Abstract

The invention discloses a negative ion solution with an ultra-strong antibacterial effect and a preparation method thereof, and relates to the technical field of negative ion antibacterial solutions, and the preparation method of the negative ion solution comprises the following steps: carrying out ball milling on tourmaline, sieving, adding lanthanum oxide, and uniformly mixing to obtain tourmaline powder; the tourmaline powder is modified through fluorosilane to obtain modified negative ion powder; mixing the modified negative ion powder with a dispersing agent and waterborne polyurethane, and performing wet ultrafine grinding to obtain a nano negative ion mother solution; the nano anion mother liquor is mixed with a film-forming agent, triethanolamine and water. After lanthanum oxide is added into tourmaline powder, the self-generating field intensity of the tourmaline powder can be improved, the ionization capacity is improved, and the negative ion yield is increased; the hydrophobic and oleophobic properties of the modified negative ion powder are improved through fluorosilane; due to the hydrophobic and oleophobic properties and good film-forming property, a film layer formed by the negative ion solution is not easy to stain and dissolve, a long-acting negative ion release effect is achieved, and an excellent and lasting antibacterial effect is achieved.
