Problems solved by technology

However, these antibacterial agents cannot be added to rubber and other products as reinforcing agents because they have no reinforcing function.
Ordinary white carbon black can only be added to rubber and other products as an additive or reinforcing agent for ordinary products, and cannot meet the needs of some products that require antibacterial functions

Abstract

The invention relates to an antibacterial composite white carbon black material and a preparation method thereof. Antibacterial white carbon black uses graphene and white carbon black as a substrate and is mixed with one or more of antibacterial elements Zn, Cu, Ag and Ti. The preparation method of the material comprises the following steps of preparation of an antibacterial ion solution, two-stepmixing reaction, solid-liquid separation and drying and post-treatment. In the antibacterial composite white carbon black material, the graphene and the white carbon black are interspersed, gatheringof the material itself can be effectively inhibited, and accordingly the highly dispersed composite material containing nano size of white carbon black is obtained. The novel antibacterial compositewhite carbon black material has the dual functions of antibacterial property and reinforcement, and the demands of come products needing to have an antibacterial function are met. An oxidized graphenesolution of low pH value is adopted as one of reaction raw materials, the problem of waste acid and water treatment is solved, and the material is green and friendly to the environment. In addition,the used raw materials are low in cost, the economic performance-cost ratio is high, the preparation process is simple, and industrial production and application are easy to achieve.

Description

technical field [0001] The invention relates to the field of preparation of highly dispersed antibacterial composite materials, in particular to a preparation method of antibacterial white carbon black composite materials. Background technique [0002] White carbon black is precipitated silica, which is a white non-toxic, amorphous fine powder, which has the characteristics of porosity, high temperature resistance, flame retardancy, light weight and high chemical purity. Strong, thickening, and thixotropic properties are widely used in daily and chemical industries such as rubber, paint, plastics, paint, white pigments, textiles, papermaking, pesticides, synthetic resins, and food additives. [0003] The preparation methods of white carbon black mainly include precipitation method and gas phase method. The most commonly used white carbon black in the market is produced by precipitation method. This method has low production cost and simple process, but the product has large...
