Problems solved by technology

However, people have questioned the safety of this substance, thinking that "the disinfectant with p-chloro-m-xylenol as the main raw material is very easy to use in the process of use due to the insoluble characteristics of its bactericidal components in water." Phenol is formed in the process, and phenol is recognized as a highly carcinogenic substance in the world, which not only has a corrosive effect on the skin and mucous membranes, but also can cause chronic poisoning and environmental pollution.”
[0006] In addition, the phenol-containing or chlorine-containing disinfection and sterilization solutions currently used in the market are all pure organic components, and the sterilization efficiency is very high, but the effectiveness is relatively short, and they are basically disposable. The treated clothes do not have continuous sterilization Antibacterial effect
However, the most widely used antibacterial materials with long-lasting properties on the market, such as inorganic antibacterial agents such as silver and zinc (such as CN200310110093.5, 200410010782.3, 200910156604.4, 200910156605.9, etc.), have low inhibition and killing efficiency to common harmful bacteria. It takes 4-8 hours to play a role, so it cannot meet the needs of quick-acting clothing sterilization

Embodiment 1

[0143] Its preparation steps are as follows:

[0144] A. Preparation of Mesoporous Silicate-loaded Nano-Silver Inorganic Antibacterial Agent Suspension

[0145] (1) Natural zeolite powder (average particle size less than 0.5 μm) produced by Shijiazhuang Huihuangyuan Zeolite Factory was activated with 6N nitric acid for 10 hours at room temperature. The weight ratio of natural zeolite powder to nitric acid was 1, and then washed with water for 3 times , and then neutralized with 10% sodium hydroxide solution by weight to make the pH value reach 6.9, and then centrifuged to obtain active mesoporous silicate;

[0146] (2) Add 30 parts by weight of the active mesoporous silicate and 50 parts by weight of water into the NGJ-3 high-speed mixer produced by Qingdao Hongxiang Petroleum Machinery Manufacturing Co., Ltd., and stir for 1 hour at a rotating speed of 4000r / min to obtain A solution of active mesoporous silicate;

[0147] (3) Drop 20 parts by weight of nano-silver sol into ...

Embodiment 2

[0153] Its preparation steps are as follows:

[0154] A. Preparation of Mesoporous Silicate-loaded Nano-Silver Inorganic Antibacterial Agent Suspension

Abstract

The invention relates to clothing degerming liquid and a preparation method thereof. The method comprises the following steps of: preparing mesoporous silicate nano-silver-loaded antibacterial agent suspension; preparing microemulsion containing an organic antibacterial agent; and adding and mixing an emulsifier, a chelating and anchoring stabilizer, a softener and a thickener. The clothing degerming liquid disclosed by the invention has high using safety, clothing degerming rate of over 99 percent and high stability. Due to the adoption of the clothing degerming liquid, after clothes are washed by water for 20 times, the antibacterial ratio of the clothes is still over 90 percent. The clothing degerming liquid has excellent antibacterial and durable performances, is non-toxic, has no irritation on the skin and has a deodorization effect on fabrics. The clothing degerming liquid disclosed by the invention has simple production process and low equipment investment, is easy for industrial production, is environmental-friendly and has strong market competitiveness.

Description

technical field [0001] The invention belongs to the technical field of sterilization. More specifically, the present invention relates to a laundry sterilizing liquid, and also relates to a preparation method of the laundry sterilizing liquid. Background technique [0002] Washing machine is widely used in people's daily life, has brought convenience and quickness to people's life. Washing machines in daily life often have a musty smell at the bottom after being used for a long time. As people pay more and more attention to hygiene and health, consumers have questioned the possible cross-infection status of washing machines. Experts in the field of disease prevention and control in China conducted a special survey on the sanitation of washing machines in Beijing. The results of the survey showed that the average total number of bacteria in the daily washing water of washing machines reached 13,962 / ml, which is far higher than the national standard of 300 bacteria / square fo...
