Problems solved by technology

Zirconium phosphate-loaded silver antibacterial agent is a commonly used inorganic antibacterial agent, but although the existing zirconium phosphate-loaded silver antibacterial agent has certain antibacterial effect, after it is applied in ceramics, zirconium phosphate-loaded silver antibacterial agent has no effect on the mechanical properties of ceramics. There is no promotion effect, and at the same time, when the addition of zirconium phosphate-loaded silver antibacterial agent is increased in order to improve the antibacterial effect, the thermal shock resistance of ceramics will also be reduced

Abstract

The invention discloses antibacterial domestic ceramics, and relates to the technical field of ceramics. The antibacterial domestic ceramics contains zirconium phosphate / sodium alginate modified attapulgite compound silver-carrying antibacterial agent of which the mass is 6-8%. The prepared antibacterial domestic ceramics not only has excellent thermal shock resistance and impact resistance strength, but also has a significant antibacterial effect and long germicidal duration time.

Description

technical field [0001] The invention belongs to the technical field of porcelain, and in particular relates to an antibacterial daily-use ceramic. Background technique [0002] Daily-use ceramics refer to household porcelain used in people's daily life, including tableware, tea set, coffee set, wine set, table set, etc. Daily-use ceramics are popular because of the following advantages: 1) easy to wash and keep clean; 2) good thermal stability and slow heat transfer; used to hold boiling water or scalding food, it is not too hot to handle. 3) The chemical properties are stable and durable; 4) Porcelain has very few pores and low water absorption; use daily-use porcelain to store food, and after sealing it tightly, it can prevent the moisture in the food from volatilizing, penetrating and external bacteria; 5) Color painting The decoration is rich and colorful, especially high-temperature glaze and blue and white decoration, which are free of lead poisoning hazards, can be u...
