specific Embodiment approach 1

[0024] Specific embodiment one: present embodiment is a kind of powerful sterilization and long-lasting antibacterial laundry liquid that adds nano-silver, and this laundry liquid is calculated by mass fraction by 1%~10% oleic acid, 1%~5% palmitic acid, 5%~ 15% fatty alcohol polyoxyethylene ether (3) sodium sulfate, 5% ~ 15% fatty alcohol polyoxyethylene ether (9), 1% ~ 5% Sapinberry extract, 1% ~ 5% potassium hydroxide, 0.05 %~0.1% nano-silver-loaded zeolite antibacterial agent, 0.01%-0.05% chitosan-nano-silver solution, 1%-5% sodium chloride, 0.1%-0.5% Cathone, 0.1%-0.5% spices and the balance of deionized water.

[0025] This embodiment includes the following beneficial effects:

[0026] 1. The laundry detergent described in this embodiment is compounded and used with nanosilver-loaded zeolite antibacterial agent and chitosan-nanosilver solution, so as to achieve the double effect of strong sterilization and long-lasting antibacterial effect;

[0027] The antibacterial an...

specific Embodiment approach 2

[0032] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the strong sterilization and long-lasting antibacterial laundry detergent added with nano-silver is composed of 5% oleic acid, 2% palmitic acid, and 10% fat by mass fraction Alcohol polyoxyethylene ether (3) sodium sulfate, 8% fatty alcohol polyoxyethylene ether (9), 4% Sapinberry extract, 1.2% potassium hydroxide, 0.05% nano silver-loaded zeolite antibacterial agent, 0.01% chitosan It consists of sugar-nanometer silver solution, 2% sodium chloride, 0.2% Cathone, 0.15% spices and the balance of deionized water. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0033]Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the preparation method of described chitosan-nanometer silver solution is: with 0.2mol / L acetic acid solution as solvent, preparation mass fraction is 0.5% Chitosan solution, then take 50mL of chitosan solution with a mass fraction of 0.5%, and add 0.3mL of 0.05mol / L silver nitrate solution to it, stir for 15min at a stirring speed of 800r / min, and then dropwise add 0.1 mL of 0.2mol / L sodium borohydride solution, and finally stirred at a stirring speed of 800r / min for 1h to obtain a chitosan-nanometer silver solution; the viscosity-average molecular weight of the chitosan was 1.33×10 5 , The degree of deacetylation is 90%. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a nano silver added powerful sterilizing and lasting bacteria-resisting laundry detergent and a preparation method therefor, and relates to a laundry detergent and a preparation method therefor. The laundry detergent disclosed by the present invention aims to solve the problem that an existing laundry detergent is poor in sterilizing capability and poor in lasting bacteria-resisting property and has certain toxicity. The laundry detergent consists of a soapberry extraction liquid, a zeolite antibacterial agent carrying nano silver, a chitosan-nano silver solution, kathon and the like. The preparation method comprises the steps of: 1. weighing raw materials; 2. adding deionized water into a reactor, heating and stirring the mixture, and sequentially adding potassium hydroxide, oleic acid and palmitic acid; 3. sequentially adding fatty alcohol polyoxyethylene ether (3) sodium sulfate and the like into the reactor, stirring the mixture and adjusting pH; 4. reducing the temperature, adding the chitosan-nano silver solution, the zeolite antibacterial agent carrying nano silver and stirring the mixture; and 5. sequentially adding sodium chloride, kathon and spices into the reactor and stirring the mixture. The laundry detergent provided by the invention has the effects of powerful sterilization and lasting bacterial resistance, and is environmental-friendly and free of irritation. The present invention is used for preparing the powerful sterilizing and lasting bacteria-resisting laundry detergent.

Description

technical field [0001] The invention relates to a laundry detergent and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of human living standards, people pay more and more attention to health. However, the existing laundry detergents on the market all have unilateral bactericidal or antibacterial effects, poor bactericidal ability, certain toxicity, skin irritation, and pollution. environment, unable to meet consumers' demand for strong sterilization, long-lasting antibacterial, mild and environmentally friendly laundry detergent. [0003] Nano-silver is a simple substance of metallic silver with a particle size of nanometer. The particle size of nano-silver is mostly around 25 nanometers, and it has a strong inhibitory and killing effect on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae, and Chlamydia trachomatis. Harmless to the human body; nano silver-load...
