Wear-resistant antibacterial ceramic and processing method thereof

Abstract

The invention relates to wear-resistant antibacterial ceramic and a processing method thereof. The processing method includes the steps that a body material is fired for the first time to form a plainbody, then glaze is applied to the two faces of the plain body to form glaze layers, and firing is conducted for the second time, and then the wear-resistant antibacterial ceramic is obtained, wherein the body material is made of raw materials such as sodium bentonite, coke gemstone, pyrophyllite, dolomite, and the like, the glaze is prepared from silicon dioxide, potassium fluoroaluminate, boronoxide, barium oxide, yttrium oxide, titanium-silicon co-doped graphene, large ball mud and other raw materials. Wherein the second firing comprises three-stage heating and heat preservation and three-stage cooling, each heating and heat preservation is sequentially carried out in an air atmosphere, a nitrogen atmosphere and a hydrogen atmosphere, and the three-stage cooling is natural cooling, rapid cooling and natural cooling. The obtained ceramic product has excellent antibacterial performance and wear resistance, and meets the high-quality requirements of ceramics.

Description

Technical field [0001] The invention belongs to the technical field of ceramic processing and relates to a wear-resistant and antibacterial ceramic and a processing method thereof. Background technique [0002] Ceramics is the collective term for pottery and porcelain. It is also a kind of arts and crafts in our country. As far back as the Neolithic Age, our country already has rough and simple painted pottery and black pottery. Pottery and porcelain have different textures and properties. Pottery is made of clay with high viscosity and strong plasticity as the main raw material. It is opaque, has fine pores and weak water absorption, and the sound is muddy. Porcelain is made of clay, feldspar and quartz, translucent, non-absorbent, anti-corrosion, hard and compact, and the sound of knock is crisp. my country's traditional ceramic arts and crafts, with high quality and beautiful appearance, have high artistic value, and are well-known in the world. [0003] Traditional ceramics ...

Problems solved by technology

[0005] In order to improve the wear resistance and antibacterial performance of ceramics, people try to coat the surface of ceramics, but this will affect the whiteness and other indicators of ceramics, and the aesthetics will deteriorate. Moreover, with the storage or use time of ceramics The coating will be peeled off to varying degrees, and even a small area of ​​peeling will lead to a significant decline in the wear resistance and antibacterial properties of ceramics.

[0006] Patent application CN110451924A discloses a kind of antibacterial Dehua glutinous rice body white porcelain with a cavity and its production method. Al2O3, fused silica, lithium china stone, antibacterial additives, etc. are used as raw materials, and are obtained through simple mixing and firing. The compatibility between the components is not good, and the strength of the obtained product is not good. Bacterial performance is also poor, and poor wear resistance
