the silver ion antibacterial agent comprises polyethyleneimine, silver salt and water.
In the silver ion antibacterial laundry detergent, the mixed nonionic surfactant is a mixture of coconut oil fatty acid diethanolamide, fatty alcohol polyoxyethylene (9) ether and fatty alcohol polyoxyethylene (7) ether. Specifically, the mixed nonionic surfactant comprises 10-30 wt% of coconut oil fatty acid diethanolamide, 30-50 wt% of fatty alcohol polyoxyethylene (9) ether and the balance of fatty alcohol polyoxyethylene (7) ether; more specifically, in the mixed nonionic surfactant, the content of coconut oil fatty acid diethanolamide is 15-25 wt%, the content of fatty alcohol polyoxyethylene (9) ether is 35-45 wt%, and the balance is fatty alcohol polyoxyethylene (7). The content of the mixed type nonionic surfactant is 10-40 wt%, and more specifically, the content of the mixed type nonionic surfactant is 15-35 wt%.
In the silver ion antibacterial laundry detergent, the builder is selected from sodium citrate. The content of the builder is 1 to 5 wt%, more specifically, 1.5 to 4 wt%. The perfume is selected from perfumes well known to those skilled in the art, and the selection thereof is not particularly limited herein; in the present application, the essence is specifically selected from one of lavender essence and rose essence. The content of the essence is 0.1-1%, and specifically, the content of the essence is 0.2-0.8 wt%.
The silver ion antibacterial agent comprises polyethyleneimine, silver salt and water, and the mass ratio of the silver ion antibacterial agent to the water is 5-30: 1: 100-700 parts; in a specific embodiment, the mass ratio of the polyethyleneimine, the silver nitrate and the water is 20:1: 500. The polyethyleneimine is a cationic surfactant and has bactericidal performance, and can form a stable ligand with silver ions as a stabilizer; moreover, the polyethyleneimine serving as a dispersing agent can enable the polyethyleneimine and silver ions to form a stable ligand and be uniformly mixed with other components in the laundry detergent, so that local uneven silver ion concentration is avoided. In the present application, the silver salt may be chosen in particular from silver nitrate or silver acetate. The silver ion antibacterial agent is prepared by the following method: the polyethyleneimine is mixed with water and then silver nitrate is added. The content of the silver ion antibacterial agent is 1-5 wt%, and more specifically, the content of the silver ion antibacterial agent is 3-4 wt%. The silver ion composite antibacterial agent can be stable and not easy to discolor by regulating the proportion of the silver salt to the polyethyleneimine, and simultaneously, the silver ions can be uniformly dispersed in the laundry detergent and are not aggregated.
The preparation method of the silver ion antibacterial laundry detergent specifically comprises the following steps:
A) heating deionized water, and adding a mixed nonionic surfactant to obtain an initial mixture;
B) cooling the initial mixture, and then sequentially adding a builder and essence; finally adding silver ion antibacterial agent.

The performances of the products of the embodiments 1-4 are as follows: the detergency meets the requirements of national industry standard QB/T1224-2012.
The antibacterial performance of the silver ion antibacterial laundry detergent is tested according to QB/T2738-2012, namely an evaluation method for antibacterial and bacteriostatic effects of daily chemical products, wherein the action concentration is 1:100, and the action time is 20 minutes. The results of the experiment are shown in table 1.
Table 1 antibacterial property test effect of silver ion antibacterial laundry detergent
Experiment results show that the bactericidal rate of the silver ion antibacterial laundry detergent in the embodiments 1-4 to staphylococcus aureus and escherichia coli can reach more than 99%; in comparative examples 1-4, polyethyleneimine or silver ions are used alone as an antibacterial agent, and the sterilization rate is lower than that in examples 1-4, which shows that the polyethyleneimine and silver ions have a synergistic antibacterial effect after being combined.
The stability of the silver ion antibacterial laundry detergent is tested according to the stability test method in QB/T1224-2012.
Table 2 table of stability analysis of laundry detergent prepared in examples and comparative examples
| Item | Stability of |
| Example 1 | No precipitation and turbidity |
| Example 2 | No precipitation and turbidity |
| Example 3 | No precipitation and turbidity |
| Example 4 | No precipitation and turbidity |
| Comparative example 1 | No precipitation and turbidity |
| Comparative example 2 | Turbidity of the solution |
| Comparative example 3 | No precipitation and turbidity |
| Comparative example 4 | Turbidity of the solution |
Experimental results show that the silver ion antibacterial laundry detergent in the embodiments 1-4 does not produce precipitates, is not turbid, and has good stability, and the laundry detergent added with polyethyleneimine has strong stability in combination with a comparative example, but the silver ion laundry detergent singly used can generate a turbid phenomenon.
