Description

Technical Field

[0001] The invention relates to the technical field of decontamination agent preparation, in particular to a method for preparing a multifunctional effervescent decontamination agent. Background Art

[0002] In recent years, as people's living standards continue to improve and the pace of life continues to accelerate, the number of outings such as business trips, social events and travel has increased. If clothes cannot be washed at any time, it will affect people's quality of life and work. Because the longer the stains stay on the surface of the clothes, the easier it is to form stubborn stains after penetrating into the fibers of the clothes, making them more difficult to remove. If the stains are not cleaned for a long time, they will breed bacteria and affect people's health.

[0003] The laundry products on the market mainly include laundry detergent, washing powder, transparent soap and laundry beads. Since the solubility, mildness and convenience of laundry detergent and transparent soap are not as good as those of laundry detergent or laundry beads, they are gradually being replaced by them. However, the existing laundry detergent has defects such as high logistics costs and single effect. For example, it cannot chelate the bleaching powder in tap water, resulting in some colored clothes getting older and older after washing, and the decontamination effect during the washing process is average. At the same time, people who need to go out have a great demand for removing stains from clothes, and the existing decontamination agents are not easy to carry. To this end, we proposed a method for preparing a multifunctional effervescent decontamination agent to solve the above problems. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a method for preparing a multifunctional effervescent detergent to solve the problems raised in the above background technology.

[0005] The present invention provides the following technical solution: a method for preparing a multifunctional effervescent decontaminant, comprising the following steps:

[0006] S1. Weigh 5-50 g of soda ash, 4-90 g of citric acid, 5-70 g of solid surfactant, 1-5 g of adipic acid dihydrazide, 1-2 g of powdered water-soluble fragrance, 0.01-0.1 g of disperse red dye (Braun Textile RED 2BLR120%) and 0.01-0.03 g of antibacterial agent in order by weight, and put them into a double-helix conical mixer for mixing and stirring;

[0007] S2, adding the bleaching chelating agent to the double-helix conical mixer in step S1 and mixing evenly;

[0008] S3, drying the mixed material prepared in step S2 at 70-80° C. hot air for 45 minutes to obtain the desired decontamination material;

[0009] S4. The decontamination material prepared in step S3 is prepared into an effervescent decontamination and fragrance-retaining decontamination agent having antibacterial, long-lasting fragrance and excellent decontamination ability through a sheet granulator.

[0010] To further optimize the technical solution, the soda ash is a carbonate, including any one of NaHCO3, Na2CO3, MgCO3 and CaCO3, and also includes other food-grade solid carbonates.

[0011] To further optimize the technical solution, the solid acid includes any one of citric acid, tartaric acid, malic acid, gluconic acid, oxalic acid or fumaric acid, and also includes other food-grade solid acids.

[0012] The technical solution is further optimized, in step S1: the double-helix conical mixer controls the rotation speed to 500-600 rpm, stirs evenly, and maintains the temperature below 50°C.

[0013] To further optimize the technical solution, the solid surfactant in step S1 is a water-soluble powdered surfactant, and the powdered surfactant includes a nonionic powdered surfactant, an anionic powdered surfactant, a cationic powdered surfactant or a zwitterionic powdered surfactant.

[0014] To further optimize the technical solution, the solid surfactant is any one of powdered linear alkylbenzene sodium sulfonate, sulfobetaine or anhydrous sodium silicate, and the solid surfactant is used to enhance activity to reduce the resistance to hard water generated internally.

[0015] To further optimize the technical solution, the bleaching chelating agent in step S2 is various functional chemicals with chelating chlorine free radicals, and is selected as hydrazide chelating chlorine free radical chemicals.

[0016] Further optimizing the technical solution, the antibacterial agent in step S1 is any one of polyhexamethylene monoguanidine, polyhexamethylene biguanide and pyrethroid antibacterial agent;

[0017] The packaging design of the effervescent decontamination and fragrance-retaining decontamination agent prepared in step S4 is sheet packaging.

[0018] To further optimize the technical solution, the chemical equations of the soda ash and the solid acid in the reaction process in step S1 are as follows:

[0019] H + +CO3 2- →H2O+CO2↑.

[0020] Further optimizing the technical solution, the chelating agent in step S2 is used to enhance the surface tension and dissolution rate between the components in the solution;

[0021] The powdered water-soluble fragrance and adipic acid dihydrazide in step S1 are auxiliary agents;

[0022] The solid acid in step S1 is a neutralizing agent.

[0023] Compared with the prior art, the present invention provides a method for preparing a multifunctional effervescent decontamination agent, which has the following beneficial effects:

[0024] 1. The preparation method of the multifunctional effervescent detergent utilizes solid powder granulation technology and the principle that carbonate reacts with acid to produce abundant CO2 foam. Solid fragrance, solid surfactant, bleaching chelating agent, solid dye and solid antibacterial agent are mixed in the above-mentioned base material, and the base material is granulated into a detergent with an effervescent tablet effect by a granulator. Solid carbonate and solid acid are used as base materials, and abundant CO2 foaming can be generated when encountering a water-based solution. Solid fragrance is mixed in the above-mentioned base material. The product prepared by the present invention can be made into a variety of products such as laundry effervescent, washing machine effervescent, water cup degreasing, decontamination and stain removal effervescent and pesticide removal effervescent.

[0025] 2. The preparation method of the multifunctional effervescent decontaminant. The effervescent decontaminant prepared by the present invention is easy to control the dosage and is designed to be packaged in sheet form. One sheet corresponds to a certain weight of clothing. When in use, the amount of clothing can be added according to the amount of clothing. It is easy to carry and convenient to transport, and there is no leakage problem. It is more convenient to store and has a fast dissolution speed. Through disintegration, the antibacterial, fragrance, and cleaning ingredients can be quickly dissolved in water. Due to the rich CO2 bubbles generated, the above ingredients can be more evenly dispersed in the water, and the effect is better. A higher purity high-efficiency decontaminant powder can be used to achieve a high-efficiency decontamination and deodorization effect. More functions can be adjusted in the preparation material, such as antistatic, moisture absorption and perspiration or softening functions. The developed products are not limited to antibacterial, lasting fragrance and cleaning functions. BRIEF DESCRIPTION OF THE DRAWINGS
