Inorganic nano composite antimicrobial agent and preparation process thereof

Abstract

The invention discloses an inorganic nano composite antimicrobial agent, which is a solution composed of the following components: nano zinc oxide, nano silicon dioxide, nano chitin, polyvinylpyrrolidone, sodium silicate, nano calcium oxide and the balance of solvent. The preparation process comprises the steps of: pre-dissolving zinc oxide, silicon dioxide and chitin, adding a solvent, carrying out repeated extraction, precipitation and filtration to obtain a hyper-concentrated nano solution, adding to the solvent according to a ratio, and stirring. The inorganic nano composite antimicrobial agent has the maximal advantages that long-acting, strong-effect, nontoxic and harmless production is realized and the characteristics, odor, colors and the like of the original product are not changed; the mass production of life antibacterial requisites is realized; and the inorganic nano composite antimicrobial agent is beneficial to human, reduces bacterial injury to human, and indirectly reduces the antibiotic abuse of human. The preparation process provided by the invention is simple, is easy for industrialized mass production, and is low in cost.

Description

technical field [0001] The invention relates to an antibacterial material, especially an antibacterial solution that can be coated or added to other materials. Background technique [0002] In recent years, new types of viruses or bacteria have continuously impacted people's health, such as the SARS outbreak in 2003 and the bird flu in the past two years. It is widely used in people's life, such as disposable sanitary antibacterial products, antibacterial daily chemical products, medical equipment, antibacterial cosmetics, antibacterial building materials, coatings, textiles, plastic products, food, agricultural, fishery and animal husbandry production improvement, leather products , furniture, sanitation equipment, automobile interior decoration, cooling tower sterilization, environmental sanitation, etc., the use of antibacterial materials for sterilization and antibacterial treatment has a significant and broad prospect. [0003] The most common antibacterial materials o...

AI Technical Summary

Problems solved by technology

[0004] Nano-silver: Silver ions are very active and easy to agglomerate. It is not easy to prepare. When nano-silver touches sweat or tap water, it will produce white precipitate of silver chloride. bacteria

[0005] Titanium dioxide photocatalyst: It needs to be irradiated with ultraviolet light to generate potential sterilization, and it cannot be sterilized around the clock

[0008] Overall, the main problems of the above-mentioned antibacterial materials are that they are inconvenient to use, short-acting, and difficult to achieve long-lasting antibacterial effects.
