Novel multifunctional nano-assembly inorganic antibacterial agent and preparation method thereof

Abstract

The invention relates to a novel multifunctional nano assembly inorganic antibacterial agent and a preparation method thereof. The multifunctional nano-assembly inorganic antibacterial agent of the invention is a novel multifunctional nano assembly inorganic antibacterial agent product, with antibiotic, mildewproof and anti-algae effects, which is prepared by taking food-grade silica with a nano aperture (the particle size of 1 to 2 micrometers) or nano silica (the particle size is 20 to 100 nanometers) as a carrier and assembling antibacterial components such as silver, copper and zinc into nano pores. The antibiotic, mildewproof and anti-algae effects of the antibacterial agent product can be freely controlled by controlling the variety and content of the antibacterial components such as silver, copper and zinc. The antibacterial agent of the invention has the prominent characteristics of high-efficiency wide-spectrum antibiosis mildew resistance, algae resistance, long-term effect, safety, non-toxicity, no skin irritation, anti-bacterial sustainability, high temperature resistance, high stability, low comprehensive cost, high cost performance and the like and can be used as a functional additive of sanitary and safe products such as interior wall latex paint, drying water specific coating, swimming pool specific coating, food warehouse specific coating and granary specific coating.

Description

technical field [0001] The invention relates to an inorganic antibacterial agent and a preparation method thereof, in particular to a multifunctional nano-assembled inorganic antibacterial agent with antibacterial, anti-mildew and anti-algae properties and a preparation method thereof. Background technique [0002] In modern life, there are a large number of viruses, bacteria, fungi and other microorganisms in the environment around people, which not only pollute the environment, but also directly lead to the occurrence and infection of many diseases. The hidden dangers and threats caused by microorganisms to human health cannot be ignored. According to the statistics of the World Health Organization in 1996, in 1995, 17 million people died of diseases caused by bacteria, accounting for one-third of the total number of deaths. The pathogenic Escherichia coli O-157 food poisoning incident that occurred in Japan in 1996 once caused panic all over the world. In the spring of 2...

In the spring of 2003, "Atypical Pneumonia (SARS)", which was prevalent in some parts of the world, is a new type of coronavirus, which is highly contagious and a new type of infectious disease that people have not yet understood. The highly effective prevention and control method has once again caused people's panic. The outbreak of this viral infectious disease in some provinces and cities in my country has directly endangered the health and life safety of our people, and also caused serious losses to the booming national economy.

[0004] At present, the commonly used antibacterial agents have shortcomings such as single function, limited application fields, unstable product performance, and high production costs.
