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
The present invention relates to a kind of inorganic antiseptic and preparation method thereof, relate in particular to a kind of have antibiotic, mildew-resistant, anti-algae multifunctional nano-assembly inorganic antibacterial agent and preparation method thereof.
Background technology
In the modern life, microorganisms such as a large amount of viruses that exist of the environment around people, bacterium, fungi are not only polluting environment, also directly cause the generation and the infection of a lot of diseases, and microorganism can not be ignored hidden danger and the threat that human health causes.According to World Health Organization's statistics in 1996, nineteen ninety-five accounts for 1/3rd of dead sum because of bacterial disease causes 1,700 ten thousand people's death.Occur in the enteropathogenic E O-157 food poisoning of Japan in 1996, once once causing global fear.Spring in 2003, popular " SARS (Severe Acute Respiratory Syndrome) (SARS) " in some areas, the world, it is a kind of new coronavirus, extremely strong contagiosity is arranged, and is the novel infectious disease that people do not understand as yet, because medical circle does not still have the very strong method of effectively preventing and treating of specific aim, cause people's fear once more, this viral disease has directly endangered China's people health and life security in the outburst of China part provinces and cities, is also just caused heavy losses in flourish national economy.Although progress of science and technology has been invented medicine and biologic products such as antibiotic and vaccine, strengthened the safe and sanitary precautionary measures, infectious disease is controlled to some extent, the incidence of disease of present infectious disease still accounts for first of the annual total incidence in the whole world.In recent years international community and China all to cause because of various factors to environment damage and pollution; comprise that pathogenic microorganism has all given great attention to human security and healthy infringement; all by take the legislation and administrative measure; also reducing it by international cooperation to environment damage and pollution; particularly adopt the high and new technology means to improve environmental aspect, the protection human health has formed an emerging pollution-free industry.People spring to action in appealing, do Green Design, and green health material and articles for use are promoted clearer production technology and anti-biotic material, and in today of economic globalization, this also is the essential condition of various countries' sustainable economic development.
Since nineteen ninety-nine, only the application of antibiotic plastic has just related to more than ten industries such as household electrical appliances, cupboard are defended, daily, health care, toy, packing, building materials, communication.China's plastic antimicrobial agent output was 40 tons in 1998,3,000,000 yuan of sales volumes, 3,000,000,000 yuan of the antibacterial product output values; Antibacterial agent output was 150 tons in 1999,1,200 ten thousand yuan of sales volumes, 10,000,000,000 yuan of antibacterial products; 2000, only the antibacterial agent sales volume just reached 200 tons.Estimate will develop into antibacterial agent output thousands of tons of after 2005, antibacterial product reaches several hundred million units.Data shows: if use antibacterial product in Japan is 100, and the America and Europe then is 1, and China only is 0.5～1, and market potential and market capacity are all very huge.In recent years, owing to be subjected to " SARS (Severe Acute Respiratory Syndrome) ", the stimulation of " bird flu " and drive, people's health consciousness will improve greatly, also will increase greatly the demand of health environment-friendly product, and the development of anti-biotic material and goods industry will be much more optimistic than what estimate.
At present, Chang Yong antibacterial agent exists function singleness, application has limitation, properties of product instability, the more high weak point of production cost.
