Description

technical field [0001] The invention relates to the technical field of bacteriostatic materials and preparations, in particular to a bacteriostatic nano-ionic aqueous coating solution, a preparation method of the aqueous coating solution and a bacteriostatic material utilizing the aqueous coating solution. Background technique [0002] With the continuous improvement of people's research and understanding of environmental microorganisms, while using the benefits of microorganisms, they are also very vigilant about their harmfulness as pathogenic bacteria. Every year, the number of deaths caused by bacterial infection in the world is about tens of millions. These infectious diseases include cholera, pneumonia, dysentery, tuberculosis and so on. In addition, microorganisms can also cause decomposition, deterioration and spoilage of various industrial materials, cosmetics, pharmaceuticals, etc., thereby shortening the life of products. Therefore, controlling and eliminating th...

Problems solved by technology

Among them, the defects of nano-silver ion antibacterial materials are as follows: silver ions are precious metals, the cost of use is high, and the core technology requirements are relatively high; the chemical properties of silver ions are relatively active, and they are sensitive to light and heat, especially after being irradiated by ultraviolet rays for a long time. It is black elemental silver, which affects the appearance of white or light-colored products, which greatly limits its application

Most of the antibacterial materials in the internal blending and co-extrusion process are made by internal blending and co-extrusion of nano-ions and basic materials. Usually, the addition ratio of nano-ions is relatively high, and the compatibility between nano-ions and basic materials is poor, and the antibacterial effect of the finished product is not very good. Ideal, and the cost is high; due to the strong activity of nano-ions, some physical properties of the original basic materials will be reduced after internal mixing, resulting in shortened service life
