Problems solved by technology

As a health product that directly contacts with the human body, the appearance of antibacterial function is undoubtedly a deeper reflection of its value. There is no antibacterial purple sand in the market at this stage, and more is the promotion of the antibacterial properties of purple sand itself. Although It itself has antibacterial properties, but the antibacterial rate is low, and has no practical use value

Abstract

The invention provides antibacterial purple sand which takes a purple sand base material and an antibacterial material as raw materials, the antibacterial material takes tetrapod-like zinc oxide, ethylene glycol polyoxyethylene ether, lanthanum oxide and cerium oxide as main raw materials, and the antibacterial purple sand is prepared by the following steps: dissolving lanthanum oxide and cerium oxide and then adjusting the pH value to 7-9. after combustion, adding into a turbid liquid composed of tetrapod-like zinc oxide, ethylene glycol polyoxyethylene ether and water, drying, firing, and grinding with a composite additive and ethylene glycol polyoxyethylene ether to obtain the product. The purple sand base material and the antibacterial material can be well fused, the obtained antibacterial purple sand has good antibacterial performance, the antibacterial performance on staphylococcus aureus reaches 99.99%, the forming performance and using performance of the purple sand are not affected due to addition of the antibacterial material, and the obtained antibacterial purple sand is moderate in water absorption rate, the thermal shock resistance is good, lead and cadmium are not contained, the deformation of the product is small, leakage is avoided, and the use performance is good.

Description

technical field [0001] The invention belongs to the technical field of purple sand, and in particular relates to an antibacterial purple sand and a preparation method thereof. Background technique [0002] Zisha is a unique mineral resource in China, hidden deep in the mountainside. Zisha pottery has been used as the first choice vessel for cooking and brewing tea in China for more than 1,000 years. It is a perfect combination of practicality and art, and has always been loved by literati. Purple sand not only does not contain any harmful substances, but also is rich in various minerals that are beneficial to human health. When firing purple sand, it does not need to be mixed with other raw materials, so it is not subject to other external pollution. Purple sand is rich in a variety of trace elements needed by the human body. Therefore, it can decompose fat in food and lower cholesterol. It is good for health care and disease prevention, preventing premature aging, Alzheime...
