Abstract

The invention relates to a calcium carbonate composite germicide and a preparation method thereof, and is characterized in that: a calcium carbonate nano-assembling ball material and nano liver are taken as the raw materials, proper amount of surfactant is added for being taken as a coupling agent and a dispersant, then the environment-protective nano composite germicide with high efficiency is prepared. By the synergy of the calcium carbonate nano material and the nano liver, the composite germicide not only can realize the greatly improved bactericidal potence of the nano liver and reduce the dosage of the nano liver and the consumption of the noble metal resource, but also can fully develop the advantages of the carbonate composite mineral resources in places such as ChiZhou of China and improve the added value of the carbonate composite mineral resources.

Description

technical field [0001] The invention relates to a bactericide compounded with calcium carbonate nanomaterials and a preparation method thereof. The composite fungicide has the functions of antibacterial, deodorizing and partially absorbing ultraviolet rays, and can be used in the sterilization treatment of ceramic products, the disinfection of daily necessities, and the industries of feminine hygiene products, medicine and cosmetics, and belongs to the fields of material chemistry and environmental chemistry. Background technique [0002] In recent years, with the development of ultra-fine calcium carbonate, complex structure and surface modification technology, the application value of calcium carbonate is rapidly increasing, and new products emerge in endlessly. Nano-calcium carbonate is more widely used because of its advantages of small particle size, large specific surface area, high surface activity and good dispersion performance. The research on preparation technolo...
