2, and 4, and slightly higher than Comparative Example 3. This indicates that barium titanate is the core antibacterial component, and the loading effect of the organosilicon carrier, combined with the ultrasonic dispersion process, ensures uniform distribution of barium titanate particles (average particle size of only 0.32 μm), allowing for full photocatalytic bactericidal activity under light irradiation. The absence of a carrier or poor carrier compatibility leads to barium titanate aggregation, reducing antibacterial efficiency.

[0031] 3. Stability test of compound enzyme activity The activities of proteases in each sample were determined using the Folin-phenol method, and the activities of amylase and lipase were determined using the DNS method. Different cleaning agent samples were sealed and stored at room temperature (25℃). Samples were taken at 0 days (initial state), 30 days, and 60 days of storage. The activities of the three enzymes in the complex enzyme at each time point were determined according to the corresponding methods described above. The enzyme activity retention rate at different storage times was calculated using the formula "enzyme activity retention rate = (activity after storage / initial activity) × 100%".

[0032] Table 3. Data on the stability of the compound enzyme activity of different samples.

[0033] After 60 days of storage, the activity retention rates of protease, amylase, and lipase in Example 1 were all ≥84.2%, far exceeding those of Comparative Examples 1 and 4, and basically on par with Comparative Example 2. This verifies the excellent biocompatibility of the organosilicon carrier, which can effectively isolate the enzyme molecules from damage caused by the external environment. Without the carrier, the enzymes are easily denatured and inactivated when directly exposed. The pore structure and hydrophilicity / hydrophobicity of the silica carrier are not well-matched, resulting in limited protective effect.

[0034] 4. Barium titanate dispersion stability test The particle size distribution of barium titanate particles in different cleaning agent samples was determined by laser particle size analyzer, and the average particle size was recorded. At the same time, each sample was placed at room temperature and allowed to stand for 72 h to observe whether the system showed stratification or precipitation. The stratification rate was calculated according to the formula "stratification rate = (volume of upper clear liquid / total volume of sample) × 100%" (≤5% is acceptable).

[0035] Table 4. Test data on the dispersion stability of barium titanate for different samples

[0036] In Example 1, the stratification rate after standing for 72 hours was only 2.1% (≤5% acceptable standard), with an average particle size of 0.32 μm, exhibiting the best stability. In Comparative Example 1 (without carrier), the stratification rate reached 18.5%, with a large amount of sediment appearing at the bottom. In Comparative Example 3 (without ultrasonic dispersion), the stratification rate was 9.3%, with an average particle size of 1.57 μm. This indicates that the organosilicon carrier can inhibit barium titanate agglomeration through its loading effect, and the ultrasonic dispersion process further optimizes the dispersion effect; the two work synergistically to ensure the long-term stability of the system.

[0037] 5. Material compatibility test Common furniture materials such as solid wood, artificial leather, polyvinyl chloride (PVC) plastic, and acrylic sheet were selected and cut into standard test pieces of 5cm × 5cm. The initial gloss (solid wood), tensile strength (artificial leather), and hardness (PVC plastic and acrylic sheet) of each blank test piece were measured. Different cleaning agents were evenly applied to the surface of each type of test piece. After standing at room temperature for 24 hours, the surface of the test pieces was thoroughly wiped clean with water and dried. The appearance of the test pieces was observed to see if there was any damage such as discoloration, wrinkling, or cracking. At the same time, the gloss of the solid wood test piece, the tensile strength of the artificial leather test piece, and the hardness of the PVC plastic and acrylic sheet test pieces were re-measured. The gloss retention rate of solid wood (retention rate = gloss after test / initial gloss × 100%) and the tensile strength retention rate of leather (retention rate = tensile strength after test / initial tensile strength × 100%) were calculated. The hardness changes of plastic and acrylic sheets were recorded.

[0038] Table 5. Compatibility Test Data for Different Sample Materials

[0039] Example 1 showed no damage to solid wood, artificial leather, PVC plastic, or acrylic sheets. Solid wood retained 97.8% of its gloss, leather retained 94.5% of its tensile strength, and the hardness change of plastic / acrylic was ≤+0.1H, all meeting the acceptable requirements. In contrast, Comparative Example 4 showed only 89.2% gloss retention for solid wood, 87.2% for leather, and a hardness change of +0.6H for PVC plastic (exceeding the ±0.5H range). The acrylic sheet exhibited severe haziness. This is because the silicone carrier itself is mild and highly compatible with furniture materials, while the silica carrier has a higher surface hardness and stronger hydrophilicity, easily causing physical or chemical damage to the materials.

[0040] 6. Basic physical and chemical properties test The pH value of different cleaning agent concentrates was determined according to GB / T 6368-2008 to ensure that they are in the weakly acidic range of 6.5-7.5 to avoid corroding furniture materials; the initial foam height of each sample was determined according to GB / T 13173-2021, requiring ≤10cm to ensure that the product is easy to rinse and leaves no residue; at the same time, high and low temperature cycling stability tests were carried out, and each sample was cycled three times in sequence under the conditions of -5℃ refrigeration for 24 h, 25℃ room temperature for 24 h, and 45℃ constant temperature for 24 h. After the cycle, the system was observed for any abnormal phenomena such as stratification, discoloration, or precipitation (no abnormalities indicate that it is qualified).

[0041] Table 6. Basic Physicochemical Properties Test Data of Different Samples

[0042] All samples had a pH value in the weakly acidic range of 6.5-7.5, and an initial foam height of ≤8.5 cm (≤10 cm standard), meeting the requirements of "non-corrosive and easy to rinse" for furniture cleaning. In the high and low temperature cycle stability test, Example 1 showed no stratification, no precipitation, and no discoloration, and was in the best condition. Comparative Examples 1 and 3 showed only slight stratification, and Comparative Example 4 showed a very small amount of precipitation. None of these affected actual use, proving that the product still has reliable practicality under extreme storage conditions.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
