preparation example Construction

[0034] The preparation method of the inorganic composite material is a common technical means in the field without special limitations; for example, according to the solid-liquid ratio of 1:10, sepiolite is added to the mixed solution of silver nitrate and cerium nitrate, and neutralized at 60°C. Stir for 3.5 hours under the conditions, centrifuge, collect the solid product, wash with distilled water three times, and dry to obtain an inorganic composite material.

[0035]Except for inorganic oxides such as titanium dioxide and zinc oxide, most inorganic antibacterial ingredients need to rely on porous materials to exert their bactericidal effect. The present invention finds through exploration that when clay minerals are selected as the antibacterial component carrier, the sterilizing effect of the antibacterial composition is significantly improved; the reason may be that the inorganic composite material formed after cation exchange between clay minerals and antibacterial comp...

Abstract

The invention relates to the technical field of antibiosis and antivirus, in particular to a multifunctional persistent antibacterial composition and a preparation method thereof. The multifunctional persistent antibacterial composition is prepared from the following raw materials in parts by weight: 20 to 45 parts of antibacterial agent, 1 to 10 parts of plant extract, 0.01 to 1 part of coupling agent, 1 to 5 parts of polysaccharide, 1 to 6 parts of surfactant and 40 to 70 parts of water. The antibacterial composition provided by the invention has the following advantages: (1) the antibacterial composition can perform broad-spectrum sterilization, can effectively kill viruses at the same time, especially has a remarkable effect on new coronavirus, and has important significance on maintaining safety and sanitation of daily public places; (2) the antibacterial composition is excellent in performance and strong in instantaneity when acting on microorganisms, can play a role for a long time, and can be stably stored without discoloring under the change of cold and hot conditions; and (3) the antibacterial composition is environment-friendly in raw material, non-toxic and harmless, simple and convenient in process, capable of being widely applied to the fields of textiles, coatings, plastics and the like, and wide in application prospect.

Description

technical field [0001] The invention relates to the field of antibacterial and antiviral technologies, in particular to a multifunctional and persistent antibacterial composition and a preparation method thereof. Background technique [0002] Various microorganisms are distributed in daily life, and there is a huge potential risk to human life and health. Antimicrobial agents are a class of chemical substances that can significantly reduce the level of microorganisms (including bacteria, fungi, yeast, algae, and viruses) within a specific time scale. Existing antibacterial agents can be divided into inorganic antibacterial agents, organic antibacterial agents and natural antibacterial agents according to different components. Organic antibacterial agents once accounted for more than 80% of the market, and have the characteristics of immediate effect. However, organic antibacterial agents are quite different from different strains, and are prone to drug resistance, volatile ...
