Abstract
Description
Technical Field
[0001] The invention relates to the technical field of laundry detergents, in particular to a rapid sterilization and mite-killing laundry detergent and a preparation method thereof. Background Art
[0002] In recent years, with the improvement of people's living standards and the concept of low-carbon and environmental protection, the safety, low carbon and efficacy of laundry products have become hot topics, which are the future development trends of laundry detergents. Traditional washing products mainly use anionic surfactants, whose pH value is greater than 12, which damages human skin. Decontamination performance is the most basic performance of laundry detergents. The synthesis of new surfactants, the compounding of surfactants, and the research of enzyme preparations are all developing towards more efficient decontamination performance. In recent years, there have been many cases of diseases caused by bacterial and viral infections. Consumers are very concerned about washing products with antibacterial and antibacterial functions. Antibacterial detergents can effectively remove bacteria and viruses remaining on clothes, thereby reducing the harm to health. While having the functions of wetting, emulsification, dispersion, volume expansion and cleaning, detergents can protect the user's body and skin safety and prevent bacterial and viral infection and regeneration.
[0003] However, when the laundry detergent is concentrated at 45%-60%, gelation is likely to occur. This is mainly due to the phenomenon that surfactants in the formula, such as AES or fatty alcohol polyoxyethylene ether containing 9 ethylene oxides (AEO9), will occur at high proportions. This brings a lot of inconvenience to the production and use of concentrated laundry detergent. At the same time, after washing, clothes are prone to static electricity, which affects people's experience of use. Ordinary antistatic agents usually cannot work together with active agents and are prone to deactivation. Hydrophilic polymer antistatic agents are a type of organic polymer rich in hydrophilic groups, which can effectively inhibit or eliminate static charges on the surface and inside of polymer materials, and have the advantages of stable, lasting, and environmentally friendly antistatic effects. Summary of the invention
[0004] The object of the present invention is to provide a rapid sterilization and mite-killing laundry detergent and a preparation method thereof, so as to solve the problems existing in the prior art.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a fast sterilizing and mite-killing laundry detergent, wherein the fast sterilizing and mite-killing laundry detergent is prepared by compounding a modified nonionic surfactant and a modified antistatic agent.
[0006] Furthermore, the modified nonionic surfactant is prepared from methyl sorbate, 5-hydroxytryptamine and butyl glycidyl ether.
[0007] Furthermore, the modified antistatic agent is prepared by co-polymerization of dimethyldiallylammonium chloride, vinylbenzenesulfonic acid and 2-methoxyethyl acrylate.
[0008] Furthermore, a method for preparing a rapid bactericidal and mite-killing laundry detergent comprises the following preparation steps:
[0009] (1) Under nitrogen protection, 12 to 18 parts of methyl sorbate and 13 to 21 parts of 5-hydroxytryptamine are mixed evenly, 0.12 to 0.18 parts of potassium hydroxide are added, the temperature is raised to 130 to 140° C., and the mixture is stirred at 120 rpm for 2 to 6 hours. The mixture is concentrated at a vacuum degree of -0.08 MPa and 35° C. for 2 hours to obtain a reaction solution, which is purified to obtain a composite agent;
[0010] (2) Under nitrogen protection, 23-35 parts of the composite agent and 0.68-1.06 parts of potassium hydroxide were mixed evenly, 92-140 parts of butyl glycidyl ether were added, the temperature was raised to 135-145° C., the mixture was stirred at 150 rpm for 4-5 hours, and the mixture was naturally cooled to room temperature to obtain a modified nonionic surfactant;
[0011] (3) 9 to 15 parts of dimethyldiallylammonium chloride, 4 to 8 parts of vinylbenzenesulfonic acid, 5 to 11 parts of 2-methoxyethyl acrylate, and 24 to 58 parts of acetonitrile are mixed uniformly, 0.9 to 1.7 parts of azobisisobutyronitrile acetonitrile solution are added, the temperature is raised to 65 to 75° C., the mixture is stirred at 85 rpm for 2 to 4 hours, the mixture is concentrated at a vacuum degree of -0.07 MPa and 35° C. for 3 hours, the mixture is washed three times with ethanol, and the mixture is dried in a vacuum oven at 45° C. for 12 to 16 hours to obtain a modified antistatic agent;
[0012] (4) Dissolve 1 to 3 parts of sorbitol in 72 to 136 parts of deionized water, add 6 to 10 parts of modified nonionic surfactant and 2 to 4 parts of modified antistatic agent, stir at 45 rpm for 10 to 20 min, add 8 to 14 parts of anionic surfactant, 0.6 to 1.4 parts of thickener, and 0.5 to 1.5 parts of fragrance, stir at 35 rpm for 30 to 40 min, filter with filter cloth, take the liquid, and prepare a rapid bactericidal and mite-killing laundry detergent.
[0013] Furthermore, the purification process of step (1) is as follows: add 20 parts of ethanol to 1 part of the reaction solution, stir for 30 to 40 minutes, filter out the solid, wash it with ethanol three times, and dry it in a vacuum oven at 25 to 35°C for 6 to 10 hours.
[0014] Furthermore, the concentration of azobisisobutyronitrile in the azobisisobutyronitrile acetonitrile solution in step (3) is 5%wt.
[0015] Furthermore, the thickener in step (4) is any one of sodium chloride, polyacrylamide, and coconut diethanolamide.
[0016] Furthermore, the anionic surfactant in step (4) is any one of sodium dodecyl sulfate, sodium lauryl polyether sulfate, and sodium lauryl sulfate.
[0017] Furthermore, the filter cloth in step (4) has a size of 200 mesh.
[0018] Furthermore, the pH value of the rapid bactericidal and mite-killing laundry detergent is 6.0-7.0.
[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:
[0020] The present invention utilizes the steric hindrance effect between multiple branches in the modified nonionic surfactant and mixes it with the modified antistatic agent to reduce the repulsion between the modified antistatic agent and the modified antistatic agent, significantly improve the overall solubilization ability, and achieve the effects of rapid sterilization, strong decontamination and antistatic.
[0021] Firstly, a modified nonionic surfactant is prepared from methyl sorbate, 5-hydroxytryptamine and butyl glycidyl ether; methyl sorbate is subjected to an acylation reaction with 5-hydroxytryptamine to form an amide bond, which promotes hydrogen bonding of water molecules, thereby increasing the cloud point, and further enhancing the hydrolysis stability and hard water resistance. At the same time, methyl sorbate can destroy the cell wall and cell membrane of bacteria, making it impossible for the bacteria to grow and reproduce normally, thereby preliminarily achieving bactericidal performance, and cooperates with the indole structure in hydroxytryptamine to further interfere with the synthesis and metabolism of fungal cell walls, thereby achieving a rapid sterilization effect; then, an alkoxylation addition reaction is carried out with butyl glycidyl ether to form a multi-branched structure, so that the molecular polarity is smoothly transitioned, the oil-water interfacial tension is reduced, and the oil removal ability is preliminarily achieved. On this basis, the length of the hydrophobic chain is extended, and the critical micelle concentration of the surfactant is reduced, thereby improving the ability to reduce the interfacial tension and further enhancing the oil removal effect.
[0022] Secondly, the modified antistatic agent is prepared by co-polymerization of dimethyldiallyl ammonium chloride, vinylbenzenesulfonic acid and 2-methoxyethyl acrylate; a quaternary ammonium salt structure is introduced into the macromolecular chain by using dimethyldiallyl ammonium chloride, so that the antistatic agent can form a conductive layer mainly composed of water ionization under the action of moisture absorption, and can also generate lone pairs of electrons through water molecules or oxygen atoms in the antistatic agent, forming a coordination effect with the empty orbits of nitrogen atoms on the quaternary ammonium salt, thereby achieving a charge dissipation effect and improving the antistatic ability of clothing; the sulfonic acid group introduced by the vinylbenzenesulfonic acid has good detergency and emulsification power, and cooperates with the ethoxy chain of 2-methoxyethyl acrylate, and water molecules attract oxygen atoms in the ethoxy chain under the action of hydrogen bonds, so that the hydrophobic carbon chain -CH2-CH2- is located on the inside, and the ethoxy chain is surrounded by water to form a hydration layer, thereby enhancing the diffusion effect of the antistatic agent and indirectly improving the antistatic effect.
