Problems solved by technology

[0003] Sanitary ware is easy to adhere to dirt, which not only affects the appearance, but also becomes a breeding ground for bacteria to grow and multiply
If the dirt and bacteria are not removed in time, people's health will be endangered.
201310022848.X announced a self-cleaning glaze for sanitary ware, which enhances the ease of cleaning by applying a self-cleaning glaze on the outer layer of opaque glaze, which increases the production process and production costs
201310450589.0 announced a method for preparing antibacterial sanitary ceramics, adding nano-silver as an antibacterial agent to improve the antibacterial properties of sanitary ceramics. Nano-silver is easily oxidized and blackened during firing, which affects the whiteness of glaze

Abstract

The invention provides an easy-to-clean and antibacterial sanitary ceramic and a preparation method thereof. The ceramic is prepared from, by mass, 77-97 parts of ceramic glaze, 1-5 parts of inorganic antibacterial material, 5-15 parts of far infrared radiation material and 1-3 parts of sepiolite mineral nano-fiber. The inorganic antibacterial material is an inorganic composite antibacterial agent or inorganic silver antibacterial agent. The far infrared radiation material is a compound of a natural mineral material and a rare earth material. The sepiolite mineral nano-fiber is a product obtained after sepiolite is crushed through an air-current mill. The easy-to-clean performance and the antibacterial performance of the sanitary ceramic are obviously improved, and antibacterial and easy-to-clean functionalization of a glaze surface is achieved on the basis that production cost is not increased.

Description

technical field [0001] The invention relates to sanitary ceramics with easy-to-clean and antibacterial functions, in particular to super-hydrophilic and easy-to-clean sanitary ceramic glazes with antibacterial functions. Background technique [0002] With the development of rapid industrialization and urbanization, my country's sanitary ceramics industry has also developed rapidly. Since the early 1990s, my country's production of sanitary ceramics has been ranked first in the world. Especially in the last 10 years, with the large-scale industrial production, my country's sanitary ceramics has emerged in Guangdong, Fujian, Sichuan and Jiangxi and other major sanitary ceramic production areas, making my country a major producer and exporter of sanitary ceramics in the world. In 2014, the output of my country's sanitary ceramics reached 197 million pieces, and the export volume was about 76.8 million pieces, with an export value of 3.205 billion US dollars. However, in my co...
