Problems solved by technology

Currently, Ag + The main problem of ionic antibacterial ceramics is that, with Ag + The ions are gradually consumed, and the antibacterial effect decreases significantly. At the same time, when the Ag in the antibacterial agent + When the ion content exceeds 3%, the product quality is difficult to guarantee, and the production cost is also high

Abstract

The present invention relates to an infrared radiant ceramic glazed layer and its preparation method. The main composition of said glazed layer in includes potash feldspar, SiO2, CaCo3, ZnO, talcum, ZrSiO4, clay BaCO3, opaque frit, colouring agent and infrared radiannt ceramic powder. The invention adopts ceramic processing technique, and makes said materials into the invented infrared radiat ceramic glazed layer with the obvious bacteria-inhibiting action for mould, Gram-positive bacterium and Gram-negative bacteruim, and its bacteria-inhibiting rate is up to 91.87%-100%. It can be used in building ceramics, specially used in the places of kitchen, toilet, hospital, infant school and others, so that it possesses strong practicability.

Description

technical field [0001] The invention relates to an infrared radiation ceramic glaze layer with antibacterial function and a preparation method thereof, belonging to the field of building materials. Background technique [0002] For a long time, traditional building materials generally have the problem of single function and use, and it is difficult to meet people's requirements for improving the quality of living and working environments. Since the early 1990s, when Professor Ryoichi Yamamoto of the University of Tokyo proposed the new concept of ecological environment materials, the study of ecological building materials with new functions and effects such as air purification, antibacterial, mildew resistance, humidity control, heat preservation, and infrared radiation has become a building material. A new direction of development. At present, Japan has developed Ag + Various antibacterial materials such as ionic antibacterial materials, and use the above antibacterial ma...
