Description
Technical Field
The invention belongs to the technical field of ceramic cup preparation, and particularly relates to an antibacterial daily ceramic cup and a preparation method thereof.
Background
The ceramic is widely applied to the fields of tableware, decoration and the like due to the characteristics of hard, fine and high temperature resistance and the like, and the use of the ceramic is used for expanding the aspects of our life. With the progress of social civilization and the change of environment, people do not meet the common functions of the traditional ceramics, such as beautiful appearance, durability and the like, and more hopefully, the ceramic has the functions of sterilization, disinfection, deodorization and the like, especially the daily ceramic products.
The prior antibacterial ceramic products are most commonly made of silver antibacterial ceramic and titanium antibacterial ceramic. The silver antibacterial ceramic has good sterilization effect, but needs large silver ion quantity and high production cost, and the silver ions volatilize during high-temperature firing, so that the antibacterial effect is poor; in addition, modern scientific research has found that silver ions and gold ions kill bacteria, but also human cells, and this finding has led to concern about whether long-term use of silver-based antimicrobial products is detrimental to the body. The titanium antibacterial ceramic has poor antibacterial effect during high-temperature firing, and can be sterilized only by photocatalysis. In addition, most of silver antibacterial ceramics are applied to sanitary ware, because the firing temperature of the sanitary ware is low, the antibacterial effect of silver antibacterial ceramics in the low temperature is good, but the application effect on daily high-temperature ceramics is poor, and the following defects exist: (1) the antibacterial effect is poor, (2) the color is limited, (3) the cost is high, and (4) the safety factor of human body is questioned.
Therefore, it is necessary to explore a novel antibacterial ceramic cup for daily use.
Disclosure of Invention
The purpose of the invention is that: provides an antibacterial daily ceramic cup. The antibacterial daily ceramic cup has antibacterial and bacteriostatic capacities; the invention also provides a preparation method thereof.
The antibacterial daily ceramic cup comprises a green body layer, a ground glaze layer and an antibacterial layer; the antibacterial layer consists of the following raw materials in parts by weight: 15-17 parts of bauxite, 9-12 parts of wollastonite, 5-7 parts of potassium feldspar, 18-19 parts of pyrophyllite, 2-3 parts of single-walled carbon nanotubes, 6-8 parts of nano magnesium oxide, 3-5 parts of nano zinc molybdate and 1-2 parts of nano titanium nitride.
Preferably, the antibacterial layer is composed of the following raw materials in parts by weight: 16 parts of bauxite, 11 parts of wollastonite, 5 parts of potassium feldspar, 19 parts of pyrophyllite, 2.5 parts of single-walled carbon nanotubes, 7 parts of nano magnesium oxide, 5 parts of nano zinc molybdate and 2 parts of nano titanium nitride.
Wherein:
the diameter of the single-walled carbon nanotubes was 5 μm.
The antibacterial layer has an antibacterial effect by adding a mixture consisting of single-wall carbon nanotubes, nano magnesium oxide, nano zinc molybdate and nano titanium nitride. When the single-wall carbon nano tube is in direct contact with bacteria, the morphology of the bacterial cells is distorted, the integrity of cell membranes is damaged, the bacteria die and intracellular substances flow out, and the bacteria lose functions, so that the sterilization effect is realized; the nano magnesium oxide reacts with oxygen, and the oxygen is subjected to reduction reaction under the catalysis of oxygen vacancies on the surface of the nano magnesium oxide to generate peroxy ions, wherein the peroxy ions have strong oxidizing property and can induce cell membrane damage so as to destroy amino acid, nucleotide metabolism and cellular enzyme in cells, thereby playing a role in sterilization; zn in nano zinc molybdate 2+ Positively charged, and negatively charged bacterial cell membranes, which attract each other due to coulomb force, to cause Zn to react with each other 2+ Penetrating through cell membrane, entering into bacterial thallus to react with sulfhydryl group on thallus protein to destroy activity of synthetase, interfere synthesis of bacterial DNA, and cause bacterial death to further perform bactericidal effect; the existence of the nano titanium nitride can reduce the adhesion quantity of the surface of the ceramic cup to bacteria.
The blank layer consists of the following raw materials in parts by weight: 27-31 parts of montmorillonite, 18-20 parts of diaspore, 12-15 parts of quartz sand, 8-10 parts of red mud, 13-15 parts of andalusite, 6-8 parts of medical stone, 7-9 parts of diopside, 5-8 parts of calcite and 3-6 parts of strontium carbonate.

The firing stability of the green body is ensured by additionally adding the mixture of medical stone, diopside, calcite and strontium carbonate into the green body layer. Because the medical stone has high biological activity and contains microelements, macroelements and rare earth elements which are beneficial to human bodies, the medical stone is added into a green body of the antibacterial daily ceramic cup. The diopside is also added into the green body of the antibacterial daily ceramic cup, the addition of the diopside can reduce the sintering temperature of the green body, the sintering period is shortened, the introduction of the calcite reduces the sintering shrinkage rate of the green body, calcium oxide in the calcite reacts with aluminum silicon in a liquid phase at high temperature to generate anorthite, and the sintering shrinkage of the green body is reduced; because the decomposition temperature of strontium carbonate is lower, strontium oxide generated by the decomposition of strontium carbonate at high temperature can endow the green body with higher wear resistance, toughness and whiteness.

The adaptability of the blank glaze is increased by adding a mixture of spodumene, illite, talcum, hydroxyapatite, tin oxide and lanthanum oxide in the ground glaze layer. Spodumene is added into the base glaze layer, so that the firing temperature can be reduced, the thermal expansion coefficient of the base glaze layer can be reduced, and the adaptability of the blank glaze is improved. The addition of illite can increase the stability of the base glaze in the firing stage and reduce the occurrence of firing defects. And the talcum forms a liquid phase in the sintering process, fills the pores, and improves the density of the prepared ground glaze. The addition of hydroxyapatite makes the ground coat possess excellent biocompatibility and bioactivity, and in addition, the ground coat interacts with glass phase to reduce the linear shrinkage of ceramic. Tin oxide is added as an opacifier to improve the whiteness and abrasion resistance of the base glaze. The lanthanum oxide can reduce the variety of grain boundaries in the glaze, reduce the influence of the grain boundaries on the glaze performance, reduce the difference of expansion coefficients of the blank glaze, eliminate partial internal stress and improve the rapid cooling and rapid heating resistance of the glaze layer.
