Problems solved by technology

[0002] Environmental pollution has become an important factor that endangers human health. Modern people live and work indoors for a long time, and the indoor air quality caused by human living and decoration pollution has always been a problem. Conventional disinfection and sterilization methods are either effective but not durable, or bring secondary pollution
At present, the reported technology mainly focuses on surface coating. This technology has poor durability and loses its bactericidal effect after cleaning or rubbing in a short period of time.

Abstract

The invention belongs to the technical field of building materials, and particularly relates to a photocatalytic sterilization self-cleaning ink-jet micro-powder brick and a preparation method thereof. The photocatalytic sterilization self-cleaning ink-jet micro-powder brick is prepared from a blank and a nano-glaze, wherein the blank comprises kaolin, montmorillonite, potassium feldspar, albite, talc and pyrophyllite; the nano-glaze comprises nano titanium dioxide, nano zinc oxide, aluminium oxide, calcium phosphate and methylcellulose. The sterilization glaze is uniformly distributed on all levels of the photocatalytic sterilization self-cleaning ink-jet micro-powder brick and embedded into the blank body, so that the sterilization effect is lasting, and the defects of short sterilization validity and failures after abrasion, caused by the reason that the glaze coats like products in a coating manner, are avoided.
