1. A sterilizing and fresh-keeping porcelain ware is characterized in that: is composed of the following components by weight percentage, 5-8% of radioactive crystal negative ion water-soluble material; far infrared ore powder 0.5-0.8%; 0.5 to 0.8 percent of tourmaline powder; 1-2% of nano titanium dioxide; 5-7% of sintering agent; 1-1.5% of suspension dispersant; 0.3 to 0.5 percent of defoaming agent and 0.5 to 0.8 percent of flatting agent; 70-85% of glaze water solvent.

2. The preparation process of the sterilizing and fresh-keeping porcelain vessel according to claim 1, which is characterized in that: the method specifically comprises the following steps:

firstly, respectively weighing the following components in percentage by mass: 6% of radioactive crystal negative ion water-soluble material; far infrared ore powder 0.5%; 0.5 percent of tourmaline powder; 2 percent of nano titanium dioxide; 6% of sintering agent; 1% of a suspension dispersant; 0.5 percent of defoaming agent and 0.5 percent of flatting agent; glaze water solvent 83%;

secondly, mixing the radioactive crystal negative ion water-soluble material, far infrared ore powder, tourmaline powder, nano titanium dioxide, sintering agent and flatting agent, fully stirring for 5-10 minutes, mixing into a liquid, pouring the liquid and glaze water solvent into a stirring kettle, stirring and dispersing uniformly, and adding a suspension dispersant and a defoaming agent into the discharged mixture to obtain a raw material of the porcelain ware;

and step three, uniformly stirring the raw materials of the porcelain ware, and sintering the raw materials into the porcelain ware at a high temperature of 1330 ℃.

Technical Field

The invention belongs to the technical field of ceramic utensils, and particularly relates to a ceramic utensil with self-sterilization and fresh-keeping functions.

Background

Ceramic utensils are widely used in daily life, and the invention is developed based on the common material components of most of the existing ceramic utensils without antibacterial and fresh-keeping properties.

Disclosure of Invention

The invention aims to provide a sterilizing and fresh-keeping porcelain vessel which is safe to use, and effectively resists and inhibits bacteria aiming at the defects of the prior art.

The invention is realized by the following technical scheme: a sterilizing and fresh-keeping porcelain ware is characterized in that: is composed of the following components by weight percentage, 5-8% of radioactive crystal negative ion water-soluble material; far infrared ore powder 0.5-0.8%; 0.5 to 0.8 percent of tourmaline powder; 1-2% of nano titanium dioxide; 5-7% of sintering agent; 1-1.5% of suspension dispersant; 0.3 to 0.5 percent of defoaming agent and 0.5 to 0.8 percent of flatting agent; 70-85% of glaze water solvent.

The invention also aims to provide a preparation process of the sterilizing and fresh-keeping porcelain vessel, which comprises the following steps:

firstly, respectively weighing the following components in percentage by mass: 6% of radioactive crystal negative ion water-soluble material; far infrared ore powder 0.5%; 0.5 percent of tourmaline powder; 2 percent of nano titanium dioxide; 6% of sintering agent; 1% of a suspension dispersant; 0.5 percent of defoaming agent and 0.5 percent of flatting agent; glaze water solvent 83%.

And secondly, mixing the radioactive crystal negative ion water-soluble material, far infrared ore powder, tourmaline powder, nano titanium dioxide, sintering agent and flatting agent, fully stirring for 5-10 minutes, mixing into a liquid, pouring the liquid and glaze water solvent into a stirring kettle, stirring and dispersing uniformly, and adding a suspension dispersant and a defoaming agent into the discharged mixture to obtain the raw material of the porcelain ware.

And step three, uniformly stirring the raw materials of the porcelain ware, and sintering the raw materials into the porcelain ware at a high temperature of 1330 ℃.

When the nano titanium dioxide absorbs energy in sunlight or other light sources, electrons on the surfaces of the particles are activated and escape from the original orbit, positive holes are generated on the surfaces of the particles, the escaped electrons have strong reducibility, the holes have strong oxidizability, and the electrons and the holes react with water vapor in the air to generate active oxygen and hydroxyl radicals; the active oxygen and the hydroxyl radical can oxidize and decompose most organic matters, pollutants, odor, bacteria and the like into harmless carbon dioxide and water.

Compared with the prior art, the solvent has strong sterilization function, can continuously release more than 5000 negative ions per second, and plays a role in keeping the articles in the vessel fresh.
