Composite nano ion bacteriostatic agent

Abstract

The invention discloses a composite nano ion bacteriostatic agent. Micro-nano zinc ions, micro-nano silver ions and micro-nano copper ions are added into a nano ion antibacterial liquid to compound silver ions, copper ions and zinc ions in the nano ion antibacterial liquid, wherein the micro-nano zinc ions are formed by mixing nano-scale zinc ions and micron-scale zinc ions; the micro-nano silverions are formed by mixing nano-scale silver ions and micron-scale silver particles; and the micro-nano copper ions are formed by mixing nano-scale copper ions and micron-scale copper ions. The killingrate of the composite nano ion bacteriostatic agent adopting micro-nano zinc ions, micro-nano silver ions and micro-nano copper ions on escherichia coli, staphylococcus aureus and candida albicans reaches 99% or above, the composite nano ion bacteriostatic agent has the technical effect of continuous sterilization within subsequent 36 hours, and the sterilization rate reaches 99%. The preparationmethod has the beneficial effects that the use problem of nano-silver and nano-copper is effectively avoided, and meanwhile, the antibacterial efficiency of nano-zinc is improved.

Description

technical field [0001] The invention relates to the field of technical antibacterial disinfectants, in particular to a composite nano-ion bacteriostatic agent. Background technique [0002] At present, domestic public places and personal hygiene protection products generally use organic and inorganic disinfectants or natural antibacterial disinfection products to eliminate pathogenic bacteria. However, these disinfection products (such as chlorine-containing and ethanol disinfectant) have a disadvantage. After killing bacteria in an instant, the disinfectant will evaporate in a short time, and the bacteria that spread in the air will reproduce on the surface of the object, so it is not available. Sustained antibacterial function. [0003] In order to solve the above technical problems, those skilled in the art have designed and produced a composite nano-ion antibacterial solution, which has the characteristics of safety, long-term effect, and no pollution, and is more conve...

Problems solved by technology

However, the production cost of nano-silver and nano-copper products is relatively high, and they are easy to oxidize and change color; moreover, silver does not participate in metabolism in the human body, and long-term use will affect health. Although nano-zinc has no problems with the use of nano-silver and nano-copper, And in terms of long-lasting bactericidal and bacteriostatic effects, it is on par with nano-silver and nano-copper antibacterial materials, but the spike-killing effect of nano-zinc is not as good as nano-silver. Experimental results show that it takes at least 5 hours for nano-zinc to kill more than 90% of bacteria, while nano-zinc Silver only takes 600 seconds; therefore, how to repair the short board of nano-zinc and make it a new type of antibacterial product has become an important technical issue to improve the antibacterial effect of composite nano-ion antibacterial liquid
