Description

Technical Field

[0001] The invention belongs to the technical field of deodorization, and particularly relates to a high-efficiency deodorant and a preparation method thereof. Background Art

[0002] Deodorants are products used to remove or mask odors and are widely used in many fields such as household, industrial, personal care and pet care. Deodorants can be divided into many types according to their ingredients, mechanism of action and usage scenarios. The main types of deodorants are classified by mechanism of action: a. Neutralizing deodorant Principle: Convert odor molecules into odorless or low-odor compounds through chemical reactions.

[0003] Application: Suitable for odor treatment in kitchens, toilets, trash cans and other places.

[0004] b. Absorption deodorant Principle: Use porous materials (such as activated carbon) to adsorb odor molecules.

[0005] Application: Suitable for removing odor in closed spaces such as refrigerators, shoe cabinets, and cars.

[0006] c. Decomposition type deodorant Principle: Use biological enzymes or microorganisms to decompose organic substances that produce odor.

[0007] Application: Suitable for treating odors from organic matter such as pet urine and feces.

[0008] d. Masking deodorants Principle: Cover up the odor by adding fragrance substances.

[0009] Application: Suitable for situations where odors need to be quickly covered, such as temporarily dealing with odor problems when visitors come to visit.

[0010] CN 110624388 B discloses a deodorant composition, a deodorant and its application, wherein the deodorant composition contains an alkyl imidazole type ionic liquid, triethanolamine borate, polyethylene oxide, a penetrant, and an antibacterial agent, and the weight ratio of the alkyl imidazole type ionic liquid, triethanolamine borate, polyethylene oxide, a penetrant, and an antibacterial agent is 1: 0.1-4.0: 0.05-0.5: 0.05-0.5: 0.001-0.2. The method for deodorizing malodorous odors comprises contacting an aqueous solution containing the deodorant composition with a malodorous gas. The prepared deodorant composition meets the requirements of green environmental protection and can be used to eliminate odors such as hydrogen sulfide, methyl mercaptan, and methyl sulfide. However, the preparation of ionic liquids is relatively complicated, the cost is high, and the application is difficult. Summary of the invention

[0011] In order to solve the above technical problems, the present invention provides a high-efficiency deodorant, which is composed of the following substances in parts by mass: Polyacrylamide 0.01~0.1 parts 3~10 parts of porous starch Calcium chloride 2-3 parts 1~2 parts of dicationic quaternary ammonium salt 3~5 parts of hydrogen peroxide solution 80~100 parts of deionized water 3~5 parts of honeysuckle extract Stabilizer 0.5~1 part 3~5 parts of organic acid.

[0012] The deodorant prepared by the present invention is used in a spraying manner. As the water of the added porous starch evaporates, the dicationic quaternary ammonium salt and the effective ingredients in the honeysuckle extract are enriched in the pores of the porous starch, thereby prolonging the deodorizing effect of the product. At the same time, the pores of the porous starch can form hydrogen bonds with sulfide, ammonia, etc., and the porous structure has an adsorption effect, and the porous structure itself also has a deodorizing effect.

[0013] Furthermore, the polyacrylamide is cationic polyacrylamide. As a high molecular compound, cationic polyacrylamide can increase the viscosity of water after being dissolved in water, so that the porous starch can be evenly distributed in the solution. If the amount added is too little, its effect cannot be exerted. If the amount added is too large, the viscosity of the solution is too high and it cannot be used. Therefore, the amount added needs to be strictly controlled. At the same time, because it has a variety of active groups, it can be affinity and adsorbed with sulfides, ammonia, etc. to form hydrogen bonds, and has a deodorizing effect.

[0014] Furthermore, the dicationic quaternary ammonium salt is didecyldimethylammonium chloride or didecylmethylammonium chloride. The dicationic quaternary ammonium salt can play a bactericidal role. At the same time, the dicationic quaternary ammonium salt can also form hydrogen bonds with sulfides, ammonia, etc., and has a certain deodorizing effect.

[0015] Furthermore, the concentration of the hydrogen peroxide solution is 20-35wt%, and hydrogen peroxide can have a significant adsorption effect on reducing odors such as hydrogen sulfide, and has a bactericidal function.

[0016] Furthermore, the organic acid is citric acid or tartaric acid. Adding the organic acid can make the solvent acidic, playing the dual role of stabilizing hydrogen peroxide and absorbing ammonia.

[0017] Furthermore, the extraction method of the honeysuckle extract is to soak the honeysuckle in ethanol that is 5 times its mass for 20 hours, and then heat and concentrate until the solvent evaporates 50% to obtain the honeysuckle extract. The honeysuckle extract itself has a deodorizing effect and can also optimize the taste experience of the deodorant with a good effect.

[0018] Furthermore, the stabilizer is hydroxyethylidene diphosphonic acid or aminotrimethylphosphonic acid, and the stabilizer can make the solvent acidic, playing a dual role of stabilizing the decomposition of hydrogen peroxide and adsorbing ammonia.

[0019] Furthermore, the highly effective deodorant is composed of the following substances in parts by mass: Polyacrylamide 0.05 parts 5 parts porous starch Calcium chloride 2 parts 2 parts of dicationic quaternary ammonium salt 3 parts hydrogen peroxide solution 80 parts of deionized water 3 parts honeysuckle extract Stabilizer 0.5 parts 4 parts of organic acid.

[0020] At the same time, the present invention also provides a method for preparing the high-efficiency deodorant, comprising the following steps: S1: Deionized water is added into a stirring kettle, followed by calcium chloride, dicationic quaternary ammonium salt, and honeysuckle extract, and stirring is started to mix evenly; S2: adding an organic acid and a stabilizer to the mixed solution obtained in step S1, and then adding a hydrogen peroxide solution to mix evenly. The stabilizer and the organic acid must be added before adding the hydrogen peroxide, otherwise the hydrogen peroxide will decompose and affect the use effect; S3: adding porous starch to the mixed solution obtained in step S2, stirring quickly and evenly, and then adding polyacrylamide to mix evenly. The porous starch must be added first, and then polyacrylamide is slowly added to gradually increase the viscosity of water to obtain a uniform and stable solution. If the order is reversed, it will be difficult to mix the porous starch evenly in the solution.

[0021] Furthermore, the stirring speed of the rapid stirring in step S3 is greater than 300 rpm. When the porous starch is completely suspended in the solution after rapid stirring, polyacrylamide is added and the solution is packaged into spray packaging bottles for storage.

[0022] The deodorant prepared by the present invention has simple components, low cost, simple preparation method, good deodorizing effect, and also has sterilization and disinfection functions. It can be applied to hospitals, homes, pet places and other scenes, has wide application and good effect. DETAILED DESCRIPTION

[0033] Comparative Example 1 Use deionized water as a deodorizer.

[0034] Comparative Example 2 The porous starch in Example 1 is replaced with starch, and the rest is the same as Example 1 and will not be described in detail.

[0035] Comparative Example 3 The hydrogen peroxide solution component in Example 1 is removed, and the rest is the same as Example 1, which will not be repeated here.

[0036] Comparative Example 4 The hydroxyethylidene diphosphonic acid component in Example 1 was removed, and the rest was the same as Example 1, which will not be described in detail.

[0037] Comparative Example 5 The didecyldimethylammonium chloride component in Example 1 was removed, and the rest was the same as Example 1, which will not be repeated here.

[0038] The deodorizing performance of the deodorants prepared in the above examples and comparative examples was measured. The results are shown in Table 1.

[0039] The specific test method is to prepare a mixed gas with an ammonia concentration of 100 mg / L, a hydrogen sulfide concentration of 100 mg / L, a methyl sulfide concentration of 100 mg / L, and the remaining components being air. 3 Place at 1m 3 In a closed container, 5 ml of the deodorant of the present invention is sprayed. After 48 hours, the content of each component in the mixed gas is measured and the removal rate is calculated. Removal rate = (initial single gas concentration - single gas concentration after deodorization) / initial single gas concentration × 100%. For example, if the initial ammonia concentration is 100 mg / L and the concentration after deodorization is 1 mg / L, the removal rate is 99%.

[0040] Table 1 Measurement results Removal rate Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Ammonia removal rate, % 99.2 98.8 98.7 42.1 89.1 92.1 89.1 93.6 Hydrogen sulfide removal rate, % 99.3 98.8 98.9 10.2 82.1 69.2 88.1 92.4 Methyl sulfide removal rate, % 98.4 97.9 98.1 5.3 79.1 77.5 87.7 92.8 As can be seen from the data in the above table, the removal rates of ammonia, hydrogen sulfide and dimethyl sulfide in Examples 1 to 3 are relatively high and the effects are remarkable. The data of Comparative Example 1 show that water only has a certain removal rate for ammonia, and the removal rates for the other two components are very low. The data of Comparative Example 2 show that porous starch has better technical effects than starch. The data of Comparative Example 3 show that hydrogen peroxide has a more significant removal effect on hydrogen sulfide. The data of Comparative Example 4 show that after removing hydroxyethylated diphosphonic acid, the removal rates of ammonia, hydrogen sulfide and dimethyl sulfide are all reduced. On the one hand, hydroxyethylated diphosphonic acid itself has a certain removal effect, and on the other hand, it may be because, before use, the double oxidation is partially decomposed, resulting in a decrease in the removal rate. The data of Comparative Example 5 show that didecyl dimethyl ammonium chloride has a certain removal rate for ammonia, hydrogen sulfide and dimethyl sulfide.

[0041] The bactericidal performance of the deodorants prepared in the above examples and comparative examples was measured and the results are shown in Table 2.

The Staphylococcus aureus test is tested in accordance with GB4789.10-2010.

[0043] From the data in the above table, it can be seen that Examples 1 to 3 have high sterilization effects on Staphylococcus aureus. The data of Comparative Example 3 shows that hydrogen peroxide has a greater influence on the sterilization effect. The data of Comparative Example 5 shows that didecyl dimethyl ammonium chloride has a certain sterilization effect.
