Problems solved by technology

However, in industrial production, antibacterial materials are added to the ceramic glaze formula, the actual amount of antibacterial materials added is relatively large, and the production cost is too high; and in the production process of ceramic tiles, glaze defects such as glaze shrinkage and glaze cracking are more likely to occur ; Although the surface coating layer method has a good antibacterial effect, there are problems such as complicated preparation methods and poor firmness

Embodiment 1

[0039] The invention provides an antibacterial functional ink and a preparation method thereof, comprising the following steps:

[0040] 1) Weigh the antibacterial material nano-TiO according to the mass ratio of 5:10:80:5 2 Powder, Nano Ag 2 O powder, solvent white mineral oil, and hyperdispersant polyethyl acrylate were placed in a basket mixer and stirred at a speed of 600r / min for 0.5h to mix and disperse the raw materials;

[0041] 2) Place the mixed dispersion after stirring in a 30L horizontal sand mill for sand grinding. The sand grinding efficiency is 20Kg / h, the speed is 1200r / min, and the fineness of the mixed dispersion is D10>0.2μm, D90 0.55~0.65μm, D100<1μm;

[0042] 3) Adjust the surface tension, viscosity, and specific gravity of the mixed dispersion that meets the fineness requirements. The viscosity is finally controlled to 12.7mPa·s, the surface tension is finally controlled to 26.6mN / m, and the specific gravity is finally controlled to 1.083g / cm 3 ;

Abstract

The invention provides antibacterial functional ink as well as a preparation method and an application thereof. The antibacterial functional ink is prepared by the steps: mixing and dispersing an antibacterial material, a solvent and a hyperdispersant according to a mass ratio of (10-40):(50-85):(3-10), grinding, removing iron, regulating the surface tension and viscosity, filtering, thereby obtaining the product. The antibacterial material is any one or a mixture of more than one of nano TiO2 powder, nano ZnO powder and nano Ag2O powder; the solvent is any one or a mixture of more than one of white mineral oil, isopropyl diphenyl and isoparaffin; and the hyperdispersant is a polyacrylate dispersing agent. The antibacterial functional ink is used for preparing antibacterial ceramic bricks. The antibacterial functional ink provided by the invention has the advantages of high dispersity, high stability, low production cost and the like, the usage amount of the antibacterial material can be adjusted at any time when the antibacterial material is printed on the ceramic bricks, and the cost of the material is saved.

Description

technical field [0001] The invention relates to the technical field of novel material manufacturing, in particular to an antibacterial functional ink and its preparation method and application. Background technique [0002] Antibacterial materials have been used by people since ancient times. People found that the water stored in silver and copper containers is not easy to deteriorate. Began to realize that metals such as silver have antibacterial effects. [0003] Antibacterial ceramic tile is a new type of environmentally friendly functional material. While maintaining the original function and decorative effect of ceramic products, it increases the function of disinfection, sterilization and chemical degradation, so that it has functions such as antibacterial, deodorizing, and health care, so it can be widely used. In health, medical, family room, civil or industrial buildings. [0004] At present, the main methods of producing antibacterial ceramic tiles are: (1) intro...
